How do I check the tire pressure on my Audi A8?

I just purchased an Audi A8 and want to make sure I am properly maintaining it. What is the correct way to check the tire pressure on my car? Do I need any special tools or is there a specific procedure I should follow?

To check your tire pressure on your Audi A8, you will need a tire pressure gauge. You can find these at any auto parts store or even at most gas stations. Simply unscrew the valve cap on your tire, place the gauge over the valve, and press down until the gauge reaches the recommended tire pressure. Make sure to check all four tires.
