Caution
Tyre pressure monitoring system
warns only 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.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information Centre
(DIC).
The menu can be selected by the
buttons on the turn signal lever.
Press MENU to select the Vehicle
Information MenuX.
Vehicle care
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
DIC.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 118.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 307.
