How to reset the Audi A4 tire pressure control system?

I accidentally changed the settings in my Audi A4's tire pressure control system. How can I reset it to the default settings and ensure my tires are properly inflated?

To reset the tire pressure control system on an Audi A4, start the engine and press the menu button on the center console. Use the arrow buttons to navigate to the tire pressure settings and press OK. Then, select 'reset' and confirm. This will reset the system to the factory settings. As a rule of thumb, check your tire pressure at least once a month and adjust accordingly.
