The tire sizes of the mounted tires can be gath‐
ered from the tire inflation pressure details on the
vehicle, refer to page 286, or directly on the tires.
The tire details do not need to be re-entered
when the tire inflation pressure is corrected.
For summer and winter tires, the tire details en‐
tered last are stored. After a tire or wheel re‐
placement, the settings of the tire sets used last
can be selected.

Current tire temperature
Depending on the model, the current tire tem‐
peratures are displayed.
The current tire temperatures may change while
driving or due to the external temperature.
The target pressure for the tires on the front and
rear axles is displayed.
The specified target pressures take the influence
of driving operation and external temperature on
the tire temperature into account. The appropri‐
ate target pressure is always displayed, inde‐
pendent of the weather situation, tire tempera‐
tures and driving times.
The displayed target pressure may change and
may differ from the tire inflation pressure details
on the door pillar of the driver's door. The tire in‐
flation pressure can thus be corrected to the
value of the displayed target pressures.
The target pressure is immediately adjusted if
the vehicle load is changed in the tire settings.
