replaced and the sensor
matching process is performed
successfully. See TPMS Sensor
Matching Process later in this
section.
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" later in this section.
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 0 298.
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 0 194.
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.
