Vehicle Care

What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not 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 dispose of 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 threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

Automatic Transmission Fluid How to Check Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer/retailer service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, you should have this done at your dealer/ retailer service department.

Contact your dealer/retailer for additional information or the procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 12-12. Change the fluid and filter at the intervals listed in Scheduled Maintenance on page 10-2, and be sure to use the fluid listed in Recommended Fluids and Lubricants on page 10-7.

Vehicle Care

9-15

How to Check and Add Fluid Visually check the brake/clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The brake/hydraulic clutch fluid system should be closed and sealed. Do not remove the cap to check the fluid level or to top-off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.

Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer/ retailer service department and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 10-7 for the proper fluid to use.

Hydraulic Clutch It is not necessary to regularly check brake/clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

When to Check and What to Use

The brake/hydraulic clutch fluid reservoir cap has this symbol on it. The common hydraulic clutch and brake master cylinder fluid reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 9-6 for reservoir location.

Vehicle Care

Engine Air Cleaner/Filter See Engine Compartment Overview on page 9-6 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (80 000 km) interval. See “Schedule Maintenance” in Service and Maintenance for more information. If driving in dusty/dirty conditions, inspect the filter at each engine oil change.

How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. To inspect or replace the engine air cleaner/filter: 1. Open the hood. See Hood on

page 9-5.

2. Locate the air filter housing

on the front of the driver side of the engine compartment. See Engine Compartment Overview on page 9-6.

{ WARNING

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

If the coolant inside the coolant recovery bottle is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. The coolant level should be between the MIN and MAX lines. If it is not, you may have a leak at the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system.

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

If there seems to be no leak, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, the fans should be running. If it is not, your vehicle needs service. Turn off the engine.

What to Use

{ WARNING

Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant.

Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 miles) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle.

Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for five years or 240 000 km (150,000 miles), whichever occurs first. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 9-24.

Vehicle Care

9-19

Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant. If using this mixture, nothing else needs to be added. This mixture: • Gives freezing protection down to −37°C (−34°F), outside temperature.

• Gives boiling protection up

to 129°C (265°F), engine temperature.

• Protects against rust and

corrosion.

• Will not damage aluminum parts. • Helps keep the proper engine

temperature.

If an improper coolant

Notice: mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts.

Vehicle Care

Checking Coolant The vehicle must be on a level surface when checking the coolant level. Check coolant as follows: 1. Turn the ignition OFF. 2. Locate the coolant recovery

bottle. See Engine Compartment Overview on page 9-6.

3. Turn the coolant dipstick cap counterclockwise and slowly pull out the dipstick.

How to Add Coolant to the Coolant Recovery Bottle

{ WARNING

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.

If an improper coolant

Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged. Notice: mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts.

4. There are maximum and minimum markings on the dipstick. When the engine is cold, the coolant level should be at or above the MIN mark on the dipstick. After the vehicle has been driven and the engine is at normal operating temperature, the level should be somewhere between half full and the maximum mark. If the coolant level is correct, replace the dipstick and turn the cap clockwise to secure.

{ WARNING

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Wait for the cooling system and surge tank pressure cap to cool if you ever have to turn the pressure cap.

If coolant is needed, add the proper mixture directly to the radiator, but be sure the cooling system is cool before this is done.

Vehicle Care

Engine Overheating The vehicle has an indicator to warn of engine overheating. There is an engine coolant temperature warning light on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 4-14. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 12-6. If you do decide to lift the hood, make sure the vehicle is parked on a level surface.

Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: fire because of being driven with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty.

If the engine catches

If Steam Is Coming From The Engine Compartment { WARNING

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

If No Steam Is Coming From The Engine Compartment If an engine overheat warning is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle: • Climbs a long hill on a hot day. • Stops after high-speed driving. • Idles for long periods in traffic. • Tows a trailer. If the overheat warning is displayed with no sign of steam: 1. Turn the air off. 2. Turn the heater on to the highest

temperature and to the highest fan speed. Open the windows as necessary.

3.

In heavy traffic, let the engine idle in N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the engine idle.

If the temperature overheat gage is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle distance from the car in front of you. If the warning does not come back on, continue to drive normally. If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see “Overheated Engine Protection Operating Mode” later in this section.

Power Steering Fluid

The power steering fluid reservoir is located under the engine cover on the driver side toward the front of the engine compartment. See Engine Compartment Overview on page 9-6. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

9-26

Vehicle Care

How to Check Power Steering Fluid Check the level after the vehicle has been driven for at least twenty minutes so the fluid is warm. To check the power steering fluid: 1. Turn the ignition key to

LOCK/OFF and let the engine compartment cool down.

2. Remove the engine cover. Refer

to Engine Cover on page 9-9.

3. Wipe the cap and the top of the

reservoir clean.

4. Turn the cap counterclockwise

and pull it straight up.

5. Wipe the dipstick with a

clean rag.

6. Replace the cap and completely

tighten it.

7. Remove the cap again and look at the fluid level on the dipstick.

When the engine is hot, the level should be at the hot MAX level. When the engine is cold, the fluid level should be between MIN and MAX on the dipstick.

What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 10-7. Always use the proper fluid.

Washer Fluid What to Use When windshield washer fluid is needed, be sure to read the manufacturer’s instructions before use. If operating vehicle in an area where the temperature can fall below freezing, use a fluid that has sufficient protection against freezing.

Adding Washer Fluid

Open the cap with the washer symbol on it. Add washer fluid until the reservoir is full. See Engine Compartment Overview on page 9-6
for reservoir location.

Notice: (cid:129) When using concentrated

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

(cid:129) Do not 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 does not clean as well as washer fluid. Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.

(cid:129) Do not use engine coolant

(antifreeze) in your windshield washer. It can damage the vehicle’s windshield washer system and paint.

Brakes This vehicle has 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 can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.

{ WARNING

The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident. When the brake wear warning sound is heard, have the vehicle serviced.

Notice: Continuing to drive with worn-out brake pads could result in costly brake repair.

Vehicle Care

9-27

Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications on page 11-2. Brake linings should always be replaced as complete axle sets.

Brake Pedal Travel See your dealer/retailer 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 that brake service might be required.

(cid:129) 9-28

Vehicle Care

Brake Adjustment Every time the brakes are applied, with or without the vehicle moving, the brakes adjust for wear.

Replacing Brake System Parts The braking system on a 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. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced, be sure to get new, approved replacement parts. If this is not done, the brakes might not work properly. For example, installing disc brake pads that are wrong for the vehicle, can change the balance between the front and rear brakes —for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.

Brake Fluid

The brake/clutch master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 9-6 for the location of the reservoir. There are only two reasons why the fluid level in the reservoir might go down: • The fluid level goes down

because of normal brake lining wear. When new linings are installed, the fluid level goes back up.

• A fluid leak in the brake/clutch

hydraulic system can also cause a low fluid level. Have the brake/clutch hydraulic system fixed, since a leak means that sooner or later the brakes and/or clutch will not work well.

Do not top off the brake/clutch fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake/clutch hydraulic system.

{ WARNING

If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake/clutch hydraulic system.

When the brake/clutch fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 4-22.

What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 10-7. Always clean the brake/clutch fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.

{ WARNING

With the wrong kind of fluid in the brake/clutch hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake/clutch fluid.

Notice: (cid:129) Using the wrong fluid can badly damage brake/clutch hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid. If brake fluid is spilled on the vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately.

Vehicle Care

Vehicle Storage

{ WARNING

Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting on page 9-84 for tips on working around a battery without getting hurt.

Infrequent Usage: If the vehicle is driven infrequently, remove the black, negative (−) cable from the battery. This helps keep the battery from running down.

Extended Storage: For extended storage of the vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time.

Rear Axle When to Check Lubricant It is not necessary to regularly check rear axle fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.

Headlamp Aiming The headlamp aiming system has been preset at the factory. If the vehicle is damaged in an accident, the aim of the headlamps may be affected and adjustment may be necessary. It is recommended that a dealer/retailer adjust the headlamps. To re-aim the headlamps yourself, use the following procedure. The vehicle should be properly prepared as follows: • The vehicle should be placed so the headlamps are 7.6 m (25 ft) from a light colored wall.

• The vehicle must have all four tires on a level surface which is level all the way to the wall.

• The vehicle should be placed so it is perpendicular to the wall or other flat surface.

• The vehicle should not have any

snow, ice, or mud on it.

• The vehicle should be fully

assembled and all other work stopped while headlamp aiming is being performed.

• The vehicle should be normally loaded with a full tank of fuel and one person or 75 kg (160 lbs) sitting on the driver’s seat.

• Tires should be properly inflated. Headlamp aiming is done with the vehicle’s low-beam headlamps. The high-beam headlamps will be correctly aimed if the low-beam headlamps are aimed properly.

To adjust the vertical aim: 1. Open the hood. See Hood on page 9-5 for more information.

Electrical System Electrical System Overload The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems. Fuses and circuit breakers protect the following in the vehicle: • Headlamp Wiring • Windshield Wiper Motor • Power Windows and other Power

Accessories

9-42

Vehicle Care

Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.

Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice, may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible. To identify and check fuses, circuit breakers, and relays, see Engine Compartment Fuse Block on page 9-42, Instrument Panel Fuse Block on page 9-45, and Rear Compartment Fuse Block on page 9-46.

Engine Compartment Fuse Block

To remove the hinged fuse block cover, press the clip at the front of the cover, and swing it up. Notice: Spilling liquid on any electrical components on the vehicle may damage it. Always keep the covers on any electrical component.

Wheels and Tires Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your vehicle Warranty booklet for details. For additional information refer to the tire manufacturer. { WARNING

Poorly maintained and improperly used tires are dangerous.

• Overloading your tires can

cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Vehicle Load Limits on page 8-12.

(Continued)

WARNING (Continued)

• 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. See Tire Pressure on page 9-54.

• 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.

Winter Tires If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. All season tires provide good overall performance on most surfaces but they may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads. Winter tires, in general, are designed for increased traction on snow and ice covered roads. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After switching to winter tires, be alert for changes in vehicle handling and braking. See your dealer/retailer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires on page 9-63.

If you choose to use winter tires: • Use tires of the same brand and

tread type on all four wheel positions.

• Use only radial ply tires of the

same size, load range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire’s maximum speed capability.

Tire Sidewall Labeling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger vehicle tire and a compact spare tire sidewall.

Passenger (P-Metric)

Tire Example

(A) Tire Size: The tire size is a combination of letters and numbers used to define a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section for more detail.

Vehicle Care

9-49

(B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards.

9-50

Vehicle Care

(D) Tire Identification Number (TIN): The letters and numbers following the DOT (Department of Transportation) code is the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of
