Front Seats Manual Seats {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver’s seat only when the vehicle is not moving. Lift the bar located under the front of the seat to unlock it. Slide the seat to where you want it and release the bar. Try to move the seat with your body to be sure the seat is locked in place.
Power Seat To raise or lower the seat, move the center knob up or down. To move the seat forward or rearward, move the center knob toward the right or left. To raise or lower the front of the seat cushion, move the right lever up or down. To raise or lower the rear of the seat cushion, move the left lever up or down. If your vehicle has front power seat(s), you can adjust them with these controls located at the front center of the seat cushion.
Reclining Seatbacks The seats have manual reclining seatbacks. The lever used to operate them is located on the inboard side of the seats. {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver’s seat only when the vehicle is not moving.
To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked. {CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job because it will not be against your body.
Rear Seats Rear Seat Operation 2. Locate the pins. On a three passenger seat there are two pins located on the inboard sides of the rear seats. Removing the Rear Seat Disconnect the quick release latch plates for the lap-shoulder belts on the bench seat to be removed. 1. To do this, press the tip of a key into the release hole of the safety belt buckle while pulling up on the safety belt. Three Passenger Seat Shown The driver’s side pin has a gray cap with a black “L” marked on it.
3. Pull the pin handle up to disengage the pin from the retaining clip, then pull the pin out. 4. Repeat this procedure for the other pins. 5. Pull the seat rearward about 2 inches (5 cm) and then lift the seat from the floor rails. 6. Remove the seat from the vehicle. 7. For the first row rear seat, stow the safety belt latch by attaching the clip on the safety belt latch to the trim just inside the side door.
Replacing the Rear Seats {CAUTION: A seat that is not locked into place properly can move around in a collision or sudden stop. People in the vehicle could be injured. Be sure to lock the seat into place properly when installing it. {CAUTION: A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured.
Three Passenger Seat Shown 4. Push the pin(s) marked “R” down until they are in the retaining clip. Three Passenger Seat Shown 5. Push the pin(s) marked “L” down until they are in the retaining clip. 6. If the vehicle has a floor mat, put the flap back to its original position. 7. Repeat this procedure for the other seat base. 8. Connect the quick-release latch plates for the lap-shoulder belts by inserting the latch plates into the buckles attached at the outboard positions of the bench seat.
Safety Belts {CAUTION: Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. {CAUTION: Do not let anyone ride where he or she cannot wear a safety belt properly. If you are in a crash and you are not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle harder or be ejected from it and be seriously injured or killed.
Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it is just a seat on wheels.
Get it up to speed. Then stop the vehicle. The rider does not stop. 1-12 The person keeps going until stopped by something. In a real vehicle, it could be the windshield...
or the instrument panel... or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense.
Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after a crash if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle a safety belt, even if you are upside down.
How to Wear Safety Belts Properly This section is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see Older Children on page 1-29 or Infants and Young Children on page 1-32. Follow those rules for everyone’s protection. It is very important for all occupants to buckle up.
Q: What is wrong with this? {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit snugly against your body. A: The shoulder belt is too loose. It will not give as much protection this way.
Q: What is wrong with this? {CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force on your abdomen. This could cause serious or even fatal injuries. The lap belt should be worn low and snug on the hips, just touching the thighs. A: The lap belt is too loose. It will not give nearly as much protection this way.
Q: What is wrong with this? {CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not on the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place.
Q: What is wrong with this? {CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied on the abdomen, not on the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. A: The belt is over an armrest.
Q: What is wrong with this? {CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. The shoulder belt should go over the shoulder and across the chest. A: The shoulder belt is worn under the arm.
Q: What is wrong with this? {CAUTION: You can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, you would not be restrained by the shoulder belt. Your body could move too far forward increasing the chance of head and neck injury. You might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest. A: The belt is behind the body.
Q: What is wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer/retailer to fix it. Lap-Shoulder Belt All seating positions in your vehicle have a lap-shoulder belt.
If you ever pull the shoulder portion of a passenger belt out all the way, you may engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again. 3. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 1-28. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary.
Shoulder Belt Height Adjuster Your vehicle has a shoulder belt height adjuster for the driver and right front passenger position. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. To unlatch the belt, push the button on the buckle. The belt should go back out of the way.
Safety Belt Pretensioners Rear Safety Belt Comfort Guides If the GVWR (Gross Vehicle Weight Rating) of your vehicle is below 8,500 lb (3 855 kg) then your vehicle has safety belt pretensioners for the front occupants. You can find the GVWR on the certification label on the rear edge of the driver’s door. See Loading Your Vehicle on page 4-20 for more information. Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults.
2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 1-26 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
{CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. 4. Buckle, position, and release the safety belt as described in previously in this section. Make sure that the shoulder belt crosses the shoulder.
Safety Belt Use During Pregnancy Safety Belt Extender Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. If the vehicle’s safety belt will fasten around you, you should use it. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy. The best way to protect the fetus is to protect the mother.
Child Restraints Older Children The manufacturer’s instructions that come with the booster seat, state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the below fit test: • Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. • Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue.
Q: What is the proper way to wear safety belts? A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. This applies belt force to the child’s pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
{CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. In a crash, the child would not be restrained by the shoulder belt. The child might slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The child could also move too far forward increasing the chance of head and neck injury. The shoulder belt should go over the shoulder and across the chest.
Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
CAUTION: (Continued) Neither the vehicle’s safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide. {CAUTION: Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants.
Q: What are the different types of add-on child restraints? {CAUTION: A: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. For most basic types of child restraints, there are many different models available.
Child Restraint Systems {CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries.
Securing an Add-On Child Restraint in the Vehicle {CAUTION: A booster seat (C-D) is a child restraint designed to improve the fit of the vehicle’s safety belt system. A booster seat can also help a child to see out the window. 1-36 A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle.
To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraint systems must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH) on page 1-39 for more information. A child can be endangered in a crash if the child restraint is not properly secured in the vehicle.
Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We recommend that children and child restraints be secured in a rear seat, including: an infant or a child riding in a rear-facing child restraint; a child riding in a forward-facing child seat; an older child riding in a booster seat; and children, who are large enough, using safety belts. A label on your sun visor says, “Never put a rear-facing child seat in the front.
If your vehicle does not have a rear seat that will accommodate a rear-facing child restraint, we recommend that rear-facing child restraints not be transported in your vehicle, even if the airbag is off. Wherever you install a child restraint, be sure to secure the child restraint properly. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle.
Lower Anchors Top Tether Anchor Lower anchors (A) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (B). A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle.
In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. Be sure to read and follow the instructions for your child restraint. If the child restraint does not have a top tether, one can be obtained, in kit form, for many child restraints. Ask the child restraint manufacturer whether or not a kit is available. Do not install three child restraints in the same row at the same time and never install two top tethers using the same top tether anchor.
The second, third and fourth row with three passenger seats have exposed metal lower anchors located in the crease between the seatback and the seat cushion. Front Passenger Position Second, Third and Fourth Row with Three Passenger Seat — Passenger Van There are two top tether anchors in the second, third and fourth rows. To install a child restraint in the rear driver side seating positions, use anchor point (A).
Securing a Child Restraint Designed for the LATCH System {CAUTION: If a LATCH-type child restraint is not attached to anchors, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchors, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual.
{CAUTION: Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. Secure any unused safety belts behind the child restraint so children cannot reach them. Pull the shoulder belt all the way out of the retractor to set the lock, if your vehicle has one, after the child restraint has been installed. Be sure to follow the instructions of the child restraint manufacturer.
2. If the child restraint manufacturer recommends that the top tether be attached, attach and tighten the top tether to the top tether anchor, if equipped. Refer to the child restraint instructions and the following steps: 2.1. Find the top tether anchor. 2.2. For the second, third and fourth row with three passenger seats only, in the rear driver side seating positions, use anchor point (A). For the rear passenger side seating positions, use anchor point (B).
If the position you are using has an integrated headrest or head restraint and you are using a single tether, route the tether over the headrest or head restraint. 3. Push and pull the child restraint in different directions to be sure it is secure. Securing a Child Restraint in a Rear Seat Position When securing a child restraint in a rear seating position, study the instructions that came with your child restraint to make sure it is compatible with this vehicle.
If you need to install more than one child restraint in the rear seat, be sure to read Where to Put the Restraint on page 1-38. 1. Put the child restraint on the seat. 2. 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. 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 3. Push the latch plate into the buckle until it clicks.
6. If your child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-39 for more information. 7. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle’s safety belt and let it go back all the way. If the top tether is attached to a top tether anchor, disconnect it. 5.
{CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag.
You will be using the lap-shoulder belt to secure the child restraint in this position. Follow the instructions that came with the child restraint. 1. Move the seat as far back as it will go before securing the forward-facing child restraint. When the passenger sensing system has turned off the right front passenger’s frontal airbag, the off indicator in the passenger airbag status indicator should light and stay lit when you start the vehicle. See Passenger Airbag Status Indicator on page 3-30. 2.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, push down on the child restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor. If you are using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
7. If your vehicle does not have a rear seat and your child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-39 for more information. 8. Push and pull the child restraint in different directions to be sure it is secure. If the airbag is off, the off indicator in the passenger airbag status indicator will come on and stay on when the vehicle is started.
{CAUTION: {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger’s airbag could inflate even though the switch is off.
If your child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 1-39 for how to install your child restraint using LATCH. If you secure a child restraint using a safety belt and it uses a top tether, see Lower Anchors and Tethers for Children (LATCH) on page 1-39 for top tether anchor locations.
4. Push the latch plate into the buckle until it clicks. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if necessary. 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
7. If your vehicle does not have a rear seat and your child restraint has a top tether, follow the child restraint manufacturer’s instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH) on page 1-39 for more information. 8. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, unbuckle the vehicle’s safety belt and let it go back all the way.
Airbag System {CAUTION: If the right front passenger’s airbag is turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inflate and help protect the person sitting there. Do not turn off the passenger’s airbag unless the person sitting there is in a risk group identified by the national government.
All of the airbags in your vehicle will have the word AIRBAG embossed in the trim or on an attached label near the deployment opening. For frontal airbags, the word AIRBAG will appear on the middle part of the steering wheel for the driver and on the instrument panel for the right front passenger. With roof-rail airbags, the word AIRBAG will appear along the headliner or trim.
{CAUTION: {CAUTION: Airbags inflate with great force, faster than the blink of an eye. Anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to the airbag, as you would be if you were sitting on the edge of your seat or leaning forward. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with airbags.
Where Are the Airbags? If your vehicle has one, the right front passenger’s airbag is in the instrument panel on the passenger’s side. The driver’s frontal airbag is in the middle of the steering wheel.
Driver Side shown, Passenger Side similar If your vehicle is a cargo or passenger van with a sliding door and it has a roof-rail airbag for the driver and right front passenger position, the roof-rail airbags are in the ceiling above the side window.
For passenger vans with a sliding door, on the passenger’s side of the vehicle, you will have a separate roof-rail airbag for the passenger seated directly behind the right front passenger and the third row outboard passenger position. {CAUTION: If something is between an occupant and an airbag, the airbag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear.
• If the vehicle hits a narrow object (like a pole), the airbags could inflate at a different crash speed than if the vehicle hits a wide object (like a wall). • If the vehicle goes into an object at an angle, the airbags could inflate at a different crash speed than if the vehicle goes straight into the object. Thresholds can also vary with specific vehicle design. Frontal airbags are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts. Single Stage vs.
What Makes an Airbag Inflate? In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover and deploy. The inflator, the airbag, and related hardware are all part of the airbag module. Frontal airbag modules are located inside the steering wheel and instrument panel.
The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle.
Airbag Off Switch If your instrument panel has one of the switches pictured in the following illustrations, your vehicle has an airbag on-off switch that you can use to manually turn on or off the right front passenger’s airbag. This switch should only be turned to airbag 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.
Medical Condition. A passenger has a medical condition which, according to his or her physician: • Causes the passenger airbag to pose a special risk for the passenger; and • Makes the potential harm from the passenger airbag in a crash greater than the potential harm from turning off the airbag and allowing the passenger, even if belted, to hit the dashboard or windshield in a crash.
The airbag off light will come on to let you know that the right front passenger’s airbag is off. The airbag off light will stay on to remind you that the airbag is off. See Airbag Off Light on page 3-28. The airbag off light will stay on to remind you that the airbag is off. The right front passenger’s airbag will remain off until you turn it back on again.
Passenger Sensing System If your instrument panel has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system unless there is an airbag off switch located on the instrument panel. If there is an airbag off switch, your vehicle does not have a passenger sensing system. See Airbag Off Switch on page 1-66 for more information. The words ON and OFF, or the symbol for on and off, will be visible during the system check.
A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag.
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 (With Passenger Sensing System) in the Index.
Restart the vehicle and have the person remain in this position for two to three minutes. This will allow the system to detect that person and then enable the right front passenger’s frontal airbag. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system.
A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment other than any that GM has approved for your specific vehicle. See Adding Equipment to Your Airbag-Equipped Vehicle on page 1-74 for more information about modifications that can affect how the system operates.
Adding Equipment to Your Airbag-Equipped Vehicle Q: Is there anything I might add to or change about the vehicle that could keep the airbags from working properly? A: Yes. If you add things that change your vehicle’s frame, bumper system, height, front end or side sheet metal, they may keep the airbag system from working properly.
Restraint System Check Airbags Checking the Restraint Systems The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light on page 3-27 for more information. Safety Belts Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts.
Replacing Restraint System Parts After a Crash {CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

If you need more power for passing, and you are: • Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down.
SECOND (2): This position reduces vehicle speed even more than THIRD (3) without using your brakes. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. You may use this feature for reducing torque to the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces. FIRST (1): This position reduces vehicle speed even more than SECOND (2) without using your brakes.
While activated, the indicator light on the instrument panel will be on. Parking Brake Tow/haul mode will turn off automatically when the ignition is turned off. See Tow/Haul Mode Light on page 3-40. Tow/haul is most effective when the vehicle and trailer combined weight is at least 75 percent of the vehicle’s Gross Combined Weight Rating (GCWR). See “Weight of the Trailer” later in this section.
If the ignition is on when the parking brake is released, the brake system warning light will go off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Verify that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 4-28. That section shows what to do first to keep the trailer from moving.
Leaving Your Vehicle With the Engine Running {CAUTION: It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave your vehicle with the engine running.
Shifting Out of PARK (P) Your vehicle has an automatic transaxle shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is RUN. See Automatic Transmission Operation on page 2-22. The shift lock control system is designed to do the following: • Prevent the ignition key from being removed unless the shift lever is in PARK (P). If you still are unable to shift out of PARK (P): 1. Ease the pressure on the shift lever. 2.
Engine Exhaust CAUTION: (Continued) {CAUTION: • Your vehicle was damaged when driving Engine exhaust and fuel operated heater exhaust can kill. It contains the gas carbon monoxide (CO), which you cannot see or smell. It can cause unconsciousness and death. If your vehicle has a diesel engine and a fuel operated heater, see “Fuel Operated Heater (FOH)” in the diesel engine supplement. • • You might have exhaust coming in if: • The exhaust system sounds strange or different.
Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust on page 2-30. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is a garage.

Instrument Panel Cluster The instrument panel cluster is designed to let you know at a glance how the vehicle is running. You will know how fast you are going, how much fuel you are using, and many other things you will need to know to drive safely and economically. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information.
Speedometer and Odometer Safety Belt Reminders The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Safety Belt Reminder Light The odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). When the engine is started, 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.
Passenger Safety Belt Reminder Light Airbag Readiness Light Several seconds after the engine is started, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 1-69 for more information. The passenger safety belt light, located on the instrument panel, will come on and stay on for several seconds and then flash for several more.
If the airbag readiness light stays on after you start the vehicle or comes on when you are driving, your airbag system may not work properly. Have your vehicle serviced right away. {CAUTION: If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly. The airbags in your vehicle may not inflate in a crash, or they could even inflate without a crash.
{CAUTION: {CAUTION: If the right front passenger’s airbag is turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inflate and help protect the person sitting there. If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system.
Passenger Airbag Status Indicator If your vehicle has the passenger sensing system, your instrument panel will have a passenger airbag status indicator. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inflate). {CAUTION: United States Canada When you start the vehicle, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check.
{CAUTION: Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off.
Charging System Light This light will come on briefly when you turn on the ignition, but the engine is not running, as a check to show you it is working. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-49 for more information.
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. Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well.
Antilock Brake System Warning Light For vehicles with the Antilock Brake System (ABS), this light will come on briefly when you start the engine. That is normal. If the light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system.
Engine Coolant Temperature Gage Tire Pressure Light This light comes on briefly when the engine is started. United States Canada This gage shows the engine coolant temperature. 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.
Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure 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 an OBD II problem and service is required.
If the Light is Flashing The following can prevent more serious damage to your vehicle: • • • • been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Reduce vehicle speed. Did you just drive through a deep puddle of water? Avoid hard accelerations. If so, your vehicle’s electrical system might be wet.
Emissions Inspection and Maintenance Programs Oil Pressure Gage Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the check engine light is on or not working properly.

Your Driving, the Road, and Your Vehicle Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear your safety belt — See Safety Belts: They Are for Everyone on page 1-10. {CAUTION: Assume that other road users (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready. In addition: • Allow enough following distance between you and the driver in front of you.
Police records show that almost 40 percent of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 17,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with about 250,000 people injured. Control of a Vehicle For persons under 21, it is against the law in every U.S. state to drink alcohol.
And, of course, actual stopping distances vary greatly with the surface of the road, whether it is pavement or gravel; the condition of the road, whether it is wet, dry, or icy; tire tread; the condition of the brakes; the weight of the vehicle; and the amount of brake force applied. Antilock Brake System (ABS) Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake.
ABS can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. As you brake, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance.
Pressing and holding the StabiliTrak® button located on the instrument panel for more than five seconds can turn off StabiliTrak® and part of the traction control system. For more information, see StabiliTrak® Indicator Light on page 3-34. For your safety, the system can only be disabled when the vehicle speed is less than 20 mph (32 km/h). You will hear three chimes and the StabiliTrak® not ready light will come on. To turn on the StabiliTrak® system, press the StabiliTrak® button again.
Traction Control Operation All-Wheel Drive (AWD) System ® The traction control system is part of the StabiliTrak system. Traction control limits wheel spin by reducing engine power to the wheels (engine speed management) and by applying brakes to each individual wheel (brake-traction control) as necessary. If the brake-traction control system activates constantly or if the brakes have heated up due to high speed braking, the brake-traction control will be automatically disabled.
Steering Tips It is important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there is no traction, inertia will keep the vehicle going in the same direction.
Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking — if you can stop in time. But sometimes you cannot; there is not room. That is the time for evasive action — steering around the problem.
Off-Road Recovery Passing You may find that your right wheels have dropped off the edge of a road onto the shoulder while you are driving. Passing another vehicle on a two-lane road can be dangerous. To reduce the risk of danger while passing, we suggest the following tips: • Look down the road, to the sides, and to crossroads for situations that might affect a successful pass. If in doubt, wait. • Watch for traffic signs, pavement markings, and lines that could indicate a turn or an intersection.
Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to your vehicle’s three control systems. In the braking skid, the wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force.
Driving at Night Night driving is more dangerous than day driving because some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue. Night driving tips include: • Drive defensively. • Do not drink and drive. • Reduce headlamp glare by adjusting the inside rearview mirror. • Slow down and keep more space between you and other vehicles because your headlamps can only light up so much road ahead. 4-12 • • • • • Watch for animals. When tired, pull off the road.
Driving in Rain and on Wet Roads Hydroplaning Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water. Hydroplaning is dangerous. Water can build up under your vehicle’s tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough.
Before Leaving on a Long Trip Highway Hypnosis To prepare your vehicle for a long trip, consider having it serviced by your dealer/retailer before departing. Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, find a safe place to park your vehicle and rest.
Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: • Keep your vehicle serviced and in good shape. • Check all fluid levels and brakes, tires, cooling system, and transmission. • Going down steep or long hills, shift to a lower gear. {CAUTION: If you do not shift down, the brakes could get so hot that they would not work well.
Winter Driving Here are some tips for winter driving: • Have your vehicle in good shape for winter. • You might want to put winter emergency supplies in your vehicle. Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and reflective warning triangles.
Whatever the condition — smooth ice, packed, blowing, or loose snow — drive with caution. Accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. The Antilock Brake System (ABS) improves your vehicle’s stability when you make a hard stop on a slippery road. Even though you have ABS, begin stopping sooner than you would on dry pavement. See Antilock Brake System (ABS) on page 4-4.
{CAUTION: You can run the engine to keep warm, but be careful. Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust pipe and/or the fuel operated heater exhaust system, if equipped.
Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery (or batteries) charged. You will need a well-charged battery (or batteries) to restart the vehicle, and possibly for signaling later on with the headlamps. Let the heater run for a while.
Rocking Your Vehicle to Get It Out Loading Your Vehicle First, turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction or stability system. See StabiliTrak® System on page 4-5. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears.
Tire and Loading Information Label The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation see Tires on page 5-53 and Inflation - Tire Pressure on page 5-60. There is also important loading information on the vehicle Certification/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 − 750 (5 x 150) = 650 lbs). 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.
Example 2 Item A B C Description Vehicle Capacity Weight for Example 2 = Subtract Occupant Weight 150 lbs (68 kg) × 5 = Available Cargo Weight = Example 3 Total Item 1,000 lbs (453 kg) A 750 lbs (136 kg) B 250 lbs (113 kg) C Description Vehicle Capacity Weight for Example 3 = Subtract Occupant Weight 200 lbs (91 kg) × 5 = Available Cargo Weight = Total 1,000 lbs (453 kg) 1000 lbs (453 kg) 0 lbs (0 kg) Refer to your vehicle’s tire and loading information label for specific information about you
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.
Add-On Equipment {CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. • Put things in the cargo area of your vehicle. Try to spread the weight evenly. • Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. • Do not leave an unsecured child restraint in your vehicle. • When you carry something inside the vehicle, secure it whenever you can.
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 your vehicle with all four wheels on the ground) and “dolly” (towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”).
Dolly Towing Rear Towing (Rear Wheels Off the Ground) Two-Wheel-Drive Vehicles Use the following procedure to tow your vehicle from the rear: 1. Drive the vehicle onto the dolly. 2. Firmly set the parking brake. See Parking Brake on page 2-26 for more information. 3. Put the automatic transmission in PARK (P). 4. Follow the dolly manufacturer’s instructions to attach and secure the vehicle being towed to the dolly and then the loaded dolly to the tow vehicle. Make sure the wheels are straight before towing.
Towing a Trailer If your vehicle has a diesel engine, see the DURAMAX® Diesel manual for more information. {CAUTION: If you do not use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well — or even at all. You and your passengers could be seriously injured. You may also damage your vehicle; the resulting repairs would not be covered by your warranty.
If You Do Decide To Pull A Trailer If you do, here are some important points: • There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. • Consider using a sway control. See “Hitches” later in this section. • Don’t tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven.
The following charts show how much your trailer can weigh, based upon 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.
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. After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer.
But let’s say your specific vehicle is equipped with some of the latest options and you have a front seat passenger and two rear seat passengers with some luggage and gear in the vehicle as well. You may add 300 lbs (136 kg) to the front axle weight and 400 lbs (181 kg) to the rear axle weight. Your vehicle now weighs: The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you with being able to handle only 600 lbs (272 kg) of tongue weight.
Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the upper limit for cold tires. You’ll find these numbers on the Certification label at the rear edge of the driver’s door or see Loading Your Vehicle on page 4-20. Then be sure you don’t go over the GVW limit for your vehicle, or the GAWR, including the weight of the trailer tongue. If you use a weight distributing hitch, make sure you don’t go over the rear axle limit before you apply the weight distribution spring bars.
If you’ll be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg), be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving. You should always use a sway control if your trailer will weigh more than these limits. You can ask a hitch dealer/retailer about sway controls.
Driving with a Trailer {CAUTION: If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You can not see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-30. To maximize your safety when towing a trailer: • Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip. • Keep the rear-most windows closed.
Passing Turn Signals When Towing a Trailer You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. When you tow a trailer, your vehicle has to have extra wiring and a heavy-duty turn signal (included in the optional trailering package). Backing Up Hold the bottom of the steering wheel with one hand.
When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked (preferably on level ground) with the automatic transmission in PARK (P) for a few minutes before turning the engine off.
Maintenance When Trailer Towing Trailer Wiring Harness Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transmission fluid (don’t overfill), engine oil, axle lubricant, belt, cooling system and brake system.

Service Accessories and Modifications For service and parts needs, visit your dealer/retailer. You will receive genuine GM parts and GM-trained and supported service people. When non-dealer/non-retailer accessories are added to your vehicle they can affect your vehicle’s performance and safety, including such things as, airbags, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control and stability control.
California Perchlorate Materials Requirements Certain types of automotive applications, such as airbag initiators, seat belt pretensioners, and lithium batteries contained in remote keyless entry transmitters, may contain perchlorate materials. Special handling may be necessary. For additional information, see www.dtsc.ca.gov/hazardouswaste/perchlorate.
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 can cause wind noise and can affect fuel economy and windshield washer performance. Check with your dealer/retailer before adding equipment to the outside of your vehicle. Fuel If your vehicle has a diesel engine, see “Diesel Fuel Requirements and Fuel System” in the DURAMAX® Diesel manual. For vehicles with gasoline engines, please read this.
Gasoline Octane California Fuel Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you might notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service.
Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, you should not have to add anything to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations.
Fuel E85 (85% Ethanol) The 8th digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies your vehicle’s engine. The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 5-103. If your vehicle has the 5.3L V8 engine (VIN Code 4 only), you can use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel on page 5-5.
To ensure quick starts in the wintertime, the E85 fuel must be formulated properly for your climate according to ASTM specification D 5798. If you have trouble starting on E85, it could be because the E85 fuel is not properly formulated for your climate. If this happens, switching to gasoline or adding gasoline to the fuel tank can improve starting. For good starting and heater efficiency below 32°F (0°C), the fuel mix in the fuel tank should contain no more than 70% ethanol.
Filling the Tank {CAUTION: Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Do not use cellular phones. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle. This is against the law in some places.
{CAUTION: {CAUTION: Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way. 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.
Filling a Portable Fuel Container Checking Things Under the Hood {CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the fuel vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: • Dispense fuel only into approved containers. • Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed, or on any surface other than the ground.
Hood Release To open the hood: 1. Pull the handle with this symbol on it. It is located in front of the driver’s side door frame near the floor. 2. Then go to the front of the vehicle and lift up the secondary hood release, which is located underneath the middle of the hood. 3. Lift the hood, release the hood prop from its retainer and put the hood prop into the slot in the hood. If your vehicle has an underhood lamp, it will automatically come on and stay on until the hood is closed.
Engine Compartment Overview If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information.
A. Battery. See Battery on page 5-39. B. Radiator Pressure Cap. See Radiator Pressure Cap on page 5-26. C. Coolant Recovery Tank. See Cooling System on page 5-28. D. Automatic Transmission Fluid Dipstick. See “Checking the Fluid Level” under Automatic Transmission Fluid on page 5-20. E. Engine Oil Fill Cap. See “When to Add Engine Oil” under Engine Oil (Gasoline Engine) on page 5-15. F. Engine Oil Dipstick. See “Checking Engine Oil” under Engine Oil (Gasoline Engine) on page 5-15. G.
When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-110. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged.
What Kind of Engine Oil to Use Look for three things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. Look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. • Oils meeting these requirements should have the starburst symbol on the container.
Engine Oil Additives Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you need for good performance and engine protection. Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage.
What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment.
How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. Never use compressed air to clean the filter. To inspect or replace the engine air cleaner/filter, do the following: 1. Unhook the retainer clips and remove the cover. 2. Lift the filter out of the engine air cleaner/filter housing.
When to Check and Change Automatic Transmission Fluid A good time to check your automatic transmission fluid level is when the engine oil is changed. Change the fluid and filter at the intervals listed in Additional Required Services (Gasoline Engine) on page 6-6, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 6-14.
Checking the Fluid Level Prepare your vehicle as follows: 1. Park your vehicle on a level place. Keep the engine running. 2. With the parking brake applied, place the shift lever in PARK (P). See Engine Compartment Overview on page 5-14 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. 3.
How to Add Automatic Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Recommended Fluids and Lubricants on page 6-14. Using a funnel, add fluid down the transmission dipstick tube only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check.
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant which will not damage aluminum parts. If you use this coolant mixture, you do not need to add anything else. {CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant for Gasoline Engines If your vehicle has a diesel engine, see “Checking Coolant” under “Van Models” in the DURAMAX® Diesel Supplement for information on checking your vehicle’s coolant. The coolant recovery tank is located near the center of the engine compartment. See Engine Compartment Overview on page 5-14 for more information on location. {CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly.
Radiator Pressure Cap The radiator pressure cap is located near the center of the engine compartment. See Engine Compartment Overview on page 5-14 for more information on location. Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. Engine Overheating If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information.
If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: • • • • Climb a long hill on a hot day. Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. See “Driving on Grades” under Towing a Trailer on page 4-28.
Cooling System If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. If your vehicle has a diesel engine, see “Van Models” under “Cooling System” in the DURAMAX® Diesel Supplement. When the engine is cold, the coolant level should be at or above the COLD FILL mark. If it is not, 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: (Continued) Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core, or radiator corrosion.
How to Add Coolant to the Coolant Recovery Tank for Gasoline Engines If your vehicle has a diesel engine, see “How to Add Coolant to the Coolant Recovery Tank” under “Van Models” in the Cooling System section of the DURAMAX® Diesel Supplement for the proper coolant fill procedure. If you have not found a problem yet, but the coolant level is not at the COLD FILL mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® engine coolant at the coolant recovery tank.
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. {CAUTION: You can be burned if you spill coolant on hot components in the engine compartment. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine or components in the engine compartment.
How to Add Coolant to the Radiator for Gasoline Engines If your vehicle has a diesel engine, see “How to Add Coolant to the Radiator” under “Van Models” in the Cooling System section of the DURAMAX® Diesel Supplement for the proper radiator fill procedure. 1. You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops.
4. Then fill the coolant recovery tank to the COLD FILL mark. 5. Put the cap back on the coolant recovery tank, but leave the radiator pressure cap off. 6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOL® coolant mixture through the filler neck until the level reaches the base of the filler neck.
Engine Fan Noise Your vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, so you may hear an increase in fan noise.
4. Replace the cap and completely tighten it. Adding Washer Fluid 5. Then remove the cap again and look at the fluid level on the dipstick. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 5-14 for reservoir location. The level should be at the COLD FILL mark. If necessary, add only enough fluid to bring the level up to the mark.
Brakes Brake Fluid The brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 5-14 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The 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 hydraulic system.
Checking Brake Fluid The brake fluid can be checked without taking off the cap by looking at the brake fluid reservoir. The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir. {CAUTION: With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash.
Brake Wear Your vehicle has disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal firmly. Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes.
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 brake parts. When you replace parts of the braking system — for example, when the brake linings wear down and you need new ones put in — be sure you get new approved replacement parts. If you do not, the brakes might not work properly.
Jump Starting If your vehicle’s battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. {CAUTION: Batteries can hurt you. They can be dangerous because: • They contain acid that can burn you. • They contain gas that can explode or ignite. • They contain enough electricity to burn you. If you do not follow these steps exactly, some or all of these things can hurt you.
4. Open the hoods and locate the positive (+) and negative (−) terminal locations of the other vehicle. Your vehicle has a remote positive (+) jump starting terminal and a remote negative (−) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery. The remote positive (+) terminal is located behind a red plastic cover near the engine accessory drive bracket on the driver’s side of the engine compartment, below the alternator.
5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (−) will go to a heavy, unpainted metal engine part or to a remote negative (−) terminal if the vehicle has one.
Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by your warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal. To disconnect the jumper cables from both vehicles, do the following: 1. Disconnect the black negative (−) cable from the vehicle that had the dead battery. 2.
All-Wheel Drive Lubricant checks in this section also apply to these vehicles. However, there are two additional systems that need lubrication. Transfer Case When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See Scheduled Maintenance on page 6-4. How to Check Lubricant To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant.
Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See Scheduled Maintenance on page 6-4. How to Check Lubricant If you have the 1500 Series, the proper level is from 5/8 inch (15 mm) to 1 5/8 inch (40 mm) below the bottom of the filler plug hole. The proper level for the 2500 and 3500 Series is from 0 to 1/4 (6 mm) below the bottom of the filler plug hole. Add only enough fluid to reach the proper level.
If the level is below the bottom of the filler plug hole, you may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 3/8 inch (10 mm) below the filler plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Recommended Fluids and Lubricants on page 6-14.
Among those acts presumed to constitute tampering are the acts listed below. Insulation: • Removal of the noise shields or any underhood insulation. Engine: • Removal or rendering engine speed governor, if the vehicle has one, inoperative so as to allow engine speed to exceed manufacturer specifications. Fan and Drive: • Removal of fan clutch, if the vehicle has one, or Air Intake: • Removal of the air cleaner silencer. • Modification of the air cleaner.

Tire Sidewall Labeling Useful information about a tire is molded into the sidewall. The following illustrations are examples of a typical P-Metric and a LT-Metric tire sidewall. (B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines.
(G) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. For information on recommended tire pressure see Inflation - Tire Pressure on page 5-60 and Loading Your Vehicle on page 4-20. (B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines.
(G) Single Tire Maximum Load: Maximum load that can be carried and the maximum pressure needed to support that load when used as a single. For information on recommended tire pressure see Inflation - Tire Pressure on page 5-60 and Loading Your Vehicle on page 4-20. Tire Size The following examples show the different parts of a tire size. (A) Passenger (P-Metric) Tire: The United States version of a metric tire sizing system.
(E) Rim Diameter: Diameter of the wheel in inches. (F) Service Description: The service description indicates the load range and speed rating of a tire. The load index can range from 1 to 279. Speed ratings range from A to Z. Tire Terminology and Definitions Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in pounds per square inch (psi) or kilopascal (kPa). Accessory Weight: This means the combined weight of optional accessories.
GAWR RR: Gross Axle Weight Rating for the rear axle. See Loading Your Vehicle on page 4-20. Intended Outboard Sidewall: The side of an asymmetrical tire, that must always face outward when mounted on a vehicle. Kilopascal (kPa): The metric unit for air pressure. Light Truck (LT-Metric) Tire: A tire used on light duty trucks and some multipurpose passenger vehicles. Load Index: An assigned number ranging from 1 to 279 that corresponds to the load carrying capacity of a tire.
Rim: A metal support for a tire and upon which the tire beads are seated. Sidewall: The portion of a tire between the tread and the bead. Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road.
Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not.
How to Check Dual Tire Operation Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are underinflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem.
Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your vehicle’s tires and transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
Tire Pressure Monitor Operation The Tire Pressure Monitor System (TPMS), if your vehicle has this feature, is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the vehicle’s tires and transmits the tire pressure readings to a receiver located in the vehicle.
TPMS Malfunction Light and Message The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected.
TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. Any time you rotate your vehicle’s tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service.
If your vehicle does not have RKE, press the Driver Information Center (DIC) vehicle information button until the PRESS V TO RELEARN TIRE POSITIONS message displays. The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen. If your vehicle does not have RKE or DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the PRESS V TO RELEARN TIRE POSITIONS message displays.
Tire Inspection and Rotation We recommend that you regularly inspect your vehicle’s tires, including the spare tire, for signs of wear or damage. See When It Is Time for New Tires on page 5-70 for more information. Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 6-4. The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle.
{CAUTION: Dual Rear Wheels If your vehicle has dual rear wheels, always use one of the correct rotation patterns shown here when rotating the tires. When you install dual wheels, be sure that vent holes in the inner and outer wheels on each side are lined up. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Inflation - Tire Pressure on page 5-60 and Loading Your Vehicle on page 4-20.
When It Is Time for New Tires Various factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions, influence when you need new tires. One way to tell when it is time for new tires is to check the treadwear indicators, which appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators.
GM’s TPC Spec number is molded onto the tire’s sidewall near the tire size. If the tires have an all-season tread design, the TPC spec number will be followed by a MS, for mud and snow. See Tire Sidewall Labeling on page 5-54 for additional information. GM recommends replacing tires in sets of four (or six if your vehicle has dual rear wheels). This is because uniform tread depth on all tires will help keep your vehicle performing most like it did when the tires were new.
Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this could affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover. Additionally, if your vehicle has electronic systems such as anti-lock brakes, rollover airbags, traction control, and electronic stability control, the performance of these systems can be affected.
Uniform Tire Quality Grading Treadwear Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100.
Temperature – A, B, C Wheel Alignment and Tire Balance The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
{CAUTION: Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.
Tire Chains CAUTION: {CAUTION: If your vehicle has dual wheels or P245/75R16 or LT245/75R16 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash.
If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is much more likely to leak out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your vehicle’s hazard warning flashers. See Hazard Warning Flashers on page 3-6 for more information. CAUTION: (Continued) 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. {CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people.
Removing the Spare Tire and Tools If you have a cargo van or a passenger van, the equipment you will need is located in the passenger side rear corner of the vehicle. Remove the retaining wing bolt and lift it off of the mounting bracket. The following information tells you how to use the jack and change a tire. If you have a van with the 15-passenger seating arrangement, the equipment you will need is secured on the rear floor of the passenger side of the vehicle.
To access the equipment, remove the retaining wing bolt and lift it out of the mounting bracket. The tools you will be using include the jack (A), jack handle extension (B), jack handle (C), wheel wrench (D), and the ratchet (E). The spare tire is stored underneath the rear of your vehicle. You will use the wheel wrench (D) and the ratchet (E) to lower the spare tire from the vehicle.
To lower the spare tire from the vehicle: 1. Attach the wheel wrench and ratchet, with the DOWN side facing you. The wheel wrench has a socket end and a flat chisel end. Note that there is an UP side and a DOWN side on the ratchet. 2. Put the flat chisel end of the wheel wrench on an angle through the hole between the body and the bumper. Be sure the flat end connects into the hoist shaft. 3. Turn the ratchet counterclockwise to lower the spare tire to the ground.
Removing the Flat Tire and Installing the Spare Tire If your vehicle has plastic wheel nut caps, loosen them by turning the wheel wrench counterclockwise. The wheel nut caps are designed to remain with the center cap. Remove the center cap. If the wheel has a smooth center piece, place the chisel end of the wheel wrench in the slot on the wheel and gently pry it out. 1. Do a safety check before proceeding. See Changing a Flat Tire on page 5-78 for more information. 4.
3. Assemble the jack and tools: Rear Position Front Position Front Flat: Assemble the jack (A) together with the jack handle (B) and ratchet (C) as shown. Be sure that the ratchet has the UP mark facing you. Rear Flat: Assemble the jack (A) together with the jack handle (B), jack handle extension (C) and ratchet (D) as shown. Be sure that the ratchet has the UP mark facing you. To assemble the jack handle and jack handle extension, use the art and text following.
Front Position Connect the jack handle (B) and jack handle extension (C) together and press the retention clip (arrow) so it engages. 4. Position the jack under the vehicle as shown.
{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. 5.
6. Remove all the wheel nuts. 7. Take flat tire off of the mounting surface. 5-86 {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle.
8. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. 9. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand until the wheel is held against the hub. {CAUTION: Never use oil or grease on studs or nuts. Because the nuts might come loose. The vehicle’s wheel could fall off, causing a crash.
10. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. {CAUTION: Wheel nuts that are not tight can work loose. If all the nuts on a wheel come off, the wheel can come off the vehicle, causing a crash. All wheel nuts must be properly tightened. Follow the rules in this section to be sure they are. 5-88 {CAUTION: If wheel studs are damaged, they can break. If all the studs on a wheel broke, the wheel could come off and cause a crash.
{CAUTION: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new 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 on page 5-110 for wheel nut torque specification. Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage.
Secondary Latch System Your vehicle has an underbody-mounted tire hoist assembly equipped with a secondary latch system. It is designed to stop the spare tire from suddenly falling off the vehicle if the cable holding the spare tire is damaged. For the secondary latch to work, the tire must be stowed with the valve stem pointing down. See Storing a Flat or Spare Tire and Tools on page 5-93 for instructions on storing the spare tire correctly.
3. Connect the jack handle (A) and jack handle extension (B) together and press the retention clip (arrow) so it engages. 4. Attach the jack handle/jack handle extension to the jack. With the UP mark facing you, slide the ratchet onto the end of the jack handle extension.
8. Disconnect the jack handle from the jack and carefully remove the jack. Use one hand to push against the spare while firmly pulling the jack out from under the spare tire with the other hand. If the spare tire is hanging from the cable, slide the ratchet onto the wheel wrench and insert the wheel wrench into the hoist shaft hole above the bumper. Turn the wheel wrench counterclockwise to lower the spare the rest of the way. Be sure the DOWN mark on the ratchet is facing you. 9.
Storing a Flat or Spare Tire and Tools {CAUTION: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down. 2. Pull the retaining bar through the center of the wheel, making sure it is properly attached. 3.
Spare Tire Your vehicle, when new, had a fully-inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 5-60 and Loading Your Vehicle on page 4-20 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-82 and Storing a Flat or Spare Tire and Tools on page 5-93.
Appearance Care Interior Cleaning Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible.
Do not clean your vehicle using the following cleaners or techniques: • Never use a knife or any other sharp object to remove a soil from any interior surface. • Never use a stiff brush. It can cause damage to your vehicle’s interior surfaces. • Never apply heavy pressure or rub aggressively with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal. • Use only mild, neutral-pH soaps.
If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness first. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. Some commercial products may increase gloss on your instrument panel.
Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often. Notice: Certain cleaners contain chemicals that can damage the emblems or nameplates on your vehicle. Check the cleaning product label. If it states that it should not be used on plastic parts, do not use it on your vehicle or damage may occur and it would not be covered by the warranty. Do not wash the vehicle in direct sunlight. Use a car washing soap.
Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on your vehicle. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible.
Aluminum Wheels Notice: If you use strong soaps, chemicals, abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only approved cleaners on aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied.
Tires Underbody Maintenance To clean the tires, use a stiff brush with tire cleaner. Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires.
Vehicle Care/Appearance Materials Description Polishing Cloth Tar and Road Oil Remover Chrome Cleaner and Polish White Sidewall Tire Cleaner Vinyl Cleaner Glass Cleaner Chrome Wheel Cleaner Finish Enhancer 5-102 Usage Interior and exterior polishing cloth. Removes tar, road oil, and asphalt. Use on chrome or stainless steel. Removes soil and black marks from whitewalls and raised white lettering. Cleans vinyl. Removes dirt, grime, smoke and fingerprints. Removes dirt and grime from chrome wheels.
Vehicle Identification Service Parts Identification Label Vehicle Identification Number (VIN) This label is on the front passenger door frame. It is very helpful if you ever need to order parts. The label has the following information: • • • • Vehicle Identification Number (VIN) Model designation Paint information Production options and special equipment Do not remove this label from the vehicle. This is the legal identifier for your vehicle.
Headlamp Wiring Fuses and Circuit Breakers The headlamp wiring is protected by fuses in the engine compartment fuse block. An electrical overload will cause the lamps to flicker on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems.
