244Vehicle careCaution
Tyre pressure monitoring system
warns just about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Select the Tyre pressure monitoring
page under the Info Menu in the
Driver Information Centre 3 110
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 107.
If
w lights up, stop as soon as
possible and inflate the tyres as
recommended 3 286.
After inflating driving may be required
to update the tyre pressure values in
the Driver Information Centre. During
this time w may light up.
If w lights up at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
Vehicle messages 3 119.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
illuminates. For the further three
wheels the system remains
operational.
