How do I reset the tire pressure warning light on my Audi A4?

I recently replaced the tires on my Audi A4 and now the tire pressure warning light won't turn off. What steps do I need to take to reset it?

First, locate the reset button on your dashboard. It should be near the steering wheel or in the glove compartment. Press and hold the button until the light flashes three times, then release.

If the reset button doesn't work, try adjusting the tire pressure on all four tires to the recommended level. Then drive your Audi for a few minutes at a speed over 15mph to allow the system to reset itself.
