2003 Oldsmobile Aurora Owners Manual

you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-33. Dit-! and water can also enter the vehicle.

Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer 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. And, never allow safety chains to drag on the ground.

4-39

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. 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.

Trailer Brakes Does your trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Because you have anti-lock brakes, do not try to tap into your vehicle’s brake system. If you do, both brake systems won’t work well, or at all. Trailer Wiring Harness All of the electrical circuits required for your trailer lighting system can be accessed at the driver’s side rear lamp connector. This connector is located under the carpet in the rear corner of the trunk compartment. Driving with a Trailer 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.

4-40

Turn Signals When Towing a Trailer When you tow a trailer, your vehicle may need a different turn signal flasher and/or extra wiring. Check with your dealer. 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.

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 advance.

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. r-Irking on Hills

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 then shift to PARK (P).

5. Release the regular brakes.

4-42

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

while you:

start your engine, shift into a gear, and 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 transaxle fluid (don’t overfill), engine oil, drive belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly. If you’re trailering, it’s a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-28.

Doing Your Own Service Work

If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information on page 7-9. Your vehicle has an air bag system. Before attempting to do your own service work, see Servicing Your Air Bag-Equipped Vehicle on page 1-54. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See Part E: Maintenance Record on page 6- 16.

5-4

You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it.

Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.

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 Use of the recommended fuel is an important part of the proper maintenance of your vehicle. Gasoline Octane Use regular unleaded gasoline with a posted octane of 87 or higher. However, for best performance and for trailer towing, you may wish to use middle grade or premium unleaded gasoline. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine.

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

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

Canada Only

5-5

California Fuel If your vehicle is certified to meet California Emission Standards (see the underhood emission control label), it is designed to operate on fuels that meet California specifications. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on (see Malfunction Indicator Lamp on page 3-39 ) and your vehicle may fail a smog-check test. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty.

Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the specifications described earlier. Notice: Your vehicle was not designed for fuel that contains methanol. Don’t use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage wouldn’t be covered under your warranty.

5-6

Filling Your Tank

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

Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service.

Fuels in Foreign Countries

If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. ?2 check the !!x! 2xi!2bi!i?;, 2:sk 2 R 2ztc C ! k , cr contact a major oil company that does business in the country where you’ll be driving.

To open the fuel door, press the button located on the driver’s door trim near the trunk release button.

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

The ignition does not need to be on. The remote fuel door release will work in all transaxle positions. The trunk release lockout switch must be in OFF for the fuel door to open. The fuel door can be opened manually in case of a power failure. To do this, first open the trunk. The release mechanism is located on the driver’s side of the vehicle, at the top of the trunk compartment.

While refueling, hang the tethered fuel cap from the hook on the fuel 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 rinht a '3' '*.

5-9

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

Be careful not to spill fuel. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle on page 5-85. When filling the tank do not overfill by squeezing in much more fuel after the pump shuts off.

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 on page 3-39. The CHECK GAS CAP DIC message will come on if the fuel cap is not properly reinstalled.

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 *ontair -r

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

Dispense gasoline only into approved containers.

CAUTION:

Checking Things Under the Hood

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

/t\ 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.

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

The engine oil dipstick is located near the front of the engine compartment. The top of the dipstick is a round yellow loop. See Engine Companlment Overview on page 5-14 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.

5-1 6

When to Add Engine Oil If the oil is at or below the cross-hatched area at the tip of the dipstick, 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 on page 5- 100. Nofice: Don’t add too much oil. If your engine has so much oil that the oil upper mark that shows the proper operating range, your engine could be damaged.

Engine Oil (GM Oil

When to Change Life SystemTM) Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE OIL SOON message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the ysk?!?? !??est be reset. !t Is a!sc iy!crtm! ?c check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the ei! is changed.

5-1 9

How to Reset the Oil Life System The GM Oil Life SystemTM calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE OIL SOON message being turned on, reset the system. Always reset the engine Oil Life System to 100% after every oil change. It will not reset itself. To reset the OIL LIFE reminder, do the following:

1. With the ignition on, press the SELECT right arrow

on the DIC until you enter the OIL mode. The current OIL LIFE percentage will be displayed.

2. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show OIL LIFE XXX%. If OIL LIFE XXX% does not appear on the display after about five seconds, see your dealer for service. After you release the DIC RESET button, OIL LIFE 100% will appear on the display.

What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Engine Air Cleaner/Filter

The engine air cleanedfilter is in the engine compartment on the driver's side of the vehicle. See Engine Compartment Overview on page 5-14 for more information on location. I o check or replace the englne air cleaner/tilter do the following: 1. Unscrew the two wing screws on the outboard side

of the housing cover.

2. Remove the cover. 3. Remove the engine air cleanedfilter.

4. Install a new engine air cleanedfilter if needed. 5. Reverse Steps 1 and 2 to reinstall the cover.

Be sure the tabs of the cover fit into the slots of the housing.

See Part A: Scheduled Maintenance Services on page 6-4 to determine when to replace the air filter.

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 cleanedfilter off.

Automatic Transaxle Fluid When to Check and Change A good time to check your automatic transaxle 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:

In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. In hilly or mountainous terrain. When doing frequent trailer towing. Uses such as found in taxi, police or delivery service.

If you do not use your vehicle under any of these conditions, change the fluid and filter at 100,000 miles (1 66 000 km). See Part A: Scheduled Maintenance Services on page 6-4 for automatic transaxle fluid change intervals.

5-22

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 transaxle. Too much can mean that some of the fluid could come out and fall on hot engine or exhaust system parts, starting a fire. Too little fluid could cause the transaxle to overheat. Be sure to get an accurate reading if you check your transaxle fluid. Wait at least 30 minutes before checking the transaxle fluid level if you have been driving:

When outside temperatures are above 90°F (32°C). At high speed for quite a while. In heavy traffic - especially in hot weather. While pulling a trailer.

To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). 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 (lO"C), you may have to drive longer.

I

Checking the Fluid Level Prepare your vehicle as follows:

Park your vehicle on a level place. Keep the engine running. With the parking brake applied, place the shift lever in PARK (P).

e 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). Let the engine run at idle for three to five minutes.

Then, without shutting off the engine, follow these steps: The automatic transaxle fluid dipstick is located near the front of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-74 for more information on location. 1. 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 cross-hatched area.

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

dipstick back in all the way.

5-23

Engine Coolant The cooling system in your vehicle is filled with DEX-COOL@ engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see Engine Overheating on page 5-28. A 50/50 mixture of clean, drinkable water and DEX-COOL@ coolant will:

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

How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Part D: Recommended Fluids and Lubricants on page 6-15. If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick. 1, Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the

dipstick hole to bring it to the proper level. 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 DEXRON@-Ill, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON@-Ill is not covered by your new vehicle warranty. 3. After adding fluid, recheck the fluid level as

described under “How to Check,” earlier in this section.

4. When the correct fluid level is obtained, push the

dipstick back in all the way.

5-24

Notice: When adding coolant, it is important that you use only DEX-COOL@ (silicate-free) coolant. If coolant other than DEX-COOL@ is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50,000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOL@ is not covered by your new vehicle warranty. What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL@ coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else.

plain water to your cooling

Adding a system can be dangerous. Plain water, or some other liquid such as aicohol, 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-COOL@ 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 ana crack ihe engine, raiiiaiur, b a k r 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.

Checking Coolant

Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap - even a little - when the engine and radiator are hot.

The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the cold level mark.

The engine coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle, near the windshield. See Engine Compartment Overview on page 5-74 for more information on location.

When replacing the pressure cap, make sure the arrow lines up with the tube.

If the LOW ENGINE COOLANT DIC message comes on and stays on, it means you’re low on engine coolant. Adding Coolant If you need more coolant, add the proper DEX-COOL@ coolant mixture at the surge tank. but only when the engine is cool.

5-27

Coolant Surge Tank Pressure Cap The cooling system pressure cap is located on the surge tank. Notice: Your cooling system pressure cap is a pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. Your Driver Information Center (DIC) will also display messages about engine overheating. See Engine Coolant Temperature Gage on page 3-38.

Overheated Engine Protection Operating Mode If an overheated engine condition exists and the message HOT STOP ENGINE is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided. Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system. See “Engine Oil” in the Index.

If Steam Is Coming From Your Engine

Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See “Overheated Engine Protection Operating Mode” in the Index for information on driving to a safe place in an emergency.

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. See “Overheated Engine Protection Operating Mode” in the Index for information on driving to a safe place in an emergency.

5-29

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 and you have not stopped, pull over, stop, and park your vehicle right away. If there’s still no sign of steam, you can idle the engine for three minutes while you’re parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” listed previously in this section. You may decide not to lift the hood but to get service help right away.

If No Steam Is Coming From Your Engine An overheat warning, along with a low coolant message, can indicate a serious problem. See “Low Coolant Message” under DIC Warnings and Messages on page 3-50. If you get an engine overheat warning with no low coolant message, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:

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

If you get the overheat warning with no sign of steam, try this for a minute or so:

1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle.

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

speed and open the window as necessary.

5-30

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

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

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

5-31

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.

A low coolant level should be indicated by a LOW ENGINE COOLANT message on the Driver Information Center. If it is, 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.

5-32

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, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service. Notice: Engine damage from running your engine without coolant isn’t covered by your warranty. See “Overheated Engine Protection Operating Mode’’ in the Index for information on driving to a safe place in an emergency.

Notice: When adding coolant, it is important that you use only DEX-COOL@ (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner - at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOL@ is not covered by your new vehicle warranty. How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level isn’t at or above the FULL COLD fill mark line (4.5 inches (1 1 cm) from the top of the filler neck), add a 50/50 mixture of clean, drinkable water and DEX-COOL@ coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank A n it Cnn Enn;nn n r m n n l ~ v n rr-n pIcIaauIcI uuy, I d vvvl U c I I U I b y v u uv I L .

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

5-33

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 COOL@ coolant.

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 IT-:-’=- e.

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.

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.

1. Park the vehicle on a level surface. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one-quarter turn and tnen stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

2. Then keep turning the

pressure cap slowly, and remove it.

3. Then fill the coolant surge tank with the proper mixture, to the FULL COLD fill mark line (4.5 inches (1 1 cm) from the top of the filler neck).

5-35

5. Then replace the pressure cap. Be sure the arrow

on the pressure cap lines up like this.

4. With the coolant surge tank pressure cap off, start

the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches about 4.5 inches (1 1 cm) from the top of the filler neck.

Power Steering Fluid

The power steering fluid reservoir is near the center of the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-14 for more information on 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 !eve! on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. What to Use To determine what kind of fluid to use, see Part D: Recommended Fluids and Lubricants on page 6-15. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.

5-37

Notice:

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

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 on page 5-14 for reservoir location. Adding Washer Fluid

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

Brakes Brake Fluid

A DOT3

Your master cylinder reservoir is on the driver’s side of the engine compartment. It is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 5-14 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 don - I n the brake hydraulic sys’- -n

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.

When your brake fluid falls to a low level, your brake warning light will come on. A chime will sound if you try to drive with this warning light on. See Brake System Warning Light on page 3-35.

5-39

What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to Part D: Recommended Fluids and Lubricants on page 6-75. 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 enteri-- the reservoir.

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

Notice:

Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

5-40

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

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

Notices 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 on page 6- 14. 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 apply the brakes, with or without the vehicle moving, your brakes adjust for wear.

- - ~ t t e r y - . ~ t sulfuric acid fumes into the area under the rear seat cushion. These fumes can damage your rear seat safety belt systems. You may not be able to see this damage, and the safety belts might not provide the protection needed in a crash. If a replacement battery is ever needed, it must be vented in the same manner as the original battery. Always make sure that the vent hose is properly reattached before reinstalling the seat cushion.

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 ACDelco@ battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. 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.

5-42

To be sure the vent hose (A) is properly attached, the vent hose connectors (B) must be securely reattached to the vent outlets (C) on each side of the battery, and the vent assembly grommet (D) must be secured to the floor pan (E).

Vehicle Storage If you’re not going to drive you vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your-battery from running down.

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” next 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 on page 3-73.

5-43

Jump Starting

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

t safely.

Batteries can hurt you. They can be d gerous because:

They contain acid that can burn you. They contain gas that can explode or ignite. They contain enough electricity to burn you.

If you don’t follow these steps exactly, 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. 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.

5-44

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

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

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

4. Open the hood on the other vehicle and locate the positive (+) and the negative (-) terminal locations on that vehicle. Open the hood on your vehicle and find the remote positive (+) terminal located in the engine compartment on the passenger side of the vehicle. 5. To access the remote

positive (+) terminal, remove the cover.

You will not see the battery of your vehicle under the hood. It is located under the rear passenger seat. You will not need to access the battery for jump starting. The remote positive (+) terminal is for that purpose.

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

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 ACDelco@ battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

6. 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.

5-46

7. Connect the red

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

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

9. 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 doesn’t go to the dead battery. It goes to a heavy, metal engine part or to a remote negative (-) terminal

unpainted

the vehicle with the dead battery.

5-47

10. 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.

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

the engine for a while.

12. Try to start the vehicle that had the dead battery. If

it won’t start after a few tries, it probably needs service.

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

The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less. Use a remote negative (-) terminal if the vehicle has one. Your vehicle has a remote negative (-) terminal marked “G N D .”

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.

5. Return the positive (+) remote terminal cover to its

Headlamp Aiming

Your vehicle has a visual optical headlamp aiming system equipped with horizontal aim indicators. The aim has been preset at the factory and should need no further adjustment. This is true even though your horizontal aim indicators may not fall exactly on the “ 0 (zero) marks on their scales. If your vehicle is damaged in an accident, the headlamp aim may be affected. Aim adjustment to the low beam may be necessary if it is difficult to see lane markers (for horizontal aim), or if oncoming drivers flash their high beams at you (for vertical aim). If you believe your headlamps need to be re-aimed, we recommend that you take your vehicle to your dealer for service. However, it is possible for you to re-aim your headlamps as described in the following procedure.

5-50

Notice: To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts. The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall or other flat surface. The vehicle must have all four tires on a perfectly level surface which is level all the way to the wall or other flat surface. The vehicle should be placed so it is perpendicular to the wall or other flat surface. The vehicle should not have any snow, attached to it. The vehicle should be fully assembled and all other work stopped while headlamp aiming is being done. The vehicle should be normally loaded with a full tank of fuel and one person or 160 Ibs (75 kg) on the driver’s seat. Tires should be properly inflated.

4. Turn on the low-beam headlamps and place a piece of cardboard or equivalent in front of the headlamp not being aimed. This should allow only the beam of light from the headlamp being aimed to be seen on the flat surface.

Notice: Do not cover a headlamp to improve beam cut-off when aiming. Covering a headlamp may cause excessive heat build-up which may cause damage to the headlamp.

Turn the vertical aiming screw (C) until the headlamp beam is aimed to the horizontal tape line.

The top edge of the cut-off should be positioned at the bottom edge of the horizontal tape line.

Lift the wiper up from the windshield and set it

into the vertically-locked position.

2. Push the tab on the wiper blade assembly and pull

the assembly down enough to release it from the “U” hooked end of the wiper arm. Slide the assembly away from the arm.

3. Remove the blade. 4. To reinstall the wiper blade assembly, slide it over

the wiper arm to engage the “U” hooked end on the wiper blade assembly. Pull up on the assembly to lock it into place.

For the proper windshield wiper blade assembly replacement length and type, see Normal Maintenance Replacement Pan‘s on page 5- 101.

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 Oldsmobile Warranty booklet for details.

Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold.

CAUTION:

Overinflated tires are more lik to be cut, punctured or broken by a sudden impact - such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

Inflation -- Tire Pressure

The Tire-Loading Information label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).

Notice: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: 0 Too much flexing

Too much heat Tire overloading Bad wear

0 Bad handling

Bad fuel economy

If your tires have too much air (overinflation), you can get the following:

Unusual wear Bad handling

0 Rough ride

Needless damage from road hazards

When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 kPa). woav 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.

Check Tire Pressure System The check tire pressure system can alert you to a large change in the pressure of one tire. The system won’t alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The LOW TIRE PRESSURE message will appear on the Driver Information Center (DIC) if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if:

more than one tire is low, the vehicle is moving faster than 65 mph (105 km/h), the system is not yet calibrated, the tire treadwear is uneven, the compact spare tire is installed, tire chains are being used, or the vehicle is being driven on a rough or frozen road.

If the anti-lock brake system warning light comes on, the check tire pressure system may not be working properly. See your dealer for service. Also, see Anti-Lock Brake System Warning Light on page 3-36. The check tire pressure system detects differences in tire rotation speeds that are caused by changes in tire pressure. The system can alert you about a low tire - but it doesn’t replace normal tire maintenance. See Tires on page 5-60. When the LOW TIRE PRESSURE message appears on the Driver Information Center, you should stop as soon as you can and check all your tires for damage. If a tire is flat, see If a Tire Goes Flat on page 5-70. Also check the tire pressure in all four tires as soon as you can. See Inflation -- Tire Pressure on page 5-60. Any time you adjust a tire’s pressure or have one or more tires repaired or replaced, you’ll need to reset (calibrate) the check tire pressure system. You’ll also need to reset the system whenever you rotate the tires, buy new tires and install or remove the compact spare. Don’t reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire pressure system will not work properly and may not alert you when a tire is low or high.

To reset (calibrate) the system: 1. Turn the ignition switch to ON. 2. Press the SELECT right arrow on

the DIC until you

enter the GAGE mode. Then press the SELECT down arrow until TIRE PRESSURE appears on the display.

3. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show TIRE PRESSURE RESET. If TIRE
