How to Use the Car ESC?

Car ESC is generally a function that is enabled by default. It automatically activates during steering or sharp turns, primarily to make the car more stable and safe when changing lanes or navigating curves. More information about the ESC system is as follows: 1. Prerequisites for ESC system activation: Under normal driving conditions, the ESC system does not function. When the ignition switch is turned on, the ESC is enabled, the warning light illuminates, and when the ESC is turned off, the indicator light comes on and extinguishes after about 4 seconds. 2. Function of the ESC system: The ESC mainly controls the longitudinal and lateral stability of the vehicle to ensure stable driving. For example, when the car oversteers during a left turn on slippery roads (such as when the tail swings to the right or the sensors detect too abrupt a turn), it quickly brakes the right front wheel to restore traction, generating an opposite torque to keep the car in its original lane.
I've been driving for over twenty years and know how important it is to understand the ESC system. ESC stands for Electronic Stability Control, and it automatically activates when the vehicle starts—no manual operation is needed. There’s usually a button labeled ESC or with a car skidding icon near the center console; pressing it turns the system off, but it resets to "on" the next time you start the car. Normally, you should keep it enabled while driving. When taking sharp turns, driving on slippery roads, or making emergency maneuvers, the system helps stabilize your direction by braking individual wheels without requiring any intervention from you. Remember, never turn it off unnecessarily—unless in specific situations like being stuck in deep snow where you need to wiggle the wheels to get free, in which case you can briefly disable it and immediately turn it back on. I find this feature especially useful in rain or snow, as it helps prevent many accidents. Make it a habit to check that the button’s indicator light is off (indicating the system is on) to ensure safe driving.
When I was repairing the car, I learned about how ESC works, and using it is very simple: once the engine is started, ESC is on by default. The button is usually located below the steering wheel or next to the gear shift, and pressing it once toggles the status light on or off. It's recommended to keep it on most of the time; the system works silently while driving, and when you sharply turn the steering wheel or the wheels detect slippage, it automatically adjusts the braking force to regain control. There are no extra steps required from you; on the safety front, it significantly reduces the risk of skidding. Only in professional scenarios like off-roading or testing should you consider turning it off briefly, but make sure to turn it back on immediately afterward to ensure the safety of your family and friends during daily driving.
I find ESC incredibly convenient: the system automatically activates when the car starts, and while there might be a button on the center console to toggle it, it's recommended to always keep it on. You don't need to do anything while driving; the system discreetly applies brakes to individual wheels when taking sharp turns or on slippery roads to help stabilize the car. Keeping it on is highly effective in preventing accidents, especially during rainy or snowy conditions. Only in special situations, like being stuck in mud, should you temporarily turn it off to get unstuck, and remember to turn it back on immediately afterward. Understanding this allows you to drive with more peace of mind and less stress.
