The maintenance instructions contained in this Maintenance Schedule are based on the assumption that the vehicle will be used as designed:

The services shown in this schedule up to 166 000 km (100,000 mi) should be performed after 166 000 km (100,000 mi) at the same intervals. The services shown in this schedule to be performed at 240 000 km (150,000 mi) should be performed after 240 000 km (150,000 mi) at the same intervals.

For explanations of the maintenance inspections and services included in this Maintenance Schedule, refer to Explanation of Scheduled Services .

For additional maintenance inspections and services which are not included in this Maintenance Schedule, refer to Periodic Maintenance Inspection .

[Dagger] The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emissions warranty or limit recall liability prior to the completion of the vehicle's useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

Change the engine oil and filter as indicated by the GM Oil Life System ™ (or every 12 months, whichever occurs first). Reset the system, refer to GM Oil Life System Resetting .

This vehicle is equipped with an engine oil monitor. The engine oil monitor will indicate when to change the engine oil -- usually between 5 000 km (3,000 mi) and 25 000 km (15,000 mi) since the last oil change. Under severe conditions, the CHANGE OIL message may be displayed before 5 000 km (3,000 mi).

The vehicle MUST NOT be driven more than 25 000 km (15,000 mi) or 12 months without an oil and filter change. Use engine oil meeting the GM Standard GM4718M.

The engine oil monitor will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 mi) or sooner if the CHANGE OIL message is displayed. Be sure to reset the engine oil monitor when the oil has been changed. For the engine oil monitor resetting procedure, refer to GM Oil Life System Resetting .

25 000 km (15,000 mi)

Inspect the air cleaner filter if the vehicle is driven in dusty conditions. Replace the filter if necessary.

This is an emission control service. Refer to footnote [Dagger].

50 000 km (30,000 mi)

Replace the air cleaner filter. This is an emission control service. Refer to footnote [Dagger].

75 000 km (45,000 mi)

Inspect the air cleaner filter if the vehicle is driven in dusty conditions. Replace the filter if necessary.

This is an emission control service. Refer to footnote [Dagger].

83 000 km (50,000 mi)

Change the automatic transmission fluid and filter if the vehicle is mainly driven under one or more of these conditions:

If the vehicle is not used under any of these conditions, change the fluid and filter at 166 000 km (100,000 mi).

Manual transmission fluid does not require change.

100 000 km (60,000 mi)

125 000 km (75,000 mi)

Inspect the air cleaner filter if the vehicle is driven in dusty conditions. Replace the filter if necessary.

This is an emission control service. Refer to footnote [Dagger].

150 000 km (90,000 mi)

Replace the air cleaner filter. This is an emission control service. Refer to footnote [Dagger].

166 000 km (100,000 mi)

If the vehicle has not been used under any of the severe conditions listed previously and, therefore, has not had the automatic transmission fluid and filter changed, change both the fluid and filter.

Manual transmission fluid does not require change.

240 000 km (150,000 mi)

Drain, flush and refill the cooling system (or every 60 months since the last cooling system service, whichever occurs first). For information on the proper coolant to use, refer to Fluid and Lubricant Recommendations .
