This vehicle has an engine oil life monitor. 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 mi) and 12 500 km (7,500 mi) since the last oil change. Under severe conditions, the indicator may come on before 5 000 km (3,000 mi).
Vehicle should not be driven more than 12 500 km (7,500 mi) or 12 months without an oil and oil filter change. The system will not detect dust in the oil. So if the vehicle is driven in a dusty area, be sure to change the oil and oil filter every 5 000 km (3,000 mi) or sooner if the CHANGE OIL SOON indicator comes on. Reset the system when the oil has been changed.
