following activation Adaptive Highbeam Assist
You can use this function to set the head-
lamp stoc hange between dipped beama nd
main beam automatically. The system recog-
nises vehicles with thei rlight son, either
approaching fro mthe opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. X
To activate: activate the Adaptive High-
beam Assist function using the on-board
computer (Y page 227).
X Turn the light switch to Ã.
X Press the combination switch beyond the
pressure point in the direction of arrow :
(Y page 116).
The _ indicator lamp in the instrument
cluster lights up if it is dark and the light
sensor activates the dipped-beamh ead-
lamps.
If you are driving at speeds above
45 km/h:
the headlamp range is set automatically
depending on the distanc ebetween the
vehicle and other road users.
If you are driving at speeds above
55 km/ha nd no other road users are rec-
ognised:
the main-beam headlamps are switched on
automatically. The Kindicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
45 km/ho rother road users are recog-
nised or the roads are adequately lit:
the main-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrument cluster goes out. The _
indicator lamp in the instrument cluster
stays on.
X To deactivate: move the combination
switch back to its normal position.
The _ indicator lamp in the instrument
cluster goes out. G

R
if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind acrash barrier
R on rare occasions :road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. Headlamps misted up inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
