Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
High-beam assistant: Introduction
The high-beam assistant assists the driver to operate the high-beam headlights. The high-beam assistant automatically switches the high-beam headlights on and off as the traffic situation changes.
The high-beam assistant detects vehicles travelling ahead of the car and oncoming traffic, and it also detects lighted stretches of roadway. By automatically switching off the high-beam headlights in good time, the highbeam assistant ensures that the occupants of oncoming vehicles, for example, are not dazzled by the headlights.
Advantages:
Drivers do not have to concern themselves with the job of operating the high-beam headlights. This enhances the level of convenience for drivers. The high-beam headlights are switched on more frequently by the high-beam assistant than is the case with manually operated high-beam headlights. The driver's field of vision is optimally illuminated. Driving in the dark, therefore, is rendered safer.
The high-beam assistant merely assists the driver in the task of operating the high-beam headlights.
Responsibility for switching the high-beam headlights on and off in accordance with the dictates of the traffic situation rests with the drivers.
The high-beam assistant can be deactivated at any time with the turn-signal/high-beam switch.

If a high-beam assistant is fitted, only the high beam of the bi-xenon headlights are switched on.
The halogen headlights are switched on only when the headlight flasher is actuated. In countries in which daytime driving lights are required by law, the halogen headlights are used for the daytime driving lights.
