Section 1 Seats and Restraint Systems Here you’ll find information aboutthe seats in your vehicle and how to use your safety belts properly. You can also learn about some thingsyou should nut do with air bags and safety belts.
Seats and Seat Controls Power Driver’s Seat This section tells you about the seats -- how to adjust them, and fold them up and down. Manual Passenger’s Seat Move the lever under the front of the passenger’s seat up to unlockit. Slide the seat to where you want it. Then release the leverand try to move the seat with your body to make sure the seat is locked into place. 1-2 Horizontal Control: Raise the front of the seat by raising the forward edge of the button.
Moving the whole button up or down raises or lowers the whole seat. Vertical Control: Move the reclining front seatback rearward by moving the button toward the rear of the vehicle. Move the seatback forward by moving the button toward the front of the vehicle. Power Lumbar Control Heated Front Seats This control is located on the side of the seat. This feature will quickly heat the lower cushion and lower back of the driver and front passenger seats for added comfort.
~ RecliningFrontSeatback To adjust the right front passenger’s seatback, lift the lever on the outer side of the seat. Release the lever to lock the seatback where you want it. Pull up on the lever and the seat will go to an upright position. 1-4 But don’t have a seatback reclined if your vehicle is moving.
A CAUTION: Sitting ina reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their jobwhen you’re reclined like this. The shoulder belt can’t do itsjob because it won’t be against your body. Instead, itwill be in front of you. In a crashyou could go into it, receiving neckor otherinjuries. 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.
I Rear Seats Your vehicle has a folding rear seatwhich lets you fold the seatbacks down formore cargo space. To return the head restraints to the upright position, reach behind the seats and pull the head restraint up until it locks into position. The rear seat release handles are onthe rear of the seatbacks. Push back on the seatbacks as you pull up on the handles. The head restraint will automatically fold out of the way when the seatback is folded down.
Safety Belts: They’re for Everyone A CAUTION: 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 Supplemental Inflatable Restraint (SIR), or air bag system. A 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 thingsinside the vehicle or be ejected from it.
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.

Here Are Questions Many People Ask About Safety Belts-- and the Answers &.. Won't I be trapped in the vehicle afteran 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. A: You ctxrld be -- whether you're wearing a safety belt or not. But you can unbuckle a safety belt, even if you're upside down.
@ 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.
Lap-Shoulder Belt The driver has a lap-shoulder belt. Here’s how to wear it properly. 1. Close and lock the door. 2. Adjust the seat (to see how, see “Seats” in the Index) so you can sit up straight. 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 4.
5. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you'd be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.This could cause serious or evenfaal injuries. The shoulder belt should go over the shoulder and across the chest.
What’s wrong with this? I 1 You can be seriously hurtif your shoulder belt is too loose. In a crash, you wouldmove 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.
@ What’s wrong with this? You can be seriously injured if your belt is buckled in thewrong 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 internalinjuries. Always buckle your belt into thebuckle nearest you. I A: 1 1 I I I I The belt is buckled in the wrong place.
What's wrong with this? You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would movetoo 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 asstrong as shoulder bones. You could also severely injure internal organs like your liver or spleen. 'A A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
@ What’s wrong with this? You can be seriously injured bya twisted belt. In of the a crash, you wouldn’t have the full width belt to spread impact forces.If a belt is twisted, make it straightso 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 injuredif they don't wear safety belts. To unlatch the belt, just push the button on the buckle. The belt shouldgo back outof the way. Before you close thedoor, be sure the beltis out of the way. If you slarn the dooron 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.
Here are themost important things to know about the air bag system: I You can be severely injured or killed in a crash if you aren’t wearing your safety belt even if you have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejectedfrom it. Air bags are “supplemental restraints” to the safety belts. All air bags even reduced-force air bags are designed to work with safety belts,but don’t replace them.
rChildren - who ar ~p against,or very close to, an air bag when it inflates can be seriously injured or killed. This is true even though your vehicle has reduced-force frontal air bags. Air bags plus lap-shoulder belts offer the best protection for adults, butnot 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.
How the Air Bag System Works The right front passenger’s airbag is inthe instrument panel on the passenger’s side. Where are the airbags? The driver’s airbag is in the middle of the steering wheel.
When should an airbag inflate? I 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. The path of an inflating air bag mustbe kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or putanything on the steering wheel hub or on or near any other air bag covering. An air bag is designed to inflate in a moderate to severe frontal or near-frontal crash.
What makes an air bag inflate? What will you see after an air bag inflates? In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. The sensing system triggers a release of gas fromthe inflator, which inflates the air bag. The inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel and in the instrument panel in front of the right front passenger.
Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag syste,m won’t be there to help protect you i n another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts.
Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There areparts 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 GM 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.
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.
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 beltis pulled out all the way, it will lock.If it does, let it go back all the way and start again. If the belt is not long enough, see “Safety Belt Extender” 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 quicklyif you ever had to. 3. To make the lap part tight, pull down on the buckle part.
The safety belt locks if there's a sudden stop or a crash. The safety belt also locks if you pull the belt very quickly out of the retractor. ou can be seriously hurtif your shoulder beltis too loose. Ina crash, you would move forward too much, which could increase injury. The shoulder belt shouldfit 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.
There is one guide for each outside passenger position in the rear seat.To provide added safety belt comfort for children who have outgrown child restraints and for smaller adults, the comfort guides may be installed on the shoulder belts.Here’s how to installa comfort guide and use the safety belt: To unlatch thebelt, just push the button on the buckle.
2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edgesof the belt into the slotsof the guide. 1-32 3. Be sure that the belt is not twisted and it lies flat. The elastic cordmust be under the belt and the guide on top.
4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guides, squeeze the belt edges togetherso that you can take them out from the guides. Pull the guide upward to expose its storage clip, and then slide the guide onto the clip.
Center Rear Passenger Position Lap Belt When you sit in the center rear seating position, you have a lap safety belt which has a retractor. 1. Pick up the latch plate andpull the belt across you. Don't let it get twisted. 2 . Push the latch plate intothe buckle until it clicks. Pull up on the latch plate tomake sure it is secure.
3. Feed the lap belt into the retractor to tighten it Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. Neither the distance traveled nor the age and size of the traveler changes the need. for everyone, t o use safety restraints. I n fact. the law i n every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle. Sm,-'ler Childre ~ - -d Ba '- A CAUTION: 4.
- Smaller children and babies should always be restrained in a child or infant restraint. The instructions for the restraintwill say whether it is the right type and size for your child. A very young child’s hip bones are so small that a regular belt might not stay low on the hips, as it should. Instead, thebelt will likely beover the child’s abdomen. In a crash, thebelt would apply force righton the child’s abdomen, which could cause serious or fatal injuries.
r at only 25mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on your arms. The baby would be almost impossible to hold. Secure the baby in an infant restraint. Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much until a crash. Duringa crash a baby will become so heavy you can’t hold it.
Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints. @ What are the different types ofadd-on child restraints? A: Add-on child restraints are available in four basic types. When selecting a child restraint, take into consideration not only the child’s weight and size, but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.
. 8 : . - . . , 7 . . . I . .. ., . A rear-facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear-facing infant restraints are designed forinfants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a crash. Some infant seats come in two parts -- the base stays secured in the vehicle and the seat part is removable.
A forward-facing child restraint (C-E) positions a child upright to face forwardin the vehicle. These forward-facing restraints are designed to help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age. One type, a convertiblerestraint, is designed to beused either as a rear-facing infant seat or a forward-facing child seat.
A booster seat (F, G) is designed for children who are about40 to 60 lbs. (18 to 27 kg) and aboutfour to eight yearsof age. It’s designed to improve the fit of the vehicle’s safety belt system. Booster seats with shields use lap-only belts; however, booster seats without shields use lap-shoulder belts. Booster seats can also help a child to see out the window.
When choosing a child restraint, be sure the child restraint is desigmd to be used in a vehicle. If i t 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 i n a booklet, or both. These restraints use the belt system i n your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.
If your child restraint has a top strap, it should be anchored. Anchor bracketsfor the rear outside seat positions are located on the floor in the cargo area. Don’t use the front set of tie-down brackets. Anchor the top strap to the rearmost bracket on the same side of the vehicle as the child restraint. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself.
Securing a Child Restraint in a Rear Outside Seat Position 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.
4. Pull the restof the shoulder belt all theway out of the retractor to ‘set the lock. 5. To tighten the belt, feed the shoulder belt back into on the child the retractor while you push down restraint. If you’re usinga forward-facing child restraint, you may find it helpfulto use your knee to push down on the child restraintyou as tighten the belt. 6. Push and pull the child restraint in different directions to be sureit 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 towork for an adult Securing a Child Restraint in the Right Front Seat, Position or larger childpassenger. Center Seat Position Your vehicle hasa right front passenger air bag. Never put a rear-facing child restraintin this seat.Here’s why: Don’t use child restraints in this position. The restraints won’t work properly.
A CAULON: A child in a rear-facing child restraint canbe seriously injured orkilled if the right front passenger’s air bag inflates, even though your vehicle has reduced-force frontalair bags. This is because the back of the rear-facingchild restraint would be very close to the inflatingair bag. Always secure a rear-facingchild restraint in the rearseat. You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one.
P e 4. Buckle the belt. Make sure the release button is positioned so you would be ableto unbuckle the safety belt quicklyif you ever had to. 1-48 5. Pull the restof 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. You may find it helpful to use your knee to push down Children who have outgrown child restraints should on the child restraint as you tighten the belt. wear the vehicle’s safety belts. I . Push and pull the child restraint in different If you have the choice, a child should sit next to a directions to be sure it is secure.
Accident statistics showthat children are safer if they are restrained in the rear seat. But they need to use the safety beltsproperly. Children who aren’t buckledup can be thrown out in a crash. Children who aren’t buckled upcan strike other people whoare. Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, thetwo children canbe crushed together and seriously injured. A belt must be used by only oneperson at a time.
A CAUTION: Never do this. Here achild issitting in a seat that has a lap-shoulder belt, but the shoulderpart is behind the child. If the child wears thebelt in thisway, in a crash thechild might slide under the belt. The belt’s force would then be applied righton the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt on the hips,just touching should be worn low and snug 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 areworking properly. Look for any other loose ordamaged 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 If you’ve had a crash, doyou need new belts? After a very minor collision, nothing may be necessary. But if the belts were stretched, asthey would be if worn during a more severe crash, then you need new belts. To help avoid personal njury, belt assembly must )e replaced if this vehicle is n a collision or if “Replace 3elt” appears below.See 3wner’s Manual formore information.

Section 2 Features and Controls Here you canlearn 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 tellif you everything is working properly -- and what to doif you have a problem.
Keys A CAUTION: Leaving young 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 power windows or other controls or even make the vehicle move. Don't leave the keys ina vehicle with young children.
This vehicle has one double-sided key for the ignition and door locks. It will fit with either side up. The key code number tells your dealer or a qualified locksmith how to make extra keys. Keep this number in a safe place. If you lose your keys, you’ll be able to have 1ew ones madeeasily using this number. Your selling iealer should also have this number. NOTICE: When a new vehicle is delivered, the dealer provides the owner with a pair of identical keys and a key code number.
There are several ways to lock and unlock your vehicle. Door Locks You can use the Keyless Entry System. You can use your key to unlock your door from the outside. I Unlocked doors can be dangerous. Passengers especially children can easily open the doors and fallout. When a door is locked, the inside handle won't open it. Outsiders can easily enter through an unlocked door when you slowdown or stop your vehicle.
Power Door Locks Rear Door Security Lock With this feature,you can lock the rear doors so they can’t be openedfrom the inside by passengers. Move the lock up to lock the doors and downto release the door locks. Lockout Prevention The power door lock switch is located on the armrest. Remove the ignition key and press LOCK to lock all the doors at once.
Leaving Your Vehicle If you are leaving the vehicle, take your key, open your door and set the locks from inside.Then get out and close the door. Keyless Entry System You can lock and unlock your doors or liftgate from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.
Operation Matching Transmitter(s) To Your Vehicle UNLOCK: Pressing this button once will unlock the Each remote keyless entry transmitter is coded to prevent another transmitter fromunlocking your vehicle. If a transmitter is lost or stolen, areplacement 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.
Battery Replacement To replace the battery in the keyless entry transrnitter: Under normal use, the battery in your remote keyless entry transmitter should last about two years. I You can tell the battery is weak if the transmitter won’t work at the normal range in any location. I f you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery. NOTICE: When replacing the battery, use care not to touch any of the circuitry.
Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. To resynchronize your transmitter, stand close to your vehicle and press and hold the LOCK and UNLOCK buttons on the transmitter at the same time for seven seconds.
Liftgate Release Remote Liftglass Release To release the liftgate or liftglass, you may use the Keyless Entry System described earlier. The liftglass can be opened if the driver’s door is unlocked. 1 This button on the passenger’s side of the steering columnallows you to release the liftglass from inside the vehicle. To open the liftglass only, press the button and pull up on the handle. Your shift lever must be in PARK (P) or NEUTRAL (N) for the release to work.
Key in the Ignition Content Theft-Deterrent If you leave your vehiclewith the keys inside, it’s an easy target for joy riders or professional thieves -- so don’t do it. When you park your vehicle and open the driver’s door, you’ll hear a chime remindingyou to remove your key from the ignitionand take it with you. Always do this. Your steering wheel will be locked, andso will your ignition and transmission. And remember to lock the doors.
Remember, the theft-deterrent system won‘t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if’ the alarm has been set off.
During normal operation, the SECURITY light will go off after the engine is started. If the engine stalls and the SECURITY light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Remember to release the key from the START position as soon as the engine starts. If the engine does not start after three (3) tries, the vehicle needs service. If you are driving and the SECURITY light comes on, you will be able to restart the engine if you turn the engine off.
Ignition Positions Use the key to turn the ignition switch to five different positions. C I NOTICE: Don’t operateaccessories in the ACCESSORY position for long periodsof time. Prolonged operation of accessories in the ACCESSORY position could drain your battery and prevent you from starting your vehicle. LOCK (B): This position locks your ignition, steering wheel and transmission. It’s a theft-deterrent feature. You will only be able to removeyour key when the ignition is turned to LOCK.
NOTICE: If your key seems stuck inLOCK and you can’t turn it, be sure you are using the correctkey; if so, is it all the way in? If it is, then turn the steering wheel left and right while you turn the key hard. But turnthe key onlywith your hand. Using a tool to force it could break thekey or the ignition switch. If none of this works, then your vehicle needs service.
I NOTICE: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. Andthe excessive heat can damage your starter motor. 2. If it doesn’t start right away, hold your key in START. If it doesn’t start in 10 seconds, push the accelerator pedal all the way down for five more seconds, unless it starts sooner. 3. If your engine still won’t start (or starts but then stops), wait 15 seconds and start over.
To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is located on the driver’s side of the engine compartment, behind the underhood fuse block. 3. Plug it into a normal, grounded 110-volt AC outlet. % CAUTION: 4. Before starting the engine,be sure to unplug and store the cord as it was before to keep it away from moving engine parts.If you don’t, it could be damaged.
Automi ic Transmission Operation There are several different positions for your shift lever. PARK (P): This locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. 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.
DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. 0 Going less than about 35 mph (55 krdh), push your accelerator pedal about halfway down. Going about 35 mph (55 krdh) or more, push the accelerator all the way down. You’ll shift down to the next gear and have more power.
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. I f the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into FIRST (1) until the vehicle is going slowly enough. NOTICE: 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.
NOTICE: Shifting Into PARK (P) L!h C A U T L .: Driving with the parking brake on can cause your rear brakes tooverheat. You may have to replace them,and you could also damage other parts of your vehicle. I It can be dangerous to get out of your vehicle if the shiftlever is not fully in PARK (P) with the parking brakefirmly set. Your vehiclecan roll. If you have left the engine running, thevehicle can move suddenly. You or otherscould be injured.
2. Move the shift lever into PARK (P) position like this: Leaving Your Vehicle With the Engine Running 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 brakefirmly 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. Hold in the button on the lever.
Torque Lock Shifting Out ofPark (P) If you are parking on ahill 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 outof 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 IntoPARK (P)” in the Index.
P -ing Over nqs That Burn 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. 2-24 Engine Exhaust 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: Your exhaust system sounds strange or different. Your vehicle gets rusty underneath. 0 Your vehicle was damaged in a collision.
Running Your Engine While You’re Parked It’s better not to park with the engine running. Butif ever you have to, here are some thingsto know. A CAUTION: Idling theengine with the airsystem control off could allowdangerous exhaust into your vehicle (seethe earlier Caution under “Engine Exhaust”).

Voltmeter Gage 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 engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power.
Brake System Warning Light When the ignition is on, the brake system warning light will come on when you set your parking brake. The light will stay on if your parking brake doesn’t release fully. If it stays on after your parking brake is fully released, it means you have a brake problem. Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well.
Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal. If the light stays on, or comes on when you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on, you don’t have anti-lock brakes and there’s a problem with your regular brakes.

SERVICE ENGINE SOON United States Canada Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems.
If the Light Is Flashing I f the Light Is On Steady The following may prevent more serious damage to your vehicle: You may be able to correct the emission system malfunction by considering the following: Reducing vehicle speed. Did you recently put fuel into your vehicle? Avoiding hard accelerations. If so, reinstall the fuel cap, making sure to fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed.
Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel (see "Fuel" in the Index). Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stallingwhen you put the vehicle into g a r , misfiring, hesitation on acceleration or stumbling on acceleration.

See “Mode Knob - Automatic Operation” earlierin this section. +0 /J PANEL: This setting directs most of the air through the instrument panel outlets and a small amount through the floor outlets.
Air Conditioning Heating On hot days, open the windows long enough tolet hot inside air escape. Thisreduces the time it takes for your vehicle to cool down. Then keep yourwindows closed for the air conditioner to work its best. The heater works best if you keep your windows closed while using it. On cold days, use HEATER with the temperature knob turned to the right. BLEND is useful in cool weather when you have fog or ice on the windshield or side windows.
Ventilation Tips 0 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. e When you enter a vehicle in cold weather, move the fan control to the right to the highest setting for a few moments before driving off. This helps clearthe intake ducts of snow and moisture, and reduces the chance of fogging the inside of your windows.

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.
Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor tothe highway death toll, claiming thousands of victims every year. The obvious way to solve this highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is ”too much” if the driver plans to drive? It’sa lot less than many might think. Although it depends on each person and situation, here is some general information on the problem.
woman generally will reach a higher BAC level than a miin of her same body weight when each has the same number of drinks. The law i n many U S . states sets the legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limit is 0.08 percent. I n some other countries, it's even lower. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.10 percent after three to six drinks (in one hour).
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 avoidthe 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 togo. They are the brakes, the steering and the accelerator. All three systems have to do their work at theplaces where the tires meet the road. Braking action involves perception time and reaction time. First, you have to decide to push onthe brake pedal. That’s perception time. Thenyou have to bring up your foot and do it. That’s reaction time. Average reaction time is about 314 of a second.
And, of course, actual stopping distances vary greatly with the surface of the road (whether it‘s pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied. 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.
The anti-lock system can change the brake pressure faster than any driver could. The computeris programmed to make the most of available tire and road conditions. Here’s how anti-lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here’s what happens with ABS. A computer senses that wheels are slowing down.
Re,member: 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. Using Anti-Lock Don‘t pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you.
The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at which the curve is banked, and YOLK speed. While you’re in a curve, speed is the one factor you can control. Suppose you’re steering through a sharp curve. Then you suddenly accelerate. Both control systems -- steering and acceleration -- have to do the.ir work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control.
Load Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you're driving. OFF - ROAD RECOVE 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. The fac.
Passing The driver of a vehicle about to pass another on a two-lane highway waits for justthe 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.
0 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 farenough ahead of the passed vehicle to seeits front in your inside mirror, activate your right lane change signal and move back into the right lane. (Remember that your right outside mirror is convex. The vehicle you just passed may seem to be farther away fromyou than it really is.) Try not to pass more than one vehicle at a time on two-lane roads.
If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel or other material is o n the road. For safety, you‘ll want to slow down and adjust your driving to these conditions.
Off-Road Driving withYour GM Four-Wheel-DriveVehicle Also, see "Anti-Lock Brakes" in the Index. Off-road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. "Off-roading" means you've left the great North American road system behind. Traffic lanes aren't marked. Curves aren't banked. There are no road signs. Surfaces can be slippery, rough, uphill or downhill. In short, you've gone right back to nature. Off-road driving involves some new skills.
Environmental Concerns 0 0 0 Cargo on the load floor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the topof the seatbacks. Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. Heavy loads on the roof raise thevehicle’s center of gravity, making it more likely to roll over.
Traveling to Remote Areas It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads. 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.
Scanning the Terrain Off-road driving can take you over many different kinds of terrain. You need to be familiar with the telrain and its many different features. Here are some things to consider. S~lr$uceConditions. Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice. Each of these surfaces affects the steering, acceleration and braking of your vehicle in different ways.
Driving on Off-Road Hills Off-road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and can't do. There are some hills that simply can't be driven, no matthow well built the vehicle. - Many hills are simply too steep for any vehicle. If you drive up them, you will stall.If you drive down them, youcan't control your speed.If you drive across them,you will roll over.You could be seriously injured or killed.
Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. Use a low gear and get a firm gripon the steering wheel. 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. 0 Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route. Turning or driving across steep hills can be dangerous.
What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? A: 0 0 0 0 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: Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R).
Driving Downhill A When off-roading takes you uownhill, you'll want to consider a number of things: 0 How steep is the downhill'?Will I be able to maintain vehicle control? 0 What's the surface like'? Smooth'?Rough'? Slippery'? Hard-packed dirt'? Gravel? 0 Are there hidden surface obstacles'! Ruts? Logs? Boulders'? 0 What's at the bottom of the hill'! Is there a hidden creek bank or even a river bottom with large rocks? If you decide you can go down a hill safely.
Q.' A: 0 0 It's much nm-e likely to happen going uphill. But if it happens going downhill, here's what to do. Stop your vehicle by applying the regular brakes. Apply the parking brake. Shift to PARK ( P ) and. while still braking. restart the engine. Shift back to a l o w gear, release the parking brake, and drive straight d6wn. If the engine w o n ' t start, get o u t and get lelp. Driving Across an Incline Sooner or later, an off-road trail will probab y go across the incline of a hill.
Stalling on an Incline Driving across an incline that’s too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about thesteepness of the incline, don’t drive across it. Find another route instead. What if I’m driving across an incline that’s not too steep, but I hit some loosegravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill.
Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high)side of the vehicle and stay well clear of the rollover path. 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.
Driving in Water Light rain causes n o special off-road driving problems. But heavy rain can mean flash flooding, and flood waters demand extreme caution. Find o u t 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.
Your vehicle will require more frequent service due to off-road use. Refer to the Maintenance Schedule for additional information. Drivin at Night Here are some tips on night driving. 0 0 0 0 0 Drive defensively. Don't drink and drive. Adjust your inside rearview mirror to reduce the c"lare 2 from headlamps behind you. Since you can't see as well, you may need to slow down and keep more space between you and other vehicles. Slow down, especially on higher speed roads.
You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with Driving in Rainand on Wet Roads misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlarnps. Keep your windshield and all the glass oi=ryourvehicle clean -- inside and out.
The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking. It’s wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid.
Hydroplaning 1)riving Through Deep Standing W Fr ’ Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you’re going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road. NOTICE: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your is slightly engine.
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: 0 Know the best way t o get to where you are going. Get a city map and plan your trip into an unknownpart of the city just as you would for a cross-country trip. 0 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 yourspeedometer’ 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. 0 WincJsl~ieldWcrshc~r-Fluid: Is the reservoir full? Are all windows clean inside and outside? 0 Wiper Blcrdes: Are they in good shape? 0 Fuel, Elzgirze Oil, Other Flr.
Highway Hypnosis aLL - - ountain 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.
0 0 Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. Theseparts can work hard on mountain roads. /I\ CAC rION: 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. You could crash.
You may see highway signs on mountains that warn of special problems. Examples are long grades, passing or no-passing zones, a falling rocks area or winding roads. Be alert to these and take appropriate action. Winter Driving Here are solne tips for winter driving: Have your vehicle in good shape for winter. You may want to put winter emergency supplies in your vehicle.
Whatever the condition -- smooth ice, packed, blowing or loose snow -- drive with caution. 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 Tie a red cloth t o your vehicle to alert police that you’ve been stopped by the snow. 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 o r tuck under y o ~ clothing ~r to keep warm. If you are stopped by heavy snow, you could be i n a serious situation.
Snow can trap exhaust gases under your vehicle. This can causedeadly CO (carbon monoxide) gas to get inside.C O could overcomeyou 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 baseof 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. of the Open a window justa little on the side vehicle that’s away from the wind. Thiswill help keep CO out.
Loading Your Vehicle 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.
Using heavier suspension componentsto get added durability mightnot change your weight ratings. Ask your dealer to helpyou load yourvehicle the right way. A CAUmmdN: - NOTICE: Your warranty does not cover parts or components that fail because of overloading. If you put things inside yourvehicle -- like suitcases, -- they will go as fast tools, packages, or anything else as the vehicle goes. If you have to stopor turn quickly, or if there is a crash, they’ll keep going.
Payload The payload capacity is shown on the CertificationRire label. This is the maximum load capacity that your vehicle can carry. Be sure to include the weight of the occupants as part of your load. If you added any accessories or equipment after your vehicle left the factory, remember to subtract the weight of these things from the payload. Your dealer can help you with this.
Add-on Equipment When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure t o weigh your vehicle before you buy and install the new equipment. I NOTICE: Your warranty doesn’t cover parts or components that fail because of overloading. Towing a Trailer A CAUTION: If you don’t use the correctequipment and drive properly, you can lose control when you pull a trailer.
Every vehicle is ready for some trailer towing. If yours was built with trailering options, as many are, it’s ready for heavier trailers. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That’s the reason for this part. In it are many time-tested, important trailering tips and safety rules.
Weight of the Trailer Weight of the Trailer Tongue How heavy can a trailer safely be? 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.
1 TotalWeight on Your Vehicle’sTires Be sureyour vehicle’s tires are inflated to the upper limit for coldtires. You’ll find these numbers on the CertificatiodTire label on the driver’s door edge, above the door latch, or see “Tire Loading” in the Index. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches A B It’s important to have the correct hitch equipment.
Safety Chains You should always attach chains between y o ~ vehicle ~r and yo~lrtrailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer o r by the trailer manufxturer. Follow the manufacturer's recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig.
Driving with a Trailer A CAUTION: If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could comeinto yourvehicle. You can’t see or smell CO. It can cause unconsciousness or death. (See ‘(EngineExhaust” in the Index.) To maximize your safety when towinga trailer: 0 Have yourexhaust system inspectedfor leaks, and makenecessary repairs before starting on your trip. 0 Keep the rear-mostwindows closed.
Passing Turn Signals When Towing a Trailer You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. When you tow a trailer, your vehicle has to have extra wiring and a heavy-duty turn signal flasher. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left.
Driving On Grades Parking on Hills Reduce speed and shift to a 1owe.r gear Iwfow you start down a long or steep downgrade. If you don’t shift down. you might have to use your brakes so much that they would get hot and no longer work well. You really should not park your vehicle, with a trailer attached. on a hill. If‘ something goes wrong, your rig could start t o 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: 0 Start your engine; Shift into a gear; and 0 Release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When TrailerTowing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule formore on this.
Trailer Wiring Harness The heavy-duty trailer wiring is an eight-wire harness assembly. The harness is stored under the vehicle, on the driver’s side corner framerear crossmember. The heavy-duty trailer wiring has a 30-amp feed wire with an in-line fuse located by the junct.ion block. See “Fuses and Circuit Breakers” in the Index. The harness does not have a cannector and should be wired by a qualified electrical technician.
Section 5 Problems on the Road Here you’ll find what to do about some problems that can occur on the road.
I’ :---d Warning Flashers Press the button on top of the steering column all the way down to make your front and rear turn signal lamps flash on and off. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. To turn off the flashers, press the button until the first click and release. Your hazard warning flashers let you warn others. They also letpolice know you have a problem. Your front and rear turn signal lampswill 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. But please use the following steps to do it safely. ’ Batteries canhurt you. They c..-- be dangerous because: They contain acid that can burn you. They contain gas that can explode or ignite. They contain enough electricity to burn you. If you don’t follow these steps exactly, someor 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. 4. Open both hoods and locate the batteries. Find the positive (+) and negative (-) terminals on each battery. A To avoid the possibility of the vehicles rolling, set the parking brake firmly on each vehicle.
5 . Check that the jumper cables don’t have loose or missing insulation. If they do. you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) and negative (-) will go to a metal engine part. Don’t connect positive (+) to negative (-) or you’ll get a short that would damage the battery and maybe other parts too. 6.
9. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. 1 12. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less. 10. Now start the vehicle with the good battery and run the engine for awhile. 1 1. Try to start the vehicle with the dead battery.
Towing Your Vehicle Try to have a GM dealer or aproressional towing service tow yourvehicle. See "Roadside Assistance" in the Index. If your vehicle has been changed since itwas factory-new by adding things like fog lamps, aero skirting, or special tires and wheels, these instructions may not be correct. Before you do anything, turn on the hazard warning flashers. When you call, tell the towing service: 0 That your vehicle has four-wheel drive. 0 The make, model and year of your vehicle.
1 Remove the wood trim panel surrounding the base of the shift lever. 2. Reach inside the console and find the white solenoid lever. I JTION: A vehicle can fall from a car carrierif it isn’t adequately secured. This can cause a collision, serious personal injury and vehicle damage. The vehicle should be tightly secured with chains or steel cables before it is transported. Don’t use substitutes (ropes, leather straps, canvas webbing, etc.) that can be cut by sharp edges underneath the towed vehicle.
~~ IOW . ~ Towing Limits - - 35 mph (55 km/h), 50 miles (80 k m ) You must use a towing dolly under the rear wheels when towing from the front. NOTICE: Do not tow with sling-type equipment or fascia/fog lamp damage will occur. Use wheel-lift or car-carrierequipment. Additional ramping may be required for car-carrier equipment. Use safety chains and wheel straps. Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle to groundor vehicle to wheel-lift equipment.
NOTICE: Do not tow with sling-type equipment or rear bumper valance damage will occur. Use wheel-lift or car-carrierequipment. Additional ramping may be required for car-carrierequipment. Use safety chains and wheel straps. Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle to ground or vehicle to wheel-lift equipment. To help avoid damage, install a towing dollyand raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment.
Engine Overheating You will find a coolant temperature gage on your vehicle's instrument panel. See "Gages" in the Index. If Steam Is Coming From Your Engine A CAUTION: Steam from a n overheated engine can burn you badly, even if you ,justopen the hood. Stayaway from the engineif you see or hear steam coming from it. Just turn itoff and get everyone away from the vehicle until it cools down. Wait until there is no signof steam or coolant before you open the hood.
i o Stea 5 Coming From Your Engine ~iyou get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: 0 Climb a long hill on a hot day. Stop after high-speed driving. If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. 1.
When you decide it's safe to lift the hood, here's what you' I I see: I f the coolant inside the coolant recovery tank is boiling, don't do anything else until it cools down. I c. A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Fan The coolant level should be at least up to the ADD mark. If it isn't, you may have a leak i n the radiator hoses, heater hoses, radiator, water pump or somewhere elsein the cooling system.
1 h\ How to Add Coolant to the Coolant Recovery Tank CAUTION: If you haven’t found a problem yet, but the coolant level isn’t at the ADD mark, add a 50/50 mixture of clean brater (preferably distilled) and DEX-COOL@ engine coolant at the coolant recovery tank. (See “Engine Coolant” in the Index for more information.) Heater and radiatorhoses, and otherengine 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.
NOTICE: A CAUTION: In cold weather,water canfreeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture. You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and itwill burn if the engine parts arehot enough. Don’t spillcoolant on a hotengine. When the coolant in the coolant recovery tank is at the ADD r&ark,start your vehicle. If the overheat warning continues, there’s one more thing you can try.
CAC JON: Steam and scalding liquids from a hot cooling system can blow out and burnyou badly. They are under pressure, and if you turn the radiator pressure cap even a little they can come out at high speed. Neverturn the capwhen the cooling system,including the radiatorpressure cap, is hot. Wait for the cooling systemand radiator pressure cap to cool if you ever have to turn the pressure cap.
How to Add Coolant to the Radiator 2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap. I . You can remove the radiator pressure cap when the cooling system. including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
3. Fill the radiator with the proper DEX-COOL@ coolant mixture, up to the base of the filler neck. (See "Engine Coolant" in the Index for more information about the proper coolant mixture.) 5-18 4. Then fill the coolant recovery tank to the ADD mark. 5. Put the cap back on the coolant recovery tank, but leave the radiator pressure cap off.
.. .. 6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOL@ coolant mixture through the filler neck until the level reaches the base of the filler neck. 8. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap.
Engine Fan Noise If a Tire Goes Flat This 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 clutch is not engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases when the clutch 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 onyour hazard warning flashers. A CAUTION: I Changing a tire cancause an injury. Thev d c l e can slip off the jack androll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent thevehicle from moving: 1. Set the parkingbrake firmly. 2. Put the shiftlever in PARK (P). 3. l b r n off the engine. 4.
Removing the Spare Tireand Tools The jacking equipment you’ll need is stored along the driver’s side inner rear quarter panel. Your vehicle is also equipped with work gloves anda plastic ground mat to assist in the changing of a flat tire. To remove your jack cover, pull up on the latches on the cover. Remove the wheel blocks,jack and wheel wrench. 5-22 NOTICE: Never remove or restowa tire frodto a stowage position under the vehicle while the vehicle is supported bya jack.
Before you can lower the spare tire, you must remove of the rear the access hole cover on the passenger’s side bumper. Insert your index finger into the indentation near the lamp and pull to remove cover. the To remove the spare, insert the chisel end of the wheel wrench, on an angle, into the hole in the bumper. rear Be sure the chisel endof the wheel wrench connects into the hoist shaft.
Turn the wheel wrench to the left to lower the spare tire. Keep turning the wheel wrench until the spare tire can be pulled out from underthe vehicle. When the tire has been completely lowered, tilt the retainer at the end of the cable andpull it through the wheel opening. Pull the tireout from under the vehicle. NOTICE: To help avoid vehicle damage,do not drive the vehicle before thecable is properly stored. P the mare tire near the flat tire.
Removing the Flat Tire and Installing the Spare Tire Position the chisel end of your wheel wrench in the notch of the hub cap and pry off the hub cap. 1. Using the wheel wrench, loosen all the wheel nuts. Don’t removethem yet. 2. Turn the jack handle to the right to raise the jack lift head. 3. Fit the jack into the appropriate hole nearest the flat tire.
A 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 getunder a vehicle whenit is supported only by a jack. A CAUTION: A. Front Frame Hole B. Spring Hanger Hole 5-26 Raising your vehicle withthe jack improF,,,ly positioned can damagethe vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit thejack lift head into the proper location before raising the vehicle.
6. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. I 4. Raise the vehicle by turning the jack handle to the right. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit. 5 . Remove all the wheel nuts and take off the flat tire. I Rust or dirton the wheel, or on the parts to which it is fastened, can make thewheel nuts become looseafter a time. The wheel could come off and cause an accident.
/I\ CAUTION: Never use oilor grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident. 7. Place the spare on the wheel mounting surface. 8. Put the nuts on by hand. Make sure the cone-shaped end is toward the wheel. Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the wheel wrench and see your dealer as soon as possible. 5-28 9. Lower the vehicle by turning the jack handle to the left.

If You’re Stuck: In Sand, Mud, Ice or Snow NOTICE: What you don’t want to do when your vehicle is stuck is 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. A CAUTION: If you let your tires spinat high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fireor otherdamage.
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. Shift the transfer case into 4HI. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheelsas little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn’t get you out after a few tries, you may need to be towed out.
A CAUTION: The recovery hooks, when used,are undera 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 snappine back. I NOTICE: Never use the recovery hooks to tow the vehicle. Your vehicle could bedamaged and itwould not be covered by warranty.

Section 6 Service and Appearance Care Here you will find information aboutthe care of your vehicle. This section begins with service and fuel information, and then it shows how to check important fluidand 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 GM 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.
Fuel You can be injured and yourvehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. 0 Be sure you have sufficient knowledge, experience, the properreplacement parts and tools before you attempt anyvehicle maintenance task. 0 Be sure to use the proper nuts,bolts and other fasteners.“English” and “metric” fasteners canbe easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control label), it is designed to operate on fuels that meet California specifications. If such fuelsare not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected.
Fuels in Foreign Countries Filling Your Tank If you plan on driving in another country outside the United States or Canada,the proper fuel may be hard to find. Never use leaded gasoline any or other fuelnot recommended in the previoustext on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuelavailability, ask an auto club, or contact a major oil company that does business in the country whereyou’ll be driving.
- . . , . . , .. , . .. .. . .. To remove the cap, turn it slowly to the left (counterclockwise). The caphas a spring in it;if you let go of the cap toosoon, it will spring back to the right. Gasoline vapor is highly flammable. It burns violently, and that cancause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.
When you put the cap back on, turn it to the right (clockwise) untilyou hear a clicking sound. Make sure you fully install the cap.The diagnostic system can determineif the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp”in theIndex. NOTICE: If you need a new cap, be sure toget the right type. Your dealer canget onefor you. If you get the wrong type, it may not fitproperly.
Then go to the front of the vehicle and release the secondary hood release. Checking Things Underthe Hood Things that burncan get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant,brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine. - To open the hood, first pull the handle inside the vehicle on the lower driver’s side of the instrument panel.
When you lift the hood, you’ll see these items: C A. B. C. D. E. Battery Coolant Recovery Tank Engine Oil Dipstick Engine Oil Fill Transmission Dipstick E G. H. I. J.
Remove the hood prop from the slot in the hood and return the prop to its retainer. Then just pull the hood down firmly to close. It will latch when dropped from 10 to12 inches (25 to 30 cm) without pressing on the hood. 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 oil dipstick is a yellow ring.
Checking Engine Oil When to Add Engine Oil Pull out the dipstick and clean it with a paper towel or cloth, then pushit backin all theway. Remove it again, keeping the tip down, and check the level. If the oilis at or below the ADD line, then you’llneed of oil. Butyou must use the to add at least one quart right kind. This part explains what kind of oil touse. For crankcase capacity, see “Capacities and Specifications” in the Index. NOTICE: Don’t add too much oil.
What Kind of Eng 3il 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. I I RECOMMENDED SA€ VISCOSITY GRADE ENGINE OILS FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST SAL VISCOSITY GRADEOIL FOR THE EXPECTED TEMPERATURE RANGE.
As shown in the chart, SAE SW-30 is best for your vehicle. However, you can use SAE low-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-SO. 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.
Remote Oil Filter The access door for the remote oil filter is in the steering linkage shield assembly located under the radiator support. Twist the screw to unlock or lock the door. If you open the door, make sure it is securely closed when you are finished. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long.
A CAUTION: Automatic Transmission Fluid Operating theengine with the air cleaner off can cause you or others tobe burned. The air cleaner not only cleans the air,it stops flame if the engine backfires. If it isn’t there, and theengine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner off. A good time to check your automatic transmission fluid When to Check and Change level is when the engine oil is changed.
How to Check Because this operation can be a little difficult, you may choose to have this done at your GM dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false readingon the dipstick. NOTICE: Too much or toolittle fluid can damage your transmission. Too much can mean that someof the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire.
Checking Transmission Fluid Hot Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above50°F (10°C). If it's colder than 50°F (lO"C),drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. Then follow the hot check procedures. Checking Transmission Fluid Cold A cold check is made after the vehicle has been sitting for eight hours or more with the engine off and is used only as a reference.
2. Push it back in all the way, wait three seconds and then pull it back out again. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid only after checkingthe 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.
Rear Axle How to Check Lubricant When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check thelubricant and when to change it. See “Scheduled Maintenance Services”in the Index. If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use.
Four-wheel Drive How to Check Lubricant Transfer Case When to Check Lubricant Refer to the Maintenance Schedule todetermine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index. If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. Refer to the Maintenance Schedule to determine what kind of lubricant to use.
Front Axle When to Check and Change Lubricant When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole. Refer to the Maintenance Schedule to determinehow often to check the lubricant and when to change it. See ”Scheduled Maintenance Services” i n the Index. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole.
A 50/50 mixture of water and DEX-COOL@coolant will: 0 Give freezing protection down to -34°F (-37°C). Give boiling protection up to 265“F ( 129°C). 0 Protect against rust and corrosion. 0 Help keep the proper engine temperature. What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL@coolant which won’t damage aluminum parts. If you use this mixture, you don’t need to add anything else. Let the warning lights and gages work as they should.
NOTICE: Checking Coolant If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repaircost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crackthe engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system. NOTICE: If you use the propercoolant, you don’t have to add extra inhibitorsor additives which claim to improve the system.
- Radiator Pressure Cap A CAUTION: Turning the radiatorpressure cap when the engine and radiator arehot can allow steam and scalding liquids to blow out andburn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator.Never turn the radiatorpressure cap even a little when the engine and radiator arehot. -- -- Add coolant mixture at the recovery tank, but be careful not to spill it. A CAUTION: You can be burned if you spill coolant on hot engine parts.
Thermostat When to Check Power Steering Fluid Engine coolant temperature is controlled by a thermostat in the engine coolant system. Thethermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate aproblem. Have the system inspected and repaired.
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure toread 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. Open the cap labeled WASHER FLUID ONLY with the washer symbol on it. Add washer fluid until the tank is full.
Brakes Brake Fluid 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. Your brake master cylinder reservoir is here.
What to Add Checking Brake Fluid You can check the brake fluid without taking off the cap. When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 (GM Part No. 12377967). 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. A CAUTION: Just look at the brake fluid reservoir. The fluid level should be above MIN.
NOTICE: 0 Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someoneput 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.
Some driving conditionsor climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications. Brake linings should always be replaced as complete axle sets.
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. A 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. Contact your dealer to learn how to prepare your vehicle for longer storageperiods.

Inflation Poorly maintained and improperly used tires are dangerous. Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same dangeras overloaded tires. The resulting accident could cause serious injury.Check all tires frequently to maintain therecommended pressure. Tire pressure should be checked when your tires are cold.
NOTICE: (Continued) If your tireshave too much air (overinflation), you can get the following: 0 Unusualwear Badhandling Roughride Needless damage from road hazards. When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated.
+ Q I ! Rust or dirton a wheel, or on the parts to which it is fastened, can make 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 dirtfrom 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 touse a scraper or wire brush later, if you need to, to get all the rustor dirt off. (See “Changing a Flat Tire” in the Index.
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. You need a new tire if any of the following statements are true: 0 You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.
I Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial andbias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes mayalso cause damage toyour vehicle. Be sure to use the same size and type tireson all wheels. If you use bias-ply tires on your vehicle, the wheel rim flanges could developcracks after many miles of driving. A tire and/orwheel could fail suddenly, causing a crash.
-- A, B, C Treadwear Temperature 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.
Wheel Alignment and TireBalance Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the The wheels on your vehicle were aligned and balanced same way as the one it replaces. carefully at the factory to give you the longest tire life If you need to replace anyof your wheels, wheel and best overall performance. bolts or wheel nuts, replace them only with new GM Scheduled wheel alignment and wheel balancing are original equipment parts.
NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlampaim, bumper height, vehicle ground clearance and tire clearance to thebody and chassis. See “Changing a Flat Tire” in the Index for more information. Used Replacement Wheels I Putting a used wheel on your vehicle is dangerous. You can’t know how it’sbeen used or how far it’s beendriven. It could fail suddenly and cause an accident.
Appearance Care 0 Acetone Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get themon a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a containerto clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaningthe inside.
Cleaning the Insideof Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfxes with a clean, dampcloth. Your dealer has two cleaners, Multi-Purpose Interior Cleaner and Capture Non-Solvent Dry Spot and Soil Remover for cleaning fabric and carpet. They will clean normal spots and stains very well. You can get GM-approved cleaning products from your dealer. (See “Appearance Care and Materials” in the Index.
Special Fabric Cleaning Problems Fabric Protection Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: Your vehicle has upholstery and carpet that has been treated with Scotchgard” Fabric Protector, a 3M product. It protects fabrics by repelling oil and water, which are the carriers of most stains. Even with this protection, you still need to clean your upholstery and carpet often to keep it looking new. 1.
Cleaning Leather Cleaning Interior Plastic Components Use a soft cloth with lukewarm water and a mild soap or saddle soapand wipe dry with a soft cloth. Then,let the leather dry naturally. Do not use heat to dry. Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish. 0 For stubborn stains, use a leather cleaner. See your dealer for this product.
Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust filmson interior glass. Don’t use abrasive cleanerson glass, because they may cause scratches. Avoid placing decals onthe inside rear window, since they may have to be scrapedoff later. If abrasive cleaners areused on the inside of the rear window, an electric defogger elementmay be damaged.
Cleaning the Outside of Your Vehicle Cleaning Exterior LampsLenses The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Use lukewarm or cold water, a soft cloth and a liquid hand, dish or car washing (mild detergent) soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.’’ Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years.
Finish Damage Chemical Paint Spotting Any stone chips, fracturesor deepscratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop intoa major repair expense. Some weather and atmospheric conditionscan create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on yourvehicle. This damage can take two forms:blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface.

I Introduction IMPORTANT: KEEP ENGINE OIL AT THE PROPER LEVEL AND CHANGE AS RECOMMENDED I Protection Plan Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle i n good working condition, but also helps the environment. All recornmended maintenance procedures are inymrtant. Improper vehicle maintenance can even affect the quality o f the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions fro111 your vehicle.
A A CAUTION: Performing maintenance work ona vehicle can be dangerous. In trying to do some .jobs, you can be seriously injured.Do your own maintenance work only if you have the required know-how and the propertools and equipment for the job. If you have any doubt, havea qualified technician do thework. If you are skilled enough to do some work on your vehicle, you will probably want to get the service information. See “Service and Owner Publications“ in the Index.
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 a Or you may drive distances only a few times week. 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 orin many other ways.
Maintenance Schedule I Short Trip/City Definition I Follow the Short TripKity Maintenance Schedule if any one of these conditions is true for your vehicle: Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). You operate your vehicle in dusty areas 6r off-road frequently. 0 You frequently tow a trailer or use a carrier on top of your vehicle.
