Twin Dual Cam 3.4L V6: Adding Automatic Transaxle Fluid

Service & Appearance Care

Manual Pransaxle Fluid When to Check: A good time to have it checked is when the engine oil is changed. However, the fluid in your manual transaxle does not require changing. How to Check: Because this operation can be a little difficult, you may choose to have this done at a Pontiac dealership service department. If you do it yourself, be sure to follow all the instructions here, or YQU could get a false reading on the dipstick.

’. 22%

00 little fluid can amage your transaxle. Too much an mean that some of the fluid ould come out and fall on hot ngine parts, starting a fire. Be ure to get an accurate reading if ou check your transaxle fluid.

The manual transaxle dipstick is located on the driver’s side near the rear of the transaxle case. Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transaxle is cool enough for you to rest your fingers on the transaxle case. Then, Follow These Steps: 1. Flip the handle up and then pull out the dipstick and clean it with a rag or paper towel.

2. Push it back in all the way and

remove it.

3. Check both sides of the dipstick and read the lower level. The fluid level must be between the ADD and FULL marks. (Note: Fluid may appear at the bottom of the dipstick even when the fluid level is several pints low.)

4. If the fluid is where it should be, push

the dipstick back in all the way.

How to Add Fluid: Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See the Index under Fluids G Lubricants. 1. Remove the dipstick by flipping the

handle up and then pulling the dipstick out.

2. Add fluid at the dipstick hole.

Add only enough fluid to bring the fluid level up to the FULL mark on the dipstick

3. Push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

Hydraulic Clutch Flujd The hydraulic clutch in your vehicle is self-adjusting. When to Check and What to Use: Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and what to add. See the Index under Owner Checks G Services and Fluids G Lubricants.

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 the Index under Engine Overheuling. The proper coolant for your Pontia’c will:

Give freezing protection do;wn to -34°F (-3 7 “C) . Give boiling protection up to 262°F (12S°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 dean water (preferably distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t darnage

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.

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mix of clean water and a Droner antifreeze.

Hydraulic Clutch Fluid (CONTJ How to Check The proper fluid should be added if the level does not reach the bottom of the diaphragm when it’s in place in the reservoir. See the instructions on the reservoir cap.

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.

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

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

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.

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

When the engine compartment is hot, the level should be at the H mark. When the engine compartment is cool, the level should be at the C mark.

What to Add: Refer to the Maintenance Schedule to determine what kind of fluid to use. See the Index under Fluids G Lubricants.

Windshield Washer Fluid To Add: Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the bottle is full.

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.

Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid. Your vehicle is equipped with either Standard Power Brakes or the Anti- Lock Brake 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 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 bralce linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

If you have too much bfake L fluid, it can spill on the

engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.

When your brake fluid falls to a low level, your brake warning light will come on. See the Index under Brake System Warning Light. What to Add: When you do need brake fluid, use only DOT-3 brake fluid-such as Delco Supreme ll@ (GM Part No. 1052535). Use new brake fluid from a sealed container only.

Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your 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 .

Baftery Every new Pontiac has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom@ battery. Get one that has the catalog number shown on the original battery’s label. Jump Starting For jump starting instructions, see the Index under Jump Starting.

Bulb Rephcement In this section you’ll find directions for changing the light bulbs in some of the lights on your Pontiac. You’ll also find directions for adjusting the alignment of the mini-quad headlights’ if you have this type. Be sure to read the directions before you begin to replace or adjust any lights. See the Index under Replacement Bulbs to find the type of bulb you need to use.

Vehicle Sforage If you’re not going to drive your vehicle for 25 days or more, take off the black, negative (-) cable from the battery. This will help keep your battery from running down.

A Batteries have acid that can - 1 burn you and gas that can explode. You can be badly hurt if you aren’t careful. See the Index under Jump Starting for tips on working around a battery without getting hurt.

Halogen Bulbs

Halogen bulbs have

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

Checking Aim of the Headlights @-DOOR MODELS) Your vehicle has the 55 x 135 mini- quad headlight system. These headlights have horizontal and vertical aim indicators. The aim has been preset at the factory and should need no further adjustment.

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. The horizontal indicator (A) should read 0 (zero).

Service lS Appearance C

Checking Aim of the Headlights (CONT.)

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

State inspection stations will allow a vertical reading of up plus .76 degrees or down minus .76 degrees €or the center of the bubble. It is recommended that the upper limit not exceed up plus .4 degrees for the center of the bubble. There may be an increased chance of being flashed if adjustment is much above up plus .4 degrees.

Aiming HeadJishts (2-DOOR MODELS) 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. The horizontal indicator should read 0 (zero).

1. Start with the horizontal (left and right) headlight aim. Don’t try to adjust the vertical (up and down) aim first.

2. Check the horizontal aim for each

headlight and adjust it as necessary. 3. Turn the horizontal aiming screw (A) until the pointer is lined up with the 0 (zero).

4. Now adjust the vertical aim. Check

the vertical aim for each headlight and adjust it as necessary.

5. Turn the Vertical aiming screw until the bubble in the level is centered at 0 (zero).

To Replace a Headlight (2-DOOR MODELS) Before replacing a headlight that does not light, check to make sure that the wiring connector is securely fastened to it. See the Index under Replacement Bulbs to check the size and type of headlight you need to use before you begin to replace the headlight. You must replace a headlight with one that is exactly the same. 1. Open the protective panel above the

Loading Your Vehicle Two labels on your vehicle show how much weight it may properly carry. The Tire-Loading Information label found on the inside of the trunk lid tells you the proper size, speed rating and recommended inflation pressures for the tires on your vehicle. It also gives you important information about the number of people that can be in your vehicle and the total weight that you can carry. This weight is called the Vehicle Capacity Weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. The other label is the Certification label, found on the rear edge of the driver’s door. It tells you the gross weight capacity of your vehicle, called the

4 Tires We don't make tires. Yo'ur 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. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

1 A, Poorly maintained armd improperly used tires are dangerous.

b Overloading your tires can cause overheating as a result of too much friction. YOU could have an &-out and a serious accident. See Loading Your Vehicle earlier in this section. Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more Likely to be cut, punctured, or broken by a sudden impact, such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

254

Inflation-Tire Pressure The Tire-Loading Information label which is on the inside of the trunk lid 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.

Don’t let anyone tell you th underinflation or overinflati all right. It’s not. If your tires d have enough air (underinflation

Too much heat

If your tires have too much air

When to Check: Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 ItPa). How to Check: Use a good quality pocket-type gage to check tire pressure. Simply loolting 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.

§ervice & Appearance Care

.............. ............. .... ............

Tire Inspection and Rotation To make your tires last longer, have them inspected and rotated at the mileages recommended in the Maintenance Schedule. See the Index under Scheduled Maintenance Services. Use this rotation pattern. If you don't have P245/50ZR16 size tires, use the rotation pattern shown above for your size tires.

If you have P245/510ZR16 size 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 tirles are directional, they should be rotated as shown in the example above. These tires should only be moved from front to rear and rear to front on the same side of the vehicle. After the tires have been rotated, adjust the front and rear inflation pressure as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See the Index under Wheel Nut Torque.

Rust or dirt on a wheel, or on

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

When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 2/32 inch (1.6 mm) or less of tread remaining. You need a new tire if:

You can see the indicators at three places around the tire. You can see cord or fabric showing through the tire’s rubber. 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.

Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way, your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by a “MS” (for mud and snow).

If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.

‘

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

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%) 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), €3, 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.

Wheel AIignrnenf 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.

Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Those grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades.

Wheel Replacement Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air out, replace it (except some aluminum wheels, which can sometimes be repaired). See your Pontiac dealer if any of these conditions exist. Your dealer will h o w the kind ~f 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.

Service & Appearance Care

Cleaning the Inside of Your Pontiac Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl 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. Here are some cleaning tips:

Always read the instructions on the cleaner label. Clean up stains as soon as you can- before they set. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.

Use solvent-type cleaners in a well- ventilated area only. If you use them, don’t saturate the stained area. If a ring forms after spot cleaning, clean the entire area immediately or it will set. Using Foam-Type Cleaner on Fabrrc 9 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 an air hose, a hair dryer or a heat lamp.

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 it, then:

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 an air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See the previous NOTICE.)

Special Cleaning Problems Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.

Carefully scrape off excess stain. Then follow the solvent-type instructions above. Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle seat fabric. They should be removed as soon as possible. Be careful, because the cleaner will dissolve them and may cause them to bleed.

Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood.

Carefully scrape off excess stain, then sponge the soiled area with cool water. If a stain remains, follow the foam- type instructions above. If an odor lingers after cleaning vomit or urine, treat the area with a water/ baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Finally, if needed, clean lightly with solvent-type cleaner.

Combination Stains: Like candy, ice cream, mayonnaise, chili sauce and unknown stains.

Carefully scrape off excess stain, then clean with cool water and allow to dY. If a stain remains, clean it with solvent-type cleaner.

Service & Appearance Care

Cleaning Vinyl or Leather Just use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and solvent-type vinyl/leather cleaner.

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 refle,ctions in the windshield and even make it difficult to see through the windshield under certain conditions.

Care of Safety Belts Keep belts clean and dry. CAUTION A Do not bleach or dye safety severely weaken them. In a crash they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami Powder@ (GM Part No. 105001 1). The windshield is clean if beads do not form when you rinse it with water. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn.

Cleaning the Outside of Your Pontiac The paint finish on pour vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (non-detergent) soaps. Don’t use cleaning agents 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 vehicle washes may cause water to enter your vehicle.

Service & Appearance Care

Finish Care Occasional waxing or mild polishing of your Pontiac may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See the Index under Appearance Care. ) Your Pontiac has a ‘‘basecoat/ clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat.

Aluminum Wheels (IF so EQUIPPED) Your aluminum wheels have a protective coating similar to the painted surface of your Pontiac. Don’t use strong soaps, chemicals, chrome polish, or other abrasive cleaners on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.

White Sidewall Tires Your Pontiac dealer has a GM White Sidewall Tire Cleaner. You can use a stiff brush with it. Weatherstrips These are places where glass or metal meets rubber. Silicone grease there will male them last longer, seal better, and not squeak. Apply silicone grease with a clean cloth at least every six months.

Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti- corrosion material to the parts repaired or replaced to restore corrosion protection. Foreign Material Calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, and other foreign matter can damage your vehicle’s finish if they remain on painted surfaces. Use cleaners that are marked safe for painted surfaces for these stains.

Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.

Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody vehicle washing system can do this for you.

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, Pontiac will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever comes first.

Vehicle Identification Number This is the legal identifier for your Pontiac. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration.

Engine Identification The eighth character in your VIN is the engine code for your GM engine. This code will help you identify your engine, specifications, and replacement parts in this section.

Service Pads Identification Label I Add-on EIecfrical Equipment

You'll find this label on your spare tire cover. It's very helpful if you ever need to order parts. On this label is:

Your VIN. Its model designation. Paint information. A list of all production options and special equipment.

Be sure that this label is not removed from the vehicle.

Spare fuses and a fuse puller are located in the glove box fuse block cover. Place the wide end of the fuse puller over the plastic end of the fuse. Squeeze the ends over the fuse and pull it out. To identify and check fuses, refer to the charts on the following pages.

Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.

Fuses & Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems. Some fuses are located in a fuse block in the glove box as shown above. To locate the fuse block, pull down the cover. See the diagram later in this section. Another set of fuses is located in the component center, under the instrument panel. Additional fuses are located in the underhood electrical centers on the right and left sides of the engine compartment. 2 7 0

Headlight Wiring The headlight wiring is protected by a circuit breaker in the component center. An electrical overload will cause the lights to go on and off, or in some cases to remain off. If this happens, have your headlight system checked right away.

Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed.

Power Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed.
