If your vehicle has the optional DIC, do the following: 1. Turn the ignition to ON, with the engine off. 2. Press the MODE button until the DIC reads OIL LIFE LEFT/HOLD SET TO RESET. 3. Press and hold the SET button until 100% is displayed. You will hear three chimes and the CHANGE ENGINE OIL message will go off. 4. Turn the key to OFF. If the CHANGE ENGINE OIL 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 your used oil, ask your dealer, a service station or a local recycling center for help. Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-12 for the location of the engine air cleaner/filter. What to Do with Used Oil Used engine oil contains certain elements that may 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. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at every oil change and replace it at the first oil change after 25,000 miles (40 000 km). See Scheduled Maintenance on page 6-4 for more information. 5-19
