ATTENTION ASSIST
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 in the following situations:
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 contains potholes
R in case of strong side winds
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 DISTRONIC PLUS Steer-
ing 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 ASSIST tiredness assessment
is deleted and restarted when you continue the
journey in the following situations:
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 240) of the on-
board computer, you can call up the current sta-
tus information.
X Select the assistance graphic display for
ATTENTION ASSIST using the on-board com-
puter (Y page 239).
The following information appears:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST (Attention level Attention level), 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 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 242).
The system determines the attention level of
the driver depending on the setting selected:
If Standard Standard is selected: the sensitivity with
which the system determines the attention level
is set to normal.
If Sensitive
Sensitive is 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 on the multifunction dis-
play in the assistance graphic 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 Driving systems
207Driving and parking Z

corresponds to the last selection activated
(standard/sensitive).
Warning on the multifunction display If fatigue or increasing lapses in concentration
are detected, a warning appears on the multi-
function display: ATTENTION ASSIST ATTENTION ASSIST Take a

break!.
In addition to the message shown on 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 that allow
for adequate recuperation. If you do not take a
break and ATTENTION ASSIST still detects
increasing lapses in concentration, you will be
warned again after 15 minutes at the earliest.
This will happen only if ATTENTION ASSIST still
detects typical indicators of fatigue or increas-
ing lapses in concentration.
Vehicles with COMAND Online multimedia
system: if a warning appears on the multifunc-
tion display, a service station search is per-
formed in the multimedia system. You can
select a service station and you will then be
navigated to this service station. This function
can be activated and deactivated in the
COMAND Online multimedia system (see Digital Owner's Manual). Traffic Sign Assist
General notes Traffic Sign Assist displays the maximum speed
permitted and overtaking restrictions to the
driver on the instrument cluster. Driving onto a section of road in the wrong direction triggers a
warning. Traffic Sign Assist detects traffic signs with multifunction camera :attached at the
top of the windscreen. The data and general
traffic regulations stored in the navigation sys-
tem 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 in the following situations:
R The vehicle changes roads, e.g. motorway exit
or slip road
R A village or town boundary that is stored in the
digital map is passed
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 appears for five seconds. The currently
applicable traffic regulation continues to be
shown in the assistance graphic display
(Y page 239).
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in
wet conditions).
The traffic signs are displayed on the instrument cluster with the restrictions only in the following situations:
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 permissible speed from any of the
available sources, no speed limit is displayed on the instrument cluster either. 208
Driving systemsDriving and parking

Traffic Sign Assist is not available in all coun-
tries. In this case, the display :appears in the
speedometer.
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 in the following sit-
uations:
R Visibility is poor, e.g. due to snow, rain, fog or
spray
R Glare, e.g. from the sun being low in the sky
R Dirt, ice or misting on the windscreen in the
vicinity of the camera
R Traffic signs are hard to detect, e.g. due to
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 mes-
sage function in the on-board computer, the
traffic regulations (speed limits and overtaking
restrictions) are displayed on 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 deacti-
vated.
X Switch on the Traffic Sign Assist message
function via the on-board computer
(Y page 241).

; Maximum permissible speed for vehicles for
which the restriction in the additional sign is
relevant
= Additional sign for unknown restriction
A maximum permissible speed of 80 km/h
(80 mph) and a speed limit of 60 km/h( 60 mph)
with an unknown restriction apply.
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 on observance of the maximum
permissible speed.
No entry (wrong-way warning) A warning message
:is displayed on the
instrument cluster if Traffic Sign Assist detects
that you are passing a “no entry” sign and you
are driving in the wrong direction. You will then
also hear a warning tone. You should immedi-
ately check your direction of travel in order to
avoid danger to yourself and other road users. Driving systems

Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 210) and Lane Keeping
Assist (Y page 211).
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 lamp lights up on the exterior
mirror and 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 warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
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 not a 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 inte-
grated into the rear bumper. Make sure that the
bumpers are free of dirt, ice and slush. The sen- sors must not be covered, e.g. by cycle racks oroverhanging loads. Following a severe impact or in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali- fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
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 bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext to =and behind :your vehicle, as
shown in the picture.
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 the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time 210

Warning lamp
:
Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
The red warning lamp flashes on the relevant
exterior mirror. If the turn signal remains on,
detected vehicles are indicated by the flashing
of the red warning lamp on the exterior mirror.
There are no further warning tones.
Activating Blind Spot Assist
X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 241).
X Turn the key to position 2in the ignition lock.
The red warning lamps on the exterior mirrors
light up until the engine is started. Display in the Assist image
When Blind Spot Assist is activated, grey radar
waves propagating backwards appear next to
the vehicle in the Assist image on the multifunc-
tion display (Y page 239). Above a speed of
30 km/h, the colour of the radar waves in the
Assist image changes to green :. Blind Spot
Assist is then ready for use.
Towing a trailer
If you couple up a trailer, make sure that you
have correctly established the electrical con-
nection. This can be accomplished by checking
the trailer lighting. Blind Spot Assist is then
deactivated. The Blind Spot Assist not Blind Spot Assist not
available when towing a trailer See

Owner's Manual Owner's Manual message appears in the mul-
tifunction display.
Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :attached 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. Driving systems
211Driving and parking Z

This function is available in 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.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style 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 function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R 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
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 so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is very narrow and winding
R there are highly variable shade conditions on
the road surface

General notes The Driving Assistance PLUS package consists
of DISTRONIC PLUS (Y page 178), Active Blind
Spot Assist (Y page 213) and Active Lane Keep-
ing Assist (Y page 216).
Active Blind Spot Assist General notes
Using two lateral, rear-facing radar sensors,
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not visible to
the driver. A warning lamp lights up on the exte- rior mirrors and 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 warning. If a risk of side impact is detec- ted, a course-corrective brake application 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 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. 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 in 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 might otherwise no longer function prop-
erly. Driving systems
