What does the 'A' on a car represent?

[DelKarter]

The 'A' on a car represents the Auto Hold system. When this switch is activated, even if the vehicle is brought to a stop during driving, it will remain in the braking state and will not continue moving. The vehicle will only proceed when the accelerator is pressed again. Auto Hold refers to an automatic braking function. Once enabled, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake. The working principle of Auto Hold: The vehicle's ECU computer uses sensors installed on the car to detect the body's level and wheel torque, determining whether braking is necessary to prevent rolling. The braking force applied to the wheels is not excessive, just enough to stop the vehicle from moving, ensuring that when the accelerator is pressed again, there is no severe jerking forward.
