GWARNING
The rear view camera is only an aid, and may
display obstacles:
R from a distorted perspective
R incorrectly
R not at all.
The rear view camera does not relieve you of
the responsibility to take care. Take all
necessary care and pay particular attention to
the traffic conditions. The rear view camera
may not show objects that:
R are very near to the rear bumper
R are underneath the rear bumper
You are responsible for safety at all times and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of, and next to the vehicle. You could
otherwise put yourself and/or others in
danger.
GWARNING
The rear view camera does not work or does
not work properly if:
R it is raining heavily or if it is snowing or
foggy.
R it is night or if you are parking/
maneuvering your vehicle in a very dark
area.
R very bright white light is shining on the
camera.
R the immediate vicinity is illuminated with
fluorescent light (the display of the
COMAND system can flicker).
R the temperature changes abruptly, for
example if you drive out of the cold into a
heated garage (condensation on the lens).
R the camera lens is dirty or covered.
R the rear of your vehicle is damaged.
In this case, have the position and the
setting of the camera checked at a
specialist workshop. Mercedes-Benz
recommends that you consult a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. You could otherwise injure
yourself and other people and/or cause
damage - including damage to your vehicle -
while parking/maneuvering.
Activating the rear view cameraXEnsure that key position 2 has been
selected with the Start/Stop button.XMake sure that the "rear view camera"
function is selected in COMAND (see the
separate operating instructions for
COMAND).XEngage reverse gear.

You can also switch off the display of the area
behind the vehicle in the COMAND display.
Blind Spot Assist
Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It assists you from a speed of
approximately 20 mph(30 km/h). 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
collision warning. For this purpose, Blind Spot
Assist uses sensors in the rear bumper.
GWARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some
vehicles and is no substitute for attentive
driving.
Blind Spot Assist cannot detect road and
traffic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
Driving systems143Driving and parkingZ
Page 146 of 288

rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
i USA only:
This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
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
Blind Spot Assist monitors the area illustrated
up to 10 ft (3 m) behind and directly next to
your vehicle.
Example (Roadster)
GWARNING
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be
possible to monitor the complete width of the
neighboring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
that edge of their lane which is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
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 the vehicles are driving on the
inner side 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 warnings may be interrupted when driving
alongside particularly long vehicles, for
example trucks, for a prolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free from dirt,
ice or slush around the sensors. The radar
sensors must not be covered, e.g. by
overhanging loads. 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.
Blind Spot Assist may otherwise not work
properly.144Driving systemsDriving and parking

Indicator and warning display:Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp : lights up yellow in the exterior
mirrors up to a vehicle speed of 20 mph
(30 km/h). From a speed of approximately
20 mph (30 km/h) the indicator lamp goes out
and Blind Spot Assist is operational.
If a vehicle is detected in the monitoring range
of Blind Spot Assist from a speed of
approximately 20 mph(30 km/h), warning
lamp : lights up red on the corresponding
side. 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 is only given
if 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, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
GWARNING
Blind Spot Assist is not active at speeds under
approximately 20 mph (30 km/h). The
indicator lamps in the exterior mirrors are
yellow. Vehicles in the monitoring range are
then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp : flashes. If
the turn signal remains on, detected vehicles
are indicated by the flashing of red warning
lamp :. There are no further warning tones.
Switching on Blind Spot Assist
XMake sure that Blind Spot Assist
( Y page 156) is activated in the on-board
computer.XEnsure that key position 2 has been
selected with the Start/Stop button.
Warning lamps : light up red in the
exterior mirrors for approximately
1.5 seconds and then turn yellow.Driving systems145Driving and parkingZ

GWARNING
A driver's attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h ), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
GWARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
