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.

Section 5 Problems on the Road

Here you'll find what to do about some problems that can occur on the road. Hazard Warning Flashers

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

Press the switch to make your front and rear turn signal lamps flash on and off. Your hazard warning flashers work no matter what position your key is in,

To turn off the flashers, press the switch again. When the hazard warning flashers are on, your turn signals won't work.

Other Warning Devices If you c m y 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 Pontiac. But please follow the steps below to do it safely.

NOTICE: Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty. Trying to start your Pontiac by pushing or pulling won’t work, and it could damage your vehicle.

To Jump Start Your Pontiac 1. Check the other vehicle. It must have a 12-volt

battery with a negative ground system.

NOTICE: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged.

5-2

2.

3.

Get the vehicles cbse 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 Pontiac, and the bad grounding could damage the electrical systems. You could be injured if the vehicles roll. Set the parking brake firmly on each vehicle. Put an automatic transaxle in PARK (P) or a manual transaxle in NEUTRAL (N). Turn off the ignition on both vehicles. Turn off all lamps that aren’t needed, and radios. This will avoid sparks and help save both batteries. And it could save your radio!

NOTICE: If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty.

4.. Open the hoods and locate the batteries.

5 . Find the positive (+) and negative (-) terminals on each battery. Your Pontiac has a remote positive (+) jump starting terminal. The terminal is on the same side of the engine compartment as your battery. You should always use the remote positive (+) terminal instead of the positive (+) terminal on your battery. To uncover the remote positive (+) terminal, lift the red plastic cap.

5-3

6. 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 things you should know. Positive (+) will go to positive (+) and negative (-) will go to negative (-) or a metal engine part. Don’t connect (+) to (-), or you’ll get a short that would damage the battery and maybe other parts, too.

5-4

7. 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.

8.

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.

9.

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.

5-5

13. Remove the cables in reverse order to prevent

electrical shorting. Take care that they don’t touch each other or any other metal. A. Heavy Metal Engine Part B. Good Battery C. Dead Battery

10. Attach the cable at least 18 inches (45 cm) away

from the dead battery, but not near engine parts that move. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less.

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

the engine for a while.

12. Try to start the vehicle with the dead battery. If it

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

5-6

Towing Your Vehicle

Try to have a GM dealer or a professional towing service tow your Pontiac. The usual towing equipment is: A. Sling-type Tow Truck B. Wheel-lift Tow Truck C. Car Carrier

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 cannot be towed from the front or rear with sling-type equipment. 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.

~-

5-7

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 (N) 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 35 mph (55 km/h) or farther than 50 miles (80 km) or your transaxle will be damaged. If these limits must be exceeded, then the front wheels have to be supported on a dolly.

5-8

Front Towing Hookups

Attach T-hook chains in front of the wheels into the side slots of the cradle on both sides.

5-9

NOTICE: Do not tow with sling-type equipment or fascialfog lamp damage will occur. Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle to ground or vehicle to wheel-lift equipment. To help avoid damage, install a towing dolly and raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment. Do not attach winch cables or J-hooks to suspension components when using car carrier equipment. Always use T-hooks inserted in the T-hook slots.

Use wheel lift or car carrier equipment. Additional ramping may be required for car carrier equipment. Use safety chains and wheel straps.

5-10

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

Rear Towing Hookups

Attach T-hook chains into the slotted holes in the bottom of the floor pan support rails just ahead of the rear wheels on both sides.

5-11

NOTICE: Do not tow with sling-type equipment or the rear bumper valance will be damaged. Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle to ground or vehicle to wheel-lift equipment. To help avoid damage, install a towing dolly and raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment. Do not attach winch cables or J-hooks to suspension components when using car carrier equipment. Always use T-hooks inserted in the T-hook slots.

Use wheel lift or car carrier equipment. Additional ramping may be required for car carrier equipment. Use safety chains and wheel straps.

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

5-12

Engine Overheating You will find a coolant temperature gage and a warning light about a hot engine on your instrument panel. See “Engine Coolant Temperature Gage” and “Engine Coolant Temperature Warning Light” in the Index. You also have a low coolant light on your instrument panel. See “Low Coolant Light” in the Index. If Steam Is Coming From Your Engine

NOTICE: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty.

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.

5-13

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 NEUTRAL (N);

otherwise, shift to the highest gear while driving -- DRIVE (D) or THIRD (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 the warning stops. But then, if you still have the warning, turn ofSthe 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.

5-14

3.1L L82 (Code M) Engine

When you decide it’s safe to lift the hood, here’s what you’ll see: A. Coolant Recovery Tank B. Radiator Pressure Cap C. Electric Engine Fans

3.4L L27 (Code X) Engine

The coolant level should be at or above the COLD mark. 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.

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

5-15

How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at the COLD mark, 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.)

NOTICE: Engine damage from runmng your engine without coolant isn’t covered by your warranty.

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

5-16

NOTICE: In cold weather, water can kreeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant.

When the coolant in the coolant recovery tank is at the COLD mark, 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.

5-17

5-18

How to Add Coolant to the Radiator

NOTICE: Your engine has a specific radiator fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged.

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. TU^ 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.

5-19

3. After the engine cools, open the coolant air bleed

valve.

3.1L L82 (Code M) Engine

3.1L V6 (VIN Code M): There are two bleed valves. One is located on the thermostat housing. The other is located on the thermostat bypass tube.

3.4L LQl (Code X) Engine

3.4L V6 (VIN Code X): There are two bleed valves. They are located on the thermostat housing and heater inlet pipe.

5-20

Fill the radiator with the proper mix, up to the base of the filler neck, If you see a stream of coolant coming fi-om an air bleed valve, close the valve. Otherwise, close the valves after the radiatur is filled.

5. Rinse or wipe any spilled coolant from the engine

and compartment.

6. Then fill the coolant recovery tank to the COLD

mark.

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

leave the radiator pressure cap off,

5-21

10. Then replace the

pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure the arrows on the pressure cap line up like this.

11. Check the coolant in the recovery tank. The level in

the coolant recovery tank should be at mark when the engine is hot or at the COLD mark when the engine is cold.

the HOT

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

9. 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 base of the filler neck.

5-22

If a Tire Goes Flat

Changing a Flat Tire

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.

Turn the wing nut counterclockwise and remove it. Then lift off the spacer and remove the spare tire.

5-24

If there is a wheel cover, loosen the plastic nut caps with the wheel wrench. They won’t come off. Then, using the flat end of the wheel wrench, pry along the edge of the cover until it comes off. Be careful; the edges may be sharp. Don’t try to remove the cover with your bare hands.

Turn the nut holding the jack and wrench counterclockwise and remove it. Then remove the jack and wrench.

If your vehicle has wheel nut caps, remove them using the wheel wrench.

5-25

Turn the jack handle clockwise to raise the jack lift head a few inches.

Position the jack under the vehicle and raise the jack lift head until it fits firmly into the notch in the vehicle’s frame nearest the flat tire.

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

Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground for the spare tire to fit under the vehicle. Remove all wheel nuts and take off the flat tire.

5-27

Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. 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 against the hub.

Lower the vehicle by turning the jack handle counterclockwise, Lower the jack completely.

Tighten the wheel nuts firmly in a crisscross sequence as shown.

5-29

Don’t try to put the 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:

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

After you’ve put the compact spare tire on your vehicle, you’ll need to store the flat tire in your trunk. Use the following procedure to secure the flat tire in the trunk. Put the flat tire in the trunk so the side that faces out when it is on the vehicle is facing down. The full-size tire will not fit down into the well. Place it SO the front is in the well and the rear is out of the well.

Put the bolt through one of the wheel nut holes, the retainer over the bolt, then the spacer and nut next to the cover as far forward as possible.

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: 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.

Don’t use your compact spare on some other vehicle. And don’t mix your compact spare or wh.ee1 with other wheels or tires. They won’t fit. Keep your spare and its wheel together.

NOTICE: Tire chains won’t fit your compact spare. Using them will damage your vehicle and destroy the chains too. Don’t use tire chains on your compact spare.

5-32

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

NOTICE: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle.

For information about using tire chains on your vehicle. see “Tire Chains” in the Index. Rocking your vehicle to get it out: First, turn your steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as 1.ittle as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Pontiac Service Manual. It tells you much more about how to service your Pontiac than this manual can. To order the proper service manual, see “Service Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Pontiac” 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.

6-2

I NOTICE:

If you try to do your own service work without knowing enough about it, your vehicle could be damaged.

Fuel Use regular unleaded gasoline rated at 87 octane or higher. It should meet specifications ASTM D4814 i.n the United States and CGSB 3 5 9 2 in Canada. These hels should have the proper additives, so you should not have to add anything to the fuel. h the United States and Canada, it’s easy to be sure you get the right kind of gasoline (unlea.ded). 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. Lf you’re using fuel rated at 87 octane or higher and you still hear heavy hocking, 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 dan’t have to buy a higher octane fuel to get rid of pinmg. It’s the heavy, constant knock that means you have a problem.

What about gasoline with blending materials that contain oxygen (oxygenates), 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 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 these

6-3

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 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 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 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.

in those

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. 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).

When you put the cap back on, turn it to the right until you hear at least three clicks.

I NOTICE:

If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit or have proper venting, and your fuel tank and emissions system might be damaged.

Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Pontiac” in the Index.

If the LOW OIL LEVEL 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 Level Light” in the Index.

I 1

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.

3.1L L82 (Code M) Engine

The engine oil dipstick handle is the yellow loop near the front of the engine. 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.

3.4L LQ1 (Code X) Engine

TQ Check Engine Oi 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 upper mark, then you’ll need to add some oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

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

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.

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

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

What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

When to Change Engine OiI 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.

0 Most trips include extensive idling (such as frequent

driving in stop and go traffic). Most trips are through dusty areas. You frequently tow a trailer or use a carrier on top of your vehicle.

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°F (-18°C) or colder. If your vehicle has this option, see “Engine Coolant Heater” in the Index.

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

~~~

NOTICE: If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.

6-16

Wait at least 30 minutes before checking the transaxle fluid level if you have been driving: 0 When outside temperatures are above 90°F (32°C).

At high speed for quite a while. In heavy traffic -- especially in hot weather. While pulling a trailer.

To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). Get the vehicle warmed up by driving about when outside temperatures are above 50°F (10°C). If it's colder than 50°F ( 1O"C), you may have to drive longer. To check the fluid level

15 miles (24 km)

Park your vehicle on a level place. Keep the engine running. With the parking brake applied, place the shift lever in PARK (P). With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). Let the engine run at idle for three to five minutes.

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

3.1L L82 (Code M) Engine 3.4L LQl (Code X) Engine

1. The transaxle fluid dipstick handle is the red loop

near the back of the engine. 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.

6-17

How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids and Lubricants” in the Index. If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick. 1. Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the

dipstick hole to bring it to the proper level.

It doesn’t take much fluid, generally less than a pint (OSL). Don’t overfiZ1. We recommend you use only fluid labeled DEXRON@-111, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON@-III is not covered by your new vehicle warranty.

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

3.1L L82 (Code M) Engine 3.4L LQ 1 (Code X) Engine

3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the cross-hatched area.

4. If the fluid level is in the acceptable range, push the

dipstick back in all the way.

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°C). Give boiling protection up to 262°F (128 “C).

0 Protect against rust and corrosion.

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 flush and refill. If you use this mixture, you don’t need to add anything else.

I 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.

6-19

Adding Coolant

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.

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

Radiator Pressure Cap

Power Steering Fluid

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

When you replace your radiator pressure cap, an A@ 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.

6-22

3.1L L82 (Code M) Engine 3.4L LQl (Code X) Engine How To Check Power Steering Fluid When the engine compartment is cool, unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.

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 fluid can cause leaks and damage hoses and seals.

A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

NOTICE:

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only 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.

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

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

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

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.

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

When your brake fluid falls to a low level, your brake warning light will come on. See “Brake System Warning Light” in the Index.

6-25

Brake Wear Your Pontiac has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

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

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. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you 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 dnve 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.

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 Pontiac 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.

Headlamp Aiming

This section only applies to two-door Pontiacs. If you have a four-door Pontiac, see your dealer when your headlamp aim needs to be checked or adjusted.

Your vehicle has the 55 x 135 mini-quad headlamp system. These headlamps have horizontal and vertical aim indicators. The aim has been pre-set at the factory and should need no further adjustment. If your vehicle is damaged in an accident and the headlamp aim seems to be affected, see your Pontiac dealer. Headlamps on damaged vehicles may require recalibration of the horizontal aim by your Pontiac dealer. To check the aim, the vehicle should be properly prepared as follows:

The vehicle must have all four tires on a perfectly level surface. The vehicle should not have any snow, ice, or mud attached to it. There should not be any cargo or loading of vehicle, except it should have a full tank of gas and one person or 160 pounds (75 kg) on the driver’s seat. Tires should be properly inflated.

I NOTICE:

To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts.

State inspection stations will allow a vertical reading of plus 0.76 degrees or minus 0.76 degrees for the center of the bubble.

~~

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 regularrotation 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. I n

NOTICE: (Continued) If your tires have too much air (overinflation), you can get: 0 Unusual wear Bad handling Rough ride

0 Needless damage from road hazards.

P en to Check Check your tires once a month or more. ,Don’t forget your compact spare tire. It should be at 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 out dirt and moisture.

6-48

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

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.

.. .

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.

0 The tire has a puncture, cut, or other damage that

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

6-49

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 an “MS” (for mud and snow). If you ever replace your tires with those not having 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.

6-50

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 conltions 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. 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 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 thatsis 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. 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.

Used Replacement Wheels

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.

6-53

! i Tire Chains

NOTICE: If your Pontiac has P215/60R16 or P225/60R16 size tires, don’t use tire chains; they can damage your vehicle. If you have other tires, use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires. Install them on the front tires and tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.

Alcohol Laundry Soap 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.

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

Using Foam-mpe 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
