General description:
The AFS = adaptive headlight system with gas discharge lamps includes a bixenon „function“.
Gas discharge lamps on conventional „xenon“ headlights only generate light for dipped headlights. „Bixenon“ generates dipped headlights and main beam headlights with „one single“ gas discharge lamp. An electromechanical activator (left headlight screen adjustment solenoid -N395- or a right headlight screen adjustment solenoid -N396-) opens the dipped headlight area and distributes the main beam light when the high-beam function is activated.
For this reason, with „bixenon“headlights, when you adjust the dipped lights, the main beam also adjusts automatically.
The dynamic curve lighting system with gas discharge lamps do not have „additional main beam lights“.
The dynamic curve lighting system has the following functions:
t  adaptive dipped and main beam lights starting from 10 
km
h
and a steering angle when turning
t  Turning light on tight curves (curve radius < 500 m) or when veering at a speed of less than 50 
km
h
Detection and display of faults:
The automatic adjustable light range system, the dynamic curve lighting system and the onboard supply system have a self-diagnosis system that aids in locating faults in the main beam adaptive headlights with gas discharge lamps.
For fault location, use the function „guided fault location“ of the information, measuring and fault diagnosis system -VAS 505X-.
