The P button on the car is for the electronic parking brake. When pressed, the (P) indicator on the dashboard lights up in red, indicating that the parking brake is engaged. The red color of the parking brake display signifies that the parking brake, commonly known as the handbrake, is active. The handbrake provides resistance to the car when parked, preventing it from rolling away. Generally, parking brakes can be divided into mechanical and electronic types. The main difference between them is that the adjustment method changes to an electronic button. Mechanical handbrakes occupy some space inside the car, while electronic handbrakes save space. The principle of both electronic and mechanical handbrakes is essentially the same, relying on the friction between the brake disc and brake pads for adjustment. Electronic handbrakes, also known as electronic parking brake systems, integrate the temporary braking function during driving with the long-term braking function after parking, achieving parking braking through electronic adjustment. The basic parking function of electronic handbrakes has been expanded to include automatic parking and automatic hold features. The application of AUTOHOLD automatic parking technology allows drivers to avoid prolonged braking when parked. When the automatic electronic parking brake is activated, it prevents the car from sliding unnecessarily. Mechanical handbrakes use traditional methods, employing mechanical cables to achieve parking braking. They are not electrically adjusted and have fewer electronic components, offering advantages such as stability, reliability, low cost, and low failure rates. Additionally, on different road surfaces, the braking force can be adjusted manually, providing better control, making mechanical handbrakes essential for drift enthusiasts. Their biggest drawback is that they occupy more space and are less aesthetically pleasing. Other button functions in the car are as follows: Fuel tank release button: This button is used to remotely open the fuel tank cap from inside the car. Vehicles equipped with this button allow the driver to open the fuel tank cap from inside the car. ESP switch: This is used to turn the vehicle's ESP system on or off. The ESP system is set to the working state by default. Reverse radar button: This allows the driver to manually turn the vehicle's reverse radar system on or off as needed. Central lock button: This is the control button for the vehicle's central door lock system. The driver can press this button to simultaneously lock or unlock all the car doors. Air conditioning buttons: During summer and winter, when temperatures are extreme, drivers and passengers often use the air conditioning for comfort. However, incorrect operation of the air conditioning buttons can affect their effectiveness. Wiper button: Wipers are commonly used during rainy weather and when the windshield is dirty.
