Important safety notes G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others.
General notes ATTENTIO
NASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range. If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
ATTENTIO
NASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
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 sid ewind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND APS or
making a telephone call with COMAND APS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display Example: vehicles with automatic transmission
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the
nhear an inter-
mittent warning tone twice and the Atten‐ tion Assist: Drowsiness detected mes-
sage appears in the multifunction display. 208

board compute r(Ypage 241).
Symbol :appears in the multifunction
display.
X If necessary, take a break.
X Press the abutton to confirm the mes-
sage.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. 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 indicators of fatigue or increasing lap-
ses in concentration.
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. Speed Limit Assist
Important safety notes G
WARNING
Speed Limit Assist is only an aid and may
detec tspeed limit signs incorrectly or not at
all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees. R
the traffic signs are poorly illuminated.
R there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads.
Traffic signs always have priority over the
Speed Limit Assist display. Speed Limit Assist
cannot detect road and traffic conditions. It is
not a substitute for attentive driving.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. :
Speed Limit Assist camera
Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does not detec tany traffic
signs, the speed limit from the digital road
map is take nand shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen. Driving systems

General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 210) and Lane Keeping
Assist (Y page 212).
Blind Spot Assist Important safety notes
G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
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 monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For monitoring,
Active Blind Spot Assist uses sensors in the
rear bumper. 210
Driving systemsDriving and parking

For Blind Spot Assist to assist you whe
ndriv-
ing, the rada rsensor system must be activa-
ted (Y page 245) and operational.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 382).
Monitoring range of the sensors G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the nex tlane may no tbe detected, especially
if they are driving in a staggered formation in
differen tlanes .This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. Example: Coupé
Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly nextto
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 barrier sorsimilar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, 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 bumpe ris free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam-
age to the bumpers, have the function of the
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display G
WARNING
Blind Spot Assist is not active at speeds below
30 km/h. The indicator lamps in the exterior
mirrors are yellow. Vehicles in the monitoring
range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourselfa nd others. Driving systems

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 corre-
sponding side lights up red. This warning
always occurs when a vehicle enters the blind
spot monitoring rang efrom 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
deactivated.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If

Lane Keeping Assist Important safety notes
G
WARNING
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient 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. 212
