specified. Depending upon driving habits, the “Change Oil Soon’’ light may come on as early as 2,000 miles or less from the last time the oil life monitor was reset (See “Oil Life Monitor” in the Index.) Always reset the oil life monitor after every oil change. Engine Coolant Heater (Engine Block 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 all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Air Cleaner

The air cleaner is in the front right section of the engine compartment. To check or replace the filter, undo the wing screws and pull the air cleaner open. Replace the air filter, close the cover and tighten the wing screws.

243

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.

244

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 a Buick dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

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

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 "P" (Park).

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

I . Pull out the dipstick

and wipe it with a clean rag or paper towel.

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. 0 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.

0 With the parking brake applied, place the shift lever

in "P" (Park).

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

then pull it back out again.

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

level. The fluid level must be in the cross-hatched area.

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

dipstick back in all the way.

246

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. 2.

Pull out the dipstick. Using a long-neck funnel, add enough fluid at the dipstick hole to bring it to the proper 1evel.It doesn’t take much fluid, generally less than a pint (OSL). Don’t overfill. We recommend you use only fluid labeled DEXRON@-111 or DEXRON@-IIE, because fluids with that label are made especially for your automatic transaxle. Damage caused by fluid other than DEXRON@-I11 or DEXRON@-IIE is not covered by your new vehicle warranty. After adding fluid, recheck the fluid level as described under “How to Check.” When the correct fluid level is obtained, push the dipstick back in all the way.

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 Buick 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,

Let the warning lights work as they should.

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum parts. You can also use a recycled coolant conforming to GM Specification 1825-M with a complete coolant flush and refill. If you use this mixture, you don’t need to add anything else.

I NOTICE:

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

247

Adding Coolant

The coolant recovery tank is located at the left of the engine compartment.

To Check Coolant When your engine is cold, the coolant level should be at “FULL COLD’ or a little higher. When your engine is warm, the level should be up to “FULL HOT” or a little higher.

248

COOLANT

LOW

If this light comes on, it means you’re low on engine coolant. To Add Coolant If you need more coolant, add the proper mix at the coolant recovery tank.

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

Radiator Pressure Cap

Your radiator pressure cap is a 15 psi (1 05 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck.

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

249

0 When the engine compartment is cool, the level

should be at the “FULL COLD” mark.

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.

Power Steering Fluid

How To Check Power Steering Fluid 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 dimtick.

When the engine compartment is hot, the level should be at the “HOT” mark.

250

Windshield Washer Fluid To Add

Open the cap labeled “WASHER FLUID ONLY.” Add washer fluid until the bottle is full.

NOTICE:

~ ~

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only 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.

251

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

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.

There are only two reasons why the brake fluid level in 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

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.

252

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

NOTICE: 0 DOT-5 silicone brake fluid can damage

your vehicle. Don’t use it. 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.

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

253

1 Brake Adiustment - - __-- - - - -- tJ-----------

I Every time you apply the brakes moderately, 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 Buick 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.

I NOTICE: I 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. Your rear drum brakes don’t have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.

254

Battery Every new Buick 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 catalog number shown on the original battery’s label. 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 dealer to learn how to prepare your vehicle for longer storage periods. Halogen Bulbs

Headlamp Bulb Replacement

Remove the retainers by turning in a counter-clockwise direction.

Each headlamp is attached by retainers with round plastic knobs.

Lift the headlamp away from the car.

256

Turn the bulb socket 1/4 turn counter-clockwise, while pressing it firmly. Remove the wire connector from the bulb by lifting the lock tab and pulling it away from the plastic base.

Taillamp Bulb Replacement

Open the trunk. On either side of the rear of the trunk are two plastic nuts. Remove only the side that you need to access. Pull the carpet back away from the rear area. The taillamp, sidemarker and back-up lights can now be accessed.

To reassemble, attach the wire connector (A) to the plastic base making sure the lock tab (B) is over the lock (C). Install the bulb by putting the small tab (D) into the small notch in the lamp (E). Turn the bulb socket 1/4 turn clockwise to lock into place. When reinstalling the headlamp assembly into the headlamp mounting panel, make sure the tab is properly engaged in the panel slot.

Two labels on your vehicle show how much weight it may properly carry. The Tire Loading Information label found on the rear edge of the driver's door tells you the proper size, speed rating and recommended inflation pressures for the tires on your vehicle. It also gives you important information about the number of people that can be in your vehicle and the total weight that you can carry. This weight is called the Vehicle Capacity Weight and includes the weight of all occupants, cargo, and all nonfactory-installed options.

Two taillamp bulbs are a tabbed assembly. Squeeze the release in and pull the assembly out. Pull the bulb straight out from the socket. To replace the assembly, insert the tabs into the slots and push in until it locks into place. To replace the third taillamp bulb and sidemarker bulb, turn the socket 1/4 turn and pull it out. Pull the bulb straight out from the socket. The backup bulb can be replaced by squeezing the lock on the socket, turning it 1/4 turn and pulling it out. Pull the bulb straight out. Reverse the above steps to reassemble the light and the trunk trim.

The other label is the Certification label, found on the rear edge of the driver’s door. It tells you the gross weight capacity of your vehicle, called the GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle, or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. And, if you do have a heavy load, you should spread it out. Don’t carry more than 176 pounds (80 kilograms) in your trunk.

I NOTICE: I Your warranty does not cover parts or

components that fail because of overloading.

If you put things inside your vehicle -- like suitcases, tools, packages, or anything else -- they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they’ll keep going.

259

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 Buick. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

Inflation - Tire Pressure The Tire-Loading Information label which is located 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 &r overinflation is all right. It’s not. If your tires don’t have enough air (underinflation) you can get: 0 Too much flexing

Too much heat 0 Tire overloading

Bad wear

0 Bad handling

Bad fuel economy.

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

261

When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 Wa). How to Check Use a good quality pocket-type gage to check tire pressure. 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. Tire Inspection and Rotation To make your tires last longer, have them inspected and rotated at the mileages recommended in the Maintenance Schedule. See “Scheduled Maintenance Services” in the Index.

262

FRONT

Use this rotation pattern. After the tires have been rotated, adjust the front and rear inflation pressure as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” 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 2/32 inch (1.6 mm) or less of tread remaining.

You need a new tire if

three or more places

You can see the indicators at 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.

263

The tire has a puncture, cut, or other damage that can’t be repaired well because of the size or location of the damage.

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 a “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.

264

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.)

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. 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. 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.

265

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. 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 Buick dealer if any of these conditions exist. Your dealer 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 Buick model.

266

I NOTICE:

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

Used Replacement Wheels

Tire Chains

NOTICE: If your Buick has P215/70R15 size tires, don’t use tire chains; they can damage your vehicle. If you have other tires, 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 with chains on will damage your vehicle.

267

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 Buick, 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: 0 Gasoline Benzene Naphtha

0 Carbon Tetrachloride 0 Acetone

Paint Thinner Turpentine Lacquer Thinner Nail Polish Remover

They can all be hazardous -- some more than others -- and they can all damage your vehicle, too.

268

I NOTICE:

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

Laundry Soap Bleach Reducing Agents

Cleaning the Inside of Your Buick Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Buick dealer 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.

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

area immediately or it will set.

Using Foam-Type Cleaner on Fabric 0 Vacuum and brush the area to remove any loose dirt. 0 Always clean a whole trim panel or section. Mask

surrounding trim along stitch or welt lines.

0 Mix Multi-Purpose Powdered Cleaner following the

directions on the container label.

0 Use suds only and apply with a clean sponge. 0 Don’t saturate the material. 0 Don’t rub it roughly. 0 As soon as you’ve cleaned the section, use a sponge

to remove the suds.

0 Rinse the section with a clean, wet sponge. 0 Wipe off what’s left with a slightly damp paper towel

or cloth.

0 Then dry it immediately with a blow dryer or a heat

lamp.

I NOTICE: I Be careful with a hair dryer or heat lamp. You

could scorch the fabric.

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. When you clean a stain from fabric, immediately dry the area with an air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See the previous NOTICE.)

269

Special Cleaning Problems Greasy or Oily Stains Such as grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt. 0 Carefully scrape off excess stain.

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.

270

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. If needed, clean lightly with solvent-type cleaner.

Combination Stains Such as candy, ice cream, mayonnaise, chili sauce and unknown stains. 0 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 solvent-type vinyl cleaner.

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

0 For stubborn stains, use a mild solution of 10%

isopropyl alcohol (rubbing alcohol) and 90% water. 0 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 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 Speaker Covers Vacuum around a speaker cover gently, so that the speaker won’t be damaged. If something gets on one of them, follow the steps earlier under “Using Solvent-Type Cleaner on Fabric.” Use as little solvent as you can.

Care of Safety Belts Keep belts clean and dry.

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.

271

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 1 I ). 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. Cleaning the Outside of Your Buick 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 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 Buick may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See “Appearance Care and Materials’’ in the Index.)

Your Buick has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish.

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

Aluminum Wheels (If So Equipped) Your aluminum wheels have a protective coating similar to the painted surface of your car. 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.

1 NOTICE:

If you have aluminum wheels, don’t use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can take off the protective coating.

White Sidewall Tires Your Buick dealer has a GM White Sidewail %e Cleaner. You can use a stiff brush with the cleaner. 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 & Lubricants” in the Index.) 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.

Foreign Material Calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemica industrial chimneys, and other foreign matter can damage your vehicle’s finish if they remain on pa surfaces. Use cleaners that are marked safe for pa surfaces to remove foreign matter. 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 dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’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 dealer 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, Buick 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.

CODE

MODEL YEAR

IElll!l I 7 \ ASSEMBLY

PLANT

This is the legal identifier for your Buick. 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.

276

Service Parts Identification Label You’ll find this label on the spare tire cover. It’s very helpful if you ever need to order parts. On this label is:

your VIN, the model designation, paint information, and a list of all production options and special equipment.

Be sure that this label is not removed from the vehicle. Add-on Electrical Equipment

NOTICE: Don’t add anything electrical to your Buick unless you check with your dealer 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.

Remove the cover to access the fuses. To put the cover on, insert the tabs into the lower part of the fuse panel and snap it in place.

Your vehicle has an air bag system. Before attempting to add anything electrical to your Buick, see “Servicing Your Air Bag-Equipped Buick” in the Index. Fuses and Circuit Breakers The wiring circuits in your car are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself. The fuse panel is located under the instrument panel, next to the parking brake.

277

Headlights The headlight wiring is protected by a circuit breaker in the underhood fuse center. An electrical overload will cause the lights to go on and off, or in some cases to remain off. If this happens, have your headlight wiring checked right away. Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. 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 and not snow, etc., be sure to get 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 or goes away.

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 identical size and rating. There are additional fuses located behind the right sound insulator panel on the passenger side. If these require service, see your Buick dealer. Maxifuse/Relay Center To check the fuses in this underhood fuse center, turn the two knobs 1/4 turn counterclockwise and remove the cover. There is a chart inside the cover that explains the features and controls governed by each fuse and relay. The PASS-Key II@ fuse is located in the right side relay center.

Introduction A Word About Maintenance 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 will find in the schedules in this part. So please read this part and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your Buick dealer, the place many GM owners choose to have their maintenance work done. Your dealer can be relied upon to use proper parts and practices.

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 removal 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 maintain your vehicle properly. How This Part is Organized The remainder of this part is divided into five sections: “Section 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 dealer’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. You will find a list of publications and how to get them in this manual. See “Service Publications” in the Index.

“Section 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. “Section C: Periodic Maintenance Inspections” explains important inspections that your Buick dealer’s service department or another qualified service center should perform.

“Section 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. “Section 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 section. 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.

286

Section A: Scheduled Maintenance Services Using Your Maintenance Schedules This section tells you the maintenance services you should have done and when you should schedule them. Your Buick dealer knows your vehicle best and wants you to be happy with it. If you go to your dealer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts. 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:

Schedule I Is any one of these true for your vehicle?

Most trips are less than 4 miles (6 km).

0 Most trips are less than 10 miles ( 16 km) when

outside temperatures are below freezing.

0 The engine is at low speed most of the time (as in door-to-door delivery, or in stop-and-go traffic). You operate your vehicle in dusty areas. You tow a trailer. (With some models, you should never tow a trailer. See “Towing a Trailer” in the Index.)

If any one (or more) of these is true for your driving, follow Schedule I.

Schedule I1 Follow Schedule I1 only if none of the above conditions is true.

287

Scheduled Maintenance Services Schedule I

Follow Schedule I if your car is MAINLY driven under one or more of the following conditions:

~~~~

When most trips are less than 4 miles (6 kilometers). When most trips are less than 10 miles (16 kilometers) and outside temperatures remain below freezing. When most trips include extended idling and/or frequent low-speed operation as in stop-and-go traffic. Towing a trailer.*? When operating in dusty areas.

- -

Schedule I should also be followed if the car is used for delivery service, police, taxi or other commercial applications.

Explanation of Scheduled Maintenance Services Following are explanations of the services listed in Schedule I and Schedule 11. The proper fluids and lubricants to use are listed in Section 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. NOTE: To determine your engine’s displacement and code, see “Engine Identification” in the Index. 1. Engine Oil and Filter Change* -- Always use SH or SG Energy Conserving I1 oils of proper viscosity. The “SH” or “SG” designation may be shown alone or in combination with others, such as “SH/CD” or “SH, SG, CD,” “SG/CD,” etc. To determine the preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE low-30), see “Engine Oil” in the Index. If your vehicle has an Engine Oil Life Monitor, the monitor will show you when to change the oil. See “Engine Oil Life Monitor” in the Index.

2. Chassis Lubrication -- Lubricate the transaxle shift

linkage, parking brake cable guides, underbody contact points and linkage. If your vehicle is equipped with grease fittings, lubricate the suspension and steering linkage.

3. Tire and Wheel Rotation and Inspection -- For

proper wear and maximum tire life, rotate your tires following the instructions in this manual. See “Tires, Inspection & Rotation” in the Index. Check the tires for uneven wear or damage. If you see irregular or premature wear, check the wheel alignment. Check for damaged wheels also.

4. Engine Accessory Drive Belt(s) Inspection -- Inspect the belt(s) for cracks, fraying, wear and proper tension. Replace as needed.

5. Cooling System Service* -- Drain, flush and refill the system with new or approved recycled coolant conforming to GM Specification 1825M. Keep coolant at the proper mixture as specified. See “Coolant” in the Index. This provides proper freeze protection, corrosion inhibitor level and engine operating temperature.

292

Inspect hoses and replace if they are cracked, swollen or deteriorated. Tighten screw-type hose clamps. Clean the outside of the radiator and air conditioning condenser. Wash the pressure cap and neck. To help ensure proper operation, we recommend a pressure test of both the cooling system and the pressure cap.

6. Transaxle Service -- Change both the fluid and filter

every 15,000 miles (25 000 km) if the vehicle is mainly driven under one or more of these conditions:

In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher.

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

models, you shouldn’t ever tow a trailer. See “Towing a Trailer” in the Index.)

0 Uses such as found in taxi, police car or delivery

service.

If you do not use your vehicle under any of these conditions, change both the fluid and filter every 100,000 miles ( 160 000 km).

7. Spark Plug Replacement* -- Replace spark plugs with the proper type. See “Specifications Chart” in the Index.

8. Spark Plug Wire Inspection*-f -- Inspect for burns,

cracks or other damage. Check the boot fit at the distributor and at the spark plugs. Replace wires as needed.

9. Supercharger Oil Check--Check oil every 30,000

(50 000km) or 36 months. Check oil level only on cold engine. Add the proper synthetic oil. See “Recommended Fluids and Lubricants” in the Index. 10. Air Cleaner Filter Replacement* -- Replace every 30,000 miles (50 000 km) or more often under dusty conditions. Ask your dealer for the proper replacement intervals for your driving conditions.

1 1. Fuel Tank, Cap and Lines Inspection*? -- Inspect

fuel tank, cap and lines (including fuel rails and injection assembly) for damage or leaks. Inspect fuel cap gasket for an even filler neck imprint or any damage. Replace parts as needed. Periodic replacement of the fuel filter is not required.

* An Emission Control Service. -f 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 vehicle useful life. General Motors. however. urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”. 293

Section B: Owner Checks and Services Listed below are owner checks and services which should be performed at the intervals specified to help ensure the safety, dependability and emission control performance of your vehicle. Be sure any necessary repairs are completed at once. Whenever any fluids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Section D.

At Each Fuel Fill (It is important for you or a service station attendant to perform these underhood checks at each fuel fill.)
