How do I properly check my Audi A6's tire pressure?

I recently purchased a used Audi A6 and want to ensure I am properly maintaining my tires to ensure my safety and car's performance. Can someone provide me with detailed steps on how to accurately check my tire pressure and what the recommended pressure should be for my car?

To accurately check your tire pressure, first make sure your tires are cold and have not been driven recently. Use a reliable tire pressure gauge to take the readings and compare them to the recommended pressure in your owner's manual. If the pressure is too low, use an air compressor to fill them to the correct level. Remember to check the pressure regularly to ensure safe driving and prolong the life of your tires.
