Activation
When reverse gear is engaged, the

The front parking assist is also
activated automatically at a speed up
to 11 km/h.
An illuminated LED in the parking
assist button r or D indicates that
the system is ready to operate.
If the vehicle exceeds a speed of
11 km/h, the front parking assist is
deactivated. The front parking assist
is always reactivated when vehicle
speed drops below 11 km/h.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind and in
front of the vehicle. Depending on
which side of the vehicle is closer to
an obstacle, you will hear acoustic
warning signals on the respective
side of the vehicle. The interval
between the sounds becomes shorter
as the vehicle gets closer to that
obstacle. When the distance is less
than approx. 30 cm, the sound is
continuous.
Additionally, the distance to obstacles
may be shown in the DIC 3 120.
Driving and operating
The distance to a front and rear
obstacle is indicated by changing
distance lines around the vehicle.
Rear obstacles are indicated
acoustically and visually at the same
time.
Front obstacles are indicated visually
first. At distances less than 80 cm an
acoustic signal also sounds.
The distance indication in the DIC can
be inhibited by vehicle messages with
a higher priority. After approving the
message by pressing the SET/CLR
button on the turn signal lever,
distance indication appears again.
