If the system is ever reset accidentally, you must change the oil at 3,000 miles (5 000 km) since the last oil change. Remember to reset the oil life system whenever the oil is changed. If the CHANGE OIL message comes back on when you start the vehicle, the engine oil life system has not reset. Repeat the procedure. See DIC Warnings and Messages on page 3-38. How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change the oil prior to a CHANGE OIL message being turned on, reset the system. To reset the Engine Oil Life system: 1. With the engine off, turn the ignition to ON/RUN. 2. Press and release the stem in the lower center of the instrument cluster until the OIL LIFE message is displayed. 3. Once the alternating OIL LIFE and RESET messages appear, press and hold the stem until several beeps sound. This confirms that the oil life system has been reset. 4. Turn the key to LOCK/OFF. 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. 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. Recycle it by taking it to a place that collects used oil. 5-19
