Driving tipsDriving and parking

ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness agai nif:
R you switch off the engine.
R you take off you rseat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Night View Assist Plus
Important safety notes Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
R on bends, on uphill gradient sordownhill
gradients
Pedestrian recognition may be impaired or
inoperative if:
R pedestrians are partially or entirely
obscured by objects, e.g. parked vehicles
R the silhouette of the pedestrian in the Night
View Assist Plus display is incomplete or
interrupted, e.g. by powerful light
reflections
R pedestrians do not contrast adequately
from the background
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying General notes
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
0002picks up
the infrared light and displays a monochrome
image in COMAND. 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.
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.
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.
Activating Night View Assist Plus Activation conditions
