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

I've noticed that my new Audi A1 has an automatic start-stop function. How does this technology work and how can I maximize its efficiency?

The automatic start-stop function works by automatically turning off the engine when the car is stationary (e.g. at a red light) and restarting it when you release the brake. This helps to reduce fuel consumption and emissions.

To maximize its efficiency, try to avoid using heavy accessories such as the air conditioner when the start-stop function is active. This can drain the battery and cause the engine to turn back on unnecessarily.

Additionally, keep your foot on the brake when the engine has turned off. This will prevent the engine from restarting if you lift your foot off the brake too quickly.
