How to properly check tire pressure on an Audi A1?

I just got a new Audi A1 and I want to make sure I am checking my tire pressure correctly. Can someone explain the proper steps and tools needed?

First, make sure you have a reliable tire pressure gauge. Then, consult your Audi A1 owner's manual for the recommended tire pressure for your specific vehicle. Once you have that, unscrew the valve cap on each tire and place the gauge firmly over the valve stem. The gauge should provide a reading in PSI. Compare this to the recommended pressure and add or release air as needed.
