The headlamp adjustment system ensures that the headlamps are always correctly angled on acceleration, braking and different loads. When the front of the vehicle is raised under strong acceleration, the headlamps are adjusted down and on strong braking, when the vehicle front is lowered, the headlamps are adjusted up. Also when the car is heavily loaded the headlamps are adjusted to the correct angle. The drive brake and vehicle speed influence the reaction time of the adjustment system.
The adjustment system is fitted with two load angle sensors placed on the front and rear axles.
