G Risk of accident
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
if there is poor visibility, e.g. due to snow,
R
rain, fog or spray
if the area of the windscreen around the
R
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
road users that have no lighting, e.g. pedes-
R
trians
road users that have poor lighting, e.g.
R
cyclists
road users whose lighting is not clearly visi-
R
ble, e.g. road users behind a crash barrier
on rare occasions: road users that have
R
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.
To activate: activate the Adaptive High-
X
beam Assist using the on-board computer
( page 120).

When the dipped-beam headlamps are
switched on, the _ indicator lamp in the
instrument cluster lights up.
If you are driving faster than 55 km/h and
no other road users are recognised, the
main-beam headlamps are switched on
automatically. The K indicator lamp in
the instrument cluster also lights up.
If you are driving slower than 45 km/h, if
other road users are recognised or if the
roads are adequately lit, the main-beam
headlamps are switched off automatically.
The K indicator lamp in the instrument
cluster goes out. The _ indicator lamp
in the instrument cluster stays on.
Adaptive control of the headlamp range
adjustment starts at a speed of approx-
imately 40 km/h.
To deactivate: move the combination
X
switch back to its normal position.
The _ indicator lamp in the instrument
cluster goes out.
