Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground.


Trailer Brakes If your trailer weighs more than 1,000 lbs. (450 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Your trailer brake system can tap into your vehicle’s hydraulic brake system, except: D Don’t tap into your vehicle’s brake system if the trailer’s brake system will use more than 0.02 cubic inch (0.3 cc) of fluid from your vehicle’s master cylinder. If it does, both braking systems won’t work well. You could even lose your brakes. D Will the trailer parts take 3,000 psi (20 650 kPa) of


pressure? If not, the trailer brake system must not be used with your vehicle.


D If everything checks out this far, then make the brake fluid tap at the port on the master cylinder that sends fluid to the rear brakes. But don’t use copper tubing for this. If you do, it will bend and finally break off. Use steel brake tubing.


4-37


Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check the trailer hitch and platform (and attachments), safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.


Driving with a Trailer


CAUTION:


If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You can’t see or smell CO. It can cause unconsciousness or death. See “Engine Exhaust” in the Index. To maximize your safety when towing a trailer: D Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip.


D Keep the rear-most windows closed. D If exhaust does come into your vehicle


through a window in the rear or another opening, drive with your front, main heating or cooling system on and with the fan on any speed. This will bring fresh, outside air into your vehicle. Do not use MAX A/C because it only recirculates the air inside your vehicle. See “Comfort Controls” in the Index.


4-38


Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.


Making Turns


NOTICE:


Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering.


When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.


4-39


Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have extra wiring (included in the optional trailering package). The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working.


Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. You can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). See “Tow/Haul Mode” in the Index. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked (preferably on level ground) with the automatic transmission in PARK (P) for a few minutes before turning the engine off. If you do get the overheat warning, see “Engine Overheating” in the Index.


4-40


Parking on Hills


CAUTION:


You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged.


But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into


PARK (P) yet.


2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.


4. Reapply the regular brakes. Then apply your parking


brake, and shift to PARK (P).


5. Release the regular brakes.


When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down


while you: D start your engine, D shift into a gear, and D release the parking brake.


2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transmission fluid (don’t overfill), engine oil, axle lubricant, 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 these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.


4-41


The technician can use the following color code chart when connecting the wiring harness to your trailer. D Brown: Rear lamps. D Yellow: Left stoplamp and turn signal. D Dark Green: Right stoplamp and turn signal. D White (Heavy Gage): Ground. D Light Green: Back-up lamps. D White (Light Gage): Center High-Mounted


Stoplamp.


D Blue: Auxiliary circuit (eight-wire harness only). D Orange: Fused auxiliary (eight-wire harness only).


Store the harness in its original place. Wrap the harness together and tie it neatly so it won’t be damaged.


Trailer Wiring Harness If you have the optional trailering package, your vehicle will have an eight-wire harness, including the center high-mounted stoplamp battery feed wire. The harness is stored on the passenger’s side of the vehicle near the rear wheel well. This harness has a 30 amp battery feed wire and no connector, and should be wired by a qualified electrical technician. After choosing an aftermarket trailer mating connector pair, have the technician attach one connector to the eight-wire trailer harness and the other connector to the wiring harness on the trailer. Be sure the wiring harness on the trailer is taped or strapped to the trailer’s frame rail and leave it loose enough so the wiring doesn’t bend or break, but not so loose that it drags on the ground. The eight-wire harness must be routed out of your vehicle between the rear door and the floor, with enough of the harness left on both sides so that the trailer or the body won’t pull it. If you do not have the optional trailering package, your vehicle will still have a trailering harness. The harness is located near the passenger’s side rear wheel well. It consists of six wires that may be used by after-market trailer hitch installers.

Hazard Warning Flashers


The hazard warning flasher button is located on top of the steering column. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. Press the button to make the front and rear turn signal lamps flash on and off. Press the button again to turn the flashers off. When the hazard warning flashers are on, your turn signals won’t work.


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


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. 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 follow the numbered 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.


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.


5-3


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) and a manual transmission in NEUTRAL.


3. Turn off the ignition on both vehicles. Unplug


unnecessary accessories plugged into the cigarette lighter or accessory power outlets. Turn off all lamps that aren’t needed as well as radios. This will avoid sparks and help save both batteries. In addition, it could save your radio!


NOTICE:


If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty.


4. Open the hoods and locate the batteries. Find the positive (+) and negative (-) terminals on each battery.


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.


5-4


CAUTION:


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 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.


6. Connect the red


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


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.


5-5


10. Now start the vehicle with the good battery and run


the engine for a while.


11. Try to start the vehicle with 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.


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. Don’t let the other end touch anything until the next step.


The other end of the negative (-) cable does not 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.


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.


5-6


Jumper Cable Removal A. Heavy, Unpainted Metal Engine Part B. Good Battery C. Dead Battery


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 disabled vehicle towed. See “Roadside Assistance” in the Index. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see “Recreational Vehicle Towing” in the Index. Engine Overheating You will find an engine coolant temperature gage on your vehicle’s instrument panel. See “Gages” in the Index.


5-7


If Steam Is Coming From Your Engine


5-8


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.


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 you have an air conditioner and it’s 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 -- AUTOMATIC OVERDRIVE (B) or DRIVE (D).


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.


5-9


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


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


The coolant level should be at the ADD mark.


If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.


A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Cooling Fan


5-10


CAUTION:


NOTICE:


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.


If there seems to be no leak, start the engine again. The engine cooling fan speed should increase when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.


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.


5-11


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 ADD 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.


NOTICE:


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.


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.


5-12


CAUTION: (Continued)


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.


CAUTION:


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


When the coolant in the coolant recovery tank is at the ADD 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.


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


CAUTION: (Continued)


5-13


2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap.


How to Add Coolant to the Radiator


You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot.


1. Turn the pressure cap slowly counterclockwise


until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.


5-14


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 ADD mark. 5. Put the cap back on the coolant recovery tank, but


leave the pressure cap off.


5-15


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 arrow on the pressure cap lines up like this.


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.


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 fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases 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.


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.


5-17


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


CAUTION:


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


1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine. 4. 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.


5-18


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


Removing the Spare Tire and Tools


The jacking equipment you’ll need is stored by your vehicle’s rear doors, along the passenger’s side wall. 1. Remove the jack cover by pulling it away from the side wall and down to release the tabs securing the top of the cover.


2. Remove the wheel blocks by turning the top nut


counterclockwise. Remove the nut and washer, then pull the wheel blocks off the bolt.


3. Push down on the bolt and remove the hooked end from the slot. Slide the jack toward the front of the vehicle and lift it from the mounting. Remove the extension and the ratchet from the pouch.


5-19


The ratchet has an UP side.


It also has a DOWN side.


Your compact spare tire is stored underneath the rear of your vehicle. You will use the ratchet and extension to lower the compact spare tire.


4. Attach the ratchet, with the DOWN side facing you, to the extension. The extension has a socket end and a flat chisel end.


5-20


5. Put the flat end of the extension on an angle through


the hole in the rear door frame, above the bumper. Be sure the flat end connects into the hoist shaft.


7. When the tire has been lowered, tilt the retainer plate at the end of the cable and pull it through the wheel opening.


8. Pull the tire out from under the vehicle.


NOTICE:


To help avoid vehicle damage, do not drive the vehicle before the cable is restored.


6. Turn the ratchet counterclockwise to lower the


compact spare tire to the ground. Keep turning the ratchet until the spare tire can be pulled out from under the vehicle.


5-21


Removing the Wheel Covers You will have to take off hub caps or wheel nut caps to reach your wheel nuts.


The tools you’ll be using include the jack (A), wheel blocks (B), extension (C) and ratchet (D).


5-22


Styled Steel Wheel Shown


If you have the styled steel wheel or aluminum wheel with plastic nut caps, loosen the plastic nut caps with the ratchet and socket. Make sure the DOWN side faces you. To remove the hub cap from the aluminum wheel without plastic nut caps, fit the flat end of the extension into the notch. Then, remove the center cap.


Removing the Flat Tire and Installing the Spare Tire


1. Before you start, block the front and rear of the tire farthest away from the one being changed. Then put your compact spare tire near the flat tire.


2. With the DOWN side facing you, use the ratchet and


socket to loosen all the wheel nuts. Don’t remove them yet.


3. The jack has a bolt on the end. Attach the socket end


of the extension to the jack bolt.


5-23


4. Attach the ratchet to the extension with the UP side


facing you.


5. Turn the ratchet clockwise. That will raise the jack


lift head a little.


6. Position the jack under the vehicle.

CAUTION:


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.


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.


5-26


7. Raise the vehicle by turning the ratchet clockwise.


Make sure the UP mark faces you. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit underneath the wheel well.


8. Remove all the wheel nuts and take off the flat tire.


9. 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.


5-27


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.


10. Put on the compact spare tire. Put the nuts on by


hand. Make sure the cone-shaped end is toward the wheel. Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the extension and see your dealer as soon as possible.


5-28


11. Lower the vehicle by turning the ratchet


counterclockwise. Lower the jack completely.


12. Tighten the wheel


nuts firmly in a crisscross sequence as shown. Turn the ratchet clockwise with the UP mark facing you.


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.


13. Remove the wheel blocks.


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.


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.


1. Put the flat tire on the ground at the rear of the


vehicle with the valve stem pointed down.


2. Tilt the retainer plate downward and through the


wheel opening. Make sure it is fully seated across the underside of the wheel. Attach the ratchet, with the UP side facing you, to the extension.


3. Put the flat end of the extension on an angle through


the hole in the rear door frame, above the bumper. Keep turning the ratchet until you feel at least two clicks when the tire is up all the way. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See “Compact Spare Tire” in the Index. See the storage instructions label to restore your compact spare properly.


4. Raise the tire fully against the underside of the


vehicle. Continue turning the ratchet/wheel wrench until the tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.


5-30


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.

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 ratchet/wheel wrench to tighten the cable. Return the jacking equipment to its proper location.


NOTICE:


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.


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.


5-32


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.


NOTICE:


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


For information about using tire chains on your vehicle, see “Tire Chains” in the Index. Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. 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. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

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 fuel pump.


Canada Only


6-4


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. 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. 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.


6-5


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


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.


6-6


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.

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.

Hood Release


To open the hood, do the following: 1. Pull the handle located inside the vehicle on the


lower driver’s side of the kick panel.


2. Then go to the front of the vehicle and release the


secondary hood release.


6-9


Before closing the hood, be sure all the filler caps are on properly. Then lift the hood to relieve pressure on the hood prop and remove the hood prop from the slot in the hood.


Return the prop to its retainer.


3. Lift the hood, release the hood prop from its retainer


and put the hood prop into the slot in the hood.


Then just pull the hood down and close it firmly.

G. Brake Master Cylinder Reservoir H. Power Steering Fluid Reservoir I. Battery


6-11


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 has a yellow ring and is located near the center of the engine compartment. See “Engine Compartment Overview” in the Index for more information on location. 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.


6-12


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


NOTICE:


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


The engine oil fill cap is located on the valve cover in the engine compartment on the passenger’s side of the vehicle. Your vehicle may have a cap with text and a graphic or just a graphic as shown above. 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.


6-13


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:


6-14


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 If any one of these is true for you, use the short trip/city maintenance schedule: D Most trips are less than 5 miles (8 km). This is


particularly important when outside temperatures are below freezing.


D Most trips include extensive idling (such as frequent


driving in stop-and-go traffic).


D You frequently tow a trailer or use a carrier on top


of your vehicle.


D 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 the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower.


6-15


Engine Cover Removing the Engine Cover 1. Move both front seats as far back as they will go.


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 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 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.


6-16


2. Remove the instrument panel extension by removing


the two nuts that secure it in place. The nuts are located at the bottom of the extension on the driver’s and passenger’s side corners.


3. Remove the screws located near the top on each side of the extension. Grasp the extension from both sides and gently remove it.


6-17


4. Disconnect the electrical connectors and set the


extension aside.


5. Grasp the top of the heater duct and pull down gently


to remove it.


6-18


6. Loosen the two bolts on the engine cover. The bolts are not supposed to come out of the cover, only from the front of the dash. When removing the cover, be careful not to damage the instrument panel or the trim.


7. Disconnect the AM radio ground strap.


8. Grasp the bottom of the cover and slide it rearward.


Then, lift it up and out of the vehicle. If the seal does not release, use the pull strap on the driver’s side above the rear mount.


6-19


Engine Air Cleaner/Filter Refer to the Maintenance Schedule to determine when to replace the engine air cleaner/filter and the crankcase ventilation filter. See “Scheduled Maintenance” in the Index. See “Engine Compartment Overview” in the Index for more information on location.


Reinstalling the Engine Cover 1. Lift the engine cover into the front of the vehicle


and slide it all the way forward. Make sure the rubber seal is over the latches.


2. Tighten the two bolts located on the engine cover


to reinstall the cover to the front of the dash.


3. Put the heater duct over the engine cover studs.


Push up on the duct gently until it snaps into place.


4. Reconnect the electrical connectors. 5. Reconnect the AM radio ground strap. 6. Reinstall the engine cover extension by gently


squeezing the sides and sliding it into place. Make sure all of the fastener clips engage and the extension fits properly in place. Reinstall and tighten the two screws.


7. Reinstall the two nuts to secure the extension


in place.


6-20


To change the engine air cleaner/filter, do the following: 1. Unsnap both clips on the cover. 2. Remove the cover. 3. Change the filter. 4. Snap both clips to secure the engine air


cleaner/filter cover.


Be sure the engine air cleaner/filter cover is correctly positioned to seal out dust and contaminants that are harmful to your engine.


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.


6-21


Automatic Transmission Fluid When to Check and Change A good time to check your automatic transmission fluid level is when the engine oil is changed. Change both the fluid and filter every 15,000 miles (25 000 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 50,000 miles (83 000 km). See “Scheduled Maintenance Services” in the Index.


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.


6-22


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.


6-23


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


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.


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


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


The transmission dipstick has a red handle and is located near the center of the engine compartment behind the air cleaner. See “Engine Compartment Overview” in the Index for more information on location.


6-24


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


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


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.”


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.


6-25


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.


6-26


If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index.


All-Wheel Drive Lubricant checks in this section also apply to these vehicles. However, there are two additional systems that need lubrication.


Transfer Case


When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index.


How to Check Lubricant To get an accurate reading, the vehicle should be on a level surface.


If the level is below the bottom of the filler plug hole, you’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.


6-27


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 To get an accurate reading, the vehicle should be on a level surface.


If the level is below the bottom of the filler plug hole, you may need to add some lubricant.


When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole.


What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index.


6-28


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.


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.


6-29


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.


6-30


Checking Coolant


The engine coolant tank is located in the engine compartment on the passenger’s side at the front. 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 ADD, or a little higher. When your engine is warm, the level should be up to FULL HOT, 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.


6-31


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:


The radiator pressure cap is located in the engine compartment on the passenger’s side of the vehicle.


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


6-32


Power Steering Fluid


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.


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 “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.


6-33


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 fill tank is located in the engine compartment on the passenger’s side of the vehicle. See “Engine Compartment Overview” in the Index for more information on location.


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.

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.


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.

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.


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.


6-36


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.


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).


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.


6-37


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” 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. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by backing up and firmly applying the brakes a few times. 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.

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.
