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 0 232.

When the vehicle is used in a way that requires extended idle time, one hour of use shall be deemed the same as 33 miles. See Driver Information Center (DIC) (Base Level) 0 114 or

Driver Information Center (DIC) (Uplevel) 0 116 for hourmeter.

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

(22,500 mi) or two years, whichever comes first. Replace if necessary. More frequent replacement may be needed if the vehicle is driven in areas with heavy traffic, areas with poor air quality, or areas with high dust levels. Replacement may also be needed if there is a reduction in air flow, excessive window fogging, or odors.

The air conditioning system requires maintenance every seven years.

This service requires replacement of the desiccant to help the longevity and efficient operation of the air conditioning system. This service can be complex. See your dealer.

Rotate the tires, if recommended for the vehicle, and perform the following services. See Tire Rotation 0 275.
