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 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

General notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Camera 0044of Night View Assist Plus picks up
the infrared light and displays a black and
white image in COMAND. The image shown
in COMAND 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. 214
Driving systemsDriving and parking
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 and cleaning the windshield
(Y page 552).
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 adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
R if the thermal imaging camera in the
radiator grill is dirty, fogged up or covered
R on bends, hilltops or downhill gradients
R at high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle. The
actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
It may be the case that other objects are
marked or highlighted as well as pedestrians
and animals. Pedestrian and animal recognition General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
R
pedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
R the silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by
powerful light reflections
R pedestrians or animals do not contrast with
the surroundings
R the camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying
R animals are not recognized by the system,
e.g. because of their size or shape
The pedestrian and animal recognition is
deactivated at temperatures above 90 ‡
(32 †). The spotlight function and automatic
delayed switch-off are then no longer active.

General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y
page 186),
Active Blind Spot Assist (Y page 218) and
Active Lane Keeping Assist (Y page 221).
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. 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 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 operational.
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 which approach with a large speed
differential and overtake your vehicle 218
Driving systemsDriving and parking
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.

integrated into the front and rear bumpers
and behind a 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 not be covered, for
example by cycle racks or overhanging cargo.

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. Monitoring area 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. 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 monitoring range 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 driving at the
inner edge of their lanes. Driving systems
219Driving 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 warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Indicator and warning display 0043
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 0043in the exterior mirrors lights
up yellow at speeds of up to
20 mph(30 km/h). At speeds above 20 mph
(30 km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0043on 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 7 mph (12 km/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
0043flashes. If the turn signal remains on,
detected vehicles are indicated by the
flashing of red warning lamp 0043. There are no
further warning tones.
Course-correcting brake application G
WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides. 220
Driving systemsDriving an
d parking
If a course-correcting brake application
occurs, red warning lamp 0043flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display 0044appears in the
multifunction display.
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate. R
a driving safety system intervenes, e.g.
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is switched off.
R a loss of tire pressure or a defective tire is
detected.
