Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed. Tires should be rotated every
12 000 km/7,500 miles. SeeTire Inspection and
Rotation on page 6‑70.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
When the CHANGE ENGINE OIL SOON message
displays, service is required for the vehicle as soon as
possible, within the next 1 000 km/600 miles. If driving
under the best conditions, the engine oil life system
might not indicate the need for vehicle service for more
than a year. The engine oil and filter must be changed
at least once a year and the oil life system must be
reset. Your dealer has trained service technicians who
will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 6‑22.
