Oil Life The GM Oil Life SystemTMis the only function accessible in the OIL mode. Engine oil life is displayed in a reading such as the following: OIL LIFE 30% This is 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. When the remaining oil life is low, the system will alert you with this message: CHANGE OIL SOON Always reset the OIL LIFE reminder after an oil change. To reset the oil life system, see "How to Reset the Oil Life System" under Engine Oil on page 5-75. Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the 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 on page 5- 15. 3-48
