How to Reset the Oil Life System The GM Oil Life SystemTM 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 message being turned on, reset the system. Always reset the engine Oil Life System to 100% after every oil change. It will not reset itself. To reset the OIL LIFE reminder, do the following: 1. With the ignition on, press the SELECT right arrow on the DIC until you enter the OIL mode. The current OIL LIFE percentage will be displayed. 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 dispose of 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. 2. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show OIL LIFE XXX%. If OIL LIFE XXX% does not appear on the display after about five seconds, see your dealer for service. After you release the DIC RESET button, OIL LIFE 100% will appear on the display. 5-20
