Vehicle Care
Repeat these steps for all underinflated tires
that have illuminated the low tire pressure
warning light.
{
Warning
Overinflating a tire could cause the tire
to rupture and you or others could be
injured. Do not exceed the maximum
pressure listed on the tire sidewall. See
and
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound multiple
times and the turn signal 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)
. 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.
