ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.

WARNING
Night View Assist Plus does not detect
object sinthe immediate vicinit yofthe vehi-
cle. Look through the windscreen when
manoeuvring. Make sure that there are no
people or animals in the area in which you are
manoeuvring. In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera :picks up
the infrared light and display samonochrome
image in COMAND .The image displayed in
COMAND corresponds 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
are highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncomingv ehi-
cles does not affect the Night View Assist Plus
displayint he multifunction display. This is
also the case if you cannot switch on the main-beam headlamps due to oncomingt
raf-
fic.
i Infrared light is not visible to the human
eye and therefore does not dazzle. Night
View Assist Plus can therefore remain
switched on even if there is oncomingt raf-
fic.
Activating Night View Assist Plus Activation conditions
You can only activate Night View Assist Plus
if:
