How do I activate the auto start/stop function in my Audi A3?

I just got a new Audi A3 and I noticed it has an auto start/stop function. How can I activate it and make sure it's working properly?

To activate the auto start/stop function in your Audi A3, simply press the button with the letter 'A' on it, located next to your gear shift. This will engage the function and it will automatically shut off the engine when you come to a stop, helping to save fuel.

Along with pressing the 'A' button, make sure that your Audi A3 is in the drive mode setting 'D'. If it's in any other mode, the auto start/stop function may not work properly.

In order for the auto start/stop function to work efficiently, make sure to also keep your air conditioning and heating needs to a minimum. This can drain the battery and affect the overall performance of the function.
