Maintanence Schedule Engine Oil Change Intervals

This vehicle has an engine oil life monitor. The engine oil life monitor will show when to change the engine oil and oil filter. This will usually occur between 5 000 km (3,000 miles) and 12 500 km (7,500 miles) since the last oil change. Under severe conditions, the indicator may come on before 5 000 km (3,000 miles).

Never drive the vehicle more than 12 500 km (7,500 miles) or 12 months without an oil and oil filter change. The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil and oil filter every 5 000 km (3,000 miles) or sooner if the CHG OIL SOON indicator comes on. Reset the oil life monitor when the oil has been changed. Refer to Oil Life Monitor Resetting .
