At your dealer, you can be certain that you will receive
the highest level of service available. Your dealer has
specially trained service technicians, uses genuine
replacement parts, as well as, up‐to‐date tools and
equipment to ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7‑9andMaintenance Replacement Partson
page 7‑11. We recommend the use of genuine parts
from your dealer.
Rotation of New Tires
Tire rotation is not recommended if the vehicle has
different size tires on the front and rear wheels. If tire
rotation is recommended for the vehicle, 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. See Tire Inspection and
Rotation on page 6‑65.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑16. 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 6‑20.
When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.

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.
