Adjusting headlights with xenon lamps


Before the adjustment of the headlights is performed on vehicles with xenon lamps, basic setting of the automatic headlight range control must always be carried out. The basic setting disconnects the control mechanism to make headlight adjusting possible. If basic setting is not performed the headlight range control device will be damaged.
