GM Oil Life System™ Press the reset stem until OIL LIFE appears (flashing) on the display. The GM Oil Life System™ shows an estimate of the oil's remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions. Always reset the engine oil life after an oil change. To reset the oil life system press and hold the reset stem while OIL LIFE is displayed. The system will reset and a beep will sound. The DIC does not replace the need to maintain your vehicle as recommended in the Maintenance Schedule in this manual. The oil change reminder will not detect dusty conditions or engine malfunctions that may affect the oil. Also, the oil change reminder does not measure how much oil you have in your engine. So, be sure to check your oil level often. See Engine Oil on page 5-13 for more information.
