What does the 'A' button next to the electronic handbrake mean?

Electronic handbrake next to the A button is the automatic parking system. After turning on this switch, when the vehicle is braked to a stop during driving, even if the brake is released, the vehicle will not continue to move. It will only resume driving when the accelerator is pressed. If you want to turn it off, you have to manually switch it off. The automatic parking system is a technical application that can achieve automatic handbrake function while the car is running. This technology allows drivers to avoid prolonged braking when the vehicle stops, and prevents unnecessary sliding when the automatic electronic parking brake is activated. The working principle of the automatic parking system lies in the brake management system's control of the four-wheel brakes through the extended function of the electronic handbrake.
I remember when I first started learning to drive, I was also very curious about the big 'A' button next to the electronic handbrake—it's the auto-hold function, which is really thoughtfully designed. It automatically maintains the braking state when you stop, so you don't have to keep pressing the foot brake. For example, at red lights or in traffic jams, after stopping the car and activating it, you can easily release your feet. When ready to go, a light press on the accelerator automatically releases it, allowing the car to move smoothly. This system combines the electronic braking unit to lock the wheels, preventing the risk of rolling back on slopes. I find it especially safe to use in rainy or snowy weather, reducing slip-related accidents. After using it for a few years, it has made long-distance driving less tiring and is particularly suitable for beginners in urban areas with frequent stops.
Having driven many cars, I found that the A button next to the electronic parking brake is the auto-hold system, which simply means it helps you brake automatically. When the car comes to a complete stop, activating it locks the brakes, so you don't need to keep pressing the pedal. When starting again, a little throttle will release it. This function originates from the electronic control unit integrating sensor signals to execute. I use it most often at traffic lights or during highway congestion—it's worry-free, labor-saving, and energy-efficient, preventing accidental slips caused by missteps. It's advisable to check the vehicle manual to confirm applicability; generally, modern cars come with this automatic assist.
