The headlights auto leveling system is composed of the headlight auto leveling control unit, the front and rear headlight leveling sensors, and the left and right headlight leveling motors.

The system monitors the vehicle posture from the front and rear leveling sensor every 3 minutes while the vehicle is running constantly with the headlight switch ON, and after 8 seconds from the vehicle stops with the ignition switch and headlight switch ON.

If the control unit detects the posture change of the vehicle, the control unit controls the headlight leveling motors to adjust the headlight vertical position.
