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 the oil is changed prior to a CHANGE ENGINE OIL SOON message being turned on, reset the system. To reset the CHANGE ENGINE OIL SOON message: 1. Turn the ignition key to ON/RUN with the engine off. 2. Fully press and release the accelerator pedal slowly three times within five seconds. 3. Turn the key to LOCK/OFF. If the message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure. If it still does not reset, see your dealer/retailer for service. 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
