How do I check the tire pressure in my Audi A5?

I just bought a used Audi A5 and I want to make sure my tires are properly inflated. Can you walk me through the steps to check and adjust the tire pressure?

Checking the tire pressure in your Audi A5 is a fairly straightforward process. First, locate the tire pressure information sticker on the driver's side door jamb. This will give you the recommended tire pressure for your vehicle. Next, remove the valve stem caps from each tire. Use a tire pressure gauge to measure the pressure in each tire, making sure to place the gauge firmly on the valve stem. If the pressure is too low, use a tire inflator to add air until it reaches the recommended pressure. If the pressure is too high, use a tire pressure gauge to release air until it reaches the recommended level.
