Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-23.


Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See fati A: Scheduled Maintenance Services on page 6-4 for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (don’t overfill), engine oil, drive belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly. If you’re trailering, it’s a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.

Service 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. We hope you’ll want to keep your GM vehicle all GM Genuine GM parts have one of these marks:


Doing Your Own Service Work If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see Service Publications Ordering information on page 7- 10. Your vehicle has an air bag system. Before attempting to do your own service work, see Servicing Your Air Bag-Equipped Vehicle on page 1-59.


5-3


Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle.


You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See Pat? E: Maintenance Record on page 6-23.


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.


Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. 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.


5-4


Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle. Gasoline Octane Use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher-octane fuel is necessary. If you are using 87 octane or higher-octane fuel and hear heavy knocking, your engine needs service.


Gasoline Specifications


It is recommended that gasoline meet specifications which were developed by the American Automobile Manufacturers Association and endorsed by the Canadian Vehicle Manufacturers Association for better vehicle performance and engine protection. Gasoline meeting these specifications could provide improved driveability and emission control system performance compared to other gasoline.


In Canada, look for the “Auto Makers’ Choice” label on the pump.


Canada Only


5-5


California Fuel If your vehicle is certified to meet California Emission Standards (see the underhood emission control label), it is designed to operate on fuels that meet California specifications. If this fuel is 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 may turn on (see Malfunction lndicator Lamp on page 3-31 ) and your vehicle may fail a smog-check test. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty. Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel.


Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the specifications described earlier.


Notice: Your vehicle was not designed for fuel that contains methanol. Don’t use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage wouldn’t be covered under your warranty. Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service.

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 warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. Filling Your Tank

To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap has a spring in it; if you let go of the cap too soon, it will spring back to the right.


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


Be careful not to spill fuel. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle on page 5-75.


While refueling, hang the tethered cap inside the fuel door.


5-8


When you put the fuel cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully 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 lndicator Lamp on page 3-3 1. Notice: If you need a new fuel cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See “Malfunction lndicator Lamp” in the Index.


Fi”’ng a Portable Fuel Co


‘ainer


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:


0 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. 0 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.

4. Release the hood prop rod from its retainer and put the hood prop into the slot marked PROP ROD.


2, Then go to the front of the vehicle and lift the secondary hood release handle before lifting the hood.


3. Lift the hood.


Before closing the hood, be sure all the filler caps are on properly. Lift the hood to relieve pressure on the hood prop. Then let the hood drop from about 8 to 12 inches (20 to 30 cm) above the vehicle to latch fully. Check to make sure the hood is closed and repeat the procedure if necessary.

Engine Oil


Checking Engine Oil It's a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.


The engine oil dipstick is located in the front of the engine compartment. The top of the dipstick is a round, yellow loop. See Engine Compartment Overview on page 5- 12 for more information on location.


CHECK


OIL


If the CHECK OIL light appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see Check Oil Level Light on page 3-35.


You should check your engine oil level regularly; this is an added reminder.


Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. Fuii iile ciipsiick a d ciearl ii w i t ] a paper iowei or ciuiil, then push it back in all the way. Remove it again, keeping the tip down and check the level.


5-1 3


Notice: Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged.


For engine oil fill cap location see Engine Compartment Overview on page 5- 12.

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


If you choose to perform the engine oil change service yourself, be sure the oil you use has the starburst symbol on the front of the oil container. 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 viscosity chart.

As in the chart shown previously, SAE 5W-30 is the only viscosity grade recommended for your vehicle. You should look for and use only oils which have the API Starburst symbol and which are also identified as SAE 5W-30. If you cannot find such SAE 5W-30 oils, you can use an SAE IOW-30 oil which has the API Starburst symbol, if it's going to be 0°F (-18°C) or above. Do not use other viscosity grade oils, such as SAE IOW-40 or SAE 20W-50 under any conditions. 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 of extreme cold, where the temperature falls below -20°F (-29"C), recommended that you use 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. The recommended oils with the starburst symbol are all you will need for good performance and engine protection.

When to Change Engine Oil If any one of these is true for you, use the short tripkity maintenance schedule:


Most trips are less than 5 miles (8 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 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 trip/highway maintenance schedule. Change oil and filter every 7,500 miles (1 2 500 km) or 12 months - whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower.


Engine Air Cleaner/Filter


What to Do with Used Oil 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 dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never 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 dealer, a service station or a local recycling center for help.


The engine air cleanedfilter is located in the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location.


5-1 7


To check or replace the engine air cleanedfilter, do the following: 1. Remove the screws that hold the cover on. 2. Lift off the cover. 3. Check or replace the engine air cleaner/filter. See Normal Maintenance Replacement Parts on page 5-88 for replacement part numbers.


4. Put the cover back on tightly. See Using Your Maintenance Schedule on page 6-4 for replacement intervals.


Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner/filter off.


Notice: If the air cleaner/filter 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/filter in place when you’re driving. 5-1 8


Automatic Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealership service department and have it repaired as soon as possible. You may also have your fluid level checked by your dealer or service center when you have your oil changed. Change both the fluid and filter every 50,000 miles (83 000 km) 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. When doing frequent trailer towing. Uses such as found in taxi, police or delivery service.


If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing. Notice: We recommend you use only fluid labeled DEXRON@-III, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON@-Ill is not covered by your new vehicle warranty.


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 -- at 30,000 miles coolant will require change sooner (50,000 km) or 24 months, whichewer occurs first, Damage caused by the use of coolant other than DEX-COOL@ is not covered by your new vehicle warranty.


Engine Coolant The cooling system in your vehicle is filled with DEX-COOL@ engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL@ extended life coolant. 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 on page 5-23. A 50/50 mixture of clean, drinkable water and DEX-COOL@ coolant will:


Give freezing protection down to -34" F (-37°C).


0 Give boiling protection up to 265°F (129°C) 0 Protect against rust and corrosion. 0 Help keep the proper engine temperature. 0 Let the warning lights and gages work as they


should.


5-1 9


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 dealer check your cooling system. 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.


What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL@ coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add r r t h i n g else.


Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong too hot but you mixture, your engine could get wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50150 mixture of clean, drinkable water and DEX-COOL@ coolant.


5-20


Checking Coolant


The engine coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location.


5-21


m


If the low coolant light comes on and stays on, it means you’re low on engine coolant.


See Low Coolant Warning Light on page 3-30 for more information. Adding Coolant If you need more coolant, add the proper QEX-COOL@ coolant mixture at the surge tank, but only when the engine is cool. If the surge tank is empty, a special fill procedure is necessary. See Engine Overheating on page 5-23 and Cooling System on page 5-25.


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


When replacing the pressure cap, make sure it is hand-tight. Coolant Surge Tank Pressure Cap Nofice: Your pressure 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.


5-22


Engine Overheating You will find a coolant temperature gage and a low coolant level warning light on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 3-30 and Low Coolant Warning Light on page 3-30. If Steam Is Coming From Your Engine


Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.


Nofice: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty.


5-23


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. If there’s still no sign of steam, idle the engine for three minutes while you’re parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood but to get service help right away.


If No Steam Is Coming From Your Engine An overheat warning, along with a low coolant light, can indicate a serious problem. See Low Coolant Warning Light on page 3-30. If you get an engine overheat warning with no low coolant light, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:


Climb a long hill on a hot day. Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer.


If you get the overheat warning with no sign of steam, try this for a minute or so: 1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle.


2. Turn on your heater to full hot at the highest fan


speed and open the window as necessary.


5-24


Cooling System


When you decide it’s safe to lift the hood, here’s what you’ll see:


An electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.


If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. The vehicle should be parked on a level surface.


A. Electric Engine Cooling Fans B. Coolant Surge Tank with Pressure Cap


5-25


Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.


The coolant level should be at or above the FULL COLD mark. If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.


If there seems to be no leak, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service.


5-26


Notice: Engine damage from running your engine without coolant isn’t covered by your warranty. Nofice; 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.


How to Add Coolant to the Coolant Surge Tank Nofice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If you haven’t found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level isn’t at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL@ coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See Engine Coolant on page 5-19 for more information.


5-27


If no coolant is visible in the surge tank, add coolant as follows:


Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap - even a little - they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.

By this time, the coolant level inside the coolant sIJrge tank may be lower If the level is lower than the FULL COLD mark, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark.


5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated.

Power Steering Fluid


How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. What to Use To determine what kind of fluid to use, see Part D: Recommended Fluids and Lubricants on page 6-22. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.


When to Check Power Steering Fluid See Engine Compartment Overview on page 5-12 for reservoir location. 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.

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


The windshield washer fluid reservoir is located on the driver’s side of the engine compartment. See Engine Compartment Overview on page 5- 12 for reservoir location.


Open the cap with the washer symbol on it. Add washer fluid until the tank is full. Notice:


When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. 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.


5-33


Brakes Brake Fluid


DOT 3


Your brake master cylinder reservoir is on the driver’s side of the engine compartment. It is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 5- 12. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal


5-34


brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off1 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 -.-._e 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.

With the wrong kind of l.-.d in you. _.-.[e system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the propel‘ brake fluid.


When your brake fluid falls to a low level, your brake warning light will come on. See Brake System Warning Light on page 3-28. What to Add When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See Part D: Recommended Fluids and Lubricants on page 6-22. Always clean the brake fluid reservoir cap’afid the area around the cap before removing it. This will help keep dirt from entering the reservoir.


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 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.


5-35


Brake Wear Your vehicle has front disc brakes and rear drum 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 ‘ake wear warning sound eans 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.


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 brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to GM torque specifications. Your rear drum brakes don’t have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected immediately. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brake pads replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. See Brake System Inspection on page 6-27.


5-36


Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a moderate brake stop, your disc brakes adjust for wear. If you rarely make a moderate or heavier stop, then your brakes might not adjust correctly. If you drive in that way, then - very carefully - make a few moderate brake stops about every 1,000 miles (1 600 km), so your brakes will adjust properly. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by pumping the brake pedal repeatedly while the engine is running with the shift lever in PARK (P).


Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system - for example, when your brake linings wear down and you need new ones put in - be sure you get new approved 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.


5-37


Battery Your new vehicle comes with a maintenance free ACDelco@ battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco@ battery. See Engine Compartment Overview on page 5- 12 for battery location. Warning: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.


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.


Batt -~ .es 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 storage periods. Also, for your audio system, see Theft-Deterrent Feature (Non-RDS Radios) on page 3-61 or Theft-Deterrent Feature (RDS Radios) on page 3-61.


5-38


Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to follow the steps below to do it safely.


Lb C,AUTION:


Batteries can hurt you. They can be dangerous because:


0 They contain acid that can burn you. They contain gas that can explode or ignite,


0 They contain enough electricity to


burn you.


If you don’t follow these steps exactly, some or all of these things can hurt you.


Nofice: Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty. Trying to start your vehicle by pushing or pulling it won’t work, and it could damage your vehicle. 1. Check the other vehicle. It must have a 12-volt


battery with a negative ground system.


Notice: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transaxle in PARK (P) or a manual transaxle in iW3JiXAL beiore setting tne parking brake.


5-39


Notice: If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty. 3. Turn off the ignition on both vehicles. Unplug


unnecessary accessories plugged into the cigarette lighter or in the accessory power outlet. Turn off the radio and all lamps that aren’t needed. This will avoid sparks and help save both batteries. And it could save your radio!


4. Open the hoods and locate the batteries. Find the positive (+) and negative (-) terminal locations on each vehicle. See Engine Compartment Overview on page 5-72 for more information on location.


An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.


5-40


the ACDelco@ battery


Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don’t need to add water to installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.


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 things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (-) will go to a heavy, unpainted metal engine part or to a remote negative (-) terminal if the vehicle with the dead battery has one. Don’t connect positive (+) to negative (-) or you’ll get a short that would damage the battery and maybe other parts, too. And don’t connect the negative (-) cable to the negative (-) terminal on the dead battery because this can cause sparks.


I Fans or other moving engine parts can injure I you baaiy. Keep your nancis away from moving


parts once the engine is running.


6. Connect the red positive (+) cable to the positive (+)


‘terminal of the dead battery. Use a remote positive (+) terminal if the vehicle has one.


5-4 1


7. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.


8. Now connect the black


negative (-) cable to the negative (-) terminal of the good battery. Use a remote negative I-) terminal if the vehicle has one.


Don’t let the other end touch anything until the next step. The other end of the negative (-) cable doesn’t go to the dead battery. It goes to a heavy, unpainted metal engine part or to a remote negative (-) terminal on the vehicle with the dead battery.


5-42


9. Connect the other end of the negative (-) cable at


least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less. If the THEFT SYSTEM light flashes, wait until the light stops flashing.


10.


11.


Now start the vehicle with the good battery and run the engine for a while. Try to start the vehicle that had the dead battery. If it won’t start after a few tries, it probably needs service.


Notice: Damage to your vehicle may result from electrical shorting if jumper cables are removed incorrectly. To prevent electrical shorting, take care that the cables don’t touch each other or any other metal. The repairs wouldn’t be covered by your warranty.


5-43


To disconnect the jumper cables from both vehicles, do the following: 1. Disconnect the black negative (-) cable from the


vehicle that had the dead battery.


2. Disconnect the black negative (-) cable from the


vehicle with the good battery.


3. Disconnect the red positive (+) cable from the


vehicle with the good battery.


4. Disconnect the red positive (+) cable from the


other vehicle.

Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your Chevrolet Warranty booklet for details.


Poorly maintained and improperl- s e d 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.


CAUTION:


(Continued)


Underihflated 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.


5-52


Inflation - Tire Pressure The Tire-Loading Information label, which is located on the driver’s side rear passenger door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Notice: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: 0 Too much flexing 0 Too much heat 0 Tire overloading 0 Bad wear 0 Bad handling e Bad fuel economy


If your tires have too much air (overinflation), you can get the following: 0 Unusual wear 0 Bad handling 0 Rough ride 0 Needless damage from road hazards When to Check Check your tires once a month or more. Don’t forget your 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.


5-53


Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (IO 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-55 and Wheel Replacement on page 5-58 for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Part A: Scheduled Maintenance Services,” in Section 6, for scheduled rotation intervals.


Don’t include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 5-87.


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 rotating your tires, always use the correct rotation pattern shown here.


5-54


When It Is Time for New Tires


One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.


indicators at three or more places


You need a new tire if any of the following statements are true: 0 You can see the 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. The tire has a bump, bulge or split.


0 The tire has a puncture, cut or other damage that


can’t be repaired well because of the size or location of the damage.


5-55


Buying New Tires


To find out what kind and size of tires you need, look at the Tire-Loading Information 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 TPC 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 during 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 your 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.


5-56


Mixin, Lires 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, though. It was developed for use on your vehicle.


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


Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A 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.


times as well on the government course as


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 5
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 - AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cnrnering, hyrjronlanin9, or peak traction characteristics.


5-57


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 6 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.


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 dealer if any of these conditions exist. Your dealer will know the kind of wheel you need.


5-58


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 vehicle.


Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-61 for more information. Used Replacement Wheels


Using _.._ Nrong replacement wl.-As, 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.


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


5-59


Tire Chains


Notice: Use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires. Install them on as possible the front tires and tighten them as tightly with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.


If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout”, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop - well off the road if possible. If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.

Changing a Flat Tire


If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.


Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving:


1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine.


To be even more certain the vehicle won’t move, you can put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end.


The following steps will tell you how to use the jack and change a tire.


5-61


Turn the wing nut counterclockwise and remove it. Then lift off the adapter and remove the compact spare tire. See Compact Spare Tire on page 5-71 for more information about the compact spare tire.


4. Remove the jack and wrench from the trunk. Your


vehicle's jack and wrench are stored in a foam tray.


2. Lift and remove the cover.

from the wheel bolts, mounting surfaces and spare wheel.


5. Raise the vehicle by turning the wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit.


6. Remove all of the wheel nuts. 7. Then take off the flat tire.


Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.

11. Tighten the wheel nuts


firmly in a crisscross sequence, as shown.


Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See “Capacities and Specifications” in the index for the wheel nut torque specification. Don’t try to put a wheel cover on your compact spare tire. It won’t fit. Store the wheel cover and wheel nut caps in the trunk until you have the flat tire repaired or replaced. Notice: Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare.


Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See ”Capacities and Specifications” in the Index for wheel nut torque specification.

Compact Spare Tire 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 kPa). 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 wheel 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.

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 on fabric after spot cleaning, clean the entire area immediately or it will set.


Using Cleaner on Fabric 1. Vacuum and brush the area to remove any loose dirt. 2. Always clean a whole trim panel or section.


Mask surrounding trim along stitch or welt lines.


3. Follow the directions on the container label. 4. Apply cleaner with a clean sponge. Don’t saturate


the material and don’t rub it roughly.


5. As soon as you’ve cleaned the section, use a


sponge to remove any excess cleaner.


6. Wipe cleaned area with a clean, water-dampened


towel or cloth.
