176Driving and operatingbehind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system operates with ultrasonic
parking sensors in the rear and front
bumper.
Activation
In addition to the rear parking assist,
the front parking assist is triggered
when an obstacle is detected in front
and the speed of the vehicle is still
below 6 mph.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
When the system is deactivated, the
LED in the button illuminates.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle and behind the vehicle.
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 Info-
Display 3 101.
If the vehicle stops for more than
three seconds in a forward gear, if
automatic transmission is in P or if no
further obstacles are detected, no
acoustic warning signals are given.
