Headlamp range adjustment (certain markets)

There are two motors on the reverse of the headlamps. These angle the headlamps upwards or downwards to control the range of the beam.

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