Oil life & reset procedures
Engine oil life system reset
Before you start
- Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change.
Steps
- Using the DIC controls on the right side of the steering wheel, display REMAINING OIL LIFE on the DIC. See Driver Information Center (DIC) 0 134. When remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display.
- Press SEL on the DIC controls and hold SEL down for a few seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%.
You’ll know it worked: If the CHANGE ENGINE OIL SOON message is not on, the system is reset.
