Headlights
HeadlightsThe Adaptive Headlight (AHL) function is available as an option. It is offered in combination with the Bi-xenon headlights. This feature allows the low beam headlamps to swivel around the vertical axis. This means that the headlights can illuminate the curve of the road more effectively when negotiating bends.
Adaptive Headlights improve night-time visibility by continual adjustment of headlight aim to suit the curvature of the road. Illumination of the curve of the road allows the driver to follow its course more easily instead of having to drive into a "black hole." Dynamic headlamp aim adjustment improves peripheral awareness and reduces the risk of accidents.
1. Design feature (with bi-xenon headlights contains LEDs for side marker light)
2. Direction indicators
3. Reflector for low headlights
4. Fibre-optic ring lights for side lights
5. Reflector for high beam headlight
Halogen Headlights
The headlamp reflectors are framed by fiber-optic ring lights. The side light function is effected by the two reflectors. Above the direction indicators is a PCB with 6 LEDs and a fiber-optic tube to perform the side marker light function (not separately replaceable). The direction indicator function is performed by a 21 W long-life bulb.
For parking lights, a 5W bulb supplies the fiber-optic ring light and produces a hot spot in the lower part of the reflector.
The low beam headlight function is performed by an H7 long-life bulb in each of the outer reflectors.
The high beam headlight function is performed by an H7 long-life bulb in each of the inner reflectors.
The flash to pass simply uses the high beam light only.
Bi-xenon Headlights (optional)
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 beam height 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 (SIVICs) 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 detected by the zero position sensor (below the Bi-xenon bulb). The zero position is sensed by changes in incluctivity.
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 function (not separately replaceable).
For parking lights, the headlamp reflectors are framed by fiber optic ring lights. The ring lights are supplied by a 1 OW 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.
US-Version System Functions
The country-specific US version incorporates the following functions that differ from the EU version:
- High beam headlights. If Bi-xenon bulbs are fitted, the high beam headlight function is performed only by the Bi-xenon lights and not by the halogen lights in the inner reflectors.
- Daytime lights. The daytime lights function is performed by the fiber-optic ring lights.
Workshop Hints
The lens is permanently bonded to the headlight unit casing. The headlight units are adjustable along the x, y and z axes. Vertical adjustment of the headlight units is performed by the inner socket-head adjuster screws. Horizontal adjustment of the headlight units is performed by the outer socket-head adjuster screws.
^ The bulbs in the halogen headlights can be replaced with the headlight unit in place.
^ Replacement of the bulbs in the Bi-xenon headlights requires removal of the headlight unit.
Headlight Unit Removal and Installation
Note., It is suggested to mark the headlight location around the adjustment mounts and attaching screws before removal.
^ The headlight unit is removed by removing the top 2 screws from the front cross panel and the bottom 2 screws from the mounting bracket.
^ The headlight unit is removed forwards and then lifted upwards, detaching one main harness connection. The stepper motor for the Adaptive Headlights is replaceable.
^ For installation, the headlamps must first be adjusted and aligned with the side panels (slides in adjustment slots with bolts loose, up/dn adjustment by a threaded mount).The bumper trim panel is then aligned to the headlamp units.
