The left front lamp unit and the right front lamp unit need to be adjusted, otherwise the light beam for illuminating the edge of the road blinds the oncoming traffic. This is done mechanically and must be performed when traveling to countries which have a different traffic routing (right-hand or left-hand traffic system).
Actuating the adjustment lever operates a moveable covering. The adjustment lever is located underneath the bulb for the low beam and can be accessed after opening the service flap and removing the cover of the housing of the left front lamp unit and right front lamp unit.
