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 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 may not
always detect fatigue or lapses in concentration
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 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 60 km/h or above 200 km/h
R if you are driving with the DISTRONIC PLUS
active steer 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 Driving systems
189Driving and parking Z

The evaluation of your attention level is deleted
and restarted when continuing the journey, 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 You can have current status information dis-
played in the assistance menu (Y
page 213) of
the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board com-
puter (Y page 213).
The following information is displayed:
R the 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
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 215).
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
À symbol and OFF appear in the multifunc-
tion display in the assistance graphics display
when the engine is running. When ATTENTION ASSIST has been deactivated,
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 concentration
are detected, a warning appears in the multi-
function display:
Attention AttentionAssist:
Assist:Take
Takea
a
break!
break!
In addition to the message shown in the multi-
function display, you will then hear a warning
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. 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 Online: 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 and overtaking restrictions to the
driver in the instrument cluster. Driving onto a 190
Driving systemsDriving and parking

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 over-
taking 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.
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 avail- able sources, no speed limit is displayed in the
instrument cluster either. Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (Y page 213).Important safety notes Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits and over-
taking restrictions. Traffic signs always have pri-
ority 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 windscreen
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 con-
struction sites or in adjacent lanes)
R the information in the digital street map of the
navigation system is incorrect or out of date
Switching the message function on/off If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
are displayed in the instrument cluster for five
seconds respectively. The wrong-way warning
and the traffic sign display for speed limits and
overtaking restrictions remain active even when
the display has been deactivated.

sign nor on the instrument cluster but must be
taken into account when observing the max-
imum permitted speed.
No entry (wrong-way warning) If no entry signs are passed, a warning message
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 immediately check
your direction of travel in order to avoid danger
to yourself and other road users.
i This function is not available in all countries. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 193) and Lane Keeping
Assist (Y page 195).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system to
monitor the areas on both sides of your vehicle.
It supports you from speeds of 30 km/h. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the moni- tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive an optical and audible collision
warning. For monitoring, Blind Spot Assist uses
sensors in the rear bumper. 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. Monitoring range of the sensors
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 bicycles
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. Driving systems
193Driving and parking Z

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 driv-
ing 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 driving
close to crash barriers or similar solid lane
borders
R warnings may be interrupted when driving
alongside long vehicles, for example lorries,
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 sensorsmust not be covered, for example by cycle racks
or overhanging loads. Following a severe impact or in the event of damage to the bumpers, havethe function of the sensors checked at a quali-
fied specialist workshop. Blind Spot Assist may
otherwise not work properly. Indicator and warning display :
Indicator lamp (yellow)
Warning lamp (red)
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yellow
up to a speed of 30 km/h. At speeds above
30 km/h, the indicator lamp goes out and Blind
Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the correspond-
ing side lights up red. This warning always
occurs 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.
The yellow indicator lamp goes out if reverse
gear is engaged. Blind Spot Assist is then deac- tivated.
The brightness of the indicator or warning lampsis adjusted automatically according to the ambi-
ent light.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones. 194

the exterior mirrors.
To do so, you will need to deactivate Blind
Spot Assist if:
R the key is in position 2in the ignition lock
R the engine is not running
R the electrical connection to the trailer has
been established
Lane Keeping Assist General notes
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 unintentionally.
This function is available within a speed 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.
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 Keep-
ing Assist can neither reduce the risk of an acci-
dent 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 responsible 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 vehicle in its lane.
The system may be impaired or may not functionif:
R there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area Driving systems
195Driving and parking Z

R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the road

Standard
If Standard
Standard is selected, no warning vibration
occurs if:
R you have switched on the turn signals. In this
case, the warnings are suppressed for a cer-
tain period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
Adaptive
When Adaptive
Adaptive is selected, no warning vibra-
tion occurs if:
R you have switched on the turn signals. In this
case, the warnings are suppressed for a cer-
tain period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system detects certain conditions and
warns you accordingly. The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend
R the road has very wide lanes, e.g. a motorway
R the system detects solid lane markings
The warning vibration occurs later if:
R the road has narrow lanes
R you cut the corner on a bend Active Driving Assistance package
General notes The Active Driving Assistance package consists
of DISTRONIC PLUS (Y page 161), Active Blind
Spot Assist (Y page 196)and Active Lane Keep-
ing Assist (Y page 199).
Active Blind Spot Assist General notes
Active 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 cor-
responding turn signal to change lanes, you will also receive a visual and audible collision warn-
ing. If a risk of side impact is detected, correc-
tive braking may help you avoid a collision.
Active Blind Spot Assist evaluates the free
space in the direction of travel and to the side
before making a course-correcting brake appli-
cation. 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. 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 196
Driving systemsDriving an
d parking

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 sideof 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 sen-
sors 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 otherwise no longer function prop-
erly.
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. 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 will then be
indicated late or not at all.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, 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 driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their
lane.
