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

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

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
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning
Rnot 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.
GWARNING
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:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions on the roadway

Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking recognized as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must have been
detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. Oncoming vehicles, over-
taking vehicles and vehicles in adjacent lanes
can be detected.
A further lane-correcting brake application can
only occur after your vehicle has returned to the
original lane.
No lane-correcting brake application occurs if:
Ryou clearly and actively steer, brake or accel-
erate.
Ryou cut the corner on a sharp bend
Ryou have switched on the turn signal
Ra driving safety system intervenes, e.g. ESP®,
PRE-SAFE®Brake or Active Blind Spot Assist
Ryou have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
RESP®is switched off
Rthe transmission is not in position h.
Ron vehicles with a trailer tow hitch, the elec-
trical connection to the trailer has been cor-
rect
ly established
Ra loss of tire pressure or a defective tire has
been detected and displayed.
Ran obstacle has been detected in the lane in
which you are driving
Active Lane Keeping Assist may not detect other
road users or traffic situations. An inappropriate
brake application may be interrupted at any time
if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Ryou brake or accelerate significantly.
A lane-correcting brake application is interrup-
ted automatically if:
Ra driving safety system intervenes, e.g. ESP®,
PRE-SAFE®Brake or Active Blind Spot Assist
Rlane markings are no longer detected

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.
