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:
Standard selected: the sensitivity with
which the system determine sthe 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
0002 symbol and OFF appearint he
multifunction display in the assistance
display when the engine is running.
When ATTENTION ASSIST has been
deactivated, 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
concentration are detected, a warning
appears in the multifunction display:
Attention Assist: Take a Break! In addition to the message shown in the
multifunction display, you will then hear a
warning tone.
X If necessary, take a break.
X Confirm the message by pressing the
000B 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
concentration, 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
lapses in concentration. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 221) and Lane Keeping
Assist (Y page 223).
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 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.
Important safety notes 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.
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.

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 no tdriving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. Example
:Coupe
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
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 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
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.

Active Driving Assistance package
General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y page 191),
Active Blind Spot Assist (Y page 225) and
Active Lane Keeping Assist (Y page 228).
Active Blind Spot Assist General notes
Active Blind Spot Assis
tuses a radar sensor
system, pointed toward the rear of the
vehicle, to monitor the area to the sides of the
vehicle which the driver is unable to see. 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
warning. If a risk of lateral collision is
detected, corrective braking may help you
avoid a collision. Before acourse-correcting
brake application, Active Blind Spot Assist
evaluates the space in the direction of travel
and at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (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 detect all
traffic situations and road users .There is a
risk of an accident.
Always make sure that there is sufficient
distance on the side for other traffic or
obstacles. Example: Coupe
Active Blind Spot Assist monitors the area up
to 10 ft (3.0 m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram.
The detection of obstacles can be impaired in
the case of:
R
dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoringr ange are then not
indicated or indicated with a delay.
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
driving in the middle of their lane .This may be the case if there are vehicles at the edge
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 lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such

Active Lane Keeping Assist
General notes
Active Lane Keeping Assis
tmonitors the area
in front of your vehicle by means of camera
system 0002at the top of the windshield.
Various different areas to the front, rear and
side of your vehicle are also monitored with
the aid of the radar sensor system. Active
Lane Keeping Assist detect slane markings on
the road and can warn you before you leave
your lane unintentionally. If you do no treact
to the warning, a lane-correcting application
of the brakes can bring the vehicle back into
the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of acciden tnor override the laws of
physics. Active Lane Keeping Assist cannot
take account of road and weather conditions.
It may not recognize traffic situations. Active
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 your lane.
Active Lane Keeping Assist cannot
continuously keep your vehicle in its lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you.
Terminate the intervention in a non-critical
driving situation.
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 the radar sensors in the front or rear
bumpers or the radiator grill are dirty, e.g.
obscured by snow
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 228
