Reply With QuoteThe main headlights with gas discharge bulbs and cornering lights (AFS = Adaptive Front Lighting System) have a “bi-xenon” function.
With conventional “xenon” headlights, the gas discharge bulbs only generate the dipped beam. The “bi-xenon” features makes it possible to generate both the dipped beam and the main beam with “one” gas discharge bulb. To achieve this, an electromechanical adjuster (left dip beam screen motor -V294- or right dip beam screen motor -V295-) 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 always automatically adjusted together with the dipped beam.
The main headlights with gas discharge bulbs and cornering lights do not have an “additional main beam”.
The cornering light system consists of the following functions:
Swiveling 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 < 500 m) or when turning a corner at vehicle speeds of less than 50 km/h
The cornering bulbs are a H7 55W and the Bi-Xenon is a D1S 35W. The parking bulbs are a H5W.
