display in yellow or red respectively.
Object detection The reversing camera can detect moving and
stationary objects. If, for example, a pedes-
trian or another vehicle is detected, these
objects are marked with bars. The system is
only able to detect and mark stationary
objects when your vehicle is moving. When
the vehicle is stationary, moving objects can
be detected and marked.
To ensure that you can use the function, it
must be switched on in COMAND (see the
separate operating instructions). 360° camera (surround view)
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 360° camera assists
you, for instance when parking or at exits with reduced visibility.
You can show pictures from the 360° camera
in full-screen mode or in six 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 six 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
R top view and enlarged front view
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.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that
there are no persons, animals or objects in
range while manoeuvring and parking. Driving systems
221Driving and parking Z

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.
Observe the notes on cleaning
(Y page 347)
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.
The guide lines in the COMAND display show the distances to your vehicle. The distances
only apply to road level.
i The camera in the rear area is protected
from raindrops and dust by means of a flap. This flap opens when the 360° camera is
activated.
The flap closes again when:
R you have finished the manoeuvring proc-
ess
R you switch off the engine

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h range. If ATTENTION ASSIST
detects typical indicators of fatigue or
increasing lapses in concentration on the part
of the driver, it suggests taking a break. Driving systems
225Driving and parking Z

Important safety notes
ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentra-
tion until too late, or may not detect them at
all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with the active Steer
Assist of DISTRONIC PLUS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con- tinue your journey if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
Displaying the attention level You can have current status information dis-
played in the assistance menu (Y
page 257)
of the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board
computer (Y page 256).
The following information is displayed:
R the length of the journey since the last
break
R the attention level determined by ATTEN-
TION ASSIST, displayed in a bar display in
five levels from high to low
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System passive System passive message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 60 km/h or above 200 km/h.
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 259).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: 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). 226

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!
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
continues to detect increasing lapses in con- centration, 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 Online. You can select a service
station and navigation to this service station
will then begin. This function can be activated
and deactivated in COMAND Online. 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.
The display can also be updated without a
visible traffic sign if:
R the vehicle changes roads (e.g. motorway
exit or slip road)
R a village or town boundary is passed which
is stored in the digital map
R the last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction
(speed limit or overtaking restriction) is
passed, the sign is displayed for five seconds. The applicable traffic regulation then appears
in the instrument cluster.
The camera also detects traffic signs with a
restriction indicated by an additional sign
(e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either. Driving systems
227Driving and parking Z

Traffic Sign Assist is not available in all coun-
tries. In this case, display :is shown in the
speedometer.
Important safety notes Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits
and overtaking restrictions. Traffic signs
always have priority over the Traffic Sign
Assist display.
The system may be either functionally
impaired or temporarily unavailable if:
R visibility is poor, e.g. due to snow, rain, fog
or spray
R there is glare, e.g. from the sun being low in
the sky
R there is dirt, ice or misting on the wind-
screen in the vicinity of the camera
R traffic signs are hard to detect (dirt, ice,
snow)
R the traffic signs are insufficiently lit at night
R signs are ambiguous (e.g. traffic signs on
construction sites or in adjacent lanes)
R the information in the digital street map of
the navigation system is incorrect or out of
date
Activating Traffic Sign Assist X
Activate the Traffic Sign Assist display
using the on-board computer
(Y page 258).
If you have activated the display of Traffic
Sign Assist in the on-board computer, the traffic regulations (speed limits and overtak-
ing restrictions) are displayed in the instru-
ment cluster. The wrong-way warning
remains active even when the display has
been deactivated.
Instrument cluster display Speed limit with overtaking restriction

Speed limits in wet conditions
:
Maximum permitted speed
; Additional signs for wet conditions
A maximum permitted speed of 80 km/h
(80 mph) applies in wet conditions and when
Traffic Sign Assist has determined that the
restriction must be observed.
Cancelling the overtaking restriction A maximum permitted speed of 60 km/h
(60 mph) :applies. The overtaking restric-
tion no longer applies ;. The crossed-out no
overtaking traffic sign is displayed for five
seconds. End of a speed limit No speed limit
:applies here.
i The unit for the speed limit (km/h or mph)
depends on the country in which you are
driving. It is generally neither shown on the
traffic sign nor on the instrument cluster
but must be taken into account when
observing the maximum permitted speed.
No entry (wrong-way warning) :
Warning message in the instrument clus-
ter (wrong-way warning)
If no entry signs or roundabout signs are
passed, a 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. Driving systems

X Use a soft cloth and water to clean the infrared camera. Driving Assistance Plus package
General notes The Active Driving Assistance PLUS package
consists of DISTRONIC PLUS (Y page 191),
Active Blind Spot Assist (Y page 233) and
Active Lane Keeping Assist (Y page 236).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas
on either side of the vehicle that are not visi-
ble to the driver with two lateral, rear-facing
radar sensors. A warning display in the exte-
rior 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 collision warning. If a risk of side impact is detected, corrective braking may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direc-
tion of travel and to the side before making a
course-correcting brake application. For this, Active Blind Spot Assist uses the forward-
facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving. Driving systems
233Driving and parking Z

G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. 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.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers
and behind a cover in the radiator trim. Make sure that the bumpers and the cover in the
radiator trim are free of dirt, ice or slush. The rear sensors must not be covered, e.g. by
bicycle 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. Active Blind Spot Assist may oth-
erwise no longer function properly.
Monitoring range G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. Active Blind Spot Assist monitors the area up
to 3.0 mbehind your vehicle and directly next
to your vehicle, as shown in the diagram.
The detection of vehicles may be impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicy-
cles, or may only detect them too late.
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 particularly long vehicles, for
example lorries, for a prolonged time 234
