Bi-xenon headlights are only available as an option in combination with the Adaptive
Headlights feature (for additional detailed information, refer to AHL section). A dynamic
beamheight adjustment function is also incorporated in the Bi-xenon headlight package.
The Bi-xenon bulbs are fitted in the outer reflectors. On each Bi-xenon headlight there is a
stepper motor for adjusting the position of the Bi-xenon bulb. The Bi-xenon control units
and the stepper motor controllers (SMCs) are located next to each other on the underside
of the headlamp units.
The stepper motors are not fitted with motor position sensors, the zero position is detect-
ed by the zero position sensor (below the Bi-xenon bulb). The zero position is sensed by
changes in inductivity.
The direction indicator function is performed by a 21W long-life bulb. Above the direction
indicators is a PCB with 6 LEDs and a fiber-optic tube to perform the side marker light func-
tion (not separately replaceable).
For parking lights, the headlamp reflectors are framed by fiber-
optic ring lights. The ring lights are supplied by a 10W bulb with
a reflector. The reflector is in the headlamp unit near the high
beam headlight.
The low beam headlight function is performed by a Bi-xenon
bulb (D2S) in each of the outer reflectors. The Xenon control unit
controls the Bi-xenon bulb function (low beam/high beam).
The high beam headlight function is performed only by the Bi-
xenon lights and not by the halogen lights in the inner reflectors.
In each inner reflector there is an H7 long-life bulb, which is used
for the flash to pass function.
