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 speed 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.
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 272
Driving systemsDriving and parking

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
The ATTENTION ASSIST tiredness assess-
ment is deleted and restarted when continu-
ing the 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 327)
of the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board
computer (Y page 326).
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

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 329).
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).
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 Driving systems

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 326).
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. 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 274

rking

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 327).
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 in the Assist graphic even
when the display has been deactivated.

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) If no entry signs are passed, a warning mes-
sage is displayed in the instrument cluster
should Traffic Sign Assist detect that you are
driving in the wrong direction. You will then
also hear a warning tone. You should imme-
diately 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 276) and Lane Keeping
Assist (Y page 279).
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. 276
Driving systemsDriving and parking

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 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 Driving systems
