in a limited manner:
R the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop.

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
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
