CHANGE ENGINE OIL LIGHT RESET - PROCEDURE 1

1. The CHANGE OIL SOON (or CHANGE ENGINE OIL) light is illuminated when its time to change engine oil, usually between 3000 and 10,000 miles since last oil change.

2. To reset oil life monitor, turn ignition switch to RUN position, with engine off. Cycle accelerator pedal from closed throttle to Wide Open Throttle (WOT) 3 times within 5 seconds. CHANGE OIL SOON light will flash for 2 seconds when system is reset.

3. If CHANGE OIL SOON light comes on and stays on for 5 seconds, the system did not reset. Repeat reset procedures.
