in the multimedia system.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in which
you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner: R
if the trunk lid is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the camera is exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) R
if there is a sudden change in temperature,
e.g. when driving into a heated garage in win-
ter R
if the camera lens is dirty or obstructed
Observe the notes on cleaning
( Y
page 274)R
if the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on tech-
nical conditions.
i The rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens.
The flap closes again when: R
you have finished the maneuvering process R
you switch off the engine R
you open the trunk
Observe the notes on cleaning ( Y
page 274).
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated. Switching the rear view camera on/off X
To switch on: make sure that the Activa‐
tion by R gear function is selected in the
multimedia system (see Digital Operator's
Manual). X
Engage reverse gear.
The rear view camera flap opens. The multi-
media system shows the area behind the vehi-
cle with guide lines.
The image from the rear view camera is avail-
able throughout the maneuvering process. X
To switch off: shift the transmission to posi-
tion P .

of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions: R
very close to the rear bumper R
under the rear bumper R
in the area immediately above the tailgate
handle

ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/ h) to 125 mph
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It might not
always recognize fatigue or increasing inatten-
tiveness in time or fail to recognize 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 approx-
imately 30 minutes R
if the road condition is poor, e.g. if the surface
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 accel-
eration R
if you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h) R
if you are driving with the DISTRONIC PLUS
Steering Assist activated R
if the time has been set incorrectly R
in active driving situations, such as when you
change lanes or change your speed The attention level evaluation is deleted and
restarts when the journey is continued, if: R
you switch off the engine R
you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
In the assistance menu ( Y
page 195) of the on-
board computer you can call up the current sta-
tus information. X
Select the Assistance display for ATTENTION
ASSIST using the on-board computer
( Y
page 195).
The following information appears: R
length of the journey since the last break. R
the attention level determined by ATTENTION
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 warn-
ing, the System Suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer ( Y
page 196).
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 Attention
Assist is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the

When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated (stand-
ard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display: Attention Assist: Take a
Break!
In addition to the display message shown in the
multifunction display, you will then hear a warn-
ing tone. X
If necessary, take a break. X
Confirm the display message with the v
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take
a break, you will be warned again after
15 minutes at the earliest. This will only happen
if ATTENTION ASSIST still detects typical indi-
cators of fatigue or increasing lapses in concen-
tration.
Vehicles with COMAND multifunction dis-
play: if a warning is output in the multifunction
display, a service station search is performed in
the multimedia system. You can select a service
station and navigation to this service station will
then begin. This function can be activated and
deactivated in the multimedia system.
Traffic Sign Assist
General notes Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit.
Traffic Sign Assist is a map-based system, and
for this reason, traffic signs put up temporarily
(e.g. near roadworks) are not detected. There is
also no display for changing traffic signs.
If a traffic sign that is relevant to your vehicle is
passed, the display of the speed limits is upda-
ted.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown. The sign indicating the end of a restriction only
appears with the restriction in the instrument
cluster when: 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 avail-
able sources, no speed limit appears in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display C appears in the
assistance graphic ( Y
page 195).
Important safety notes Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.
