How can I activate the start-stop system in the Audi A1?

I recently bought an Audi A1 and noticed that I can't seem to find the start-stop system button. Can someone guide me on how to activate it?

To activate the start-stop system in your Audi A1, press the 'start-stop' button located next to the gearshift. This will enable the system to automatically switch off your engine when you come to a complete stop. Make sure to release the brake pedal for it to activate.

You can also activate the start-stop system by going into your car's infotainment system and selecting 'Drive Select'. From there, navigate to 'Efficiency' mode and the system will be automatically activated.
