GM Oil Life System Description
GM OIL LIFE SYSTEMIf the vehicle is equipped with a GM Oil Life System, this feature will let you know when to change the oil and filter - usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km).
Never drive the vehicle more than 12 500 km (7,500 miles) or 12 months, (whichever occurs first), without an oil change. The GM Oil Life System 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 miles) or sooner if the "CHANGE OIL" or "CHANGE OIL SOON" message is displayed.
To reset the GM Oil Life System, refer to Service Reminder Indicators / Oil Change Reminder Lamp.
