General Information

HID headlamps and cornering lamps have "Bi-Xenon" function.

Gas discharge lamps generate only the low beam headlamp in standard Xenon headlamps. "Bi-Xenon" allows "one" gas-discharge lamp to generate low beam and high beam headlamp. For this purpose, an electro-mechanical adjuster (Left headlamp Reflector Adjustment Solenoid (N395) and Right headlamp Reflector Adjustment Solenoid (N396)) opens the dimmed region of low beam headlamp when high beam function is operated and a high beam light emission results.

For this reason, the high beam is also adjusted automatically with the low beam on "Bi-Xenon" headlamps.

Headlamps with HID lamps and a cornering lamp do not have "auxiliary high beams".

Cornering lamps system performs the following functions:

• Swiveling low beams and high beams (dynamic cornering lamp) at vehicle speeds above 10 km/h and steering angle steer

• Cornering lamp bulb (static cornering lamp) at sharp curves (curve radius smaller than 500 m) or on turning-off and vehicles speeds below 50 km/h

DTC Recognition and Display

Automatic headlamp range control, cornering lamps and vehicle electrical system control are equipped with OBD.

Use the Vehicle Diagnosis, Testing and Information System (VAS 5051B) under "Guided Fault Finding".

• A malfunction in the range control or in the variable front lighting will be displayed in the instrument cluster by the lamp failure indicator lamp (K170).
