360° camera (surround view)
General notes
The 360° camera is a system consisting of
four cameras.
The system analyzes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo cameras in the exterior rear view mir-
rors
The cameras capture the immediate sur-
roundings of the vehicle. The system sup-
ports you, e.g. when parking or if vision is
restricted at an exit.
The 360° camera images can be shown in full
screen mode or in seven different split-screen
views on the COMAND display. A split-screen
view also includes a top view of the vehicle.
This view is calculated from the data supplied
by the installed cameras (virtual camera).
The seven split-screen views are:
Rtop view and picture from the rear view
camera (130° viewing angle)
Rtop view and picture from the front camera
(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 rear-view images from the
exterior mirror cameras (rear wheel view)
Rtop view and forward-view images from the
exterior mirror cameras (front wheel view)
iThe top view and trailer view are available
for vehicles equipped with a trailer tow
hitch.
When the function is active and you shift the
transmission from position Dor Rto N, you
see t
he previous view in the COMAND dis-
play. The dynamic guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes
The 360° camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi- ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there
are no persons, animals or objects in the area
in which you are maneuvering.
The 360° camera may show a distorted view
of obstacles, show them incorrectly or not at
all. It cannot show objects in the following
areas:
Runder the front bumper
Rvery close to the front bumper
Rvery close to the rear bumper
Runder the rear bumper
Rin close range above the handle on the
trunk lid
Rvery close to the exterior mirrors
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and maneuvering. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.
The 360° camera will not function or will
function in a limited manner:
Rif the doors are open
Rif the exterior mirrors are folded in

your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A warning may be given if a front wheel
passes over a lane marking. It will warn you bymeans of intermittent vibration in the steer-
ing wheel for up to 1.5 second s.
Im portant safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
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.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane. The system may be impaired or may not func-
tion if:
Rthere is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in the
vicinity of the camera
Rthere are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too
small a
nd the lane markings thus cannot be
detected
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road

In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if:
Rthere is poor visibility, e.g. due to insuffi-

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
Rno vehicle is detected in the adjacent lane
and there are broken lane markings
Warning vibration in the steering wheel
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 steer-
ing wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a high-
way.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Lane-correcting brake application
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.
GWARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.
252Driving systems
Driving and parking
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
If a lane-correcting brake application occurs,
display:appears in the multifunction dis-
play.
A lane-correcting brake application can only
be made after driving over a solid, recogniz-
able lane marking. Before this, a warning
must be given by means of intermittent vibra-
tion in the steering wheel. In addition, a lane
with lane markings on both sides must be
recognized. The brake application also
slightly reduces vehicle speed.
iA further lane-correcting brake applica-
tion 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
accelerate.
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
acceleration.

cles with the ON&OFFROAD package).
Rthe LOW RANGE off-road gear is activated
(vehicles with the ON&OFFROAD package).
Rwhen a loss of tire pressure or a defective
tire has been detected and displayed.
There is a possibility that the Active Lane
Keeping Assist could misjudge the given traf-
fic situation. An inappropriate brake applica-
tion may be interrupted at any time if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
Rlane markings can no longer be recognized.
