Night View Assist Plus
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 displays a grayscale image
in the COMAND display. The image displayed
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. If pedestrian recognition is
activated, pedestrians recognized by the
system are highlighted in the Night View
Assist Plus display.

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:
there is poor visibility, e.g. due to snow,
R
rain, fog or heavy spray.
the windshield is dirty, fogged up or
R
covered, for instance by a sticker, in the
vicinity of the camera.
you are driving on bends, uphill gradients
R
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.

WARNING
The Night View Assist Plus cannot record
objects immediately in front of or next to the
