Adaptive Highbeam Assist Plus - Mercedes-Benz S-Class Operator's Manual

The hazard warning lamps automatically
switch on if:
an air bag is deployed or
R
the vehicle decelerates rapidly from a
R
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 6 mph (10 km/h) again after a full
brake application.
The hazard warning lamps still operate if the
ignition is switched off.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the low-beam headlamps
are switched on.
Active:
if you are driving at speeds below 25 mph
R
(40 km/h) and switch on the turn signal or
turn the steering wheel
if you are driving at speeds between
R
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.

Adaptive Highbeam Assist Plus

General notes
With Adaptive Highbeam Assist Plus, you can
automatically switch between low-beam, par-
tial high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of
the high-beam. This prevents glare. When
there is a vehicle in front, for example, the
high-beam headlamps illuminate the areas to
its right and left, and the vehicle in front is
illuminated by the low-beam headlamps.
The system automatically adapts the low-
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 high-beam headlamps.
If the high-beam or partial high-beam are
causing too much reflection from traffic
signs, the lights are automatically dimmed
and glare for the driver caused by the reflec-
tions is thus avoided.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
