A CAUTION: A - -

Make sure the tire and carrier are secure. Driving with the tire or carrier unlatched could injure pedestrians or damage the vehicle.

Compact Spare Tire (If Equipped) Although the compact spare tire was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 Wa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.

NOTICE:

When the compact spare is installed, don’t take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.

Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wl~eel with other wheels or tires. They won’t fit. Keep your spare tire and its wheel together.

NOTICE:

Tire chains won’t fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare.

If You’re Stuck: In Sand, Mud, Ice or Snow 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.

If you let your tires spin at high speed, they can explode, and you or others could be in,jured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 k m h ) as shown on the speedometer.

5-32

NOTICE:

Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.

For information about using tire chains on your vehicle, see "Tire Chains" in the Index. Rocking Your Vehicle To Get It Out First, turn your- steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn't get you out after a few tries, you may need to be towed out. Or, you can use your recovery hooks if your vehicle has them. If you do need to be towed out, see "Towing Your Vehicle'' in the Index.

Using the Recovery Hooks

Your vehicle is equipped with recovery hooks. The recovery hooks are provided at the front of your vehicle. You may need to use them if you're stuck off-road and need to be pulled to someplace where you can continue driving.

5-33

The recovery hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back.

I NOTICE:

tow the vehicle. Never use the recovery hooks to Your vehicle could be damaged and it would not be covered by warranty.

Service Your retailer knows your vehicle best and wants you to be happy with it. We hope you‘ll go to your retailer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks: ACDelw,: Genuine

Doing Your Own Service Work 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. Your vehicle has an air bag system. Before attempting t.o do your own service work, see “Servicing Your Air Bag-Equipped Vehicle” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

Parts

6-2

You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. 0 Be sure you have sufficient knowledge,

experience, the proper replacement parts and tools before you attempt any vehicle maintenance task.

0 Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.

Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your retailer before adding equipment to the outside of your vehicle. Fuel Use regular unleaded gasoline rated at 87 octane or higher. At a minimum, it should meet specifications ASTM D48 14 in the United States and CGSB 3.5-M93 in Canada. Improved gasoline specifications have been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and emission control system protection compared to other gasolines.

Be sure the posted octane is at least 87. If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine. If you’re using fuel rated at 87 octane or higher and you hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. 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 fuels are 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.

The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized GM retailer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty. Some gasolines that are not reformulated for low emissions contain an octane-enhancing additive called tnethylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel contains MMT. General Motors does not recommend the use of such gasolines. If fuels containing MMT are used, spark plug life may be reduced and your emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized GM retailer for service.

6-4

To provide cleaner air, all gasolines in the United States are now required to contain additives that w i l l help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier.

NOTICE:

Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty.

Fuels in Foreign Countries 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 or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your wa1-ranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write LIS at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

Filling Your Tank

Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.

The fuel cap is behind a hinged door on the driver’s side of your vehicle.

6-6

While refueling, hang the cap by the tether from the hook on the filler door. To remove the cap, turn it slowly to the left (counterclockwise). The cap has a spring in it; if you let L go of the cap too soon, it will spring back to the right.

If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if‘ your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the wav.

When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you filly install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index.

NOTICE:

If you need a new cap, be sure to get the right type. Your retailer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and your fuel tank and emissions system may be damaged. See “Malfunction Indicator Lamp” in the Index.

Be careful not to spill gasoline. Clean gasoline from painted surfaces a s soon as possible. See “Cleaning the Outside of Your Vehicle” i n the Index.

Filling a Portable Fuel Container

Checking Things Under the Hood

Things that burn can 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.

Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others:

Dispense gasoline only into approved containers. Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground. Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete. Don’t smoke while pumping gasoline.

6-8

To open the hood, first pull the handle inside the vehicle on the lower driver’s side of the instrument panel.

Then go to the front of the vehicle and release the secondary hood release.

Lift the hood, release the hood prop from its retainer and put the hood prop into the slot in the hood. You may have a lamp that comes on when you lift the hood.

When you lift the hood, you’ll see these items:

A. Battery B. Coolant Recovery Tdnk C. Engine Oil Dipstick D. Engine Oil Fill

E. Transmission Dipstick F. Power Steering Reservoir G. Brake Master Cylinder H. Air Cleaner

I. Engine Compartment

Checking Engine Oil Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.

Before closing the hood, be sure all the filler caps are on properly. Then lift the hood to relieve pressure on the hood prop. 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 to 12 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. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level.

When to Add Engine Oil If the oil is at or below the ADD line, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

What Kind of Engine Oil to Use Oils recommended for your vehicle can be identified by looking for the “Starburst“ symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this Starburst symbol.

NOTICE:

Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged.

Be sure to fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

If you change your own oil, be sure you use oil that has the Starburst symbol on the front of the oil container.

FOR rn L

If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for gasoline engines. You should also use the proper viscosity oil for your vehicle, as shown in the following chart:

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED

As shown in the chart, SAE 5W-30 is best for your vehicle. However. you can use SAE 1OW-30 if it's going to be 0°F (- 1 8°C) or above. These numbers on an o i l container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50.

NOTICE:

Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines "Starburst" symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.

GM Goodwrench@ oil meets all the requirements for your vehicle. If you are in an area where the temperature falls below -20°F (-29"C), consider using either an SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures.

Engine Oil Additives Don’t add anything to your oil. Your retailer is ready to advise if you think something should be added. When to Change Engine Oil If any one of these is true for you, use the short triplcity maintenance schedule:

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 or off-road frequently. You frequently tow a trailer or use a carrier on top of your vehicle. The vehicle is used for delivery service, police. taxi or other commercial application.

Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months -- whichever occurs first. If none of them is true, use the long triplhighway maintenance schedule. Change the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower.

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. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your retailer, a service station or a local recycling center for help.

Air Cleaner

To remove the air cleaner, remove the wing nuts that hold the cover on. Remove the cover and lift out the air filter. Insert a new air filter, then replace the air cleaner cover Tighten the wing nuts to hold the cover in place.

6-15

Automatic Transmission Fluid When to Check and Change A good time to check your automatic transmission fluid level is when the engine oil is changed. Change both the fluid and filter every 15,000 miles (25 000 k m ) if the vehicle is mainly driven under one or more of these conditions:

In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. In hilly or mountainous terrain.

0 When doing frequent trailer towing. 0 Uses such as found in taxi, police or delivery service. If you do not use your vehicle under any of these conditions, change the fluid and filter every 50,000 miles (83 000 km). See ”Scheduled Maintenance Services” in the Index.

Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.

I NOTICE:

If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.

How to Check Because this operation can be a little difficult, you may choose to have this done at your GM retail facility Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

NOTICE:

Too much or too little fluid can damage your transnlission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.

Wait at least 30 minutes before checking the transmission fluid level if you have been driving: 0 When outside temperatures are above 90°F (32°C). 0 At high speed for quite a while.

In heavy traffic -- especially in hot weather. While pulling a trailer.

To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). See "Checking Transmission Fluid Hot" i n the Index.

Checking Transmission Fluid Hot Get the vehicle warmed up by driving about 15 miles (24 k m ) when outside temperatures are above 50°F (10°C). If it's colder than 50°F ( I O O 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.

Then, without shutting off the engine, follow these steps:

I . Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel.

2. Push it back in all the way, wait three seconds and

then pull it back out again.

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. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more. If it's colder than 50°F (lO"C), you may have to idle the engine longer. Should the fluid level be low during a cold check, you must perform a hot check before adding fluid. This will give you a more accurate reading of the fluid level.

Checking the Fluid Hot or Cold

Park your vehicle on a level place. Keep the engine running. With the parking brake applied, place the shift lever in PARK (P). With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P).

0 Let the engine run at idle for three minutes or more.

6-18

How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants’’ in the Index. Add fluid only after checking the transmission fluid while it is hot. (A cold check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overJiZ1.

3. Check both sides of the dipstick, and read the lower

level. The fluid level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check.

4. If the fluid level is in the acceptable range, push the

dipstick back in all the way; then flip the handle down to lock the dipstick in place.

NOTICE:

We recommend you use only fluid labeled DEXR0N’-III, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRON-ZLI is not covered by your new vehicle warranty.

0 After adding fluid, recheck the fluid level as

described under “How to Check.” When the correct fluid level is obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

All-Wheel Drive Transfer Case When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index.

How to Check Lubricant

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. See “Recommended Fluids and Lubricants” in the Index. Engine Coolant The cooling s stem in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL@ extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. A 50/50 mixture of water and DEX-COOL@ coolant will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 265°F (129°C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights and gages work as they should.

NOTICE:

When adding coolant, it is important that you use only DEX-COOL@ (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOL@ is not covered by your new vehicle warranty.

What to Use Use a mixture of one-half OIPLUZ rt:afer (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.

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle's coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn't get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of' clean water and DEX-COOL@ coolant.

Checking Coolant

When your engine is cold, the coolant level should be at ADD, or a little higher. When your engine is warm, the level should be up to FULL HOT, or a little higher.

NOTICE:

If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts.

If you have to add coolant more than four times a year, have your retailer check your cooling system.

I NOTICE:

If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

6-24

Adding Coolant If you need more coolant, add the proper DEX-COOL@ coolant mixture at the coolant recovery tank.

A CAUTION:

Thrning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap -- even a little -- when the engine and radiator are hot.

Add coolant mixture at the recovery tank, but be careful not to spill it.

I A CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

6-25

Radiator Pressure Cap

Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. Power Steering Fluid

NOTICE:

Your radiator cap is a 15 psi (105 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck.

6-26

When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How To Check Power Steering Fluid When the engine compartment is cool, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be between the ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the proper range.

What to Use To determine what kind of fluid to use, see ”Recommended Fluids and Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.

Adding Washer Fluid

Open the cap labeled WASHER FLUID ONLY with the washer symbol o n it. Add washer fluid until the tank is full.

6-28

NOTICE:

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only three-quarters full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. Don’t use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint.

Brakes Brake Fluid

Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level i n the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during norlnal brake lining weal-. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out

of the brake system. If it is, you should have y o ~ ~ r brake system tlxed, since a leak nleans that sooner or later your brakes won't work well, or won't work at all. So. i t isn't a good idea to "top oft'' 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.

If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.

Refer to the Maintenance Schedule to determine when to check your brake fluid. See "Periodic Maintenance Inspections" in the Index.

6-29

What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 1 I @ (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.

With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.

Checking Brake Fluid

Just look at the brake fluid reservoir. The fluid level should be above MIN. If it isn't, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark or the top of the window on the side of the reservoir.

6-30

NOTICE:

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 someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

The brake wear warning sound means that soon your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.

1 NOTICE:

Continuing to drive with worn-out brake pads could result in costly brake repair.

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your bra cz k es. 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. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.’’

.e Pedal Travel

See your retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear.

Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new approved GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change -- for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Every new vehicle has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label.

6-32

Vehicle Storage 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.

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 retailer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see ”Theft-Deterrent Feature” in the Index. Bulb Replacement Before you replace any bulbs, be sure that all the lamps are off and the engine isn’t running. See ”Replacement Bulbs” in the index for the proper type of bulb to use.

The backglass wiper blade will not lock in a vertical position like the windshield wiper blade, so care should be used when pulling it away from the vehicle. Tires Your new vehicle comes with high-quality tires made by a leading tire manufxturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details.

A c;

TTmT .ON:

Poorly maintained and improperly u5 - __ 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 danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more likely to be cut, punctured or broken by a sudden

impact -- such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

6-37

Inflation -- Tire Pressure The CertificatiodTire label, which is on the driver’s door edge, above the door latch, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile ( I .6 km).

NOTICE:

Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following:

Too much flexing

0 Too much heat

Tire overloading

0 Bad wear 0 Bad handling 0 Bad fuel economy.

NOTICE: (Continued)

6-38

I NOTICE: (Continued)

If your tires have too much air (overinflation), you can get the following: 0 Unusual wear Bad handling

0 Rough ride 0 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. If you have a compact spare tire, it should be at 60 psi (420 kPa).

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. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.

Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to I3 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information. The purpose of regular rotation is to achieve more lrniform wear for all tires on the vehicle. The first rotation is the most important. See ”Scheduled Maintenance Services” in the Index for scheduled rotation intervals.

When rotating your tires, always use the correct rotation pattern shown here. If your vehicle has a compact spare tire, don’t include it in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the CertificatiodTire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque’‘ in the Index.

Rust or dirt on 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 dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. (See “Changing a Flat Tire” in the Index.)

When It’s Time for New Tires I One way to tell when it’s

0 The tire has a bump, bulge or split.

time .for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 m m ) or less of tread remaining.

You need a new tire if any of-. the following statements are true:

You can see the indicators at three or more places around the tire.

a 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.

The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.

Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same ?’PC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things durinz normal service on your vehicle. If your tires have an all-season tread design. the TPC number will be followed by an “MS” (for mud and snow). If you ever replace y o ~ ~ r tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.

Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to Federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.

CAUTION:

Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare (if you have one). It was developed for use on your vehicle.

A CAUTION:

If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle.

Temperature -- A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Treadwear 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. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction -- A, B, C The traction grades, from highest to lowest, are A, B, and C , and they represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.

Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your retailer if any of these conditions exist. Your retailer will know the kind of wheel you need.

Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your GM model.

l Using the wrong replacement wheels, wheel

bolts or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement.

NOTICE:

The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire clearance to the body and chassis.

See “Changing a Flat Tire” in the Index for more information.

Used Replacement Wheels

/1\ M

CP ““‘3N:

Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or hotv far it’s been driven. It could fail suddenly and cause an accident. If you have to replace a wheel, use a new GM original equipment wheel.

Tire Chains

NOTICE:

______

Don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels.

Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside.

Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your retailer has two cleaners, Multi-Purpose Interior Cleaner and Capture Non-Solvent Dry Spot and Soil Remover. They will clean normal spots and stains very well. You can get GM-approved cleaning products from your retailer. (See "Appearance Care a11d Materials" in the Index.) Here are some cleaning tips:

Always read the instructions on the cleaner label. Clean up stains as soon as you can -- before they set. Carefully scrape off any excess stain. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. If a ring forms after spot cleaning, clean the entire area immediately or it will set.

may have to do it more than once.

0 Things like tar, asphalt and shoe polish will stain

if you don’t get them off quickly. Use a clean cloth and a vinylheather cleaner. See your retailer for this product.

Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry. 0 For stubborn stains. use a leather cleaner. See your

retailer for this product. N c w r use oils, varnishes? solvent-based or abrasive cleaners. furniture polish or shoe polish on leather. Soiled or stained leather should be cleaned immediately. If dirt is allowed to work into the finish. it can 11arm the leather.

Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections i n the windshield and even make it difficult to see through the windshield under certain conditions. Cleaning Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Comnlercial cleaners may affect the surface finish.

Care of Safety Belts Keep belts clean and dry.

I A CAUTION:

dye safety belts. If you do, it

Do not bleach!! may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner w i l l remove normal tobacco smoke and dust films on interior glass. Don't use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

Cleaning the Outside of the Windshield, Backglass and Wiper Blades If the windshield is not clear after using the windshield washer. or if the wiper blade chatters when running, wax, sap or other material may be on the blade or Windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon Ami@ Powder (non-scratching glass cleaning powder), GM Part No. 10500 I 1. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary: replace blades that look worn. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent

6-48

application may be required. (See “Recommended Fluids and Lubricants” in the Index.) Cleaning the Outside of Your Vehicle The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. 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. Don’t wash your vehicle i n the direct rays of the sun. Don‘t use strong soaps or chemical detergents. Use liquid hand. dish or car washing (mild detergent) soaps. You can get GM-approved cleaning products from your retailer. (See “Appearance Care and Materials?’ in the Index.) Don’t use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle.

Cleaning Exterior Lamps/Lenses 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 “Wdshing Your Vehicle.” Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your retailer. (See ”Appearance Care and Materials” in the Index.) Your vehicle has a ”basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish.

I NOTICE:

Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may dull the finish or leave swirl marks.

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. You can help to keep the paint finish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is a l l that is usually needed. However, ~ O L I chrome 01- stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for a l l bright metal parts.

Cleaning Aluminum Wheels Keep your wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners or abrasive cleaning brushes on them because you could damage the surface. Don’t take your vehicle through an automatic car wash that has silicon carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.

Cleaning Tires To clean your tires, use a stiff brush with a tire cleaner.

NOTICE:

When applying a tire dressing always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle. Petroleum-based products may damage the paint finish.

Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to the parts repaired or replaced to restore corrosion protection.

6-50

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can f i l l upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 k m ) of purchase. whichever occurs first.

Fi nish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your retailer or other service outlets. Larger areas of finish damage can be col-rect.ed in your retailer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your retailer or an underbody car washing system can do this for you.

I NOTICE:

~~~~~~

Don’t add anything electrical to your vehicle unless you check with your retailer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should.

Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle. see “Servicing Your Air Bag-Equipped Vehicle” in the Index.

Headlamps The headlamp wiring is protected by an internal circuit breaker. An electrical overload will cause the lamps to go o n and off. or in some cases to remain off. If this happens, have your headlamp wiring checked right away. Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, be sure to get it fixed. Power Windows and Other Power Options Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit m t i l the problem is fixed or goes away.
