How to Interpret the Guidelines on a Reversing Camera Display

[DeAllison]

Here is information about the guidelines on a reversing camera display: 1. Green guideline: Normal safety line, indicating that the distance between the obstacle and the rear of the vehicle is relatively large, allowing you to reverse with confidence. 2. Yellow guideline indicates a deceleration line: The distance to the rear is 60cm, and you may continue to reverse. However, at the same time, you should reduce the reversing speed and continuously monitor the distance to the obstacle. 3. Red guideline indicates a warning line: The distance to the rear is 30cm, at which point you should stop reversing immediately to avoid colliding with the obstacle behind.

When I first started learning to drive, I didn't understand the trajectory lines very well either. After driving for a few years, I finally got the hang of it. The colored trajectory lines in the rearview camera generally come in two types: one is a fixed reference line, with the red zone indicating the closest safe distance to an obstacle; the other is a steering-responsive line, which bends as you turn the steering wheel, intuitively showing you where the tires will turn. When using them, you need to pay attention to the actual width of the car body—the trajectory lines only represent the predicted path, and there might still be blind spots on either side of the rear. Be extra careful when the camera is blurry in rainy weather, and don't just focus on the screen while ignoring the rearview mirrors. Nowadays, many cars come with automatic braking features, but if the trajectory lines turn red and the alarms go off while reversing, don't force it—it's best to get out and check. Safety first.

I mainly rely on the trajectory lines to adjust my direction while reversing, it's just like the navigation assist in a game. Those curved lines that move with the steering wheel are particularly practical - the more you turn the wheel, the more the line bends, helping you predict the rear wheel's path. The fixed reference lines use colors to indicate distance: green for safe, yellow for caution, and red for very close. In actual operation, you need to combine the trajectory lines with the radar alerts, especially when reversing at night when the rearview mirror visibility is poor - that's when these aids really help with positioning. Be careful not to over-rely on the camera display though, as the lens distortion can compress objects at the edges. After a few practice runs you'll get the hang of it, and remember to angle your rearview mirrors downward to better coordinate with the camera display.

Mastering the trajectory lines of the reversing camera is actually not difficult. When the steering wheel is centered, the straight trajectory line points directly backward. As you turn the steering wheel, the colored curves bend to indicate the steering angle. Among the three main trajectory lines, the middle one represents the endpoint of the reversing path, while the two sides show the tire tracks. I recommend beginners focus on the red warning zone, which corresponds to the distance from the bumper – when the red line appears, there's about half a meter left. Always reverse slowly while observing the real-time changes in the trajectory lines. If the camera has parking assist functionality, following the guidance frames makes operations easier. However, the wide-angle lens may cause visual distortion, so the key is to familiarize yourself with your vehicle's actual dimensions through practice.

The reversing trajectory lines should be used in conjunction with steering wheel movements. When turning the steering wheel to the left, the curve bends left, indicating the direction of the left rear wheel; turning right causes the curve to bend right. When stationary, the trajectory line is straight. Excessive speed may cause the trajectory lines to lag behind the actual position, so it's best to maintain partial clutch engagement and reverse slowly. On rainy or snowy days, trajectory lines often appear offset due to the camera being obstructed or system delays caused by low temperatures. In such cases, rely more on the actual distance sensors. I've noticed many drivers overlook the color coding of the trajectory lines: green means you can continue reversing, yellow indicates the need to slow down, and red means you must stop. Regularly cleaning the camera ensures clear display of the trajectory lines.
