How do I manually check my Audi A3's tire pressure?

I have been having some issues with my tires and want to make sure I am maintaining them properly. Can someone provide step by step instructions on manually checking the tire pressure in an Audi A3?

To manually check the tire pressure of your Audi A3, start by locating the tire pressure monitoring system reset button. Then, unscrew the valve cap on each tire and use a tire pressure gauge to check the pressure. Remember to check all four tires, including the spare, and compare the readings to the manufacturer's recommended pressure. If any tire is low, use an air pump to fill it to the appropriate pressure. Finally, press and hold the reset button until the TPMS warning light turns off.
