214 Car care Xenon headlight, dipped beam (certain variants only) WARNING Xenon headlights are high tension. All work on xenon headlights, including changing bulbs, must be carried out by dealer personnel. Xenon headlights produce roughly two times as much light as halogen bulbs and have a significantly longer service life. The lamp units consist of a gas discharge lamp containing xenon. When the lights are switched on a very high voltage activates the xenon gas. The lamps soon reach full intensity. Cars with xenon headlights have automatic levelling. The levelling system is comprised of two sensors, one on the front suspension and one on the rear suspension, and a control unit by the engine bay fuse box. Headlight alignment is adjusted automatically to the car's load to prevent dazzling drivers in oncoming traffic. If a fault is detected in the system, the following message will be displayed on the SID: Headlight levelling malfunction. Contact Saab dealer. Contact a Saab dealer to have a xenon headlight changed
