Adaptive Highbeam Assist Plus
General notes
With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed
past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main-
beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by
the dipped-beam headlamps.
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 switches on
the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf-
fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflections
is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Vehicles with drive program S+ (Sport Plus): the
speed at which Adaptive Highbeam Assist Plus
switches between full beam and dipped beam is
increased when the drive program is switched
on.
Important safety notes
G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
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

The
_
indicator lamp in the multifunction
display lights up when it is dark and the light
sensor switches on the dipped-beam head-
lamps.
At speeds above approx.25 km/h: the
headlamp range is automatically controlled
according to the distance to other road users.
At speeds above approx.30 km/h:
R
if no other road users are detected, the
main-beam headlamps are automatically
switched on
R
if other road users are detected, the partial
main-beam headlamps are automatically
switched on
The
K
indicator lamp in the instrument
cluster also lights up.
At speeds below approx.25 km/hor when
there is sufficient street lighting:
R
the partial main-beam headlamps are
switched off automatically
R
the main-beam headlamps are switched off
automatically
