The dynamic headlight levelling control continuously and automatically adjusts the setting of the Xenon and Bi-Xenon headlights. This takes into account both the changes that are caused statically (load weight and distribution), as well as effects caused dynamically resulting from acceleration and deceleration.
The advantage of dynamic headlight levelling is that it compensates for the change in headlight range caused by the inclination of the car body during acceleration or braking, so the illuminated area remains virtually constant. This ensures good visibility for you while driving and helps to prevent dazzling oncoming traffic.
