General information: Notes

Automatic vertical headlight aim control keeps the tilt angle of the low beams constant, even when vehicle tilt is different due to a load shift or acceleration/deceleration.

There is one level sensor at the front axle and one at the rear axle that register the vehicle's spring deflection. A signal proportional to vehicle speed is also processed by the ABS control module.

The control module evaluates these signals and activates the automatic vertical headlight aim control actuators when the lights are switched on.

Automatic vertical headlight aim control is required by law for vehicles with gas-discharge (xenon) headlights.
