driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.

Night View Assist Plus
General notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Camera ; of Night View Assist Plus picks up
the infrared light and displays a black and
white image in COMAND. The image shown 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.
When pedestrian recognition is active, pedes-
trians recognized by the system are visually
highlighted in color in the Night View Assist
Plus display with small frame corners.
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 traf-
fic.
