General Description:

Main headlamps with gas-discharge lamps and cornering lamps (AFS = Adaptive Front lighting System) 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, high beam is also adjusted automatically with low beam for "Bi-Xenon" headlamps.

HID headlamps with cornering lamps do not have "auxiliary high beams".

The cornering lamp system has the following functions:

• Swiveling low beam and high beam (dynamic cornering lamp) from vehicles speeds above 10 km/h and steering wheel angle.

• Cornering lamp (static cornering lamp) at sharp curves (curve radius < 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 On Board Diagnostic (OBD) which assists troubleshooting of main headlamps with HID lamps and cornering lamps.

For troubleshooting, use Vehicle Diagnostic, Testing and Information System (VAS 5051A) in operating mode " Guided Fault Finding".

• Malfunction of the range control or AFS system are displayed in the instrument cluster with the "lamp failure" indicator lamp.
