Seasonal temperature changes will
affect tyre pressure and the TPMS will
monitor the actual tyre pressure in the
tyre.
TPMS (Tyre Pressure Monitoring System) -
Wireless version with sensors
This system uses wireless technology
with wheel rim mounted electronic
sensors to monitor tyre pressure levels.
Sensors, mounted to each wheel as part
of the valve stem, transmit tyre pressure
readings to the receiver module.
NOTE It is particularly important for
you to check the tyre pressure in all of
the tyres on your car monthly and to
maintain the proper pressure.
The TPMS consists of the following
components:
Receiver module,
Four tyre pressure monitoring sensors,
Various tyre pressure monitoring
system messages, which are displayed on
the instrument panel display.
Tyre pressure monitoring system
warning light
Low tyre pressure indication
The warning light will light up on
the instrument panel and an acoustic
warning will sound when pressure is
low in one or more tyres. In addition,
the instrument panel will display a "Low
tyre Pressure" message and a graphic
showing the pressure values of each tyre.
The low tyre pressure values appear in a
different colour.

Should this occur, stop as soon as
possible and inflate the tyres with low
pressure (highlighted or in a different
colour in the instrument panel display
graphic) to the recommended cold
pressure value shown on the tyre
information placard. Once the system
receives the updated tyre pressures, the
system will automatically update, the
pressure values in the graphic display
in the instrument panel will stop being
highlighted or return to their original
colour and the warning light will turn
off.
NOTE When inflating warm tyres, the
tyre pressure may need to be increased
up to an additional 0.28 bar above the
cold tyre inflation pressure indicated on
the tyre information placard in order to
turn the warning light off.
The car may need to be driven for up to
10 minutes above 24 km/h in order for
the TPMS to receive this information.
TPMS check message
If a system fault is detected, the
warning light will flash for about 75
seconds and then remain continuously
lit. The system fault will also sound
a acoustic warning. In addition, the
instrument panel will display a "Service
TPM system" message for a minimum of
five seconds and then display dashes
(- -) in place of the pressure value to
indicate which sensor is not being
detected.
If the ignition key is removed from
the ignition and then re-inserted, this
sequence will be repeated, provided
that the system fault still exists. If the
system fault has been solved, the
warning light will no longer flash, the
"Check TPMS" message will no longer
be displayed and a pressure value will
be displayed in place of the dashes. A
system fault can occur due to any of the
following:
Jamming due to electronic devices
or driving next to facilities emitting the
same Radio Frequencies as the TPM
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Lots of snow or ice around the wheels
or wheel housings.
