After changing the engine oil, the system must be reset as follows: 1. Turn the ignition to RUN, with the engine off. 2. Press the information and reset buttons on the DIC at the same time to enter the personalization menu. See DIC Vehicle Personalization on page 182. 3. Press the information button to scroll through the available personalization menu modes until the DIC display shows OIL-LIFE RESET. 4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you the system has been reset. 5. Turn the key to LOCK. If the CHANGE OIL SOON message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the reset procedure. 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. 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. 293
