What does 'off' mean when it appears on a car?

When 'off' appears on a car, it refers to the vehicle stability control system, also known as the anti-skid control system. This is an active safety system in automobiles that enhances the vehicle's handling safety coefficient and driving convenience. The illumination of 'off' indicates that the vehicle's stability control system is either turned off or malfunctioning. The characteristics of the vehicle stability control system include: 1. Real-time monitoring of the driver's control actions; 2. Active regulation of the engine throttle and speed, adjustment of wheel driving force and braking force, and correction of the vehicle's oversteer and understeer; 3. When the driver operates improperly or the road conditions are abnormal, the system will alert the driver with a warning light.
I've been driving for over twenty years and often see the OFF light come on, usually indicating that the auto start-stop system is turned off. This system automatically shuts off the engine when stopped to save fuel, but if you find it annoying and press the central control button to turn it off, the OFF light will illuminate as a reminder. Driving normally isn't a problem, just with slightly higher fuel consumption; one time I ignored the light, and my fuel consumption increased by nearly one liter per 100 kilometers. If the light comes on for no apparent reason, like the ESP OFF light on slippery roads, it means the anti-skid function is disabled, making the wheels prone to skidding, which is very dangerous. I must immediately pull over to check if the button was accidentally pressed. If that's not the issue, I'll take it to a repair shop to check for computer faults—never delay when it comes to driving safety.
As a safety-conscious person, when I see the OFF light in my car, it usually means the traction control system is deactivated. This feature normally helps prevent wheel slippage, and turning it off can make the vehicle prone to losing control on slopes or wet roads. Last month, I accidentally turned off the ESP OFF light and had a scary moment when the car slid during a turn. Now, whenever I see the light on, I first check if I didn't manually deactivate it. If not, it might be due to a blown fuse or a system error affecting control. I recommend driving at reduced speed, avoiding sudden braking, and stopping at a roadside shop to check the error codes with a diagnostic tool before continuing.
