The reasons why the Cruze's reverse radar does not beep include loose wiring, blown fuses, or damage to the radar module and buzzer. Below is an introduction to the reverse radar: 1. Concept: The full name of the reverse radar is "Reverse Anti-Collision Radar," also known as the "Parking Assistance Device," which serves as a safety aid during parking or reversing. 2. Components: It consists of ultrasonic sensors, a controller, a display, and other parts. 3. Function: While reversing, it informs the driver about surrounding obstacles through sound or a more intuitive display, eliminating the need for the driver to look around when parking, reversing, or starting the vehicle, and helps to eliminate blind spots and unclear vision, enhancing driving safety. 4. Blind Spots: The reverse radar also has certain blind spots, including obstacles that are too low (below 10~15cm from the center of the sensor), too thin, or ditches.
