How do I enable the automatic start-stop feature in my Audi A1?

I have a new Audi A1 and I heard it has an automatic start-stop feature that improves fuel efficiency. How do I turn it on?

To enable the automatic start-stop feature in your Audi A1, simply press the button with the 'A' symbol located near the gear shift. This will activate the feature, which will automatically turn off the engine when you come to a complete stop and start it again when you release the brake.
