TPMS sensor by increasing
or decreasing the tire's air

Vehicle Care

Tire Inspection

We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage. See When It
Is Time for New Tires on
page 10 51 for more information.

Tire Rotation

Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km). See
Scheduled Maintenance on
page 11 2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
