Driving and operating257Caution
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.
Side blind spot alert
The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
blind spot zone. The system displays
a visual alert in each exterior mirror,
when detecting objects that may not
be visible in the interior and exterior
mirrors.
Side blind spot alert uses some of the
parking assist sensors which are
located in the front and rear bumper
on both sides of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
Activation
The system is activated when the
speed of the vehicle is between
approx. 30 km/h and 140 km/h.
Page 260 of 353

258Driving and operatingDeactivation
To deactivate the system, press .
with the ignition on. The LED in the
button illuminates when deactivated.
To reactivate the system, press .
again. The LED in the button
extinguishes.
Functionality
When the system detects a vehicle in the side blind zone while driving
forwards, an LED will illuminate in the
relevant exterior mirror.
The LED comes on immediately when being passed.
The LED comes on after a delay when
passing another vehicle slowly.
The LED flashes when the turn lights
are activated and a vehicle is
detected.
Operation conditions
The following conditions must be
fulfilled for proper operation:
● all vehicles are moving in the same direction and in adjacent
lanes
● the speed of your vehicle is between 30 km/h and 140 km/h
● the traffic flow is normal
● driving on a straight or slightly curved road
● the vehicle is not pulling a trailer
● the sensors are not covered by mud, ice or snow
● the warning zones in the exterior mirrors or the detection zones in
front and rear bumper are not
covered
No alert will be given in the following
situations:
● in the presence of non-moving objects, e.g. parked vehicles,
barriers, street lamps, road signs
● with vehicles moving in the opposite direction
Page 261 of 353

Driving and operating259● driving on a winding road or asharp corner
● when passing or being passed by
a very long vehicle, e.g. lorry,
coach, which is at the same time
detected at the rear in the blind spot angle and present in the
driver's forward field of vision
● in very heavy traffic, vehicles detected in front and behind are
confused with a lorry or a
stationary object
● when passing too quickly
Fault
In the event of a fault, a
corresponding message will be
displayed in the instrument cluster.
Have the cause of the fault remedied
by a workshop.
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 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
reversing.
The camera is typically installed on
the rear doors, beneath the number
plate moulding.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Rear view display 3 40.
Note
To achieve the optimum visibility, the rear view camera must not be
obscured by dirt, snow or ice.
Activation
Interior mirror display
The interior mirror display is
automatically activated when reverse
gear is engaged. An audible signal
confirms activation.
Page 262 of 353

260Driving and operatingInfo Display
In vehicles without interior mirror
display, the rear view camera screen
is shown on the Info Display.
Trajectory lane display image (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 image (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cmSettings
Settings, e.g. brightness, can be set
via the Infotainment system. Refer to
Infotainment manual for further
information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged.
Fault
The rear view camera may not
operate 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
