General notes The 360° camera is a camera system that
consists of four cameras.
The system evaluates images from the fol-
lowing cameras:
R reversing camera
R front camera
R two cameras in the exterior mirrors
The cameras cover the immediate surround-
ings of the vehicle. The system assists you,
e.g. when parking or at exits with reduced
visibility.
You can show pictures from the 360° camera in full-screen mode or in seven different split-
screen views on the COMAND/Audio 20 dis- play. A split-screen view also includes a top
view of the vehicle. This view is calculated
from the data supplied by the installed cam-
eras (virtual camera).
The seven split-screen views are:
R top view and image from the reversing 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 Driving systems

R top view and images from the rear-facing
mirror cameras (rear wheel view)
R top view and images from the forward-
facing mirror cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the guidelines
in the COMAND display 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 and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360° camera is
not a substitute for attentive driving.
You are responsible for safe manoeuvring and
parking. Make sure that there are no persons,
animals or objects in range while manoeu-
vring and parking.
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and manoeuvring. 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 only in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in
R if the boot lid 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 mist up, e.g. when
driving into a heated garage in winter, caus- ing a rapid change in temperature R
if the camera lenses are dirty or covered
R if the vehicle components in which the
cameras are fitted are damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop.
Do not use the 360° camera in this case. You could otherwise injure others or damage
objects when parking the vehicle.
Guide lines are always shown at road level.
In trailer mode, the guide lines are shown at
the level of the trailer coupling.
The camera in the rear area is protected by
means of a flap. This flap opens when the
360° camera is activated. Observe the notes
on cleaning (Y page 401). For technical rea-
sons, the flap may remain open briefly after
the 360° camera has been deactivated.
Activation conditions The 360° camera image can be displayed if:
R COMAND Online/Audio 20 is switched on,

Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 309).
The system determines the attention level
of the driver depending on the setting
selected:
Selection Standard Standard: the sensitivity with
which the system determines the attention
level is set to normal.
Selection Sensitive Sensitive: the sensitivity is set
higher. The attention level detected by Atten- tion Assist is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the é symbol appears in the multifunction
display in the assistance graphic display.
When ATTENTION ASSIST has been deactiva-
ted, it is automatically reactivated after the
engine has been stopped. The sensitivity
selected corresponds to the last selection
activated (standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: ATTENTION ASSIST ATTENTION ASSIST

Take a break! .
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND. Traffic Sign Assist
General notes Traffic Sign Assist displays the maximum
speed permitted and overtaking restrictions
to the driver in the instrument cluster. Driving onto a section of road in the wrong direction
triggers a warning. Traffic Sign Assist detects traffic signs with camera system :attached
behind the top of the windscreen. The data
and general traffic regulations stored in the
navigation system are also used to determine
the current speed limit.
If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits and
overtaking restrictions is updated. 256
Driving systemsDriving and parking
No entry (wrong-way warning)
If no entry signs or roundabout signs are
passed, warning message :is displayed in
the instrument cluster if Traffic Sign Assist
detects that you are driving in the wrong
direction. You will then also hear a warning
tone. You should immediately check your
direction of travel in order to avoid danger to yourself and other road users. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 259) and Lane Keeping
Assist (Y page 261).
Blind Spot Assist General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors draws your attention to vehicles detected in
the monitored area. If you then switch on the corresponding turn signal to change lanes,
you will also receive a visual and audible col-
lision warning.
Blind Spot Assist supports you from a speed
of approximately 30 km/h. Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
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
integrated 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 spe-
cialist workshop. Blind Spot Assist may no
longer work properly.
Monitoring range
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicy-
cles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their
lane
R barriers or other road boundaries Driving systems
259Driving and parking Z
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly next to
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if there are vehicles at the edge of
their lane nearest your vehicle.
Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for a prolonged time
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam- age to the bumpers, have the function of the
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly. Warning display
:
Warning display
Blind Spot Assist is not active at speeds below approximately 30 km/h. Vehicles in the mon-
itoring range are then not indicated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning
always lights up when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 12 km/h.
If you select the reverse gear, Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If
the turn signal remains on, detected vehicles
are indicated by the flashing of red warning
lamp :. There are no further warning tones. 260

Lane Keeping Assist monitors the area in
front of your vehicle by means of camera
:
at the top of the windscreen. Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally.
This function is available in the range between
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 by means of intermittent vibration through the
steering wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
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 in 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. Driving systems
261Driving and parking
Z
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
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 road, weather or traffic conditions. Lane
Keeping Assist is only an aid. You are respon-
sible for the distance to the vehicle in front,
for vehicle speed, for braking in good time,
and for staying in lane.
Lane Keeping Assist does not keep your vehi- cle in its lane.
