TPMS Sensor Matching
Process Auto Learn
Function
Each TPMS sensor has a
unique identification code. The
identification code needs to be
matched to a new 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) 0 129 or
Driver Information Center
(DIC) (Uplevel) 0 132. 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.
Vehicle Care

Tire Rotation

Tires should be rotated
according to the interval
specified in the
Maintenance Schedule. See
Maintenance Schedule
0 469.
Tires are rotated to
achieve a 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 0 431
and
Wheel Replacement 0 436.
