What is the function of Audi A8's automatic start-stop system?

I recently purchased an Audi A8 and noticed that it has an automatic start-stop system. Can anyone explain what this system does and how it benefits the vehicle?

The automatic start-stop system in the Audi A8 helps to reduce fuel consumption and emissions by automatically shutting off the engine when the vehicle is stationary, such as at a stoplight or in traffic. This not only saves on fuel costs, but also has a positive impact on the environment.

The automatic start-stop system is a feature that can help improve fuel efficiency and reduce emissions in the Audi A8. By automatically turning off the engine when the vehicle is idle, it eliminates unnecessary fuel consumption and reduces carbon emissions.

The Audi A8's automatic start-stop system is a helpful tool for those with a busy lifestyle. Not only does it reduce fuel consumption and emissions, but it also helps reduce wear and tear on the engine by minimizing idle time. This can lead to cost savings on maintenance in the long run.
