General notes Rear view camera
0043is in the trunk lid handle.
Rear view camera 0043is an optical parking and
maneuvering aid. It shows the area behind
your vehicle with guide lines in the COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display. Important safety notes The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R
if the trunk lid 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.
Observe the notes on cleaning
(Y page 358)
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the
vehicle (e.g. license plate holder, bicycle
rack).
i The rear view camera is protected from
raindrops and dust by means of a flap.
When the rear view camera is activated,
this flap opens.
The flap closes again when:
R you have finished the maneuvering
process
R you switch off the engine

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
ATTENTION ASSIST detects typical indicators
of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests taking a break.234
Driving systemsDriving an
d parking
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
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 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
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. Displaying the attention level You can have current status information
displayed in the assistance menu
(Y
page 259) of the on-board computer.
X Select the Assistance display for Attention
Assist using the on-board computer
(Y page 258).
The following information is displayed:
R length of the journey since the last break.
R the attention level determined by
ATTENTION ASSIST, displayed 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 Passive System Passive 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).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 261).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the 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. Driving systems
235Driving and parking Z
When ATTENTION ASSIST is deactivated, the
00AD symbol and OFF appear in the
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! 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
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
continues to detect 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.
If a warning is output in the multifunction
display, 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. Night View Assist Plus
General notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera 0044picks up
the infrared light and displays a monochrome
image in the multifunction display. The image
shown in the display corresponds to a road lit
up by high-beam headlamps. This enables you
to see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognized by the system
are visually highlighted in color in the Night
View Assist Plus display with small frame
corners.
i Infrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming
traffic.
In addition, thermal imaging camera 0043is
integrated in the radiator grill. The camera
helps detect pedestrians and animals.
Observe the notes on cleaning the thermal
imaging camera (Y page 359).
Important safety notes Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt236

General notes The Active Driving Assistance PLUS package
consists of DISTRONIC PLUS (Y page 201),
Active Blind Spot Assist (Y page 240) and
Active Lane Keeping Assist (Y page 243).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses 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. Active Blind Spot Assist
evaluates the free space in the direction of
travel and to the side before making a course-
correcting brake application. 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 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 240
