Maintenance Schedule Engine Oil Change Intervals

This vehicle is equipped with an engine oil life monitor. The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the CHANGE OIL message may be displayed before 5 000 km (3,000 miles).

The vehicle MUST NOT be driven more than 16 000 km (10,000 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 message is displayed.
