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


Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.


Replace the wheel nuts with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.


10. Lower the vehicle by rotating the wheel wrench


counterclockwise. Lower the jack completely.


i


11. In a crisscross sequence;


tighten the wheel nuts firmly.


NOTICE:


A CAUTION:


Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have new GM original to replace them, be sure to get equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100’lb-ft (140 N-m).


Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification.


Don’t try to put a wheel cover on your compact spare tire. It won’t fit. Store the wheel cover in the trunk until you have the flat tire repaired or replaced.


NOTICE:


Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare.

7 the Flat Tire and Tools


Store the flat tire as far forward in the trunk as possible. Store the jack and wheel wrench in their compartment in the trunk.


Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.


After you’ve put the compact spare tire on your vehicle, you’ll need to store the flat tire in your trunk. Use the following procedure to secure the flat tire in the trunk.


Storing the Spare Tire and Tools


Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.


Store the compact spare tire and tools as shown in the diagram.


The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See “Compact Spare Tire” later in this section.


Compact Spare Tire, Although the compact spare tire was fully inflated when y o q vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 P a ) . After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is corre,ctly 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 @ case you need it again.


NOTICE:


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


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


NOTICE:


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

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


at high speed, they can


If you let your tires SI explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer.


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. If your vehicle has traction control, you should turn the 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.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Buick Service Manual. It tells you much more about how to service your Buick than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Buick” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.


You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. Be sure you have sufficient knowledge, experience, and the proper replacement parts and tools before you attempt any vehicle maintenance task. Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.


6-2


Fuel The 8th digit of your vehicle identification number (VIN) shows the code letter for your engine. You will find the VIN at the top left of your instrument panel. (See “Vehicle Identification Number” in the Index.) If you don’t have the 3800 Supercharged engine (VIN Code l), use regular unleaded gasoline rated at 87 octane or higher. If you have the 3800 Supercharged engine, use premium unleaded gasoline rated at 91 octane or higher. At a minimum, the gasoline you use should meet specifications ASTM D4814 in the United States and CGSB 3.5-M93 in Canada. Improved gasoline specifications have- been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting ihe AAMA specification could provide improved driveability and emission control system protection compared to other gasolines. Be sure the posted octane for premium is at least 91 (at least 89 for middle grade and 87 for regular). If the octane is, less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine.




If you have the 3800 Supercharged engine, in an emergency, you may be able to use .a lower octane -- as low as 87 -- if heavy knocking does not occur. If you are using 91 or higher octane unleaded gasoline and you still h e q heavy knocking, your engine needs service. , If you’re using fuel rated at the recommended octane or higher and you still hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. If your vehicle is certified to meet California Emission Standards (indicated on the underhood tune-up label), it is designed to operate’on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Buick dealer for diagnosis to determine,the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty.


6-3


If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

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


I NOTICE:


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

Engine Oil


If the CHECK OIL LEVEL light on the instrument panel comes on, it means you need to check your engine oil level right away.


CHECK OIL


LEVEL


For more information, see “Check Oil Level Light” in the Index. You should check your engine oil level regularly; this is an added reminder.


Your Park Avenue Ultra has a 3800 Supercharged engine. Buick chose supercharging rather than turbocharging because Buick emphasizes smooth, refined power. The supercharger is a device which is designed to pump more air into the engine than it would normally use. This air mixed with fuel creates increased engine power. Since the supercharger is a pump and is driven from an engine accessory drive belt, increased pressure is available at all driving conditions. The Powertrain Control Module (PCM) works with a vacuum control to regulate the increased pressure required during specific driving conditions. When this increased pressure or boost is not desired, such as during idling and light throttle cruising, the excess air that the supercharger is pumping is routed through a bypass. All of these controls working together provide high performance character and fuel efficiency in the 3800 V6 Supercharged Buick engine. The power steering pump and reservoir are mounted on the rear (driver’s side) of the engine block. See “Maintenance Schedule” in the Index for when you should check the fluid.


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.


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


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


NOTICE:


Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged.


Add engine oil at the engine oil fill cap next to the oil dipstick. Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.


What Kind of Oil to Use Oils recommended for your vehicle can be identified by looking for the “Starburst” symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this Starburst symbol.


If you change your own oil, be sure you use oil that has the Starburst symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for gasoline engines.


You should also use the proper viscosity oil for your vehicle, as shown in the following chart:


RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS


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

As shown in the chart, SAE 1OW-30 is best for your vehicle. However, you can use SAE 5W-30 if it’s going to be colder than 60°F (1 6°C) before your next oil change. When it’s very cold, you should use SAE 5W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50.


I NOTICE:


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

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


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


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


If the optional CHANGE OIL SOON light comes on, you will need to change your oil sooner than either mileage specified. Depending upon driving habits, the CHANGE OJL 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. 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.


1. Remove the screws on the air cleaner housing cover.


Before servicing the air cleaner, the Powertrain Control Module (PCM) cover must be removed. Remove the two wing nuts to remove the PCM cover.


2. Remove the air intake hose that snaps over the


throttle body by pulling the hose upward and away from the throttle body. After detaching the hose from the throttle body, then pull back the entire rear portion of the air cleaner by pulling upward and rearward.


3. Replace the air filter. 4. Reinstall the rear section of the air cleaner. 5. Reattach the air intake hose. 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.


Unless you are technically qualified and have the proper tools, you should let your dealer or a qualified service center perform this maintenance.


When to Check Check oil level every 30,000 miles (50 000 km) or every 36 months, whichever occurs first. What Kind of Oil to Use See “Recommended Fluids and Lubricants’’ in the Index and use only the recommended oil.


6-19


How to Check and Add Oil Check oil only when the engine is cold. Allow the engine to cool two to three hours after running.


If you remove the supercharger oil fill plug while the engine is hot, pressure may cause hot oil to blow out of the oil fill hole. You may be burned. Do not remove the plug until the engine cools.


1. Remove the wiring harness shield. 2. Clean the area around the oil fill plug before


removing it.


3. Remove the oil fill plug using a 3/16 Allen wrench. 4. The oil level is correct when it just reaches the


bottom of the threads of the inspection hole.


5. Replace the oil plug with the O-ring in place. Torque


to 88 lb-in (10 N-m).


6. Replace wiring harness shield.


Automatic Transaxle Fluid When to Check and Change A good time to check your automatic transaxle fluid level is when the engine oil is changed. Change both the fluid and filter every 50,000 miles (83 000 km) if the vehicle is mainly driven under one or more of these conditions: 0 In heavy city traffic where the outside temperature


regularly reaches 90 OF (32 O C) or higher.


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


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


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


How to Check Because this operation can be a little difficult, you may choose to have this done at your h i c k 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 parts, starting a fire. Be sure to get an acc ate reading if you check your transaxle fluid.


UT


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).


0 At high speed for quite a while. 0 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 (1.0"C). If it's colder than 50°F (lO"C), you may have to drive longer. Checking 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). 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). Let the engine run at idle for three to five rhinutes.


6-21


I


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


1. The transaxle fluid


dipstick top is a round loop and is next to the brake master cylinder behind the engine block. Pull out the dipstick and wipe it


I 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.


6-22


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.


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 (0.5 L). Don’t ovel-fill. We recommend you use only fluid labeled [email protected], because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON-I11 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 in all the way.


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


Give freezing protection down to -34°F (-37°C).


9 Give boiling protection up to 265 OF ( 129 O C).


Protect against rust and corrosion. Help keep the proper engine temperature.


0 Let the warning lights and gages work as they should.


NOTICE:


When adding coolant it is important that you use DEX-COOL TM (orange-colored, silicate-free) coolant meeting GM Specification 6277M. If silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine


coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first.


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


‘ A CAUTICY:


Adding only plain water to your cooling system ,can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehi.cle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50150 mix-of clean water and DEX-COOL silicate-free) antifreeze.


(orange-colored,


NOTICE:


If you use .an improper coolant mix, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mix can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system.


~~


NOTICE:


If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.


6-25


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


COOLANT


LOW


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


Checking Coolant


The coolant recovery tank is located at the left of the engine compartment. When your engine is cold, the coolant 'level should be at F'ULL COLD or a little higher. When your engine is warm, the level should be up to F'ULL HOT or a little higher.


n r n i n g the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the


radiator pressure cap -- even a little -- when the


engine and radiator are hot.


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


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


Radiator Pressure Cap


NOTICE:


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


When you replace your radiator pressure cap, an [email protected] 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 [email protected] thermostat is recommended.


Power Steering Fluid


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


The power steering fluid reservoir on the L36 and L67 engine is located below the alternator and behind the accessory drive belt on the driver’s side toward the rear of the engine. 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. If necessary, add only enough fluid to bring the level up to the mark. What to Use Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.


Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Adding Washer Fluid


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


NOTICE:


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

Brakes Brake Fluid


There are only two reasons why the brake fluid level in the reservoir might go down. ,The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake


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


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


When your brake fluid falls to a low level, your brake warning light will come on. A chime will sound if you try to drive with this warning light on. See “Brake System Warning Light” in the Index.


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


(GM Part


A CAU”’3N:


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


I NOTICE:


Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.


6-31


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).


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


I NOTICE:


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


Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Free movement of brake calipers and properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake calipers for movement, brake pads for wear, and evenly torque wheel nuts in the proper sequence to GM specifications. Your rear drum brakes don’t have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. 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. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear.


Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your 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. Battery Every new Buick has a Delco [email protected] battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label.


Vehicle Storage 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.


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


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


Bulb Replacement The following procedure tells you how to replace your headlamp bulbs. Halogen Bulbs


Headlamps


Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Be sure to read and follow the instructions on the bulb package.


Each headlamp is attached by retainers with round plastic knobs.


1. Remove the retainers by turning in a


counterclockwise direction.


2. Lift the headlamp away from the car.


6-35


3. Turn the bulb socket


one-quarter turn counterclockwise, while pressing it firmly. 4. Remove the wire


connector from the bulb by lifting the lock tab and pulling it away from the plastic base.


Taillamps


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 lamps 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 one-quarter 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 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 one-quarter turn and pull it out. Pull the bulb straight out from the socket. The back-up bulb can be replaced by squeezing the lock on the socket, turning it one-quarter turn and pulling it out. Pull the bulb straight out. Reverse the above steps to reassemble the lamp and the trunk trim.


Windshield Wiper Blade Replacement


Replacement blades come in different types and are removed in different ways. Here’s how to remove the type with a release clip: 1. Pull the windshield wiper arnn away from the windshield. 2. Push down on the release clip with a screwdriver and


pull the blade assembly off the wiper arm.


3. Push the new wiper blade securely on the wiper arm. For the correct windshield wiper blade replacement length and type, see “Capacities and Specifications’’ in the Index.


Tires We don’t make tires. Your new Buick comes with high-quality tires made by a leading tire manufacturer. If you ever have qu,estions about your tire warranty and where to obtain service, see your Buick Warranty booklet for details.



A C IUTION:


Poorly maintained and improperly used tires are dangerous.


Overloading your tires can cause overheating as a result of too much friction. You could have an a b o u t and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more likely to be cut, punctured or broken by a sudden


impact -- such as when you hit a pothole.


Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.


6-39


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 sittkg for at least three hours or driven no more than 1 mile (1.6 km).


.NOTICE:


Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: 0 Too much flexing 0 Too much heat 0 Tire overloading 0 Bad wear


Bad handling Bad fuel economy.


(Continued)


6-40


NOTICE: (Continued)


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


Unusual wear Bad handling


0 Rough ride 0 Needless damage from road hazards.


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


,


Tire Inspection and Rotation Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km) for any signs of unusual wear. If unusual wear is present, rotate yourtires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s T h e 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.


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


A CAUTION:


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


6-41


7 One way to tell when it’s


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


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


around the tire.


0 You can see cord or fabric showing through the


tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.


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


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


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


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


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


The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to Federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.


Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.


Traction -- A, B, C


The traction grades, from highest to lowest, are A, B, and C, and they represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straightahead) traction tests and does not include cornering (turning) traction.


Temperature -- A, By C


The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109.


Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.


Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your 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.


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


NOTICE:


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


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

Used Replacement Wheels


A CAUTION:


rire P a i n s


NOTICE:


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


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 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 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:


Gasoline Benzene 0 Naphtha


Carbon Tetrachloride 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.


Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: 0 Alcohol 0 Laundry Soap 0 Bleach


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. If a ring forms after spot cleaning, clean the entire area immediately or it will set.


Using Foar ’ me Cleaner on Fabric 1. Vacuum and brush the area to remove any


loose dirt.


2. Always clean a whole trim panel or section. Mask


surrounding trim along stitch or welt lines.


3. Mix Multi-Purpose Powdered Cleaner following


the directions on the container label.


4. Use suds only and apply with a clean sponge. 5. Don’t saturate the material. 6. Don’t rub it roughly. 7. As soon as you’ve cleaned the section, use a sponge


to remove the suds.


8. Rinse the section with a clean, wet sponge. 9. Wipe off what’s left with a slightly damp paper


towel or cloth.


10. Then dry it immediately with a blow dryer. 11. 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. 6-48


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 a blow dryer to help prevent a cleaning ring.


Special Cleaning Problems Greasy or Oily Stains Stains caused by grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt can be removed as follows: 1. Carefully scrape off excess stain. 2. Follow the solvent-type instructions described earlier. 3. Shoe polish, wax crayon, tar and asphalt will stain if


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


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


soiled area with cool water.


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


described earlier.


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


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


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


For stubborn stains, use a GM Vinylbeather Cleaner or equivalent product.


0 Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather.


0 Soiled leather should be cleaned immediately. If dirt is allowed to work into the finsh, it can hann the leather.


Care of Safety Belts Keep belts clean and dry.


Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.


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. Some spots and stains will clean off better with just water and mild soap. If something gets on one of them and you need to use a solvent, follow these steps: 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 a blow dryer to help prevent a cleaning ring.


6-50


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 [email protected] (GM Part No. 105001 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” in the Index.) 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 are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting.


High pressure car washes may cause water to enter your vehicle. Finish Care Occasional waxing or mild polishing of your Buick by hand 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.


I NOTICE:


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


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


NOTICE:


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


Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to the parts repaired or replaced to restore corrosion protection.


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 occurs first.


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 car washing system can do this for you.

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.


Electrical System Add-on Electrical Equipment


I 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.


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.


Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the underhood fuse center. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp 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.


6-57


MaxifuseslRelay Center To check the fuses in this underhood fuse center, turn the two knobs one-quarter 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 11 fuse is located in the right side relay center. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.


Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can. There are two fuse blocks in your vehicle: the driver’s side and passenger’s side fuse blocks.


- - er ’s Slae r ‘use Panel The left side fuse panel is located under the instrument panel, next to the parking brake.


When finished, replace the cover by pressing it back up into place.


Snap off the cover to reveal the fuses. 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. Spare fuses are located in the slots labeled “Spare” on the following chart.
