How do I properly check my Audi A2's tire pressure?

I recently got my Audi A2 and I'm not sure how to check the tire pressure. Can you walk me through the process step by step?

First, make sure your car is on a flat, level surface. Then, locate the tire pressure gauge and remove the cap from the tire valve. Press the gauge firmly onto the valve and take note of the reading. If the reading is lower than the manufacturer's recommended pressure, use an air compressor to fill the tire to the correct pressure. If the reading is higher, you can release some air using the gauge or a small tool. Repeat for all tires and don't forget to put the cap back on the valve when you're done.

It's important to check your tire pressure regularly to ensure optimal performance and safety. Begin by checking the manufacturer's recommended pressure, which can usually be found on a sticker inside the driver's side door. Then, follow the same steps as before to check and adjust the pressure as needed. Don't forget to also check the spare tire pressure, which is often overlooked.
