The ESP in a car is automatically engaged and requires no manual operation. The main sensors of the ESP system and their functions are as follows: 1. Steering angle sensor. Monitors the rotation angle of the steering wheel to help determine whether the car is moving in the correct direction. 2. Wheel speed sensor. Monitors the speed of each wheel to determine if any wheel is slipping. 3. Yaw rate sensor. Records the movement of the car around its vertical axis to determine if the car is skidding. 4. Lateral acceleration sensor. Detects the centrifugal force generated when the car turns to determine if the car is slipping while navigating a curve.

When I'm driving, ESP is like my invisible partner, always protecting me from losing control. Before starting the vehicle, I glance at the dashboard to make sure the ESP warning light isn't on, indicating the system is functioning normally. While driving, I never worry about manually turning it on or off—it's enabled by default. Only on slippery roads or during high-speed skids does ESP automatically intervene, helping me correct direction by braking specific wheels. The only time I might press the button is during off-road driving or if an experienced driver wants to disable it for drifting practice, but 99% of the time I keep it active—it gives me peace of mind. I also advise beginners to develop a habit: regularly check ESP functionality through brake tests or garage diagnostics to prevent malfunctions. ESP is hassle-free and highly effective; the key is not to tamper with the button unnecessarily.

As a driving instructor, I always tell my students that ESP's real value shines in critical moments. The system activates automatically when the vehicle starts, and all you need to do is drive normally—don't even think about pressing any buttons to turn it off. When the car skids during sharp turns or on rainy days, ESP instantly detects tire slippage and adjusts brake force distribution to pull the vehicle back on track. I often take students to open areas for simulated tests, letting them experience the smooth, reassuring safety of ESP intervention. For daily use, I recommend keeping ESP enabled, especially on icy roads or when towing, as it helps prevent accidents. During routine maintenance, have the ESP system checked to avoid performance issues. Simply put, ESP is like an electronic bodyguard—you don't need to control it manually, just drive with confidence.

Having worked in an auto repair shop for years, I've noticed many car owners don't know how to use ESP properly. Simply put, ESP is enabled by default—it starts monitoring wheel speeds as soon as you start the car. While driving, the system operates continuously in the background without requiring any button presses. Some vehicles have an ESP switch, but unless you're drifting or racing on a track, don't turn it off. The key is to ensure the ESP warning light doesn't stay illuminated; otherwise, check for sensor, pump, or wiring issues. For regular maintenance, I recommend checking ESP response during brake tests to keep the system healthy. Don't overthink manual control—ESP is an automatic anti-skid tool designed to enhance safety. The best way to use it is to avoid unnecessary adjustments and maintain normal driving conditions.
