Head Restraints The front seats have adjustable head restraints in the outboard seating positions. { CAUTION: With head restraints that are not installed and adjusted properly, there is a greater chance that occupants will suffer a neck/spinal injury in a crash. Do not drive until the head restraints for all occupants are installed and adjusted properly. Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head.
Front Seats Manual Seats { CAUTION: Pull the head restraint up to raise it. To lower the head restraint, press the button, located on the top of the seatback, and push the restraint down. Push down on the head restraint after the button is released to make sure that it is locked in place. The head restraints are not designed to be removed. The rear seat has head rests that can be adjusted up and down.
If the vehicle has a manual seat, it can be moved forward or rearward. Power Seats 1. Lift the bar to unlock the seat. 2. Slide the seat to the desired position and release the bar. Try to move the seat with your body to be sure the seat is locked in place. 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.
Move the seat forward or rearward by sliding the control forward or rearward. Manual Lumbar Your vehicle may have additional features to adjust your vehicle’s power seat: • Raise or lower the front part of the seat cushion by moving the front of the control up or down. • Raise or lower the rear part of the seat cushion by moving the rear of the control up or down. • Raise or lower the entire seat by moving the entire control up or down.
Power Lumbar The vehicle may have additional features to adjust your vehicle’s power seat: • To raise the height of the lumbar support, press and hold the top of the control. • To lower the height of the lumbar support, press and hold the bottom 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.
Heated Seats Memory Seat, Mirrors, and Pedals On vehicles with heated front seats, the controls are located on the driver and passenger doors. Your vehicle may have the memory package. I (Heated Seatback): Press to turn on the heated seatback. J (Heated Seat and Seatback): Press to turn on the heated seat and seatback. The light on the button will come on to indicate that the feature is working.
To save seating positions in memory: 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. See Outside Power Mirrors on page 2-59 and Adjustable Throttle and Brake Pedal on page 2-26 for more information. Not all mirrors, adjustable throttles and brake pedals, or power lumbar will have the ability to save and recall their positions. 2.
Easy Exit Seat The control for this feature is located on the driver’s door panel between buttons 1 and 2. With the vehicle in PARK (P), the driver’s seat exit position can be recalled by pressing the exit button. You will hear a single beep, and the driver’s seat will move back. If the easy exit seat feature is programmed in the Driver Information Center (DIC), automatic seat movement will occur when the key is removed from the ignition.
{ 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.
Manual Reclining Seatbacks On seats with manual reclining seatbacks, the lever used to operate them is located on the outboard side of the seat(s). To recline the seatback: 1. Lift the recline lever. 2. Move the seatback to the desired position, then release the lever to lock the seatback in place. 3. Push and pull on the seatback to make sure it is locked. To return the seatback to an upright position, do the following: 1.
Power Reclining Seatbacks Seatback Latches The front seatbacks tilt forward to allow access to the rear of the cab. To tilt the seatback forward, lift the lever located on the outboard side of the seat cushion. { CAUTION: If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked.
Rear Seats Rear Seat Operation (Extended Cab 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. 1-14 2.
Rear Seat Operation (All Split Bench and Hybrid Full 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. To return the seat to the normal seating position, slowly pull the seat cushion down.
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. People riding on the tailgate (if equipped) can easily lose their balance and fall even when the vehicle is operated at low speeds. Falling from a moving vehicle may result in serious injuries or death. { CAUTION: Do not let anyone ride where a safety belt cannot be worn properly.
Your vehicle has indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 3-36. In most states and in all Canadian provinces, the law requires wearing safety belts. Here is why: Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. 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 serious one. A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive.
Put someone on it. 1-18 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 a crash if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle a safety belt, even if you are upside down.
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 a crash — even one that is not your fault — you and your passenger(s) 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). Safety belts are for everyone.
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 on your abdomen. This could cause serious or even fatal injuries. 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 shoulder belt locks if there is a sudden stop or crash. Sit up straight and always keep your feet on the floor in front of you.
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 snugly against your body. A: The shoulder belt is too loose. It will not give 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 on 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 on 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 buckle.
Q: What is wrong with this? { CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied on the abdomen, not on the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. A: The belt is over an armrest.
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. The shoulder belt should go over the shoulder and across the chest. A: The shoulder belt is worn under the arm.
Q: What is wrong with this? { CAUTION: You can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, you would not be restrained by the shoulder belt. Your body could move too far forward increasing the chance of head and neck injury. You might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest. A: The belt is behind the body.
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.
Lap-Shoulder Belt If your vehicle is a regular cab, then all seating positions in the vehicle have a lap-shoulder belt. If your vehicle is a crew or extended cab, then all seating positions in the vehicle have a lap-shoulder belt except for the center front passenger position (if equipped), which has a lap belt. See Lap Belt (Crew and Extended Cab) on page 1-36 for more information. The following instructions explain how to wear a lap-shoulder belt properly. 1.
3. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 1-37. If the latch plate will not go fully into the buckle, check if the correct buckle is being used. Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary. 5. To make the lap part tight, pull up on the shoulder belt.
Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and right front passenger. Adjust the height so that the shoulder portion of the belt is centered on the shoulder. The belt should be away from the face and neck, but not falling off the shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash.
On the extended cab, push down on the release button (A) and move the height adjuster to the desired position. Extended Cab You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down, without squeezing the buttons for the regular and crew cabs, or without pushing the release button for extended cabs, to make sure it has locked into position.
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. 3.
{ 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 previously in this section. Make sure that the shoulder belt crosses the shoulder.
Safety Belt Use During Pregnancy Lap Belt (Crew and Extended Cab) 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. This section is only for the lap belt. To learn how to wear a lap-shoulder belt, see Lap-Shoulder Belt on page 1-30. Your vehicle may have a center seating position. When you sit in the center front seating position, you have a lap safety belt, which has no retractor.
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt is not long enough, your dealer/ retailer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child seats.
Child Restraints Older Children The manufacturer’s instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the below fit test: • Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. • Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue.
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. This applies belt force to the child’s pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
{ CAUTION: Never do this. Never allow a child to wear the safety belt with the shoulder belt behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt. The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries.
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. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants.
{ CAUTION: Never do this. Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it is not possible to hold it during a crash. For example, in a crash at only 40 km/h (25 mph), a 5.5 kg (12 lb) infant will suddenly become a 110 kg (240 lb) force on a person’s arms. An infant should be secured in an appropriate restraint.
{ CAUTION: Never do this. Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the right front seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If you must secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go.
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: 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. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in appropriate child restraints.
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. Secure the child restraint properly in the vehicle using the vehicle’s safety belt or LATCH system, following the instructions that came with that child restraint and the instructions in this manual. A booster seat (C-D) is a child restraint designed to improve the fit of the vehicle’s safety belt system.
To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraint systems must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH) on page 1-49 for more information. A child can be endangered in a crash if the child restraint is not properly secured in the vehicle.
Where to Put the Restraint According to accident statistics, children and infants are safer when properly restrained in a child restraint system or infant restraint system secured in a rear seating position. We recommend that children and child restraints 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.
{ CAUTION: A child in a child restraint in the center front seat can be badly injured or killed by the frontal airbags if they inflate. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in a rear seat. Do not use child restraints in the center front seat position. When securing a child restraint in a rear seating position, study the instructions that came with your child restraint to make sure it is compatible with this vehicle.
Lower Anchors Top Tether Anchor Lower anchors (A) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (B). A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle.
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. Be sure to read and follow the instructions for your child restraint. i (Top Tether Anchor): 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 For crew and extended cab models, the rear outboard seating positions have exposed metal lower anchors located in the crease between the seatback and the seat cushion. Regular Cab For regular cab models, there is an anchor symbol on the covers to assist you in locating the top tether anchors.
will be used to route the top tether through, as well as, to secure the top tether in the vehicle. Be sure to use an anchor (loop) located on the same side of the vehicle as the seating position where the child restraint will be placed. Be sure to read the instructions following to properly install a child restraint using these loops.
Securing a Child Restraint Designed for the LATCH System { CAUTION: If a LATCH-type child restraint is not attached to anchors, the child restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Install a LATCH-type child restraint properly using the anchors, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with the child restraint and the instructions in this manual.
Notice: Do not let the LATCH attachments rub against the vehicle’s safety belts. This may damage these parts. If necessary, move buckled safety belts to avoid rubbing the LATCH attachments. Do not fold the empty rear seat with a safety belt buckled. This could damage the safety belt or the seat. Unbuckle and return the safety belt to its stowed position, before folding the seat. Regular Cab Models 1.
2. See Securing a Child Restraint in the Right Front Seat Position (With Airbag Off Switch) on page 1-62 or Securing a Child Restraint in the Right Front Seat Position (With Passenger Sensing System) on page 1-66 or Securing a Child Restraint in the Right Front Seat Position (Heavy Duty Crew Cab Only) on page 1-70 for instructions on installing the child restraint using the safety belts. 2.
Example — Rear Driver’s Side Position 2.1. When using a child restraint with a top tether in the rear driver side position: A. Raise the headrest or head restraint. B. Route the top tether (B) between the headrest or head restraint posts, through the loop (A), behind the inboard headrest or head restraint post, and under the center shoulder belt (C). C. Attach the top tether (B) to the top tether anchor (loop) (D) at the center rear seating position. 2.2.
Securing a Child Restraint in a Rear Seat Position In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. When securing a child restraint in a rear seating position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle. If the child restraint does not have the LATCH system, you will be using the safety belt to secure the child restraint in this position.
For crew cab second row seatings positions, tilt the latch plate to adjust the belt if needed. 3. Push the latch plate into the buckle until it clicks. Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary.
4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 1-60 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. When installing a forward-facing child restraint, it may be helpful to use your knee to push down on the child restraint as you tighten the belt.
6. If the child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-49 for more information. 7. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it.
Securing a Child Restraint in the Right Front Seat Position (With Airbag Off Switch) This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 1-48. There may be a switch in the glove box that you can use to turn off the right front passenger frontal airbag. See Airbag Off Switch on page 1-81 for more information, including important safety information.
{ CAUTION: If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. For example, the right front passenger airbag could inflate even though the airbag on-off switch is turned off. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 3-37 for more information, including important safety information.
4. Push the latch plate into the buckle until it clicks. Position the release button so that the safety belt could be quickly unbuckled if necessary. 1-64 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
7. If your vehicle does not have a rear seat and your child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-49. 8. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. 6.
Securing a Child Restraint in the Right Front Seat Position (With Passenger Sensing System) This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 1-48. In addition, the vehicle may have a passenger sensing system which is designed to turn off the right front passenger frontal airbag under certain conditions.
If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the 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 1-49 for how and where to install your child restraint using LATCH.
4. Push the latch plate into the buckle until it clicks. Position the release button so that the safety belt could be quickly unbuckled if necessary. 1-68 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
7. If the vehicle does not have a rear seat and the child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-49 for more information. 8. Push and pull the child restraint in different directions to be sure it is secure. If the airbag is off, the off indicator in the passenger airbag status indicator will come on and stay on when the vehicle is started. 6.
Securing a Child Restraint in the Right Front Seat Position (Heavy Duty Crew Cab Only) Your vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 1-48. A label on the 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. Never put a rear-facing child restraint in the right front passenger seat.
In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. You will be using the lap-shoulder belt to secure the child restraint in this position. Follow the instructions that came with the child restraint. 1. Move the seat as far back as it will go before securing the forward-facing child restraint. 2. Put the child restraint on the seat. 3.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 1-72 6. 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.
7. If your child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-49 for more information. 8. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it.
Here are the most important things to know about the airbag system: { CAUTION: You can be severely injured or killed in a crash if you are not wearing your safety belt — even if you have airbags. Airbags are designed to work with safety belts, but do not replace them. Also, airbags are not designed to deploy in every crash. In some crashes safety belts are your only restraint. See When Should an Airbag Inflate? on page 1-77.
Where Are the Airbags? { 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. Always secure children properly in your vehicle.
Driver Side shown, Passenger Side similar The right front passenger’s airbag is in the instrument panel on the passenger’s side. 1-76 If your vehicle has roof-rail airbags for the driver, right front passenger, and second row outboard passengers, they are in the ceiling above the side windows.
When Should an Airbag Inflate? { CAUTION: If something is between an occupant and an airbag, the airbag 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. Do not put anything between an occupant and an airbag, and do not attach or put anything on the steering wheel hub or on or near any other airbag covering.
Frontal airbags may inflate at different crash speeds. For example: • If the vehicle hits a stationary object, the airbags could inflate at a different crash speed than if the vehicle hits a moving object. • If the vehicle hits an object that deforms, the airbags could inflate at a different crash speed than if the vehicle hits an object that does not deform.
Roof-rail airbags are not intended to inflate in rear impacts. Both roof-rail airbags will deploy when either side of the vehicle is struck, or if the sensing system predicts that the vehicle is about to roll over, or in a severe frontal impact. In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were.
What Will You See After an Airbag Inflates? After the frontal airbags inflate, they quickly deflate, so quickly that some people may not even realize an airbag inflated. Roof-rail airbags may still be at least partially inflated for some time after they deploy. Some components of the airbag module may be hot for several minutes. For location of the airbag modules, see What Makes an Airbag Inflate? on page 1-79. The parts of the airbag that come into contact with you may be warm, but not too hot to touch.
In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger airbag. • Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts.
This switch should only be turned to the off position if the person in the right front passenger position is a member of a passenger risk group identified by the national government as follows: Infant.
{ CAUTION: If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. For example, the right front passenger airbag could inflate even though the airbag on-off switch is turned off. United States Canada To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 3-37 for more information, including important safety information.
Passenger Sensing System If the vehicle has one of the indicators pictured in the following illustrations, then the vehicle has a passenger sensing system for the right front passenger position, unless there is an airbag off switch located in the glove box. If there is an airbag off switch, the vehicle does not have a passenger sensing system. See Airbag Off Switch on page 1-81 for more information. The passenger airbag status indicator will be visible on the overhead console when the vehicle is started.
The passenger sensing system will turn off the right front passenger frontal airbag under certain conditions. The driver airbag and the roof-rail airbags (if equipped) are not affected by the passenger sensing system. The passenger sensing system works with sensors that are part of the right front passenger seat and safety belt. The sensors are designed to detect the presence of a properly-seated occupant and determine if the right front passenger frontal airbag should be enabled (may inflate) or not.
The passenger sensing system is designed to turn off the right front passenger frontal airbag if: • The right front passenger seat is unoccupied. • The system determines an infant is present in a child restraint. • A right front passenger takes his/her weight off of the seat for a period of time.
If the On Indicator is Lit for a Child Restraint If a child restraint has been installed and the on indicator is lit: 1. Turn the vehicle off. 2. Remove the child restraint from the vehicle. 3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers. 4.
If the Off Indicator is Lit for an Adult-Size Occupant If this happens, use the following steps to allow the system to detect that person and enable the right front passenger frontal airbag: 1. Turn the vehicle off. 2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers. 3. Place the seatback in the fully upright position. 4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended. 5.
Additional Factors Affecting System Operation Safety belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See “Safety Belts” and “Child Restraints” in the Index for additional information about the importance of proper restraint use. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged.
Servicing Your Airbag-Equipped Vehicle Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer/retailer and the service manual have information about servicing the vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 7-15.
Any object, such as an aftermarket seat heater or a comfort enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing system from properly turning off the passenger airbag(s). See Passenger Sensing System on page 1-84.
Restraint System Check Airbags Checking the Restraint Systems The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light on page 3-37 for more information. Safety Belts Now and then, check that the safety belt reminder light, safety belts, buckles, latch plates, retractors, and anchorages are all working properly.
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. If the vehicle has the LATCH system and it was being used during a crash, you may need new LATCH system parts.

Plug the cord into a normal, grounded 110-volt AC outlet. { CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured.
Automatic Transmission Operation If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. Vehicles with an automatic transmission have an electronic shift position indicator within the instrument panel cluster. This display comes on when the ignition key is turned to the ON/RUN position. There are several different positions for the shift lever. Heavy Duty 6-Speed Automatic Transmission Shown (Light Duty 6 Speed Similar) See “Range Selection Mode” later in this section.
{ CAUTION: { CAUTION: It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have Four-Wheel Drive, the vehicle will be free to roll — even if the shift lever is in P (Park) — if the 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 on page 2-52.
N (Neutral): In this position, the engine does not connect with the wheels. To restart when you are already moving, use N (Neutral) only. Also, use N (Neutral) when the vehicle is being towed. D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, and you are: • Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. { CAUTION: Shifting into a drive gear while the engine is running at high speed is dangerous.
The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position, and vehicle load.
1 (First): For the Hydra-Matic® 4-Speed transmission this position reduces vehicle speed even more than 2 (Second) 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 1 (First) while the vehicle is moving forward, the transmission does not shift into first gear until the vehicle is going slowly enough.
To use this feature, do the following: 1. Move the shift lever to M (Manual Mode). 2. Press the plus/minus buttons, located on the steering column shift lever, to select the desired range of gears for current driving conditions. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires.
Tow/Haul Mode Also see Tow Haul Mode under Towing a Trailer on page 4-50 for more information. Tow/Haul Mode (Allison Transmission® or Hydra-Matic® 6-Speed Automatic Transmission) Vehicles with an automatic transmission have a 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 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 3-51 for more information. Also see “Tow Haul Mode” under Towing a Trailer on page 4-50 for more information.
Four-Wheel Drive Manual Transfer Case If the vehicle has Four-Wheel Drive, you can send the engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of Four-Wheel Drive, you must be familiar with its operation. Read the following before using Four-Wheel Drive. See the appropriate text for the transfer case in the vehicle.
A Four-Wheel Drive indicator light comes on when you shift into four-wheel drive and the front axle engages. See Four-Wheel-Drive Light on page 3-51. 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 2 m 4 m 4 n N YES Notice: Driving on clean, dry pavement in four-wheel drive for an extended period of time can cause premature wear on the vehicle’s powertrain.
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 into N (Neutral). N (Neutral): Shift to this setting only when the vehicle needs to be towed. See Recreational Vehicle Towing on page 4-45 or Towing Your Vehicle on page 4-45. 2 m (Two-Wheel-Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive.
When Using the Manual Transfer Case • Shifting should be made using quick motions. Shifting slowly may make it more difficult to shift. • You may notice that it is harder to shift when the vehicle is cold. After the vehicle warms up the shifting will return to normal. Shifting from Two-Wheel-Drive High to Four-Wheel-Drive High • Shifts between Two-Wheel-Drive High and Four-Wheel-Drive High can be made at any vehicle speed.
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).
Electronic Transfer Case You can choose among four driving settings: The transfer case knob is located next to the steering column. Use the dial to shift into and out of four-wheel drive. Indicator lights in the dial show which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take the vehicle to your dealer/retailer for service.
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 the 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, the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in N (Neutral) and the ignition in ON/RUN. The preferred method for shifting out of Four-Wheel-Drive Low is to have the 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.
7. If the engine is running, verify that the transfer case is in N (Neutral) by shifting the transmission to R (Reverse) for one second, then shift the transmission to D (Drive) for one second. 8. Turn the ignition to ACC/ACCESSORY, which will turn the engine off. 9. Place the transmission shift lever in P (Park). 10. Release the parking brake prior to moving the vehicle. 11. Turn the ignition to LOCK/OFF. Shifting Out of Neutral To shift the transfer case out of N (Neutral) do the following: 1.
Use the dial to shift into and out of Four-Wheel Drive. You can choose among five driving settings: Indicator lights in the dial show which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take the vehicle to your dealer/retailer for service. An indicator light will flash while shifting the transfer case. It will remain illuminated when the shift is complete.
{ CAUTION: Shifting the transfer case to N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in N (Neutral). See Parking Brake on page 2-50. N (Neutral): Shift the vehicle’s transfer case to N (Neutral) only when towing the vehicle. See Recreational Vehicle Towing on page 4-45 or Towing Your Vehicle on page 4-45 for more information.
You must wait for the Four-Wheel-Drive Low indicator light to stop flashing and remain on before shifting the transmission into gear. Notice: Shifting the transmission into gear before the requested mode indicator light has stopped flashing could damage the transfer case. To help avoid damaging the vehicle, always wait for the mode indicator lights to stop flashing before shifting the transmission into gear.
Shifting into Neutral To shift the transfer case to N (Neutral) do the following: 1. Make sure the vehicle is parked so that it will not roll. 2. Set the parking brake and apply the regular brake pedal. See Parking Brake on page 2-50 for more information. 3. Start the vehicle or turn the ignition to ON/RUN. 4. Put the transmission in N (Neutral). 5. Shift the transfer case to Two-Wheel Drive High. 6.
Parking Brake 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). To release the parking brake, hold the regular brake pedal down. Then pull the bottom edge of the lever with the parking brake symbol, located above the parking brake pedal. If the ignition is on when the parking brake is released, the brake system warning light goes off.

Make sure that the parking brake is fully released and the brake warning light is off before driving. To release the parking brake, hold the regular brake pedal down, then push down momentarily on the parking brake pedal until you feel the pedal release. Slowly pull your foot up off the park brake pedal.
Shifting Into Park 2. Move the shift lever into the P (Park) position by pulling the shift lever toward you and moving it up as far as it will go. { CAUTION: 3. Be sure the transfer case is in a drive gear — not in N (Neutral). It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.
Leaving the Vehicle With the Engine Running { CAUTION: It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set. If you have four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So be sure the transfer case is in a drive gear — not in N (Neutral).
Shifting Out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: • Prevent ignition key removal unless the shift lever is in P (Park) with the shift lever button fully released, and • Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN or ACC/ACCESSORY and the regular brake pedal is applied.
Engine Exhaust CAUTION: (Continued) • The vehicle’s exhaust system has been { CAUTION: modified, damaged or improperly repaired. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if: • The vehicle idles in areas with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes). • The exhaust smells or sounds strange or different.
Running the Vehicle 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 a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation.
Automatic Dimming Rearview Mirror { CAUTION: Four-wheel drive vehicles with the transfer case in N (Neutral) will allow the vehicle to roll, even if the automatic transmission shift lever is in P (Park).

If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system.
Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power.
This light comes on briefly when the ignition key is turned to ON/RUN. If it does not come on then, have it fixed so it is ready to warn if there is a problem. { CAUTION: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.
StabiliTrak® Indicator Light For vehicles with the StabiliTrak® system, this light comes on briefly while starting the engine. Engine Coolant Temperature Gage (US-Canada) If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on and stays on while driving, there could be a problem with the StabiliTrak® system and the vehicle might need service.
Tire Pressure Light For vehicles with a tire pressure monitoring system, this light comes on briefly when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is On Steady This indicates that one or more of the tires is significantly underinflated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See DIC Warnings and Messages on page 3-66 for more information.
If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction.
Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. An emission system malfunction might be corrected by doing the following: • Make sure the fuel cap is fully installed. See Filling the Tank on page 5-10. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere.
Emissions Inspection and Maintenance Programs Oil Pressure Gage (US-Canada) Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection: • The vehicle will not pass this inspection if the check engine light is on with the engine running, or if the key is in ON/RUN and the light is not on.
A reading outside the normal operating range can be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the vehicle’s oil as soon as possible. See “OIL PRESSURE LOW” under DIC Warnings and Messages on page 3-66 and Engine Oil on page 5-15. Oil Pressure Light { CAUTION: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches fire. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.

Your Driving, the Road, and the Vehicle Driving for Better Fuel Economy Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible. • • • • Avoid fast starts and accelerate smoothly. Brake gradually and avoid abrupt stops. Avoid idling the engine for long periods of time. When road and weather conditions are appropriate, use cruise control, if equipped. • Always follow posted speed limits or drive more slowly when conditions require.
Drunk Driving { CAUTION: Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink. Death and injury associated with drinking and driving is a global tragedy.
Control of a Vehicle The following three systems help to control the vehicle while driving — brakes, steering, and accelerator. At times, as when driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. Meaning, you can lose control of the vehicle. See StabiliTrak® System on page 4-6. Adding non-dealer/non-retailer accessories can affect vehicle performance. See Accessories and Modifications on page 5-4.
Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on. This is normal. If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 3-43.
Braking in Emergencies StabiliTrak® System ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking. The vehicle may have a vehicle stability enhancement system called StabiliTrak. It is an advanced computer controlled system that assists the driver with directional control of the vehicle in difficult driving conditions. Brake Assist (Except With 4.
If cruise control is being used when StabiliTrak activates, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 3-13 for more information. 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.
TCS and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason. When TCS or StabiliTrak is turned off, the StabiliTrak light and the appropriate message will be displayed on the DIC to warn the driver. The vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system. See “Traction Control Operation” next for more information.
The traction control system may activate on dry or rough roads or under conditions such as heavy acceleration while turning or abrupt upshifts/downshifts of the transmission. When this happens, a reduction in acceleration may be noticed, or a noise or vibration may be heard. This is normal. Steering If cruise control is being used when the system activates, the StabiliTrak light will flash and cruise control will automatically disengage. Cruise control may be reengaged when road conditions allow.
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. These problems can be avoided by braking — if you can stop in time. But sometimes you cannot stop in time because there is no room. That is the time for evasive action — steering around the problem.
Off-Road Recovery Passing The vehicle’s right wheels can drop off the edge of a road onto the shoulder while driving. Passing another vehicle on a two-lane road can be dangerous. To reduce the risk of danger while passing: • Look down the road, to the sides, and to crossroads for situations that might affect a successful pass. If in doubt, wait. • Watch for traffic signs, pavement markings, and lines that could indicate a turn or an intersection.
Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to the vehicle’s three control systems. In the braking skid, the wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force.
Drinking and driving can be very dangerous on any road and this is certainly true for off-road driving. At the very time you need special alertness and driving skills, your reflexes, perceptions, and judgment can be affected by even a small amount of alcohol. You could have a serious — or even fatal — accident if you drink and drive or ride with a driver who has been drinking. Before You Go Off-Roading • Have all necessary maintenance and service work done.
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 air dam is held in place by two bolts and 10 snaps accessible from underneath the front fascia. To remove the air dam: 1. Remove the two outboard air dam bolts. 2. With a flat-blade tool, disengage the snaps. Loading Your Vehicle for Off-Road Driving { CAUTION: • Cargo on the load floor piled higher than the 3.
There are some important things to remember about how to load your vehicle. • Always carry a litter bag and make sure all refuse is removed from any campsite before leaving. • The heaviest things should be on the floor, forward • Take extreme care with open fires (where of the rear axle. Put heavier items as far forward as you can. permitted), camp stoves, and lanterns. • Be sure the load is properly secured, so things are not tossed around.
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-roading requires some new and different skills. Tune your senses to different kinds of signals. Your eyes need to constantly sweep the terrain for unexpected obstacles. Your ears need to listen for unusual tire or engine sounds. Use your arms, hands, feet, and body to respond to vibrations and vehicle bounce.
Surface Obstacles: Unseen or hidden obstacles can be hazardous. A rock, log, hole, rut, or bump can startle you if you are not prepared for them. Often these obstacles are hidden by grass, bushes, snow, or even the rise and fall of the terrain itself.
Approaching a Hill Driving Uphill When you approach a hill, decide if it is 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 might not see this because the crest of the hill is hidden by bushes, grass, or shrubs.
• Attach a flag to the vehicle to be more visible to approaching traffic on trails or hills. • Sound the horn as you approach the top of the hill to let opposing traffic know you are there. • Use headlamps even during the day to make the vehicle more visible to oncoming traffic. { CAUTION: Driving to the top (crest) of a hill at full speed can cause an accident. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed.
Things not to do if the vehicle stalls, or is about to stall, when going up a hill: • Never attempt to prevent a stall by shifting into N (Neutral) to rev-up the engine and regain forward momentum. This will not work. The vehicle can roll backward very quickly and could go out of control. • Never try to turn around if about to stall when going up a hill. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over.
• 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, try to keep the vehicle headed straight down. Use a low gear so engine drag can help the brakes so they do not have to do all the work. Descend slowly, keeping the vehicle under control at all times. { CAUTION: Heavy braking when going down a hill can cause your brakes to overheat and fade.
Driving Across an Incline An off-road trail will probably go across the incline of a hill. To decide whether to try to drive across the incline, consider the following: • Surface conditions can be a problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it — a rock, a rut, etc. — and roll over.
Stalling on an Incline { CAUTION: Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path. If the vehicle stalls when crossing an incline, be sure you, and any passengers, get out on the uphill side, even if the door there is harder to open.
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 driving through it.
Driving at Night Driving in Rain and on Wet Roads Night driving is more dangerous than day driving because some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue. Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water. Night driving tips include: • Drive defensively.
Hydroplaning Before Leaving on a Long Trip Hydroplaning is dangerous. Water can build up under your vehicle’s tires so they 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. To prepare your vehicle for a long trip, consider having it serviced by your dealer/retailer before departing.
Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: • Keep the vehicle serviced and in good shape. • Check all fluid levels and brakes, tires, cooling system, and transmission. • Going down steep or long hills, shift to a lower gear. { CAUTION: If you do not shift down, the brakes could get so hot that they would not work well.
Winter Driving Driving on Snow or Ice Drive carefully when there is snow or ice between the tires and the road, creating less traction or grip. Wet ice can occur at about 32°F (0°C) when freezing rain begins to fall, resulting in even less traction. Avoid driving on wet ice or in freezing rain until roads can be treated with salt or sand. Drive with caution, whatever the condition. Accelerate gently so traction is not lost.
CAUTION: { CAUTION: Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. If the vehicle is stuck in the snow: • Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust pipe. • Check again from time to time to be sure snow does not collect there.
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. See Rocking Your Vehicle to Get It Out on page 4-30. If the vehicle has a traction system, it can often help to free a stuck vehicle. Refer to the vehicle’s traction system in the Index. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method.
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. Notice: Never use recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.
Loading the 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 5-64 and Inflation - Tire Pressure on page 5-73. 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 4-34 Description Vehicle Capacity Weight for Example 1 = Subtract Occupant Weight 150 lbs (68 kg) × 2 = Available Occupant and Cargo Weight = Example 2 Total 1,000 lbs (453 kg) Item 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 (340 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) 1,000 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.
The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). 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.
{ CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. • Put things in the cargo area of your vehicle. Try to spread the weight evenly. • Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. • Do not leave an unsecured child restraint in your vehicle. • When you carry something inside the vehicle, secure it whenever you can. • Do not leave a seat folded down unless you need to.
Add-On Equipment When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment. Adding a Snow Plow or Similar Equipment Notice: Overloading your vehicle may cause damage. Repairs would not be covered by your warranty. Do not overload your vehicle. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle.
The plow your vehicle can carry depends on many things, such as: • The options your vehicle came with, and the weight of those options. • The weight and number of passengers you intend to carry. • The weight of items you have added to your vehicle, like a tool box or truck cap. • The total weight of any additional cargo you intend to carry. 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).
Front axle reserve capacity is the difference between your front Gross Axle Weight Rating (GAWR) and the front axle weight of your vehicle with full fuel and passengers. Basically, it is the amount of weight you can add to your front axle before reaching your front GAWR.
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.
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. Your dealer/retailer can also help you with this. The total vehicle reserve capacity for your vehicle can be found in the lower right corner of the Certification/Tire label as shown previously.
Refer to the Truck-Camper Loading Information label in the glove box for dimensions A and B as shown in the following illustration. Use the rear edge of the load floor for measurement purposes. The recommended location for the cargo center of gravity is at point C for the CWR. It is the point where the mass of a body is concentrated and, if suspended at that point, would balance the front and rear. Here is an example of proper truck and camper match: A. Camper Center of Gravity B.
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. If your slide-in camper and its load weighs less than the CWR, the center of gravity zone for your vehicle may be larger. Your dealer can help you make a good vehicle-camper match and help you determine the CWR.
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.
Dinghy Towing Four-Wheel-Drive Vehicles Two-Wheel-Drive Vehicles Use the following procedure to dinghy tow a four-wheel-drive vehicle: Notice: If the vehicle is towed with all four wheels on the ground, the drivetrain components could be damaged. The repairs would not be covered by the vehicle warranty. Do not tow the vehicle with all four wheels on the ground. Two-wheel-drive vehicles should not be towed with all four wheels on the ground.
Dolly Towing { CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). The driver or others could be injured. Make sure the parking brake is firmly set before the transfer case is shifted to N (Neutral). Front Towing (Front Wheels Off the Ground) Two-Wheel-Drive Vehicles 4. Shift the transfer case to N (Neutral).
To dolly tow a two-wheel-drive vehicle, the vehicle must be towed with the rear wheels on the dolly. See “Rear Towing (Rear Wheels Off the Ground)” later in this section for more information. Four-Wheel-Drive Vehicles { CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). The driver or others could be injured. Make sure the parking brake is firmly set before the transfer case is shifted to N (Neutral). 5.
Rear Towing (Rear Wheels Off the Ground) 3. Firmly set the parking brake. See Parking Brake on page 2-50. 4. Put the transmission in P (Park). 5. Secure the vehicle to the dolly following the manufacturer’s instructions. 6. Use an adequate clamping device designed for towing to ensure that the front wheels are locked into the straight position. 7. Turn the ignition to LOCK/OFF. Four-Wheel-Drive Vehicles Use the following procedure to dolly tow a four-wheel-drive vehicle from the rear: 1.
6. Use an adequate clamping device designed for towing to ensure that the front wheels are locked into the straight position. { CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). The driver or others could be injured. Make sure the parking brake is firmly set before the transfer case is shifted to N (Neutral). 7. Shift the transfer case to N (Neutral).
Notice: Pulling a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To pull a trailer correctly, follow the advice in this section and see your dealer/retailer for important information about towing a trailer with the vehicle. To identify the trailering capacity of the vehicle, read the information in “Weight of the Trailer” that appears later in this section. Trailering is different than just driving the vehicle by itself.
Weight of the Trailer How heavy can a trailer safely be? It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature and how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” later in this section for more information.

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total gross weight of the vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle. If there are a lot of options, equipment, passengers or cargo in the vehicle, it will reduce the tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow.
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).
Since tongue weight is usually at least 10 percent of total loaded trailer weight, expect that the largest trailer the vehicle can properly handle is 6,000 lbs (2 721 kg). Weight-Distributing Hitches and Weight Carrying Hitches It is important that the vehicle does not exceed any of its ratings — GCWR, GVWR, RGAWR, Maximum Trailer Rating or Tongue Weight. The only way to be sure it is not exceeding any of these ratings is to weigh the vehicle and trailer.
If a step-bumper hitch will be used, 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 the loaded trailer being pulled 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.
Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. If the trailer being towed weighs up to 5,000 lbs (2 271 kg) with a factory-installed step bumper, safety chains may be attached to the attaching points on the bumper.
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.
Integrated Trailer Brake Control System The vehicle may have an Integrated Trailer Brake Control (ITBC) system for electric trailer brakes. This symbol is located on the Trailer Brake Control Panel on vehicles with an Integrated Trailer Brake Control System. The power output to the trailer brakes is based on the amount of brake pressure being applied by the vehicle’s brake system. This available power output to the trailer brakes can be adjusted to a wide range of trailering situations.
Trailer Brake Control Panel CAUTION: (Continued) with surge, air or electric-over-hydraulic trailer brake systems. To determine the type of brakes on the trailer and the availability of controllers, check with your trailer manufacturer or dealer/retailer. When trailering, make sure of the following: • The ITBC system is used only with trailers that are equipped with electric brakes. • All applicable local and federal laws and regulations are followed.
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 3-66 for more information. The display page indicates Trailer Gain setting, power output to the electric trailer brakes, trailer connection and system operational status.
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). 0.0 (zero) gain is the factory default setting. To properly adjust trailer gain, see the Trailer Gain Adjustment Procedure later in this section. TRAILER OUTPUT – This is displayed any time a trailer with electric brakes is connected. Output to the electric brakes is based on the amount of vehicle braking present and relative to the Trailer Gain setting.
A trailer that is under-gained may result in not enough trailer braking. Both of these conditions may result in poorer stopping and stability of the vehicle and trailer. Use the following procedure to correctly adjust Trailer Gain for each towing condition: 1. Make sure the trailer brakes are in proper working condition. 2. Connect a properly loaded trailer to the vehicle and make all necessary mechanical and electrical connections. See Loading the Vehicle on page 4-32 for more information. 3.
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.
SERVICE TRAILER BRAKE SYSTEM – This message will be displayed when there is a problem with the ITBC system. If this message persists over multiple ignition cycles there is a problem with the ITBC system. Take the vehicle to an authorized GM dealer to have the ITBC system diagnosed and repaired. If either the CHECK TRAILER WIRING or SERVICE TRAILER BRAKE SYSTEM message is displayed while driving the vehicle, power is no longer available to the trailer brakes.
Towing a trailer requires a certain amount of experience. Get to know the rig before setting out for the open road. Get acquainted with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now longer and not as responsive as the vehicle is by itself. Following Distance Before starting, check all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires and mirror adjustments.
Making Turns Driving On Grades Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. The vehicle could be damaged. Avoid making very sharp turns while trailering. Reduce speed and shift to a lower gear before starting down a long or steep downgrade. If the transmission is not shifted down, the brakes might have to be used so much that they would get hot and no longer work well. When turning with a trailer, make wider turns than normal.
Parking on Hills { CAUTION: Parking the vehicle on a hill with the trailer attached can be dangerous. If something goes wrong, the rig could start to move. People can be injured, and both the vehicle and the trailer can be damaged. When possible, always park the rig on a flat surface. If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill. 2.
Leaving After Parking on a Hill 1. Apply and hold the brake pedal while you: • Start the engine • Shift into a gear • Release the parking brake 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing The vehicle needs service more often when pulling a trailer. See this manual’s Maintenance Schedule or Index for more information.
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/retailer 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 drivers side of the vehicle, attached to the frame bracket. A connector must be added to the wiring harness which connects to the camper.
Electric Brake Control Wiring Provisions These wiring provisions are included with the vehicle as part of the trailer wiring package. These provisions are for an electric brake controller. The instrument panel contains blunt cut wires behind the steering column for the trailer brake controller.

Service Accessories and Modifications For service and parts needs, visit your dealer/retailer. You will receive genuine GM parts and GM-trained and supported service people. When non-dealer/non-retailer accessories are added to the vehicle, they can affect vehicle performance and safety, including such things as airbags, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control, and stability control.
California Proposition 65 Warning Doing Your Own Service Work 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. If this vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information.
This vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-90. Keep a record with all parts receipts and list the mileage and the date of any service work performed. See Maintenance Record on page 6-19. Adding Equipment to the Outside of the Vehicle Things added to the outside of the vehicle can affect the airflow around it. This can cause wind noise and can affect fuel economy and windshield washer performance.
notice a slight audible knocking noise, commonly referred to as spark knock. If the octane is less than 87, you might notice a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service.
Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels. Fuel E85 (85% Ethanol) Notice: This vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol.
At a minimum, E85 should meet ASTM Specification D 5798. By definition, this means that fuel labeled E85 will have an ethanol content between 70% and 85%. Filling the fuel tank with fuel mixtures that do not meet ASTM specifications can affect driveability and could cause the malfunction indicator lamp to come on. To ensure quick starts in the wintertime, the E85 fuel must be formulated properly for your climate according to ASTM specification D 5798.
Filling the Tank If the vehicle has the DURAMAX Diesel engine, see the DURAMAX Diesel manual for more information. { CAUTION: Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off the engine when you are refueling. Do not smoke if you are near fuel or refueling the vehicle. Do not use cellular phones. Keep sparks, flames, and smoking materials away from fuel.
{ 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 the 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. If the vehicle is a dual fuel tank chassis cab model, and it runs out of fuel, refuel the front fuel tank first to ensure a quick restart. Be careful not to spill fuel.
Filling a Portable Fuel Container Checking Things Under the Hood { CAUTION: Never fill a portable fuel container while it is in the vehicle. Static electricity discharge from the container can ignite the fuel vapor. You can be badly burned and the vehicle damaged if this occurs. To help avoid injury to you and others: • Dispense fuel only into approved containers. • Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed, or on any surface other than the ground.
Hood Release To open the hood: 1. Pull the handle with this symbol on it. It is located inside the vehicle to the left of the brake pedal. 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.

E. Engine Oil Fill Cap. See “When to Add Engine Oil” under Engine Oil on page 5-15. F. Automatic Transmission Dipstick. See “Checking the Fluid Level” under Automatic Transmission Fluid (4-Speed Transmission) on page 5-21 or Automatic Transmission Fluid (6-Speed Transmission) on page 5-24. G.
When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-129. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged.
What Kind of Engine Oil to Use Look for three things: • American Petroleum Institute (API) starburst symbol Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Notice: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol.
Engine Oil Additives / Engine Oil Flushes Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all that is needed for good performance and engine protection. Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty. Engine Oil Life System When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil and filter.
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 the oil is changed 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.
When to Inspect the Engine Air Cleaner/Filter Replacing the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance (Gasoline Engine) on page 6-4 for more information. If driving on dusty/dirty conditions, inspect the filter at each engine oil change.
{ 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.
How to Check Automatic Transmission Fluid Because this operation can be a little difficult, you may choose to have this done at the dealer/retailer service department. If you do it yourself, be sure to follow all the instructions here or you could get a false reading on the dipstick. Notice: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire.
Then, without shutting off the engine, follow these steps: 1. Locate the transmission dipstick handle with this graphic which is located at the rear of the engine compartment, on the passenger side of the vehicle. See Engine Compartment Overview on page 5-14 for more information on location. 2. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. 3. Push it back in all the way, wait three seconds and then pull it back out again. 4.
How to Add Automatic Transmission Fluid Automatic Transmission Fluid (6-Speed Transmission) Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Recommended Fluids and Lubricants on page 6-15. When to Check and Change Automatic Transmission Fluid Using a funnel, add fluid down the transmission dipstick tube only after checking the transmission fluid while it is hot. A cold check is used only as a reference.
How to Check Automatic Transmission Fluid Notice: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid. Before checking the fluid level, prepare the vehicle as follows: 1. Start the engine and park the vehicle on a level surface.
Cold Check Procedure Use this procedure only as a reference to determine if the transmission has enough fluid to be operated safely until a hot check procedure can be made. The hot check procedure is the most accurate method to check the fluid level. Perform the hot check procedure at the first opportunity. Use this cold check procedure to check fluid level when the transmission temperature is between 80°F and 90°F (27°C and 32°C). 1.
Hot Check Procedure Use this procedure to check the transmission fluid level when the transmission fluid temperature is between 160°F and 200°F (71°C and 93°C). 4. Check both sides of the dipstick and read the lower level. Repeat the check procedure to verify the reading. The hot check is the most accurate method to check the fluid level. The hot check should be performed at the first opportunity in order to verify the cold check.
Consistency of Readings Always check the fluid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If readings are still inconsistent, contact your dealer/retailer. Cooling System If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. The Cooling System allows the engine to maintain the correct working temperature. 5.3L Engine (4.3L, 4.8L, 6.0L and 6.2L Similar) A.
{ 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. Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 miles) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty.
What to Use Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant. If using this mixture, nothing else needs to be added. This mixture: { CAUTION: • Gives freezing protection down to −34°F (−37°C), Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant The coolant surge tank is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 5-14 for more information on location. The vehicle must be on a level surface when checking the coolant level. Check to see if coolant is visible in the coolant surge tank. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down.
How to Add Coolant to the Coolant Surge Tank for Gasoline Engines If the vehicle has a diesel engine, see “Cooling System” in the DURAMAX® Diesel Supplement for the proper coolant fill procedure. { CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. 5-32 Notice: This vehicle has a specific coolant fill procedure.
{ CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap. If no coolant is visible in the surge tank, add coolant as follows: 1.
5. Replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 6. Verify coolant level after engine is shut off and the coolant is cold. If necessary, repeat coolant fill procedure Steps 1 through 6. 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. Engine Overheating If the vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. 3.
You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 7-7. If you do decide to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced.
If No Steam Is Coming From The Engine Compartment 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 4-50.
Overheated Engine Protection Operating Mode If an overheated engine condition exists and the REDUCED ENGINE POWER message is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows the vehicle to be driven to a safe place in an emergency. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided.
Power Steering Fluid See Engine Compartment Overview on page 5-14 for reservoir location. How to Check Power Steering Fluid To check the power steering fluid: 1. Turn the key off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look at the fluid level on the dipstick.
Windshield Washer Fluid Notice: • When using concentrated washer fluid, follow What to Use When windshield washer fluid needs to be added, be sure to read the manufacturer’s instructions before use. Use a fluid that has sufficient protection against freezing in an area where the temperature may fall below freezing. Adding Washer Fluid The vehicle has a low washer fluid message in the DIC that comes on when the washer fluid is low.
Brakes Brake Fluid The brake master cylinder reservoir is filled with DOT 3 brake fluid. See Engine Compartment Overview on page 5-14 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down: • The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up. • A fluid leak in the brake hydraulic system can also cause a low fluid level.
Checking Brake Fluid Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 5-14. The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak. { CAUTION: With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid. Notice: • Using the wrong fluid can badly damage brake hydraulic system parts.
Brake Wear This vehicle has front disc brakes and could have rear drum brakes or rear disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly. { CAUTION: The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident.
Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced — for example, when the brake linings wear down and new ones are installed — be sure to get new approved replacement parts. If this is not done, the brakes might not work properly.
Jump Starting If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. If the 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.
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: 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. 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. If it is low, add water to take care of that first. If you do not, explosive gas could be present.
7. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. { CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 6. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know.
10. Connect the other end of the negative (−) cable to a heavy, unpainted metal engine part or to the remote negative (−) terminal, on the vehicle with the dead battery. 11. Start the vehicle with the good battery and run the engine for a while. 12. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service. Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle.
To disconnect the jumper cables from both vehicles do the following: 1. Disconnect the black negative (−) cable from the vehicle that had the bad battery. 2. Disconnect the black negative (−) cable from the vehicle with the good battery. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle.
• For all 6.0L and 6.2L 2500HD Series applications, the proper level is from 0 to 0.5 inches (0 mm to 13 mm) below the bottom of the filler plug hole, located on the rear axle. Add only enough fluid to reach the proper level. • For all 6.6L DURAMAX DIESEL 2500HD Series applications and all 3500 Series applications, the proper level is from 0.6 inches to 0.8 inches (17 mm to 21 mm) below the bottom of the filler plug hole, located on the rear axle.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected for wear or cracking. See Scheduled Maintenance (Gasoline Engine) on page 6-4 for more information on wiper blade inspection. Replacement blades come in different types and are removed in different ways. Here is how to remove the wiper blade: 1. Pull the windshield wiper arm connector away from the windshield. 3. Install the new blade onto the arm connector and make sure the grooved areas are fully set in the locked position.
20-Inch Tires { CAUTION: Poorly maintained and improperly used tires are dangerous. • Overloading your vehicle’s tires can cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Loading the Vehicle on page 4-32. • 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.
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. (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.
(G) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. For information on recommended tire pressure see Inflation - Tire Pressure on page 5-73 and Loading the Vehicle on page 4-32. (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 Identification Number (TIN): The letters and numbers following DOT code are the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture. Tire Size The following examples show the different parts of a tire size. (F) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread.
(C) Aspect Ratio: A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 75, as shown in item C of the tire illustration, it would mean that the tire’s sidewall is 75 percent as high as it is wide. (D) Construction Code: A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction.
(D) Construction Code: A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction. Aspect Ratio: The relationship of a tire’s height to its width. Belt: A rubber coated layer of cords that is located between the plies and the tread. Cords may be made from steel or other reinforcing materials.
GVWR: Gross Vehicle Weight Rating. See Loading the Vehicle on page 4-32. GAWR FRT: Gross Axle Weight Rating for the front axle. See Loading the Vehicle on page 4-32. GAWR RR: Gross Axle Weight Rating for the rear axle. See Loading the Vehicle on page 4-32. 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.
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. Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided.
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 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). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement.
Dual Tire Operation Tire Pressure Monitor System When the vehicle is new, or whenever a wheel, wheel bolt or wheel nut is replaced, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper torque and wheel nut tightening information, see Removing the Spare Tire and Tools on page 5-93. The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. 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.
Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the vehicle’s tires and transmits the tire pressure readings to a receiver located in the vehicle.
TPMS Malfunction Light and Message The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected.
TPMS Sensor Matching Process 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 side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service.
5. 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 may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. 6. Proceed to the passenger side front tire, and repeat the procedure in Step 5. 7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5. 8.
If your vehicle has single rear wheels and the tread design for the front tires is the same as the rear tires, use the rotation pattern shown here when rotating the tires. If your vehicle has dual rear wheels and the tread design for the front tires is the same as the rear tires, always use one of the correct rotation patterns shown here when rotating the 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 the 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 Various factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions, influence when you need 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.
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 the 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 the 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 Uniform Tire Quality Grading 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.
Treadwear Temperature – A, B, C 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.
Wheel Alignment and Tire Balance The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment might need to be checked.
CAUTION: (Continued) lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis.
Tire Chains CAUTION: { CAUTION: If your vehicle has dual wheels or P265/65R18, P275/55R20 or LT265/70R17 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash.
If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is much more likely to leak out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on the hazard warning flashers. See Hazard Warning Flashers on page 3-8. CAUTION: (Continued) 5. Do not allow passengers to remain in the vehicle. 6. Put the wheel 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. { CAUTION: Changing a tire can be dangerous.

Tilt the tire toward the vehicle with some slack in the cable to access the tire/wheel retainer. Separate the retainer from the guide pin by sliding the retainer up the pin while pressing down on the latch. 7. Put the spare tire near the flat tire.
Removing the Flat Tire and Installing the Spare Tire Use the following pictures and instructions to remove the flat tire and raise the vehicle. 2. If your vehicle has wheel nut caps, loosen them by turning the wheel wrench counterclockwise. If the vehicle has a center cap with wheel nut caps, the wheel nut caps are designed to stay with the center cap after they are loosened. Remove the entire center cap.
If the wheel has a smooth center cap, place the chisel end of the wheel wrench in the slot on the wheel, and gently pry it out. 3. Use the wheel wrench and turn it counterclockwise to loosen the wheel nuts. Do not remove the wheel nuts yet.
Front Position - 1500 Models Front Position - All Other Models 4. Position the jack under the vehicle as shown. If the flat tire is on the front of the vehicle (1500 Model vehicles), position the jack under the bracket attached to the vehicle’s frame, behind the flat tire. If the flat tire is on the front of the vehicle (all other models), position the jack on the frame behind the flat tire.
{ CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. 5. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit under the wheel well. 6. Remove all the wheel nuts and take off the flat tire.
8. Install the spare tire. { CAUTION: { CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-92. 7.
CAUTION: { CAUTION: If wheel studs are damaged, they can break. If all the studs on a wheel broke, the wheel could come off and cause a crash. If any stud is damaged because of a loose-running wheel, it could be that all of the studs are damaged. To be sure, replace all studs on the wheel. If the stud holes in a wheel have become larger, the wheel could collapse in CAUTION: (Continued) (Continued) operation. Replace any wheel if its stud holes have become larger or distorted in any way.
{ CAUTION: Wheel nuts that are improperly or incorrectly tightened can cause the wheels to become loose or come off. The wheel nuts should be tightened with a torque wrench to the proper torque specification after replacing. Follow the torque specification supplied by the aftermarket manufacturer when using accessory locking wheel nuts. See Capacities and Specifications on page 5-129 for original equipment wheel nut torque specifications.
Secondary Latch System Your vehicle has an underbody-mounted tire hoist assembly equipped with a secondary latch system. It is designed to stop the spare tire from suddenly falling off your vehicle. For the secondary latch to work, the spare must be installed with the valve stem pointing down. See Storing a Flat or Spare Tire and Tools on page 5-108. To release the spare tire from the secondary latch: 1. Check under the vehicle to see if the cable end is visible.
6. Stand the wheel blocks on their shortest ends, with the backs facing each other. 7. Place the bottom edge of the jack (A) on the wheel blocks (B), separating them so that the jack is balanced securely. 8. Attach the jack handle, extension, and wheel wrench to the jack and place it (with the wheel blocks) under the vehicle toward the front of the rear bumper.
{ CAUTION: Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from under the spare. 9. Position the center lift point of the jack under the center of the spare tire. 10. Turn the wrench clockwise to raise the jack until it lifts the end fitting. 11. Continue raising the jack until the spare tire stops moving upward and is held firmly in place.
Storing a Flat or Spare Tire and Tools { CAUTION: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. Notice: Storing an aluminum wheel with a flat tire under your vehicle for an extended period of time or with the valve stem pointing up can damage the wheel.
1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down, and to the rear. 3. Attach the wheel wrench (H) and extensions (I) together, as shown. 2. Separate the tire/wheel retainer (D) from the guide pin. Pull the pin through the center of the wheel. Tilt the retainer down and through the center wheel opening. Make sure the retainer is fully seated across the underside of the wheel.
4. Insert the hoist end (F) through the hole (G) in the rear bumper and onto the hoist shaft. Do not use the chiseled end of the wheel wrench. 5. Raise the tire part way upward. Make sure the retainer is seated in the wheel opening. 6. Raise the tire fully against the underside of the vehicle by turning the wheel wrench clockwise until you hear two clicks or feel it skip twice. You cannot overtighten the cable. 7. Make sure the tire is stored securely. Push, pull (A), and then try to turn (B) the tire.
To store the jack and jack tools: 1. Put the tools (D) in the tool bag (E) and place them in the retaining bracket (C). 2. Tighten down the wing nut (C). 3. Assemble the wheel blocks (B) and jack (G) together with the wing nut (A) and retaining bolt (H). 4. Position the jack (G) in the mounting bracket (F). Position the holes in the base of the jack (G) onto the pin in the mounting bracket (F). 5. Return them to their original location in the vehicle.
Spare Tire Your vehicle, when new, had a fully-inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 5-73 and Loading the Vehicle on page 4-32 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-98 and Storing a Flat or Spare Tire and Tools on page 5-108.
Appearance Care Interior Cleaning The vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on the upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from the upholstery. It is important to keep the upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible.
Do not clean the vehicle using: • A knife or any other sharp object to remove a soil from any interior surface. • A stiff brush. It can cause damage to the vehicle’s interior surfaces. • Heavy pressure or aggressive rubbing with a cleaning cloth. Use of heavy pressure can damage the interior and does not improve the effectiveness of soil removal. • Laundry detergents or dishwashing soaps with degreasers can leave residue that streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.
If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness first. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet. Leather A soft cloth dampened with water can be used to remove dust.
Care of Safety Belts Washing Your Vehicle Keep belts clean and dry. The best way to preserve the vehicle’s finish is to keep it clean by washing it often. { CAUTION: Notice: Certain cleaners contain chemicals that can damage the emblems or nameplates on the vehicle. Check the cleaning product label. If it states that it should not be used on plastic parts, do not use it on the vehicle or damage may occur and it would not be covered by the warranty. Do not bleach or dye safety belts.
Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter the vehicle. Avoid using high pressure washes closer than 12 inches (30 cm) to the surface of the vehicle. Use of power washers exceeding 1,200 psi (8 274 kPa) can result in damage or removal of paint and decals. Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses.
Windshield and Wiper Blades Clean the outside of the windshield with glass cleaner. Aluminum or Chrome-Plated Wheels and Trim Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer fluid or a mild detergent. Wash the windshield thoroughly when cleaning the blades. Bugs, road grime, sap, and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged.
The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because they could damage the surface. Do not use chrome polish on aluminum wheels. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by the vehicle warranty. Use chrome polish on chrome wheels only.
Finish Damage 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. Minor chips and scratches can be repaired with touch-up materials available from your dealer/retailer. Larger areas of finish damage can be corrected in your dealer’s/retailer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody.

Services Not Included in Roadside Assistance • Impound towing caused by violation of any laws. • Legal fines. • Mounting, dismounting or changing of snow tires, chains, or other traction devices.
Scheduling Service Appointments When your vehicle requires warranty service, contact your dealer/retailer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer/retailer can help minimize your inconvenience. If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety-related.
Public Transportation or Fuel Reimbursement It may not be possible to provide a like-vehicle as a courtesy rental. If your vehicle requires overnight warranty repairs, and public transportation is used instead of the dealer’s shuttle service, the expense must be supported by original receipts and can only be up to the maximum amount allowed by GM for shuttle service. In addition, for U.S.
Collision Parts Repair Facility 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. Genuine GM Collision parts are your best choice to ensure that your vehicle’s designed appearance, durability, and safety are preserved. The use of Genuine GM parts can help maintain your GM New Vehicle Warranty.
If a Crash Occurs Here is what to do if you are involved in a crash. • Check to make sure that you are all right. If you are uninjured, make sure that no one else in your vehicle, or the other vehicle, is injured. • If there has been an injury, call emergency services for help. Do not leave the scene of a crash until all matters have been taken care of. Move your vehicle only if its position puts you in danger or you are instructed to move it by a police officer.
Managing the Vehicle Damage Repair Process Reporting Safety Defects 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.
Reporting Safety Defects to the Canadian Government Service Publications Ordering Information If you live in Canada, and you believe that your vehicle has a safety defect, notify Transport Canada immediately, in addition to notifying General Motors of Canada Limited.
