How to Reset the CHANGE ENGINE OIL Message The GM Oil Life SystemTM calculates when to change your engine oil and filter based onvehicle 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 ENGINE OIL message in theDriver Information Center (DIC) being turned on, reset the system. After the oil has been changed, the CHANGE ENGINE OIL message must be reset. To reset the message, do the following: 1. Turn the key to the "ON" position without starting the engine. 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 the INFO button on the Driver Information Center (DIC) until ENGINE OIL LIFE is displayed. 3. Press and hold the INFO RESET button until 100% ENGINE OIL LIFE is displayed. This resets the oil life indicator. The percentage of oil life remaining may be checked at any time by pressing the INFO button until ENGINE OIL LIFE is displayed on the DIC. For more information on the oil life indicator, see Oil Life indicator on page 3-79. 5-18
