The correct way to use the off button in a car is to press and hold this button. The off button is the shutdown key for the vehicle stability control system, which is generally turned on by default. The vehicle stability control system is an active safety system that includes ABS and ASR, preventing the wheels from locking during braking and slipping during startup. The vehicle stability control system can significantly improve the safety coefficient of vehicle handling and driving convenience. Its working principle: when the car is turning, if the front wheels first reach the adhesion limit, it will cause a "drift out" phenomenon. At this time, no matter how the driver turns the steering wheel, the turning radius cannot be reduced, making it difficult to follow the track, resulting in steering failure, known as understeer.
As a regular commuter who drives frequently, I find the proper use of the OFF button in the car quite straightforward. It's mainly used for systems like the air conditioning: when cooling or heating isn't needed, pressing the OFF button directly shuts off the compressor, which can save a significant amount of fuel, especially during low-speed city driving or in cool weather. Sometimes I also use it for the radio—if I'm tired of listening or need to focus on driving, a quick press to turn it off helps avoid distractions. The key is to develop the habit of promptly turning off unnecessary devices to protect battery life—I once neglected this and ended up with difficulty starting the car. Additionally, before parking for an extended period, it's best to check that all devices are in the OFF state to prevent draining the battery. In short, though operating the OFF button is a small action, daily use can help make the car more durable and fuel-efficient.
