of above 70 km/h and comes to a standstill

cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps from main beam to dipped beam. Once
the system no longer detects any other vehicles, it switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. Exterior lighting

Important safety notes

WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditionsand switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

other road users are recognised or the roads
are adequately lit:
