How do I reset the tire pressure warning in my Audi A5?

I recently noticed that the tire pressure warning light is on in my Audi A5. How do I go about resetting it myself without having to take it to the dealership?

To reset the tire pressure warning in your Audi A5, first make sure all of your tires are properly inflated. Then, press the reset button located under the steering wheel. If the light does not turn off, you may need to have the sensors reprogrammed by a mechanic.
