HID Headlamps With Cornering Lamp: 357
HID Headlamps With Cornering Lamp
• Before working on HID headlamps and cornering lamps, always switch off headlamps and bring ignition key or start button into position 0 (preliminary engaged position).
• Automatic Headlamp Range Control and cornering light in HID headlamps have On Board Diagnostics (OBD).
• Familiarity with the function and operation of the lighting system is essential in the event of customer complaints.
• Additional information:
refer to the Owner's Manual.
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 Low Beam Reflector Motor (V294) and Right Low Beam Reflector Motor (V295) ) 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.
HID headlamps with cornering lights do not have "auxiliary high beams".
The stationary cornering lamp illuminates when:
• Driving around tight curves with a curve radius less than 500 m (1640 ft.)
• Turning when the turn signal is activated and vehicle speed is between 10 and 40 km/h (6 and 25 mph).
In conjunction with the Rain/light recognition sensor (G397) , the stationary cornering lamp is only active when it is dark.
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.
The "Guided Fault Finding" function is to be used for troubleshooting of the systems as described in => [ Vehicle Diagnosis, Testing and Information Systems ] Vehicle Diagnosis, Testing and Information Systems.
• The indicator light "lamp failure" lights up in the instrument cluster when headlamp range control or AFS (Adaptive Front lighting System) system malfunctions. Refer to => [ Instrument Cluster ] Instrument Cluster.
• After performing work which can affect headlamp adjustment, check headlamp adjustment and adjust headlamps if necessary. Refer to => Maintenance Procedures.
