Parking sensors emit warning sounds indicating the vehicle is very close to an object. The parking camera displays three colored guide lines: green, yellow, and red. The green line indicates a safe distance of over two meters. The yellow line indicates a distance between 0.7 to 1 meter. The red line indicates 30cm, at which point you must stop.

As a novice driver who just learned how to drive, I also rely on the parking sensors when reversing. It's quite simple: when you shift into reverse gear, the sensors activate and emit audible beeps and flashing warnings when obstacles are detected behind the vehicle. The beeping sound is a "beep-beep" tone that becomes higher-pitched and faster as the distance decreases, resembling an accelerating heartbeat to warn you of imminent collision. Sometimes a small icon or indicator light appears on the rearview mirror - green indicates a safe distance, yellow means caution is needed, and red requires immediate stopping. I don't just rely on the sound; I also like to lean out of the window to check the actual situation, because the sensors only cover about one meter behind the car and might miss small children or thin poles. During practice sessions, I find an empty parking lot to reverse slowly and get accustomed to this warning rhythm. Remember, parking sensors are just an assistive tool - novice drivers should always reverse at low speed and avoid rushing to accelerate. Once you develop the habit, reversing becomes much more stable.

I'm quite a car enthusiast and have driven many vehicles, finding that reverse parking sensors are extremely helpful for beginners. The radar system relies on sensors at the rear of the car to detect obstacles, with different models having varying alert methods: some use beeping sounds where higher frequency indicates closer proximity to obstacles; others come with a display screen showing colors or lines to indicate distance, such as red zones signaling danger. I recommend that beginners first familiarize themselves with their car's radar settings, as sensitivity and volume can usually be adjusted in the settings menu. When reversing, it's safer to use the rearview mirror and rear camera in conjunction with the sensors rather than relying solely on audio alerts. A common issue is sensors getting covered in mud or dirt during rainy weather, leading to false alarms or malfunctions, so regular cleaning of the rear end is advised. Practicing in narrow alleys or underground mall parking lots is most beneficial, as the abundance of obstacles helps sharpen judgment skills. While radar is smart, it shouldn't be fully trusted—after all, it may react slower to sudden situations like a dog running past.

As someone who prioritizes driving safety, I believe novice drivers should be extra cautious when using parking sensors. Don't panic immediately when the alarm sounds - first distinguish whether it's continuous beeping or intermittent alerts: the former may indicate close proximity to obstacles requiring a full stop, while the latter serves as a distant warning allowing for steering adjustments. Always physically turn to check rear windows and side mirrors to compensate for sensor blind spots. I've seen accidents happen when people over-relied on sensors and missed approaching pedestrians or small pets. It's wise to test sensor functionality after starting the vehicle - simply block a sensor with your hand to verify alarm activation. Keep reversing speed below 5km/h and distribute your attention between auditory alerts, display monitoring, and environmental observation. If sensors malfunction (e.g., due to a blown fuse), remain calm, use the handbrake to stop, and perform basic troubleshooting. Remember - safety comes first. Parking sensors are merely tools that should never replace your own judgment.
