1996 Oldsmobile Aurora Owners Manual

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.

NOTICE:

When adding coolant it is important that you use DEX-COOL TM (orange-colored, silicate-free) coolant meeting GM Specification 6277M. If silicated coolant 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.

What to Use Use a mixture of one-half cEean, water (preferably distilled) and one-half DEX-COOL TM (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. A special procedure is required for adding sealer; see the Aurora Service Manual. (To order a service manual, see “Service Publications’’ in the Index.)

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 (orange-colored, silicate-free) antifreeze.

NOTICE:

If you us& 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 times a year, have your retailer check your cooling system.

I 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

When your engine is cold, the coolant level should be at the FULL COLD mark or a little higher.

The engine coolant surge tank is located on the driver's

side of the engine compartment. - A CAUTION:

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. 6-22

If the message LOW ENGINE COOLANT is displayed on your message center, it means you on engine coolant.

're low

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

When replacing the pressure cap, make sure it is tight. 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.

Adding Coolant If you need more coolant, add the proper mix at the surge tank, but only when the engine is cool.

Power Steering Fluid When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

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. The level should be at the FU,L COLD mark. If necessary, add only enough fluid to bring the. level up to the mark.

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.

Adding Washer Fluid

There are two windshield washer fluid tanks. The upper tank (shown above) will empty first. When the lower tank contains 0.5 quarts (0.5 liters) or less, the message LOW WASHER FLUID will be displayed on the Driver Information Center.

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

NOTICE:

Brake- Brake Flr -’

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 3/4 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.

Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. There are only two reasor why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have

your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

I ’ A CAUTION:

If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.

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” in the Index.

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.

(GM Part

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.

Brake Wear Your Aurora 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 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.

I 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. Brake linings should always be replaced as complete axle sets. 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 Aurora 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.

Battery Every new Aurora 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. The battery is located under the rear seat cushion. To access the battery, see “Removing the Rear Seat Cushion” in the Index. You don’t need to access the battery to jump start your vehicle. See “Jump Starting” in the Index.

CAUTION:

A battery that isn’t properly vented can let 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.

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

I’

Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting’’ in the Index for tips on working around a battery without getting hurt.

Contact your retailer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature” in the Index.

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).

Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Take special care when handling and disposing of halogen bulbs.

Headlamps For the type of bulb, see “Replacement Bulbs” in the Index.

Low-Beam Bulbs 1. Remove the air cleaner cover to get to the driver’s

2. Now you can reach in behind the lamp housing and

pull out the bulb.

3. To replace the bulb, angle the new bulb into the

empty socket.

4. Push the base of the bulb down to lock it into place.

Headlamp Aiming Your vehicle has the composite headlamp system. These headlamps have horizontal and vertical aim indicators. The aim has been pre-set at the factory and should need no further adjustment. If your vehicle is damaged in an accident and the headlamp aim seems to be affected, see your Aurora retailer. Headlamps on damaged vehicles may require recalibration of the horizontal aim by your Aurora retailer. To check the aim, the vehicle should be properly prepared as follows:

The vehicle must have all four tires on a perfectly level surface.

0 The vehicle should not have any snow, ice, or mud

attached to it. There should not be any cargo or loading of vehicle, except it should have a full tank of gas and one person or 160 pounds (75 kg) on the driver’s seat. Tires should be properly inflated.

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.

State inspection stations will allow a vertical reading of plus 0.76 degrees or minus 0.76 degrees from the center of the bubble. It is recommended that the upper limit not exceed plus 0.4 degrees from the center of the bubble. Other drivers may flash their bright lights at you if your adjustment is much above plus 0.4 degrees. If you find that the headlamp aiming needs adjustment, follow these steps:

Start with the vertical headlamp aim. Don't try to adjust the horizontal aim first. Adjustment screws can be turned with an E8 Torx@socket or T15 Torx screwdriver.

1. Check the vertical aim for each headlamp and adjust it as necessary. Turn the vertical aiming screw until the bubble in the level is centered at 0 (zero).

2. Now adjust the horizontal aim. Check the horizontal

aim for each headlamp and adjust it as necessary. Turn the horizontal aiming screw until the pointer is lined up with the 0 (zero).

3. Now, re-check the vertical aim, to make sure it

is still correct after the horizontal aim adjustment. Readjust, if necessary.

Taillamps For the type of bulb, see "Replacement Bulbs" in the Index.

2.

Unscrew the convenience net attachment nut. Open the trim panel door.

1. In the trunk, remove the convenience net from the hooks. Next remove the plastic screws holding the carpeting in place and pull back the carpeting.

3.

Remove the two wing nuts now exposed.

4. Remove the taillamp filler screw located to the side

of the taillamp filler panel.

5. Pull out the lamp to reach the bulb. Pull out the bulb.

To replace, push the bulb back in.

6. Reverse Steps 1-5 to replace the taillamp filler, wing

nuts and carpeting.

Windaield Wiper Blade Replacement

Replacement blades come in different types and are removed in different ways. Here’s how to remove the type with a release hole: 1.

Pull the windshield wiper arm away from the- windshield. Insert a small screwdriver into the hole (A) and pull the blade assembly off the’wiper arrri (B). Push the new wiper blade securely’.on the wiper arm.

3. For the proper windshield wiper blade length and type, see “Normal Replacement Parts” in the Index.

Tires We don’t make tires. Your new Aurora 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 Aurora Warranty booklet for details.

6-40

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. 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 impact -- such as when you hit a pothole. cut, punctured or broken by a sudden 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 a mile.

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:

Too much flexing

0 Too much heat

Tire overloading Bad wear Bad handling Bad fuel economy.

NOTICE: (Continued)

NOTICE: (Continued)

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

Unusual wear 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 E a ) .

How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.

Tire Inspection and Rotation Tires should be 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 front and rear inflation pressures as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.

The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled rotation intervals.

6-42

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

. .~

When It’s Time for New Tires

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

You need a new tire if any of the following statements are true:

You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.

6-43

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

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 four 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. 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

6-45

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

wneels, which can sometimes be repaired). See your Aurora 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. 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 Aurora model.

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.

NOTICE:

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

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

Used Replacement Wheels

i ’ 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. replace a wheel, use a new GM original equipment wheel.

If you have to

Tire Chains

NOTICE:

Use tire chains only where legal and only when you must. Use only SAE Class ccS” 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 Aurora, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle:

Gasoline Benzene Naphtha

0 Carbon Tetrachloride

Acetone

0 Paint Thinner 0 Turpentine 0 Lacquer Thinner 0 Nail Polish Remover They can all be hazardous -- some more than others -- and they can all damage your vehicle, too.

6-48

Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle:

Alcohol

0 Laundry Soap 0 Bleach 0 Reducing Agents CIeaning the Inside of Your Aurora Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Aurora 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 the entire area immediately or it will set.

Using Foam-Type Cleaner on Fabric

Vacuum and brush the area to remove any loose dirt. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. Mix Multi-Purpose Powdered Cleaner following the directions on the container label. Use suds only and apply with a clean sponge. Don’t saturate the material. Don’t rub it roughly. As soon as you’ve cleaned the section, use a sponge to remove the suds. Rinse the section with a clean, wet sponge. Wipe off what’s left with a slightly damp paper towel or cloth. Then dry it immediately with a blow dryer. Wipe with a clean cloth.

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.

6-49

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:

Carefully scrape off excess stain. Follow the solvent-type instructions described earlier. 0 Shoe polish, wax crayon, tar and asphalt will stain

if left on a vehicle’s seat fabric. They should be removed as soon as possible. Be careful, because the cleaner will dissolve them and may cause them to spread.

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: 0 Carefully scrape off excess stain, then sponge the

soiled area with cool water. If a stain remains, follow the foam-type instructions described earlier.

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

0 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.

0 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. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a GM Vinylbeather 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 Vinylbeather 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 Panel 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 Wood Panels Use a clean cloth moistened in warm, soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth.

Care of Safety Belts Keep belts clean and dry.

Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash they might not be able to provide adequate protection. Clean safety belts 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 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. 1050011). The windshield is clean if beads do not form when you rinse it with water. 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 Aurora 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. High pressure car washes may cause water to enter your vehicle.

Finish Care Occasional waxing or mild polishing of your Aurora 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 Aurora has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. fdways use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish.

NOTICE:

Machine compounding or aggressive polishing on a basecoat/clearcoat 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 looking new by keeping your Aurora garaged or covered whenever possible. Aluminum or Chrome Wheels 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 wash 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.

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.

Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to the parts repaired or replaced to restore, corrosion protection. Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your retailer or other service

6-54

outlets. Larger areas of finish damage can be corrected in your retailer’s body and paint shop. 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. 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.

your VIN, the model designation, paint information, and

0 a list of all production options and special

equipment.

Be sure that this label is not removed from the vehicle.

This is the legal identifier for your Aurora. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration. Engine Identification The eighth character in your VIN is the engine code. This code will help you identify your engine, specifications, and replacement parts.

Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker and a fuse in the fuse panel on the other side of the instrument panel. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed. Power Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed.

Electrical System Add-on Electrical Equipment

I NOTICE:

Don’t add anything electrical to your Aurora unless you check with your retailer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should.

Your vehicle has an air bag system. Before attempting to add anything electrical to your Aurora, see “Servicing Your Air Bag-Equipped Aurora’’ in the Index. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the wiring harness. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp system checked right away.

Maxifuse/Relay Center

It’s easy to check the fuses in this underhood relay center. There are two locking m s on either side of the base of the cover. Reach down and unsnap each one by pulling the cover toward you, then pushing it away while pulling up. Remove the cover. The inside of the cover has a chart that explains the features and controls governed by each fuse and relay.

Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the correct amp rating. Two spare fuses are located below the fuse puller. You’ll also find spare fuses in the slots labeled “Spare” in the following charts. There are three main fuse panels: the instrument panel fuse block and two (driver’s side and passenger’s side) rear compartment fuse blocks.

Instrument Panel Fuse Block This is located on the left side of the instrument panel. To open it, push the latch to the left, then pull, and the door will open. You’ll find a fuse puller clipped to the inside of the cover. Place the wide end of the fuse puller over the plastic end of the fuse. Squeeze the ends over the fuse and pull it out. To close the fuse door, press the door closed and it will latch.

Removing the Rear Seat Cushion To access the battery and rear compartment fuse panels, the rear seat cushion must be removed. This procedure is somewhat difficult. You may wish to have your retailer do this for you.

I NOTICE:

The battery and main fuse boxes are located under the rear seat cushion. The battery’s ground terminal and some relay wires are exposed. To help avoid damage to the battery and wires, be careful when removing or reinstalling the seat cushion. Do not remove covers from covered parts. Do not store anything under the seat, as objects could touch exposed wires and cause a short.

To Remove the Rear Seat Cushion 1. Pull up on the front of the cushion to release the

front hooks.

2. Pull the cushion up and out toward the front of the

vehicle.

To Reinstall the Rear Seat Cushion

I passenger. The person sitting in that position

could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not

twisted.

4.

Buckle the center passenger position safety belt, and then route the safety belts through the proper slots in the seat cushion. Don’t let the safety belt get twisted. Slide the rear of the cushion up and under the seatback so the rear locating guides hook into the wire loops on the back frame. With the seat cushion lowered, push rearward and then press down on the seat cushion until the spring locks on both ends engage. Check to make sure the safety belts are properly routed and that no portion of any safety belt is trapped under the seat. Also. make sure the seat cushion is secured.

6-61

A safety belt that isn’t properly routed through the seat cushion or is twisted won’t provide the protection needed in a crash. If the safety belt hasn’t been routed through the seat cushion at all, it won’t be there to work for the next

CAUTION: (Continued)

Rear Compartment Fuse Blocks

Once the seat is removed, you’ll find two fuse panels on the driver’s side of the battery. Each is protected by a plastic box with four tabs. Pull up on all four tabs at the same time to loosen them and pull off the box.

Of these two panels, the cover on the passenger’s side fuse panel has an extra plastic cap attachment. You’ll need to slide this out of the grooves which hold it there before removing the rest of the box. To replace the covers, line the four tabs up and simply snap them back into place. The extra plastic cap attachment slides back into place.

This section covers the maintenance required for your Aurora. Your vehicle needs these services to retain its safety, dependability and emission control performance.

n Protection

Have you purchased th.e GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet, 01- your Aurora retailer for details.

Introduction Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, please maintain your vehicle properly.

How This Section is Organized The remainder of this section is divided into five parts: “Part A: Scheduled Maintenance Services” shows what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your retailer’s service department or another qualified service center do these jobs.

Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, have a qualified technician do the work.

If you are skilled enough to do some work on your vehicle, you will probably want to get the service information GM publishes. See “Service and Owner Publications” in the Index.

7-2

“Part B: Owner Checks and Services” tells you what should be checked whenever you stop for fuel. It also explains what you can easily do to help keep your vehicle in good condition. “Part C : Periodic Maintenance Inspections’’ explains important inspections that your Aurora retailer’s service department or another qualified service center should perform. “Part D: Recommended Fluids and Lubricants” lists some products GM recommends to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” provides a place for you to record the maintenance performed on your vehicle. Whenever any maintenance is performed, be sure to write it down in this part. This will help you determine when your next maintenance should be done. In addition, it is a good idea to keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their GM vehicles, maintenance needs vary. You may even need more frequent checks and replacements than you’ll find in the schedules in this section. So please read this section and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your Aurora retailer.

This part tells you the maintenance services you should have done and when you should schedule them. If you go to your retailer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts. The proper fluids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. These schedules are for vehicles that: 0 carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Tire-Loading Information label. See “Loading Your Vehicle’’ in the Index.

0 are driven on reasonable road surfaces within legal

driving limits. use the recommended fuel. See “Fuel” in the Index.

Selecting the Right Schedule First you’ll need to decide which of the two schedules is right for your vehicle. Here’s how to decide which schedule to follow:

Maintenance Schedule

Short Trip/City Definition Follow the Short Trip/City Maintenance Schedule if any one of these conditions is true for your vehicle:

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. If the vehicle is used for delivery service, police, taxi, or other commercial application.

One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down S O O I Z ~ C

These intervals only summarize maintenance services. Be sure to follow the complete maintenance schedule on the following pages.

Short Trip/City Maintenance Schedule

The services shown in this schedule up to 100,000 miles (166 000 km) should be performed after 100,000 miles (166 000 km) at the same intervals. Footnotes 3‘ The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

* Your vehicle has an Engine Oil Life Monitor. This monitor will show you when to change the oil -- usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 7,500 miles (12 500 km) or 12 months without an oil change. The system won’t detect dust in the oil. So if you drive in a dusty area be sure to change your oil every 3,000 miles (5 000 km) or sooner if the CHANGE OIL light comes on. Remember to reset the Oil Life Monitor when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index.
