Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. byabarrier
In very rare cases, Adaptive Highbeam Assist
may fail too recognize other road users that
have lights, or may recognize them too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or activated regardless. There isarisk of an
accident.

You can use this function to set the
headlamps to change betweenlow beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detectsany other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.

Night View Assist Plus
Important safety notes
Night View Assist Plus is only an aid and is not
asubstitute 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:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthe windshield is dirty, fogged up or
covered, for instance byasticker, in the
vicinityofthe camera
Ron bends, on uphill gradients or downhill
gradients
Pedestrian recognition may be impaired or
inoperative if:
Rpedestrians are partially or entirely
obscured by objects, e.g. parked vehicles
Rthe silhouette of the pedestrian in the Night
View Assist Plus display is incompleteor
interrupted, e.g. by powerful light
reflections
Rpedestrians do not contrast adequately
from the background
Rpedestrians are not in an upright position,
e.g. sitting, squatting or lying
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
