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.

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.

The Adaptive Highbeam Assist automatically switches between the following types of light:

Low beam
High beam

At speeds greater than 30 km/h:

If no other road users are detected, the high beam will be switched on automatically.

The high beam will switch off automatically in the following cases:

At speeds below 25 km/h.
If other road users are detected.
If street lighting is sufficient.

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