Hi! I have a 92 Civic LX and I noticed today that when I start it the airbag light stays on longer than the other lights and it's making a very obnoxious beeping noise, but then the beeping stops and the light turns off. I can't remember if this has happened before and I don't have an owner's manual. The car is new, to me at least, and I'm just learning to drive a manual transmission, so it gets knocked around and stalls out a lot while I'm practicing. Does anyone know what's wrong and how much it will cost to fix?
