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.
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. Driving systems
213Driving and parking Z

ATTENTION ASSIST assesses your level of
fatigue or lapses in concentratio nby taking
the following criteria into account:
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 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 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 wit hit
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 231).
Symbol 0002appears in the multifunction
display.
X The Attention Assist: Take a Break! message appears in the
multifunction display. If necessary, take
a break.
X Press the 000For001F button to confirm
the message. If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. In additio
nto the message
shown in the multifunction display, you will
then hear an intermittent warning tone twice.
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.
ATTENTION ASSIST is reset when you
continue 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. Active Driving Assistance package
General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y
page 186),
Active Blind Spot Assist (Y page 214) and
Active Lane Keeping Assist (Y page 218).
Active Blind Spot Assist Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no
substitute for attentive driving. 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 approaching and driving by with a
speed difference of more than
approximately 6.8 mph (11 km/h)
As a result, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is a risk of an accident. 214

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 lanes,
you will also receive an optical and audible
collision 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 also uses the forward-facing radar
sensor system. 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:
R
activated(Y page 235)
R operational
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 or snow.
R a narrow vehicle traveling in front, e.g. a
motorbike or bicycle.
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. Active Blind Spot Assist monitors the area up
to 10 ft
(3.0m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram .For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper. Driving systems
215Driving and parking Z

If the lanes are narrow, vehicles driving in the
lane beyond the lane next to yourv ehicle 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 warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Two Active Blind Spot Assist radar sensors
are integrated into the fron tand rea rbumpers
respectively. An additional radar sensor is
located behind the cover in the radiator grill.
Make sure that the bumpers and the cover in
the radiator grill are free of dirt, ice or slush.
The rear sensors must no tbe covered, for
example by cycle racks or overhanging cargo.
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
may otherwise no longer work properly.
Indicator and warning display 0002
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at
speeds below approximately 20 mph
(30 km/h). Vehicles in the monitoring range
are then not indicated.
When Active Blind Spot Assist is activated,
indicator lamp 0002in the exterior mirrors lights up yellow at speeds of up to
20 mph(30km/h). At speeds above 20 mph
(30km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30km/h), warning lamp
0002on the
corresponding side lights up red. This warning
is always given 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 (12km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Active Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Visual and acoustic collision warning When you switch on the turn signals to
change lanes and a vehicle is detected in the
side monitoring range, you receive a visual
and acoustic collision warning
.You then hear
a double warning tone and red warning
lamp 0002flashes. If the turn signal remains on,
detected vehicles are indicated by the
flashing of red warning lamp 0002.There are no
further warning tones. 216

Active Lane Keeping Assist Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor 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 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 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
General notes Active Lane Keeping Assist monitors the area
in front of your vehicle by means of
camera 0002at the top of the windshield. Active
Lane Keeping Assist detect slane markings on
the road and warns 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. 218
Driving systemsDriving and parking

If you select
km on the on-board computer in
the Display Unit Speed-/Odometer function (
Ypage 232), Active Lane Keeping
Assist is activated starting at a speed of
60 km/h. If the miles display unit is selected,
the assistance range begins at 40 mph.
Warning vibration in the steering wheel
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.
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
freeway.
R the system recognizes solidl ane markings.
The warning vibratio noccurs later if:
R the road has narrow lanes.
R you cut the corner on a bend.
Lane-correcting brake application G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake
application. G
WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate
brake application, e.g. afte rintentionally
driving ove rasolid lane marking. There is a
risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.
In rare cases, Active Lane Keeping Assist can
recognize unclear markings or particular
structures on the roadway as solid lane
markings. An inappropriate brake application
may be interrupted at any time if you steer
slightly in the opposite direction. If a lane-correcting brake application occurs,
display
0002appears in the multifunction
display.
If you leave your lane, under certain
circumstances the vehicle will brake briefly
on one side. This is meant to assist you in
bringing the vehicle back to the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can only
be made after driving over a solid,
recognizable lane marking. Before this, a
warning must be given by means of
intermittent vibration in the steering wheel.
In addition, a lane with lane markings on both
sides must be recognized. The brake
application also slightly reduces vehicle
speed.
i A further lane-correcting brake
application can only occur after your
vehicle has returned to the original lane. Driving systems
