General description

Note

Before working on headlight with gas discharge lights and cor‐

nering lights, always switch off the headlights and remove the

ignition key.

When dealing with complaints, it is absolutely essential that

the function and operation of the lighting system are first un‐

derstood.

General description
The headlights with gas discharge bulbs and a cornering light

have a „bi-xenon“ feature.
With conventional xenon headlights, the gas discharge bulbs only

generate the dipped beam. The „bi-xenon“ features makes it pos‐

sible to generate both the dipped beam and the main beam with

„one“ gas discharge bulb. To achieve this, an electromechanical

adjuster ( left headlight screen adjustment solenoid -N395- / right

headlight screen adjustment solenoid -N396- ) uncovers the

screened area of the dipped beam on actuation of the main beam

function, thus producing main beam light distribution.
This means that with „bi-xenon“ headlights the main beam is al‐

ways automatically adjusted together with the dipped beam.
The headlights with gas discharge bulbs and cornering lights do

not have an „additional main beam“.
The cornering light has the following features:
♦ Swivelling main and dipped beams (dynamic cornering lights):

at vehicle speeds in excess of 10 km/h and steering turned.

♦ Cornering light bulb (static cornering light): when turning into

tight bends (bend radius smaller than 500 m) or when turning

a corner at vehicle speeds of less than 50 km/h

Fault detection and fault display
Automatic headlight range control, cornering lights and onboard

supply control unit are equipped with self-diagnosis.
For fault finding, use vehicle diagnosis, testing and information

system -VAS 5051B- in „Guided fault finding“ mode.
