What is the function of 'A' in the car?

[LuciaLee]

The 'A' in the car refers to the Auto Hold function. After turning on this switch, when the vehicle brakes during driving, even if the brake is released, the vehicle will not continue to move. It will only resume driving when the driver presses the accelerator. The features of the Auto Hold function are: 1. It prevents the vehicle from rolling when stopping briefly at traffic lights; 2. When starting on an uphill, the system automatically brakes to prevent rolling back, and releases the wheels to move forward once starting; 3. For parking and locking, there's no need to pull the handbrake as the system automatically brakes the wheels, but this feature is only available in some car models. Steps to use Auto Hold: 1. Press the car's brake pedal; 2. Press the car's one-touch start button; 3. The car's dashboard lights up, and the vehicle's power is fully connected; 4. Press the Auto Hold button inside the car to activate the Auto Hold mode.
