How do I adjust the tire pressure in my Audi A4?

I just purchased a new Audi A4 and I want to make sure my tires have the correct tire pressure. Can you provide me with the step-by-step process for adjusting the tire pressure in my car?

To adjust the tire pressure in your Audi A4, first, locate the tire pressure information on the driver's side door jamb. Then, using a tire pressure gauge, check the current pressure in your tires and compare it to the recommended pressure listed on the door jamb. Use an air compressor if needed to add or release air until your tires are at the correct pressure.
