Ride-Height Sensors
The ride-height sensors supply the input signals for the headlight-range adjustment. One ride-height sensor is located on the right-hand side of the front axle. A ride-height sensor is located on the right of the rear axle.
The automatic headlight-range adjustment adapts the height adjustment of the headlights for different operating conditions (e.g. when laden, when braking and when accelerating in dynamic driving situations).
If the special equipment "Adaptive headlights" is fitted, the adaptive headlights control unit evaluates the signals from the ride-height sensors (AHL control unit). This is because: The AHL control unit also controls automatic headlight-range adjustment.
