G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance. The use of the guide lines to judge
distance increases the risk of impacting the
objects.
Warning!
G
The Rear View Camera is a supplement sys-
tem. It is not intended to, nor does it re-
place, the need for extreme care. The
responsibility during parking and other driv-
ing maneuvers always remains with the driv-
er.
The Rear View Camera may show obstacles
with a distorted perspective, incorrectly or
not at all.
Special attention must be paid to objects
outside of the camera’s field of view such as
those located very close to or below the rear
bumper, or above the recessed grip of the
luggage compartment lid. Such objects may
not be detected by the system and can dam-
age the vehicle.
The Rear View Camera does not warn you
about impending collisions with objects. The
driver is always responsible for safety and
must continue to pay attention to the imme-
diate surroundings while parking or maneu-
vering the vehicle. This applies not only to
the area behind the vehicle, but also to the
area in front of and to the sides of the vehi-
cle. Failure to do so could result in injury to
persons and/or damage to the vehicle or
other property. We also recommend that the
driver uses the Parktronic system* or Park
Assist* when parking or maneuvering the
vehicle.

the rear of your vehicle is damaged. In
this case, have the position and setting
of the camera checked by a qualified
technician. Contact an authorized
Mercedes-Benz Center.
Do not use the Rear View Camera if the
roads are icy, slippery or covered with snow.
The vehicle could slip causing the actual ve-
hicle position to deviate from the one shown
on the COMAND display.
This may cause injury to you or others, or
damage the vehicle or objects.
Mounting tires/rims of other specification
than the original equipment tires/rims may
impair the function of the Rear View Cam-
era. Contact an authorized Mercedes-Benz
Center.

Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance as the use of the guide lines to judge
distance increases the risk of impacting the
objects.
Even when the object you approach is di-
rectly on the ground (and nothing on the ob-
ject extends above the ground beyond the
object’s contours directly touching the
ground) and no objects that do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck are in the path, do not ap-
proach the object on the ground any closer
than red guide line4.

Night View Assist*
Night View Assist illuminates the road with
infrared light in addition to the normal
headlamps.
A camera at the top of the windshield mea-
sures the infrared light and shows a
black-and-white image on the multifunc-
tion display. The image on the multifunction display cor-
responds to a road lit up by high-beam
headlamps.
The Night View Assist image on the multi-
function display is not impaired


by the headlamps of approaching vehi-
cles


if you cannot switch on the high beams
due to oncoming traffic
As a result, you can better follow the
course of the road and detect obstacles
earlier on.The camera is at the top of the windshield.

Switching on or off
You can only switch on the Night View As-
sist if

Warning!
G
Night View Assist is only an aid to support
you while driving and cannot substitute your
careful attention. Do not rely on the display
of the Night View Assist; instead, continue
to look through the windshield. You are al-
ways responsible for safety and must drive
in accordance with traffic conditions. Other-
wise, you could endanger yourself and oth-
ers.
If it is foggy, raining or snowing, the clarity of
the Night View Assist image on the multi-
function display may be diminished.
Warning!
G
Night View Assist cannot record objects im-
mediately in front of or next to the vehicle.
When maneuvering, continue to look
through the windshield. Make sure no per-
sons or animals are in the area in which you
are maneuvering. You could otherwise in-
jure them.
i
Infrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.

Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his/her primary focus when driving. For
your safety and the safety of others, stop be-
fore trying to remove window fogging or
cleaning the window in front of the Night
View Assist camera.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

Blind Spot Assist*
Blind Spot Assist uses radar sensors to
monitor the area on both sides of your ve-
hicle. It will assist you when you change
lanes driving at speeds of above 20 mph
(30 km/h). A warning will appear on the
outside rear view mirror as soon as anoth-
er vehicle is detected in the area being
monitored. If you then activate the corre-
sponding turn signals to change lanes, you
will see and hear a collision warning. Blind
Spot Assist operates using two sensors in
the front bumper and four sensors in the
rear bumper.In order for Blind Spot Assist to function,
the radar sensors must be switched on and
operational.
When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system. Canadian law
does not permit the use of the radar sensor
system for vehicles from outside of Cana-
da. When you switch off the radar sensor
system, the following functions are deacti-
vated:

Warning!
G
Blind Spot Assist is only a driving aid and
may not detect all vehicles. It is the driver’s
responsibility at all times to be attentive to
road, weather and traffic conditions and to
provide the steering, braking and other driv-
ing inputs necessary to retain control of the
vehicle. Failure to do so could result in
recognizing dangers too late, possibly re-
sulting in an accident and serious injury to
yourself and others.
Warning!
G
Blind Spot Assist cannot detect road and
traffic conditions.
Blind Spot Assist may not be able to detect
narrow vehicles such as motorcycles or bi-
cycles, or it may not detect them until it is
too late.
The monitoring function may be impaired if
your sensors are dirty, subject to heavy
spray, or if visibility is poor due to e.g. snow,
rain, or fog. This can result in vehicles not
being detected or being detected too late.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.

496 Controls in detailDriving systemsSensor monitoring range
Blind Spot Assist is able to monitor a range
up to three meters to the rear and both
sides of the vehicle.
The Blind Spot Assist sensors are built into
t h e f r o n t a n d r e a r b u m p e r s . M a k e s u r e t h a t
the area of the bumpers around the sen-
sors is free of dirt, ice and snow. The radar
sensors must not be obstructed, for exam-
ple, by bicycle carriers or overhanging lug-
gage.
Warning!
G
Blind Spot Assist monitors certain areas in
the immediate vicinity of your vehicle. Vehi-
cles approaching and passing at increased
speeds will not be detected. There will be no
warning display and no audible warning.
When driving in a very wide lane, the sensors
may not be able to cover the entire width of
the neighboring lane. Vehicles driving on the
outside of the neighboring lane may not be
detected.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
When driving in a very narrow lane, the sen-
sors may detect and display vehicles in the
second lane over. This will be the case if
there are vehicles driving on the inside edge
of their lane.!
In the event of a significant impact or dam-
age affecting the bumpers, have the radar sen-
sors checked by a qualified specialist workshop
such as a Mercedes-Benz Center. Failure to do
this can result in Blind Spot Assist not function-
ing correctly.
