1. The front vehicle collision warning is an active safety technology. When the potential collision danger between the vehicle and the preceding vehicle is detected, it will be reminded to prevent or reduce the injury caused by rear-end collision.

2. The front radar is used to detect the distance of obstacles in front of the car when the car is parked or driving slowly (less than 15 km/h), provide information such as the distance, orientation and area of obstacles, and give an alarm in time.
