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 recognise other road users with their own lighting, or may recognise 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.

The Adaptive Highbeam Assist automatically switches between the following settings:

Low beam
High beam

The system detects that vehicle lights are approaching in the opposite direction or driving ahead of the vehicle.

At speeds greater than 30 km/h, the system will switch to the following setting:

If no other road users are detected, high beam will switch on automatically.

At speeds lower than 25 km/h or if there is sufficient street lighting, the system will switch to the following setting:

High beam will automatically switch off.

System limits

Adaptive Highbeam Assist cannot take the road, weather or traffic conditions into consideration.

The detection of obstacles may be restricted if:

visibility is poor, e.g. in fog, heavy rain or snow.
the sensors are dirty or covered.

Adaptive Highbeam Assist is only an aid. You are responsible for ensuring correct vehicle lighting in accordance with the prevailing light, visibility and traffic conditions.

The system's optical sensor is located behind the windscreen near the overhead control panel.
