General information

The automatic vertical headlight aim control system keeps the low beams at a constant level even if the car is loaded, a situation which would normally change the headlight angle.

There are two vehicle level sensors, one on the front axle and one on the rear axle. These sensors register the vehicle's fore/aft angle of inclination.

The control module processes the vehicle speed signal, evaluates the level sensor signals and turns the headlight beam adjusting motors on when the low beams are on.

The automatic vertical headlight aim control system is required for vehicles with gas discharge (Xenon) headlights.
