• The system is a vehicle auxiliary device that can help the driver to safely change lanes while driving.
  
• During driving, when the side and rear vehicles are in danger of colliding with my car, the warning light will light up to remind the driver. If the left/right turn signal is turned on, it will be accompanied by an audible warning.
  
• The blind spot detection starts when the car starts. When you open the door, if there are pedestrians, cars and motorcycles on the side, it will be detected and accurately alarmed.
  
• The blind spot detection system can distinguish between stationary objects and moving objects. Stationary objects do not alarm. Pedestrians and vehicles in a driving state will sound an alarm when they are detected.
  
• When waiting for traffic lights: After parking, the car behind is still, and the blind spot detection system does not alarm.
  
• Normal driving: When the car behind is slower than us, there is no danger of collision and there is no warning. Similarly, when we overtake, the speed is faster than the car behind and there is no warning.
