What does the 'A' on a car mean?

[Bentley]

The 'A' on a car refers to the vehicle's Auto Hold function. Vehicles equipped with an electronic parking brake typically come with the Auto Hold feature, which is not enabled by default and requires the driver to manually activate it. Once the Auto Hold function is activated, it eliminates the need for frequent operation of the handbrake or electronic parking brake. For automatic transmission models, it also reduces the need to frequently switch between D to N or D to P. When the vehicle brakes during driving and comes to a complete stop, even if the brake pedal is released, the vehicle will not necessarily continue moving. It will only proceed forward when the accelerator pedal is pressed again. The English name for Auto Hold is AUTOHOLD, and this button is usually located next to the electronic parking brake.
