Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Vehicle” in the Index. You should keep a record with a111 parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

The 8th digit sf your vehicle identification number (Vm) shows the code lettee for your engine. You will find the VIN at the top left of your instmment panel. (See “Vehicle Identifkation Number’’ in the Endex.) If you have the 3800 engine (VIN Code use regula unleaded gasoline rated at 87 octane or higher. If you’re using fuel rated at the recommended octane or higher and you 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 you have the 3800 Supercharged engine (VHN Code I), use premium unleaded gasoline rated at 91 octane or higher. With the 3800 Supercharged engine, in an emergency, you may be able to use a lower QC~XE -- as low as 87 -- if heavy knocking does not occur. If you are using 91 cx higher octane unleaded gasoline and YOU hear heavy knocking, your engine needs service.

Your vehicle may have 2 3800 Sqercharged engine. Supercharging, rather than turbocharging, emphasizes smooth, refined power. The supercharger is a device which is designed to pump more ais 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, iwreased 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 tfarsttIe cruising, the excess air that the supercharger is pumping is routed through a bypass. AB1 sf these controk working together provide high performance character and fuel efficiency in the 3800 V6 Supercharged engine. The power steering pump and reservoir are mounted on the rear (driver’s side) sf the engine biock. See “Maintenance Schedule” in the Index for when you should check the fluid.

ENGINE OIL LOW CHECK LEVEL

HMBHBMrn

Ef you have the Driver Infcmation Center, an ENGINE OIL LOW-CHECK LEVEL message will appear when the engine oil is approximately I quart (fL) Isw. 1 1 the message is displayed, check the dipstick level and add oil as needed.

Oils recommended for your vehicle can be identified by looking for the '"Starburst" symbol. Vas symbol indicates that the 0iI has been certified by the American Petroleum Institute (AH). Do not use any oil whch does not c m y this Starburst symbd.

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 02 put into your engine is American Petroleum Institute certified f ~ r gasoline engines.

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

If any one of these is true for you, use the short tripkity maintenance schedule:

Most trips are less than 5 to 13 miles (8 to I 6 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive id1ir.g (such as frequent $riving in stop-and-go traffic). Most trips are though 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. Hf any m e of these is true for your vehicle, then YOU need to change your si1 and filter every 3,000 miles (5 000 km) or 3 months -- whichever occurs k t . the Index. 1

(See Engine Oil Life Monitor (Index) in

If none of them is true, use the %ong triphighway maintenance schedule. Change the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever occurs h t . Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to $re& down dower.

Did you know that used engine oil contains certain ekmer,ts that may be unhealthy for your skin and csdd even cause cancer? Don’t let used oil stay on your skin for very iong. Clean your skin and nails with soap and water, or a good hznd 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 t-heat 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 coilects 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 kelp.

Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids md Eubricmts” 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. I. 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 one pint (0.5 L). Don’t ove@Zl.

The cooling s stem in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 MI0 h) whichever occurs first, if you add only DEX-COOL“ extended life coolant, The following explains your coding 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 DEX-COOL’ coolant will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 265 OF 129 ” C ) . Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights and gages work as they should.

NOTICE:

When adding coolant, it is importrant that you use O ~ Y DEX-CQOE~ (sficate-free) C O Q I ~ ~ . If coolant other than DEX-COOL is added to the system, premature engine, heater core or -- at radiator corrosion may result. Hw addition, the engine coolant will require change S Q B ~ ~ F 30,000 d e s (50 000 b) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOL@ is not c~vemdl by your new vehicle warranty.

Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL’ coolant which won’t damage aluminum pats. If you use this mixture, YOU don’t need to add anything else.

Adding only plain water to your cooling system can be dangerous. Blain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle’s C Q O ~ ~ warning system is set for the proper c ~ ~ l m t mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning.

Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. There are only two reasom why the brake fluid level in the reservob might go down. The first is that the brake fluid goes ~ Q W to an acceptable Bevel during n W g wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is Bedung out of the brake system. If it is, you ~ h ~ ~ l d have YQW brake system fixed, since a leak means that sooner or later YQIX brakes won't work w d , or won't work at all.

brake

So, it isn‘t a good idea to “top oft“ your brake fluid. Adding brake fluid won’t correct a leak. If YOU add fluid when your linings are worn, then you’ll have loo much fluid when you get new brake linings. You shouki add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

When you do need brake fluid, use only DOT-3 brAe fluid -- such as Delco Supreme II@ (GM Part No. 12377967). Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the mea around the cap before removing it. This will help keep dirt from entering the reservoir.

~~

~~

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

1 crash. Always use the proper brake fluid.

When your Srake 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 Waning Eight” in the Index.

NOTICE:

Using the wrong fluid can badly damage brake system parts. For example, just a few drops of minerallbased 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 gut in the wrong kind of fluid. If you spill brake fluid OEI 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 Case” in the Index.

Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear inchcators &at 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 soon your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.

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. Properiy torqued whee! nuts irre necessary to heIp prevent brake pulsation. When tires are rotated, inspect brake pacts for wear and evenly torque wheel nuts in the proper sequence to GM specifications. Brake linings should always be replaced 2s complete axle seis.

The system can alert you about a OW tire -- but it doesn’t replace normal tire maintenance. See “Tires” in the Index. When the TIRE PRESSURE LOW: CWECK TIRES message appears on the Driver Information Center, you should stop as soon as YOU can and check all your tires for damage. (If a tire is flat, see ‘‘If a Tire Goes Flat” in the Index.) Also check the tire pressure in all four tires as SOOIZ 2s you can. See “Inflati~n-Tire Pressure” in the Index. Any time you adjust tire’s pressure or have one or more tires repaired or replaced, you’ll need to reset (calibrate) tE-ae check tire pressure system. YOU’BI a~so Reed to reset the system whenever you rotate the tires, buy new rim, install or remove the compact spare, and whenever the vehicle‘s battery has been disconnected. Don’t reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire presswe system will not work properly and may ~ Q B alert you when a tire is Bow or high.

To reset (calibrate) the system:

3. Press and hold the CIC RESET button for a b u t five seconds. After five seconds, the display will show TIRE PRESSUFE RESET. Hf T I E PRESSURE RESET does not appear on the display after about five seconds, see your dealer for service. After you release the DIC RESET button, TIRE PRESSURE NORMAL will appear on the display.

The system completes the calibration process during driving. During the first 10 to 25 miles ( I5 to 40 kw) of drivhg, the system will not alert you if a tire is high or SOW. After 25 to EOO miles (40 to 160 h>, the system will oniy alert YOU about pressure differences of 12 psi (85 Wa) or more. After about 100 miles (160 h) of driving, the system will alert you if one tire is I O psi (69 kPaj different from the other thee tires.

After the tires have been rotated, adjust the Eront 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.

W e n rotating your tires, always use the correct rotation pattern shown here.

One way to tell when it’s time for new tires is to check the treadwear inciicatdlrs, which will appear when y Q x tires have only 1/16 inch (H .e mm) car less of tread remaining.

8 The tread or sidewall is cracked, cut or snagged deep

enough to show cord OF fabric.

If you ever replace YOUF tires with those not having a TPC Spec number, make sure they are the s m e size, load rmge, speed rating and ~ O I - L S ~ I U C ~ ~ Q ~ type (bias, bias-beited or radial) as your original tires.

m~

U~ffJrpx Qna&y K&-&&qg The following infomation relates to the system developed by the United States National Highway Traffic Safety'Administration, which grades tires by treadwear, traction and temperature pedommce. (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 S ~ Q W 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. IVhile the tires available on Generd Motors passenger cars and light trucks may vary with respect to these grades, they must also confom to Federal safety requirements and additional General Motors Tire Performance Criteria ( P C ) standards.

''I+he brcadwear grade is a comparative rating based Q ~ Z t tze wcx rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one m d a M f (I U2) times as well on the government course :H tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm tErrc to variations in driving habits, service practices and differences in road characteristics and climate.

'The traction grades, from highest to !owest, are A, 3, and C, and they represent the tire's ability to stop ora wet pavement as measured mder controlled conditions on specified government test surfaces of asphalt 2nd concrete. A tire marked &: may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight alead) traction tests and does not ifgcllude cornering (turning) traction.

heat and its ability to dissipate heat when tested under controlled csndidsns 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 ternperaFure can lead to sudden fire faifwe. The grade C corresponds to a level of pedomance which ail passenger c x tires must meet e~nder the Federal Motor Vehicle Safety Stmda-d No. i09. Grades B asci A represent higher levels of perhmance an the laboratory test wheel than the minimum required by law.

The wheels OR your vehicle were aligned and balanced careEulIy at the factory to give you the longest tire life acd best overall performance. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling G R ~ way OF the other, the akignment may need to be reset. If YOU notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalaaaced.

NOTICE:

Use tire chains only where Begal 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.

Don't use abrasive cleuners 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.

If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other materid may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon AmiB Powder (non-scratching glass cleaning powder), GM Bart No. 10500 1 I. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.

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 m~ntias. During very cold, damp weather more frequent application may be required. (See “Reccmmended Fluids and %ubricants” in the Index.)

The paint finish on your vehicle provides beauty, depth of color, gloss retention 2nd durability.

The best way to preserve your vehicle’s finish is to keep it dean by washing it sften with Imkewm cr cold water. Dor~’: wash your vehicle in the direct rays of the sun. h n ’ t use strong soaps or chemical detergents. Use liquid hand, dish cx car washing (mild detergent) soaps.

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

I 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.

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.

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 IOUCR-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.

Chemicals used €or ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rustj 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, Rush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in ciosed areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.

Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fail upon and attxk 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 I 2 months or 12,000 miles (20 000 km) of ourchase, whichever C C C U ~ S first.

12‘3\+7 p The remainder of this section is divided into five p m s : ”Part A: Scheduled Maintenance Services” shows what to have done and how oftec. Some of these services can be complex, so unless you are technically qualified and have the necessary equipnent, you should let your dealer’s service department or another qualified service center do these jobs.

Performing maintenance work on a vehicle can be dangerous. In trying to do some Jobs, you can be seriously injured. Do your own maintenance work O ~ Y 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. See “Service and Owner Publications” in the Index.

“Part 8: Owner Cheeks and Services” tells you what should be checked and when. It also explains what YOU can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your deater’s service department or another quaiifled service center should perfom. “Part D: Recommended Fluids and Llph~ricipn~’’ lists some recommended products to hcBp keep your vehicle properly maintained. T’kzesc 19n~lucts, or their equivalents, should be used wlacikct. you do the work yourself or have it done. “Past E: Maintenance Record’’ provides a,place for you to record the ~naintcrrance performed on your vehicle. Whenever any n:aintcnancc is performed, be sure to write it down i n Ffris part. ’ h i s will help you determine when your next nraintenance should be done. In addition, it is ;L good idca to keep your maintenance receipts. They may be rleedcd to qualify your vehicle for warranty repairs.

The proper fluids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and a 1 necessary repairs done before you or anyone else drives the vehicle. These schedules are for vehicles that:

cany passengers and cargo within recommended limits. You will find these limits on your vehicle’s Tire-Loading Information label. See “Loading Your Vehicle” in the Index. are driven on reasonable road surfaces within legal driving limits. use the recommended fuei. See “Fuel” in the Index.

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

We at General Motors want to kelp you keep your vehicle ia 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 aEB the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or YOU may drive it t o work, to do errands or in many other ways. Because of all thc different ways people use their vehicles, maintenance rreeds vary. You may even need more frequent checks and repiacements than you’ll find in the schedules in this section. So please read this section and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your Buick dealer. This part tells you the maintenance services you should have done and when you should schedule them. If you go to your dealer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts.

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

Most trips are less than 5 to 10 miles (8 to I6 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 tog of your vehicle. If the vehicle is used for delivery service, police, taxi or other commercial application.

One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down soonep:

m. B he services shown in this schedule up to IOO,QQ0 miles ( 166 000 am) should be performed after 100,800 miles ( I. 66 008 km) at the same intervals. The services shown at 150,000 miles (240 GOO km) shouid be performed at the same interval after 150,000 riles (240 000 km). See “Owner Checks and Services” m d “Periodic Maintenance inspections” following.

* The U.S. Environmental Protection Agency or the

California Air Resources Boxd has determined that the failure to perform this maintenance item will not nuIli€y the elmission wmanty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that ail recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. # Lubricate the transaxle shift linkage, parking brake cable guides and the underbody contact points and linkage.

* If your vehicle has an Engine Oil Life Monitor (Index), the monitor will show you when to change the oil -- usually between 3,000 miles ( 5 CIOC) k n ) and 7,500 miles ( 12 500 lmj since your last oil change. Under severe conditions, the indicator may come on before 3,000 wiles (5 000 h). Never drive your vehicle more than 7,500 miles (12 508 am> or i 2 months, (whichever occurs first), without an oil change. Tne system won‘: detect dust in thc oil. So if you drive in a dusty area be sure to change p u r oil every 3,000 miles (5 008 km) or sooner if: the CHANGE OIL message appears. Remember to reset the Oil Life ‘Monitor when the oil has been changed. For more information, see “Engine Oil Life ,Monitor (Index)” in the Index. + A good time to check your brakes is during tire rotation. See “Brake System Inspection” under “Periodic Maintenance Inspections” in Part C of this schedule.
