Starting-off and Driving 117
On vehicles equipped with a factory-fitted radio or radio navigation system, the
distance to the obstruction is shown graphically in the display. On vehicles with a
factory-fitted towing device, the sensors are deactivated when towing a trailer.
The driver is informed about this by a graphic display (vehicle towing a trailer) in
the radio or the radio navigation display. The factory-fitted car stereo or radio nav-
igation system can be set so that the play function volume decreases when acti-
vating the parking aid, see Owner's Manual radio or radio navigation system. This
improves the audibility of the parking aid.
Front and rear parking aid
The parking aid provides a warning of obstacles in front and 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 audible signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.

WARNING
The audible parking aid determines the distance between the front or rear bump-
er and an obstacle with the aid of ultrasound sensors. The sensors are integrated
in the front and rear bumper. The signal tones for the front parking aid sound
higher as standard than for the rear parking aid. The tones of the parking aid can
be adapted in the menu of the Information display ⇒ꢀpage 19.
●
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 vehi-
cle or carrying out similar manoeuvres.
●
You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehi-
cle. Such an obstacle might not be within the range detected by the sensors.

area. From this moment on do not continue driving! If the vehicle is equipped
with a factory-fitted towing device, the indication threshold of the danger area
starts - continuous tone - 5 cm further behind the vehicle. The vehicle can be ex-
tended 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 car, this indi-
cates a system fault. Have the fault rectified by a specialist workshop.
On vehicles equipped with a factory-fitted radio or radio navigation system, the
distance to the obstruction is shown graphically in the display. On vehicles with a
factory-fitted towing device, the rear sensors are deactivated when towing a trail-
er. The driver is informed about this by a graphic display (vehicle towing a trailer)
in the radio or the radio navigation display. The factory-fitted car stereo or radio
navigation system can be set so that the play function volume decreases when
activating the parking aid, see Owner's Manual radio or radio navigation system.
This improves the audibility of the parking aid.
●
The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
