When the CHANGE ENGINE OIL

SOON message displays, have the engine oil and filter changed within the next 1 000 km/600 mi. If driven under the best conditions, the engine oil life system may not indicate the need for vehicle service for up to a year. The engine oil and

filter must be changed at least once a year and the oil life system must be reset. Your trained dealer technician can perform this work.

If the engine oil life system is reset accidentally, service the vehicle within 5 000 km/3,000 mi since the last service. Reset the oil life system when the oil is changed.

See Engine Oil Life System 0 346.

The passenger compartment air filter removes dust, pollen, and other airborne irritants from outside air that is pulled into the vehicle.

The filter should be replaced as part of routine scheduled maintenance. Inspect the passenger compartment air filter every 36 000 km/

or areas with high dust levels.

Replacement may also be needed if there is a reduction in air flow, excessive window fogging, or odors.
