Xenon headlamps

Each headlamp (663 FL/FR) contains a 35 W Xenon bulb (D2S) with a 70 mm lens for dipped and main beam, corresponding ballast and ignition transformer. There is also an H7 halogen bulb that is used for main beam on certain markets. Xenon bulb optics shift between dipped and main beam image through a screen that drops down. The outer headlamp lens is plastic. Cars with Xenon lamps are equipped with automatic headlamp levelling.

When dipped beam is selected, only the xenon bulb for dipped beam (11a) lights. When main beam is selected, both the xenon and the main beam lamps light or the xenon lamp lights by itself, depending on the market. If the output of the halogen bulb exceeds 100 W, a DTC is generated in UEC and an error message is displayed in SID.
