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

I have a new Audi A1 and was wondering how to enable the automatic start-stop feature in the car. It doesn't seem to be activated by default.

To activate the automatic start-stop feature on your Audi A1, start by pressing the 'AUTO' button on the climate control panel.

Once the 'AUTO' button is pressed, the engine will automatically switch off when the car comes to a complete stop and the clutch pedal is released. Simply press the clutch pedal again to restart the engine.

It's worth noting that the automatic start-stop feature can also be deactivated by pressing the 'AUTO' button again or by putting the gear stick in the 'P' (park) position.
