Adjusting headlights with gas discharge lamps (Xenon)

Note:
If the basic setting cannot be set, check both axle sensors. When the vehicle is springs settled, the voltage values of the two sensors must be between 1.6 V and 3.5 V.
Before adjustment of headlights is performed on vehicles with gas discharge lamps, basic setting of the automatic headlight range control always must 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.
The vehicle must not be moved during the adjustment, to open/close doors or lean on vehicle is not allowed.
When headlights, vehicle level senders or headlight range control unit is renewed basic setting must be performed.
