1993 Buick Park Avenue Owners Manual

weight to measure because it affects the total capacity weight of your vehicle. The capacity weight includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must subtract the tongue load from your vehicle’s capacity weight because your vehicle will be carrying that weight, too. See “Loading Your Vehicle” in the Index for more information about your vehicle’s maximum load capacity.

If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh 10% of the total loaded trailer weight (B). If you have a “weight-distributing” hitch, the trailer tongue (A) should weigh 12% of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer.

Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the limit for cold tires. You’ll find these numbers on the Certification label at the rear edge of the driver’s door (or see “Tire Loading” in the Index). Then be sure you don’t go over the GVW limit for your vehicle. Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow:

If you’ll be pulling a trailer that, when loaded, will weigh more than 2,000 pounds (900 kg), be sure to use a properly mounted, weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see “Carbon Monoxide” in the Index). Dirt and water can, too.

0 The bumpers on your vehicle are not intended for

hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper.

Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. Trailer Brakes If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Because you have anti-lock brakes, do not try to tap into your vehicle’s brake system. If you do, both brake systems won’t work well, or at all.

Driving with a Trailer Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly so responsive as your vehicle is by itself. Before you start, check the trailer hitch and platform, safety chains, electrical connector, lights, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lights and any trailer brakes are still working. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns.

Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. lbrn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have a different turn signal flasher and extra wiring. The green arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up,

the trailer lights will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the green arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Your vehicle has bulb warning lights. When you plug trailer lights into your vehicle’s lighting system, its bulb warning lights may not let you know if one of your lights goes out. So, when you have trailer lights plugged in, be sure to check your vehicle and trailer lights from time to time to be sure they’re-all working. Once you disconnect the trailer lights, the bulb warning lights again can tell you if one of your vehicle lights is out. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well.

On a long uphill grade, shift down to “D or 3” (Drive) and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transaxle overheating. Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into “F’”

(Park) yet.

2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.

4. Reapply the regular brakes. Then apply your parking

brake, and then shift to “ P ’ (Park).

5. Release the regular brakes.

When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down

while you:

Start your engine;

0 Shift into a gear; and 0 Release the parking brake.

2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks.

Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (don’t overfill), engine oil, belt, cooling system, and brake adjustment. Each of these is covered in this manual, and the Index will help you find them quickly. If you’re trailering, it’s a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.

Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lights will flash on and off.

210

, , . ..,

, >., :,

Press the button in to make your front and rear turn signal lights flash on and off. Your hazard flashers work no matter what position your key is in, and even if the key isn't in.

To turn off the flashers, pull out on the collar. When the hazard flashers are on, your turn signals won't work. Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (100 m) behind your vehicle.

Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your Buick. But please follow the steps below to do it safely.

A CAUTION:

Batteries can hurt you. They can be dangerous because:

They contain acid that can burn you. They contain ass that can explode or ignite. They contain enough electricity to burn you.

If you don’t follow these steps exactlp, all of these things can hurt you.

damage to your vehicle that wouldn’t be covered by your warranty. Trying to start your Buick by pushing or pulling it won’t work, and it could damage your vehicle. To Jump Start Your Buick: 1. Check the other vehicle. It must have a 12-volt

battery with a negative ground system.

2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your Buick, and the bad grounding could damage the electrical systems.

I A CAUTION:

A CAUTION:

You could be injured if the vehicles roll. Set the parking brake firmly on each vehicle. Put an automatic transaxle in “P” (Park) or a manual transaxle in “N” (Neutral).

An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing anA tools away from any underhood electric fan

3. Turn off the ignition on both vehicles. Turn off all

lights that aren’t needed, and radios. This will avoid sparks and help save both batteries. And it could save your radio!

1 NOTICE:

If you leave your ram0 or damaged. The repairs wouldn’t be covered b) your warranty.

’t could be baaly

4. Open the hoods and locate the batteries.

Find the positive (+) and negative (-) terminals on eact battery.

213

a metal engine part. Don’t connect (+) to (-) or you’ll get a short that would damage the battery and maybe other parts, too.

‘ A CAUTION:

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engines are running.

A CAUTION:

Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enoug,h water. You don’t need to add water to the Delco Freedom@ battery installed in’ every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to’ take care of that first If you don’tt, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

5. Check that the jumper cables don’t have loose or

missing insulation. If they do, you could get a shock. The vehicles could be damaged, too. Before you connect the cables, here are some basic th.ings you should know. Positive (+) will go to positive (+) a ~ d mgative (-) will go to negative (-) or

214

8. Now connect the black negative (-) cable to the good battery’s negative (-) terminal.

Don’t let the other end touch anything until the next step. The other end of the negative cable doesn’t go to the dead battery. It goes to a heavy unpainted metal part on the engine of the vehicle with the dead battery.

6. Connect the red

positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one.

7. Don’t let the other

end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.

12. Remove the cables in reverse order to prevent

electrical shorting. Take care that they don't touch each other or any other metal.

9. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The elecbical connection is just as good there, but the chance of sparks getting back to the battery is much less.

10. Now start the vehicle with the good battery and run

the engine for a while.

11. Try to start the vehicle with the dead battery.

If it won't start after a few tries, it probably needs service.

Towing Your Car Try to have a GM dealer or a professional towing service tow your Buick . The usual towing equipment is a sling-type (A) or a wheel lift (B) or car carrier (C) tow truck.

If your vehicle has been changed or modified since it was factory-new by adding aftermarket items like fog lamps, aero skirting, or special tires and wheels, these instructions and illustrations may not be correct. Before you do anything, turn on the hazard warning flashers. When you call, tell the towing service:

That your vehicle has front-wheel drive. The make, model, and year of your vehicle. Whether you can still move the shift lever. If there was an accident, what was damaged.

When the towing service arrives, let the tow operator know that this manual contains detailed towing instructions and illustrations. The operator may want to see them.

217

r /r\ CAUTION:

To help avoid injury to you or others: 0 Never let passengers ride in a vehicle that

0 Never tow faster than safe or posted

is being towed.

speeds.

0 Never get under your vehicle after it has

been lifted by a tow truck.

0 Always use separate safety chains on each

side when ?owing a vehicle.

218

When your vehicle is being towed, have the ignition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service. Do not use the vehicle’s steering column lock for this. The transaxle should be in Neutral and the parking brake released. Don’t have your vehicle towed on the front wheels, unless you must. If the vehicle must be towed on the front wheels, don’t go more than 55 mph (88 k d h ) or farther than 500 miles (SO0 km) or your transaxle will be damaged. If these limits must be exceeded, then the front wheels have to be supported on a dolly.

A CAUTION:

A vehicle can fall from a car carrier if it isn’t properly secured. This can cause a collision, serious personal injury and vehicle damage. The vehicle should be tightly secured with chains or steel cables before it is transported. Don’t use substitutes (ropes, leather straps, canvas webbing, etc.) that can be cut by sharp edges underneath the towed vehicle.

Front Towing Hook- JPS

Attach "T" hook chains behind the front wheels into the bottom slots of the cradle rails on both sides

Position a 4" x 4" wood beam across the sling chains contacting the bottom of the radiator support. Position the lower sling crossbar just behind the rear edge of the front bumper.

219

Rear Towing Hook-Ups

Attach '7"' hook chains to the slots in the bottom of floor pan just ahead of the rear wheels on both sides.

Position the lower sling crossbar directly under the rear bumper. A 4" x 4" wood beam is not needed.

Attach a separate safety chain around the outboard end of each lower control arm.

220

Engine Overheating You will find the warning light about a hot engine on your Buick instrument panel and if you have the optional gage cluster, a coolant temperature gage. You will also find a low coolant warning light on your Buick instrument panel. If Steam Is Coming From Your Engine:

A CAUTION:

- _earn from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming .. -m it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before opening the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the sngine is cool. -

If No Steam Is Coming From Your Engine: If you get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:

Climb a long hill on a hot day. Stop after high speed driving. Idle for long periods in traffic. Tow a trailer.

221

If you get the overheat warning with no sign of steam, try this for a minute or so: 1. Turn off your air conditioner. 2. Turn on your heater to full hot at the highest fan

speed and open the window as necessary.

3. If you’re in a traffic jam, shift to “N” (Neutral). If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about ten minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. If there’s still no sign of steam, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, TURN OFF THE ENGINE AND GET EVERYONE OUT OF THE VEHICLE until it cools down.

You may decide not to lift the hood but to get service help right away.

w . ._

When you decide it’s safe to lift the hood, here’s what you’ll see:

Coolant recovery tank * Radiator pressure cap Electric engine fans

I A CAUTION:

An electric fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down.

.”

The coolant level should be at or above “FULL COLD.” If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

I A CAUTION:

Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

Engine damage? Il’onl I mning bUrlr engine without coolant isn’t covered by your warrbllr

If there seems to be no leak, check to see if the electric engine fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service.

223

In cold weather, water can free

How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at or above “FULL COLD,” add a 50/50 mixture of clean water (preferably distilled) and the proper antifreeze at the coolant recovery tank. (See “Engine Coolant’’ in the Index for more information about the proper coolant mix.)

I A CAUTION: I Adding plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boll befare the proper coolant mix will. Your vehicle’s coolant warning system is set for the groper coolant mix. With plain water .of the wrung 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 50/50 mix of Glean water and a proper antifreeze.

A CAUTION:

You can be burned if you spill cootant 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 the coolant in the coolant recovery tank is at or above “FULL COLD,” start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mix directly to the radiator, but be sure the cooling system is cool before you do it.

A CAUTION:

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator

pressure cap -- even a little -- they can come out

at high speed. Never turn the pressure cap when

e cooling system, including the radiator

pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.

How to Add Coolant to the Radiator

1 1. You can remove the

radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot.

Turn the pressure cap slowly to the left until it first stops. (Don't press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap.

3. Fill the radiator with the proper mix, up to the base of the filler neck.

6. Start the engine and

let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fans.

4. Then fill the coolant recovery tank to “FULL

COLD.”

5. Put the cap back on the coolant recovery tank, but

leave the radiator pressure cap off.

7. By this time the coolant level inside the radiator

filler neck may be lower. If the level is lower, add more of the proper mix through the filler neck until the level reaches the top of the filler neck.

227

8. Then replace the pressure cap. Be sure the arrows on the pressure cap line up like this.

If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front .tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible. If your tire goes flat, the next section shows how to use your jacking equipment to change a flat tire safely.

I .

Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.

A CAUTION:

Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving:

1. Set the parking brake firmly. 2. Put the shift lever in “P” (Park). 3. Turn off the engine.

To be even more certain the vehicle won’t move, you can put chocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, a’ *?e opposite end.

The following steps will tell you how to use the jack and change a tire.

Start with the jack and the wheel wrench.

The equipment you’ll need is in the trunk.

230

The jack has a bolt at the end. Attach the wheel wrench to the jack bolt.

If your Buick has a wheel cover, you must take it off to reach the wheel nuts. Refer to the correct picture to see how to remove your wheel cover.

If your vehicle has an aluminum wheel with a center cover, remove it using the flat end of the wheel wrench.

Rotate the wheel wrench clockwise (to the right). That will raise the lift head a little.

231

If your vehicle has this aluminum wheel, you may have plastic wheel nut caps. Use the wheel nut wrench to remove the wheel nut caps and to loosen the wheel nuts.

If your vehicle has wire wheel covers, remove them as follows:

3 Use the wire wheel key

wrench to remove the wire

I wheel cover.

Put the flat end in the slot and take the small cover

Remove the theft deterrent wheel nut, by placing the key end of the wire wheel key wrench over the nut and turning it to the left. Pull off the wire wheel cover. Note: When replacing the wheel cover, carefully line up the tire valve stem and the notch in the wheel cover.

.,. .

Using the wheel wrench, loosen all the wheel nuts. Don’t remove them yet. Next, attach the wheel wrench to the bolt on the end of the jack. Raise the jack a little by rotating the wheel wrench clockwise (to the right).

Position the jack under the vehicle. There is a notch in the frame near each of the wheels. Fit the top of the jack into the notch nearest the wheel with the flat tire.

The jack handle has markings at 8” for the rear and 10” for the front, which will help you to locate the jacking notches in the frame.

1 CAUTION:

Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under

le when it is supported only by a jack.

Raising your vehicle with the jack improperly

~~

Raise the vehicle by rotating the wheel wrencn clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit. Remove all the wheel nuts and take off the flat tire.

A CAUTION:

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.

kemove any rust or dirt from the wheel bolts, mounting urfaces or spare wheel.

CAUTION:

Place the spare on the wheel mounting surface.

.*.

..

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

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. &:aF,;--..& ..*

2:. 74

r y r

Lower the vehicle by rotating the wheel wrench counterclockwise. Lower the jack completely.

Tighten the wheel nuts firmly in a criss-cross sequence as shown.

[ 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 to replace them, be sure to get the right kind. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 ft. Ibs. (140 N.mh

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.

I NOTICE:

Now put all the equipment back in the trunk.

WHEEL WRENCH

A CAU I ION:

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

Compact Spare Tire Although the compact spare was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). The compact spare is made to go up to 3,000 miles (5000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again. Your anti-lock brake system warning light may come on when you are driving with a compact spare. See “Anti-Lock Brake System Warning Light’’ in the Index.

237

/d CAUTION:

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 thesc in the proper place.

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

I A CAUTION:

If you let your tires spin at high speed, they can 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.

lestroy par __ of your Spinning your wheels vehicle as well as the tires. If you spin the whe too fast while shifting your transaxle back forth, you can destroy your transaxle.

Rocking your vehicle to get it out: First, turn your steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between “R” (Reverse) 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 Car” in the Index.

Service Your Buick dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks:

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper 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 Publications’’ 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.

CAUTION:

You can be injured 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’a and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You”cauld be hurt.

If you try to do your own service work knowing enough about it, your vehicle!l damaged.

Fuel Use regular unleaded gasoline rated at 87 octane or higher. It should meet specifications ASTM D4814 in the U.S. and CGSB 3.5-92 in Canada. These fuels should have the proper additives, so you should not have to add anything to the fuel. In the U.S. and Canada, it’s easy to be sure you get the right kind of gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And only unleaded nozzles will fit into your vehicle’s filler neck. Be sure the posted octane is at least 87. 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’re using fuel rated at 87 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.

What about gasoline with blending materials that contain oxygen, such as MTBE or alcohol? MTBE is “methyl tertiary-butyl ether.’’ Fuel that is no more than 15% MTBE is fine for your vehicle. Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than 10% ethanol is fine for your vehicle. Methanol is methyl or wood alcohol.

Fuel that is more than 5% methanol is bad for your vehicle. Don’t use it. It can corrode me parts in your fuel system and also damage plastic and rubber parts. That damage woul

these problems.

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

Fuel If you have the Supercharged 3800 V6 (L67) engine, use premium unleaded gasoline rated at 91 octane or higher. It should meet specifications ASTM D4814 in the U.S. and CGSB 3.5-92 in Canada. These fuels should have the proper additives, so you should not have to add anything to the fuel. In the U.S. and Canada, it’s easy to be sure you get the right kind of gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And only unleaded nozzles will fit into your vehicle’s filler neck. Be sure the posted octane is at least 9 1. If the octane is less than 9 1, you may get a heavy knocking noise when you drive. (In an emergency, you may be able to use lower octane - as low as 87 -- if heavy knocking does not occur.) If you’re using 91 or higher octane unleaded gas and you still get heavy knocking, your engine needs service. What about gasoline with blending materials that contain oxygen, such as MTBE or alcohol? MTBE is “methyl tertiary-butyl ether.’’ Fuel that is no more than 15% MTBE is fine for your car.

Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than 10% ethanol is fine for your car. Methanol is methyl or wood alcohol.

Fuel that is more than 5% methanol is bad for your vehicle. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your Warranty. And even at 5% or less, there must be “cosolvents” and corrosion preventers in this fuel to help avoid

You should ask your service station operators if their gasolines contain detergents and oxygenates, and if they have been reformulated to reduce vehicle emissions. Fuels in Foreign Countries If you plan on driving in another country outside the U.S. or Canada, unleaded fuel may be hard to find. Do not use leaded gasoline. If you use even one tankful, your emission controls won’t work well or at all. With continuous use, spark plugs can get fouled, the exhaust system can corrode, and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor will be damaged. All of that means costly repairs that wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving.

Filling Your Tank

The cap is behind a hinged door on the left side of your vehicle.

A r PUTION:

Gasoline vapor is highly flammable. I? burns violently, and that can cause very bad injuries. Don't smoke if you're near gasoline or refueling your vehicle. Keep sparks, flames, and smoking materials away from gasoline.

The release button is to the left of the steering column.

. .

. . . .

Or you can use the release lever in the trunk.

247

A CAUTION:

If you get gasoline on you and then something ignites it, YOU could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait I for any “hlss” noise to stop. Then unscrew the cap all the way.

’

Checking Things Under the Hood Hood Release

To open the hood, first pull the handle inside the vehicle. It is located on the lower left side of the instrument panel. When you pull this handle, the hood lock will open.

When you put the cap back on, turn it to the right until

you hear a clicking noise, 4 &

Then go to the front of the vehicle and release the secondary hood release. It is under the front edge of the grille.

A CAUTION:

An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any

I underhood electric fan.

A CAUTION:

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. -- I

Before closing the hood, be sure all the filler caps are on properly. Then just pull the hood down and close it firmly. 3800 V6 Supercharged Engine Your Park Avenue Ultra has a 3800 V6 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.

250

Engine Oil 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 engine oil dipstick is directly behind the engine fan. Turn off the engine and give the oil a few minutes to get back down into the oil pan. If you don’t, the oil dipstick might not &ow the actual level.

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 uses a remote reservoir mounted on the throttle and cruise control cable bracket. See “Maintenance Schedule’’ in the Index for when you should check the fluid. The supercharged 3800 engine uses two accessory drive belts. One belt drives the generator and the power steering pump. The second belt drives the supercharger, coolant pump and air conditioning compressor. Each belt has its own tensioner and idler pulley. See “Maintenance Schedule’’ in the Index for when you should check the accessory drive belts and supercharger oil level. Have your dealer check the oil level in the supercharger.

I

To Check Engine Oil: Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip lower.

I 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,

Use the engine oil fill cap next to the oil dipstick to add oil. 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.

When to Add Oil: If the oil is at or below the ADD line 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.

252

What Kind of Oil to Use: 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 show American Petroleum Institute (API) levels of quality.

RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

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

HOT

WEATHER

LOOK FOR THIS LABEL

If you use oils that don’t have the “SG” designation, you can cause engine damage not covered by your warranty.

SAE 1OW-30 PREFERRED above 0°F

(-18%)

SAE 5W-30

COLD

WEATHER

IF NEITHER SAE 5W-30 NOR SAE 1OW-30 GRADE OILS ARE AVAILABLE, SAE 30 GRADE MAY BE USED AT TEMPERATURES ABOVE 40 DEGREES F (4 DEGREES C). DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED

0 SAE low-30

As shown in this 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 O F (1 6 ” C) before your next oil change. When it’s very cold, below 0°F (- 18 ” C), 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 low-40 or SAE 20W-50. 0 Energy Conserving I1

Oils with these words on the container will help you save fuel.

This doughnut-shaped logo (symbol) is used on most oil containers to help you select the correct oil. You should look for this on the oil container, and use only those oils that display the logo. GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the requirements for your vehicle. Engine Oil Additives: Don’t add anything to your oil. Your Buick dealer is ready to advise if you think something should be added.

When to Change Engine Oil: See if any one of these is true for you: 0 Most trips are less than 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).

0 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 (5 000 km) or 3 months -- whichever comes first. (See “Change Oil Soon” in the Index.) If none of them is true, change the oil every 7,500 miles (12 500 km) or 12 months -- whichever comes first. Change the filter at the first oil change and at every other oil change after that. (See “Change Oil Soon” in the Index.) Engine Block Heater: An engine block heater can be a big help if you have to park outside in very cold weather, -20” F (-29 “C) or colder. If your vehicle has this option, see “Engine Block Heater.” in the Index.

What to Do with Used Oil:

Air Cleaner

A CAUTION:

Used engine oil contains things that have cause 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 0"

Used oil can be a real threat to the environment. Don't ever dispose of it 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.

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

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

A CAUTION:

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.

: NOTICE: I If the air clean i 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.

Automatic Transaxle Fluid When to Check and Change: A good time to check your automatic transaxle fluid level is when the engine oil is changed. Refer to the Maintenance Schedule to determine when to change your fluid. See “Scheduled Maintenance Services” in the Index. How to Check: Because this operation can be a little difficult, you may choose to have this done at a Buick dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

transaxle. Too much can mean that some of the fluid could come out and fall on hot engine parts, starting a fire. Be sure to get an a if you check your transaxle fluid.

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

three seconds in each range. Then, position the shift lever in “ P ’ (Park).

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

0 While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 1 80 F to 200 F (82OC to 93OC). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures .are above 50 F (10OC). 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.

0 With your foot on the brake pedal, move the shift

lever through each gear range, pausing for about

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

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

paper towel.

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

then pull it back out again.

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. 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 DEXRONWIE, because fluids with that label are made especially for your automatic transaxle. Damage caused by fluid other than DEXRONB-IIE is not covered by your new vehicle warranty. 0 After adding fluid, recheck the fluid level as

described under “How to Check.” When the correct fluid level is obtained, push the dipstick back in all the way.

Engine Coolant The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. The proper coolant for your Buick will: 0 Give freezing protection down to -34°F (-37 “C) . 0 Give boiling protection up to 262 F ( 128 ” C) . 0 Protect against rust and corrosion. 0 Help keep the proper engine temperature. 0 Let the warning lights work as they should.

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

A CAUTION:

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 vehicle’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 50/50 mix of clean water and a proper antifreeze.

If you use an improper coolant mix, your engine :,,I

Adding Coolant

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

259

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

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

‘

CAUTION:

T‘urning 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 turn the radiator pressure cap -- even a little - never have to add coolant at the radiator. Never #hen 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.

Radiator Pressure Cap

Power Steering Fluid

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

be on t

ov

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.

How To Check Power Steering Fluid: Unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.

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

0 When the engine compartment is cool, the level

should be at the “FULL COLD” mark.

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

NOTICE: When adding power steering fluid or making a complete fluid change, always use the proper fluid. Failure to use the proper flui leaks and damage hoses and seals

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 (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

I- A CAUTION:

it can spill on

If you have too much brake fluid, 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 and a chime will sound. What to Add: When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 @ (GM part No.1052535). Use new brake fluid from a sealed container only.

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 Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedoms 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. 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. Halogen Bulbs

Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Take special care when handling and disposing of halogen bulbs.

Headlamp Bulb Replacement

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

Each headlamp is attached by retainers with round plastic knobs.

Lift the headlamp away from the car.

Taillamp Bulb Replacement

Turn the bulb socket 1/4 turn counter-clockwise, while pressing it firmly.

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

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

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.

0 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.

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 Ha). How to Check: Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires -- which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture. Tire Inspection and Rotation To make your tires last longer, have them inspected and rotated at the mileages recommended in the Maintenance Schedule. See “Scheduled Maintenance Services” in the Index.

Use this rotation pattern. After the tires have been rotated, adjust the front and rear inflation pressure as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.

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.)

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.

0 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.

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

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

.\ CAUTION:

Xing tires could cause you to lose control hile driving. If you mix tires ob different sizes or types (radial and bias-betted tires;), the vehicle may not handle properly, and you coutd have a crash. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare, bbugh. It was developed for limited use on your

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

Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1

1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction - A, B, C The traction grades, from highest to lowest are: A, B, and C. They represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include cornering (turning) traction. Temperature - A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.

The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Those grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades. Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance.

In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Wheel Replacement Replace any wheel that is bent, cracked or badly rusted. 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
