ATTENTION ASSIST
Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might no
talways recognize fatigue
or increasing inattentiveness in time or fail to
recognize the matall. The system is not a
substitute for a well-rested and attentive
driver.
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria int oaccount:
R your personal driving style, e.g. steering
characteristics
R journey details, e.g. time of day and 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
surface 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 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R if you are currently using COMAND or
making a telephone call with it
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 X
Activate ATTENTION ASSIST using the on-
board computer (Y page 198).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the nhear an
intermittent warning tonet wice and the
Attention Assist: Drowsiness detected message appears in the
multifunction display.
X If necessary, take a break.
X Press the 000Bbutton to confirm the
message.
On long journeys, take regular breaks in good
time to allow yourself to res tproperly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
precondition for this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue yourj ourney 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.
The assistance graphic shows the 0002
symbol when ATTENTION ASSIST is
deactivated (Y page 197). Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 177) and Lane Keeping
Assist (Y page 178). 176
Driving systemsDriving and parking

Blind Spo
tAssist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterio rmirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding tur nsignal to change lanes,
you will also receive a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
For Blind Spot Assist to assist you, the radar
sensor system must be operational.
Important safety notes
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
sufficien tdistance to the side for other road
users and obstacles. G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing the minthe 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
carefully, and maintain a safe lateral distance.
i USA only:
This device has been approved by the FCC
as a "VehicularR adar 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 no tpermitted 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.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R 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
nextt
o 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. Driving systems
177Driving and parking Z

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 the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two rada rsensors 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
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 sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and 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. 0002
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp 0002in the exterior mirrors lights up
yellow at speeds of up to 20 mph (30k m/h).
At speeds above 20 mph (30 km/h), the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected withi nthe blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0002on the
corresponding 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
7mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
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 0002flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp 0002.There are no further warning tones.
Switching on Blind Spot Assist
X Make sure that Blind Spot Assist
(Y page 198) is activated in the on-board
computer.
X Turn the SmartKey to position 2in the
ignition lock.
Warning lamps 0002in the exterior mirrors
light up red for approximately
1.5 seconds and then turn yellow.
Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in
front of your vehicle with camera
0002, which is
mounted at the top of the windshield. Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. 178
Driving systemsDriving and parking

0002
Active Lane Keeping Assist camera
If you select km on the on-board computer in
the Display Unit Speed-/Odometer function (
Ypage 199), Lane Keeping Assist
is active starting at aspeed of 60 km/h. If the
miles display unit is selected, the assistance
range begins at 40 mph.
A warning may be given if a front wheel
passes over a lane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
Important safety notes
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an acciden tnor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely 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 your lane. G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, 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 stay in lane, in particular if
warned by Lane Keeping Assist. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
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 reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
R the lane markings are worn away, dark or
covered 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
detected
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 strong shadows cast on the lane
Switching on Lane Keeping Assist
X Switch on Active Lane Keeping Assist using
the on-board computer; to do so, select
Standard or
Adaptive (Y
page 198).
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected,
the lines in the assistance graphics display
(Y page 197) are shown in green. Lane
Keeping Assist is ready for use. Driving systems
179Driving and parking Z

Standard
If
Standard is selected, no warning vibration
occurs if:
R you switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
Adaptive
When Adaptive is selected, no warning
vibration occurs if:
R you switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, e.g.
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 lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when
necessary and in good time if you cross the
lane marking, the system recognizes 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
highway.
R the system recognizes 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 157),
Active Blind Spot Assist (Y page 180) and
Active Lane Keeping Assist (Y page 183).Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. Awarning
display in the exterior mirrors draws your
attentio nto 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
warning. If a risk of lateral collision is
detected, corrective braking may help you
avoid a collision. To support the course-
correcting brake application, Active Blind
Spot Assist uses the forward-facing radar
sensor system. The free space is then
evaluated in the direction of travel and to the
side before a course-correcting brake
application is initiated.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It does
not detect all traffic situations and road users
and is no substitute for attentive driving.
Always ensure that there is sufficient
distance to the side for other road users and
obstacles. G
WARNING
Active 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, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
