R
the trunk lid is open
R it is raining or snowing strongly or if it is
foggy
R it is night or if you are parking/
maneuvering your vehicle in a very dark
area
R a very bright white light is affecting the
camera
R the immediate vicinity is illuminated with
fluorescent light (the displa yofthe
COMAND system can flicker)
R 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.

Guide lines in the COMAND display G
WARNING
Use of rear view camera can be dangerous if
you are color-blind or have impaired color
vision.
Only use rear view camera if you can see and
distinguish all colored guidelines shown by
rear view camera on the COMAND system
display. G
WARNING
Please note that objects that do not touch the
ground may appear to be further away than
they actually are, for example:
R the bumper of a vehicle parked behind you
R the trailer drawbar
R the ball coupling of a trailer tow hitch
R the rear end of a truck
R a slanted post
In such cases, you should not use the guide
lines to judge the distance. You may misjudge
the distance, which increases the risk of
impacting the objects.
Even if the object you approach is directly on
the ground, do not approach the object any
closer than the red guide line. Example: information in the COMAND display
Guide lines
;and =show the approximate
distance to the rear area. Yellow guide
line ;indicates a distance of approximately
3 ft (1 m) and red guide line =indicates a
distance of approximately 10 in (0.25 m).The
distances only apply to objects that are at
ground level. Blue guide lines :depict the
width required for the vehicle. They are used
to align the vehicle with the edge of the road,
e.g. the curb. 320

function
Important safety notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road. The
Night View Assist Plus camera picks up the
infrared light and shows a black-and-white
image in the multifunction display. The image
shown in the multifunction 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. If
pedestrian recognition is activated,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
The spotlight function also illuminates
individual detected pedestrians with a
spotlight that flashes four times in quick
succession. After this targeted illumination,
the headlamps return to the original driving
position again. G
WARNING
Night View Assist Plus is only an aid designed
to assist driving. It is not a substitute for
attentive driving. Do not rely solely on the
Night View Assist Plus display. Continue to
look through the windshield. You are
responsible for safety and must drive in
accordance with traffic conditions .You could
otherwise put yourself and others in danger. The system may be impaired or unavailable if:
R
there is poor visibility, e.g. due to snow,
rain, fog or heavy spray.
R the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
R you are driving on bends, uphill gradients
or downhill gradients.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display .This
is also the case if you cannot switch on the
high-beam headlamps due to oncoming
traffic. G
WARNING
The Night View Assist Plus cannot record
objects immediately in front of or next to the
vehicle. When maneuvering, continue to look
through the windshield. Make sure no
persons or animals are in the area in which
you are maneuvering. You could otherwise
injure them.
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. :
