Front Seats Manual Seats {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver’s seat only when the vehicle is not moving. To move a manual seat forward or rearward: 1. Lift the bar to unlock the seat. 2. Slide the seat to the desired position and release the bar.
Power Seats Driver’s Seat with Power Seat Control, Power Recline, and Power Lumbar shown On a vehicle with power seats, the controls used to operate them are located on the outboard side of the seats. 10 To adjust the seat, do any of the following: • Move the seat forward or rearward by sliding the control forward or rearward. • Raise or lower the front part of the seat cushion by moving the front of the control up or down.
Manual Lumbar Power Lumbar If your vehicle has this feature, the knob is located on the front of the driver seat lower cushion on the outboard side. Turn the knob forward to increase, and rearward to decrease lumbar support. If the seats have power lumbar, the controls used to operate this feature are located on the outboard side of the seats. • To increase lumbar support, press and hold the front of the control. • To decrease lumbar support, press and hold the rear of the control.
Release the control when the lower seatback reaches the desired level of lumbar support. Your vehicle may have a memory function which allows seat settings to be saved and recalled. See Memory Seat, Mirrors, and Pedals on page 13 for more information. Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support. Adjust the seat as needed. I (Heated Seatback): Press this button to turn on the heated seatback.
Memory Seat, Mirrors, and Pedals Your vehicle may have the memory package. The controls for this feature are located on the driver’s door panel, and are used to program and recall memory settings for the driver’s seat, outside mirrors, and the adjustable throttle and brake pedal. To save your positions in memory, do the following: 1. Adjust the driver’s seat, including the seatback recliner and lumbar, both outside mirrors, and the throttle and brake pedals to a comfortable position.
To stop recall movement of the memory function at any time, press one of the power seat controls, memory buttons, power mirror buttons, or adjustable pedal switch. Easy Exit Seat If something has blocked the driver’s seat and/or the adjustable pedals while recalling a memory position, the driver’s seat and/or the adjustable pedals recall may stop working. If this happens, remove the obstruction and press the appropriate control for the area that is not responding for two seconds.
Reclining Seatbacks Manual Reclining Seatbacks If the seats have manual reclining seatbacks, the lever used to operate them is located on the outboard side of the seat(s). {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver’s seat only when the vehicle is not moving.
To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked. Power Reclining Seatbacks If the seats have power reclining seatbacks, the control used to recline them is located on the outboard side of the seat behind the power seat control. • To recline the seatback, tilt the top of the control rearward.
{CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
Head Restraints Pull the head restraint up to raise it. To lower the head restraint, press the release button, located on the top of the seatback, while you push the head restraint down. The second row seats have head rests that can be adjusted up and down. Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head. This position reduces the chance of a neck injury in a crash.
Seatback Latches Center Seat The front seatbacks tilt forward to allow access to the rear of the cab. Your vehicle may have a front center seat. The seatback doubles as an armrest and cupholder/storage area for the driver and passenger when the center seat is not used. Do not use it as a seating position when the seatback is folded down. To tilt the seatback forward, lift the lever located on the outboard side of the seat cushion.
Rear Seats Rear Seat Operation (Full Bench) Folding the Rear Seat To fold the seat up, do the following: Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts. Always unbuckle the safety belts and return them to their normal stowed position before folding a rear seat. 1. Pull up on the front of the seat cushion while pulling down on the release strap, located under the seat cushion. 20 2.
Rear Seat Operation (Split Bench) Folding Rear Seat On a vehicle with a second row 60/40 split seat either side of the rear seat may be folded for added cargo space. Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts. Always unbuckle the safety belts and return them to their normal stowed position before folding a rear seat.
Safety Belts CAUTION: Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. (Continued) Do not allow people to ride in, or on, any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly. {CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle.
Your vehicle has indicators to remind you and your passengers to buckle your safety belts. See Safety Belt Reminder Light on page 255 and Passenger Safety Belt Reminder Light (1500 Series) on page 255. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. In most states and in all Canadian provinces, the law says to wear safety belts. Here is why: They work. You never know if you will be in a crash. If you do have a crash, you do not know if it will be a bad one.
Put someone on it. 24 Get it up to speed. Then stop the vehicle. The rider does not stop.
The person keeps going until stopped by something. In a real vehicle, it could be the windshield... or the instrument panel...
Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after an accident if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.
Q: If I am a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you are in an accident — even one that is not your fault — you and your passengers can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h).
Driver Position Lap-Shoulder Belt The driver has a lap-shoulder belt. Here is how to wear it properly. 1. Close and lock the door. 2. Adjust the seat so you can sit up straight. To see how, see “Seats” in the Index. 3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. 28 The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 4.
6. To make the lap part tight, pull up on the shoulder belt. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Q: What is wrong with this? {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. A: The shoulder belt is too loose. It will not give nearly as much protection this way.
Q: What is wrong with this? {CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force at your abdomen. This could cause serious or even fatal injuries. The lap belt should be worn low and snug on the hips, just touching the thighs. A: The lap belt is too loose. It will not give nearly as much protection this way.
Q: What is wrong with this? {CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place.
Q: What is wrong with this? {CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What is wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer/retailer to fix it. A: The belt is twisted across the body.
Shoulder Belt Height Adjustment Shoulder belt height adjusters are available for the driver and right front passenger seating positions. Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash.
On the extended cabs, push down on the release button (A) and move the height adjuster to the desired position. Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. Extended Cab You can move the adjuster up just by pushing up on the shoulder belt guide.
The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly. Center Front Passenger Position (Regular Cab) Right Front Passenger Position The center front passenger’s safety belt works the same way as the driver’s safety belt — except for one thing.
Center Front Passenger Position (Crew and Extended Cab) Lap Belt Your vehicle may have a center front seating position. To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position, and release it the same way as the lap part of a lap-shoulder belt. If the belt is not long enough, see Safety Belt Extender on page 45. When you sit in a center front seating position, you have a lap safety belt, which has no retractor.
Rear Seat Passengers Lap-Shoulder Belt It is very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. All rear seat positions have lap-shoulder belts. Here is how to wear one properly. Rear passengers who are not safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. 1.
2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 45. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 3. To make the lap part tight, pull up on the shoulder part.
The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The safety belt locks if there is a sudden stop or a crash. {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. The lap part of the belt should be worn low and snug on the hips, just touching the thighs.
Rear Safety Belt Comfort Guides Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head. There is one guide for each outboard passenger position in the rear seat. Here is how to install a comfort guide to the shoulder belt: 1. Remove the guide from its storage clip on the interior body.
2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
{CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. 4. Buckle, position, and release the safety belt as described in Rear Seat Passengers on page 39. Make sure that the shoulder belt crosses the shoulder.
Safety Belt Pretensioners Safety Belt Extender Your vehicle has safety belt pretensioners for the driver and right front passenger. Although you cannot see them, they are part of the safety belt assembly. They help tighten the safety belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met.
Child Restraints Older Children Q: What is the proper way to wear safety belts? A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
Q: What if a child is wearing a lap-shoulder {CAUTION: Never do this. Here two children are wearing the same belt. The belt cannot properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. belt, but the child is so small that the shoulder belt is very close to the child’s face or neck? A: If the child is sitting in a seat next to a window, move the child toward the center of the vehicle.
{CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs.
Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
{CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby does not weigh much — until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb (5.5 kg) baby will suddenly become a 240 lb (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint.
{CAUTION: Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide.
Q: What are the different types of add-on child restraints? {CAUTION: A: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. For most basic types of child restraints, there are many different models available.
Child Restraint Systems {CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries.
A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. 54 A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields.
Q: How Should I Use a Child Restraint? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. To help reduce injuries, an add-on child restraint must be secured in the vehicle. With built-in or add-on child restraints, the child has to be secured within the child restraint.
Securing an Add-on Child Restraint in the Vehicle {CAUTION: A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Make sure the child restraint is properly installed in the vehicle using the vehicle’s safety belt or LATCH system, following the instructions that came with that restraint, and also the instructions in this manual. To help reduce the chance of injury, the child restraint must be secured in the vehicle.
Securing the Child Within the Child Restraint There are several systems for securing the child within the child restraint. One system, the three-point harness, has straps that come down over each of the infant’s shoulders and buckle together at the crotch. The five-point harness system has two shoulder straps, two hip straps, and a crotch strap. A shield may take the place of hip straps. A T-shaped shield has shoulder straps that are attached to a flat pad which rests low against the child’s body.
Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We recommend that children be secured in a rear seat, including: an infant or a child riding in a rear-facing child restraint; a child riding in a forward-facing child seat; an older child riding in a booster seat; and children, who are large enough, using safety belts. A label on your sun visor says, “Never put a rear-facing child seat in the front.
CAUTION: (Continued) We recommend that rear-facing child restraints be transported in vehicles with a rear seat that will accommodate a rear-facing child restraint, whenever possible. {CAUTION: A child in a child restraint in the center front seat can be badly injured or killed by the right front passenger’s airbag if it inflates. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in the rear seat.
If your vehicle has the passenger sensing system or the airbag off switch and you need to secure a rear-facing child restraint in the right front passenger’s seat, the passenger’s frontal airbag must be off.
In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. The child restraint manufacturer will provide you with instructions on how to use the child restraint and its attachments. The following explains how to attach a child restraint with these attachments in your vehicle. Lower Anchors Not all vehicle seating positions or child restraints have lower anchors and attachments or top tether anchors and attachments.
Top Tether Anchor Your child restraint may have a single tether (A) or a dual tether (C). Either will have a single attachment (B) to secure the top tether to the anchor. Some child restraints that have a top tether are designed for use with or without the top tether being attached. Others require the top tether always to be attached. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached.
i (Top Tether Anchor): Lower Anchor and Top Tether Anchor Locations Seating positions with top tether anchors. i (Top Tether Anchor): Seating positions with top tether anchors. j (Lower Anchor): Seating positions with two lower anchors. Crew and Extended Cab Rear Seat Regular Cab Front Seat Do not install a child restraint in the center front seat position. See Securing a Child Restraint in the Center Front Seat Position on page 74 for more information.
For regular cab models, there is an anchor symbol on the trim covers to assist you in locating the top tether anchors. Regular Cab Do not install a child restraint in the center seat position. See Securing a Child Restraint in the Center Front Seat Position on page 74 for more information. For regular cab models, the top tether anchors are located under trim covers on the back panel behind the passenger seat. Remove the trim plug to access the anchor.
Be sure to read the instructions following to properly install a child restraint using these loops. Do not secure a child restraint in the front passenger’s position if your vehicle has rear seats, if a national or local law requires that the top tether be attached, or if the instructions that come with the child restraint say that the top tether must be attached. There is no place to attach the top tether in this position.
Securing a Child Restraint Designed for the LATCH System {CAUTION: If a LATCH-type child restraint is not attached to anchors, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchors, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual.
{CAUTION: Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. Secure any unused safety belts behind the child restraint so children cannot reach them. Pull the shoulder belt all the way out of the retractor to set the lock, if your vehicle has one, after the child restraint has been installed. Be sure to follow the instructions of the child restraint manufacturer.
Regular Cab Models 1. If the child restraint manufacturer recommends that the top tether be attached, attach and tighten the top tether to the top tether anchor, if your vehicle has one. Refer to the child restraint instructions and the following steps: 1.1. Pull the passenger seatback forward by pulling the recliner handle upward to access the top tether anchor. See Reclining Seatbacks on page 15 for additional information. 1.2. Find the top tether anchor. 1.3. Remove the trim cover to expose the anchor.
2. See Securing a Child Restraint in the Right Front Seat Position (With Airbag Off Switch) on page 75 or Securing a Child Restraint in the Right Front Seat Position (With Passenger Sensing System) on page 81 or Securing a Child Restraint in the Right Front Seat Position (Heavy Duty Crew Cab Only) on page 85 for instructions on installing the child restraint using the safety belts. 3. Push and pull the child restraint in different directions to be sure it is secure. Crew and Extended Cab Models 1.
2. If the child restraint manufacturer recommends that the top tether be attached, attach and tighten the top tether to the top tether anchor (loop), if your vehicle has one. Refer to the child restraint instructions and the following steps: Example — Rear Driver’s Side Position Example — Rear Driver’s Side Position 70 2.1. When using a child restraint with a top tether in the rear driver side position: A. Raise the head rest. B.
2.2. When using a child restraint with a top tether in the rear center position: A. Route the top tether (B) through the center loop (D), and behind the inboard passenger side head rest post. B. Attach the top tether (B) to the top tether anchor (loop) at the rear passenger side seating position. 2.3. When using a child restraint with a top tether in the rear passenger position: A. Raise the head rest. B.
Securing a Child Restraint in a Rear Seat Position Extended Cab and Crew Cab There is limited space in the rear seating of an extended cab model. If you want to secure a child restraint in a rear seating position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1.
4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 5. To tighten the belt, push down on the child restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor. If you are using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
6. If your child restraint manufacturer recommends using a top tether, attach and tighten the top tether to the top tether anchor. Refer to the instructions that came with the child restraint and to Lower Anchors and Tethers for Children (LATCH) on page 60. 7. Push and pull the restraint in different directions to be sure it is secure. To remove the child restraint, if the top tether is attached to a top tether anchor, disconnect it. Unbuckle the vehicle’s safety belt and let it go back all the way.
Securing a Child Restraint in the Right Front Seat Position (With Airbag Off Switch) Your vehicle has a right front passenger airbag. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 58. If one of the switches pictured in the following illustrations is located in your glove box, your vehicle has an airbag on-off switch that you can use to manually turn on or off the right front passenger’s airbag.
A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag.
{CAUTION: If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger’s airbag could inflate even though the switch is off.
You will be using the lap-shoulder belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. Your vehicle has a right front passenger’s frontal airbag. See Airbag Off Switch on page 100.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, push down on the child restraint, pull the shoulder belt to tighten the lap belt portion, and feed the shoulder belt back into the retractor. If you are using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. You should not be able to pull more of the belt out of the retractor once the lock has been set.
7. If your child restraint manufacturer recommends using a top tether, and the position you are using has a top tether anchor, attach and tighten the top tether to the top tether anchor. Refer to the instructions that came with the child restraint and to Lower Anchors and Tethers for Children (LATCH) on page 60. 8. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, if the top tether is attached to the top tether anchor, disconnect it.
Securing a Child Restraint in the Right Front Seat Position (With Passenger Sensing System) Your vehicle has a right front passenger airbag. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 58. In addition, your vehicle may have a passenger sensing system.
If your vehicle does not have a rear seat that will accommodate a rear-facing child restraint, we recommend that rear-facing child restraints not be transported in your vehicle, even if the airbag is off. If your child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 60. If your vehicle has a rear seat, there is no top tether anchor at the right front seating position.
4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
7. If your child restraint manufacturer recommends using a top tether, and the position you are using has a top tether anchor, attach and tighten the top tether to the top tether anchor. Refer to the instructions that came with the child restraint and to Lower Anchors and Tethers for Children (LATCH) on page 60. 8. Push and pull the child restraint in different directions to be sure it is secure.
If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint. Securing a Child Restraint in the Right Front Seat Position (Heavy Duty Crew Cab Only) If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, check to make sure that the vehicle’s seatback is not pressing the child restraint into the seat cushion.
Never put a rear-facing child restraint in the right front passenger’s seat. Here is why: {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Always secure a rear-facing child restraint in a rear seat. If your child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 60.
4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
If you are using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. You should not be able to pull more of the belt from the retractor once the lock has been set. 7. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle’s safety belt and let it go back all the way.
Airbag System Your vehicle has the following airbags: • A frontal airbag for the driver. • A frontal airbag for the right front passenger. Your vehicle may have the following airbags: • A roof-mounted rollover airbag for the driver and right front passenger. • A roof-mounted rollover airbag for the second row outboard passenger positions.
CAUTION: {CAUTION: Frontal airbags for the driver and right front passenger are designed to deploy in moderate to severe frontal and near frontal crashes. They are not designed to inflate in rollover, rear crashes, or in many side crashes. And, for some unrestrained occupants, frontal airbags may provide less protection in frontal crashes than more forceful airbags have provided in the past.
{CAUTION: {CAUTION: Both frontal and roof-mounted side impact airbags inflate with great force, faster than the blink of an eye. If you are too close to an inflating airbag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position for airbag inflation before and during a crash. Always wear your safety belt even with frontal airbags. The driver should sit as far back as possible while still maintaining control of the vehicle.
There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. Where Are the Airbags? The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light on page 256 for more information. The driver’s airbag is in the middle of the steering wheel.
The right front passenger’s airbag is in the instrument panel on the passenger’s side. If your vehicle has a roof-mounted rollover airbag for the driver and the person seated directly behind the driver, it is located in the ceiling above the side windows.
{CAUTION: If your vehicle has a roof-mounted rollover airbag for the right front passenger and the person directly behind that passenger, it is located in the ceiling above the side windows. 94 If something is between an occupant and an airbag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear.
When Should an Airbag Inflate? The driver’s and right front passenger’s frontal airbags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact exceeds a predetermined deployment threshold. Deployment thresholds take into account a variety of desired deployment and non-deployment events and are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants.
Your vehicle has a seat position sensor which enables the sensing system to monitor the fore and aft position of the driver’s seat. Seat position sensors provide information that is used to determine if the airbags should deploy at a reduced level or at full deployment. Your vehicle may or may not have roof-mounted rollover airbags and a rollover sensor. See Airbag System on page 89.
Dual Stage Airbags What Makes an Airbag Inflate? If your vehicle has frontal airbags with dual stage deployment, the amount of restraint will adjust according to crash severity. Your vehicle has electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. For moderate frontal impacts, these airbags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs.
How Does an Airbag Restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. Airbags supplement the protection provided by safety belts. Airbags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
{CAUTION: When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an airbag deployment, you should seek medical attention.
Airbag Off Switch If one of the switches pictured in the following illustrations is located in your glove box, your vehicle has an airbag on-off switch that you can use to manually turn on or off the right front passenger’s airbag. Your switch may vary slightly. This switch should only be turned to the off position if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Infant.
• The child has a medical condition which, according to the child’s physician, makes it necessary for the child to ride in the front seat so that the driver can constantly monitor the child’s condition. Medical Condition.
{CAUTION: United States Canada To turn off the right front passenger’s airbag, insert your ignition key into the switch, push in, and move the switch to the off position. The word OFF or the off symbol will come on in the passenger airbag status indicator located in the overhead console to let you know that the right front passenger’s airbag is off, after the system check is completed. The airbag off light will come on and stay on to let you know that the right front passenger’s airbag is off.
Passenger Sensing System If your vehicle has one of the indicators pictured in the following illustrations, then your vehicle has a passenger sensing system for the right front passenger’s position, unless there is an airbag off switch located in the glovebox. If there is an airbag off switch, your vehicle does not have a passenger sensing system. See Airbag Off Switch on page 100 for more information.
When the system check is complete, either the word ON or the word OFF, or the symbol for on or the symbol for off, will be visible. See Passenger Airbag Status Indicator on page 258. The passenger sensing system will turn off the right front passenger’s frontal airbag under certain conditions. The driver’s airbags are not part of the passenger sensing system. The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt.
CAUTION: {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag.
The passenger sensing system is designed to turn off the right front passenger’s frontal airbag if: • The right front passenger seat is unoccupied. • The system determines that an infant is present in a rear-facing infant seat. • The system determines that a small child is present in a child restraint. • The system determines that a small child is present in a booster seat. • A right front passenger takes his/her weight off of the seat for a period of time.
If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, check to make sure that the vehicle’s seatback is not pressing the child restraint into the seat cushion. If this happens, slightly recline the vehicle’s seatback and adjust the seat cushion if possible. Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints on page 18.
If a person of adult-size is sitting in the right front passenger’s seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat. If this happens, turn the vehicle off and ask the person to place the seatback in the fully upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended. Restart the vehicle and have the person remain in this position for two to three minutes.
{CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 256 for more on this, including important safety information.
Servicing Your Airbag-Equipped Vehicle Airbags affect how your vehicle should be serviced. There are parts of the airbag system in several places around your vehicle. You do not want the system to inflate while someone is working on your vehicle. Your dealer/retailer and the service manual have information about servicing your vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 669.
Adding Equipment to Your Airbag-Equipped Vehicle Q: Is there anything I might add to the front Q: What if I added a snow plow? Will it keep the airbags from working properly? A: We have designed our airbag systems to work properly under a wide range of conditions, including snow plowing with vehicles that have the optional Snow Plow Prep Package (RPO VYU). But do not change or defeat the snow plow’s “tripping mechanism.
Restraint System Check Checking the Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Keep safety belts clean and dry. See Care of Safety Belts on page 610 for more information. Torn or frayed safety belts may not protect you in a crash.
Replacing Restraint System Parts After a Crash {CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

This device must accept any interference received, including interference that may cause undesired operation. This device complies with RSS-210 of Industry Canada.
If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse, see Fuses and Circuit Breakers on page 618. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty. See your dealer/retailer who can service the PASS-Key® III+ to have a new key made. In an emergency, contact Roadside Assistance.
If you lose or damage your PASS-Key® III+ key, see your dealer/retailer or a locksmith who can service PASS-Key® III+ to have a new key made. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. Starting and Operating Your Vehicle New Vehicle Break-In • Avoid making hard stops for the first 200 miles (322 km) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement.
Ignition Positions Use the key to turn the ignition switch to four different positions. B (ACCESSORY): This position lets things like the radio and the windshield wipers operate while the engine is off. Lengthy operation of features such as the radio in the ACCESSORY ignition position and the RUN position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the ACCESSORY ignition position for a long period of time. C (RUN): This is the position for driving.
Key In the Ignition Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound, when you open the driver’s door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transmission. Also, always remember to lock the doors. The battery could be drained if you leave the key in the ignition while your vehicle is parked.
Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. Your vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components.
Notice: Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, your engine might not perform properly. Any resulting damage would not be covered by your vehicle’s warranty. The switch used to adjust the pedals is located on the instrument panel below the climate control system.
To Use the Engine Coolant Heater Engine Coolant Heater Your vehicle may have an engine coolant heater. ® If your vehicle has the DURAMAX Diesel engine, see the DURAMAX® Diesel manual for more information. In very cold weather, 0°F (−18°C) or colder, the engine coolant heater can help. You will get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.
4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you do not, it could be damaged. How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer/retailer in the area where you will be parking your vehicle.
Automatic Transmission Operation If your vehicle is has an automatic transmission, it has an electronic shift position indicator within the instrument panel cluster. This display comes on when the ignition key is turned to the RUN position. There are several different positions for the shift lever. Hydra-Matic® 4-Speed Automatic Transmission 146 Allison Transmission® or Hydra-Matic® 6-Speed Automatic Transmission See “Range Selection Mode” later in this section.
{CAUTION: {CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. If you have Four-Wheel Drive, your vehicle will be free to roll — even if your shift lever is in PARK (P) — if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear, Two-Wheel Drive High or Four-Wheel Drive High or Four-Wheel Drive Low — not in NEUTRAL. See Shifting Into Park (P) on page 170.
NEUTRAL (N): In this position, your engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed. {CAUTION: Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while your engine is running at high speed.
If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this could appear to be a delayed shift, however the transmission is operating normally. Your vehicle’s transmission uses adaptive shift controls. Adaptive shift controls continually compares key shift parameters to pre-programmed ideal shifts stored in the transmissions computer.
FIRST (1): For the Hydra-Matic® 4-Speed transmission this position reduces vehicle speed even more than SECOND (2) without using the brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission does not shift into first gear until the vehicle is going slowly enough. For an Allison Transmission® or Hydra-Matic® 6-Speed transmission, this position reduces vehicle speed without using your brakes.
To use this feature, do the following: 1. Move the shift lever to the MANUAL MODE (M). 2. Press the plus/minus buttons, located on the steering column shift lever, to select the desired range of gears for your current driving conditions. When MANUAL MODE (M) is selected a number displays next to the M, indicating the current gear. This number is the highest gear that can be used. However, your vehicle can automatically shift to lower gears as it adjusts to driving conditions.
Tow/Haul Mode The tow/haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when towing or hauling heavy loads. The selector button is located on the end of the shift lever. Turn the tow/haul on and off by pressing the button. When the tow/haul is on, a light on the instrument panel cluster will come on. See Tow/Haul Mode Light on page 272 for more information.
Tow/Haul Mode (Allison Transmission® or Hydra-Matic® 6-Speed Automatic Transmission) Turn the tow/haul mode on and off by pressing the button, located on the end of the shift lever. When the tow/haul is on, a light on the instrument panel cluster will come on. See Tow/Haul Mode Light on page 272 for more information. Also see “Tow Haul Mode” under Towing a Trailer on page 449 for more information.
Grade Braking is only active while the Tow/Haul Mode is selected and you are not in the Range Selection Mode. See “Tow/Haul Mode listed previously and Automatic Transmission Operation on page 146 for more information on the Range Selection Mode. Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by automatically implementing a shift schedule that utilizes the engine and transmission to slow the vehicle.
Manual Transfer Case Some delay between shifting and when the indicator light comes on is normal. Recommended Transfer Case Settings Driving Conditions Normal Severe Extreme Transfer Case Settings 2m 4m 4n N YES YES YES Vehicle in Tow* YES *See Recreational Vehicle Towing on page 443 Towing Your Vehicle on page 443 The transfer case shift lever is on the floor to the right of the driver. Use this lever to shift into and out of Four-Wheel Drive.
You might choose Four-Wheel-Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. When operating in Four-Wheel Low, the gear ratio provides additional torque when compared to Four-Wheel-Drive High. The transmission gear shift feel is exaggerated. A parking brake symbol is located next to the N (NEUTRAL) symbol as a reminder to set the parking brake before shifting the transfer case in Neutral.
4 m (Four-Wheel-Drive High): Use this setting when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive your vehicle. This is the best setting to use when plowing snow. You can shift from Two-Wheel-Drive High to Four-Wheel-Drive High or Four-Wheel-Drive High to Two-Wheel-Drive High while the vehicle is moving. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into Four-Wheel-Drive High.
Shifting In or Out of Four-Wheel-Drive Low Notice: Shifting the transfer case into Four-Wheel-Drive Low while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into Four-Wheel-Drive Low while the vehicle is moving faster than 3 mph (5 km/h).
Shifting In or Out of NEUTRAL 1. With the vehicle running and the engine at an idle set the parking brake. 2. Place the transmission into NEUTRAL (N). Shift the transfer case in one continuous motion into or out of the NEUTRAL position. Electronic Transfer Case The transfer case knob is located next to the steering column. Use the dial to shift into and out of four-wheel drive.
4 m (Four-Wheel-Drive High): Use the Four-Wheel-Drive High position when extra traction is needed, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4 n (Four-Wheel-Drive Low): This setting also engages the front axle and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels.
Shifting Into Two-Wheel-Drive High Turn the knob to the Two-Wheel-Drive High position. This can be done at any speed, except when shifting from Four-Wheel-Drive Low. See Shifting Out of Four-Wheel-Drive Low for more information. Shifting Into Four-Wheel Drive Low When Four-Wheel-Drive Low is engaged, vehicle speed should be kept below 45 mph. Extended high-speed operation in Four-Wheel-Drive Low may damage or shorten the life of the drivetrain.
Shifting Out of Four-Wheel-Drive Low To shift from Four-Wheel-Drive Low to Four-Wheel-Drive High, or Two-Wheel-Drive High, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of Four-Wheel-Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel-Drive High, or Two-Wheel-Drive High position.
6. Turn the transfer case dial clockwise to NEUTRAL till it stops and hold it for 10 seconds. Then slowly release the dial to the four low position. The NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 7. If the engine is running, verify that the transmission is in NEUTRAL (N) by shifting the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second. 8. Turn the ignition to ACCESSORY, which will turn the engine off. 9.
Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes. Automatic Transfer Case The transfer case knob is located next to the steering column. For information on StabiliTrak®, see StabiliTrak® System on page 385.
4 m(Four-Wheel-Drive High): Use the Four-Wheel-Drive High position when extra traction is needed, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4 n(Four-Wheel-Drive Low): This setting also engages the front axle and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels.
Shifting Into Four-Wheel-Drive High or AUTO (Automatic Four-Wheel Drive) Turn the knob to the Four-Wheel-Drive High or AUTO position. This can be done at any speed, except when shifting from Four-Wheel-Drive Low, and the indicator light will flash while shifting. It will remain on when the shift is completed. Shifting Into Two-Wheel-Drive High Turn the knob to the Two-Wheel-Drive High position. This can be done at any speed, except when shifting from Four-Wheel-Drive Low.
Shifting Out of Four-Wheel-Drive Low To shift from Four-Wheel-Drive Low to Four-Wheel-Drive High, AUTO or Two-Wheel-Drive High, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of Four-Wheel-Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel-Drive High, AUTO or Two-Wheel-Drive High position.
3. Start the vehicle or turn the ignition to RUN. 4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to Two-Wheel Drive High. 6. Turn the transfer case dial clockwise to NEUTRAL till it stops and hold it for 10 seconds. Then slowly release the dial to the four low position. The NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 7.
Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. A chime sounds and the warning light flashes when the parking brake is applied and the vehicle is moving at least 5 mph (8 km/h). If the ignition is on when the parking brake is released, the brake system warning light goes off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts.
Shifting Into Park (P) CAUTION: {CAUTION: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, use the steps that follow.
Leaving Your Vehicle With the Engine Running {CAUTION: It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. If you have four-wheel drive and your transfer case is in NEUTRAL, your vehicle will be free to roll, even if your shift lever is in PARK (P). So be sure the transfer case is in a drive gear — not in NEUTRAL.
If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission, then you will be able to pull the shift lever out of PARK (P). Parking Over Things That Burn Shifting Out of Park (P) Your vehicle has an automatic transmission shift lock control system which locks the shift lever in PARK (P) when the ignition is in the LOCK. Apply your regular brakes before shifting from PARK (P) when the ignition is in RUN.
Engine Exhaust CAUTION: (Continued) • Your vehicle was damaged when {CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: • The exhaust system sounds strange or different. • Your vehicle gets rusty underneath. • Your vehicle was damaged in a collision. CAUTION: driving over high points on the road or over road debris. • Repairs were not done correctly.
Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust on page 173. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is a garage.
{CAUTION: Four-wheel drive vehicles with the transfer case in NEUTRAL will allow the vehicle to roll, even if the shift lever is in PARK (P). So, be sure the transfer case is in a drive gear — not in NEUTRAL. Always set the parking brake. Follow the proper steps to be sure your vehicle will not move. See Shifting Into Park (P) on page 170. If you are pulling a trailer, see Towing a Trailer on page 449.

Instrument Panel Cluster United States Light Duty Premium version shown. Canada, Uplevel, Base, Heavy Duty Clusters similar. Your instrument cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, about how much fuel you have and many other things you will need to know to drive safely and economically. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information.
Speedometer and Odometer Trip Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Engine Hour Meter Display The Driver Information Center (DIC) can also display the number of hours the engine has run.
Safety Belt Reminder Light When the key is turned to RUN or START, a chime will sound for several seconds to remind people to buckle their safety belts. The driver safety belt light will also come on and stay on for several seconds, then it will flash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is buckled, neither the chime nor the light will come on.
Airbag Readiness Light Airbag Off Light There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensors, the airbag modules, the wiring and the crash sensing and diagnostic module and, if equipped, the passenger sensing system. For more information on the airbag system, see Airbag System on page 89.
This light will go off when you turn the airbag on. See Airbag Off Switch on page 100 for more on this, including important safety information. {CAUTION: If the right front passenger’s airbag is turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inflate and help protect the person sitting there.
If the word ON or the on symbol is lit, it means that the right front passenger’s frontal airbag is enabled (may inflate). See Airbag Off Switch on page 100 for more on this, including important safety information. If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the airbag on-off switch. See your dealer/retailer for service.
{CAUTION: {CAUTION: If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag.
If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system.

Your Driving, the Road, and Your Vehicle Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See Safety Belts: They Are for Everyone on page 22. 378 {CAUTION: Defensive driving really means “Be ready for anything.” On city streets, rural roads, or expressways, it means “Always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes.
Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: • Judgment • Muscular Coordination • Vision • Attentiveness Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving.
According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin, or vodka. It is the amount of alcohol that counts.
But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision.
Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering, and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. See StabiliTrak® System on page 385.
If your vehicle’s engine ever stops while you are driving, brake normally but do not pump the brakes. If you do, the pedal may get harder to push down. If the engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modifications on page 494.
ABS can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down.
Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let antilock work for you. You might feel the brakes vibrate or notice some noise, but this is normal.
If the system fails to turn on or activate, the StabiliTrak® light along with one of the following messages will be displayed on the Driver Information Center (DIC): TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, STABILITRAK OFF, SERVICE STABILITRAK. If these DIC messages appear, make sure the StabiliTrak® system has not been turned off using the StabiliTrak® on/off button. Then turn the steering wheel clockwise from the nine o’clock position to the three o’clock position.
Traction control and StabiliTrak® can be turned on by pressing and releasing the StabiliTrak® button if not automatically shut off for any other reason. When the TCS or StabiliTrak® system is turned off, the StabiliTrak® light and the appropriate TCS off or StabiliTrak® off message will be displayed on the DIC to warn the driver. Your vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system.
Traction Control Operation The traction control system is part of the StabiliTrak® system. Traction control limits wheel spin by reducing engine power to the wheels (engine speed management) and by applying brakes to each individual wheel (brake-traction control) as necessary. The traction control system is enabled automatically when you start your vehicle. It will activate and the StabiliTrak® light will flash if it senses that any of the wheels are spinning or beginning to lose traction while driving.
Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Steering Tips It is important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves.
Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking — if you can stop in time. But sometimes you cannot; there is not room. That is the time for evasive action — steering around the problem.
Off-Road Recovery Passing You may find that your right wheels have dropped off the edge of a road onto the shoulder while you are driving. The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again.
So here are some tips for passing: • Drive ahead. Look down the road, to the sides, and to crossroads for situations that might affect your passing patterns. If you have any doubt whatsoever about making a successful pass, wait for a better time. • Watch for traffic signs, pavement markings, and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it is all right to pass, providing the road ahead is clear.
• Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. • Do not overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not flashing, it may be slowing down or starting to turn. • If you are being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right.
If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your driving to these conditions.
Off-road driving involves some new skills. And that is why it is very important that you read this guide. You will find many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable. If you think you will need some more ground clearance at the front of your vehicle, you can remove the front fascia lower air dam. The front fascia lower air dam is held in place by two bolts and 10 snap features.
Loading Your Vehicle for Off-Road Driving {CAUTION: • Cargo on the load floor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. • Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. • Heavy loads on the roof raise the vehicle’s center of gravity, making it more likely to roll over.
Environmental Concerns Traveling to Remote Areas Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. We recognize these concerns and urge every off-roader to follow these basic rules for protecting the environment: • Always use established trails, roads, and areas that have been specially set aside for public off-road recreational driving; obey all posted regulations.
Getting Familiar with Off-Road Driving It is a good idea to practice in an area that is safe and close to home before you go into the wilderness. Off-road driving does require some new and different driving skills. Here is what we mean. Tune your senses to different kinds of signals. Your eyes, for example, need to constantly sweep the terrain for unexpected obstacles. Your ears need to listen for unusual tire or engine sounds.
Scanning the Terrain Off-road driving can take you over many different kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider. Surface Conditions: Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow, or ice. Each of these surfaces affects the steering, acceleration, and braking of your vehicle in different ways.
When you drive over bumps, rocks, or other obstacles, the wheels can leave the ground. If this happens, even with one or two wheels, you cannot control the vehicle as well or at all. Because you will be on an unpaved surface, it is especially important to avoid sudden acceleration, sudden turns, or sudden braking. In a way, off-road driving requires a different kind of alertness from driving on paved roads and highways. There are no road signs, posted speed limits, or signal lights.
Approaching a Hill When you approach a hill, you need to decide if it is one of those hills that is just too steep to climb, descend, or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top. On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs.
Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. • Use a low gear and get a firm grip on the steering wheel. • Get a smooth start up the hill and try to maintain your speed. Do not use more power than you need, because you do not want the wheels to start spinning or sliding. • Try to drive straight up the hill if at all possible. • • • • {CAUTION: Turning or driving across steep hills can be dangerous.
Q: What should I do if my vehicle stalls, or is about to stall, and I cannot make it up the hill? A: If this happens, there are some things you should do, and there are some things you must not do. First, here is what you should do: • Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. • If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R).
Q: Suppose, after stalling, I try to back down the hill and decide I just cannot do it. What should I do? A: Set the parking brake, put your transmission in PARK (P), and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. Do not shift the transfer case to NEUTRAL when you leave the vehicle. Leave it in some gear.
Driving Downhill When off-roading takes you downhill, you will want to consider a number of things: • How steep is the downhill? Will I be able to maintain vehicle control? • What is the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? • Are there hidden surface obstacles? Ruts? Logs? Boulders? • What is at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks? If you decide you can go down a hill safely, then try to keep your vehicle headed straight d
Q: Are there some things I should not do when driving down a hill? A: Yes! These are important because if you ignore them you could lose control and have a serious accident. • When driving downhill, avoid turns that take you across the incline of the hill. A hill that is not too steep to drive down may be too steep to drive across. You could roll over if you do not drive straight down. • Never go downhill with the transmission in NEUTRAL (N). This is called “free-wheeling.
Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: {CAUTION: Driving across an incline that is too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, do not drive across it. Find another route instead.
Q: What if I am driving across an incline that is not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and “walk the course” so you know what the surface is like before you drive it.
Driving in Mud, Sand, Snow, or Ice When you drive in mud, snow, or sand, your wheels will not get good traction. You cannot accelerate as quickly, turning is more difficult, and you will need longer braking distances. If your vehicle has four-wheel drive, see Four-Wheel Drive on page 154 for transfer case mode selection. It is best to use a low gear when you are in mud —the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you do not get stuck.
Driving in Water {CAUTION: Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires, and you could lose traction and roll the vehicle over. Do not drive through rushing water. Heavy rain can mean flash flooding, and flood waters demand extreme caution. Find out how deep the water is before you drive through it.
After Off-Road Driving Remove any brush or debris that has collected on the underbody, chassis, or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires, and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage.
You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to re-adjust to the dark. When you are faced with severe glare, as from a driver who does not lower the high beams, or a vehicle with misaimed headlamps, slow down a little. Avoid staring directly into the approaching headlamps. Driving in Rain and on Wet Roads Keep the windshield and all the glass on your vehicle clean — inside and out.
And, if your tires do not have much tread left, you will get even less traction. It is always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. If your vehicle has four-wheel drive, see Four-Wheel Drive on page 154 for transfer case mode selection. {CAUTION: Wet brakes can cause accidents. They may not work as well in a quick stop and may cause pulling to one side.
Hydroplaning Driving Through Deep Standing Water Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road. Notice: If you drive too quickly through deep puddles or standing water, water can come in through the engine’s air intake and badly damage the engine.
Driving Through Flowing Water Some Other Rainy Weather Tips • Turn on your low-beam headlamps — not just {CAUTION: Flowing or rushing water creates strong forces. If you try to drive through flowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of flowing water can carry away a smaller vehicle. If this happens, you and other vehicle occupants could drown.
City Driving One of the biggest problems with city streets is the amount of traffic on them. You will want to watch out for what the other drivers are doing and pay attention to traffic signals. 416 Here are ways to increase your safety in city driving: • Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. • Try to use the freeways that rim and crisscross most large cities.
Freeway Driving The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic.
Before changing lanes, check your mirrors. Then use your turn signal. Just before you leave the lane, glance quickly over your shoulder to make sure there is not another vehicle in your blind spot. Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit.
Here are some things you can check before a trip: • Windshield Washer Fluid: Is the reservoir full? Are all windows clean inside and outside? • Wiper Blades: Are they in good shape? • Fuel, Engine Oil, Other Fluids: Have you checked all levels? • Lamps: Are they all working? Are the lenses clean? • Tires: They are vitally important to a safe, trouble-free trip.
Hill and Mountain Roads If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable. See Off-Road Driving on page 394 for information about driving off-road. • Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system, and transmission. These parts can work hard on mountain roads.
• Stay in your own lane when driving on two-lane {CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. The brakes will have to do all the work of slowing down. They could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have the engine running and your vehicle in gear when you go downhill. roads in hills or mountains. Do not swing wide or cut across the center of the road.
Winter Driving Here are some tips for winter driving: • Have your vehicle in good shape for winter. • You might want to put winter emergency supplies in your vehicle. Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and reflective warning triangles.
Whatever the condition — smooth ice, packed, blowing, or loose snow — drive with caution. StabiliTrak® improves your ability to accelerate when driving on a slippery road. But you can turn StabiliTrak® off if you ever need to. See StabiliTrak® System on page 385 and If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 426. Even with StabiliTrak®, slow down and adjust your driving to the road conditions.
If You Are Caught in a Blizzard If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: • Turn on the hazard warning flashers. • Tie a red cloth to your vehicle to alert police that you have been stopped by the snow. • Put on extra clothing or wrap a blanket around you.
{CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust pipe. And check around again from time to time to be sure snow does not collect there. Run your engine only as long as you must. This saves fuel.
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow In order to free your vehicle when it is stuck, you need to spin the wheels, but you do not want to spin the wheels too fast. The method known as rocking can help you get out when you are stuck, but you must use caution. {CAUTION: If you let your vehicle’s tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat.
Recovery Hooks (Except SS Model) Notice: SS Models have recovery hooks that are concealed by the front bumper trim covering. Use of the recovery hooks could cause damage to your vehicle. If you have the SS Model, do not use the recovery hooks. {CAUTION: These hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back.
Loading Your Vehicle Tire and Loading Information Label It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on your vehicle show how much weight it was designed to carry, the Tire and Loading Information label and the Certification/Tire label.
The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation see Tires on page 558 and Inflation - Tire Pressure on page 567. There is also important loading information on the vehicle Certification/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles.
Example 1 Item A B C 430 Description Vehicle Capacity Weight for Example 1 = Subtract Occupant Weight 150 lbs (68 kg) × 2 = Available Occupant and Cargo Weight = Example 2 Total Item 1,000 lbs (453 kg) A 300 lbs (136 kg) B 700 lbs (317 kg) C Description Vehicle Capacity Weight for Example 2 = Subtract Occupant Weight 150 lbs (68 kg) × 5 = Available Cargo Weight = Total 1,000 lbs (453 kg) 750 lbs (136 kg) 250 lbs (113 kg)
Certification/Tire Label Example 3 Item A B C Description Vehicle Capacity Weight for Example 3 = Subtract Occupant Weight 200 lbs (91 kg) × 5 = Available Cargo Weight = Total 1,000 lbs (453 kg) 1000 lbs (453 kg) 0 lbs (0 kg) Refer to your vehicle’s tire and loading information label for specific information about your vehicle’s capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s capacity weight.
To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle. The Certification/Tire label also contains important information about your Front Axle Reserve Capacity.
If you put things inside your vehicle — like suitcases, tools, packages, or anything else — they go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going. CAUTION: (Continued) • Do not leave an unsecured child restraint in your vehicle. • When you carry something inside the vehicle, secure it whenever you can. {CAUTION: • Do not leave a seat folded down unless you need to.
Two-Tiered Loading Add-On Equipment Depending on the model of your pick-up, you can create an upper load platform by positioning two or four 2 inches (5 cm) by 6 inches (15 cm) wooden planks across the width of the pickup box. The planks must be inserted in the pickup box depressions. The length of the planks must allow for at least a 3/4 inch (2 cm) bearing surface on each end of the plank. When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle.
Adding a Snow Plow or Similar Equipment Before installing a snow plow on your vehicle, here are some things you will need to know: Notice: If your vehicle does not have the snow plow prep package, adding a plow can damage your vehicle, and the repairs would not be covered by warranty. Unless your vehicle was built to carry a snow plow, do not add one to your vehicle.
Say, for example, you have a 700 lb (318 kg) snow plow. The total weight of all occupants and cargo inside the cab should not exceed 300 lb (135 kg). This means that you may only be able to carry one passenger. But, even this may be too much if you have got other equipment already adding to the weight of your vehicle. Here are some guidelines for safely carrying a snow plow on your vehicle: • Make sure the weight on the front and rear axles does not exceed the axle rating for each.
The front axle reserve capacity for your vehicle can be found in the lower right corner of the Certification/Tire label, as shown. United States Canada In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula: (W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle. Where: W = Weight of added accessory A = Distance that the accessory is in front of the front axle W.B.
For example, adding a 700 lb (318 kg) snow plow actually adds more than 700 lbs (318 kg) to the front axle. Using the formula, if the snow plow is 4 ft (122 cm) in front of the front axle and the wheel base is 10 ft (305 cm), then: W = 700 lb (318 kg) A = 4 ft (122 cm) W.B. = 10 ft (305 cm) (W x (A + W.B.))/W.B. = (700 x (4 + 10))/10 = 980 lbs (445 kg) So, if your truck’s front axle reserve capacity is more than 980 lbs (445 kg), you could add the snow plow without exceeding the front GAWR.
Q: What is total vehicle reserve capacity? A: This is the difference between your GVWR and the weight of your truck with full fuel and passengers. It is the amount of weight you can add to your vehicle before reaching your GVWR. Keep in mind that reserve capacity numbers are intended as a guide when selecting the amount of equipment or cargo your truck can carry. If you are unsure of your vehicle’s front, rear, or total weight, go to a weigh station and weigh your vehicle.
When you carry a slide-in camper, the total cargo load of your vehicle is the weight of the camper, plus the following: • Everything else added to the camper after it left the factory • Everything in the camper • All the people inside The Cargo Weight Rating (CWR) is the maximum weight of the load your vehicle can carry. It does not include the weight of the people inside. But, you can figure about 150 lbs (68 kg) for each seat. The total cargo load must not be more than your vehicle’s CWR.
Here is an example of proper truck and camper match: The total cargo load should not exceed the truck’s cargo weight rating and the camper’s center of gravity (A) should fall within the truck’s recommended center of gravity zone (B) when installed. You must weigh any accessories or other equipment that you add to your vehicle. Then, subtract this extra weight from the CWR. This extra weight may shorten the center of gravity zone of your vehicle. Your dealer can help you with this. A.
After you have loaded your vehicle and camper, drive to a weigh station and weigh the front and rear wheels separately. This will tell you the loads on the axles. The loads on the front and rear axles should not be more than either of the Gross Axle Weight Ratings (GAWR). The total of the axle loads should not be more than the Gross Vehicle Weight Rating (GVWR). The total of the axle loads should not exceed your vehicle’s gross vehicle weight rating (GVWR).
Pickup Conversion to Chassis Cab Recreational Vehicle Towing We are aware that some vehicle owners might consider having the pickup box removed and a commercial or recreational body installed. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which could affect vehicle safety. The components necessary to adapt a pickup to permit its safe use with a specialized body should be installed by the body builder.
Here are some important things to consider before you do recreational vehicle towing: • What’s the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer’s recommendations. • How far will you tow? Some vehicles have restrictions on how far and how long they can tow. • Do you have the proper towing equipment? See your dealer or trailering professional for additional advice and equipment recommendations.
Four-Wheel-Drive Vehicles {CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. Use the following procedure to tow your vehicle: 1. Shift the transmission to PARK (P). 2. Turn the engine off, but leave the ignition on. 3. Firmly set the parking brake. 4.
Dolly Towing Four-Wheel-Drive Vehicles Front Towing (Front Wheels Off the Ground) Two-Wheel-Drive Vehicles Notice: If you tow a two-wheel-drive vehicle with the rear wheels on the ground, the transmission could be damaged. The repairs would not be covered by your warranty. Never tow your vehicle with the rear wheels on the ground. Two-wheel-drive vehicles should not be towed with the rear wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed.
{CAUTION: Rear Towing (Rear Wheels Off the Ground) Two-Wheel-Drive Vehicles Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. 6. Shift the transfer case to NEUTRAL. See Four-Wheel Drive on page 154 for the proper procedure to select the neutral position for your vehicle. 7.
Four-Wheel-Drive Vehicles Use the following procedure to tow your vehicle from the rear: 1. Drive the vehicle onto the dolly. 2. Firmly set the parking brake. See Parking Brake on page 169. 3. Put the transmission in PARK (P). 4. Follow the dolly manufacturer’s instructions to attach and secure the vehicle being towed to the dolly and then the loaded dolly to the tow vehicle. Use an adequate clamping device to ensure that the front wheels are locked into the straight position.
Towing a Trailer If your vehicle has a diesel engine, see the DURAMAX® Diesel manual for more information. Do not tow a trailer during break-in. See New Vehicle Break-In on page 139 for more information. {CAUTION: If you do not use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well — or even at all. You and your passengers could be seriously injured.
If You Do Decide To Pull A Trailer If you do, here are some important points: • There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. • Consider using a sway control. See “Hitches” later in this section. • Don’t tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven.
Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75 percent of the vehicle’s Gross Combined Weight Rating (GCWR). See “Weight of the Trailer” later in the section. Tow/Haul is most useful under the following driving conditions: • When pulling a heavy trailer or a large or heavy load through rolling terrain. • When pulling a heavy trailer or a large or heavy load in stop and go traffic.

Fifth wheel or gooseneck kingpin weight should be 15 to 25 percent of the trailer weight up to the maximum amount specified in the trailering chart for your vehicle. See “Weight of the Trailer”, and “Fifth-Wheel and Gooseneck Trailering” in this section.
Consider the following example: A vehicle model base weight is 5,500 lbs (2 495 kg); 2,800 lbs (1 270 kg) at the front axle and 2,700 lbs (1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs (3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a GCWR (Gross Combination Weight Rating) of 14,000 lbs (6 350 kg).
But, you must still consider the effect on the rear axle. Because your rear axle now weighs 3,100 lbs (1 406 kg), you can only put 900 lbs (408 kg) on the rear axle without exceeding RGAWR. The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you with being able to handle only 600 lbs (272 kg) of tongue weight.
Weight-Distributing Hitches and Weight Carrying Hitches If you use a step-bumper hitch, the bumper could be damaged in sharp turns. Make sure there is ample room when turning to avoid contact between the trailer and the bumper. If you will be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when driving.
The hitch should be located in the pickup bed so that it’s centerline is over or slightly in front of the rear axle. Take care that it is not so far forward that it will contact the back of the cab in sharp turns. This is especially important for short box pickups. Trailer pin box extensions and sliding fifth wheel hitch assemblies can help this condition. There should be at least six inches of clearance between the top of the pickup box and the bottom of the trailer shelf that extends over the box.
Your trailer brake system can tap into the vehicle’s hydraulic brake system only if: • The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. • The trailer’s brake system will use less than 0.02 cubic inch (0.3 cc) of fluid from your vehicle’s master cylinder. Otherwise, both braking systems won’t work well. You could even lose your brakes. If everything checks out this far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes.
The ITBC system is powered through your vehicle’s electrical system. Turning the ignition off will also turn off the ITBC system. The ITBC system is fully functional only when the ignition is in ON or in RUN. The ITBC system can only be used with trailers with electric brakes. {CAUTION: Connecting a trailer that is not compatible with the ITBC system may result in reduced or complete loss of trailer braking.
Trailer Brake Control Panel A. Manual Trailer Brake Apply Lever B. Trailer Gain Adjustment Buttons 474 The ITBC system has a control panel located on the instrument panel to the left of the steering column. See Instrument Panel Overview (Base/Uplevel version) on page 212 or Instrument Panel Overview (Premium version) on page 215 for more information on location.
Trailer Brake DIC Display Page The ITBC system displays messages into the vehicle’s Driver Information Center (DIC). See DIC Warnings and Messages on page 285 for more information. The display page indicates Trailer Gain setting, power output to the electric trailer brakes, trailer connection and system operational status.
TRAILER GAIN – This setting is displayed anytime the Trailer Brake Display Page is active. This setting can be adjusted from 0.0 to 10.0 with either a trailer connected or disconnected. To adjust the Trailer Gain, press one of the Trailer Gain adjustment buttons located on the Trailer Brake Control Panel. Press and hold a gain button to cause the Trailer Gain to continuously adjust. To turn the output to the trailer off, adjust the Trailer Gain setting to 0.0 (zero). 0.
Manual Trailer Brake Apply Trailer Gain Adjustment Procedure The Manual Trailer Brake Apply Lever is located on the Trailer Brake Control Panel and is used to apply the trailer’s electric brakes independent of your vehicle’s brakes. This lever is used in the Trailer Gain Adjustment Procedure to properly adjust the power output to the trailer brakes. Sliding the lever to the left will apply only the trailer brakes. The power output to the trailer is indicated in the Trailer Brake Display Page in the DIC.
3. After the electrical connection is made to a trailer equipped with electric brakes: • A TRAILER CONNECTED message will be briefly displayed on the DIC display. • The Trailer Brake Display Page will appear on the DIC showing TRAILER GAIN and TRAILER OUTPUT. • In the Trailer Output display on the DIC, “- - - - - -“ will disappear if there is no error present. Connecting a trailer without electric brakes will not clear the six dashed lines. 4.
Other ITBC Related DIC Messages In addition to displaying TRAILER GAIN and TRAILER OUTPUT through the DIC, trailer connection and ITBC system status is displayed in the DIC. TRAILER CONNECTED – This message will be briefly displayed when a trailer with electric brakes is first connected to the vehicle. This message will automatically turn off in about ten seconds. The driver can also acknowledge this message before it automatically turns off. CHECK TRAILER WIRING – This message will be displayed if: 1.
To determine if the electrical fault is on the vehicle side or trailer side of the trailer wiring harness connection, do the following: 1. Disconnect the trailer wiring harness from the vehicle. 2. Turn the ignition OFF. 3. Wait ten seconds, then turn the ignition back to RUN. 4. If the CHECK TRAILER WIRING message re-appears, the electrical fault is on the vehicle side.
Driving with a Trailer CAUTION: {CAUTION: (Continued) • If exhaust does come into your vehicle If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You cannot see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 173. To maximize your safety when towing a trailer: • Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip.
Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.
Turn Signals When Towing a Trailer The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not.
Parking on Hills {CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet. 2. Have someone place chocks under the trailer wheels. 484 3.
{CAUTION: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, use the steps that follow. Always put the shift lever fully in PARK (P) with the parking brake firmly set. When You Are Ready to Leave After Parking on a Hill 1.
Maintenance When Trailer Towing Basic Trailer Wiring Your vehicle will need service more often when you’re pulling a trailer. See Scheduled Maintenance (Gasoline Engine) on page 633 for more information. Things that are especially important in trailer operation are automatic transmission fluid (don’t overfill), engine oil, axle lubricant, belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly.
Heavy-DutyTrailer Wiring Harness Package For vehicles equipped with heavy duty trailering, the harness is connected to a bracket on the hitch platform. The seven-wire harness contains the following trailer circuits: • Yellow: Left Stop/Turn Signal • • • • • • *The fuses for these two circuits are installed in the underhood electrical center, but the wires are not connected. They should be connected by your dealer or a qualified service center.
Camper/Fifth-Wheel Trailer Wiring Package The seven-wire camper harness is located under the front edge of the pickup box on the driver’s side of the vehicle, attached to the frame bracket. A connector will have to be added to the wiring harness which connects to the camper.
Electric Brake Control Wiring Provisions These wiring provisions are included with your vehicle as part of the trailer wiring package. These provisions are for an electric brake controller. The instrument panel contains blunt cut wires near the data link connector for the trailer brake controller.
Be sure to follow the proper installation instructions that are included with any electrical equipment that you install. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not use equipment that exceeds the maximum amperage rating for the auxiliary battery provision. Power Winches If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored.

California Proposition 65 Warning Most motor vehicles, including this one, contain and/or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Engine exhaust, many parts and systems (including some inside the vehicle), many fluids, and some component wear by-products contain and/or emit these chemicals.
Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle. Fuel If your vehicle has a diesel engine, see “Diesel Fuel Requirements and Fuel System” in the DURAMAX® Diesel Supplement. For vehicles with gasoline engines, please read this.
Gasoline Octane California Fuel Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you might notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service.
Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations.
Fuel E85 (85% Ethanol) The 8th digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies your vehicle’s engine. The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 616. If your vehicle has the 5.3L V8 engine (VIN Code 0) or the 5.3L V8 engine (VIN Code 3), you can use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel on page 496.
E85 has less energy per gallon than gasoline, so you will need to refill the fuel tank more often when using E85 than when you are using gasoline. See Filling the Tank on page 500. Notice: Some additives are not compatible with E85 fuel and can harm your vehicle’s fuel system. Do not add anything to E85. Damage caused by additives would not be covered by your new vehicle warranty. Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol.
{CAUTION: Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way. The tethered fuel cap is located behind a hinged fuel door on the driver’s side of the vehicle.
When replacing the fuel cap, turn it clockwise until it clicks. It will require more effort to turn the fuel cap on the last turn as you tighten it. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 266. The TIGHTEN GAS CAP message will be displayed on the Driver Information Center (DIC) if the fuel cap is not properly installed.
Filling a Portable Fuel Container CAUTION: (Continued) • Bring the fill nozzle in contact with the {CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: • Dispense gasoline only into approved containers.
Checking Things Under the Hood {CAUTION: An electric engine cooling fan can start even when the engine is not running. To avoid injury, always keep hands, clothing, and tools away from any engine cooling fan. {CAUTION: Things that burn can get on hot engine parts and start a fire. These include liquids like fuel, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine.
2. Then go to the front of the vehicle and locate the secondary hood release. This is located under the hood, near the center of the grille. 3. Push the secondary hood release to the right. 4. Lift the hood. Before closing the hood, be sure all the filler caps are on properly. Then bring the hood from full open to within 6 inches (152 mm) from the closed position, pause, then push the front center of the hood with a swift, firm motion to fully close the hood.
Engine Compartment Overview If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. When you open the hood on the 5.3L engine (4.3L, 4.8L and 6.

Engine Oil (Gasoline Engine) Checking Engine Oil If your vehicle has a diesel engine, see “Engine Oil” in the DURAMAX® Diesel Engine Supplement. It is a good idea to check the engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. If the CHECK OIL LEVEL light appears on the instrument cluster, except vehicles that have the 4.3L engine, check the engine oil level right away.
When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, you need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 626. See Engine Compartment Overview on page 506 for the location of the engine oil fill cap. Be sure to add enough oil to put the level somewhere in the proper operating range.
What Kind of Engine Oil to Use Look for three things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. Look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. 510 These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. • Oils meeting these requirements should have the starburst symbol on the container.
If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both provide easier cold starting and better protection for the engine at extremely low temperatures. Engine Oil Additives Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you need for good performance and engine protection.
How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change the oil prior to a CHANGE ENGINE OIL SOON message coming on, reset the system. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the Engine Oil Life System: 1.
Engine Air Cleaner/Filter (Gasoline Engines) When to Inspect the Engine Air Cleaner/Filter If your vehicle has a diesel engine, see “Pickup Models” under “Engine Air Cleaner/Filter” in the DURAMAX® Diesel Supplement for the correct inspection and replacement procedures. If your vehicle has an air filter restriction indicator, it lets you know when the engine air cleaner/filter needs to be replaced.
How to Inspect the Engine Air Cleaner/Filter Vehicles With an Air Filter Restriction Indicator Replacing the Engine Air Cleaner/Filter and Resetting the Air Filter Restriction Indicator Locate the air filter restriction indicator on the engine air cleaner/filter cover. When the indicator turns black or is in the red/orange “change” zone, replace the filter and reset the indicator. See Steps 1 through 7 to replace the engine air cleaner/filter and to reset the air filter restriction indicator.
{CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off. 3. Remove the engine air cleaner/filter from the housing. Care should be taken to dislodge as little dirt as possible. 4.
Automatic Transmission Fluid When to Check and Change Automatic Transmission Fluid It is usually not necessary to check the transmission fluid level. The only reason for fluid loss is a transmission leak or overheating the transmission. If you suspect a small leak, then use the following checking procedures to check the fluid level.
3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, move the shift lever back to PARK (P). 4. Allow the engine to idle (500 – 800 rpm) for at least one minute. Slowly release the brake pedal. 5. Keep the engine running and press the Trip/Fuel button or trip odometer reset stem until TRANS TEMP (Transmission Temperature) displays on the Driver Information Center (DIC). 6.
3. Install the dipstick by pushing it back in all the way, wait three seconds, and then pull it back out again. 4. Check both sides of the dipstick, and read the lower level. Repeat the check procedure to verify the reading. 6. Perform a hot check at the first opportunity after the transmission reaches a normal operating temperature between 160°F to 200°F (71°C to 93°C). 7.
The dipstick handle has this graphic. See Engine Compartment Overview on page 506 for more information. 2. Flip the handle up, and then pull out the dipstick and wipe it with a clean rag or paper towel. 3. Install the dipstick by pushing it back in all the way, wait three seconds, and then pull it back out again. 4. Check both sides of the dipstick, and read the lower level. Repeat the check procedure to verify the reading. 5. Safe operating level is within the HOT crosshatch band on the dipstick.
Consistency of Readings Always check the fluid level at least twice using the procedures described. Consistency (repeatable readings) is important to maintaining proper fluid level. If fluid is added, it may take 15 minutes or longer to obtain an accurate reading because of residual fluid draining down the dipstick tube. If inconsistent readings persist, check the transmission breather to be sure it is clean and not clogged. If readings are still inconsistent, contact your dealer/retailer.
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant which will not damage aluminum parts. If you use this coolant mixture, you do not need to add anything else. {CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant Adding Coolant The coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 506 for more information on location. If you need more coolant, add the proper DEX-COOL® coolant mixture at the surge tank, but only when the engine is cool. See Cooling System on page 527 for more information.
Coolant Surge Tank Pressure Cap Engine Overheating Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. The coolant surge tank pressure cap must be fully installed on the coolant surge tank. See Engine Compartment Overview on page 506 for more information on location.
If Steam Is Coming From Your Engine CAUTION: {CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when the vehicles engine is overheated, the liquids in it can catch fire. You or others could be badly burned.
If No Steam Is Coming From Your Engine The ENGINE OVERHEATED STOP ENGINE or the ENGINE OVERHEATED IDLE ENGINE message, along with a low coolant condition, can indicate a serious problem. If you get an engine overheat warning, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: • Climb a long hill on a hot day. • Stop after high-speed driving. • Idle for long periods in traffic. • Tow a trailer. See Towing a Trailer on page 449.
If the warning continues, pull over, stop, and park your vehicle immediately. If there is still no sign of steam and your vehicle has an engine-driven cooling fan, push down the accelerator until the engine speed is about twice as fast as normal idle speed for at least five minutes while you are parked. If there is still no sign of steam and your vehicle has an electric cooling fan, idle the engine for five minutes while you are parked.
Cooling System If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. When you decide it is safe to lift the hood, here is what you will see: {CAUTION: An electric engine cooling fan can start even when the engine is not running. To avoid injury, always keep hands, clothing, and tools away from any engine cooling fan. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down.
{CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. The coolant level should be at or above the FULL COLD mark.
Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX-COOL® (silicate-free) coolant in your vehicle.
{CAUTION: {CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and a proper coolant.
2. Then keep turning the pressure cap slowly, and remove it. 4. With the coolant surge tank pressure cap off, start the engine and let it run until the engine coolant temperature gage indicates approximately 195°F (90°C). By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark. 5. Then replace the pressure cap.
Engine Fan Noise If your vehicle has a clutched engine cooling fan, when the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, so you may hear an increase in fan noise.
When to Check Power Steering Fluid What to Use It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 644. Always use the proper fluid. How to Check Power Steering Fluid To check the power steering fluid, do the following: 1.
Adding Washer Fluid Your vehicle has a low washer fluid message in the DIC that comes on when the washer fluid is low. The message is displayed for 15 seconds at the start of each ignition cycle. When the WASHER FLUID LOW ADD FLUID message displays, you will need to add washer fluid to the windshield washer fluid reservoir. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 506 for reservoir location.
Brakes Brake Fluid The brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 506 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system.
Checking Brake Fluid What to Add The brake fluid can be checked without taking off the cap by looking at the brake fluid reservoir. When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See Recommended Fluids and Lubricants on page 644. The fluid level should be above MIN. If it is not, have the brake system checked to see if there is a leak. Always clean the brake fluid reservoir cap and the area around the cap before removing it.
Notice: • Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake system can damage brake system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid. • If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See Washing Your Vehicle on page 611.
If you have rear drum brakes, they do not have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected immediately. Rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. Drum brakes have an inspection hole to inspect lining wear during scheduled maintenance. When you have the front brake pads replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets.
Battery Vehicle Storage Your vehicle has a maintenance free battery (or batteries). When it is time for a new battery, see your dealer/retailer for one that has the replacement number shown on the original battery’s label. See Engine Compartment Overview on page 506 for battery location. Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
Jump Starting If your vehicle’s battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. {CAUTION: Batteries can hurt you. They can be dangerous because: • They contain acid that can burn you. • They contain gas that can explode or ignite. • They contain enough electricity to burn you. If you do not follow these steps exactly, some or all of these things can hurt you.
3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause an unwanted ground connection. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure.
{CAUTION: An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. The remote negative (−) terminal is a stud located on the right front passenger side of the engine, where the negative battery cable attaches.
{CAUTION: {CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there.
7. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. 5.3L engine (4.3L, 4.8L and 6.0L similar) 8. Do not let the other end touch metal.

Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle. 3. Install the new blade onto the arm connector and make sure the grooved areas are fully set in the locked position. For the proper type and size, see Normal Maintenance Replacement Parts on page 646.
20-Inch Tires CAUTION: (Continued) • Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your vehicle’s tires are cold. See Inflation - Tire Pressure on page 567. • Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure.
Tire Sidewall Labeling Useful information about a tire is molded into the sidewall. The following illustrations are examples of a typical P-Metric and a LT-Metric tire sidewall. (A) Tire Size: The tire size code is a combination of letters and numbers used to define a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section for more detail.
(E) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction, and temperature resistance. For more information, see Uniform Tire Quality Grading on page 581. (G) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load.
(B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines. (C) Dual Tire Maximum Load: Maximum load that can be carried and the maximum pressure needed to support that load when used in a dual configuration.
Tire Size The following examples show the different parts of a tire size. (A) Light Truck (LT-Metric) Tire: The United States version of a metric tire sizing system. The letters LT as the first two characters in the tire size means a light truck tire engineered to standards set by the U.S. Tire and Rim Association. (B) Tire Width: The three-digit number indicates the tire section width in millimeters from sidewall to sidewall.
(E) Rim Diameter: Diameter of the wheel in inches. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. (F) Service Description: The service description indicates the load range and speed rating of a tire. The load index can range from 1 to 279. Speed ratings range from A to Z. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread.
GAWR FRT: Gross Axle Weight Rating for the front axle. See Loading Your Vehicle on page 428. GAWR RR: Gross Axle Weight Rating for the rear axle. See Loading Your Vehicle on page 428. Intended Outboard Sidewall: The side of an asymmetrical tire, that must always face outward when mounted on a vehicle. Kilopascal (kPa): The metric unit for air pressure. Light Truck (LT-Metric) Tire: A tire used on light duty trucks and some multipurpose passenger vehicles.
Recommended Inflation Pressure: Vehicle manufacturer’s recommended tire inflation pressure as shown on the tire placard. See Inflation - Tire Pressure on page 567 and Loading Your Vehicle on page 428. Radial Ply Tire: A pneumatic tire in which the ply cords that extend to the beads are laid at 90 degrees to the centerline of the tread. Rim: A metal support for a tire and upon which the tire beads are seated. Sidewall: The portion of a tire between the tread and the bead.
Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not.
How to Check Dual Tire Operation Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).
{CAUTION: If you operate your vehicle with a tire that is badly underinflated, the tire can overheat. An overheated tire can lose air suddenly or catch fire. You or others could be injured. Be sure all tires (including the spare) are properly inflated. See Inflation - Tire Pressure on page 567, for information on proper tire inflation. Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels.
You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the CHECK TIRE PRESSURE message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
Resetting the TPMS Identification Codes Each TPMS sensor has a unique identification code. Any time you rotate your vehicle’s tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver’s side front tire, passengers side front tire, passengers side rear tire, and driver’s side rear tire using a TPMS diagnostic tool. See your GM dealer for service.
5. Start with the driver’s side front tire. 6. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which make take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. To decrease air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. 9.
Federal Communications Commission (FCC) and Industry and Science Canada Tire Inspection and Rotation The Tire Pressure Monitor System (TPMS) operates on a radio frequency and complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation.
If your vehicle has single rear wheels and the tread design for your front tires is the same as your rear tires, use the rotation pattern shown here when rotating your tires. If your vehicle has dual rear wheels and the tread design for your front tires is the same as your rear tires, always use one of the correct rotation patterns shown here when rotating your tires.
If your vehicle has dual rear wheels and the tread design for the front tires is different from the dual rear tires, always use the correct rotation pattern shown here when rotating your tires. The dual tires are rotated as a pair, and the inside rear tires become the outside rear tires. When you install dual wheels, be sure the vent holes in the inner and outer wheels on each side are lined up.
When It Is Time for New Tires One way to tell when it is time for new tires is to check the treadwear indicators, which appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire’s rubber.
Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating.
{CAUTION: If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires.
Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this could affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover. Additionally, if your vehicle has electronic systems such as anti-lock brakes, rollover airbags, traction control, and electronic stability control, the performance of these systems can be affected.
Uniform Tire Quality Grading Treadwear Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100.
Temperature – A, B, C Wheel Alignment and Tire Balance The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.
Used Replacement Wheels CAUTION: {CAUTION: Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Tire Chains {CAUTION: If your vehicle has dual wheels or P265/65R18, P275/55R20 or LT265/70R17 size tires, do not use tire chains.
Notice: If your vehicle does not have dual wheels and has a tire size other than P265/65R18, P275/55R20 or LT265/70R17, use tire chains only where legal and only when you must. Use chains that are the proper size for your tires. Install them on the tires of the rear axle. Do not use chains on the tires of the front axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions.
A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid. In any rear blowout remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible.
CAUTION: (Continued) 3. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear – not in NEUTRAL. 4. Turn off the engine and do not restart while the vehicle is raised. 5. Do not allow passengers to remain in the vehicle. To be even more certain the vehicle will not move, put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side, at the opposite end of the vehicle.

For more information, refer to Removing the Spare Tire and Tools on page 588 for more information.
Do not mix tires and wheels of different sizes, because they will not fit. Keep your spare tire and its wheel together. If your vehicle has a spare tire that does not match your vehicle’s original road tires and wheels in size and type, do not include the spare in the tire rotation. Appearance Care Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery.
Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your GM dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your GM dealer to remove odors from your vehicle’s upholstery. Do not clean your vehicle using the following cleaners or techniques: • Never use a knife or any other sharp object to remove a soil from any interior surface. • Never use a stiff brush.
To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with water or club soda. 2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 4. Continue to gently rub the soiled area until the cleaning cloth remains clean. 5.
Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended.
Washing Your Vehicle Cleaning Exterior Lamps/Lenses The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 611. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap.
Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years.
Aluminum or Chrome-Plated Wheels and Trim Your vehicle may have either aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Chrome wheels and other chrome trim may be damaged if you do not wash your vehicle after driving on roads that have been sprayed with magnesium, calcium or sodium chloride.
Tires Finish Damage To clean the tires, use a stiff brush with tire cleaner. Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle.
Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface.

Maintenance Schedule Introduction This maintenance section applies to vehicles with a gasoline engine. If your vehicle has a diesel engine, see the maintenance schedule section in the DURAMAX® Diesel Engine Supplement. Important: Keep engine oil at the proper level and change as recommended.
Using the Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary.
{CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualified technician do the work. See Doing Your Own Service Work on page 495. Some maintenance services can be complex.

Customer Assistance and Information Customer Satisfaction Procedure Your satisfaction and goodwill are important to your dealer and to Chevrolet. Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur.
STEP THREE — U.S. Owners: Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps 1 and 2, you should file with the Better Business Bureau (BBB) Auto Line Program to enforce your rights.
STEP THREE — Canadian Owners: In the event that you do not feel your concerns have been addressed after following the procedure outlined in Steps 1 and 2, General Motors of Canada Limited wants you to be aware of its participation in a no-charge Mediation/Arbitration Program. General Motors of Canada Limited has committed to binding arbitration of owner disputes involving factory-related vehicle service claims.

Customer Assistance for Text Telephone (TTY) Users To assist customers who are deaf, hard of hearing, or speech-impaired and who use Text Telephones (TTYs), Chevrolet has TTY equipment available at its Customer Assistance Center. Any TTY user in the U.S. can communicate with Chevrolet by dialing: 1-800-833-CHEV (2438). (TTY users in Canada can dial 1-800-263-3830.) Customer Assistance Offices Chevrolet encourages customers to call the toll-free number for assistance.
Overseas — Customer Assistance Please contact the local General Motors Business Unit. GM Mobility Reimbursement Program Mexico, Central America and Caribbean Islands/Countries (Except Puerto Rico and U.S. Virgin Islands) — Customer Assistance General Motors de Mexico, S. de R.L. de C.V. Customer Assistance Center Paseo de la Reforma # 2740 Col. Lomas de Bezares C.P. 11910, Mexico, D.F.
Roadside Assistance Program Services Provided For vehicles purchased in the U.S., call 1-800-CHEV-USA (1-800-243-8872); (Text telephone (TTY): 1-888-889-2438). The following services are provided in the U.S. and Canada up to 5 years/100,000 miles (160 000 km), whichever occurs first, and, in Canada only, up to a maximum coverage of $100. • Fuel Delivery: Delivery of enough fuel for the vehicle to get to the nearest service station (approximately $5 in Canada).
• Emergency Tow From a Public Roadway or Highway: Tow to the nearest dealership for warranty service or in the event of a vehicle-disabling accident. Winch-out assistance is provided when the vehicle is mired in sand, mud, or snow. • Flat Tire Change: Installation of a spare tire in good condition, when equipped and properly inflated, is covered at no charge. The customer is responsible for the repair or replacement of the tire if not covered by a warrantable failure.
• Alternative Service (Canada only): There may be times, when Roadside Assistance cannot provide timely assistance. Your advisor may authorize you to secure local emergency road service, and you will be reimbursed up to $100 upon submission of the original receipt to Roadside Assistance. In many instances, mechanical failures may be covered. However, any cost for parts and labor for non-warranty repairs are the responsibility of the driver.
Towing and Road Service Exclusions Courtesy Transportation Specifically excluded from Roadside Assistance coverage are towing or services for vehicles operated on a non-public roadway or highway, fines, impound towing caused by a violation of local, Municipal, State, Provincial, or Federal law, and mounting, dismounting or changing of snow tires, chains, or other traction devices.
Scheduling Service Appointments Transportation Options When your vehicle requires warranty service, contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. Warranty service can generally be completed while you wait. However, if you are unable to wait, GM helps to minimize your inconvenience by providing several transportation options.
Public Transportation or Fuel Reimbursement If your vehicle requires overnight warranty repairs, and public transportation is used as “shuttle service”, the reimbursement is limited to the associated shuttle allowance and must be supported by original receipts. In addition, for U.S. customers, should you arrange transportation through a friend or relative, limited reimbursement for reasonable fuel expenses may be available. Claim amounts should reflect actual costs and be supported by original receipts.
Collision Damage Repair If your vehicle is involved in a collision and it is damaged, have the damage repaired by a qualified technician using the proper equipment and quality replacement parts. Poorly performed collision repairs diminish your vehicle’s resale value, and safety performance can be compromised in subsequent collisions. Collision Parts Genuine GM Collision parts are new parts made with the same materials and construction methods as the parts with which your vehicle was originally built.
Insuring Your Vehicle If an Accident Occurs Protect your investment in your GM vehicle with comprehensive and collision insurance coverage. There are significant differences in the quality of coverage afforded by various insurance policy terms. Many insurance policies provide reduced protection to your GM vehicle by limiting compensation for damage repairs by using aftermarket collision parts. Some insurance companies will not specify aftermarket collision parts.
• If your vehicle cannot be driven, know where • If possible, call your insurance company the towing service will be taking it. Get a card from the tow truck operator or write down the driver’s name, the service’s name, and the phone number. • Remove any valuables from your vehicle before it is towed away. Make sure this includes your insurance information and registration if you keep these items in your vehicle. • Gather the important information you will need from the other driver.
Managing the Vehicle Damage Repair Process In the event that your vehicle requires damage repairs, GM recommends that you take an active role in its repair. If you have a pre-determined repair facility of choice, take your vehicle there, or have it towed there. Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by your GM vehicle warranty.
