Engine Oil

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

Before closing the hood, be sure all the filler caps are on properly. Then just pull the hood down and close it firmly.

I ‘

It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The 3300 V6 engine oil dipstick is located near the front and center of the engine compartment.

The 2.2L LA engine oil dipstick is located in the fill cap near the front and center of the engine compartment. 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 dean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip lower. 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 section explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

Look for three things:

SG “SG” must be on the oil container, either by itself or combined with other quality designations, such as “SG/CC:’ “SG/CD:’ “SF, SG, CC:’ etc. These letters (API) levels of quality. show American Petroleum Institute

Just fd it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

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

231

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

Most trips are less than 4 miles (6 km). It’s below freezing outside and most trips are less than 10 miles (16 km). The engine is at low speed most of the time (as in door-to-door delivery, or in stop-and-go traffic). You tow a trailer often. Most trips are through dusty places.

If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 O00 km) or 3 months-whichever comes first. If none of them is true, change the oil every 7,500 miles (12 500 km) or 12 months-whichever comes first. Change the fdter at the first oil change and at every other oil change afier that. Engine Block Heater: An engine block 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 Block Heater” in the Index.

What to Do with Used Oil: /i\ CAUTION:

Used engine oil contains things that have caused skin cancer in laboratory animals. 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.

If you Used oil can be a real threat to the environment. change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by 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.

232

Air Cleaner

.-

Remove and replace the filter, then close the cover and latches.

If you have the 3300 V6 engine, your air cleaner is on the driver’s side of the engine compartment. To check or replace the filter, release the latches and pull the air cleaner open. Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.

If you have the 2.2L L4 engine, your air cleaner is on the driver's side of the engine compartment. To check or replace the filter, use a screwdriver to loosen the hose clamp, then lift the rubber duct. Refer to the Maintenance Schedule to determine when to replace the air filter.

Remove the wing nut and pull off the cover.

234

*

""a,

Operating the engine with the air cleaner off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn't there, and the engine backfires, you could be burned. Don't drive with it off, and be careful working on the engine with the air cleaner off.

Remove and replace the filter. Replace the cover, wing nut and rubber duct. Tighten the hose clamp.

Automatic ‘mansaxle 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.

Wait at least 30 minutes before checking the transaxle fluid level if you have been driving:

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

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

Park your vehicle on a level place. 0 Place the shift lever in “P” (Park) with the parking brake applied. 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). Let the engine run at idle for three to five minutes.

236

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

rhe dipstick on the 3300 V6 engine looks like this.

The dipstick on the 2.2L L4 engine looks like this. 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.

237

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. It doesn’t take much fluid, generally less than a pint. Don’t overfill. We recommend you use only fluid labeled DEXROP-IIE, because fluids with that label are made especially for your automatic transaxle. Damage caused by fluid other than 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.

. ..

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 where it should be, 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.

238

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:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 262” F (128” C). Protect against rust and corrosion. 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-Mi’ 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. Use GM Engine Coolant Supplement (sealer) with any complete coolant change. If you use these, you don’t need to add anything else.

I A CAUTION:

Adding only plain water to your coollng system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Mur vehicle’s coolant warning system Is set for the proper coolant mix. With plain water or the wrong mlx, your engine could get too hot but you wouldn’t get the overheat warning. b u r engine could catch fire and you or others’could be burned. Use a 50/50 mPx of clean water and a proper antifreeze.

Adding Coolant

. .

The coolant recovery tank is located on the passenger’s side of the engine compartment. To Check Coolant: When your engine is cold, the coolant level should be at “ADD:’ or a little higher. When your engine is warm, the level should be up to “FULL HOT:’ or a little higher.

240

To Add Coolant: If you need more coolant, add the proper mix at the coolant recovery tank.

/i\ CAUTION:

Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap-even a little-when the engine and radiator are hot.

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

A CAUTION:

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

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

When me engine compartment is hot, the level should be at the “H” (Hot) mark. When the engine compartment is cool, the level should be at the “C” (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.

241

washer fluid reservoir (for the wagon) is the smaller reservoir next to the coolant recovery tank. Open the cap labeled “WASHER FLUID ONLY? Add washer fluid until the bottle is full.

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

To Add: The windshield washer reservoir is located at the driver’s side of the engine compartment. The rear window

Brake Master Cylinder

Your brake master cylinder is here. It is filled with DOT-3 brake fluid. 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 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 (01 remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

A CAUTION:

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

When your brake fluid falls to a low level, your brake warning light will come on. See “Brake System Warning Light” in the Index. What to Add: When you do need brake fluid, use only DOT-3 brake fluid-such as Delco Supreme ll@ (GM Part No. 1052535). Use new brake fluid from a sealed container only.

can change in many other ways if someone puts in the wrong replacement brake parts.

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.

A CAUTION:

Batteries have acid that can burn you and gas that can explode. Ybu can be badly hurt if you aren’t careful. See “Jump Starting” in the ldex for tips on working around a battery

without getting hurt.

Contact your dealer to learn how to prepare your vehicle for longer storage periods.

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 244

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.

A CAUTION:

See “Loading b u r Vehicle” in the Index. * Underlnflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recornmended pressure. Tire pressure should be checked when your tires are cold. * Overinflated tires are more likely to be cut, punctured, or broken by a sudden Impact, such as when you hit a pothole. Keep tires at the recommended pressure. * Worn, old tires can cause accidents. If your tread Is badly worn, or If your tlps have been damaged, replace them.

Simply looking at the tires will not 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.

Inflation-Tire Pressure The Tire-Loading Inforlnation 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.

252

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.

I A CAUTION:

Rust or dirt on a wheel, or on the parts to which It Is fastened, can make the’wheel nuts become loose after a Qlme. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehlcle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to us8 a scraper or wire brush later, if you need to, to get all the rust or dirt off. (See “Changing a Flat Tlre” in the Index.)

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 tightend. 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 Information label. The tires installed on your vehicle when it was 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.

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 You can see the indicators at three places around the tire. You can see cord or fabric showing through the tire's rubber.

The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut, or other damage that can't be repaired well because of the size or location of the damage.

254

I A CAUTION:

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

Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)

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%) 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 in depart significantly from the norm due to variations 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.

255

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. Those grades are molded on the sidewalls of'passenger car tires. While the tires available as standard or optional equipment on General Motors vehicIes 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. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel'nuts should be replaced. If the wheel leaks air out, replace it (except some aluminum wheels, which can sometimes be repaired). See your Buick dealer 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 you have the right wheel, wheel bolts, and wheel nuts for your Buick model.

A CAUTION:

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

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 in a container to clean your Buick, be sure to follow the instructions. And always open your doors or windows when you're cleaning the inside. Never use these to clean your vehicle:

Gasoline Benzene Naphtha Carbon Tetrachloride Nail Polish Remover Acetone

Paint Thinner Turpentine Lacquer Thinner

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

258

Cleaning the Inside of Your Buick Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl 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. Here are some cleaning tips:

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

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

Using Solvent=Qpe Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with and mild soap. If you need to use it, then:

just water

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.)

Wipe with a clean cloth.

259

Combination Stains: Like candy, ice cream, mayonnaise, chili sauce and unknown stains.

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 Just 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 solvent-type vinyl/leather cleaner. 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.

Special Cleaning Problems Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffke with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.

Carefully scrape off excess stain. Then follow the solvent-type instructions above. 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 bleed.

Non-Greasy Stains: Like 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 above. If an odor lingers after cleaning vomit or urine, treat the area with a watedbaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Finally, if needed, clean lightly with solvent-type cleaner.

260

Care of Safety Belts Keep belts clean and dry.

A CAUTION:

Do not bleach or dye safety belts. It you do, It may severely wealeen them. In a crash they mlght not be able to provlde adequate protection. Clean safety bdta only wlth mlld soap and lukewarm M a r .

Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami Powder@ (GM Part No. 1050011). The windshield is clean if beads do not form when you rinse it with water. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn. Cleaning the Outside of Your Buick The paint finish on your vehicle provides beauty, depth 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.

of

261

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 (non-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 surfhce 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 Maintenance Materials” in the Index.) Your Buick has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat.

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, or other abrasive cleaners on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.

White Sidewall Tires Your Buick dealer has a GM White Sidewall Tire Cleaner. You can use a stiff brush with it. Weatherstrips These are places where glass or metal meets rubber. Silicone grease there will make them last longer, seal better, and not squeak. Apply silicone grease with a clean cloth at least every six months.

262

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, chemicals from industrial chimneys, and other foreign matter can damage your vehicle’s finish if they remain on painted surfaces. Use cleaners that are marked safe for painted surfaces for these stains. 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 in closed areas and other debris can collect. Dirt packed 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 fdlout. Airborne pollutants can f$ll 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 surhce. 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,OOO miles (20 OOO km) of purchase, whichever comes first.

Service Parts Identification Label You’ll find this label on your spare tire cover in the coupe or sedan. In the wagon, you’ll find the label on the wheel well (remove the spare tire cover to expose the wheel well). It’s very helpful if you ever need to order parts.. On this label is: Your VIN. Its model designation. Paint information. A list of all production options and special equipment. Be sure that this label is not. removed from. the vehicle. Add-on Electrical Equipment

This is the legal identifier. for your Buick. It appears on a plate in the front comer 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 engme code for your GM engine. This code will help you identify your engine, specifications, and replacement parts in this section.

Fuses & Circuit Breakers

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems. The fuse panel is located inside the glove box, on the left side. To change a fuse, open the glove box. Pull down on the fuse panel latch and open the door. Pull the fuse straight out. To identify and check fuses, refer to the Fuse Usage chart.

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 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.

the different ways people use

their GM

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 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.

of

“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.

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

If you.are skilled enough to do some work on your vehicle, you will probably want to get the service information GM publishes. 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 iniportant inspections that your Buick dealer’s service department or another qualified service center should perform.

277

Section A: Scheduled Maintenance Services

Using Your Maintenance Schedules This section tells you the maintenance services should have done and when you should schedule them. Your Buick dealer knows your vehicle best and wants you Loading Information label. See “Loading to be happy with it. If you go to your dealer for your Vehicle’’ in the Index. 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:

you

carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Tire- Your

are driven on reasonable road surfhces within legal driving limits. use the recommended unleaded fuel. See “Fuel” in the Index.

278

Selecting the Right Schedule First you’ll need to decide which of the two schedules is right for your vehicle. Here is 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). Most trips are less than 10 miles (16 km) when outside temperatures are below freezing. 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.

If any one (or more) of these is true for your driving, follow Schedule I. Schedule 11 Follow Schedule II only if none of the above conditions is true.

279

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

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