Bi-Xenon headlight, main and dipped beam (certain
variants only)
Xenon headlights produce roughly three times as much light as
halogen bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with Bi-Xenon headlights have automatic levelling. The level-
ling system comprises two sensors, one on the front suspension and
one on the rear suspension, and a control unit by the engine bay fuse
box. Headlight alignment is adjusted automatically to the car’s load
to prevent dazzling drivers in oncoming traffic.
If a fault is detected in the system, the following message will be dis-
played on the SID:
WARNING
Bi-Xenon headlights are high tension. All work on Bi-Xenon head-
lights, including changing bulbs, must be carried out by dealer
personnel.
