Owner's Manual radio* or navigation*. This improves the audibility of the parking
aid.
Rear parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the
vehicle or carrying out similar manoeuvres.

You should therefore satisfy yourself, before reversing, that there is no
The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The tones

small obstacle, such as a rock, thin post, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.
•
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the
parking aid.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
A
A ⇒ fig. 149). The interval between the warning signals becomes shorter as the
clearance is reduced.
B
A continuous tone sounds from a distance of approx. 30 cm (area A) - danger area.
Note
You should not reverse any further after this signal sounds! If the vehicle is
equipped with a factory-fitted towing device*, the border of the danger area starts,
continuous tone, 5 cm further behind the vehicle. The vehicle can be extended
through an installed detachable towing device.
•
The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device*).
•
If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your vehicle, this indi-
cates a system fault. Have the fault rectified by a specialist workshop.
On vehicles equipped with a factory-fitted radio* or navigation*, the distance to the
obstruction is shown graphically on the display. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is also
informed of the radio* or the navigation* by a graphic display (vehicle towing a
trailer) on the display. The radio* or navigation*, which is factory-fitted, can be set
so that the play function volume decreases when activating the parking aid, see

The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
