How do I change my Audi A1's tire pressure?

I recently noticed that my Audi A1's tire pressure is lower than recommended. How can I adjust it to the correct level?

To change your Audi A1's tire pressure, first make sure your car is parked in a safe and level location. Then, locate the tire pressure label on the driver's side door jamb or in the vehicle's manual. Use a tire pressure gauge to check each tire and adjust with a tire inflator as needed. Don't forget to recheck the pressure after a few minutes to ensure it is at the correct level.
