Bi-xenon headlights
Bi-xenon headlights are installed with the
"XenonPlus" option.
The following lamps are fitted in the bi-xenon
headlight:
– A blue W5W lamp for the parking light.
The colour of the parking light thus corresponds
to the xenon light.
– A D2S lamp for high beam headlight, headlight
flasher and dipped beam headlight. The covers
for dipped beam are also activated for high beam
and headlight flasher operation.
– A P21W lamp for the daytime driving light.
This comes on dimmed to 90 %.
– A PY21W bulb coated with a reflecting layer of
silver is used as the direction indicator light.
Only longlife lamps are used. A super-longlife
lamp is used as the daytime driving light.
The following country-specific variants exist:
– No daytime driving lamp is fitted for Japan.
– 3457NA flasher lamps are used for USA and
Canada.
The headlights are changed over to left-hand drive
via a lever on the projection module.
A dynamic headlight range control system is
installed for bi-xenon headlights.
The dynamic headlight range control system uses
the well-known level sensors. This send the
information about the vehicle level to the control
unit for headlight range control J431 via a pulse
width-modulated signal.
The same level sensor is fitted on both the front and
rear axle.
Headlights are also available with dynamic
corner-sensitive lights.
