Oil Change Reminder Lamp: Service and Repair
OIL LIFE MONITOR RESETTING
The engine oil life monitor will indicate when to change the engine oil - usually between 5,000 km (3,000 miles) and 12,500 km (7,500 miles) since
the last oil change. Under severe conditions, the CHANGE OIL SOON light may be displayed before 5,000 km (3,000 miles). The vehicle must not be
driven more than 12,500 km (7,500 miles) or 12 months without an oil change.
The engine oil life monitor will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5,000 km (3,000 miles)
or sooner if the CHANGE OIL SOON light is displayed.
PROCEDURE
1. Turn the ignition key to "ON" (engine off).
2. Push the accelerator pedal fully to the floor and slowly release three times within five seconds.
3. Turn the ignition "OFF".
If the "CHANGE ENGINE OIL" message comes back on, the monitor has not reset. Repeat the procedure.
