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.

of steam,

If you get the overheat warning with no sign try this for a minute or so: 1. 2.

If you have an air conditioner, turn it off. Turn on your heater to full hot at the highest fan speed and open the window as necessary. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving -- AUTOMATIC OVERDRIVE (03) or DRIVE (D) for automatic transmissions.

3.

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 oflthe engine and get everyone out of the vehide until it cools down. You may decide not to lift the hood but to get 'service help right away.

Engine damage from running your engine without coolant isn’t covered by your warranty.

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

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.

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 a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.

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

The equipment you’ll need is in the right (pasq-enger) rear area behind the trim panel. First you must remove the close-out panel. See “Close-Out Panel’’ in the Index.

5-31

On convertible models, you must also remove the trunk accem panel. It's at the upper back of the trunk. Turn the two screw knobs under the trunk edge a quarter turn counterclockwise to remove the panel. Use a coin or a key to turn the screw heads until the slots poht fkont and back. Gently lift the trim panel and move it out of the way. If you have speakers in the trim panel, the speaker wire should be long enough to remove the trim panel without disconnecting the wire.

11.: '*

To remove the jack and wheel wrench, lomen and remove the bolt and remove the plastic cover.

5-32

Remove the wing nut and adapter and pull out the spare.

Start with the jack (A) and wheel wrench (B).

5-33

The jack has a bolt at the end. Attach the wheel wrench to the jack bolt. Turn the wheel wrench to the right to raise the lift head a little.

If your wheel has a bolt-on center cap, loosen the plastic caps using the wheel wrench.

Then pry off the center cap with the wheel wrench.

If your vehicle has optional alloy wheels, each wheel may have one locknut in place of the standard wheel nut. A special wheel lock key (removal tool) and instructions are located in the center console. Attach the wheel lock key to the socket of the wheel wrench. Remove the locking wheel nut by turning counterclockwise.

Using the wheel wrench, loosen all the wheel nuts. Don’t remove them yet.

, .i.. ,.

fl

Position the jack under the vehicle. There is a notch in the vehicle’s rocker flange on the coupe model. Raise the jack head until it fits f i i y into the notch nearest the flat tire.

Stay away from the moldings or fender flanges to avoid damaging them.

NOTICE: Raising your vehicle with the jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack. Be sure to fit the jack lift head into the proper location before raising your vehicle.

5-37

Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. Place the spare on the wheel mounting surface.

Raise the vehicle by rotating the wheel wrench 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.

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.

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

5-39

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

Don’t try to put a center cap on your compact spare tire. It won’t fit. Store the center cap in the rear area until you have the flat tire repaired or replaced.

NOTICE: Center caps won’t fit on your compact spare. If you try to put a center cap on your compact spare, you could damage the cover or the spare.

I I NOTICE:

Don’t take your compact spare 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.

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). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly 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 in case you need it again.

NOTICE: If the compact spare is used as a rear tire, do not 1 drive faster than 50 mph (80 km/h). Damage to the rear axle may occur if the compact spare is driven faster than 50 mph. This speed limitation does not apply when the compact spare is used as a front tire.

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

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 transmission back and forth, you can destroy your transmission.

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 (or with a manual transmission, between FIRST or SECOND (2) gear and REVERSE), spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator in gear. If that doesn’t pedal when the transmission is 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.

Gasolines for Cleaner Air Your use of gasoline with deposit control additives will help prevent deposits from forming in your engine and fuel system. That helps keep your engine 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 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 deposit control additives 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 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).

Engine Oil

LOW OIL

If the LOW OIL light on the instrument panel comes on, it means you need to check your engine oil level right away. For more information, see LOW OIL in the Index. You should check your engine oil level regularly; this is an added reminder. 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. 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 down, and check the level.

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

What Kind of Oil to Use Oils of the proper quality for your vehicle can be identified by looking for the “Starburst” symbol. The “Starburst” symbol indicates that the oil has been certified by the American Petroleum Institute (API), and is preferred for use in your gasoline engine.

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.

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.

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 ihto 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:

Engine Oil Additives Don’t add anything to your oil. Your Pontiac 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:

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 car.

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. If none of them is true, change the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever comes first.

Engine Coolant Heater An engine coolant heater can be a big help if you have to park outside in very cold weather, 0 O F (- 1 8 O C) or colder. If your vehicle has this option, see “Engine Coolant Heater” in the Index. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. 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. you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Automatic Transmission Fluid When to Check and Change A good time to check your automatic transmission 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 your Pontiac dealer 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 transmission. 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 accurate reading if you check your transmission fluid.

4. Open the air cleaner and remove the filter.

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

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

To get the right reading, the fluid should be at normal operating temperature, which is 180" F to 200" F (82°C to 93°C). To check transmission fluid hot: Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures &e above 50°F (10°C). If its colder than 50" F (10" C) drive the vehicle in DRIVE (D) until the engine temperature gage moves and then remians steady for ten minutes. Then follow the hot check procedures.

To check transmission fluid cold: A cold check is made after the vehicle has been sitting for eight hours or more with the engine off and is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more. If it's colder than 50°F (lO"C), you may have to idle the engine longer. Should the fluid level be low during a cold check, you must perform a hot check before adding fluid. This will give you a more accurate reading of the fluid level. To check the fluid hot or cold:

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 minutes or more.

How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid only after checking the transmission fluid HOT. (A COLD check is used only as a reference.) If the fluid level is low, add only .enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than a pint. Don ’t oveflill. We recommend you use only fluid labeled DEXRON@-III, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRON@-111 is not covered by your new vehicle warranty.

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

Manual Transmission Fluid How to Check Because this operation can be difficult, you may choose to have this done at your Pontiac dealer Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading.

NOTICE: Too much or too little fluid can damage your transmission. 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 accurate reading if you check your transmission fluid.

Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission cool enough for you to rest your fingers on the transmission case.

Then, follow these steps: 1. Remove the filler plug. 2. Check that the lubricant level is up to the bottom of

the filler plug hole.

3. If the fluid level is good, install the plug and be sure

it is fully seated. If the fluid level is low, add more fluid as described in the next steps.

How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough bottom of the

When to Check and What to Use

Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It isn’t a good idea to “top off’ your clutch fluid. Adding fluid won’t correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See “Owner Checks and Services’’ and “Recommended Fluids and Lubricants’’ in the Index.

6-28

How to Check The proper fluid should be added if the level is below the “STEP” mark on the reservoir. See the instructions on the reservoir cap. Rear Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See “Periodic Maintenance Inspections” in the Index. add How to Check Lubricant If the level is below the bottom of the filler plug hole, (GM Part you’ll need to add some lubricant. Add enough lubricant lubricant. to raise the level to the bottom of the filler plug hole.

What to Use Standard Differential Use Axle Lubricant (GM Part No. 1052271) or S A E 8OW-90 GL-5 gear lubricant. Limited-Slir, Differential To add lubricant when the level is low, use Axle Lubricant (GM Part No. 1052271) or SAE SOW-90 GL-5 gear lubricant. To completely refill after draining,

4 ounces (1 18 ml) of Limited-Slip Differential

Lubricant Additive (GM Part No. 1052358). Then fill to the bottom of the filler plug hole with

Axle Lubricant No. 12345977) or SAE SOW-90 GL-5 gear

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 or if you need to add coolant to your radiator, see “Engine Overheating” in the Index. The proper coolant for your Pontiac will:

Give freezing protection down to -34°F (-37 O C). Give boiling protection up to 262 “F ( 128 ” C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights work as they should.

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

I 6-30

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.

Adding Coolant

5.7L LTl Engine Only

r ----

To Check Coolant When your engine is cold, check the dipstick on the cap of the coolant recovery tank. The coolant level should be at COLD, or a little higher. When your engine is warm, the level on the dipstick should be up to the HOT, or a little higher.

If this light comes on, it means you’re low on engine coolant. To Add Coolant to the Recovery Tank If you need more coolant, add the proper mix at the coolant recovery tank, but only when your engine is cool. If the tank is very low or empty, also add coolant to the radiator, see “Engine Overheating” in the Index for information.

Radiator Pressure Cap (All Engines)

NOTICE: Your radiator cap is a 18 psi (124 E a ) pressure-type cap and must be tightly installed 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.

to

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.

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

NOTICE:

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

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water.

0 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.

0 Fill your washer fluid tank only 3/4 full

when it’s very cold. This allows for expansion, which could damage the tank if it is completely full.

0 Don’t use radiator antifreeze in your

windshield washer. It can damage your washer system and paint.

6-36

in There are only two reasons why the brake fluid level 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

I

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.

To Check Brake Fluid

Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections” in the Index.

You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above the plastic seam in the reservoir. If it isn’t, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the plastic seam, near the base of the filler neck.

6-37

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

(GM Part

NOTICE:

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

6-38

Brake Wear Unless you have the four-wheel disc brake option, your Pontiac has front disc brakes and rear drum brakes. Disc brake pads have built-in wear indicators that make high-pitched wanzing 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).

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. If you have rear drum brakes, they 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 rapidincrease in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a moderate brake stop, your disc brakes adjust for wear. If you rarely make a moderate or heavier stop, then your brakes might not adjust correctly. If you drive in that way, then -- very carefully -- make

a few moderate brake stops about every 1,000 miles (1 600 km), so your brakes will adjust properly. If your brake pedal goes down farther than norrid, your rear drum brakes may need adjustment. Adjdsi them by backing up and firmly applying the brakes a few times. Replacing Brake System Parts The braking system on a modern vehicle is complkx. Its many parts have to be of top quality and wokk well. together if the vehicle is to have really good briking. Vehicles we design and test have top-quality GM brake parts in them, as your Pontiac does when When you replace parts of your braking system, -- for example, when your brake linings wear down dnd yob have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don’t, yuia brakes may no longer work properly. For em$le, if someone puts in brake linings that are wrong €& ybuf vehicle, the balance between your front and re& btakes can change -- for the worse. The braking perfoi-mhnce , you’ve come to expect can change in many other way$ if someone puts in the wrong replacement brake parts.

I I Tires , We don’t make tires. Your new vehicle comes with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new Pontiac. Tf your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

6-48

Inflation - Tire Pressure

The Tire-Loading Information label which is on the driver’s door shows the correct inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than a mile. If you’ll be driving at speeds higher than 100 mph (160 km/h) where it is legal, raise the “cold” inflation pressure of each tire to 35 psi (240 k Pa). When you end this very high speed driving, reduce the “cold” inflation pressures to those listed on the tire loading information label.

Don’t let anyone tell you that underinnation or overinflation is all right. It’s not. If’ your tires don’t have enough air (underinflation) you can get:

Too much flexing Too much heat Tire overloading Bad wear

0 Bad handling

Bad fuel economy.

NOTICE: (Continued) If your tires have too much air (overinflation), you can get:

Unusual wear Bad handling 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. 60 psi (420 kPa). 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 ou,t dirt 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 your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When it’s Time 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.

If you don’t have P245/5OZR16 Goodyear Eagle GS-C tires, use the rotation pattern shown above for your tires.

If you have P245/5OZR16 Goodyear Eagle GS-C tires, they must roll in a certain direction for the best overall performance. The direction is shown by an arrow on both sidewalls. Because these tires are directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front on the same side of the vehicle.

6-50

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.

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 1/16 inch (1.6 mm) or less of tread remaining.

6-51

You need a new tire if

You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut, or other damage that can’t be repaired well because of the size or location of the damage.

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.

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

6-52

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 €3 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 overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. These grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with 6-53

inflated and not

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 Pontiac model.

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 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 Pontiac dealer if any of these conditions exist.

6-54

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

Used Replacement Wheels

Tire Chains

NOTICE: If your Pontiac has P235/55R16, or P245/50ZR16 size tires, don’t use tire chains; they can dqpage 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 your tires. Install them on the rear 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 Pontiac, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle: 0 Gasoline 0 Benzene 0 Naphtha

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 0 Reducing Agents Cleaning the Inside of Your Pontiac Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Pontiac 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. 0 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.

0 Use solvent-type cleaners in a well-ventilated area

only. If you use them, don’t saturate the stained area.

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

Using Foam-Type Cleaner on Fabric

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

NOTICE: Be careful. A blow dryer may scorch the fabric.

0 Wipe with a clean cloth. Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent:

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. (See the previous NOTICE.)

For stubborn stains, use a mild solution of 10% isopropyl alcohol (rubbing alcohol) and 90% water. Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. Soiled leather should be cleaned immediately. If dirt is allowed to work into finish, it can harm the leather.

Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.

Weatherstrips Silicone grease on weatherstrips will make 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 Pontiac 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 f”mish 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 Pontiac 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 Pontiac has a “basecoatklearcoat” 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 basecoatklearcoat paint f ~ s h .

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 Pontiac garaged or covered whenever possible.

Cleaning Your Convertible Top

NOTICE: When using an automatic car wash, set your heating or cooling system to “VENT” with the fan speed set to the second highest speed. This will prevent high pressure water from entering around your top.

Your convertible top should be cleaned often. Use a mild soap, lukewarm water and a soft brush. Don’t use any harsh cleaners or bleaching agents on the top. They can darnage the material. When the top is really dirty, use a mild foam-type cleaner. Use a cloth or sponge to remove the dirt. Thoroughly rinse the top and dry it before lowering it. A damp top causes wrinkles.
