Mercedes-Benz GLC : Operating the combination switch for the lights / Adaptive Highbeam Assist
Adaptive Highbeam Assist function
WARNING Risk of accident despite
Adaptive Highbeam Assist
Adaptive Highbeam Assist does not react to:
- Road users without lights, e.g. pedestrians
- Road users with poor lighting, e.g.
cyclists
- Road users whose lighting is obstructed,
e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
with their own lighting, or may recognize
them too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or
will be activated despite the presence of
other road users.
Always observe the road
and traffic
conditions carefully and switch off the
high beam in good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Detection may be restricted in the following
cases:
- In poor visibility, e.g. fog, heavy rain or snow
- If there is dirt on the sensors or the sensors
are obscured
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting to
the prevailing light, visibility and traffic conditions.

Adaptive Highbeam Assist automatically
switches between the following types of light:
At speeds greater than 19 mph (30 km/h):
- If no other road users are detected, the high
beam will switch on automatically.
The high beam will switch off automatically in
the following cases:
- At speeds below 16 mph (25 km/h)
- If other road users are detected
- If street lighting is sufficient
The system's optical sensor is located
behind the windshield near the overhead
control panel.
