Adjusting of headlights with xenon lamps


Before the adjustment of the headlights is performed on vehicles with xenon lamps, a 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 a basic setting is not performed, the headlight range control device will be damaged.

Procedure:

  1. Read and check the inclination. The inclination value is embossed in trim above the headlight. It is stated in percentage and based on a projection distance of 10 metres. A value of for example 1,2 % corresponds to 12 centimetres.

  2. Select the basic setting: "Adjust light setting".

    • The headlights will now be moved into the adjustment position. This is confirmed with the text: "Activate".

  3. Adjust the headlights according to the national legislation and regulations.

  4. Exit the basic setting.

  5. Select the basic setting: "Store setting".

    • The new headlight setting is stored and the values from the front and the rear level sensors are stored as new starting values. This is confirmed with the text: "Control position learned".
