lamp will continue to flash for several
seconds after filling stops. To release
and correct the pressure, while the
turn signal lamp is still flashing,
briefly press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does not flash
within 15 seconds after starting to
inflate the tire, the tire fill alert has
not been activated or is not working.
If the hazard warning flashers are on,
the tire fill alert visual feedback will
not work properly.
The TPMS will not activate the tire fill
alert properly under the following
conditions:
There is interference from an
external device or transmitter.
The air pressure from the inflation
device is not sufficient to inflate
the tire.
There is a malfunction in the TPMS.
There is a malfunction in the horn
or turn signal lamps.
The identification code of the TPMS
sensor is not registered to the
system.
The battery of the TPMS sensor
is low.
If the tire fill alert does not operate
due to TPMS interference, move the
vehicle about 1 m (3 ft) back or
forward and try again. If the tire fill
alert feature is not working, use a tire
pressure gauge.
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) 0 108 or
VEHICLE CARE
Driver Information Center (DIC)
(Uplevel) 0 111. 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.
