How to check tire pressure on a Audi A6?

I recently purchased an Audi A6 and need to check the tire pressure. The manual is unclear on the specific steps to take. Can anyone provide a clear and concise guide on how to check the tire pressure on a Audi A6?

First, gather all necessary tools such as a tire pressure gauge and an air compressor. Next, locate the tire pressure information for your Audi A6 which is usually found on the inside of the driver's side door. Then, unscrew the valve cap on one of the tires and place the gauge on the valve stem. Record the pressure reading and compare it to the recommended pressure. If it's low, use the air compressor to fill the tire to the correct pressure. Remember to check all tires and reattach the valve caps.
