Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 metres and in front up to
1.2 metres . Depending on which side
of the vehicle is closer to an obstacle,
you will hear acoustic warning signals
in the vehicle on the respective side.
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 rear and
front obstacles is displayed by
changing distance lines in the Driver
Information Centre 3 96 or,
depending on the version, on the Colour-Info-Display 3 101.

and an acoustic signal is given.
If the driver does not stop the vehicle
within ten metres for parallel parking
slots or six metres for perpendicular parking slots after a parking slot is
proposed, the system starts to search
for another suitable parking slot.Park guiding mode
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within ten
metres for parallel parking slots or six metres for perpendicular parking slots
after the Stop message is given. The
system calculates the optimal path
into the parking slot.
A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle is steered
into the slot automatically by giving
the driver detailed instructions for braking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.Always pay attention to the sound of
the front-rear parking assist.
Continuous sound indicates that the
distance to an obstacle is less than
approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
