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 mi) and 16 000 km
(10,000 mi) since the last oil change. Under severe conditions,
the CHANGE OIL message may be displayed before 5 000 km
(3,000 mi).
The vehicle MUST NOT be driven more than 16 000 km (10,000 mi)
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 mi) or sooner if the CHANGE OIL message is displayed.
Footnotes
[Dagger] The U.S. Environmental Protection Agency or the California
Air Resources Board has determined that the failure to perform this maintenance
item will not nullify the emission warranty or limit recall liability
prior to the completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.
A good time to check your brakes is during the tire rotation.
