What is the function of the car off?

Car off means turning off the vehicle stability control system. The following is a detailed introduction to the vehicle stability system: 1. Function: By analyzing the vehicle driving state information transmitted by various sensors and issuing instructions to ABS, EBD, etc., it can help the vehicle maintain dynamic balance. It can keep the vehicle in the best stability under various conditions, and the effect is more significant in the case of oversteering or understeering. 2. Oversteering situation: When the vehicle stability system sensor detects and transmits the signal to the vehicle electronic stability control unit, it will intervene in the braking of the outer front wheel. After braking on a single side and single wheel, the vehicle can be kept stable without the driver's intervention. 3. Understeering situation: After the vehicle stability system control unit learns through the sensor signal, it brakes the inner rear wheel of the turn. After such braking correction, the vehicle body is also guaranteed to be stable.
I've only been driving for a few years, and the salesperson emphasized that 'off' button when I bought the car. It's located either near the steering wheel or on the center console—just press it to shut off the engine directly. This feature is especially handy for cars with push-button start, eliminating the need to pull out a key like in older models. The operation is super simple—I usually shift to P first and then press 'off' when parking, and the car shuts down quietly. It also prevents accidents, like when parked on a slope, as the parking brake automatically engages after turning off. Remember, in summer, when turning off the AC, the system prompts to save settings, which automatically restore on the next start. After using it a few times, it becomes second nature—saving time and hassle. I'd feel inconvenienced without it now. I recommend new drivers get familiar with the button's location and develop proper on/off habits.
After working in the repair shop for a long time, I've seen too many cases of OFF function failures. Simply put, the OFF button acts like a switch that controls the disconnection of the vehicle's power or engine shutdown. If it malfunctions, the car may fail to turn off, wasting fuel, or even draining the battery. Common issues include poor button contact or aging wiring, causing no response when pressed. For DIY inspection, first check if the button is dusty—cleaning the contacts might solve it; for more complex cases, test if the relay is burnt out. I recommend car owners check the button's responsiveness monthly. If the dashboard remains lit after pressing OFF, immediate repair is needed. Always operate gently to avoid damaging internal spring components.
As a long-time advocate for traffic safety, the off function may seem inconspicuous but can be life-saving in critical moments. For instance, in sudden emergencies, quickly pressing the off button can immediately stop the vehicle to prevent loss of control. The principle involves cutting off the ignition signal to shut down the engine. In daily use, the off function can reduce battery load and minimize fire risks. When operating, ensure the vehicle is stationary to avoid dangers from accidental pressing at high speeds. Practice in simulated environments to develop quick response habits. From an environmental perspective, it also benefits by reducing idle emissions. Never overlook small features—they're as crucial as the brakes.
