After releasing the brake, start driving immedi-
ately; otherwise, the acceleration assistant will
no longer hold the vehicle after approx. 2 sec-
onds and the vehicle will start to roll back-
ward.<

2.
Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure in one tire drops signifi-
cantly in relation to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
3.
Begin driving.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
The initialization is completed while driving,
without requiring any further input from you.

tion, an acoustic signal sounds. There is
a flat tire or extensive inflation pressure
loss.

Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
In the following situations, the system could be
