How to Use a Car Rearview Camera?

Method for using a car rearview camera: The rearview camera mainly displays three lines—red, yellow, and green. The front line is red, the middle line is yellow, and the rear line is green. Stop immediately if the red line indicates 30cm; be cautious when the yellow line shows a distance of about 0.7 meters, and gently release the brake while reversing; the green line indicates a distance of approximately 2 meters, meaning the car is far from obstacles, allowing you to turn around or continue reversing. A car rearview camera is a system that provides intuitive and clear rearview images, offering great convenience to drivers. It enables real-time monitoring of the areas on both sides and behind the car, helping to prevent accidents and theft.
When I first started driving, the rearview camera was my best helper. After shifting to R gear, the central control screen automatically displayed a real-time view of the rear, usually showing a green zone for safe distance, yellow for caution, and red as a warning to stop. Every time I used it, I would first glance around through the rearview mirror to ensure no people or cars were nearby, then slowly reverse while watching the screen, as the camera angle is limited and might miss the sides of the car. Last time in the parking garage, I almost scraped a pillar because I was only staring at the screen and forgot to check the side mirrors. Since then, I’ve developed a habit of multiple checks. Beginners are advised to practice in open spaces, familiarize themselves with the meaning of the guiding lines, and not let the camera replace basic observation. Also, the lens can easily get covered in dirt, so cleaning it weekly keeps the image clear. This tool greatly boosts confidence in reversing, but safety always comes first—don’t forget to develop your skills in spotting blind spots.
