tView Assist Plus
Important safet ynotes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminat
ethe road. The
Night View Assist Plus camer apicksupt he
infrared light and displays amonochrome
image in COMAND. The image displayed in
COMAN Dcorresponds to aroad lit up by
main-beam headlamps. This enables you to
see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognised by the system
ar eh ighlighted in the Night View Assist Plus
display. G
WARNING
Night View Assist Plus is only an aid designed
to assist driving and does not relieve you of
the responsibility to pay attention. Continue
to look through the windscreen instead of

rain, fog or spray.
R the windscreen is dirty, misted up or cov-
ered, for instance by asticker, in the vicinity
of the camera.
R on bends ,onuphill gradients or downhill
gradients.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multifunction display. This is
also the case if you cannot switch on the
main-beam headlamps due to oncomin gtraf-
fic. G
WARNING
Night View Assis tPlus does not detect
object sinthe immediat evicinity of the vehi-
cle. Look through the windscreen when

Pedestrian recognition G
WARNING
Pedestrian recognition may be impaired or
inoperative if:
R pedestrians are partiall yorentirely
obscured by obje cts, e.g. by parked vehi-
cles.
R the silhouett eofthe pedestrian in the Night

interrupted, e.g. by powerful ligh treflec-
tions.
R pedestrians do not contrast with the sur-
roundings.
R pedestrians are not in an upright position,
e.g. sitting, squattin gorlying.
i Animals are not recognised by pedestrian
recognition.
Night View Assist Plus is able to recognise
pedestrians by typical characteristics, e.g. a
silhouette in the shape of aperson.

R you are driving faster than about 10 km/ h.
R the surrounding sare dark ,e.g.w hen driv-
ing outside built-up areas without street
lighting.
If pedestrian recognition is active ,sym-
bol ?appears. If apedestrian is now recog-
nised, they are framed =and thereby high-
lighted. If the pedestrian recognition system
has brought apedestrian to your atten tion,
look through the windscreen to evaluate the
situation .The actual distanc etoobjectsand
pedestrians cannot be gauged accurately by
looking at ascreen.
