The U shape is supposed to look like a cross section slice of your tire.
The indicator lamp is telling you that one or more of your tires is underinflated.
Check them all when the tires are cool and add air to the recommended pressure (I think that is 32 pounds on the 09 Civic).
This a great safety feature. Underinflated tires make the car handle poorly and could cause an accident.
