How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change your 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 OIL SOON message being turned on, reset the system. After changing the engine oil, the system must be reset: 1. Turn the ignition to ON/RUN, with the engine off. 2. Press the information and reset buttons on the Driver Information Center (DIC) at the same time to enter the personalization menu. See DIC Vehicle Personalization on page 3-56. 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/OFF. For vehicles with the 2.2L (VIN code V) or 2.4L (VIN code B) engines, you can also reset the system as follows: 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, then start the engine. If the CHANGE OIL SOON message comes back on when the vehicle is started, 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 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. 5-22
