Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the Engine Oil Life System: 1. Display the OIL LIFE REMAINING on the DIC. If your vehicle does not have DIC buttons, the vehicle must be in PARK (P) to access this display. See DIC Operation and Displays (With DIC Buttons) on page 3-56 or DIC Operation and Displays (Without DIC Buttons) on page 3-61. 2. Press and hold the SET/RESET button on the DIC, or the trip odometer reset stem if your vehicle does not have DIC buttons, for more than five seconds. The oil life will change to 100%. If the CHANGE ENGINE OIL SOON message comes back on when you start your vehicle, the Engine Oil Life System has not reset. Repeat the procedure. 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 used oil, ask your dealer/retailer, a service station, or a local recycling center for help. Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-14 for the location of the engine air cleaner/filter and the air filter restriction indicator, if the vehicle has one. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not 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. 5-19
