How do I activate the automatic start-stop function in my Audi A5?

I recently purchased a new Audi A5 and I noticed that the automatic start-stop function is not enabled. I want to know how to activate this feature for better fuel efficiency.

To activate the automatic start-stop function in your Audi A5, you will need to press the Auto button located on the center console. This will enable the feature and it will automatically turn off when the engine reaches a certain temperature, helping to reduce fuel consumption. Make sure to also check your car's manual for more detailed instructions.
