### Maintenance Schedule Intervals

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

### Maintenance Schedule Engine Oil Change Intervals

This vehicle is equipped with a GM Oil Life System™. The GM Oil Life System™ will show when to change the engine oil and oil filter. This will usually occur between 5 000 km (3 000 miles) and 12 500 km (7,500 miles) since the last oil change. Under severe conditions, the indicator may come on before 5 000 km (3 000 miles).

Never drive the vehicle more than 12 500 km (7 500 miles) or 12 months without an oil and oil filter change.

The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil and oil filter every 5 000 km (3 000 miles) or sooner if the CHANGE OIL SOON indicator comes on. Reset the Oil Life System when the oil and filter have been changed.
