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 the oil filter. This will usually occur between 5 000 km and 12 500 km since the last oil change. Under severe conditions, the indicator may come on before 5 000 km.

Do not drive the vehicle more than 12 500 km or 12 months without an oil change and an oil filter change. The system will not detect dust in the oil. If the vehicle is driven in a dusty area, change the oil and oil filter every 5 000 km, or sooner, if the CHANGE OIL SOON indicator turns on. Reset the Oil Life System when the oil and the filter have been changed.
