Function, motorway lighting
At vehicle speeds exceeding 110 km/h, the AFL system will adjust the setting of the headlamp levelling stepper motors so that they are angled slightly
upward. When speed drops below 100 km/h, they will resume their normal setting. This function is designed to extend the illuminated distance slightly,
which helps to improve safety at higher speeds.
