雷达控制系统同样在高车速时启动并通过自动加减车速来保持与其它车辆间的固定距离并在预见事故时发出警报。

Called Distronic, it also operates at high speed and adjusts both braking and acceleration to maintain a constant distance from other cars. If a collision seems likely a warning is given.

下雾时要叫我，鸣放汽笛，动用测深仪，启动一次雷达不要超过20分钟。

Call me when the fog set in. Sound regulation whistle, attend to echo sounding and start radar at an interval not more than 20 minutes.
