DIC message should go off after
the road tyre is replaced and the
sensor matching process is
performed successfully. See TPMS
Sensor Matching Process
following.
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tyres. The
malfunction light and the DIC
message should go off after
successfully completing the sensor
matching process. See "TPMS
Sensor Matching Process"
following.
One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See your
dealer for service.
Replacement tyres or wheels do
not match the original equipment
tyres or wheels. Tyres and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tyres 0 283.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tyre condition. See your dealer for
service if the TPMS malfunction light
and DIC message come on and
stay on.
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 power mode in
ON/RUN/START. See Ignition
Positions 0 195.
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
Settings menu. See Driver
Information Centre (DIC) 0 135.
4. Use the five-way DIC control on
the right side of the steering
wheel to scroll to the Tyre
