How to Use this Manual Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you’ll find that pictures and words work together to explain things quickly. CAUTION: These mean there is something that could hurt you or other people. In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard.
Vehicle Damage Warnings Vehicle Symbols Also, in this book you will find these notices: Your vehicle may be equipped with components and labels that use symbols instead of text. Symbols, used on your vehicle, are shown along with the text describing the operation or information relating to a specific component, control, message, gage or indicator. NOTICE: These mean there is something that could damage your vehicle.

Section 1 Seats and Restraint Systems Here you’ll find information about the seats in your vehicle and how to use your safety belts properly. You can also learn about some things you should not do with air bags and safety belts.
Seats and Seat Controls This section tells you about the seats -- how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints. Power Seats Horizontal Control: You can adjust your vehicle’s front seats with the horizontal control located on the outboard edge of each front seat. Raise or lower the front of the seat by raising or lowering the forward edge of the control.
Power Lumbar Control Use the lumbar control, located on the outboard side of the seat, to increase or decrease lumbar support in an area of the lower seatback. To increase support, press and hold the front of the control. To decrease support, press and hold the rear of the control. Let go of the control when the lower seatback reaches the desired level of support. You can also reshape the side wing area of the lower seatback for more lateral support.
Heated Front Seats Reclining Front Seatbacks The button for the driver’s side heated seat is located on the driver’s side door panel. The button for the passenger’s side heated seat is located on the passenger’s side door panel. Your vehicles front seatbacks have a recline feature. The ignition must be in RUN for this feature to operate. To activate the heated seats, press the button once for the HI heat setting. Press the button again for the LO heat setting.
CAUTION: But don’t have a seatback reclined if your vehicle is moving. Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this. The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones.
Head Restraints Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash. The head restraints tilt forward and rearward also. To tilt the head restraint forward, grasp the top of the restraint and move it forward until you hear a click. It will then be locked into that position until you need to move it again.
The rear seat can be folded open for more seating space. To use the seat do the following: Rear Seat Folding the Rear Seat The rear seat can be folded up to provide more cargo space. To fold the seat do the following: 1. Pull forward on the release strap located under the rear seat cushion. 1. Push rearward on the seat cushion while pulling up on the release strap under the seat cushion. 2. Pull the seat cushion downward until it latches. 3.
Safety Belts: They’re 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. And it explains the air bag system. CAUTION: Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed.
Your vehicle has a light that comes on as a reminder to buckle up. See “Safety Belt Reminder Light” in the Index. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one. A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t survive.
Put someone on it. 1-10 Get it up to speed. Then stop the vehicle. The rider doesn’t stop.
The person keeps going until stopped by something. or the instrument panel ... In a real vehicle, it could be the windshield ...
Here Are Questions Many People Ask About Safety Belts -- and the Answers Q: Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? 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’s why safety belts make such good sense. 1-12 A: You could be -- whether you’re wearing a safety belt or not.
Q: If I’m a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you’re in an accident -- even one that isn’t your fault -- you and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h). Safety belts are for everyone.
4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly.
The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.
Q: What’s wrong with this? CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. A: The shoulder belt is too loose. It won’t give nearly as much protection this way.
Q: What’s wrong with this? CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place.
Q: What’s wrong with this? CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. A: The belt is over an armrest.
Q: What’s wrong with this? CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What’s wrong with this? CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it. A: The belt is twisted across the body.
Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.
The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly. Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.
CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with air bags. The driver should sit as far back as possible while still maintaining control of the vehicle.
How the Air Bag System Works The right front passenger’s air bag is in the instrument panel on the passenger’s side. Where are the air bags? The driver’s air bag is in the middle of the steering wheel.
CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering.
How does an air bag restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. Air bags supplement the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
D Your vehicle is equipped with a crash sensing and diagnostic module, which records information about the air bag system. The module records information about the readiness of the system, when the system commands air bag inflation and driver’s safety belt usage at deployment. The module also records speed, engine rpm, brake and throttle data. Air Bag Off Switch Your vehicle has a switch on the instrument panel that you can use to turn off the right front passenger’s air bag.
This switch should only be turned to AIR BAG OFF if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Medical Condition. A passenger has a medical condition which, according to his or her physician: Infant.
CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off.
Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see “Service and Owner Publications” in the Index.
Adding Equipment to Your Air Bag-Equipped Vehicle Q: If I add a push bumper or a bicycle rack to the front of my vehicle, will it keep the air bags from working properly? A: As long as the push bumper or bicycle rack is attached to your vehicle so that the vehicle’s basic structure isn’t changed, it’s not likely to keep the air bags from working properly in a crash. Q: Is there anything I might add to the front of the vehicle that could keep the air bags from working properly? A: Yes.
Center Passenger Position Lap Belt When you sit in a center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt.
To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap-shoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Rear Seat Passengers Lap-Shoulder Belt It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.
1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again.
CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head. There is one guide for each outside passenger in the rear seat.
2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 1-38 3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt.
Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint.
CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap-shoulder belts offer outstanding protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide.
Q: What are the different types of add-on child restraints? 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.
CAUTION: Restraint Systems for Children 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’s unprotected by any bony structure. This alone could cause serious or fatal injuries.
A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. 1-44 A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields.
Q: A: How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint.
When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards. Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.
CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. anchored. Others require the top strap always to be anchored. Be sure to read and follow the instructions for your child restraint.
In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Right Front Passenger Position Top Strap Anchor Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed.
Rear Seat Top Strap Anchors You’ll find the top strap anchors for the rear seating positions near the top of the seatback. In addition to the top strap anchors, each seating position has a fabric loop at the top of the seatback that you’ll use to route a top strap through. When using a child restraint with a top strap in either rear outboard position, raise the head restraint and route the top strap through the fabric loop on the seatback.
Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle may have the LATCH system. If it does, you’ll find anchors (A) in the front passenger seat, where the seatback meets the seat cushion, and anchors (A) in the center rear seat, where the seatback meets the seat cushion. For front passenger seat position, there is a top tether anchor (C) behind and to the bottom of the seat to secure the top strap.
In order to use the system, you need either a forward-facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear-facing child restraint that has attaching points (B), as shown here.
CAUTION: If a LATCH-type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect a child sitting there. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint. See “Child Restraints” in the Index for information on how to secure a child restraint in your vehicle using the vehicle’s safety belts.
Securing a Child Restraint Designed for the LATCH System Securing a Child Restraint in a Rear Outside Seat Position 1. Find the anchors for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion. There is limited space in the rear seating area. If you want to secure a child restraint in a rear outside seating position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly. 2.
You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1. Put the 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. 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6. Push and pull the child restraint in different directions to be sure it is secure.
Securing a Child Restraint in the Center Rear Seat Position If your child restraint is equipped with the LATCH system, see “Lower Anchorages and Top Tethers for Children (LATCH)” in the Index. You can secure a child restraint in the center rear seat position. There is limited space in the rear seating area.
3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To tighten the belt, pull its free end while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6.
Securing a Child Restraint in the Right Front Seat Position If your child restraint is equipped with the LATCH system, see “Lower Anchorages and Top Tethers for Children (LATCH)” in the Index. Your vehicle has a right front passenger air bag. There’s a switch on the instrument panel that you can use to turn off the right front passenger’s air bag when you want to secure a rear-facing child restraint at the right front passenger’s position.
CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. If a forward-facing child restraint is suitable for your child, always move the passenger seat as far back as it will go.
You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1. Your vehicle has a right front passenger’s air bag. If you are using a rear-facing child restraint in this seat, make sure the air bag is turned off. See “Air Bag Off Switch” in the Index.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 7. Push and pull the child restraint in different directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. If you were using a rear-facing child restraint, turn on the right front passenger’s air bag when you remove the rear-facing child restraint from the vehicle unless the person who will be sitting there is a member of a passenger air bag risk group. See “Air Bag Off Switch” in the Index.
Older Children Q: A: What is the proper way to wear safety belts? If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.
CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs.
Safety Belt Extender Checking Your Restraint Systems If the vehicle’s safety belt will fasten around you, you should use it. Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.
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.
Section 2 Features and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly -- and what to do if you have a problem.
Windows CAUTION: Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather.
Express-Down Window Power Windows A power window control is located on the inside of each front door. The driver’s window also has an express down feature that allows the window to be lowered without holding the switch. Press and hold the rear of the switch marked AUTO briefly to activate the express down mode. The express down mode can be canceled at any time by pressing the opposite side of the switch. To open the window partway, lightly tap the switch until the window is at the desired position.
Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
Your vehicle has one double-sided key for the ignition and all door locks. NOTICE: Your vehicle has a number of new features that can help prevent theft. But you can have a lot of trouble getting into your vehicle if you ever lock your key inside. You may even have to damage your vehicle to get in. So be sure you have an extra key. Your vehicle also has a key that locks and unlocks only the center floor console. If you ever do get locked out of your vehicle, call the GM Roadside Assistance Center.
Door Locks CAUTION: Unlocked doors can be dangerous. D Passengers -- especially children -- can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive. D Young children who get into unlocked vehicles may be unable to get out.
Power Door Locks Keyless Entry System Press the raised side of the switch, marked L on either front door, to lock all the doors at once. Press the recessed side of the switch marked U to unlock all the doors at once. The power door locks will operate at any time without the ignition being on. The power door locks can be programmed to automatically lock and unlock depending on the settings you have chosen in the secondary information center.
At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: D Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather. D Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again.
Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched.
To open a rear access door from the inside, the front door must be opened first. Then, use the handle located on the inside of the rear access door to open it. Rear Doors Your vehicle is equipped with rear access doors that allow easier access to the rear area of the extended cab. To open a rear access door from the outside, first open the front door. Then, use the handle located on the front edge of the rear access door to open it.
Tailgate Removal The tailgate on your vehicle can be removed to allow for different loading situations. Although the tailgate can be removed without assistance, you may want someone to assist you with the removal to avoid possible damage to the vehicle. 2. With the tailgate at a slightly upward angle, pull back on the tailgate at the right edge and then move the tailgate to the right to release the left edge. To remove the tailgate, do the following: 1.
Theft Parking at Night Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. Park in a lighted spot, close all windows and lock your vehicle. Remember to keep your valuables out of sight. Put them in a storage area, or take them with you.
Content Theft-Deterrent Your vehicle is equipped with a content theft-deterrent alarm system. You can disable the system or personalize it to suit your needs. See “Secondary Information Center” in the Index for more information. With this system, the SECURITY message on the cluster will flash as you open the door (if your ignition is off). This message reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2.
Here’s how to avoid setting off the alarm by accident: D If you don’t want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. D Always unlock a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm if the system has been armed. If you set off the alarm by accident, unlock any door with the key.
PasslockR Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. If the engine stalls and the SECURITY message flashes, wait until the message stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.
Ignition Positions With your key in the ignition switch you can turn it to five different positions. ACCESSORY (A): This position lets you use things like the radio, power windows and the windshield wipers when the engine is off. Push in the key and turn it toward you. NOTICE: If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch.
Starting Your Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position -- that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only. NOTICE: Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped. 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key.
When starting your engine in very cold weather (below 0_F or -18_C), do this: Engine Coolant Heater (If Equipped) In very cold weather, 0_F (-18_C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm-up. 1. With your foot off the accelerator pedal, turn the ignition key to START and hold it there up to 15 seconds. When the engine starts, let go of the key. 2.
3. Plug it into a normal, grounded 110-volt AC outlet. Automatic Transmission Operation CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord won’t reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 4.
There are several different positions for your shift lever. PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly.
CAUTION: Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Don’t shift out of PARK (P) or NEUTRAL (N) while your engine is racing. NOTICE: Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty.
FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough. Tow/Haul Mode Switch NOTICE: If your rear wheels can’t turn, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object.
Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. If the ignition is on, the brake system warning light will flash. A chime will sound when the parking brake is applied and the vehicle is moved at least 3 mph (5 km/h) for at least three seconds. If the ignition is on when the parking brake is released, the brake system warning light will go off.
Shifting Into PARK (P) CAUTION: 1. Hold the brake pedal down with your right foot and set the parking brake. 2. Move the shift lever into PARK (P) like this: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, use the steps that follow.
Leaving Your Vehicle With the Engine Running CAUTION: D Move the lever up as far as it will go. 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. Don’t leave your vehicle with the engine running unless you have to. 3. Turn the ignition key to LOCK. 4.
Torque Lock Shifting Out of PARK (P) If you are parking on a hill and you don’t shift your transmission into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of PARK (P). This is called “torque lock.” To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver’s seat. To find out how, see “Shifting Into PARK (P)” in the Index.
Parking Over Things That Burn Engine Exhaust CAUTION: CAUTION: Things that can burn could touch hot exhaust parts under your vehicle and ignite. Don’t park over papers, leaves, dry grass or other things that can burn. Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can’t see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: D Your exhaust system sounds strange or different. D Your vehicle gets rusty underneath.
Running Your Engine While You’re Parked It’s 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.” Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the fan is at the highest setting. One place this can happen is a garage.
Locking Rear Axle If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. QUADRASTEERt (4WS) The QUADRASTEER System has a control and diagnostic module that monitors and records current system status and operational information.
The switch is located on the instrument panel. 2WS: In this mode the vehicle will operate like any other vehicle with two wheel steering. If you want to use 2WS and your vehicle is not in this mode, press the 4 Wheel Steer button until the 2WS indicator, located to the right of the 4 Wheel Steer button, lights up. If the 2WS indicator is flashing you will have to center the steering wheel by turning it to the left or right. 4WS: In this mode all four wheels will help steer the vehicle.
4WS TOW: The 4WS TOW mode provides enhanced stability allowing the trailer to follow the path of the tow vehicle more closely, especially during lane changes. In this mode the system operates much like the 4WS mode, but is enhanced for trailer towing. It is recommended for all types and weights of trailers. Higher Speed Mode (40 mph/64 kph and above) At higher speeds the steering will operate in the higher speed mode. This means the front and rear wheels will turn in the same direction.
Car Washes for QUADRASTEER Equipped Vehicles NOTICE: Because your vehicle has a wider rear track some car washes may be too narrow for your vehicle. Conveyor systems on some automatic car washes may damage your vehicle. Only use conveyor system car washes with 13-inch (33 cm) wide conveyor rails and/or stationary washes with at least 82 inches (208 cm) between the rails. Before using the car wash check with the manager.
Horn Turn Signal/Multifunction Lever To sound the horn, press the center pad on the steering wheel. Tilt Wheel A tilt wheel allows you to adjust the steering wheel before you drive. You can raise it to the highest level to give your legs more room when you exit and enter your vehicle. The tilt steering wheel lever is located on the lower left side of the steering column. To tilt the wheel, hold the steering wheel and pull the lever.
Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically. An arrow on the instrument panel cluster will flash in the direction of the turn or lane change. If a bulb is burned out, replace it to help avoid an accident.
Flash-to-Pass Feature This feature allows you to use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are off. To use it, pull the turn signal lever toward you, but not so far that you hear it click. If your headlamps are off or on low beam, your high-beam headlamps will turn on. They’ll stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel will come on.
Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). CAUTION: D Cruise control can be dangerous where D you can’t drive safely at a steady speed. So, don’t use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads.
Increasing Speed While Using Cruise Control United States Canada The CRUISE light on the instrument panel cluster will illuminate when the cruise control is engaged. Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you don’t need to reset it. Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch from ON to R/A (Resume/Accelerate) briefly.
Using Cruise Control on Hills Exterior Lamps How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don’t use cruise control on steep hills.
The exterior lamp control has three positions: Automatic Headlamp System (OFF): Turning the control to this position turns off all lamps, except the Daytime Running Lamps (DRL). It also puts the system into automatic headlamp mode. When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim.
There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay. To idle your vehicle with the automatic headlamp system off, set the parking brake while the ignition is off.
When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps or the last chosen headlamp setting that was used. When you turn the exterior lamp control to off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside. To idle your vehicle with the DRL off, set the parking brake, before starting the vehicle. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off.
Fog Lamps You can use your vehicle’s fog lamps for better vision in foggy or misty conditions. The fog lamp button is located on the left side of your instrument panel. Press the button to turn the fog lamps on while the headlamps are on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use the fog lamps in the dark without turning on the headlamps.
Interior Lamps Illuminated Entry Instrument Panel Brightness Control Your vehicle is equipped with an illuminated entry feature. This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the exterior lamp control. Turn the thumbwheel up to adjust the instrument panel lights and return the radio display to full brightness when the headlamps or parking lamps are on.
Dome Lamps The dome lamps will come on when you open a door and the dome override button is in the out position. You can also turn the dome lamps on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the dome lamps will remain on whether the doors are opened or closed. You can use the DOME OVERRIDE button, located below the exterior lamps control, to set the dome lamps to come on automatically when the doors are opened, or to remain off.
Mirrors Electrochromic Inside Rearview Mirror with Compass, Temperature Display and OnStar Controls When on, an electrochromic mirror automatically dims to the proper level to minimize glare from lights behind you after dark. Temperature and Compass Display Press the on/off button, located to the far left, briefly to turn the comp/temp display on or off. If the display reads CAL, you will need to calibrate the compass. For more information on calibration, see below.
Electrochromic Mirror Operation To adjust for compass variance do the following: The electrochromic (self-dimming) mirror function is turned on automatically each time the engine is started. To operate the electrochromic mirror do the following: 1. Find your current location and variance zone number on the following zone map. 1. Make sure the green indicator light, located to the left of the on/off button, is lit.
3. Keep pressing the on/off button until the desired zone number appears in the display. Release the button. After about four seconds of inactivity, the new zone number will be locked in and the comp/temp display will return. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push the on/off button for approximately 12 seconds or until CAL is displayed. 4. Calibrate the compass as described below.
Power Outside Rearview Mirrors Convex Outside Mirror Your passenger’s side mirror is convex. A convex mirror’s surface is curved so you can see more from the driver’s seat. CAUTION: A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on your right. Check your inside mirror or glance over your shoulder before changing lanes.

For more information on the air bag system, see “Air Bag” in the Index.
Air Bag Off Light When you turn the right front passenger’s air bag off, this light will come on and stay on to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See “Air Bag Off Switch” in the Index for more on this, including important safety information.
Voltmeter CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off.
When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at idle speed.
If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the floor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See “Towing Your Vehicle” in the Index. Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal.
Engine Coolant Temperature Gage 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. If the gage reaches the 260_F (125_C) mark, it indicates that the cooling system is working beyond its capacity.
At approximately 265_F (130_C), the message center will display a TRANS FLUID HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260_F (127_C).
Malfunction Indicator Lamp (Service Engine Soon Light in the United States or Check Engine Light in Canada) United States NOTICE: If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty.
This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light doesn’t come on, have it repaired. This light will also come on during a malfunction in one of two ways: D Light Flashing -- A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service may be required.
Did you just drive through a deep puddle of water? Emissions Inspection and Maintenance Programs If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration.
Oil Pressure Gage CAUTION: Don’t keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).
Cruise Light United States Fuel Gage Canada The CRUISE light comes on whenever you set your cruise control. See “Cruise Control” in the Index. Tow/Haul Light This light is displayed when the tow/haul mode has been activated. For more information see, “Tow/Haul Mode” in the Index. 2-76 United States Canada When the ignition is on, the fuel gage tells you about how much fuel you have left in your tank.
Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. D At the gas station, the fuel pump shuts off before the gage reads full. D It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank. D The gage goes back to empty when you turn off the ignition.
Trans Fluid Hot NOTICE: The automatic transmission temperature warning display is contained in the message center. If you keep driving your vehicle with the transmission TRANS FLUID HOT message displayed, you can damage the transmission. This could lead to costly repairs that may not be covered under your warranty. If the transmission fluid temperature becomes high, the message center will display this message.
Low Coolant Engine Overheated This message is displayed when the cooling system is low on coolant. The engine may overheat. See “Engine Coolant” in the Index and have your vehicle serviced as soon as you can. Check Coolant Temp This message is displayed when the cooling system temperature gets hot. Check the coolant temperature gage and the coolant level. See “Engine Coolant” and “Engine Coolant Temperature Gage” in the Index. This message is displayed when the cooling system temperature gets too hot.
Check Eng Oil Pressure Change Engine Oil This message is displayed when the engine oil pressure is low. See “Oil Pressure Gage” in the Index for more information. Check Eng Oil Level This message is displayed when the engine oil level is low. Once oil is added, it may need time to drain and settle in the engine before this message will turn off. It is best to let the engine cool down (if it is hot) or warm up (if it is cold) and cycle the ignition to be sure this message turns off.
Low Washer Fluid Low Fuel This message is displayed when the vehicle is low on windshield washer fluid. The message is only displayed for 15 seconds at the start of each ignition cycle. For more information see, “Windshield Washer Fluid” in the Index. This message is displayed when your vehicle is low on fuel. Refer to the fuel gage for a better indication of the amount of fuel remaining in the fuel tank.

Section 3 Comfort Controls and Audio Systems In this section, you’ll find out how to operate the comfort control and audio systems offered with your vehicle. Be sure to read about the particular systems supplied with your vehicle.
Comfort Controls Heater and Air Conditioning Comfort Controls Temperature Knob The middle knob on the control panel lets you select the temperature of the air flowing into the passenger area. Turn the knob clockwise toward the red area for warmer air. Turn the knob counterclockwise toward the blue area for cooler air. Mode Knob The right knob on the control panel allows you to choose the direction of air delivery.
(Floor): This mode directs most of the air through the floor outlets and center floor console outlets, as well as some air through the windshield defroster outlets and side window defroster outlets. If air from the center floor console outlets is not desired, turn the vents off at the console. (Defog): Airflow is delivered through the floor outlets, center floor console outlets, the windshield defroster outlets and the side window defroster outlets.
Recirculation will not be available in floor, blend, or defrost modes. This helps reduce window fogging. If the recirculation button is pressed in these modes, the LED indicator for recirculation will flash three times indicating that outside air is activated and recirculation is not available.
Heating Defogging and Defrosting The heater works best if you keep your windows closed while using it. On cold days, use the floor or bi-level modes with the temperature knob in the red area. On cool, humid days, use blend mode to keep the windshield and side windows clear. Use defrost mode to remove fog or ice from the windshield in extremely humid or cold conditions. Use defrost mode with the temperature knob toward the red area and the fan knob turned all the way clockwise.
Rear Window Defogger The lines running across the rear window are the rear window defogger. The lines warm the glass. To turn on the rear window defogger, press this button next to the fan knob. The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button. The rear window defogger button will also activate the heated outside mirrors.
Ventilation System For mild outside temperatures when little heating or cooling is needed, use vent and the outside air setting to direct outside air through your vehicle. Air will flow in through the instrument panel outlets. Your vehicle has air outlets in the center and on the sides of your instrument panel. Your vehicle’s ventilation system supplies outside air to the inside of your vehicle when it is moving.
Ventilation Tips D Keep the hood and front air inlet free of ice, snow or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. D When you enter a vehicle in cold weather, turn the fan knob all the way toward the red area for a few moments before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your windows.
AM-FM Stereo with Cassette Tape Player and Automatic Tone Control SCV (Speed-Compensated Volume): With SCV, your audio system adjusts automatically to make up for road and wind noise as you drive. Set the volume at the desired level. Turn the control ring behind the upper knob clockwise to adjust the SCV. Each notch on the control ring allows for more volume compensation at faster vehicle speeds. Then, as you drive, SCV automatically increases the volume, as necessary, to overcome noise at any speed.
SEEK : Press the right or left arrow to seek to the next or previous station and stay there. The radio will seek to stations with a strong signal only. The sound will mute while seeking. To scan station, press and hold SEEK for two seconds until SCAN appears on the display.

Understanding Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it. FM Stereo FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km).
Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes or a damaged mechanism. Cassette tapes should be stored in their cases away from contaminants, direct sunlight and extreme heat. If they aren’t, they may not operate properly or may cause failure of the tape player.
After you clean the player, press and hold the EJECT button for five seconds to reset the CLN indicator. The radio will display --- to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before you have your tape player serviced. Care of Your Compact Discs Handle discs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust.
Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving.
Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It’s the best defensive driving maneuver, in both city and rural driving.
Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: D D D D Judgment Muscular Coordination Vision Attentiveness. Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving.
Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks. The law in an increasing number of U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.
The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision. There’s something else about drinking and driving that many people don’t know.
Control of a Vehicle Braking You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That’s perception time. Then you have to bring up your foot and do it. That’s reaction time. Average reaction time is about 3/4 of a second.
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. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life.
The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Let’s say the road is wet and you’re driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS: A computer senses that wheels are slowing down.
Remember: Anti-lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Steering Tips Using Anti-Lock Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves.
Suppose you’re steering through a sharp curve. Then you suddenly accelerate. Both control systems -- steering and acceleration -- have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed.
Off-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object.
Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds.
D Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. (Remember that if your right outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is.) D Try not to pass more than one vehicle at a time on two-lane roads.
Of course, traction is reduced when water, snow, ice, gravel or other material is on the road. For safety, you’ll want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited. While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration or braking (including engine braking by shifting to a lower gear).
Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields (if so equipped) are properly attached. Is there enough fuel? Is the spare tire fully inflated? Are the fluid levels up where they should be? What are the local laws that apply to off-roading where you’ll be driving? If you don’t know, you should check with law enforcement people in the area.
Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GM recognizes these concerns and urges every off-roader to follow these basic rules for protecting the environment: D Always use established trails, roads and areas that have been specially set aside for public off-road recreational driving; obey all posted regulations.
Controlling your vehicle is the key to successful off-road driving. One of the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds: D you approach things faster and you have less time to scan the terrain for obstacles. D you have less time to react. D you have more vehicle bounce when you drive over obstacles. D you’ll need more distance for braking, especially since you’re on an unpaved surface.
When you drive over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs or other surface features can jerk the wheel out of your hands if you’re not prepared. When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground. If this happens, even with one or two wheels, you can’t control the vehicle as well or at all. Because you will be on an unpaved surface, it’s especially important to avoid sudden acceleration, sudden turns or sudden braking.
Approaching a Hill When you approach a hill, you need to decide if it’s one of those hills that’s just too steep to climb, descend or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top. On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs.
Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. D Use a low gear and get a firm grip on the steering wheel. D Get a smooth start up the hill and try to maintain your speed. Don’t use more power than you need, because you don’t want your wheels to start spinning or sliding. D Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route.
Q: A: What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you should do: D Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. D If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R).
Q: Suppose, after stalling, I try to back down the hill and decide I just can’t do it. What should I do? A: Set the parking brake, put your transmission in PARK (P) and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill.
Q: Are there some things I should not do when driving down a hill? A: Q: A: Yes! These are important because if you ignore them you could lose control and have a serious accident. D Stop your vehicle by applying the regular brakes. D When driving downhill, avoid turns that take you D Shift to PARK (P) and, while still braking, restart across the incline of the hill. A hill that’s not too steep to drive down may be too steep to drive across. You could roll over if you don’t drive straight down.
Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: D A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base (the distance from the front wheels to the rear wheels) reduces the likelihood the vehicle will tumble end over end.
Q: What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and “walk the course” so you know what the surface is like before you drive it.
Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction. You can’t accelerate as quickly, turning is more difficult, and you’ll need longer braking distances. It’s best to use a low gear when you’re in mud -- the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you don’t get stuck. When you drive on sand, you’ll sense a change in wheel traction. But it will depend upon how loosely packed the sand is.
Driving in Water Light rain causes no special off-road driving problems. But heavy rain can mean flash flooding, and flood waters demand extreme caution. Find out how deep the water is before you drive through it. If it’s deep enough to cover your wheel hubs, axles or exhaust pipe, don’t try it -- you probably won’t get through. Also, water that deep can damage your axle and other vehicle parts. If the water isn’t too deep, then drive through it slowly.
After Off-Road Driving Driving at Night Remove any brush or debris that has collected on the underbody, chassis or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage.
Here are some tips on night driving. D Drive defensively. D Don’t drink and drive. D Adjust your inside rearview mirror to reduce the glare from headlamps behind you. D Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles. D Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead. D In remote areas, watch for animals. D If you’re tired, pull off the road in a safe place and rest.
Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire-to-road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction. It’s always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. The heavier the rain, the harder it is to see.
CAUTION: Wet brakes can cause accidents. They won’t work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally. Hydroplaning Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles.
Driving Through Deep Standing Water Driving Through Flowing Water NOTICE: CAUTION: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you can’t avoid deep puddles or standing water, drive through them very slowly. Flowing or rushing water creates strong forces.
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: D Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. D Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy.
Freeway Driving At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the flow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic flow.
The exit speed is usually posted. Here are some things you can check before a trip: Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are.
Highway Hypnosis Hill and Mountain Roads Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy.
If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. See “Operating Your Vehicle Off Paved Roads” in the Index for information about driving off-road. CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they wouldn’t work well. You would then have poor braking or even none going down a hill.
Winter Driving Here are some tips for winter driving: D Have your vehicle in good shape for winter. D You may 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. Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti-lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-Lock” in the Index.
If You’re Caught in a Blizzard D Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow. D Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats -- anything you can wrap around yourself or tuck under your clothing to keep warm. If you are stopped by heavy snow, you could be in a serious situation.
CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t 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 your exhaust pipe. And check around again from time to time to be sure snow doesn’t collect there. Open a window just a little on the side of the vehicle that’s away from the wind.
Recreational Vehicle Towing Loading Your Vehicle Recreational vehicle towing means towing your vehicle behind another vehicle -- such as behind a motorhome. The two most common types of recreational vehicle towing are known as “dinghy towing” (towing your vehicle with all four wheels on the ground) and “dolly towing” (towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”). Your vehicle was not designed to be towed with any of its wheels on the ground.
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. And, if you do have a heavy load, you should spread it out.
Payload CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. D Put things in the cargo area of your vehicle. Try to spread the weight evenly. D Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. D Don’t leave an unsecured child restraint in your vehicle. D When you carry something inside the vehicle, secure it whenever you can. D Don’t leave a seat folded down unless you need to.
2-Tiered Loading Add-On Equipment By positioning four 2″ x 6″ wooden planks across the width of the pickup box, you can create an upper load platform. The planks must be inserted in the pickup box depressions. The length of the planks must allow for at least a 3/4 inch (2 cm) bearing surface on each end of the plank. When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment.
Truck-Camper Loading Information This label is inside your glove box. It will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out your load. Also, it will help you match the right slide-in camper to your vehicle. Refer to the Truck-Camper Loading Information label in glove box for dimensions A and B as shown in the following illustration.
Here is an example of proper truck and camper match: If your slide-in camper and its load weighs less than the CWR, the center of gravity zone for your vehicle may be larger. Your dealer can help you make a good vehicle-camper match. He’ll also help you determine your CWR. After you’ve loaded your vehicle and camper, drive to a weigh station and weigh the front and rear wheels separately. This will tell you the loads on your axles.
Trailer Recommendations Pickup Conversion to Chassis Cab You must subtract your hitch loads from the CWR for your vehicle. Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the equalizer bars in place. General Motors is aware that some vehicle owners may consider having the pickup box removed and a commercial or recreational body installed.
Towing a Trailer CAUTION: If you don’t 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. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle.
If You Do Decide To Pull A Trailer If you do, here are some important points: D 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. D Consider using a sway control if your trailer will weigh 5,000 lbs. (2 270 kg) or less.
Tow/Haul Mode Tow/haul is a feature that assists when pulling a heavy trailer or a large or heavy load. The purpose of the tow/haul mode is to: D Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load. D Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded.
Weight of the Trailer How heavy can a trailer safely be? It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions.
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. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too.
Hitches Trailer Brakes It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly.
Driving with a Trailer Following Distance Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself.
Making Turns NOTICE: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Parking on Hills CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: D start your engine, D shift into a gear, and D release the parking brake. 2. Let up on the brake pedal. 3.
Trailer Wiring Harness The eight-wire harness contains the following trailer circuits: Heavy-Duty Trailer Wiring Package D D D D D D Yellow: Left Stop/Turn Signal Dark Green: Right Stop/Turn Signal Brown: Taillamps White: Ground Light Green: Back-up Lamps Light Blue: Center High-Mounted Stoplamp (CHMSL) D Red: Battery Feed D Dark Blue: Trailer Brake Your pickup is equipped with the eight-wire trailer towing harness.
Instrument Panel Jumper Wiring Harness Four Wire Trailer Harness Adapter If you need to tow a light-duty trailer with a standard four-way round pin connector, an adapter connector is included with your vehicle. Connect the adapter with the tab (arrow) pointing towards the top. The cap on the wiring harness will lock onto the tab (arrow) and help hold the adapter in place. This harness is included with the heavy-duty and camper/fifth-wheel trailer wiring packages.
Section 5 Problems on the Road Here you’ll find what to do about some problems that can occur on the road.
Hazard Warning Flashers The hazard warning flasher button is located at the top of the steering column. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. Press the button to make the front and rear turn signal lamps flash on and off. Press the button again to turn the flashers off. Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.
Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to following the steps below to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure.
CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don’t need to add water to the ACDelcoR battery (or batteries) installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present.
6. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one. 5-6 7. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.
8. Now connect the black negative (-) cable to the good battery’s negative (-) terminal. Use a remote negative (-) terminal if the vehicle has one.

Disconnect the black negative (-) cable from the vehicle with the good battery. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle. 5. Return the positive (+) remote terminal cover to its original position. Jumper Cable Removal A.
Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See “Roadside Assistance” in the Index. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see “Recreational Vehicle Towing” in the Index. Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. See “Engine Coolant Temperature Gage” in the Index.
If Steam Is Coming From Your Engine CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned.
NOTICE: If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If your air conditioner is on, turn it off. If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index for information on driving to a safe place in an emergency.
Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see: If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. The vehicle should be parked on a level surface. The coolant level should be at or above the FULL COLD mark. If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap C.
CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t 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 your engine without coolant isn’t covered by your warranty.
How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level isn’t at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See “Engine Coolant” in the Index for more information.
CAUTION: (Continued) your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant. NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant. 1. Park the vehicle on a level surface.
2. Then keep turning the pressure cap slowly, and remove it. 5-16 3. Then fill the coolant surge tank with the proper mixture, to the FULL COLD mark.
5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark.
Engine Fan Noise If a Tire Goes Flat 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.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. CAUTION: Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine. 4.
Removing the Spare Tire and Tools The equipment you’ll need is under the passenger’s side second row seat. The spare tire is located underneath the vehicle. 1. Pull up the second row seat with the loop at the base of the seat cushion to access the tools. 2. The wheel blocks and the wheel block retainer can be removed by turning the wing nut counterclockwise. 3. To release the bottle jack from its holder, turn the knob on the bottle jack counterclockwise to lower the jack head slightly. 4.
Follow these instructions to lower the spare tire: 1. Your vehicle is equipped with a hoist lock. Open the spare tire lock cover on the bumper and use the ignition key to remove the lock. 2. Assemble the wheel wrench and the two jack handle extensions as shown. Insert the hoist end (open end) of the extension through the hole in the rear bumper. Be sure the hoist end of the extension connects into the hoist shaft. 3. Turn the wheel wrench counterclockwise to lower the spare tire to the ground.
The tools you’ll be using include the bottle jack (A), the wheel blocks (B), the jack handle (C), the jack handle extensions (D), and the wheel wrench (E). If the flat tire is on a rear tire of the vehicle, you’ll need to use both jack handle extensions. 5-22 Attach the wheel wrench to the jack handle extensions (as needed). Attach the jack handle to the jack.
To remove the center cap place the chisel end of the wheel wrench in the slot on the wheel and gently pry out. Turn the wheel wrench clockwise to raise the jack lift head a little.
Removing the Flat Tire and Installing the Spare Tire 1. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts. Don’t remove them yet. 2. Position the jack under the vehicle. If the flat tire is on the front of the vehicle, position the jack on the frame behind the flat tire. If the flat tire is on the rear, position the jack under the rear axle between the spring anchor and the shock absorber bracket.
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.
4. Remove all the wheel nuts and take off the flat tire. Rear Position 3. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit under the wheel well. 5-26 5. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.
CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. 6.
Front Position Rear Position 7. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
8. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise. CAUTION: NOTICE: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. When you reinstall the full-size wheel and tire, you must also reinstall the center cap. Place the cap on the wheel and tap it into place until it seats flush with the wheel.
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. Return the bottle jack, wheel blocks, wheel wrench and jack extensions to their location under the passenger’s side second row seat. Secure the items in the vehicle as shown. 5-30 A. Wing Nut B. Wheel Blocks C.
Store the tire under the rear of the vehicle in the spare tire carrier. To store the tire, do the following: 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed downward and to the rear. 2. Tilt the retainer downward and through the wheel opening. Make sure that the retainer is fully seated across the underside of the wheel. 3. Attach the wheel wrench and extensions together. Insert the hoist end through the hole in the rear bumper and into the hoist shaft. 4.
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” and “Loading Your Vehicle” in the Index for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see “Changing a Flat Tire” in the Index.
If You’re Stuck: In Sand, Mud, Ice or Snow NOTICE: In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution. Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.
Rocking Your Vehicle To Get It Out Using the Recovery Hooks First, turn your steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear.
CAUTION: These hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back. NOTICE: Never use the recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.
Section 6 Service and Appearance Care Here you will find information about the care of your vehicle. This section begins with service and fuel information, and then it shows how to check important fluid and lubricant levels. There is also technical information about your vehicle, and a part devoted to its appearance care.
Service Doing Your Own Service Work Your dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index.
CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. D Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. D Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
Gasoline Specifications California Fuel It is recommended that gasoline meet specifications which were developed by the American Automobile Manufacturers Association and endorsed by the Canadian Vehicle Manufacturers’ Association for better vehicle performance and engine protection. Gasolines meeting these specifications could provide improved driveability and emission control system performance compared to other gasolines.
To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air.
Filling Your Tank CAUTION: Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline. While refueling, hang the fuel cap by the tether using the hook located on the inside of the filler door. To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap is located behind a hinged door on the driver’s side of the vehicle.
CAUTION: If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way. Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Vehicle” in the Index.
Filling a Portable Fuel Container CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: D Dispense gasoline only into approved containers. D 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.
To open the hood, do the following: Hood Release The hood release is located inside the vehicle on the lower left side of the instrument panel. 1. Pull out on the hood release handle. 2. Then go to the front of the vehicle and pull up on the secondary hood release, located near the center of the grille. 3. Lift the hood. Before closing the hood, be sure all the filler caps are on correctly. Pull down the hood and close it firmly.
Engine Compartment Overview When you lift the hood on the VORTEC 6000 V8 engine, you’ll see: 6-10
A. Engine Air Cleaner/Filter B. Coolant Surge Tank C. Air Cleaner/Filter Restriction Indicator D. Engine Oil Dipstick E. Engine Oil Fill Cap F. Automatic Transmission Dipstick G. Fan H. Remote Negative (-) Terminal (GND) Engine Oil If the CHECK ENG OIL LEVEL light appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see “CHECK ENG OIL LEVEL” in the Index. You should check your engine oil level regularly; this is an added reminder. I.
Checking Engine Oil It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick has a yellow looped handle and is located on the passenger’s side of the vehicle. See “Engine Compartment Overview” in the Index for more information on location. 6-12 Turn off the engine and give the oil several minutes to drain back into the oil pan.
When to Add Engine Oil If the oil is at or below the ADD mark, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use. For engine oil crankcase capacity, see “Capacities and Specifications” in the Index. The engine oil fill cap is located on the passenger’s side valve cover. NOTICE: See “Engine Compartment Overview” in the Index for more information on location. Don’t add too much oil.
What Kind of Engine Oil to Use Oils recommended for your vehicle can be identified by looking for the starburst symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this starburst symbol. If you change your own oil, be sure you use oil that has the starburst symbol on the front of the oil container.
As in the chart shown previously, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0 F (-18 C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50. _ _ NOTICE: Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.
How to Reset the CHANGE ENGINE OIL Message What to Do with Used Oil The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system. Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer.
Engine Air Cleaner/Filter The air cleaner/filter assembly has an indicator that lets you know when the engine air cleaner/filter is dirty and needs to be serviced. The air cleaner/filter indicator is located on the air cleaner cover. See “Engine Compartment Overview” in the Index for more information on location. See “Owner Checks and Services” in the Index to determine when to check the indicator. The service window A with the percentage scale shows the amount of engine air cleaner/filter life used.
Refer to the Maintenance Schedule to determine when to replace the engine air cleaner/filter. See “Owner Checks and Services” in the Index. CAUTION: To replace the engine air cleaner/filter do the following: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned.
Passenger Compartment Air Filter Your vehicle is equipped with a passenger compartment air filter. The filter is located under the instrument panel, below the glove compartment. Your vehicle may or may not be equipped with an access panel. 2. Reach under the instrument panel towards the front of the vehicle and pull downward on the filter retaining bracket. To replace the passenger compartment air filter, do the following: 1. If your vehicle does not have an access panel, skip this step.
Automatic Transmission Fluid How to Check When to Check and Change Because this operation can be a little difficult, you may choose to have this done at the dealership service department. A good time to check your automatic transmission fluid level is when the engine oil is changed. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
To get the right reading, the fluid should be at normal operating temperature, which is 180_F to 200_F (82_C to 93_C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50_F (10_C). If it’s colder than 50_F (10_C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes.
Then, without shutting off the engine, follow these steps: The red transmission dipstick handle with this symbol is located at the rear of the engine compartment, on the passenger’s side. See “Engine Compartment Overview” in the Index for further information on location. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT area, or cross-hatched area for a hot check. 1.
How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid 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. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill.
How to Check Lubricant What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index. 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 To get an accurate reading, the vehicle should be on a level surface.
How to Check Lubricant What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index. Front Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See “Scheduled Maintenance Services” in the Index. Automatic Transfer Case (A) Fill Plug (B) Drain Plug To get an accurate reading, the vehicle should be on a level surface.
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 may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 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.
Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index.
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOLR coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant The coolant surge tank is located on the passenger’s side of the vehicle in the engine compartment. CAUTION: Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap -- even a little -- when the engine and radiator are hot. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FULL COLD mark.
Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the surge tank, but only when the engine is cool. Coolant Surge Tank Pressure Cap The coolant surge tank pressure cap must be fully installed on the coolant surge tank. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. When replacing the pressure cap, make sure it is hand-tight.
Power Steering Fluid How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. See “Engine Compartment Overview” in the Index for reservoir location.
Brakes Brake Fluid of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.
Checking Brake Fluid What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to “Recommended Fluids and Lubricants” in the Index. Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. CAUTION: You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN.
NOTICE: D Using the wrong fluid can badly damage D brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.
Brake linings should always be replaced as complete axle sets. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.” Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is complex.
Vehicle Storage Bulb Replacement If you’re not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your battery from running down. For any bulb changing procedure not listed here, contact your dealer. CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear and cracking. See “Wiper Blade Check” in the Index for more information. Replacement blades come in different types and are removed in different ways. For proper type and length, see “Normal Maintenance Replacement Parts” in the Index. To replace the windshield wiper blade assembly, do the following: 1. Lift the wiper arm and turn the blade until it is facing away from the windshield. 2.
Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your Warranty booklet for details. CAUTION: (Continued) D Underinflated tires pose the same danger as CAUTION: Poorly maintained and improperly used tires are dangerous. D Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident.
Inflation -- Tire Pressure The Certification/Tire label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench/hoist shaft to tighten the cable.
When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. You need a new tire if any of the following statements are true: D You can see the indicators at three or more places around the tire. D You can see cord or fabric showing through the tire’s rubber.
CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. If your vehicle has 17 inch road tires (those originally installed on your vehicle) it is all right to drive with the 16 inch spare tire that came with your vehicle.
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 1/2) 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.
Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. CAUTION: Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.
Used Replacement Wheels CAUTION: Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Tire Chains CAUTION: Don’t use tire chains. There’s 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.
Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside.
D Carefully scrape off any excess stain. D Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. D If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set. Using Cleaner on Fabric 1. Vacuum and brush the area to remove any loose dirt. 2. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. 3. Follow the directions on the container label. 4.
Cleaning Vinyl Cleaning the Top of the Instrument Panel Use warm water and a clean cloth. Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. D Rub with a clean, damp cloth to remove dirt. You may have to do it more than once.
Care of Safety Belts Keep belts clean and dry. CAUTION: Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See “Appearance Care and Materials” in the Index.
Weatherstrips Washing Your Vehicle Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See “Recommended Fluids and Lubricants” in the Index. The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. See “Appearance Care and Materials” in the Index. Your vehicle has a “basecoat/clearcoat” paint finish.
Cleaning Aluminum Wheels (If Equipped) Keep your 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. The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels.
Finish Damage Chemical Paint Spotting Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface.

Vehicle Identification Number (VIN) Engine Identification The 8th character in your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts. Service Parts Identification Label You’ll find this label located in the glove box. It’s very helpful if you ever need to order parts. On this label is: This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side.
Electrical System Windshield Wipers Add-On Electrical Equipment The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed. NOTICE: Don’t add anything electrical to your vehicle unless you check with your dealer first.
Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems. Instrument Panel Fuse Block The fuse block access door is on the driver’s side of the instrument panel at the end. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.

Section 7 Maintenance Schedule This section covers the maintenance required for your vehicle. Your vehicle needs these services to retain its safety, dependability and emission control performance.
Introduction Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle.
How This Section is Organized This maintenance schedule is divided into five parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs. CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured.
Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways.
Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after 100,000 miles (166 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) and 200,000 miles (332 000 km) should be repeated at the same intervals after 150,000 miles (240 000 km) and 200,000 miles (332 000 km) for the life of this vehicle. See “Owner Checks and Services” and “Periodic Maintenance Inspections” following. Footnotes [ The U.
Scheduled Maintenance Engine Oil and Chassis Lubrication Scheduled Maintenance Change engine oil and filter as indicated by the GM Oil Life Systemt (or every 12 months, whichever occurs first). Reset the system. 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. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably.
