Reversing camera
General notes
Rear view camera :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.
iThe 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:
Rif the tailgate is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)

To ensure that you can use the function, it mustbe 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:
RRear view camera
RFront camera
RTwo 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:
RTop view and picture from the rear view cam-
era (130° viewing angle)
RTop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
RTop view and enlarged rear view
RTop view and enlarged front view
RTop view and trailer view (vehicles with trailer
tow hitch)
RTop view and images from the rear-facing side cameras (rear wheel view)
RTop view and images from the forward-facing
side cameras (front wheel view)
When the function is active and you shift the
transmission from hork toi, the guide
lines on the multimedia system are hidden.
When you shift between transmission positions
h and k, you see the previously selected front
or rear view. Distances measured by Parking Assist
PARKTRONIC will also be optically displayed:
Rin split screen view as red or yellow brackets
around the vehicle icon in the top view, or
Rat 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.
Ryellow brackets with thin lines: Parking Assist
PARKTRONIC is active
Ryellow brackets with normal lines: an object is present in close range of the vehicle
Rred 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:
Rif the doors are open
Rif the exterior mirrors are folded in
Rif the tailgate is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the cameras are exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif the camera lenses fog up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature
Rif the camera lenses are dirty or covered
Rif 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 workshop

188Driving systems
Driving and parking
XSwitch off the engine.
XClose the doors and tailgate.
XCouple up the trailer.
XEstablish the electrical connection between
the vehicle and the trailer.
XCheck that the trailer lighting system is work-
ing.
XPush the combination switch upwards/down-wards and check whether the corresponding
turn signal on the trailer flashes.
A trailer that is connected is recognized only
when the electrical connection is established
correctly and when the lighting system is work-
ing properly. The function of other systems also
depends on this, for example:
RESP®
RPARKTRONIC
RActive Parking Assist
RActive Blind Spot Assist
RActive Lane Keeping Assist
Vehicles with AIR BODY CONTROL: if you couple
up a trailer, the vehicle always remains at high-
way level. Observe the following note when cou-
pling up a trailer:
RUnless highway level has been set manually,
the vehicle is automatically lowered to high-
way level. If a speed of 5 mph (8 km/h) has
been reached, this may be the case.
These restrictions apply to accessories that are
supplied with power via the trailer socket in your
vehicle, e.g. a rear bicycle rack.
Observe the maximum permissible trailer
dimensions (width and length).
Most U.S. states and all Canadian provinces
require by law:
RSafety chains between the towing vehicle and
the trailer. The chains should be cross-wound
under the trailer drawbar. They must be fas-
tened to the vehicle's trailer coupling, not to
the bumper or the axle.
Leave enough play in the chains to make tight
cornering possible.
RA separate brake system for certain types of
trailer.
RSafety switch for braked trailers. Check the
specific legal requirements applicable to your state.
If the trailer becomes detached from the tow-
ing vehicle, the safety feature applies the
trailer brakes.
Towing a trailer
There are several legal requirements for towing
a trailer, e.g. the maximum permissible speed.
Make sure that your car/trailer combination
complies with the local regulations:
Rin your place of residence
Rat your destination
The police and local authorities can provide reli- able information.
To accumulate driving experience and accustom
yourself to the new handling characteristics,
practice the following at a location where there
is no traffic:
RCornering
RStopping
RBacking up
Check the following before the journey:
RTrailer tow hitch
RSafety switch for braked trailers
RSafety chains
RElectrical connections
RLighting system
RWheels and tires
RLoad securing
Adjust the exterior mirrors so that you have a
clear view of the rear section of the trailer.
If the trailer is equipped with electronically con-
trolled brakes, pull away carefully in the car/
trailer combination. Brake manually using the
brake controller and check whether the brakes
function correctly.
Regularly check that the load is secure.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning circle
Avoid sudden steering movements.
Avoid braking abruptly. If possible, brake gently
at first to allow the trailer to run on. Then,
increase the braking force rapidly.
