A tire with too little or no tire inflation pres-
sure may heat up significantly and sustain
damage. This will have a negative impact
on aspects of handling, such as steering and
braking response. There is a risk of accident.
Regularly check the tire inflation pressure,
and correct it as needed, for instance twice
a month and before a long trip.

Tire pressure specifications
In the tire inflation pressure table

The current tire inflation pressure values and
the intended tire inflation pressure values for
the mounted tires can be displayed on the con-
trol display.
To ensure that they are displayed correctly, the
tire sizes must be stored in the system and
must have been set for the mounted tires.
The current tire inflation pressure value is lo-
cated on each tire.
The reference tire inflation pressure value is
located in the lower area of the control display.
Checking the tire pressure
General information
Tires heat up while driving. The tire pressure
increases with the tire temperature.
Tires have a natural, consistent tire pressure
loss.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
