What is the function of Car A?

Car A refers to the Auto Hold function. Below is a detailed introduction about the Auto Hold function: 1. Function of Auto Hold: The Auto Hold function, also known as AUTOHOLD and abbreviated as A, is represented by a button icon in the car that shows two parentheses () with a circle in the middle containing a capital letter A. The purpose of Auto Hold is to allow the vehicle to automatically apply the brakes based on actual conditions without requiring driver intervention. 2. How the Auto Hold system works: The brake management system controls the braking of all four wheels through an extension of the Electronic Parking Brake (EPB) function. In other words, the Auto Hold system is an extension of the EPB and is controlled by the ESP (Electronic Stability Program) component. When the vehicle is temporarily stopped and needs to restart within a short period, the parking function is handled by the ESP-controlled brakes.
After years of driving, I've found that the 'A' function on cars usually refers to the automatic control system, especially for air conditioning. After starting the vehicle, pressing the button labeled 'AUTO' allows the system to automatically adjust based on the actual temperature inside the car and your settings. For example, in summer when it's hot inside, it will increase the cooling; in winter when it's cold, it will automatically provide heating. The fan speed is also program-controlled, but you can still manually adjust the knob for fine-tuning. Some models offer additional circulation mode settings via the central control screen, such as internal circulation to prevent outside dust from entering, or external circulation to bring in fresh air, which is very helpful for air quality. When using it, I recommend avoiding frequent switching to prevent additional power consumption or wear and tear on components. Automatic headlights follow a similar concept, turning on automatically in low light to enhance nighttime driving safety.
