How does the Audi A5's automatic start-stop system work?

I've heard that the Audi A5 has an automatic start-stop system, but I'm not sure how it works. Can someone explain it to me?

The automatic start-stop system in the Audi A5 works by shutting off the engine when the car comes to a complete stop, and restarting it when you release the brake. This helps save fuel and reduce emissions. My personal advice is to turn off the system if you're in heavy stop-and-go traffic, as the constant starting and stopping can wear down the starter.

The start-stop system is controlled by a sensor that detects when the car is at a complete stop, and a switch that activates when you release the brake. It's a great feature for saving fuel, especially in city driving. My tip is to keep your foot on the brake when the engine shuts off to prevent any delay in starting back up.
