If the tyre is overinflated by more than
35 kPa (5 psi), the horn will sound multiple
times and the indicator lamp will continue
to flash for several seconds after filling
stops. To release and correct the pressure,
while the indicator lamp is still flashing,
briefly press the centre of the valve stem.
When the recommended pressure is reached,
the horn sounds once.
If the indicator lamp does not flash within
15 seconds after starting to inflate the tyre,
the tyre fill alert has not been activated or
is not working.
If the hazard warning flashers are on, the
tyre fill alert visual feedback will not work
properly.
The TPMS will not activate the tyre 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 tyre.
.
There is a malfunction in the TPMS.
.
There is a malfunction in the horn or
indicator lamps.
.
The identification code of the TPMS
sensor is not registered to the system.
.
The battery of the TPMS sensor is low.
If the tyre 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 tyre fill alert feature is not working,
use a tyre pressure gauge.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification code
needs to be matched to a new tyre/wheel
position after rotating the vehicle's tyres or
replacing one or more of the TPMS sensors.
The TPMS sensor matching process should
also be performed after replacing a spare
tyre with a road tyre containing the TPMS
sensor. The malfunction light and the DIC
message should go off at the next ignition
cycle. The sensors are matched to the tyre/
wheel positions, using a TPMS relearn tool,
in the following order: driver side front tyre,
passenger side front tyre, passenger side
rear tyre, and driver side rear tyre. See your
dealer for service or to purchase a
relearn tool.
You have two minutes to match the first
tyre/wheel position, and five minutes overall
to match all four tyre/wheel positions. If it
takes longer, the matching process stops
and must be restarted.
The TPMS sensor matching process is
outlined below:
1. Apply the parking brake.
2. Place the vehicle in Service Mode. See
3. Make sure the Tyre Pressure info display
option is turned on. The info displays on
the DIC can be turned on and off
through the Options menu. See
.
4. Use the DIC controls on the right-hand
side of the steering wheel to scroll to
the Tyre Pressure screen under the DIC
info page.
5. Press and hold the thumbwheel located
in the centre of the DIC controls on the
right-hand side of the steering wheel.
The horn sounds twice to signal the
receiver is in relearn mode and the TYRE
LEARNING ACTIVE message displays on
the DIC screen.
6. Start with the driver side front tyre.
7. Place the relearn tool against the tyre
sidewall, near the valve stem. Then press
the button to activate the TPMS sensor.
A horn chirp confirms that the sensor
identification code has been matched to
this tyre and wheel position.
