How does the automatic stop-start system work in the Audi A1?

I am confused about how the automatic stop-start system in the Audi A1 functions, can someone explain it to me?

The automatic stop-start system in the Audi A1 relies on a battery sensor to determine when to shut off the engine. It also takes into account factors such as engine temperature and cabin temperature to ensure maximum efficiency without compromising driver comfort.

The automatic stop-start system in the Audi A1 is designed to save fuel and reduce emissions. When you come to a stop, the engine will automatically shut off and then restart when you release the brake pedal. This helps to reduce unnecessary idling and improve overall efficiency.
