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 in the Driver Information Center (DIC) being turned on, reset the system. After the oil has been changed, the CHANGE ENGINE OIL SOON message must be reset: 1. Turn the key to the ON/RUN position without starting the engine. 2. Press the INFO button on the Driver Information Center (DIC) until OIL LIFE REMAINING is displayed. See DIC Operation and Displays on page 4-62. 3. Press and hold the INFO RESET button until 100% is displayed. This resets the oil life indicator. 4. Turn the key to LOCK/OFF. If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure. 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. Engine Air Cleaner/Filter See Engine Compartment Overview on page 6-12 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance on page 7-3 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. 6-17
