How to Reset the Change Engine Oil Message 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 engine oil message being turned on, reset the system. 1. With the ignition key in RUN but the engine off, repeatedly push the tripheset button until OIL is displayed on the Driver Information Center (DIC). 2. Once OIL is displayed, push and hold the tripheset button for five seconds. The number will disappear and be replaced by 100 (indicating 100% oil life remaining). 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. 3. Turn the key to OFF. If the change engine oil message comes back on, the engine oil life monitor has not reset. Repeat the procedure. Engine Air CleanerlFilter The engine air cleaner/filter is located at the front of the engine compartment, on the driver's side of the vehicle, under the engine coolant reservoir. See Engine Compartment Overview on page5-12 for more information on location. 5-18
