Parking assist
General information
When attaching a trailer or bike
carrier to the trailer hitch, the parking
assist is deactivated.9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
Rear parking assist
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system operates with ultrasonic
parking sensors in the rear bumper.
Activation
Rear parking assist is activated when reverse gear is engaged and ignition
is switched on.
The system is ready to operate when
the LED in the parking assist button
r OFF does not illuminate.
Indication
The system warns the driver with acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm while reverse gear is engaged.
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.
162Driving and operatingAdditionally, the distance to rear
obstacles is displayed by changing
