How do I check the tire pressure on my Audi A7?

I recently purchased a used Audi A7 and want to make sure the tires are properly inflated. Can someone provide instructions on where to find the tire pressure gauge and how to use it?

To check the tire pressure on your Audi A7, locate the tire pressure gauge in the glove compartment. Remove the cap from the valve stem of each tire and press the gauge onto the stem. The gauge will provide a reading of your tire's pressure. Make sure to check all four tires and adjust the pressure accordingly.
