•Open the Vehicle settings menu in the Infotainment system.
•Touch the Tyres function button.
•Touch the SET function button.
•When all four tyre pressures correspond to the required values, touch the Confirm function
button.
After an extended driving time with driving at different speeds, the system will automatically learn
the new values and monitor them.
•If the tyre pressures have been changed.
•If one or more wheels have been changed.
•If the wheels have been swapped round, e.g. from front to rear ⇒ Rotating wheels front to rear.
The Tyre Pressure Loss Indicator stops working if there is a fault in the ESC or ABS ⇒ Brake
support systems.
After a warning about the tyre pressure being too low, switch the ignition off and then back
on again. The Tyre Pressure Loss Indicator can only then be re-synchronised.

the vehicle is in motion using pressure sensors on the tyres. The system warns the driver in the
event of a pressure loss.
Display of tyre pressures on the instrument cluster
Open the menu Vehicle status in the instrument cluster display ⇒ Instrument cluster. The vehicle
is displayed with the target and actual pressures of all the wheels ⇒ Fig. 234.
When the ignition is switched on, the last measured tyre pressures will be displayed first; these
values will be updated when the journey is started. If the tyre pressure is too low, the respective
actual values and the affected tyres will be marked ⇒ Fig. 234.
If the tyres are in rest state, the sensors will not transmit any tyre pressures. This stops the sensor
batteries discharging.
If no tyre pressures are transmitted, the last received values are shown in grey.
Switching the Tyre Pressure Monitoring System on and off
Observe any country-specific legal requirements for the Tyre Pressure Monitoring System.
If a set of tyres is fitted to the vehicle where the tyres either do not have wheel sensors or have
wheel sensors that are not compatible with the vehicle, the indicator lamp will flash for
approximately one minute and then light up steadily. The tyre pressures will not be monitored. The
system cannot be switched off.
Adjusting the tyre pressure
Following any relevant change in the vehicle load, the tyre pressure must be checked and altered
as necessary. The tyre pressures recommended for the vehicle are on a sticker on the driver door
pillar or on the inside of the tank flap ⇒ Tyre pressure.
