How to Use a Parking Sensor?

The method to use a parking sensor is: 1. When the parking sensor emits an alarm sound, it indicates that the vehicle is very close to an object, and you should always pay attention to stopping; 2. The parking camera has three auxiliary lines: green, yellow, and red. The green line indicates a safe distance of more than two meters, allowing you to reverse with confidence. The yellow line indicates a distance between 0.7 to 1 meter, requiring caution when accelerating or braking. The red line indicates a distance of 30cm, and you must stop immediately. A parking sensor is a safety assistance device for parking or reversing, which informs the driver of surrounding obstacles through sound or a more intuitive display. It eliminates the troubles caused by the driver's need to check all around when parking, reversing, or starting the vehicle, and helps the driver overcome blind spots and unclear vision.
The reverse radar, those little sensors on the rear bumper, detects obstacles when you're backing up and beeps to warn you. The key is listening to the sound pattern: slow, spaced beeps mean the obstacle is still far away; as the beeps get faster and more frequent, you're getting closer; if it's a continuous beep, you're practically touching it - stop immediately. With 20+ years of city driving, I use it most in crowded parking lots, always checking mirrors first while listening to the alerts, never relying solely on it since low curbs or thin poles might escape detection. This gadget has saved me countless fender-benders, but I still recommend backing up slowly while scanning surroundings - safety first.
As a new driver, the parking sensors have been a huge help. At first, the beeping sounds made me nervous, but I gradually learned the patterns: a single beep with pauses means objects are about 3 meters away; frequent beeping indicates around 1 meter; and continuous rapid beeping warns of less than half a meter—almost a collision. The screen shows a color-changing progress bar, with green for far and red for close. I always remind myself to stay calm while reversing, using the sound changes to assist judgment, but never neglecting to glance back—small animals might go undetected. Developing safe driving habits early is key; I always check my surroundings before parking.
The reverse radar is very practical. It uses sound waves to detect objects behind you. When reversing, just listen to the sound rhythm: long intervals indicate a safe distance; short and frequent beeps mean caution is needed; if it keeps screaming, stop immediately. Pairing it with the display screen for bar-shaped indicators makes it more accurate. Don’t rely on it entirely—stay alert yourself.
