How can I change the tire pressure in an Audi A2?

I recently bought a used Audi A2 and am not sure how to adjust the tire pressure. Can someone provide detailed instructions on how to go about this process?

To change the tire pressure in your Audi A2, start by determining the recommended pressure for your specific vehicle. You can find this information on the inside of your driver side door or in your owner's manual. Once you have the recommended pressure, use a tire pressure gauge to measure the current pressure of your tires. If the pressure is too high, use a tire pressure gauge to release some air. If the pressure is too low, use an air compressor to add air until it reaches the recommended level. Don't forget to check the pressure in all four of your tires.
