Adaptive Highbeam Assist
You can use this function to set the headlamps to change between low beam and high beam automatically. The system recognizes vehicles with their lights on, either approaching from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to low beam.
The system automatically adapts the lowbeam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it reactivates the high-beam headlamps.
The system's optical sensor is located behind the windshield near the overhead control panel.
•► To activate: activate the Adaptive Highbeam Assist function using the onboard computer.
•► Turn the light switch to 
or
.
•► Press the combination switch beyond the pressure point in the direction of arrow 1.
If it is dark and the light sensor activates
the low-beam headlamps, the 
indicator lamp in the instrument cluster
lights up.
If you drive faster than approximately 28 mph (45 km/h):
the headlamp range is set automatically depending on the distance between the vehicle and other road users.
If you drive faster than approximately 35 mph (55 km/h) and no other road users are identified:
the high-beam headlamps are switched on
automatically. The 
indicator lamp
in
the instrument cluster also lights up.
When you drive slower than approximately 30 mph (45 km/h) or if other road users are identified or if the roads are sufficiently illuminated:
the high-beam headlamps are switched off
automatically. The indicator lamp
in
the instrument cluster goes out. The
indicator lamp in the instrument cluster
stays on.
•► To deactivate: move the combination switch back to its normal position.
The indicator lamp in the
instrument
cluster goes out.
WARNING
The Adaptive Highbeam Assist is only an aid
intended to support you while driving. The
driver is and remains responsible for proper
vehicle lighting in accordance with the
prevailing light, sight and traffic conditions.
The system may be impaired or unavailable when
- visibility is poor, e.g. due to snow, rain, fog,
or heavy spray
- the optical sensor area of the windshield is
dirty, fogged up, or covered by a sticker for
example
The system cannot recognize the following road users:
- Road users without a lighting system of
their own, e.g. pedestrians
- Road users with dim lighting of their own,
e.g. cyclists
- Road users whose lighting is obstructed,
e.g. road users behind a guardrail
- In some seldom cases, even road users with
a lighting system of their own may be
recognized too late or not at all.
The automatic high-beam headlamps will then not be deactivated or it will be activated in spite of preceding or oncoming road users.
This could endanger you and/or others and cause an accident. Always pay close attention to the traffic situation and switch off the high beam manually if necessary.
