Headlamp range adjustment (certain markets)

There are two motors, one on each headlamp, which angle the headlamps upwards or downwards to control the range of the beam. The motors are on the rear of the headlamps.

The motors are controlled by a thumb wheel which is located in the light switch module (LSM) on the dashboard by the side of the steering wheel.

If the thumb wheel is turned, information is transmitted to the motors which adjust the headlamps accordingly.

There are diagnostics for the headlamp range adjustment.
