Adaptive headlight range control
The adaptive headlight range control feature balances out acceleration and braking processes as well as the vehicle load conditions in order to avoid dazzling oncoming traffic. Illumination of the road is optimized.
High-beam Assistant
Concept
The high-beam Assistant detects other traffic participants early on and automatically switches the high beams on or off depending on the traffic situation.
General information
The high-beam Assistant ensures that the high beams are switched on, whenever the traffic situation allows. In the low speed range, the high beams are not switched on by the system.
The system responds to light from oncoming traffic and traffic driving ahead of you, and to ambient lighting, for instance in towns and cities.
The high beams can be switched on and off manually at any time.
Activating/deactivating

Position of switch, depending on the vehicle equipment:
,
Press the button on the turn signal lever.

The indicator light in the instrument cluster is illuminated when the low beams are switched on.
The headlights are automatically switched between low beams and high beams.

The blue indicator light in the instrument cluster lights up when the system switches on the high beams.
The high-beam Assistant is deactivated when manually switching the high beams on and off.
To reactivate the high-beam Assistant, press the button on the turn signal lever.
System limits
The high-beam Assistant cannot serve as a substitute for the driver's personal judgment of when to use the high beams. In situation that require this, therefore switch off manually.
The system is not fully functional in the following situations, and driver intervention may be necessary:
- In very unfavorable weather conditions, such as fog or heavy precipitation.
- When detecting poorly-lit road users such as pedestrians, cyclists, horseback riders and wagons; when driving close to train or ship traffic; and at animal crossings.
- In tight curves, on hilltops or in depressions, in crossing traffic or half-obscured oncoming traffic on highways.
- In poorly-lit towns and cities and in the presence of highly reflective signs.
- When the windshield in front of the interior mirror is fogged over, dirty or covered with stickers, etc.
