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

I NOTICE:

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

Compact Spare Tire Although the compact spare 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: Don’t take your compact spare through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.

5-29

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 fdst. The method known as “rocking” can help you get out when you’re stuck, but you must use caution.

I 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. You should turn your traction control system off. (See ”Traction Control System” in the Index.) 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 Aurora. 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 Aurora 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 Aurora Service Manual. It tells you much more about how to service your Aurora than this manual can. To order the proper service manual, see “Service Publications’‘ in the Index.

6-1

Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Aurora” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

6-2

I NOTICE:

If you try to do your own service work without knowing enough about it, your vehicle could be damaged.

Fuel Use premium unleaded gasoline rated at 91 octane or higher. It should meet specifications ASTM D48 14 in the United States and CGSB 3.5-92 in Canada. These fuels should have the proper additives, so you should not have to add anything to the fuel. In the United States and Canada, it’s easy to be sure you get the right kind of gasoline (unleaded). You’ll see UNLEADED right on the pump. And only unleaded nozzles will fit into your vehicle’s filler neck. Be sure the posted octane is at least 91. If the octane is less than 91, you may get a heavy knocking noise when you drive. (In an emergency, you may be able to use lower octane -- as low as 87 -- if heavy knocking does not occur.) If you’re using 91 or higher octane unleaded gas and you still get heavy knocking, your engine needs service.

What about gasoline with blending materials that contain oxygen (oxygenates), such as MTBE or alcohol‘? MTRE is “methyl tertiary-butyl ether.” Fuel that is no more than 15% MTBE is fine for your vehicle. Ethcrnol is ethyl or grain alcohol. Properly-blended fuel that is no more than 10% e r h d is fine for your vehicle. Metlmzol is methyl or wood alcohol.

NOTICE: Fuel that is more than 5% methanol is bad for your vehicle. 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. And even at 5% or less, there must be “cosolvents” and corrosion preventers in this fuel to help avoid these problems.

Gasolines for Cleaner Air Your use of gasoline with deposit control additives will help prevent deposits from forming in your engine and fuel system. That helps keep your engine in tune and your emission control system working properly. It’s good for your vehicle, and you’ll be doing your part for cleaner air. Many gasolines are now blended with oxygenates. General Motors recommends that you use gasolines with these blending materials, such as MTBE and ethanol. By doing so, you can help clean the air, especially in those parts of the country that have high carbon monoxide levels. In addition, some gasoline suppliers are now producing reformulated gasolines. These gasolines are specially designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By doing so, you can help clean the air, especially in those parts of the country that have high ozone levels. You should ask your service station operators if their L. zasolines contain deposit control additives and oxygenates, and if they have been reformulated to reduce vehicle emissions.

Remote Fuel Door Release The remote fuel door release can help keep your fuel tank from being siphoned. Always be sure the fuel door is closed and latched after refueling.

To open the fuel door (on the left of the vehicle), press the button next to the trunk release button, to the right of the steering column. The ignition need not be on. The remote fuel door release will work in all transaxle positions.

Fuels in Foreign Countries If you plan on driving in another country outside the U.S. or Canada, unleaded fuel may be hard to find. Do not use leaded gasoline. If you use even one tankful, your emission controls won't work well or at a l l . With continuous use, spark plugs can get fouled, the exhaust system can corrode, and your engine oil can deteriorate quickly. Your vehicle's oxygen sensor will be damaged. All of that means costly repairs that 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 LIS where you're going and give your Vehicle Identification Number (VIN).

Harmonic Balancer Engine Oil If the CHECK 01L LEVEL message or the oil warning light on the instrument panel comes on, it means you need to check your engine oil level right away. For more information, see “Check Oil Level Message” or “Oil Warning 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. 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.

To Check 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 line. 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 upper mark that shows the proper operating range, your engine could be damaged.

Just fill it enough t o put the level somewhere in the proper operating range. Push the dipstick all the way back i n when you‘re through.

6-11

What Kind of Oil to Use Oils of the proper quality for your vehicle can be identified by looking for the ‘bStarburst” symbol. The “Starburst” symbol indicates that the oil has been certified by the American Petroleum Institute (API), and is preferred for use i n your gasoline engine.

LOOK

FOR MIS 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:

6-12

I-.

SAE lunl-30 PREFERRED

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED

As shown in the chart, SAE 10W-30 is best for your vehicle. However, you can use SAE SW-30 if it’s going to be colder than 60°F (16°C) before your next oil change. When it‘s very cold. you should use SAE SW-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such X SAE 2OW-SO.

NOTICE: Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines “Starburst” symbol. Failure to use the proper oil can result in engine damage not covered by your warranty.

GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the requirements for your vehicle. Engine Oil Additives Don’t add anything to your oil. Your Aurora retailer is ready t o advise if you think something should be added.

When to Change Engine Oil See if any one of these is true for you: 0 Most trips are less than 5 to I0 miles (8 to 16 km).

This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving i n stop and go traffic). Most trips are through dusty areas.

0 You frequently tow a trailer or use a carrier on top of

your vehicle.

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 k m ) or 3 months -- whichever comes first. (See “Change Oil Message” in the Index.) If the CHANGE OIL NOW message appears i n the Driver Information Center, you should change your oil. If none of them is true, change the oil and filter every 7,500 miles ( 12 SO0 km) or 12 months -- whichever colnes first. (See “Change Oil Message’‘ in the Index.) Always reset the engine oil life to 100% after every oil change.

Engine Coolant Heater An engine coolant heater can be a big help if you have to park outside in very cold weather, 0°F (- 18°C) or colder. If your vehicle has this option, see “Engine Coolant Heater” in the Index. 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 a l l 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.

Air Cleaner To Check or Replace the Air Filter

1 . Remove hose (A) from resonator channel. 2. Release tension of the wing screw clamp (B) on the

air intake duct where it attaches to the air cleaner cover near the top of the engine. Just turn the wing screw counterclockwise, then detach the duct from the air cleaner cover.

3. Push the duct and resonator assembly (C) rearward

and up, and hold out of the way.

4. There's a temperature sensor on the corner of the air

cleaner cover. Use a screwdriver to release the sensor's electrical connector retainer, and pull up.

5. Unsnap the two clamps by pushing down on the top of the air cleaner cover and pushing i n on the clamps toward the center of the cover. Then remove the cover.

A. Remove the air filter. 7. Install the new air filter and reverse all steps to

reinstall the cover. electrical wires, duct and clamp. Be sure the tabs of the air cleaner cover fit into the slots of the air cleaner housing. Then make sure both clamps are f ~ ~ l l y

engaged.

6- 15

Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.

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.

6-16

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. Refer to the Maintenance Schedule to determine when to change your fluid. See “Scheduled Maintenance Services” in the Index. How to Check Because this operation can be a little difficult, you may choose to have this done at your Aurora Retail Facility Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

NOTICE: Too much or too little fluid can damage your transaxle. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading transaxle fluid.

if you check your

Wait at least 30 minutes before checking the transaxle fluid level if you have been driving: 0 When outside temperatures are above 90°F (32°C). 0 At high speed for quite a while.

In heavy traffic -- especially in hot weather.

0 While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93 "C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it's colder than 50°F (lO"C), you may have to drive longer.

To check the fluid level

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

0 With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P).

0 Let the engine run at idle for three to five minutes. Then, without shutting off the engine, follow these steps:

1. Pull out the dipstick and wipe it with a clean rag or

paper towel.

2. Push it back in all the way, wait three seconds and

then pull it back out again.

6-17

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

level. The tluid 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.

How to Add Fluid 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 (OSL). DOIZ ’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. After adding fluid, recheck the fluid level as described under “HOW to Check.’’

0 When the correct fluid level is obtained, push the

dipstick back i n all the way.

and refill. Use GM Engine Coolant Supplement (sealer) with any cotnplete coolant flush and refill. If you use this mixture, you don‘t need to add anything else. A special procedure is required for adding sealer; see the A L I ~ o ~ ~ ”Service Publications“ in the Index.)

Service Manual. (To order a service 1nanual. see

Engine Coolant The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. The proper coolant for your Aurora will: 0 Give freezing protection down to -34°F (-37°C) 0 Give boiling protection up to 262°F (128°C). 0 Protect against rust and corrosion. 0 Help keep the proper engine temperature. 0 Let the warning lights work as they should. What to Use Use a mixture of one-half c.lt.crr~ wwtor (preferably distilled) and one-half antifreeze that meets “GM Specification 182S-M,” which won‘t damage aluminum parts. You call also use a recycled coolant conforming to GM Specification 1825-M with a complete coolant tlush

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.

Adding Coolant

The engine coolant surge tank is located on the driver’s side of the engine compartment.

To Check Coolant

When your engine is cold, the coolant level should be at the FULL COLD mark or a little higher. If the message LOW ENGINE COOLANT is displayed on your message center, it means you’re low on engine coolant.

6-20

Power Steering Fluid 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 FULL COLD mark. Add enough fluid to bring the level up to the mark. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

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

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.

6-21

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

NOTICE: When adding power steering fluid or making a complete fluid change, 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 t o 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.

6-22

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. To Add Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is f~111.

Brakes Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid.

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 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.

There are only two reasons why the brake fluid level i n your master cylinder 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

6-23

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

I NOTICE:

Don’t let someone put in the wrong kind of fluid. 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. Brake fluid can damage paint, so be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

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.

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.

6-24

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).

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 a s 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 YOLI apply the brakes, with or without the vehicle moving, your brakes adjust for wear.

6-25

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.

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 i n 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.

6-26

To be sure the vent hose (A) is properly attached, the vent hose connectors (B) must be securely reattached to the vent outlets (C) on each side of the battery, and the vent assembly grommet (D) must be secured to the floor pan (E). Vehicle Storage If you're not going to drive 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.

Contact your retailer to learn how to prepare your vehicle for longer storage periods. Halogen Bulbs

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 hctory 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. The vehicle should not have any snow, ice, or mud attached to it.

0 There should not be any cargo or loading of vehicle,

except it should have a full tank of gas and one person or 160 Ibs. (75 kg) on the driver's seat. Tires should be properly inflated.

I 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 recolnmended 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 T1S TorxB screwdriver.

6-28

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 acl-just the horizontal aim. Check the horizontal

aim for each headlamp and adjust it as necessary. TLII-11 the horizontal aiming screw until the pointer is lined up with the 0 (zero).

Windshield Wiper Blade Replacement

Tires We don’t make tires. Your new vehicle comes with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new Aurora. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

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.

2. Insert a small screwdriver into the hole (A) and pull

the blade assembly off the wiper arm (B).

3. Push the new wiper blade securely on the wiper arm.

6-34

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.

Don’t let anyone tell you that underinflation overinflation is all right. It’s not. If your tires don’t have enough air (underinflation) you can get:

Too much flexing Too much heat Tire overloading Bad wear Bad handling Bad fuel economy.

NOTICE: (Continued)

6-35

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. 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.

NOTICE: (Continued) If your tires have too much air (overinflation), you can get:

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 kPa).

Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires -- which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture.

6-36

When rotating your tires, always use the correct rotation pattern shown here. Don't include the conlpact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures a s shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" in the Index.

Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Inforrnation label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) nu~nber 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 y o ~ ~ r 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 origiml tires.

tires have an all-season tread

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 ( I .6 trim) or less of tread remaining.

You need a new tire if:

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 fcbric. 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.

6-38

Treadwear j on The treadwear grade is a comparative rating base( the wear rate of the tire when tested under control led conditions on a specified government test course. For example, a tire gkded 150 would wear one and a half ( I 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 G. 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 (straight-ahead) traction tests and does not include cornering (turning) traction.

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.)

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. These grades are molded on the sidewalls of passenger car tires.

While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades. 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 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.

I 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.

6-41

Tire Chains

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 Aurora, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Nc)c)er* use these to clean your vehicle:

Gasoline Benzene Naphtha

0 Carbon Tetrachloride

Acetone

0 Paint Thinner 0 Turpentine 0 Lacquer Thinner

Nail Polish Remover

They can a l l be hazardous -- some no re than others -- and they can a l l damage your vehicle, too.

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

Alcohol Laundry Soap Bleach Reducing Agents

Cleaning 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: 0 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.

6-43

0 If a ring forms after spot cleaning, clean the entire

area immediately or it will set.

Using Foarn-']lSrpe Cleaner on Fabric

Vxuum 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 011 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 or a heat lamp.

NOTICE: I Be careful. A blow dryer may scorch the fabric.

0 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, dl111 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. (See the previous NOTICE.)

6-44

Special Cleaning Problems

Greasy or Oily Stains Such a s 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.

0 Follow the solvent-type instructions described

earlier. Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle 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 Such as catsup. coffee (black). egg. fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood.

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 watedbaking soda solution: 1 teaspoon ( 5 ml) of baking soda to 1 cup (250 m l ) of lukewarm water. 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. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a GM Vinyl/Leather Cleaner or equimlent product.

6-45

1 i I I I

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

Care of Safety Belts Keep belts clean and dry.

For stubborn stains, use a GM Vinylkeather 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.

6-46

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. 10500 I 1). 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" i n 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 liq~~id 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 vehicle 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. Always use waxes and polishes that are non-abrasive and made for a basecoatklearcoat paint finish.

1 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 looking new by keeping your Aurora garaged or covered whenever possible. Aluminum Wheels Your aluminum wheels have a protective coating similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, chrome polish, abrasive cleaners or abrasive cleaning brushes on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.

I NOTICE:

Don’t use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can take the protective coating off your aluminum wheels.

Tires To clean your tires, use a stiff brush with a tire cleaner. When applying a tire dressing always take care to wipe off any overspray or splash from painted surfaces. 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 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 comes first.

Add-on Electrical Equipment

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 A L ~ I - o ~ ~ , Your Air Bag-Equipped Aurora” in the Index.

see “Servicing

Removing the Rear Seat Cushion To access the battery and main fuse boxes, the rear seat cushion must be removed. You may wish to have your retailer do this for you.

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

1.

2.

3.

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.

6-53

4. 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.

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. There are three main fuse panels. Two are located under the rear seat. To access these panels, you’ll need to remove the seat. See the previous description under “Removing the Rear Seat Cushion” to see how. This procedure is somewhat difficult. You may wish to have your retailer replace the fuse, instead.

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-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.

6-54

Two spare fuses are located below the fuse puller. You’ll also find spare fuses in the slots labeled “Spare” on the following charts.

The third fuse panel is located on the left side of the instrument panel. To open it, simply pull on the latch 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.

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.

It’s easy to check the fuses in this underhood relay center. There are two locking arms 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.

Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the wiring harness. An electrical overload will cause the lamps t o go on and off, or in some cases to remain off. If this happens, have your headlamp system checked right away. Windshield Wipers 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.

@ Section 7 Maintenance Schedule

IMPORTANT: KEEP ENGINE OIL AT THE PROPER RECOMMENDED

.EVEL AND CHANGE AS

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 or the relnoval of important components can significantly affect the quality of the air we breathe. Improper fluid levels or even the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to help keep your vehicle in good condition, please lnaintain 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.

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 Publications” in the Index.

“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:

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. are driven on reasonable road surfaces within legal driving limits. use the recommended unleaded 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:
