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 when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 6-72.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oil on
page 6-17. 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/retailer 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 6-20.
When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for Maintenance I should
be performed at every engine oil change. The services
described for Maintenance II should be performed when:
• Maintenance I was performed the last time the
engine oil was changed.
• It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since the
last service.
