Note usage and safety notes for gas discharge headlamps --> [ HID Headlamps Safety Precautions ] HID Headlamps Safety Precautions
• Always switch off headlamps with gas-discharge lamps and remove ignition key before working on headlamps.
• Automatic vertical headlamp aim control of headlamps with gas-discharge lamps has On Board Diagnostics (OBD).
• Familiarity with the function and operation of the lighting system is essential in the event of customer complaints.

General Description:
Main headlamps with gas-discharge 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, high beam is also adjusted automatically with low beam for "Bi-Xenon" headlamps. If "auxiliary high beam headlamp" is installed, it can be adjusted separately.
North American models:
Low beam headlamp is generated by one light source:
• Left High Intensity Gas Discharge (HID) Lamp (L13) ("Bi-Xenon") and Right High Intensity Gas Discharge (HID) Lamp (L14) ("Bi-Xenon")
High beam headlamp is generated by one light source:
• Left High Intensity Gas Discharge (HID) Lamp (L13) ("Bi-Xenon") and Right High Intensity Gas Discharge (HID) Lamp (L14) ("Bi-Xenon")
High beam headlamp (flasher with ignition switched off) is generated by one light source:
• Left High Beam headlamp (M30) and Right High Beam headlamp (M32) ("auxiliary high beam headlamp")
DTC recognition and display:
Automatic vertical headlamp aim control and vehicle electrical system control are equipped with On Board Diagnostic (OBD) which assists troubleshooting of main headlamps with gas-discharge lamps.
For troubleshooting, use Vehicle Diagnostic, Testing and Information System (VAS 5051A) in operating mode " Guided Fault Finding".
