Hazard Warning Flashers
The button for the hazard warning flashers is located on top of the steering column.
The hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. Press the button all the way down to make your front and rear turn signal lamps flash on and off. To turn off the flashers, press the button again until it clicks and then release it. When the hazard warning flashers are on, the turn signals won’t work.
Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (100 m) behind your vehicle.
Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.
5-2
Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. But please use the following steps to do it safely.
CAUTION:
Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you.
NOTICE:
Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty. The ACDelcoR battery in your vehicle has a built-in hydrometer. Do not charge, test or jump start the battery if the hydrometer looks clear or light yellow. Replace the battery when there is a clear or light yellow hydrometer and a cranking complaint. Trying to start your vehicle by pushing or pulling it won’t work, and it could damage your vehicle.
5-3
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
NOTICE:
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 transmission in PARK (P) or a manual transmission in NEUTRAL before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL (N).
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 accessory power outlets (if equipped). Turn off the radio and all lamps that aren’t needed. This will avoid sparks and help to save both batteries. And it could save your radio!
4. Open both hoods and locate the batteries. Find the
positive (+) and negative (-) terminals on each battery. Your vehicle has a remote negative (-) jump starting terminal. You should always use this remote terminal instead of the terminal on the battery. The remote negative (-) terminal is located on the front engine lift bracket and is marked “GND.†See “Engine Compartment Overview†in the Index for more information on location.
5-4
CAUTION:
CAUTION:
Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don’t need to add water to the ACDelcoR battery installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. 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.
Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.
5. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (-) will go to a heavy, unpainted metal engine part or to a remote negative (-) terminal if the vehicle has one. 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.
5-5
6. Connect the red
positive (+) cable to the positive (+) terminal of the dead 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 (-) terminal if the vehicle has one.
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.
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 the remote negative (-) terminal on the vehicle with the dead battery. The remote negative (-) terminal on your vehicle is located on the front engine lift bracket and is marked “GND.â€
5-6
9. Connect the other end of the negative (-) cable to the remote negative (-) terminal on the vehicle with the dead battery.
11. 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 they don’t touch each other or any other metal. The repairs wouldn’t be covered by your warranty.
10. Now start the vehicle with the good battery and run
the engine for a while.
5-7
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.
Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your vehicle towed. See “Roadside Assistance†and “Recreational Vehicle Towing†in the Index.

Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. See “Gages†in the Index. If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.
NOTICE:
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.
5-9
If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: D Climb a long hill on a hot day. D Stop after high-speed driving. D Idle for long periods in traffic. D Tow a trailer. See “Driving on Grades†in the Index. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If your air conditioner is on, turn it off. 2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while driving -- DRIVE (D) or THIRD (3).
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, push down the accelerator until the engine speed is about twice as fast as normal idle speed for at least 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.
5-10
Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see:
A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Fan
If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down.
When the engine is cold, the coolant level should be at least up to the FULL COLD mark. If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.
5-11
NOTICE:
Engine damage from running your engine without coolant isn’t covered by your warranty.
NOTICE:
When adding coolant, it is important that you use only DEX-COOLR (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-COOLR is not covered by your new vehicle warranty.
If there seems to be no leak, start the engine again. See if the engine cooling fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.
5-12
How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOLR engine coolant at the coolant recovery tank. See “Engine Coolant†in the Index for more information.
CAUTION:
Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. 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, drinkable water and DEX-COOLR coolant.
NOTICE:
CAUTION:
In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.
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 the coolant in the coolant recovery tank is at the FULL COLD mark, start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mixture directly to the radiator, but be sure the cooling system is cool before you do it.
5-13
CAUTION:
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 radiator pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.
5-14
How to Add Coolant to the Radiator
2. Then keep turning the pressure cap. Remove the
pressure cap.
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
5-15
3. Fill the radiator with the proper DEX-COOLR
coolant mixture, up to the base of the filler neck. See “Engine Coolant†in the Index for more information about the proper coolant mixture.
4. Then fill the coolant recovery tank to the
FULL COLD mark.
5. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.
5-16
Engine Fan Noise This vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions the clutch is not engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases when the clutch engages. So you may hear an increase in fan noise. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages. You may also hear this fan noise when you start the engine. It will go away as the fan clutch disengages.
5-17
6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the engine cooling fan.
7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOLR coolant mixture through the filler neck until the level reaches the base of the filler neck.
8. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure the pressure cap is hand-tight.
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.
5-18
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive gear -- not in NEUTRAL.
4. Turn off the engine. 5. Put the wheel 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.
Removing the Spare Tire and Tools
The following steps will tell you how to use the jack and change a tire.
The jacking equipment you will need is stored under the rear seat of the vehicle. See “Rear Seats†in the Index for more information on accessing the jacking equipment under the rear seat.
5-19
The tools you’ll be using include the wheel wrench (A), tire blocks (B), extension (socket end) (C), handle (jack end) (D), and jack (E). The following instructions explain how to remove the spare tire mounted underneath your vehicle.
NOTICE:
Never remove or restow a tire from/to a stowage position under the vehicle while the vehicle is supported by a jack. Always tighten the tire fully against the underside of the vehicle when restowing.
5-20
1. To remove the underbody-mounted spare, insert the
socket end of the extension, on an angle, into the hole in the rear bumper. Be sure the socket end of the extension connects into the hoist shaft.
2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until the spare tire can be pulled out from under the vehicle. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower. See “Secondary Latch System†later in this section. When the tire has been completely lowered, tilt the retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the vehicle before the cable is properly stored.
3. Put the spare tire near the flat tire.
4. Use the chisel end of the wheel wrench to pry off
the center cap.
See “Removing the Flat Tire and Installing the Spare Tire†later in this section to continue changing the flat tire.
5-21
Secondary Latch System The spare tire hoist assembly is equipped with a secondary latch system. It’s designed to stop the spare tire from suddenly falling off your vehicle. For the secondary latch to work, the spare tire must be stored with the valve stem pointing up. See “Storing a Flat or Spare Tire and Tools†in the Index for instructions on storing the spare tire correctly.
CAUTION:
Before beginning this procedure, read all the instructions. Failure to read and follow the instructions could damage the hoist assembly and you and others could get hurt. Read and follow the instructions listed below.
5-22
To release the spare tire from the secondary latch do the following:
1. Check under the
vehicle to see if the cable is visible.
2. If it is not visible, proceed to Step 6.
If visible, first try to tighten the cable by turning the wheel wrench clockwise until you hear two clicks or feel it skip twice. You cannot overtighten the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with Step 2 of “Removing the Spare Tire and Tools†earlier in this section.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.
8. Continue raising the jack until the spare tire
stops moving upward and is held firmly in place. The secondary latch has released and the spare tire is balancing on the jack.
9. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until the spare tire slides off the jack or is hanging by the cable.
CAUTION:
Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from under the spare.
5-23
6. Attach the jack handle, extension and the wheel wrench to the jack and place it under the vehicle towards the front of the rear bumper. Position the center lift point of the jack under the center of the spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end fitting.
10. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push against the spare while firmly pulling the jack out from under the spare tire with the other hand.
11. Tilt the retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle.
12. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can. You will not be able to store a spare or flat tire using the hoist assembly until it has been repaired or replaced. To continue changing the flat tire, return to Step 2 of “Removing the Spare Tire and Tools†earlier in this Section.
If the spare tire is hanging from the cable, insert the jack handle, extension and wheel wrench into the hoist shaft hole in the bumper, on an angle, and turn the wheel wrench counterclockwise to lower the spare the rest of the way.
5-24
Removing the Flat Tire and Installing the Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don’t remove them yet.
2. Turn the jack adjusting knob clockwise by hand to
raise the jack lift head.
3. Place the handle, extension and wheel wrench onto
the jack.

4. Place the jack in the appropriate position nearest the
flat tire.
CAUTION:
Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.
5. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit.
6. Remove all the wheel nuts and take off the flat tire.
5-27
7. Remove any rust or dirt
from the wheel bolts, mounting surfaces and spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.
5-28
CAUTION:
Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.
8. Place the spare on the wheel mounting surface.
9. Put the nuts on by hand. Make sure the rounded end is toward the wheel.
10. Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the wheel wrench and see your dealer as soon as possible.
11. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely.
12. Use the wrench to
tighten the wheel nuts firmly in a crisscross sequence as shown.
CAUTION:
Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become 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 100 lb-ft (140 N·m).
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.
5-29
Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.
CAUTION: (Continued)
your vehicle. If this happened when your vehicle was being driven, the tire might contact a person or another vehicle, causing injury and, of course, damage to itself as well. Be sure the underbody-mounted spare or flat road tire is stored with its valve stem pointing up.
CAUTION:
NOTICE:
The underbody-mounted spare tire or flat road tire needs to be stored with the valve stem pointing up. If the tire is stored with its valve stem pointing downward, its secondary latch won’t work properly, and the spare tire or flat road tire could loosen and suddenly fall from
CAUTION: (Continued)
An aluminum wheel with a flat tire should always be stored under the vehicle with the hoist. However, storing it that way for an extended period could damage the appearance of the wheel. To avoid this, always stow the wheel properly with the valve stem pointing up and have the tire repaired as soon as possible.
5-30
Follow this diagram to store the underbody-mounted spare.
A. Wheel Wrench B. Hoist Shaft C. Extension D. Retainer E. Spare or Flat Tire
(Valve Stem Pointed Up)
1. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed up and to the rear.
2. Pull the retainer through the wheel. 3. Put the socket end of the extension, on an angle, through the hole in the rear bumper and into the hoist shaft.
4. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until the tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.
5. Make sure the tire is stored securely. Push, pull, and
then try to rotate or turn the tire. If the tire moves, use the wheel wrench to tighten the cable.
5-31
If You’re Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking†can help you get out when you’re stuck, but you must use caution.
CAUTION:
If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer.
Return the jack, wheel wrench and wheel blocks to the proper location under the rear seat of the vehicle. Secure the items and return the rear seat to its proper position.

Using the Recovery Hooks
Your vehicle may be 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 some place where you can continue driving.
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. If you have a four-wheel-drive vehicle, shift into 4HI. 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. By slowly spinning your wheels in the forward and reverse directions, you will cause a rocking motion that may free your vehicle. 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.
5-33
CAUTION:
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.
NOTICE:
Never use the recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.

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 and Owner Publications†in the Index. Your vehicle has an air bag system. Before attempting to 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.
6-2
CAUTION:
You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. D Be sure you have sufficient knowledge,
experience, the proper replacement parts and tools before you attempt any vehicle maintenance task.
D Be sure to use the proper nuts, bolts and other fasteners. “English†and “metric†fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
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. Fuel 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 it is bad enough, it can 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.
6-3
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. Gasolines meeting these specifications could provide improved driveability and emission control system performance compared to other gasolines.
In Canada, look for the “Auto Makers’ Choice†label on the pump.
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 Indicator Lamp†in the Index) 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.
Canada Only
6-4
Additives 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. 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 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 warranty. 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.
6-5
Filling Your Tank
CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.
The fuel cap is located behind a hinged door on the
driver’s side of your vehicle.
6-6
While refueling, hang the fuel cap by the tether using the hook located on the inside of the filler door. To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap has a spring in it; if you let go of the cap too soon, it will spring back to the right.
CAUTION:
If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss†noise to stop. Then unscrew the cap all the way.
Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Vehicle†in the Index.
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 Indicator Lamp†in the Index.
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 Indicator Lamp†in the Index.
6-7
Filling a Portable Fuel Container
Checking Things Under the Hood
CAUTION:
CAUTION:
Things that burn can get on hot engine parts and start a fire. These include liquids like fuel, 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: D Dispense gasoline only into
approved containers.
D Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground. D 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.
D Don’t smoke while pumping gasoline.
6-8
Hood Release
1. To open the hood, first pull the handle located inside the vehicle on the lower driver’s side of the instrument panel.
2. Then go to the front of the vehicle and release the
secondary hood release.
3. Lift the hood, release the hood prop from its retainer
and put the hood prop into the slot in the hood. There may be a lamp that comes on when you open the hood.
6-9
Engine Compartment Overview When you open the hood you’ll see the following:
6-10
A. Coolant Recovery Tank B. Engine Air Cleaner/Filter C. Windshield Washer Fluid Reservoir D. Engine Air Cleaner/Filter Indicator E. Power Steering Fluid Reservoir F. Automatic Transmission Dipstick G. Engine Oil Dipstick H. Radiator Pressure Cap I. Engine Oil Fill Cap J. Front Engine Lift Bracket Marked “GND†K. Brake Master Cylinder L. Battery M. Engine Compartment Fuse Block
Before closing the hood, be sure all filler caps are on properly. Then lift the hood to relieve pressure on the hood prop. Remove the hood prop from its slot in the hood and return the prop to its retainer. Then pull the hood down firmly to close. It will latch when dropped from 6 to 8 inches (15 to 20 cm) without pressing on the hood.
Engine Oil If the CHECK OIL LEVEL message appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see “Check Oil Level Message†in the Index. You should check your engine oil level regularly; this is an added reminder. 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 handle is a yellow ring located in the engine compartment toward the passenger’s side of the vehicle. See “Engine Compartment Overview†in the Index for more information on location.
6-11
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. 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.
NOTICE:
Don’t add too much oil. If your engine has so much oil that the oil level gets above the F mark that shows the proper operating range, your engine could be damaged.
The engine oil fill cap is located in the engine compartment toward the passenger’s side of the vehicle. See “Engine Compartment Overview†in the Index for more information on location.
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.
When to Add Engine Oil If the oil is at or below the L mark, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications†in the Index.
6-12
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 change your own oil, be sure you use oil that 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 following chart:
6-13
As in the chart shown previously, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0_F (-18_C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.
GM GoodwrenchR 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 0W-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 Your vehicle has a computer that lets you know when to change your engine oil. This is not based on mileage, but on engine revolutions and engine operating temperature. When the computer has calculated that the oil needs changing, the GM Oil Life Systemt will indicate that a change is necessary. The mileage between oil and filter changes will vary depending on how you drive your vehicle -- usually between 3,000 miles (5 000 km) and 12,000 miles (20 000 km) since your last oil and filter change. Under severe conditions, the system may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 12,000 miles (20 000 km) or 12 months (whichever occurs first) without an oil change. The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5 000 km) or sooner. Remember to reset the CHANGE ENG OIL light whenever the oil is changed.
6-14
How to Reset the CHANGE ENG OIL Light To reset the CHANGE ENG OIL light, do the following: 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal
three times within five seconds. If the CHANGE ENG OIL light flashes for five seconds, the system is reset. If the light does not flash, repeat the procedure.
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 dealer, a service station or a local recycling center for help.
6-15
Engine Air Cleaner/Filter
The engine air cleaner/filter is located toward the front of the engine compartment on the passenger’s side of the vehicle.
The engine air cleaner/filter assembly has an indicator that lets you know when the air filter is dirty and needs to be serviced. The indicator is located on the engine air cleaner/filter air duct.
See “Engine Compartment Overview†in the Index for more information on engine air cleaner/filter location.
See “Engine Compartment Overview†in the Index for more information on engine air cleaner/filter indicator location. The service window (A) with the percentage scale shows the amount of engine air cleaner/filter life used. When both service window (A) and service window (B) turn orange, replace the engine air cleaner/filter.
6-16
After changing the engine air cleaner/filter, press the button on top of the indicator to reset it. See “Owner Checks and Services†in the Index to determine when to check the indicator. To replace the engine air cleaner/filter, do the following: 1. Remove the three screws on the engine air
cleaner/filter and lift off the cover.
2. Twist out the old engine air cleaner/filter and replace
it with a new one. 3. Reinstall the cover.
CAUTION:
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.
6-17
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 50,000 miles (83 000 km) if the vehicle is mainly driven under one or more of these conditions: D In heavy city traffic where the outside temperature
regularly reaches 90_F (32_C) or higher.
D In hilly or mountainous terrain. D When doing frequent trailer towing. D 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 100,000 miles (166 000 km). See “Scheduled Maintenance Services†in the Index.
6-18
How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership 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 transmission. 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. Too little fluid could cause the transmission to overheat. 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: D When outside temperatures are above 90_F (32_C). D At high speed for quite a while. D In heavy traffic -- especially in hot weather. D 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). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50_F (10_C). If it’s colder than 50_F (10_C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this 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 (10_C), you may have to idle the engine longer. Should the fluid level be low during this cold check, you must check the fluid hot before adding fluid. Checking the fluid hot will give you a more accurate reading of the fluid level.
Checking the Fluid Level Prepare your vehicle as follows: D Park your vehicle on a level place. Keep the
engine running.
D With the parking brake applied, place the shift lever
in PARK (P).
D 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).
D Let the engine run at idle for three minutes or more.
6-19
Then, without shutting off the engine, follow these steps:
Locate the handle with the transmission and lock symbols for the automatic transmission dipstick in the engine compartment on the passenger’s side of the vehicle.
See “Engine Compartment Overview†in the Index for more information on location. 1. Flip the handle up and then pull out the dipstick and
wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
6-20
3. 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.
How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants†in the Index. Add fluid only after checking the transmission fluid while it is hot. (A cold check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill.
NOTICE:
We recommend you use only fluid labeled DEXRONR-III, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRONR-III is not covered by your new vehicle warranty.
D After adding fluid, recheck the fluid level as
described under “How to Check.â€
D 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.
Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Scheduled Maintenance Services†in the Index.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a level surface. The proper level is from 0 to 3/8 inch (0 to 10 mm) below 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.
6-21
How to Check Lubricant
Four-Wheel Drive Lubricant checks in this section also apply to these vehicles. However, there are two additional systems that need lubrication. Transfer Case
When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections†in the Index.
To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. Use care not to overtighten the plug.
What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants†in the Index.
6-22
Front Axle
When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See “Scheduled Maintenance Services†in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole, you may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole.
What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants†in the Index.
To get an accurate reading, the vehicle should be on a level surface.
6-23
NOTICE:
When adding coolant, it is important that you use only DEX-COOLR (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-COOLR is not covered by your new vehicle warranty.
Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating†in the Index. A 50/50 mixture of clean, drinkable water and DEX-COOLR coolant will: D Give freezing protection down to -34_F (-37_C). D Give boiling protection up to 265_F (129_C). D Protect against rust and corrosion. D Help keep the proper engine temperature. D Let the warning lights and gages work as
they should.
6-24
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOLR coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else.
CAUTION:
Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. 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, drinkable water and DEX-COOLR coolant.
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.
6-25
Checking Coolant
The engine coolant recovery tank is in the engine compartment on the passenger’s side of the vehicle. See “Engine Compartment Overview†in the Index for more information on location.
The vehicle must be on a level surface. When your engine is cold, the coolant level should be at FULL COLD, or a little higher. When your engine is warm, the level should be at the base of the filler neck or a little higher.
Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the coolant recovery tank.
CAUTION:
Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. 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.
6-26
Add coolant mixture at the recovery tank, but be careful not to spill it.
Radiator Pressure Cap
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.
Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see “Cooling System†in the Index.
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.
See “Engine Compartment Overview†in the Index for information on location.
6-27
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 C (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 “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.
Power Steering Fluid
The power steering fluid reservoir is located in the engine compartment on the passenger’s side of the vehicle.
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. See “Engine Compartment Overview†in the Index for reservoir location.
6-28
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. See “Engine Compartment Overview†in the Index for reservoir location. Adding Washer Fluid
Open the cap with the washer symbol on it. Add washer fluid until the tank is full.
NOTICE:
D When using concentrated washer fluid,
follow the manufacturer’s instructions for adding water.
D 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.
D 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.
D Don’t use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint.
6-29
Brakes Brake Fluid
Your brake master cylinder reservoir is filled with DOT-3 brake fluid. See “Engine Compartment Overview†in the Index for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up.
6-30
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 off†your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.
CAUTION:
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. See “Checking Brake Fluid†in this section.
Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections†in the Index.
Checking Brake Fluid
You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. 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.
What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to “Recommended Fluids and Lubricants†in the Index. Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir.
CAUTION:
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.
6-31
NOTICE:
D 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.
D 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.
6-32
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).
CAUTION:
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.
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. Brake linings should always be replaced as complete axle sets. See “Brake System Inspection†in Section 7 of this manual under Part C “Periodic Maintenance Inspections.†Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.
Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is complex. 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 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.
6-33
Battery Your new vehicle comes with a maintenance free ACDelcoR 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†in the Index 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.
CAUTION:
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting†in the Index for tips on working around a battery without getting hurt.
Contact your dealer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature†in the Index.
6-34

Backglass Wiper Blade Replacement See “Windshield Wiper Blade Replacement†in this section for instructions on how to change the backglass wiper blade. 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 manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your Chevrolet Warranty booklet for details.

CAUTION:
Poorly maintained and improperly used tires are dangerous. D Overloading your tires can cause
overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle†in the Index.
D 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.
D 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.
D Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have been damaged, replace them.
Inflation -- Tire Pressure The Certification/Tire 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 (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: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards
When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire.
How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. 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 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires†and “Wheel Replacement†later in this section for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench to tighten the cable. See “Storing a Flat or Spare Tire and Tools†in the Index. 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 “Scheduled Maintenance Services†in the Index for scheduled rotation intervals.
6-40
When rotating your tires, always use one of the correct rotation patterns shown here. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque†in the Index.
CAUTION:
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
One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.
You need a new tire if any of the following statements are true: D You can see the indicators at three or more places
around the tire.
D You can see cord or fabric showing through the
tire’s rubber.
D The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
D The tire has a bump, bulge or split. D 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 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).
