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.
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.

Object detection The 360° camera helps detect moving and
stationary objects. If an object (person, vehi- cle, other obstacle) is detected, this object ismarked with a bar. Objects located some dis-
tance from the vehicle away are marked with a yellow bar. If the distance to the object is
very small, the bar is displayed in red.
Object detection only functions in both full-
screen modes.
In order to use the function, it must be
switched on in COMAND Online/Audio 20;
see the separate operating instructions.
Stopping the 360° camera display The 360° camera display is stopped:

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. 258
Driving systemsDriving and parking
Page 262 of 489

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 309)
of the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board
computer (Y page 308).
The following information is displayed:
R the length of the journey since the last
break
R the attention level determined by ATTEN-
TION ASSIST ( Attention level Attention level), dis-
played in a bar display in five levels from
high to low
R If ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System suspended System suspended 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 311).
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
ATTENTION 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 switched off. The sensitivity selected corresponds to the last selection
activated (standard/sensitive). Driving systems

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 that allow for adequate recuperation. If
you do not take a break and ATTEN-
TION ASSIST still detects increasing lapses in
concentration, 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.
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 currently applicable traffic regulation
continues to be shown in the assistance
graphic display (Y page 308).
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. 260
Driving systemsDriving and parking
Page 264 of 489

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 310).
If you have activated the Traffic Sign Assist
display in the on-board computer, the traffic regulations (speed limits and overtaking
restrictions) are displayed in the instrument
cluster for five seconds respectively. The
wrong-way warning and the traffic sign dis-
play for speed limits and overtaking restric-
tions remain active even when the display has
been deactivated.
