EXPLANATION OF SCHEDULED SERVICESENGINE OIL
If the "LOW OIL LEVEL" message appears on the Driver Information Center (DIC), test the engine oil level right away. Although the driver should test the engine oil level regularly, this message is an added reminder.
ENGINE OIL TYPE
GM4718M Your vehicle's engine requires a special oil meeting GM Standard GM4718M. Oils meeting this standard may be identified as synthetic. However, not all synthetic oils will meet this GM standard. You should look for and use only an oil that meets GM Standard GM4718M.
NOTICE: If you use oils that do not have the GM4718M Standard designation, you can cause engine damage not covered by your warranty.
SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it is going to be 0°F (-18°C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.
Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).
You should look for this on the oil container, and use only those oils that are identified as meeting GM Standard GM4718M and have the starburst symbol on the front of the oil container.
Your vehicle's engine is filled at the factory with a Mobil 1 synthetic oil, which meets all requirements for your vehicle.
Substitute Engine Oil: When adding oil to maintain engine oil level, oil meeting GM Standard GM4718M may not be available. You can add substitute oil designated SAE 5W-30 with the starburst symbol at all temperatures. If temperatures are above 0°F (-18°C), you may substitute SAE 10W-30 with the starburst symbol. Substitute oil not meeting GM Standard GM4718M should not be used for an oil change.
ENGINE OIL ADDITIVES
Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection.
TIRE INSPECTION AND ROTATION
Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important.
Non-Directional Tires:
When rotating non-directional tires, always use the correct rotation pattern shown here.
Directional Tires:
If your vehicle has 215/45ZR17size tires, they are directional tires and must roll in a certain direction for the best overall performance. The direction is shown by an arrow on the tire sidewall. Because these tires are directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front on the same side of the vehicle.
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 and Loading Information label. Make certain that all wheel nuts are properly tightened.
CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.
ENGINE AIR CLEANER/FILTER
Inspect the air cleaner filter every oil change and replace at the first oil change after 40 000 km (25,000 mi).
AUTOMATIC TRANSAXLE FLUID
It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. Change both the fluid and filter every 83 000 km (50,000 mi) if the vehicle is mainly driven under one or more of these conditions:
^ In heavy city traffic where the outside temperature regularly reaches 32�C (90�F) or higher
^ In hilly or mountainous terrain
^ When doing frequent trailer towing
^ Uses such as found in taxi, police or delivery service
MANUAL TRANSMISSION FLUID
It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss.
HYDRAULIC CLUTCH
The hydraulic clutch linkage is self-adjusting. This system does not have its own reservoir. The reservoir receives fluid from the brake master cylinder reservoir.
COOLING SYSTEM
The cooling system is filled with DEX-COOL engine coolant. This coolant is designed to remain in the vehicle for 5 years or for 166 000 km (100,000 mi), whichever occurs first, if you add only DEX-COOL extended life coolant.
POWER STEERING FLUID
It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
WINDSHIELD WASHER FLUID
When adding windshield washer fluid, be sure to read the instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
BRAKE FLUID
Your brake master cylinder reservoir is filled with DOT-3 brake fluid.
There are only two reasons why the brake fluid level in the reservoir might go down:
^ 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 fluid may be leaking out of the brake system. If so, fix the brake system. Adding brake fluid will not correct a leak. If you add fluid when the linings are worn, then the reservoir will contain too much fluid when new brake linings are installed. You should add or remove brake fluid, as necessary, only when work is being done on the brake hydraulic system.
Inspect brake lines and hoses for proper hook-up binding, leaks, cracks or chafing. Inspect disc brake pads for wear. Inspect the rotors for poor surface condition. Inspect other brake system components, including brake calipers and the parking brake. Test the parking brake adjustment. The brakes may need to be inspected more often if the customer's driving habits or conditions result in frequent braking.
