How can I check the tire pressure on my Audi A6?

I am not sure how to check the tire pressure on my Audi A6. Can someone explain the process to me in detail?

To check the tire pressure on your Audi A6, first locate the tire pressure label on the driver's side door frame. Then, using a tire pressure gauge, unscrew the valve stem cap on each tire and firmly press the gauge onto the valve stem. The gauge will provide a reading of the tire pressure. If the pressure is too low, use an air compressor to fill the tires to the recommended pressure. If the pressure is too high, use a tire pressure gauge to release air until it reaches the recommended pressure.

Another way to check your Audi A6's tire pressure is by using the tire pressure monitoring system. This system will display the current tire pressure for each individual tire on your dashboard. To access this information, press the 'Menu' button on your dashboard and navigate to the 'Tire Pressure' option. Make sure to check the pressure when the tires are cold, and adjust as needed.
