How do I turn on auto start-stop in my Audi A4?

I recently purchased an Audi A4 and I noticed that the engine turns off when I come to a stop. How can I turn on the auto start-stop function and does it have any benefits?

To turn on auto start-stop in your Audi A4, press the 'A' button located on the center console. This function helps to save fuel and reduce emissions while you're stuck in traffic or at a red light. However, it might take some getting used to as the engine restarts when you release the brake.

I personally prefer to turn off the auto start-stop function in my Audi A4 as it can be quite jarring when the engine suddenly turns back on. Plus, constantly starting and stopping the engine can actually wear it out faster. But it's entirely up to your personal preference and driving habits.
