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 ATTEN-
TION ASSIST detects typical indicators of fati- gue 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 to the
driver. It might not always recognize fatigue
or increasing inattentiveness 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
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 slower
than 37 mph (60 km/h) or faster than
125 mph (200 km/h)
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 ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again 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 244)
of the on-board computer.
X Select the Assistance display for Attention
Assist using the on-board computer
(Y page 243).
The following information is displayed: R 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.
R If ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System SystemSuspended
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). 216

Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 246).
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 Atten- tion Assist is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the 00D7 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 stopped. 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 0076
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minute sat 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 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. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 217) and Lane Keeping
Assist (Y page 219).
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 mirrorsdraws 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 warn- ing.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/h).
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
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. Driving systems

USA only:
This device has been approved by the FCC as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
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 area
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R there is poor visibility, e.g. due to fog, heavy
rain, snow or spray
R there are narrow vehicles, e.g. motorcycles
or bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not indicated. Blind Spot Assist monitors the area up to 10 ft
(3 m) behind 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 driving at the
inner edge of their lanes.
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 the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
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 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. 218

Warning display
0043
Warning display
Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0043on the corre-
sponding side lights up red. This warning is
always emitted 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 7 mph (12 km/h).
If you select the reverse gear, Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings.
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 0043flashes. If
the turn signal remains on, vehicles detected
