Press the fuel information button until ENGINE OIL LIFE appears in 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 select button while ENGINE OIL LIFE is displayed. Be careful not to reset the engine oil life accidentally at any time other than when the oil has just been changed. It can't be reset accurately until the next oil change. The DIC does not replace the need to maintain your vehicle as recommended in the Maintenance Schedule in this manual. Also, the oil change reminder will not detect dusty conditions or engine malfunctions that may affect the oil. If you drive in dusty areas, change your oil after every 3,000 miles (5 000 km) or three months, whichever occurs first, unless the DIC instructs you to do so sooner. 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" in the Index. 2-94
