加分求助，关于【headlight range control】

本帖最后由 thx1 于 2014-8-10 16:36 编辑 your vehicle is equipped with a headlight range control to prevent oncoming traffic from being dazzled when the vehicle is heavily laden.
headlight range control 有4档0，1，2，3
0-one or two front occupants, luggage compartment empty
1-all seats occupied, luggage compartment empty
2-all seats occupied, luggage compartment loaded
3-driver only, luggage compartment loaded
请问为什么前车灯的照射范围跟车上的乘客数量还有是否放行李有关？谢谢
