124Driving and operating
Deviations from the maximum speed
limit may occur briefly when driving
downhill, for physical reasons.
Vehicles also equipped with cruise
control speed limiter: the maximum
speed cannot be exceeded by
depressing the accelerator pedal firmly beyond the point of resistance.
Cruise control speed limiter 3 120.
Parking assist
The parking assist makes reverse
parking easier by measuring the
distance between the rear of the
vehicle and obstacles. It is the driver,
however, who bears full responsibility for parking.
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 Infotainmentsystem. Refer to Infotainment
system manual for further
information.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.

Fault If the system detects an operating
fault, when selecting reverse gear a
continuous acoustic alarm will sound
for approx. 5 seconds, a
corresponding message appears in
the Driver Information Centre 3 86
and F illuminates in the instrument
cluster 3 82. 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.
Vehicle messages 3 87.
Rear view camera The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
the interior mirror or in the Info-
Display.
9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse the vehicle by only looking at the display and checkthe surrounding area behind and
around the vehicle before

126Driving and operating
ActivationRear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted above the
rear doors/tailgate.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Trajectory lane display (1)
Depending on version, the trajectory
lane (1) of the vehicle is shown in blue
on the Info-Display. It shows the path of the vehicle in accordance with the
steering angle.
Fixed lane display (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guiding lines (A, B, C) are used together with the fixed lane
display (2) and indicate the distance
behind the vehicle.
The guiding line intervals are as
follows:A (red)=30 cmB (yellow)=70 cmC (green)=150 cm
Settings
Settings, e.g. brightness, can be set
via the Infotainment system. Refer to
Infotainment system manual for
further information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged.
Fault The rear view camera may notoperate properly when:
■ the surrounding is dark,
■ the sun or the beam of headlights is
shining directly into the camera
lens,
■ ice, snow, mud, or anything else covers the camera lens. Clean the
lens, rinse it with water, and wipe it
with a soft cloth,
