How does the start-stop system work in an Audi A4?

I've recently purchased an Audi A4 and I've noticed that it has a start-stop system. How does this feature work and does it have any impact on the car's performance?

The start-stop system in an Audi A4 is designed to automatically turn off the engine when the car is idling or stopped, and start it again when the driver presses the accelerator. This helps to reduce fuel consumption and lower emissions. You can turn off this feature if you prefer.

The start-stop system has sensors that monitor the engine, battery, and temperature to ensure it only shuts off and restarts the engine when necessary. It may take some getting used to, but it does not affect the overall performance of the car.
