Tyre pressure monitoring (TPMS)*
25
-
rectifying low tyre pressure
The tyre pressure monitoring system TPMS
(Tyre Pressure Monitoring System)
26
warns
the driver when the pressure is too low in one
or more of the car's tyres and indicates the
tyre to which it applies.
Yellow is shown at the first indication of low
tyre pressure, stop and check the tyre pres-
sure as soon as possible.
Red indicates a much lower pressure than
recommended, stop and rectify the tyre pres-
sure immediately.
If a message for low tyre pressure is shown in
the display:
1. Check the tyre pressure on the tyre in
question.
2. Inflate the tyre(s) to the correct pressure.
3. Drive at least at 30 km/h for several
minutes and check that the message dis-
appears.

The TM (Tyre Monitor) system senses the
rotation speed of the tyres in order to deter-
mine whether they have the correct tyre pres-
sure. If the pressure is too low, the tyre's
diameter is changed and, as a result, so is the
rotation speed. By comparing the tyres with
each other the system can determine whether
one or more tyres have pressure that is too
low.
Messages
If the tyre pressure is too low then a warning
lamp (
) illuminates in the combined instru-
ment panel and one of the following mes-
sages is shown:
•
Tyre pressure low Check front right
tyre
•
Tyre pressure low Check front left

•
Tyre pressure low Check rear right

•
Tyre pressure low Check rear left tyre
•

The tyre pressure system is currently
not active
IMPORTANT
If a fault occurs in the TM system the
warning lamp
in the combined instru-
ment panel will flash for approx. 1 minute
and then illuminate with a constant glow. A
message is also shown in the combined
instrument panel.
The system does not replace normal tyre
maintenance.
TM calibration
In order for TM to work correctly, a reference
value for the tyre pressure must be deter-
mined. This must be performed each time the
tyres are changed or the tyre pressure is
changed.
