Automatic Headlight Levelling
Motors integrated in the headlights regulate the beam range of the headlights.
The motors adjust the headlights vertically depending on load and road conditions to reduce the risk of dazzle.
The motors are regulated via signals from one position sensor at the rear axle and one at the front axle.
The position sensor are directly connected to the "master" gas discharge lamp module (GDL). The sensors detect vehicle angle in different load conditions and transmit information to the "master" gas discharge lamp module (GDL), which then sends control signals to the motors regulating beam range.
If there is a fault in the automatic headlight levelling for the Bi-Xenon lamps, the actuator motors will automatically set the beam range to the shortest level.
There are diagnostics for the headlight levelling.
