What is the best way to maintain the tire pressure in an Audi A3?

I recently got an Audi A3 and I am not sure how to properly maintain the tire pressure. I want to make sure I am doing it correctly to ensure the safety and performance of my car. Can you provide some guidance?

The best way to maintain the tire pressure in your Audi A3 is to check it at least once a month. Use a tire pressure gauge to ensure it is at the recommended level, which can be found in your car manual or inside the driver's door.
