What does a circle with an 'A' inside mean on a car?

A circle with an 'A' inside on a car is the hill start assist switch. When pressed, it allows you to start on a slope by simply accelerating without rolling back. Below is an introduction to the electronic parking brake: 1. Working Principle: The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both achieving parking control through the friction generated between the brake disc and brake pads, except that the control method has changed from the mechanical handbrake lever to an electronic button. 2. Functions of the Electronic Parking Brake: (1) The parking brake handle inside the cabin is eliminated, providing more design space for the overall interior styling. (2) The parking brake is replaced by a single button, making it simple and effortless, reducing the operational intensity for drivers, especially female drivers.
When I drive my car, that symbol with an 'A' in a circle always appears, meaning the auto start-stop function is activated. It automatically shuts off the engine at red lights or temporary stops to save fuel, then quickly restarts the engine when you release the brake or press the accelerator. This thing really saves a lot of money, especially when driving in the city—it can reduce fuel consumption by half a liter a day. I've tried turning it off manually; there's a button in the car that deactivates it with one press, which is more comfortable during heavy snow or when using the AC in hot weather. But be aware that the symbol turns yellow if the battery is old, so regular battery maintenance is needed. This feature has no major issues, being both eco-friendly and cost-saving.
