What does the car button A mean?

Car button A is the automatic parking function switch. The automatic parking function refers to a function that allows the driver to avoid unnecessary vehicle sliding without the need for prolonged braking or activating the electronic parking brake. Introduction to the automatic parking function: The automatic parking function is an extension of the ESP function and is controlled by ESP components. The automatic parking function provides precise parking force through a slope sensor controlled by the controller. When starting the car, the parking control unit calculates information provided by sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly. This significantly reduces the time wasted on judgment based on experience. Automatic parking function: In situations requiring short stops, such as at traffic lights, the system automatically brakes the wheels after the vehicle comes to a complete stop to prevent rolling. During uphill starts, the system automatically brakes to prevent backward sliding. After starting, the system releases the wheels automatically for forward movement. When parking and locking the car, there is no need to pull the handbrake. The system automatically brakes the wheels, but this feature is only available in certain models.
When I see button A in the car, it's usually the AUTO button for automatic climate control. After starting the car, pressing it once will automatically adjust the system to a comfortable state based on the cabin temperature, eliminating the need to manually turn the fan on/off or adjust the temperature. This is especially convenient during winter or summer when entering/exiting the vehicle. I've used this feature many times and find it quite intelligent—for example, after setting 22°C, the computer will automatically adjust fan speed and air recirculation based on sensors. If the AC responds slowly, it might be due to dirty sensors or system lag—try restarting the car. Also remember to regularly clean the AC filter to prevent bacterial growth that could affect performance, which is particularly important for family passengers. In summary, the AUTO button simplifies driving burdens, allowing you to focus more on road safety.
