1996 Oldsmobile Silhouette Owners Manual

To help avoid damage, install a towing dolly and raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment. Do not attach winch cables or J-hooks to suspension components when using car-carrier equipment. Always use T-hooks inserted in the T-hook slots.

5-9

Attach T-hook chains on both sides, in the slotted holes in the bottom of the frame rails behind the front wheels. These slots are to be used when loading and securing to car-carrier equipment.

Attach a separate safety chain around the outboard end of each control arm.

Rear 'low1 TOW Limits 55 mph (88 kwdh.) -- 500 miles (800 km)

/ / / / I

Attach T-hook chains on both sides, in the slotted holes in the frame rails, just ahead of the rear wheels. lnese slots are to be used when using sling type equipment or when loading and securing to car-carrier equipment.

Position the lower sling crossbar directly under the rear bumper.

Engir Overheating You will find a coolant temperature gage on your Oldsmobile’s instrument panel. See “Engine Coolant Temperature Gage” in the Index. You also have a low coolant level light on your instrument panel. See “Low Coolant Light” in the Index.

/11 CA JTILV:

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 opening 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.

I NOTICE: r ~

~~

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 the 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: 0 Climb a long hill on a hot day. 0 Stop after high-speed driving. 0 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. Turn off your air conditioner. 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 (@) or THLRD (D).

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

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, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, turn 08 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.

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

5-14

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

If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down.

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

5-15

A CAUTION:

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

How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at or above the FULL HOT mark, add a 501.50 mixture of den72 water (preferably distilled) and DEX-COOL TM (orange-colored, silicate-free) antifreeze at the coolant recovery tank. (See “Engine Coolant” in the Index for more information.)

NOTICE:

Engine damage from running your engine without coolant isn’t covered by your warranty.

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

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, 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 mix of clean water and DEX-COOL TM antifreeze.

5-16

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 mix.

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 or above the FULL HOT mark, start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mix directly to the radiator but be sure the cooling system is cool before you do it.

5-17

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator

pressure cap -- even a little -- they can come out

at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.

How to Add Coolant to the Radiator

2. Then keep turning the pressure cap, but now push

down as you turn it. Remove the pressure cap.

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

5-19

3. Fill the radiator with the proper mix, up to the base

of the filler neck.

4. Then fill the coolant recovery tank to the FULL

HOT mark.

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

leave the radiator pressure cap off.

5-20

6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fans.

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 mix through the filler neck until the level reaches the base of the filler neck.

8. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure the arrows on the pressure cap line up like this.

5-21

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. Air Inflator (Option) Your vehicle may have an air inflator used to bring tires up to the proper pressure. See “Air Inflator System” in the Index for more details. 5-22

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

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

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

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

Removing the Spare Tire and Tools The equipment you’ll need is in the storage compartment at the rear of the vehicle, on the passenger’s side.

Open the jack storage compartment by sliding the latch down and removing the compartment cover.

5-23

Remove the jack and jacking tools by loosening the wing nut and retainer bar. Separate the plastic pouch from the jack and remove the jacking tools (folding wrench and shaft) from the pouch.

The compact spare tire is located under the vehicle, behind the rear bumper. Insert the narrow end of the shaft into the hole above the rear bumper. Then attach the folding wrench to the shaft. Rotate the folding wrench counterclockwise to lower the compact spare tire until it can be pulled from under the vehicle.

Slide the cable retainer through the center of the spare, then place the compact spare tire near the flat tire.

The tools you'll be using include the jack (A), folding wrench (B) and shaft (C).

Spar -

1. Each wheel nut is covered with a nylon cap. Use the

folding wrench to remove the nylon caps from the wheel nuts before you loosen the nuts.

\ m

, ,-

I . , '

2. Loosen the wheel nuts -- but do not remove

them -- using the folding wrench.

3. Attach the folding wrench to the jack, and rotate the wrench clockwise to raise the jack head a few inches.

4. Near each wheel, there is a notch in the vehicle’s

frame. Position the jack and raise the jack head until it fits firmly into the notch in the vehicle’s frame (nearest the flat tire). Do not raise the vehicle yet. Put the compact spare tire near you.

5-27

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.

NOTICE:

Raising your vehicle with the jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack. Be sure to fit the jack lift head into the proper location before raising your vehicle.

‘

5. Raise the vehicle by rotating the folding wrench

clockwise in the -jack. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit.

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

7. Remove any rust or dirt

from the wheel bolts, mounting surfaces and spare wheel.

I A 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.

FTA TION:

8. Replace the wheel nuts with the rounded end of the

nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

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.

5-29

h

10. Tighten the wheel nuts

firmly in a crisscross sequence as shown.

9. Lower the vehicle by attaching the folding wrench to the jack and rotating the wrench counterclockwise. Lower the jack completely.

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.

Don’t try to put a wheel cover on the compact spare tire. It won’t fit.

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.

Storing a Flat or Spare Tire and Tools

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.

Lay the flat tire near the rear of the vehicle with the valve stem down. Slide the cable retainer through the center of the wheel and raise the flat tire until you hear the hoist mechanism click twice. This means that the wheel is firmly stored against the underside of the vehicle. When storing the spare tire, be certain to turn the spare so the valve stem is near the rear of the vehicle. This will help you to check and maintain tire pressure in the spare. Push against the tire to be certain

it is stored firmly.

5-31

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 posted speed limits for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.

NOTICE:

When the compact spare is installed, don’t take your vehicle through an automatic vehicle 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.

Replace all jacking tools as they were stored in the ’ storage compartment and replace the compartment cover. Be sure to also store the nylon nut caps. When you replace the compact spare tire with a full-size tire, replace the nylon nut caps over the wheel nuts. Tighten them “hand tight” using the folding wrench.

5-32

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

NOTICE:

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

If You’re Stuck: In Sand, Mud, Ice or Snow What you don’t want to do when your vehicle is stuck is to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution.

A CAUTION:

If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle 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 kmk) 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 transaxle back and forth, you can destroy your transaxle.

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 transaxle is in gear. 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.

Section 6 Service and Appearance Care

Here you will find information about the care of your Oldsmobile. This section begins with service and fuel information, and then it shows how to check important fluid and lubricant levels. There is also technical information about your vehicle, and a part devoted to its appearance care. Service Your Oldsmobile retailer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your retailer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks:

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Oldsmobile Service Manual. It tells you much more about how to service your Oldsmobile 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 Oldsmobile” 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.

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, and 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.

Fuel Use regular unleaded gasoline rated at 87 octane or higher. At a minimum, it should meet specifications ASTM D4814 in the United States and CGSB 3.S-M93 in Canada. Improved gasoline specifications have been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA 6-2

specification could provide improved driveability and emission control system protection compared to other gasolines. Be sure the posted octane is at least 87. If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine. If you’re using fuel rated at 87 octane or higher and you still hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. If your vehicle is certified to meet California Emission Standards (indicated on the underhood tune-up label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Oldsmobile retailer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty.

In Canada, some gasolines contain an octane-enhancing additive called MMT. If you use such fuels, your emission control system performance may deteriorate and the malfunction indicator lamp on your instrument panel may turn on. If this happens, return to your authorized Oldsmobile retailer for service. To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier.

NOTICE:

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

Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your 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. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

Filling Your Tank

‘ A CAUTION:

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

The cap is behind a hinged door on the driver’s side of your vehicle. You will notice that on the inside of the hinged door there is a place to hold the gas cap while you are adding fuel.

6-4

While refueling, hang the cap inside the fuel door. To take off the cap, turn it slowly to the left (counterclockwise).

’

If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and ’ wait for any WSS” 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 Oldsmobile” in the Index. When you put the cap back on, turn it to the right until you hear at least three clicks. Make sure you fully install the cap. The diagnostic system can deterrnine 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.

6-5

NOTICE:

If you need a new cap, be sure to get the right type. Your retailer can get one for you. If you get the wrong type, it may not fit or have proper venting, and your fuel tank and emissions system might be damaged.

Checkhg Things Under the Hood /I\ CAUTION:

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.

6-6

Hood Release

A CAUTION:,,

Things that burn can get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine.

To open the hood, first pull the hood release handle inside the vehicle.

Next, go to the front of the vehicle and pull up on the underhood release. Lift the hood.

The hood prop rod may be hot due to increased engine temperatures under the hood, so be careful when handling it. Use your hood prop sleeve when handling the hood prop.

Pull forward on the hood prop to release it from its storage clip. Put the end of the hood prop into the slot in the underside of the hood. Before closing the hood, be sure all the filler caps are on properly. Lift the hood to relieve the pressure on the hood prop. Remove the hood prop from the slot in the hood and return the prop to its retainer. Let the hood down and close it firmly. Underhood Lamp Your underhood lamp will go on when you open the hood. Engine Oil

LOW OIL

If the LOW OIL light on the instrument panel comes on, it means you need to check your engine oil level right away. For more information, see "LOW OIL Light" in the Index. You should check your engine oil level regularly; this is an added reminder.

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 at the front of the engine compartment, near the center. The dipstick handle has a bright, yellow loop design for easier identification. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level.

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

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

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.

6-10

The engine oil fill cap is located just behind the engine oil dipstick. Just 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.

What Kind of 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:

6-11

RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.

As shown in the chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 1OW-30 if it’s going to be 0” F (- 18 O C ) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 2OW-50.

When to Change Engine Oil See if any one of these is true for you:

Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). Most trips are through dusty areas. You frequently tow a trailer or use a carrier on top of your vehicle. The vehicle is used for delivery service, police, taxi or other commercial application.

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

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

A CAUTION:

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 off.

NOTICE:

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

The air cleaner is located at the front of the engine compartment (on the driver’s side of the vehicle), to the left of the windshield washer fluid reservoir. Refer to the Maintenance Schedule to determine when to replace the air filter and the crankcase ventilation filter. See “Scheduled Maintenance Services” in the Index.

6-14

Checking or Replacing the Air Cleaner

1. Loosen the four wing nuts. 2. Pull the top of the air cleaner toward the fro t of the

vehicle and remove the air cleaner filter. P

3. Be sure to install the air cleaner filter, replace the

cover and tighten the wing nuts securely.

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 krn) if the vehicle is mainly dnven under one or more of these conditions:

In heavy city traffic where the outside temperature regularly reaches 90 O F (3 2 O C) or higher.

0 In hilly or mountainous terrain. 0 When doing frequent trailer towing.

Uses such as found in taxi, police or delivery service.

If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing. See “Scheduled Maintenance Services” in the Index.

To get the right reading, the fluid should be at 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.

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 parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transaxle fluid.

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

1. The dipstick is located toward the back of the engine

compartment, near the center. The dipstick handle has a bright red loop design for easier identification. 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.

Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids and Lubricants” in the Index. 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 a pint (0.5 L). Don ’t overfill. We recommend you use only fluid labeled DEXRON@-111, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON-111 is not covered by your new vehicle warranty. 0 After adding fluid, recheck the fluid level as

described under “How to Check.” When the correct fluid level is obtained, push the dipstick back in all the way.

The cooling system in your vehicle is filled with new DEX-COOL TM (orange-colored, silicate-free) engine coolant. This coolant is designed to remain in your vehicle for 5 years or 100,000 miles (166 000 km), whichever occurs first. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. A 50/50 mixture of water and the proper coolant for your Oldsmobile will: 0 Give freezing protection down to -34°F (-37°C). 0 Give boiling protection up to 265°F (129°C).

Protect against rust and corrosion.

0 Help keep the proper engine temperature. 0 Let the warning lights and gages work as they should.

NOTICE:

when adding coolant it is important that you use DEX-COOL (orange-colored, silicate-free) coolant meeting GM Specification 6277M. If’silicated coolant is added to the system, premature engine, heater core or radiator coolant will require change sooner -- at corrosion may result. In addition, the engine 30,000 miles (50 000 km) or 24 months, whichever occurs first.

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL (orange-colored, silicate-free) antifreeze that meets GM Specification 6277M, which won’t damage aluminum parts. Use GM Engine Coolant Supplement (sealer) (GM Part No. 3634621) with any complete coolant change. If you use this mixture, you don’t need to add anything else.

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, 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 mix of clean water and DEX-COOL (orange-colored, silicate-free) antifreeze.

6-19

I I NOTICE:

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

If you have to add coolant more than four have your retailer check your cooling system.

times a year,

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 the The engine coolant reservoir is located on passenger’s side of the vehicle towards the middle of the engine compartment.

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

If this light comes on, it means you’re low on engine coolant.

LOW

Adding Coolant If you need more coolant, add the proper mix at the coolant recovery tank.

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.

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

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.

Radiator Pressure Cap

Power Steering Fluid

NOTICE:

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

When you replace your radiator pressure cap, an AC@ cap is recommended. Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. When you replace your thermostat, an AC@ thermostat is recommended.

6-22

The power steering fluid reservoir is located to the right of the engine coolant reservoir, at the back of the engine compartment.

When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How To Check Power Steering Fluid When the engine compartment is cool, 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. When the engine compartment is hot, the level should be at the H mark. When it’s cold, the level should be at the C mark. If the fluid is at the ADD mark, you should add fluid.

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

6-23

r F

Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full.

NOTICE:

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

The windshield washer fluid reservoir is located on the driver’s side of the vehicle, toward the front of the engine compartment.

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.

If you have too much brake fluid, 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.

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.

When your brake fluid falls to a low level, your brake warning light will come on. See “Brake System Warning

(GM Part

What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 No. 1052535). Use new brake fluid from a sealed container only, and always clean the brake fluid reservoir cap before removing it.

r With the wrong kind of fluid in your brake

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

6-26

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

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

NOTICE:

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

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Free movement of brake calipers and properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake calipers for movement, brake pads for wear, and evenly torque wheel nuts in the proper sequence to GM 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. 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 brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets.

6-27

Brake Pedal Travel See your retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear. Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your Oldsmobile does when it is new. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change -- for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts.

6-28

Battery Every new Oldsmobile has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label. Vehicle Storage for 25 days or more, If you’re not going to drive your vehicle take off the black, negative (-) cable from the battery. l h s will help keep your battery from running down.

I /II CAUTIPV:

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.

Tires We don’t make tires. Your new Oldsmobile 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.

/!1 CAUTION:

Poorly maintained and improperly used tires are dangerous.

Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index.

CAUTION: (Continued)

Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more likely to be cut, punctured or broken by a sudden

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

6-35

Inflation -- Tire Pressure

The CertificationlTire label, which is on the rear edge 01 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 0 Too much heat 0 Tire overloading 0 Bad wear 0 Bad handling 0 Bad fuel economy.

NOTICE: (Continued)

NOTICE: (Continued)

If your tires have too much air (overinflation). you can get the following: 0 Unusual wear 0 Bad handling 0 Rough ride 0 Needless damage from road hazards.

When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 Wa). How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.

6-36

Tire Inspection and Rotation Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km) for any signs of unusual wear. If unusual wear is present, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information.

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

The purpose of regular rotation is to achieTe 1yicsre uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” i n the Index for scheduled rotation intervals.

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

6-37

!n It’s

Vew Tires

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

You need a new tire if any of the following statements are true: 0 You can see the indicators at three or more places

around the tire.

0 You can see cord or fabric showing through the

tire’s rubber.

0 The tread or sidewall is cracked, cut or snagged deep

enough to show cord or fabric.

0 The tire has a bump, bulge or split. 0 The tire has a puncture, cut or other damage that

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

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

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

Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires.

While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to Federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.

Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction -- A, B, C The traction grades, from highest to lowest, are A, B, and C, and they represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

6-39

Warning: The traction grade assigned to this tire is based on braking (straightahead) traction tests and does not include cornering (turning) traction.

Temperature -- A, B, C

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

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

6-40

If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your Oldsmobile model.

NOTICE:

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

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

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

Used Replacement Wheels

A CAUTION,

~~

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

6-41

Tire Chains,

I NOTICE:

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

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

6-42

warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle:

Gasoline 0 Benzene 0 Naphtha 0 Carbon Tetrachloride

Acetone

0 Paint Thinner 0 Turpentine

Lacquer Thinner

0 Nail Polish Remover They can all be hazardous -- some more than others -- and they can all damage your vehicle, too. Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: 0 Alcohol 0 Laundry Soap 0 Bleach 0 Reducing Agents

Cleaning the Inside of Your Oldsmobile Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Oldsmobile retailer has two GM cleaners, a solvent-type spot lifter and a foam-type powdered cleaner. They will clean normal spots and stains very well. Do not use them on vinyl or leather. Here are some cleaning tips:

Always read the instructions on the cleaner label. Clean up stains as soon as you can -- before they set. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. Use solvent-type cleaners In a well-ventilated area only. If you use them, don’t saturate the stained area. If a ring forms after spot cleaning, clean area immediately or it will set.

Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent: 0 Gently scrape excess soil from the trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure and clean cloths (preferably cheesecloth). Cleaning should start at the outside of the stain, “feathering” toward the center. Keep changing to a clean section of the cloth.

0 When you clean a stain from fabric, immediately dry the area with a blow dryer to help prevent a cleaning ring.

Special Cleaning Problems Greasy or Oily Stains Stains caused by grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt can be removed as follows: I.

Non-Greasy Stains Stains caused by catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood can be removed as follows: 1. Carefully scrape off excess stain, then sponge the

soiled area with cool water.

2. If a stain remains, follow the foam-type instructions

described earlier.

3. If an odor lingers after cleaning vomit or urine, treat the area with a watedbaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water.

4. If needed, clean lightly with solvent-type cleaner. Combination Stains Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows:

Carefully scrape off excess stain, then clean with cool water and allow to dry. If a stain remains, clean it with solvent-type cleaner.

Cleaning Vinyl Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You may have to do it more than once.

0 Things like tar, asphalt and shoe polish will stain if

you don’t get them off quickly. Use a clean cloth and a GM Vinylkeather Cleaner or equivalent product.

Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap.

For stubborn stains, use a GM VinyULeather Cleaner or equivalent product. Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. Soiled leather should be cleaned immediately. If dirt is allowed to work into the finish, it can harm the leather.

Cleaning the Top of the Instrument Pal -1 Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.

Cleaning the Built-In Child Restraint Pad The built-in child restraint pad is attached to the seat frame with fastener strips. You can remove the pad and hand wash it with mild soap and water. Care of Safety Belts and Built-in Child Restraint Harness Keep the safety belts and the built-in child restraint harness clean and dry.

A CAUTION:

Do not bleach or dye safety belts or the built-in child restraint harness. If you do, they may be severely weakened. In a crash, they might not be able to provide adequate protection. Clean the safety belts and the child restraint harness only with mild soap and lukewarm water.

Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid. Cleaning the Outside of the Windshield, Backglass and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami Powder@ (GM Part No. 105001 1). The windshield is clean if beads do not form when you rinse it with water.

6-46

Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. (See “Recommended Fluids and Lubricants” in the Index.) Cleaning the Outside of Your Oldsmobile The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (mild detergent) soaps.

Don’t use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting. Before you enter an automatic car wash, if your vehicle is equipped with the optional power sliding door, be sure to have the ON/OFF switch in the OFF position. High pressure car washes may cause water to enter your vehicle. Finish Care Occasional waxing or mild polishing of your Oldsmobile by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your retailer. (See “Appearance Care and Materials” in the Index.) Your Oldsmobile has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish.

NOTICE:

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

Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish loohng new by keeping your Oldsmobile garaged or covered whenever possible.

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

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

I NOTICE:

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

Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Minor chips and scratches can be repaired with touch-up materials available from your retailer or other service outlets. Larger areas of finish damage can be corrected in your retailer’s body and paint shop.

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

Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your retailer or an underbody vehicle washing system can do this for you. Collision Repair Your vehicle was built with composite SMC (Sheet Molded Compound) fiberglass body panels and molded RIM (Reaction Injection Molded) front fenders and bumper covers. These panels require different collision repair procedures than metal-paneled vehicles. See your Oldsmobile retailer for information on collision repair.
