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.
The menu can be selected by the
buttons on the turn signal lever.
Press the MENU button to select the
Vehicle Information MenuX.
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
Driver Information Centre.
Vehicle care
A detected low tyre pressure
condition is indicated by the control
indicator w 3 119.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 308.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
