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 Plus 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.
Adaptive Highbeam Assist Plus cannot take into account road, weather or traffic conditions.
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 Plus is only an aid. You are responsible for ensuring correct vehicle lighting in accordance with the prevailing light, visibility and traffic conditions.
Low beam
