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.
WHAT KIND OF ENGINE OIL TO USE
Look for two things:
1. 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.
2. 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 engine oil additives. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all that is needed for good performance and engine protection.
TIRE AND WHEEL INSPECTION AND ROTATION
The vehicle tires should be inspected regularly for wear. Any time you notice unusual wear, rotate the tires as soon as possible and test the wheel alignment. Also inspect 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. Refer to Scheduled Maintenance for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here. After the tires have been rotated, adjust the front and rear inflation pressures Refer to Tire Placard. Vehicles equipped with the Tire Pressure Monitor (TPM) system will need to have the sensors reset after a tire rotation is performed. A special tool is needed to reset the sensor identification codes. Ensure that all wheel nuts are properly tightened.
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.
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. Refer to Brake Pad Inspection in Disc Brakes. 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.
