Rear view camera
General notes
Rear view camera C is an optical parking and
maneuvering aid. It shows the area behind the
vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text shown in the multimedia system
depends on the language setting. The follow- ing are examples of rear view camera displays
in the multimedia system.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. Make sure
that there are no persons, animals or objects in
the maneuvering area while maneuvering and
parking in parking spaces.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner: R
if the tailgate is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the camera is exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)194

Object detection only works in wide-angle view.
To ensure that you can use the function, it must
be switched on in the multimedia system (see
the Digital Operator's Manual).
360° Camera
General notes The 360° camera is a system consisting of four
cameras.
The system processes images from the follow-
ing cameras: R
Rear view camera R
Front camera R
Two side cameras in the exterior mirrors
The cameras cover the immediate surroundings
of the vehicle. The system supports you, for
example when parking or if vision is restricted at
an exit.
You can show images from the 360° camera in
full-screen mode or in seven different split-
screen views on the multimedia system. A split-
screen view also includes a top view of the vehi-
cle. This view is calculated from the data sup-
plied by the installed cameras (virtual camera).
The seven split-screen views are: R
Top view and picture from the rear view cam-
era (130° viewing angle) R
Top view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle) R
Top view and enlarged rear view R
Top view and enlarged front view R
Top view and trailer view (vehicles with trailer
tow hitch) R
Top view and images from the rear-facing side
cameras (rear wheel view) R
Top view and images from the forward-facing
side cameras (front wheel view)
When the function is active and you shift the
transmission from [ or ^ to \\ , the guide
lines on the multimedia system are hidden.
When you shift between transmission positions
[ and ^ , you see the previously selected front
or rear view. Distances measured by Parking Assist
PARKTRONIC will also be optically displayed: R
in split screen view as red or yellow brackets
around the vehicle icon in the top view, or R
at the bottom right as red or yellow brackets
around the vehicle symbol in full-screen mode
The line thickness and color of the brackets
show how far the vehicle is from an object. R
yellow brackets with thin lines: Parking Assist
PARKTRONIC is active R
yellow brackets with normal lines: an object is
present in close range of the vehicle R
red line: an object is present in the immediate
close range of the vehicle
Important safety notes The 360°camera is only an aid and may show a
distorted view of obstacles, show them incor-
rectly or not at all. The 360°camera is not a
substitute for attentive driving.
You are always responsible for safe maneuver-
ing and parking. Make sure that there are no
persons, animals or objects in the maneuvering
area while maneuvering and parking in parking
spaces.
You are always responsible for safety, and must
always pay attention to your surroundings when
parking and maneuvering. This applies to the
areas behind, in front of and beside the vehicle.
You could otherwise endanger yourself and oth-
ers.
The 360° camera will not function or will func-
tion in a limited manner: R
if the doors are open R
if the exterior mirrors are folded in R
if the tailgate is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the cameras are exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) R
if the camera lenses fog up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature R
if the camera lenses are dirty or covered R
if the vehicle components in which the cam-
eras are installed are damaged. In this case,
have the camera position and setting checked
at a qualified specialist workshopDriving systems 199

sors. A warning lamp lights up in the exterior
mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audible warning.
Blind Spot Assist supports you from a speed of
approximately 20 mph (30 km/h).
Important safety notes
G WARNING
Blind Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly. Monitoring area In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain, snow or spray R
there are narrow vehicles, e.g. motorcycles or
bicycles R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
At a distance of around 1.6 ft (0.5 m) D from the
vehicle, Blind Spot Assist monitors the area up
to 10 ft (3 m) next to

This function is available in the range between
40 mph and 120 mph (60 km/ ha nd 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
G WARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep-
ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work R
the lane markings are worn away, dark or cov-
e red up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are highly variable shade conditions on
the roadway
