What does the A next to the electronic handbrake mean?

It refers to the Auto-Hold system, a technological application that enables automatic parking brake functionality while the vehicle is in operation. This technology allows drivers to avoid prolonged braking when the vehicle comes to a stop, and prevents unnecessary rolling when the automatic electronic parking brake is engaged. Relevant details are as follows: 1. The Auto-Hold system's functionality is not simply achieved by using the electronic parking brake. When stopping on slopes or at traffic lights, drivers typically use the handbrake for parking. Relying solely on the electronic parking brake in such scenarios would result in slower response times. 2. Manually operating a handbrake takes no more than 0.3 seconds, and human control offers more flexibility than electronic control. Engaging the electronic parking brake requires a preliminary brake pedal action and button response time (to prevent accidental activation), with the motor operation itself taking about 0.5 seconds. Even when the electronic parking brake automatically releases during throttle application, the action can feel somewhat abrupt. Therefore, the Auto-Hold system operates on a different principle.
I guess you noticed that A button while driving, I also encountered it when I recently changed cars. As a new car owner, I was quite curious at first and had to ask the salesperson to figure out it's the Auto Hold function. When activated, after you stop the car—like at a red light or on a slope—the system automatically holds the brake for you, so you don’t have to keep pressing the pedal. Tried using it in traffic jams, and it’s a lifesaver—just lift your foot and the car stays put, then hit the gas when the light turns green without any hassle. Especially reassuring on slopes to prevent rolling back, feels like having a thoughtful co-pilot in the city. Of course, remember to turn it off before washing or towing the car to avoid accidents. As a new driver, I highly recommend trying it—convenient and safe.
