How to Reset the GM Oil Life System The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE OIL SOON light being turned on, reset the system. To reset the GM Oil Life System after the oil has been changed, use one of the following two procedures: Using the Driver Information Center (DIC) 1. With the ignition key in RUN but the engine off, fully push and release the accelerator pedal slowly three times within five seconds. 2. If the CHANGE OIL SOON light flashes, the system is resetting. 3. Turn the key to OFF after the light stops flashing, then start the vehicle. If the CHANGE OIL SOON light comes back on, the engine oil life monitor has not reset. Repeat the procedure. Using the Trip Computer (If Equipped) 1. Press the MODE button until the light appears lit next to OIL LIFE. 2. Press and hold the RESET button for three seconds. The oil life percentage should change to 100% t t What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Don't let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. t 6-19
