tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes before
the system recalculates. The following
relearn process takes up to
10 minutes, driving at a minimum
speed of 20 km/h (12 mph). A dash (-)
or pressure value will display in the
DIC. See Driver Information Center
(DIC) (Base Level) 0 112 or
Driver Information Center (DIC)
(Uplevel) 0 115. A warning message
displays in the DIC if a problem
occurs during the relearn process.

Tire Inspection

We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected for
signs of wear or damage at least
once a month.
Replace the tire if:
The indicators at three or more
places around the tire can
be seen.
There is cord or fabric showing
through the tire's rubber.
The tread or sidewall is cracked,
cut, or snagged deep enough to
show cord or fabric.
The tire has a bump, bulge,
or split.
The tire has a puncture, cut,
or other damage that cannot be
repaired well because of the size
or location of the damage.

Tire Rotation

Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule 0 381.
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is noticed,
rotate the tires as soon as
possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See When It Is Time for
New Tires 0 355 and
Wheel Replacement 0 359.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and Loading
Information label after the tires
have been rotated. See Tire
Pressure 0 348 and
Vehicle Load Limits 0 218.
