Front Seats Manual Seats {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving. If your vehicle has a manual bucket or a split bench seat, you can adjust it with this lever located at the front of the seat. Lift the lever to unlock the seat.
Power Seats If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats. • Raise or lower the front of the seat cushion by raising or lowering the forward edge of the horizontal control. • Move the seat forward or rearward by moving the whole horizontal control forward or rearward. • Raise or lower the rear of the seat cushion by raising or lowering the rear edge of the horizontal control.
Power Lumbar You can increase or decrease lumbar support in an area of the lower seatback. To increase support, press and hold the front of the control. To decrease support, press and hold the rear of the control. Let go of the control when the lower seatback reaches the desired level of support. You can also reshape the side wing area of the lower seatback for more lateral support. To increase support, press and hold the top of the control. To decrease support, press and hold the bottom of the control.
Heated Seats Reclining Seatbacks If your vehicle has this feature, the button used to control the driver’s heated seat is located on the driver’s door panel. The button used to control the passenger’s heated seat is located on the passenger’s door panel. To heat the entire seat, press the horizontal button. Press the button to cycle through the temperature settings of high, medium, and low. The indicator light will glow to indicate the level of heat selected.
{CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this. The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
Head Restraints The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forward and rearward. Seatback Latches {CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. The seatbacks fold forward to let you access the rear of the cab.
Rear Seats Rear Seat Operation (Extended Cab) Folding the Rear Seat The extended cab’s rear seat can be folded up to provide more cargo space. To fold the seat do the following: 1. Pull forward on the release strap located under the rear seat cushion. The extended cab’s rear seat can also be folded open for more seating space. To use the seat do the following: 1. Push rearward on the seat cushion while pulling up on the release strap under the seat cushion. Pull the seat cushion downward until it latches.
To fold the rear seat, do the following: 1. Pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up and fold it forward. To return the seat to the passenger position do the following: 1. Lift the seatback up and push it rearward all the way. 2. Lower the seat cushion until it latches into position. 3. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place.
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. {CAUTION: Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed.
A few crashes are mild, and some crashes can be so serious that even buckled up, a person wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter... a lot! Take the simplest vehicle.
Put someone on it. Get it up to speed. Then stop the vehicle. The rider doesn’t stop.
The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-14 or the instrument panel...
Questions and Answers About Safety Belts Q: Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? A: You could be – whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.
Q: If I’m 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’re in an accident – even one that isn’t your fault – you and your passengers can be hurt. Being a good driver doesn’t 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).
3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 4. 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 isn’t long enough, see Safety Belt Extender on page 1-32.
5. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest.
Q: What’s wrong with this? {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. A: The shoulder belt is too loose. It won’t give nearly as much protection this way.
Q: What’s wrong with this? {CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: 1-20 The belt is buckled in the wrong place.
Q: What’s 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 at the abdomen, not at 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’s 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 aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: 1-22 The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What’s wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn’t 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 to fix it. A: The belt is twisted across the body.
Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.
The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly. Center Passenger Position Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see Driver Position on page 1-16.
Lap Belt When you sit in a center rear seat position of an extended cab or in the center front seat position of either a crew cab or an extended cab or regular cab, you have a lap belt. To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap-shoulder belt. If the belt isn’t long enough, see Safety Belt Extender on page 1-32. Your lap safety belt has no retractor.
Rear Seat Passengers Lap-Shoulder Belt It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Here’s how to wear a lap-shoulder belt properly. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.
2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 1-32. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 3.
The safety belt locks if there’s a sudden stop or a crash. The safety belt also locks if you pull the belt very quickly out of the retractor. {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones.
Rear Safety Belt Comfort Guides for Children and Small Adults Rear seat comfort guides provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head. There is one guide for each outside passenger in the rear seat. Here’s how to install a comfort guide and use the safety belt: 1. Remove the guide from its storage clip on the interior body.
2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt.
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. The extender will be just for you, and just for the seat in your vehicle that you choose. Don’t let someone else use it, and use it only for the seat it is made to fit.
Child Restraints Older Children Q: A: What is the proper way to wear safety belts? If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
{CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. 1-34 Q: What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck? A: If the child is sitting in a rear outside seat position, move the child toward the center of the vehicle.
{CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs.
Every time infants and young children ride in vehicles, they should have the protection provided by appropriate restraints. Young children should not use the vehicle’s adult safety belts alone, unless there is no other choice. Instead, they need to use a child restraint. 1-36 {CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it.
{CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap-shoulder belts offer outstanding protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide.
For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.
Child Restraint Systems An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface. Make sure that the infant’s head rests toward the center of the vehicle. A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint.
A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. 1-40 A booster seat (F-G) is a child restraint designed to improve the fit of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a five-point harness. A booster seat can also help a child to see out the window.
Q: How do child restraints work? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint.
Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors recommends that child restraints be secured in a rear seat including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat.
Do not use child restraints in the center front seat position. The restraints will not work properly. Wherever you install it, be sure to secure the child restraint properly. There is limited space in the rear seating area of an extended cab model.
In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. Raise the head restraint and route the top strap under it.
Top Strap Anchor Location Right Front Passenger Position Top Strap Anchor (Regular and Extended Models) If your vehicle is a crew cab model, a child restraint with a top strap should only be used in the second row. Do not use a child restraint with a top strap in the right front passenger position because there is no place to anchor the top strap. For regular and extended cab models, you will find the top strap anchor for the right front passenger seat behind the seat, near the floor.
Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say. anchors, each seating position has a fabric loop at the top of the seatback that you’ll use to route a top strap through. Rear Seat Top Strap Anchors (Extended Cab Models) If your vehicle is an extended cab model, you’ll find the top strap anchors for the rear seating positions near the top of the seatback.
Rear Seat Top Strap Anchors (Crew Cab Models) When using a child restraint with a top strap in the center rear position, route the top strap through the fabric loop on the seatback. Then, raise the head restraint and attach the top strap to the anchor point located at the closest outboard position. Once you have the top strap anchored, you’ll be ready to secure the child restrain itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.
In order to get to the brackets, you’ll have to remove the trim plugs covering them. There are also anchorage points at the rear base of the front passenger’s seat. Lower Anchorages and Top Tethers for Children (LATCH System) 1-48 Your vehicle has the LATCH system. You will find anchors (A) for the front passenger and the center rear seating positions for extended cab models. For regular cab models, you will find anchors for the right front passenger seating position.
In order to use the LATCH system in your vehicle, you need a child restraint designed for that system.
To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a visible metal anchor point in the seat where the seatback meets the seat cushion. {CAUTION: If a LATCH-type child restraint is not attached to its anchorage points, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed.
Securing a Child Restraint Designed for the LATCH System (Front) Your vehicle has a right front passenger air bag. There is a switch on the instrument panel that you can use to turn off the right front passenger’s frontal air bag. See the following illustration. Your switch may vary slightly. See Air Bag Off Switch on page 1-76 for more on this, including important safety information and illustrations of alternate switch designs.
Never put a rear facing child restraint in the right front passenger’s seat unless the air bag is off. Here is why: {CAUTION: In addition to the air bag off switch, your vehicle may have the passenger sensing system. The passenger sensing system is designed to turn off the right front passenger’s frontal air bag when an infant or small child in a rear-facing infant seat, a forward-facing child restraint, or a booster seat is detected.
{CAUTION: If the air bag readiness light in the instrument panel cluster ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off. If this ever happens, have the vehicle serviced promptly.
6. Push and pull the child restraint in different directions to be sure it is secure. 7. If your vehicle has the passenger sensing system and the air bag is off, the off indicator will be lit and stay lit in the inside rearview mirror when the key is turned to RUN or START. Never put a rear-facing child restraint in the right front passenger seat unless the air bag is off. If a child restraint has been installed and the on indicator is lit, turn the vehicle off.
{CAUTION: If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identified by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inflate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See ″Air Bag Off Switch″ in the Index for more on this, including important safety information.
If your child restraint is equipped with the LATCH system, see Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-48. See Top Strap on page 1-43 if the child restraint has one. If your child restraint does not have the LATCH system, you’ll be using the lap-shoulder belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1.
4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6. Push and pull the restraint in different directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. Securing a Child Restraint in a Center Rear Seat Position Crew Cab When you secure a child restraint in the center rear seat position of a crew cab, you’ll be using a lap-shoulder belt that works the same way as the safety belts in the rear outside seat positions.
1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt. 2. Put the restraint on the seat. 3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
5. To tighten the belt, pull its free end while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push the child restraint as you tighten the belt. Securing a Child Restraint in the Center Front Seat Position 6. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt.
Securing a Child Restraint in the Right Front Seat Position (Crew Cab) A rear seat is a safer place to secure a forward-facing child restraint. If you need to secure a forward-facing child restraint in the right front seat position, see Where to Put the Restraint on page 1-42. If your child restraint is equipped with the LATCH system, see Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-48. See Top Strap on page 1-43 if your child restraint has one.
4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 1-62 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. You should not be able to pull more of the belt out of the retractor once the lock has been set. 7. Push and pull the child restraint in different directions to be sure it is secure.
Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) Your vehicle has a right front passenger air bag. There is a switch on the instrument panel that you can use to turn off the right front passenger’s frontal air bag. See the following illustration. Your switch may vary slightly. See Air Bag Off Switch on page 1-76 for more on this, including important safety information and illustrations of alternate switch designs.
Never put a rear facing child restraint in the right front passenger’s seat unless the air bag is off. Here is why: {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure the air bag is off before using a rear-facing child restraint in the right front seat position.
A rear seat is a safer place to secure a forward facing child restraint. See Where to Put the Restraint on page 1-42. If you need to secure a forward-facing child restraint in the right front seat position, move the seat as far back as it will go before securing a forward-facing child restraint. See Manual Seats on page 1-3 or Power Seats on page 1-4.
3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
8. If your vehicle has the passenger sensing system and the air bag is off, the off indicator will be lit and stay lit in the inside rearview mirror when the key is turned to RUN or START. Never put a rear-facing child restraint in the right front passenger seat unless the air bag is off. If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint.
{CAUTION: If the air bag ON indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal air bag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag.
Air Bag Systems CAUTION: (Continued) This part explains the air bag system. Your vehicle has air bags – one air bag for the driver and another air bag for the right front passenger. Frontal air bags are designed to help reduce the risk of injury from the force of an inflating frontal air bag. But these air bags must inflate very quickly to do their job and comply with federal regulations.
CAUTION: {CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with air bags. The driver should sit as far back as possible while still maintaining control of the vehicle. (Continued) not for young children and infants.
Where Are the Air Bags? The right front passenger’s air bag is in the instrument panel on the passenger’s side. The driver’s air bag is in the middle of the steering wheel.
{CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering. When Should an Air Bag Inflate? An air bag is designed to inflate in a moderate to severe frontal, or near-frontal crash.
Dual Stage Air Bags Single Stage Air Bags If your vehicle has frontal air bags with dual stage deployment, the amount of restraint will adjust according to crash severity. For moderate frontal impacts, these air bags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs.
How Does an Air Bag Restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. Air bags supplement the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
In many crashes severe enough to inflate the air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. • Air bags are designed to inflate only once. After they inflate, you will need some new parts for your air bag system. If you do not get them, the air bag system will not be there to help protect you in another crash. A new system will include air bag modules and possibly other parts.
United States with Passenger Sensing System United States without Passenger Sensing System 1-77
Canada with Passenger Sensing System Canada without Passenger Sensing System This switch should only be turned to AIR BAG OFF if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Infant.
• the infant has a medical condition which, according to the infant’s physician, makes it necessary for the infant to ride in the front seat so that the driver can constantly monitor the child’s condition. Child age 1 to 12.
To turn off the right front passenger’s air bag, insert your ignition key into the switch, push in, and move the switch to the off position. The AIR BAG OFF light will come on to let you know that the right front passenger’s air bag is off. The right front passenger’s air bag will remain off until you turn it back on again, and the AIR BAG OFF light will stay on to remind you that the air bag is off.
To turn the right front passenger’s air bag on again, insert your ignition key into the switch, push in, and move the switch to the ON or AUTO position. Passenger Sensing System United States with Passenger Sensing System United States without Passenger Sensing System Canada with Passenger Sensing System Canada without Passenger Sensing System If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system.
The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the passenger’s frontal air bag should be enabled (may inflate) or not. Passenger Air Bag Status Indicator – United States Passenger Air Bag Status Indicator − Canada The passenger sensing system will turn off the right front passenger’s frontal air bag under certain conditions.
{CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure the air bag is off before using a rear-facing child restraint in the right front seat position.
If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint following the child restraint manufacturer’s directions and refer to Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) on page 1-64 or Securing a Child Restraint Designed for the LATCH System (Front) on page 1-51.
CAUTION: (Continued) vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the frontal air bag. See “Air Bag Readiness Light” in the Index for more on this, including important safety information. Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system.
Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see Service Publications Ordering Information on page 7-12.
Q: What if I added a snow plow? Will it keep the air bags from working properly? A: We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But don’t change or defeat the snow plow’s ″tripping mechanism.″ If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation. Q: Because I have a disability, I have to get my vehicle modified.
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.

Keys {CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. They could operate the power windows or other controls or even make the vehicle move. The children or others could be badly injured or even killed. Do not leave the keys in a vehicle with children.
Your vehicle has one double-sided key for the ignition and all door locks as well as the spare tire hoist lock, if equipped. Remote Keyless Entry System If equipped, the remote keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause interference, and 2.
At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: • Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather. • Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again.
Remote Alarm Battery Replacement When the panic button with the horn symbol on the keyless entry transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the panic button again, waiting for 30 seconds, or starting the vehicle. Under normal use, the battery in your remote keyless entry transmitter should last about two years.
To replace the battery in the keyless entry transmitter do the following: Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.
Doors and Locks Door Locks {CAUTION: Unlocked doors can be dangerous. • Passengers — especially children — can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. You increase the chance of being thrown out of the vehicle in a crash if the doors are not locked. So, wear safety belts properly and lock the doors whenever you drive. • Young children who get into unlocked vehicles may be unable to get out.
Power Door Locks If your vehicle has this power door lock switch, press the raised side of the switch, with the lock symbol, on either front door to lock all the doors at once.

To engage the lock-out feature press the switch, and an indicator light on the switch will illuminate.
Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. Content Theft-Deterrent Your vehicle may be equipped with a content theft-deterrent alarm system. With this system, the security light will flash as you open the door, with the ignition off, to let you know that you are activating the system.
If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power. Remember, the theft-deterrent system won’t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter.
Passlock® Your vehicle is equipped with the Passlock® theft-deterrent system. Passlock® is a passive theft-deterrent system. Passlock® enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.
Ignition Positions With the key in the ignition switch, you can turn it to four different positions. {CAUTION: On manual transmission vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to OFF. Do not press the key release button while the vehicle is moving.
Key Release Button (Manual Transmission) The ignition key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used. Retained Accessory Power (RAP) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 10 minutes after the ignition key is turned to OFF. Your radio, power windows and overhead console will work when the ignition key is in RUN or ACCESSORY.
Manual Transmission The gear selector should be in neutral and the parking brake engaged. Hold the clutch pedal to the floor and start the engine. Your vehicle won’t start if the clutch pedal is not all the way down – that’s a safety feature. Starting Your V8 Engine 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.
Engine Coolant Heater In very cold weather, 0°F (−18°C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle. At temperatures above 32°F (0°C), use of the coolant heater is not required. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord.
How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you’ll be parking your vehicle. The dealer can give you the best advice for that particular area.
{CAUTION: If you have four-wheel drive, your vehicle will be free to roll — even if your shift lever is in PARK (P) — if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear, two-wheel high (2H) or four-wheel high (4H) or four-wheel low (4L) — not in NEUTRAL. See Shifting Into Park (P) on page 2-49 REVERSE (R): Use this gear to back up. If your vehicle is equipped with the Allison Transmission®, the R may blink on the PRNDL if the shift inhibitor is active.
DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: • Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. • Going about 35 mph (55 km/h) or more, push the accelerator all the way down. You’ll shift down to the next gear and have more power. Drive (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving.
Tow/Haul Mode (Automatic Transmission) Overdrive Disable (Allison Transmission®) Your vehicle may be equipped with a Tow/Haul mode. The selector button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load.

For high-speed wiping, turn the band further, to the second solid band past the delay settings. To stop the wipers, move the band to off. 1 (High Speed): For high-speed wiping, turn the band further, to the second solid band past the delay settings. 9(Off): To stop the wipers, move the band to off. Be sure to clear ice and snow from the wiper blades before using them.
Cruise Control 9(Off): This position turns the system off. {CAUTION: Cruise control can be dangerous where you can not drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. R(On): This position activates the system.
Setting Cruise Control {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Move the cruise control switch to on. 2. Get up to the speed you want. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal.
Increasing Speed While Using Cruise Control Passing Another Vehicle While Using Cruise Control There are two ways to go to a higher speed: Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier. • Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You’ll now cruise at the higher speed.
Ending Cruise Control Exterior Lamps There are four ways to turn off the cruise control: • • • • Step lightly on the brake pedal, move the cruise control switch to off, or shift the transmission to NEUTRAL (N). If your vehicle has the Stabilitrak® feature, cruise control will turn off if road conditions cause Stabilitrak® to activate. • If the accelerator pedal is held for 60 seconds or longer, cruise control will turn off.
; (Parking Lamps): Turning the control to this position turns on the parking lamps, together with the following: • • • • • Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights Roof Marker Lamps, if equipped Automatic Headlamp System When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim.
If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See “Instrument Panel Brightness Control” under Interior Lamps on page 3-19.
To idle an automatic transmission equipped vehicle with the DRL off, set the parking brake. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off. The DRL will stay off until you release the parking brake or shift the transmission out of PARK (P). To idle a manual transmission equipped vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake.
Auxiliary Roof Mounted Lamp Switch If your vehicle has this feature, this switch includes wiring provisions for a dealer or a qualified service center to install an auxiliary roof lamp. Cargo Lamp The cargo lamp button is located on the left side of the instrument panel. This switch is located on the center of the instrument panel near the comfort controls. Press the button to turn the cargo lamp on. Press the button again to turn it off.
Interior Lamps Entry Lighting Instrument Panel Brightness Control Your vehicle is equipped with an illuminated entry feature. D: When a door is opened, the dome lamps will come on if the dome override button is in the out position. If the dome override button is pressed in, the lamps will not come on. This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the headlamp control.
Dome Lamps Accessory Power Outlets The dome lamps will come on when you open a door. With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. You can also turn the dome lamps on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the dome lamps will remain on whether the doors are opened or closed.
Notice: Improper use of the power outlet can cause damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Climate Controls Climate Control System Ashtrays and Cigarette Lighter Your vehicle may be equipped with a front ashtray located near the center of the instrument panel. Pull on the door to open it.
Temperature Knob The middle knob on the control panel lets you select the temperature of the air flowing into the passenger area. Turn the knob clockwise toward the red area for warmer air. Turn the knob counterclockwise toward the blue area for cooler air. Mode Knob 1 (Defrost): This setting directs most air through the windshield defroster outlets, side window defroster outlets and some through the floor outlets.
Turn the right knob clockwise or counterclockwise to direct the airflow inside of your vehicle. To change the current mode, select one of the following: H (Vent): This mode directs air to the instrument panel vents. )(Bi-Level): This mode directs half of the air to the instrument panel vents; then directs most of the remaining air to the floor vents. A little air is directed toward the windshield and the side window vents. Cooler air is directed to the upper vents and warmer air to the floor vents.
Defogging and Defrosting Rear Window Defogger Fog on the inside of the windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to choose from to clear fog or frost from your windshield. Use the defog mode to clear the windows of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the windshield more quickly.
Outlet Adjustment Use the air outlets located in the center and on the side of your instrument panel to direct the airflow. Operation Tips • Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. • Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle.
Dual Automatic Climate Control System With this system, you can control the heating, cooling and ventilation in your vehicle. Your vehicle also has a flow-through ventilation system described later in this section. Driver’s Side Temperature Knob The driver’s side knob is used to adjust the temperature of the air coming through the system on the driver’s side. The temperature can be adjusted even if the system is turned off.
The passenger’s temperature setting can be set to match the driver’s temperature setting by pressing and holding the AUTO button for four seconds. Both the driver and passenger arrows will be displayed. Automatic Operation AUTO (Automatic): When automatic operation is active the system will control the inside temperature, the air delivery, and the fan speed. Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button.
To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on the engine coolant temperature. Pressing the fan switch will override this delay and change the fan to a selected speed. 9(Off): Press this button to turn off the entire climate control system. Outside air will still enter the vehicle, and will be directed to the floor. This direction can be changed by pressing the mode button.
@(Recirculation): Press this button to limit the amount of outside air entering your vehicle. The light on the recirculation button will glow. This is helpful when you are trying to limit odors entering your vehicle and for maximum air conditioning performance in hot weather. Press this button again to allow outside air to enter the vehicle. The light on the recirculation button will go off. Pressing this button also cancels the auto recirculation feature.
Whenever you press AUTO, the display will change to show the following: • The current driver’s set temperature and an arrow for five seconds • The current passenger’s set temperature setting and an arrow for five seconds • The automatic air delivery mode and fan speed If the driver’s and passenger’s temperature settings are the same when AUTO is pressed, the temperature setting and both arrows will be displayed for five seconds along with the automatic air delivery mode and fan speed.
On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. On cool, but sunny days while using manual operation of the automatic system, use bi-level to deliver warm air to the floor and cooler air to the instrument panel outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting.
Rear Window Defogger If your vehicle has this feature, the lines you see on the rear window warm the glass. The rear window defogger uses a warming grid to remove fog from the rear window. Outlet Adjustment Use the air outlets located in the center and on the side of your instrument panel to direct the airflow. <(Rear): Press this button to turn the rear window defogger on or off. An indicator light in the button will come on to let you know that the rear window defogger is activated.
Operation Tips • Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. • Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. • Adding outside equipment to the front of your vehicle, such as hood-air deflectors, etc., may affect the performance of the heating and air conditioning system.
Instrument Panel Cluster Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re going, about how much fuel you have and many other things you’ll need to know to drive safely and economically. United States Heavy Duty Automatic Transmission version shown. Canada, Light Duty Automatic and Manual Transmission Clusters similar.
Speedometer and Odometer Engine Hour Meter Display Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). The odometer can also display the number of hours the engine has run. To display the hour meter, turn the ignition off, press and hold the reset button for at least four seconds.
Safety Belt Reminder Light Air Bag Readiness Light When the key is turned to RUN or START, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled. There is an air bag readiness light on the instrument panel cluster, which shows the air bag symbol. The system checks the air bag’s electrical system for malfunctions. The light tells you if there is an electrical problem.
Air Bag Off Light When you turn the right front passenger’s air bag off, this light will be lit and stay lit to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See Air Bag Off Switch on page 1-76 for more on this, including important safety information. The AIR BAG OFF light will look like one of the following illustrations.
Canada with Passenger Sensing System 3-38 Canada without Passenger Sensing System
{CAUTION: {CAUTION: If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identified by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inflate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See ″Air Bag Off Switch″ in the Index for more on this, including important safety information.
Passenger Air Bag Status Indicator If your vehicle has the passenger sensing system your rearview mirror will have a passenger air bag status indicator. the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger’s frontal air bag. If the word ON or the on symbol is lit on the passenger air bag status indicator, it means that the right front passenger’s frontal air bag is enabled (may inflate).
If the word OFF or the off symbol is lit on the passenger air bag status indicator, it means that the passenger sensing system or the air bag off switch has turned off the right front passenger’s air bag. See Passenger Sensing System on page 1-81 or Air Bag Off Switch on page 1-76 for more on this, including important safety information.
Battery Warning Light If this light is displayed when the engine is running, you may have a problem with your charging system. Voltmeter Gage When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts. The battery display will also stay on while the key is in RUN until the engine is started. If the light stays on after starting the engine it could indicate a problem with the generator drive belt, or some other charging system problem.
You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Up-Shift Light This light is used on some models with manual transmissions. Brake System Warning Light With the ignition on, the brake system warning light will flash when you set the parking brake.
{CAUTION: United States Canada This light should come on briefly when you turn the ignition key to RUN. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the floor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-53.
Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem. If the light stays on, or comes on when you’re driving, your vehicle needs service. You will also hear a chime sound when the light is on steady.
The traction off light may come on for the following reasons: • If you turn the system off by pressing the TAS on/off button located to the left of the steering wheel, the light will come on and stay on. To turn the system back on, press the button again; the light should go off. • If you move the shift lever to FIRST (1), the light will come on and stay on to indicate that the traction system is off. This is normal operation.
It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250°F (122°C) mark. If the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 5-36.
If your vehicle has an Allison transmission, and the fluid reaches temperatures of approximately 275°F (135°C) or greater, the driver information center will display a TRANS HOT IDLE ENGINE warning message and a chime will sound until the temperature falls below 265°F (129°C). Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 265°F (129°C).
Malfunction Indicator Lamp Check Engine Light Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems. This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The Check Engine light comes on to indicate that there is a problem and service is required.
This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: • Light Flashing — A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required.
Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-4. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on.
Oil Pressure Gage {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).
Cruise Control Light Tow/Haul Mode Light The cruise light comes on whenever you set your cruise control. See “Cruise Control” under Turn Signal/Multifunction Lever on page 3-7. Four-Wheel-Drive Light The four-wheel drive indicator will light up when you shift a manual transfer case into four-wheel drive and the front axle engages. Some delay between shifting and the indicator’s lighting is normal. This light is displayed when the Tow/Haul mode has been activated.
Fuel Gage Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. • At the gas station, the fuel pump shuts off before the gage reads full. • It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank. • The gage goes back to empty when you turn off the ignition.

Your Driving, the Road, and Your Vehicle Defensive Driving The best advice anyone can give about driving is: Drive defensively. proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do things like this, or pull off the road in a safe place to do them yourself. These simple defensive driving techniques could save your life. Drunken Driving Please start with a very important safety device in your vehicle: Buckle up.
Many adults — by some estimates, nearly half the adult population — choose never to drink alcohol, so they never drive after drinking. For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological and developmental reasons for these laws. same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin or vodka.
There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight will when each has the same number of drinks. The law in an increasing number of U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany.
Control of a Vehicle {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. Please 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. You have three systems that make your vehicle go where you want it to go.
Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Also see Traction Assist System (TAS) on page 4-9. Braking Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That is perception time. Then you have to bring up your foot and do it. That is reaction time. Average reaction time is about 3/4 of a second.
Anti-lock Brake System Your vehicle has anti-lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid. When you start your engine and begin to drive away, your anti-lock brake system will check itself. You may hear a momentary motor or clicking noise while this test is going on. This is normal. If there is a problem with the anti-lock brake system, this warning light will stay on. See Anti-Lock Brake System Warning Light on page 3-45.
The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Remember: Anti-lock does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops.
Traction Assist System (TAS) Your vehicle may have a Traction Assist System (TAS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power to limit wheel spin. The traction control system is enabled every time your vehicle is started.
• A Traction Assist System, Anti-Lock Brake System or engine-related problem has been detected and the vehicle needs service. • If the vehicle has been driven with the TAS system on for long periods of time, or if the vehicle has gone through many several high speed braking maneuvers the system may be automatically disabled. The system will automatically re-enable after approximately two minutes of not using the brakes. See Traction Off Light on page 3-45.
The next time you start your vehicle, the TAS will not automatically come on. You can restore the automatic feature by repeating the same procedure. Whether the TAS is set to come on automatically or not, you can always turn the system on or off by pressing the TAS on/off button. Manual Selectable Ride The main function of this system is to provide superior ride comfort while trailering or fully loaded, as well as for unloaded driving.
FIRM (Loaded): Press the button to activate this setting, the indicator light will be lit. Use this setting to minimize trailer inputs to the vehicle or when the vehicle is fully loaded. This setting is also appropriate for off-road driving. You can select a setting at any time based on road and trailering conditions to provide the best ride and handling. Select a new setting whenever driving conditions change.
What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you will want to go slower. See Braking on page 4-6. It is better to remove as much speed as you can from a possible collision.
QUADRASTEER™ The QUADRASTEER™ System has a control and diagnostic module that monitors and records current system status and operational information. If your vehicle is equipped with the 4 Wheel Steer system it has the ability to steer the vehicle with all four wheels. Once the 4 Wheel Steer mode is selected, it is recommended to leave the vehicle in this mode at all times, and during all driving and weather conditions.
4: In this mode all four wheels will help steer the vehicle. If you want to use 4, and your vehicle is not in this mode, press the button, until the 4 indicator, located to the right of the 4 Wheel Steer button, comes on and stays on. If the 4 indicator is flashing you will have to center the steering wheel by turning it to the left or right. Higher Speeds (40 m.p.h./64 km/h, and above) At higher speeds the front and rear wheels will turn in the same direction.
To engage the 4 Wheel Steer tow mode, press the button until the 4 and tow mode indicators light up on the instrument panel. If the tow indicator is flashing you will have to center the steering wheel by turning it to the left or right. While in the 4 wheel steer tow mode, it is possible the steering wheel may be slightly off center. For more information, see Towing a Trailer on page 4-70.
Off-Road Recovery Passing You may find that your right wheels have dropped off the edge of a road onto the shoulder while you are driving. The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again.
• Do not get too close to the vehicle you want to pass while you are awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you are following a larger vehicle. Also, you will not have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance. • When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and do not get too close.
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 your vehicle’s three control systems. In the braking skid, your 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.
Off-Road Driving with Your Four-Wheel-Drive Vehicle This off-road guide is for vehicles that have four-wheel drive. Also, see Braking on page 4-6. If your vehicle does not have four-wheel drive, you should not drive off-road unless you are on a level, solid surface. Off-road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. “Off-roading” means you have left the great North American road system behind. Traffic lanes are not marked.
The front bumper lower air dam is held in place by a series of push-pins located around the lower edge of the front bumper. The push-pins are accessible from underneath the front bumper. The following steps must be performed on each of the push-pins to remove the air dam: 1. Insert a tool into the push-pin slot and pull downward until the push-pin snaps loose. 2.
When you are back on roads, though, be sure to replace the air dam. Notice: Operating your vehicle for extended periods without the front bumper lower air dam installed can cause improper air flow to the engine and may allow things like fog lamps or tow hooks on the front of your vehicle to be damaged. Always be sure to replace the front bumper air dam when you are finished off-road driving. 2. Push the flat end of the push-pin toward the retainer until it locks into place, making sure each is secure.
Loading Your Vehicle for Off-Road Driving There are some important things to remember about how to load your vehicle. {CAUTION: • Cargo on the load floor piled higher than • The heaviest things should be on the load floor and forward of your rear axle. Put heavier items as far forward as you can. • Be sure the load is secured properly, so driving on the off-road terrain does not toss things around. • • the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured.
Environmental Concerns Traveling to Remote Areas Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GM recognizes these concerns and urge every off-roader to follow these basic rules for protecting the environment: It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain.
Controlling your vehicle is the key to successful off-road driving. One of the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds: • you approach things faster and you have less time to scan the terrain for obstacles. • you have less time to react. • you have more vehicle bounce when you drive over obstacles. • you will need more distance for braking, especially since you are on an unpaved surface.
When you drive over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs or other surface features can jerk the wheel out of your hands if you are not prepared. When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground. If this happens, even with one or two wheels, you can not control the vehicle as well or at all. Because you will be on an unpaved surface, it is especially important to avoid sudden acceleration, sudden turns or sudden braking.
Approaching a Hill When you approach a hill, you need to decide if it is one of those hills that is just too steep to climb, descend or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top. On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs.
Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. • Use a low gear and get a firm grip on the steering wheel. • Get a smooth start up the hill and try to maintain your speed. Do not use more power than you need, because you do not want your wheels to start spinning or sliding. • Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route.
Q: What should I do if my vehicle stalls, or is about to stall, and I can not make it up the hill? A: If this happens, there are some things you should do, and there are some things you must not do. First, here is what you should do: • Push the brake pedal to stop the vehicle and keep • As you are backing down the hill, put your left hand on the steering wheel at the 12 o’clock position. This way, you will be able to tell if your wheels are straight and maneuver as you back down.
Q: Suppose, after stalling, I try to back down the hill and decide I just can not do it. What should I do? A: 4-30 Set the parking brake, put your transmission in PARK (P), or the manual transmission in FIRST (1), and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. Do not shift the transfer case to NEUTRAL when you leave the vehicle. Leave it in some gear.
Driving Downhill When off-roading takes you downhill, you will want to consider a number of things: • How steep is the downhill? Will I be able to maintain vehicle control? • What is the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? • Are there hidden surface obstacles? Ruts? Logs? Boulders? {CAUTION: Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and a serious accident.
• Never go downhill with the transmission in NEUTRAL (N), or with the clutch pedal pressed down in a manual shift. This is called “free-wheeling.” Your brakes will have to do all the work and could overheat and fade. Q: Am I likely to stall when going downhill? A: It is much more likely to happen going uphill. But if it happens going downhill, here is what to do. • Stop your vehicle by applying the regular brakes. Apply the parking brake.
For reasons like these, you need to decide carefully whether to try to drive across an incline. Just because the trail goes across the incline does not mean you have to drive it. The last vehicle to try it might have rolled over. {CAUTION: Driving across an incline that is too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, do not drive across it. Find another route instead.
Stalling on an Incline If your vehicle stalls when you are crossing an incline, be sure you (and your passengers) get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts to roll over, you will be right in its path. If you have to walk down the slope, stay out of the path the vehicle will take if it does roll over. 4-34 {CAUTION: Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous.
Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels will not get good traction. You can not accelerate as quickly, turning is more difficult, and you will need longer braking distances. It is best to use a low gear when you are in mud — the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you do not get stuck. {CAUTION: Driving on frozen lakes, ponds or rivers can be dangerous.
Driving in Water Heavy rain can mean flash flooding, and flood waters demand extreme caution. Find out how deep the water is before you drive through it. If it is deep enough to cover your wheel hubs, axles or exhaust pipe, do not try it — you probably will not get through. Also, water that deep can damage your axle and other vehicle parts. If the water is not too deep, drive slowly through it. At faster speeds, water splashes on your ignition system and your vehicle can stall.
After Off-Road Driving Driving at Night Remove any brush or debris that has collected on the underbody, chassis or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage.
Here are some tips on night driving. • Drive defensively. • Do not drink and drive. • Adjust your inside rearview mirror to reduce the glare from headlamps behind you. • Since you can not see as well, you may need to slow down and keep more space between you and other vehicles. • Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead. • In remote areas, watch for animals. • If you are tired, pull off the road in a safe place and rest.
Driving in Rain and on Wet Roads The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking. It is wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid.
Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can not, try to slow down before you hit them. {CAUTION: Wet brakes can cause accidents. They will not work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally.
Driving Through Flowing Water Some Other Rainy Weather Tips • Turn on your low-beam headlamps – not just your {CAUTION: • Flowing or rushing water creates strong forces. If you try to drive through flowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of flowing water can carry away a smaller vehicle. If this happens, you and other vehicle occupants could drown.
City Driving Here are ways to increase your safety in city driving: • Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. • Try to use the freeways that rim and crisscross most large cities. You will save time and energy. See Freeway Driving on page 4-43. • Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it.
Freeway Driving At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the flow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic flow.
Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are. Before Leaving on a Long Trip Make sure you are ready. Try to be well rested. If you must start when you are not fresh — such as after a day’s work — do not plan to make too many miles that first part of the journey. Wear comfortable clothing and shoes you can easily drive in.
Then here are some tips: Hill and Mountain Roads • Make sure your vehicle is well ventilated, with a comfortably cool interior. • Keep your eyes moving. Scan the road ahead and to the sides. Check your mirrors and your instruments frequently. • If you get sleepy, pull off the road into a rest, service or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency.
If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable. See Off-Road Driving with Your Four-Wheel-Drive Vehicle on page 4-20 for information about driving off-road. • Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads. • Know how to go down hills.
• You may see highway signs on mountains that warn of special problems. Examples are long grades, passing or no-passing zones, a falling rocks area or winding roads. Be alert to these and take appropriate action. Winter Driving Here are some tips for winter driving: • Have your vehicle in good shape for winter. • You may want to put winter emergency supplies in your vehicle.
Whatever the condition — smooth ice, packed, blowing or loose snow — drive with caution. If you have traction assist, keep the system on. It will improve your ability to accelerate when driving on a slippery road. But you can turn the traction system off if your vehicle ever gets stuck in sand, mud, ice or snow. See If You Are Stuck: In Sand, Mud, Ice or Snow on page 4-51. Even though your vehicle has a traction system, you will want to slow down and adjust your driving to the road conditions.
Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti-lock braking system, you will want to begin stopping sooner than you would on dry pavement. See Braking on page 4-6. If You Are Caught in a Blizzard • Allow greater following distance on any slippery road. • Watch for slippery spots. The road might be fine until you hit a spot that is covered with ice.
• Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats — anything you can wrap around yourself or tuck under your clothing to keep warm. {CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can not see it or smell it, so you might not know it is in your vehicle.
Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.
Rocking Your Vehicle To Get It Out Using the Recovery Hooks First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four-wheel-drive vehicle, shift into 4HI. If your vehicle has the Traction Assist System, you should turn it off by pressing the TAS on/off button. Then shift back and forth between REVERSE (R) and a forward gear (or with a manual transmission, between FIRST (1) or SECOND (2) and REVERSE (R)), spinning the wheels as little as possible.
Notice: Never use recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty. Towing Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-6. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as dinghy towing, towing your vehicle will all four wheels on the ground, and dolly towing, towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”.
Four-Wheel-Drive Vehicles Equipped with Transfer Case (NP1, NP2 and NP8) Use the following procedure to tow your vehicle: 1. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 2. Turn the engine off, but leave the ignition on. 3. Firmly set the parking brake. 4. Securely attach the vehicle being towed to the tow vehicle. 5. Shift the transfer case to NEUTRAL. See Four-Wheel Drive on page 2-35 for the proper procedure to select the neutral position for your vehicle. 6.
Dolly Towing Four-Wheel-Drive Vehicles Use the following procedure to tow your vehicle: 1. Drive the vehicle up onto the tow dolly. 2. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 3. Turn the engine off, but leave the ignition on. 4. Firmly set the parking brake. 5. Securely attach the vehicle being towed to the tow dolly. {CAUTION: Two-Wheel-Drive Vehicles Two-wheel-drive vehicles should not be towed with the rear wheels on the ground.
6. Shift the transfer case to NEUTRAL. See Four-Wheel Drive on page 2-35 for the proper procedure to select the neutral position for your vehicle. 7. Release the parking brake only after the vehicle being towed is firmly attached to the towing vehicle. 8. Turn the ignition off and lock the steering column. Loading Your Vehicle {CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR.
Tire and Loading Information Label The Tire and Loading Information label also tells you the size and recommended inflation pressure for the original equipment tires on your vehicle.
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.
Example 2 Example 3 Loading Your Vehicle Loading Your Vehicle Item Description Item Description A Vehicle Capacity Weight for Example 2 = 1,000 lbs (453 kg) Total A Vehicle Capacity Weight for Example 3 = 1,000 lbs (453 kg) Total B Subtract Occupant Weight 150 lbs (68 kg) x 5 = 750 lbs (340 kg) B Subtract Occupant Weight 200 lbs (91 kg) x 5 = 1,000 lbs (453 kg) C Available Cargo Weight = 250 lbs. (113 kg) C Available Cargo Weight = 0 lbs.
Certification/Tire Label 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: {CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. 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.
Payload Payload capacity is the maximum load capacity that your vehicle can carry. Be sure to include the weight of the occupants as part of your load. If you added any accessories or equipment after your vehicle left the factory, remember to subtract the weight of these things from the payload. Your dealer can help you with this. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle.
Adding a Snow Plow or Similar Equipment Before installing a snow plow on your vehicle, here are some things you will need to know: Notice: If your vehicle does not have the snow plow prep package, adding a plow can damage your vehicle, and the repairs would not be covered by warranty. Unless your vehicle was built to carry a snow plow, do not add one to your vehicle.
Here are some guidelines for safely carrying a snow plow on your vehicle: • Make sure the weight on the front and rear axles does not exceed the axle rating for each. • For the front axle, if more cargo or passengers must be carried, appropriate counter ballast must be installed rear of the rear axle. Counter ballast must be properly secured so it will not move during driving. • Follow the snow plow manufacturer’s recommendations regarding rear ballast.
In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula: For example, adding a 700 lb. (318 kg) snow plow actually adds more than 700 lb. (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 lb.
{CAUTION: On some vehicles equipped with certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front GAWR but not have enough weight on the rear axle to have proper braking performance. If your brakes can not work properly, you could have a crash.
Truck-Camper Loading Information This label is inside your glove box. It will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out your load. Also, it will help you match the right slide-in camper to your vehicle.
Here is an example of proper truck and camper match: Your dealer can help you make a good vehicle-camper match. He’ll also help you determine your CWR. After you’ve loaded your vehicle and camper, drive to a weigh station and weigh the front and rear wheels separately. This will tell you the loads on your axles. The loads on the front and rear axles shouldn’t be more than either of the GAWRs. The total of the axle loads should not be more than the GVWR.
Trailer Recommendations You must subtract your hitch loads from the CWR for your vehicle. Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the spring bars in place. You’ll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes. For more information, see Towing a Trailer on page 4-70.
To identify the vehicle trailering capacity of your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. • Don’t tow a trailer at all during the first 500 miles If yours was built with trailering options, as many are, it’s ready for heavier trailers. But trailering is different than just driving your vehicle by itself. Trailering means changes in acceleration, braking, handling, durability and fuel economy.
Tow/Haul Mode Tow/Haul is a feature on automatic transmission equipped vehicles that assists when pulling a heavy trailer or a large or heavy load. The purpose of the Tow/Haul mode is to: • Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load.
Weight of the Trailer How heavy can a trailer safely be? It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. Use one of the following charts to determine how much your vehicle can weigh, based upon your vehicle model and options.

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. If you have a lot of options, equipment, passengers or cargo in your vehicle, it will reduce the tongue weight your vehicle can carry, which will also reduce the trailer weight your vehicle can tow.
Fifth wheel or gooseneck kingpin weight should be 15 to 25 percent of the trailer weight up to the maximum amount specified in the trailering chart for your vehicle. See “Weight of theTrailer”, and “Fifth-Wheel and Gooseneck Trailering” in this section. Do not exceed the maximum allowable tongue weight for your vehicle. Choose the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the rear axle.
Weight Distributing Hitches and Weight Carrying Hitches When using a weight-distributing hitch, the hitch must be adjusted so the distance (A) remains the same both before and after coupling the trailer to the tow vehicle. If you use a step-bumper hitch, the bumper could be damaged in sharp turns. Make sure there is ample room when turning to avoid contact between the trailer and the bumper.
Fifth Wheel and Gooseneck Trailering Safety Chains Fifth wheel and gooseneck trailers can be used with many pickup models. These trailers place a larger percentage of the weight (kingpin weight) on the tow vehicle than conventional trailers. Make sure this weight does not cause the vehicle to exceed GAWR or GVWR. You should always attach chains between your vehicle and your trailer.
Trailer Brakes If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes – and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Your trailer brake system can tap into the vehicle’s hydraulic brake system only if: • The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. • The trailer’s brake system will use less than 0.02 cubic inch (0.
Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself 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 a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment.
Turn Signals When Towing a Trailer The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not.
Parking on Hills {CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet for an automatic transmission, or into gear for a manual transmission. 2. Have someone place chocks under the trailer wheels. 3.
When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: • Start your engine • Shift into a gear • Release the parking brake Trailer Wiring Harness Your vehicle is equipped with one of the following wiring harnesses for towing a trailer or hauling a slide-in camper. Basic Trailer Wiring All regular, extended cab crew cab pickups have a six-wire trailer towing harness. 2. Let up on the brake pedal. 3.
The six-wire harness contains the following trailer circuits: • • • • • • Yellow: Left Stop/Turn Signal Heavy-DutyTrailer Wiring Harness Package Dark Green: Right Stop/Turn Signal Brown: Taillamps White: Ground Light Green: Back-up Lamps Light Blue: Center High-Mounted Stoplamp (CHMSL) If you need to upgrade your trailer wiring harness, an additional 2–wire harness and 7 pin universal trailer connector are available from your dealer.
The eight-wire harness contains the following trailer circuits: • • • • • • • • Yellow: Left Stop/Turn Signal Dark Green: Right Stop/Turn Signal Brown: Taillamps White: Ground Light Green: Back-up Lamps Light Blue: CHMSL Red: Battery Feed Dark Blue: Trailer Brake If your trailer is equipped with electric brakes, you can get a jumper harness (electric trailer brake control) with a trailer battery feed fuse from your dealer.
Instrument Panel Jumper Wiring Harness {CAUTION: If your vehicle is equipped with the “Heavy-Duty Trailering″ option, please refer to Heavy-Duty Trailer Wiring Package, earlier in this section. When the camper-wiring harness is ordered without the heavy-duty trailering package, an eight-wire harness with a seven-pin connector and separate CHMSL connector are located at the rear of the vehicle and are tied to the vehicle’s frame.
Four-Wire Harness Adapter This adapter is included with your vehicle as part of the heavy-duty trailer wiring package. This harness is included with your vehicle as part of the heavy-duty trailer wiring package. Use this adapter to connect a standard four-way round pin connector to the seven-wire harness on your vehicle. This harness is for an electric brake controller and includes a trailer battery feed fuse. It should be installed by your dealer or a qualified service center.
If your vehicle has this provision, this relay will be located on the passenger’s side of the vehicle, next to the auxiliary battery. Connect the adapter with the tab pointing up (see arrow). The flip cap on the vehicle’s seven-wire harness will lock onto the tab and help hold the adapter in place. Plug the four-way round pin connector onto the adapter.
Power Winches If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored. Power Take-Off (PTO) Before using a PTO, if equipped, refer to the manufacturer’s or installer’s instructions. To engage a PTO on a vehicle with a manual transmission do the following: 1. Hold the clutch pedal down. 2. Set the parking brake. 3. Shift the transmission into NEUTRAL (N). 4. Engage the PTO.
Preset Mode: PTO speed control mode is used for stationary applications. (PTO will remain engaged while mobile in the preset mode, however PTO set and resume speed controls will be inoperative). This mode provides a default standby speed of 800 or 850 rpm (depending on the engine/transmission combination) and two default PTO control speeds which follow: 1. PTO Set Speed of 1,250 rpm, or 2. PTO Resume Speed of 1,700 rpm.
All engine speed values listed above are factory preset values. With the exception of the TCC lockup speed (1,100 rpm) and the “tap″ increment (100 rpm), all of these values are programmable and can be adjusted by your dealer or body upfitter. If the PTO software settings do not match the settings shown here, then they may have already been altered in order to satisfy the requirements of the installed PTO system and body equipment. When the PTO switch is turned on, the engine is limited to 2200 rpms.

Service Doing Your Own Service Work Your dealer knows your vehicle best and wants you to be happy with it. We hope you will go to your dealer for all your service needs. You will get genuine GM parts and GM-trained and supported service people. If you want to do some of your own service work, you will want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can.
CAUTION: (Continued) • Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt. Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle.
Gasoline Specifications California Fuel It is recommended that gasoline meet specifications which were developed by automobile manufacturers around the world and contained in the World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org. Gasoline meeting these specifications could provide improved driveability and emission control system performance compared to other gasoline.
Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations.
Filling Your Tank {CAUTION: While refueling, hang the fuel cap by the tether using the hook located on the inside of the filler door. 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 your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, flames and smoking materials away from fuel.
To remove the fuel cap, turn it slowly to the left (counterclockwise). It will require more effort to turn the fuel cap on the last turn as you loosen it. {CAUTION: If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.
Filling a Portable Fuel Container {CAUTION: If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. Notice: If you need a new fuel cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system.
Checking Things Under the Hood {CAUTION: Things that burn can get on hot engine parts and start a fire. These include liquids like fuel, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine. 5-10 Hood Release To open the hood do the following: 1. Pull the handle inside the vehicle located under and to the left of the steering wheel.
2. Then go to the front of the vehicle and pull up on the secondary hood release located near the center of the grill. 3. Lift the hood. Before closing the hood, be sure all filler caps are on properly. Pull down the hood and close it firmly.

Engine Oil If your vehicle has a diesel engine, see “Engine Oil” in the Diesel Engine Supplement. If the CHECK OIL LEVEL light appears on the instrument cluster (except vehicles equipped with the 4.3L engine), it means you need to check your engine oil level right away. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.
When to Add Engine Oil See Engine Compartment Overview on page 5-12 for the location of the engine oil fill cap. If the oil is at or below the cross-hatched area at the tip of the dipstick, then you will need to add at least one quart of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-134. Notice: Do not add too much oil.
• SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, if it is going to be 0°F (–18°C) or above and SAE 5W-30 is not available, you may use SAE 10W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also 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. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM Goodwrench® oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil.
How to Reset the CHANGE ENGINE OIL Message The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system.
Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-12 for location of engine air cleaner/filter and change indicator (if equipped). How to Inspect Locate the filter change indicator. When the change indicator turns black or is in the red/orange “change” zone, replace the filter and reset the indicator. To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake filter to release loose dust and dirt.
{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 flame 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. 1. Loosen the screws on the cover of the housing and lift up the cover. 2. Remove the air cleaner/filter from the housing.
Automatic Transmission Fluid (Except Allison Transmission®) How to Check When to Check and Change Because this operation can be a little difficult, you may choose to have this done at the dealership service department. A good time to check your automatic transmission fluid level is when the engine oil is changed. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it’s colder than 50°F (10°C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more.
See Engine Compartment Overview on page 5-12 for more information on location. 1. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds and then pull it back out again. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Recommended Fluids and Lubricants on page 6-14. Add fluid only after checking the transmission fluid while it is hot.
Automatic Transmission Fluid (Allison Transmission®) How to Check When to Check and Change Because this operation can be a little difficult, you may choose to have this done at the dealership service department. A good time to check your automatic transmission fluid level is when the engine oil is changed. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
Checking the Fluid Level Prepare your vehicle as follows: • Park your vehicle on a level place. Keep the engine running. • With the parking brake applied, place the shift lever in PARK (P). • With your foot on the brake pedal, run the engine for at least once minute and shift to DRIVE (D). Then shift to NEUTRAL (N) and then REVERSE (R) to fill the hydraulic system. Then, position the shift lever in PARK (P). • Allow the engine to run at idle (500–800 rpm). Slowly release the brake pedal.
4. Safe operating level is within the HOT RUN band on the dipstick. The width of the HOT RUN band represents approximately 1.06 quart (1.0 liter) of fluid at normal operating temperature. 5. If the fluid level is not within the HOT RUN band, add or drain fluid as necessary to bring the fluid level to within the HOT RUN band. 6. If the fluid level is in the acceptable range, push the dipstick back in all the way.
Manual Transmission Fluid Then, follow these steps: When to Check A good time to have it checked is when the engine oil is changed. See your maintenance schedule to find out when to change your transmission fluid. How to Check Because this operation can be a little difficult, you may choose to have this done at your GM dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading.
How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See Recommended Fluids and Lubricants on page 6-14. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole. 3. Install the filler plug. Be sure the plug is fully seated.
How to Check and Add Fluid The proper fluid should be added if the level does not reach the bottom of the diaphragm when it’s in place in the reservoir. See the instructions on the reservoir cap. Engine Coolant The cooling system in your vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL® extended life coolant.
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else. {CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant The coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FULL COLD mark. If your vehicle is equipped with a low coolant sensor, and the LOW COOLANT LEVEL message comes on and stays on, it means you’re low on engine coolant.
Coolant Surge Tank Pressure Cap See Engine Compartment Overview on page 5-12 for more information on location. Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 3-46. In addition, you will find a ENGINE OVERHEATED and a REDUCED ENGINE POWER message in the Driver Information Center on the instrument panel. See Driver Information Center (DIC) on page 3-55.
If Steam Is Coming From Your Engine CAUTION: (Continued) down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See “Overheated Engine Protection Operating Mode” under Engine Overheating on page 5-36 for information on driving to a safe place in an emergency.
If No Steam Is Coming From Your Engine An overheat warning, along with a low coolant condition, can indicate a serious problem. For more information, see Driver Information Center (DIC) on page 3-55. If you get an engine overheat warning and don’t have a low coolant condition, 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.
Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see: All Other Engines 8100 V8 Engines A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap C. Engine Fan If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. The vehicle should be parked on a level surface.
The coolant level should be at or above the FULL COLD mark. If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. {CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned.
How to Add Coolant to the Coolant Surge Tank for Gasoline Engines If you haven’t found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level isn’t at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See Engine Coolant on page 5-33 for more information.
CAUTION: (Continued) vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and a proper coolant. Notice: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.
1. Park the vehicle on a level surface. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. 2. Turn the pressure cap slowly counterclockwise (left) about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 3. Then keep turning the pressure cap slowly, and remove it. 4.
6. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. Engine Fan Noise 5. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark.
Power Steering Fluid All Other Engines 8100 V8 Engine When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. See Engine Compartment Overview on page 5-12 for reservoir location.
How to Check Power Steering Fluid Windshield Washer Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. What to Use The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.
The windshield washer fluid reservoir is located in the engine compartment toward the front of the vehicle on the driver’s side. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. Notice: • When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. • Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system.
Brakes Brake Fluid Your brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 5-12 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system.
Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. If it is not, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark.
What to Add When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See Recommended Fluids and Lubricants on page 6-14. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. {CAUTION: With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.
Brake Wear Your vehicle has four-wheel 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 may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly). Notice: Continuing to drive with worn-out brake pads could result in costly brake repair.
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. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system — for example, when your brake linings wear down and you need new ones put in — be sure you get new approved GM replacement parts. If you do not, your brakes may no longer work properly.
Jump Starting If your battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to follow the steps below to do it safely. {CAUTION: Batteries can hurt you. They can be dangerous because: • They contain acid that can burn you. • They contain gas that can explode or ignite. • They contain enough electricity to burn you. If you do not follow these steps exactly, some or all of these things can hurt you.
3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t 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: {CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. Be sure the battery has enough water. You do not need to add water to the ACDelco® battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there.
5-56 7. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one. 9. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) terminal if the vehicle has one.

Tires CAUTION: Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle’s Owner’s Manual. Poorly maintained and improperly used tires are dangerous. • Overloading your tires can cause overheating as a result of too muchfriction.
(A) Tire Size Code: 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 Code” illustration later in this section for more detail. (B) Tire Performance Criteria Specification (TPC Spec): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall.
(F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. For more information, see Uniform Tire Quality Grading on page 5-90. (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 5-84 and Loading Your Vehicle on page 4-57.
(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. (B) Tire Performance Criteria Specification (TPC Spec): 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.
Tire Size The following examples show the different parts of a tire size. (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 illustration, it would mean that the tire’s sidewall is 75% as high as it is wide. (D) Construction Code: A letter code is used to indicate the type of ply construction in the tire.
(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. (E) Rim Diameter: Diameter of the wheel in inches. Light Truck (LT-Metric) Tire (A) Light Truck (LT-Metric) Tire: The United States version of a metric tire sizing system.
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. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread.
Normal Occupant Weight: The number of occupants a vehicle is designed to seat multiplied by 150 pounds (68 kg). See Loading Your Vehicle on page 4-57. Occupant Distribution: Designated seating positions. Outward Facing Sidewall: The side of a asymmetrical tire that has a particular side that faces outward when mounted on a vehicle.
Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs. (68 kg) plus the rated cargo load. See Loading Your Vehicle on page 4-57. Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the original equipment tire size and recommended inflation pressure. See Loading Your Vehicle on page 4-57.
When to Check Dual Tire Operation Check your tires once a month or more. 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 Flat Tire and Installing the Spare Tire” in the index. Also, check the tire pressure of the spare tire. How to Check Use a good quality pocket-type gage to check tire pressure.
Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-88 and Wheel Replacement on page 5-92 for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench/hoist shaft to tighten the cable.
If your vehicle has dual rear wheels and the tread design for your front tires is the same as your rear tires, always use one of the correct rotation patterns shown here when rotating your tires. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label or Tire and Loading Information label. See Loading Your Vehicle on page 4-57. Make certain that all wheel nuts are properly tightened.
When It Is Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will 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. 5-88 You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire’s rubber.
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label or the Tire and Loading Information label. See Loading Your Vehicle on page 4-57, for more information about these labels and where they can be found on your vehicle. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specifications (TPC Spec) number on each tire’s sidewall. When you get new tires, GM recommends that you get tires with that same TPC Spec number.
{CAUTION: If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width.
Traction – AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.
Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need.
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. Whenever a wheel, wheel bolt or wheel nut is replaced on a dual wheel setup, 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, see “Wheel Nut Torque” under Capacities and Specifications on page 5-134.
Tire Chains CAUTION: {CAUTION: If your vehicle has dual wheels or P265/75R16, LT265/75R16 or P265/70R17 size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Tire chains used on a vehicle without the properamount of clearance can cause damage to thebrakes, suspension or other vehicle parts. Thearea 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’s unusual for a tire to “blowout” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s 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 will create 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 your hazard warning flashers. {CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3.
The following steps will tell you how to use the jack and change a tire.
For regular cab models, the equipment you’ll need is behind the passenger’s seat. For Extended and crew cab models, the equipment is on the shelf behind the passenger’s side second row seat. 1. If there is a cover, move the seats forward and turn the wing nut on the cover counterclockwise to remove it. For crew cab models, pull up the second row seat with the loop at the base of the seat cushion to access the tools. 2.
1. If your vehicle is equipped with a hoist lock (J), open the spare tire lock cover on the bumper and use the ignition key to remove the lock. 2. Assemble the wheel wrench (H) and the two jack handle extensions (I) as shown. A. Spare Tire (Valve Stem Pointed Down) B. Hoist Assembly C. Hoist Cable D. Tire Retainer E. Hoist Shaft F. Hoist End of Extension Tool G. Hoist Shaft Access Hole H. Wheel Wrench I. Jack Handle Extensions J.
3. Insert the hoist end (open end) (F) of the extension through the hole (G) in the rear bumper. Be sure the hoist end of the extension connects to the hoist shaft (E). The ribbed square end of the extension is used to lower the spare tire. 4. Turn the wheel wrench (H) counterclockwise to lower the spare tire to the ground. Continue to turn the wheel wrench until the spare tire can be pulled out from under the vehicle.
Removing the Flat Tire and Installing the Spare Tire Use the following pictures and instructions to remove the flat tire and raise the vehicle. 1. Remove the center cap by placing the chisel end of the wheel wrench in the slot on the wheel and gently prying the cap out. The tools you’ll be using include the bottle jack (A), the wheel blocks (B), the jack handle (C), the jack handle extensions (D), and the wheel wrench (E).
Jacking Locations 2. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts. Don’t remove the wheel nuts yet. Notice: If your vehicle has QUADRASTEER™ and you use a jack to raise the vehicle without positioning it correctly, you could damage the QUADRASTEER™ system. When raising your vehicle on a jack, avoid contact with tie rods and tie rod boots. 5-102 A. Front Location (2-Wheel Drive 1500 Series) B. Front Location (All Other Series) C.
{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. {CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.
Front Position All Other Models Rear Position 4. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. 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.
5. Remove all the wheel nuts and take off the flat tire. 6. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. {CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle.
7. After mounting the spare, put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the nuts until the wheel is held against the hub.
Front Position 2WD 1500 Series Rear Position 5-107
8. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely. CAUTION: (Continued) nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See “Capacities and Specifications” in the Index for wheel nut torque specification. 9. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise.
Storing a Flat or Spare Tire, Jack 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 may damage the wheel.
To store the jack and jack tools do the following: 1. Put the jack tools and gloves in the tool bag and place in the retaining bracket. Tighten down the wing nut. Store the tire under the rear of the vehicle in the spare tire carrier. Use the art and text following to help you: 2. Assemble the wheel blocks and bottle jack together with the wing nut and retaining hook. 3. Position the jack in the mounting bracket. Position the holes in the base of the jack onto the pin in the mounting bracket. A.
1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down, and to the rear. 2. Tilt the retainer (D) downward and through the 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 into the hoist shaft. 5. Raise the tire part way upward. Make sure the retainer is seated in the wheel opening. 6.
Secondary Latch System Your vehicle has an underbody mounted tire hoist assembly equipped with a secondary latch system. It’s 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, Jack and Tools” earlier in this section. {CAUTION: A. Push and Pull B. Rotate Tire 7. Make sure the tire is stored securely. Push, pull, and then try to rotate or turn the tire.
To release the spare tire from the secondary latch do the following: 4. Repeat this procedure at least two times. If the spare tire lowers to the ground, continue with Step 5 of “Removing the Spare Tire and Tools” earlier in this section. 5. Turn the wrench counterclockwise until approximately six inches (15 cm) of cable is exposed. 6. Stand the wheel blocks on their shortest ends, with the backs facing each other. 1. Check under the vehicle to see if the cable end is visible. 2.
8. Attach the jack handle, extension, and wheel wrench to the jack and place it (with the wheel blocks) under the vehicle towards the front of the rear bumper. Position the center lift point of the jack under the center of the spare tire. 9. Turn the wrench clockwise to raise the jack until it lifts the end fitting. 10. Continue raising the jack until the spare tire stops moving upward and is held firmly in place. The secondary latch has released and the spare tire is balancing on the jack.
11. Lower the jack by turning the wheel wrench counterclockwise. Keep lowering the jack until the spare tire slides off the jack or is hanging by the cable. {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 the spare. 12. Disconnect the jack handle from the jack and carefully remove the jack.
Spare Tire Appearance Care 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 5-84 and Loading Your Vehicle on page 4-57 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Changing a Flat Tire on page 5-96. Remember, cleaning products can be hazardous. Some are toxic.
Do not use any of these unless this manual says you can. In many uses, these will damage your vehicle: • • • • Alcohol Laundry Soap Bleach Reducing Agents Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfaces with a clean, damp cloth. • Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.
Special Fabric Cleaning Problems Cleaning Vinyl Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: Use warm water and a clean cloth. 1. Carefully scrape off excess stain, then sponge the soiled area with cool water. 2. If a stain remains, follow the cleaning instructions described earlier. 3.

Maintenance Schedule Introduction Important: Keep engine oil at the proper level and change as recommended. Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance may not be covered by warranty.
Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary.
Owner Checks and Services on page 6-10 tells you what should be checked, when to check it and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, fluids and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-14 and Normal Maintenance Replacement Parts on page 6-17. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle.

Customer Assistance and Information Customer Satisfaction Procedure Your satisfaction and goodwill are important to your dealer and to GMC. Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur.
STEP THREE: Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you should file with the BBB Auto Line Program to enforce any additional rights you may have. Canadian owners refer to your Warranty and Owner Assistance Information booklet for information on the Canadian Motor Vehicle Arbitration Plan (CAMVAP).

Please refer to the Warranty and Owner Assistance Information book.
Plan Ahead When Possible Shuttle Service When your vehicle requires warranty service, you should contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. Participating dealers can provide you with shuttle service to get you to your destination with minimal interruption of your daily schedule.
Courtesy Rental Vehicle Your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle you obrtained if your vehicle is kept for a warranty repair. Reimbursement will be limited to a maximum of $30.00 a day and must be supported by receipts. This requires that you sign and complete a rental agreement and meet state, local and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc.
Vehicle Data Collection and Event Data Records Your vehicle, like other modern motor vehicles, has a number of sophisticated computer systems that monitor and control several aspects of the vehicle’s performance. Your vehicle uses on-board vehicle computers to monitor emission control components to optimize fuel economy, to monitor conditions for airbag deployment and, if so equipped, to provide anti-lock braking and to help the driver control the vehicle in difficult driving situations.
Reporting Safety Defects Reporting Safety Defects to the United States Government If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA), in addition to notifying General Motors. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign.
