154Driving and operatingThe parking assist makes reverse
parking easier by measuring the
distance between the rear of the
vehicle and obstacles.
The system consists of four ultrasonic parking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
An obstacle is indicated by buzzers
and, depending on vehicle, is also
indicated in the Info-Display. The
interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the
buzzer is continuous.
Notice
In versions with Info-Display
indication, the volume of the buzzer can be adjusted via the Infotainment system. Refer to Infotainment
manual for further information.
DeactivationIt is possible to permanently or
temporarily deactivate the system.
Notice
In versions with Info-Display
indication, the function can be
deactivated via the Infotainment
system. Refer to Infotainment
manual for further information.
Temporary deactivation
Temporarily deactivate the system by
pressing r on the instrument panel
with the ignition on. LED illuminates in
the button when deactivated.
When reverse gear is selected, no
acoustic signal will sound, indicating
deactivation.
The function is reactivated by
pressing r again or the next time
the ignition is switched on.
Permanent deactivation
Permanently deactivate the system
by pressing and holding r on the
instrument panel for approx.
three seconds with the ignition on.
LED illuminates continuously in the
button when permanently
deactivated.
Driving and operating155The system is deactivated and will not
operate. When reverse gear is
selected, no acoustic signal will
sound, indicating deactivation.
The function is reactivated by
pressing and holding r for approx.
three seconds.
Fault
If the system detects an operating
fault, when selecting reverse gear a continuous acoustic alarm will sound
for approx. five seconds, a
corresponding message appears in
the Driver Information Centre 3 100
and F illuminates in the instrument
cluster 3 96. Consult a workshop to
have the cause of the fault remedied.Caution
When reversing, the area should
be free from obstacles which could impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.

Basic notes on parking assist
system
9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the sensors can
be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
The parking assist system will not
detect objects which are out of the detection range of the sensors.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
either the interior mirror or the
Infotainment system display screen.
