If the airbag light is staying on, you need to take the car to the dealer to
check it out. It likely means your airbag system, or part of it, will not
function in a crash. It could be as simple as a faulty seat belt latch,
which should be covered under warranty (if Toyota has a lifetime seat belt
warranty as does Honda).
I have Camry 2005 and had a similar case. It turned out that there
was a loose pin connector under front passanger seat. I think
somebody moved an object under the seat and pulled out the connector
partially. Fortunatly my car was under warranty at that time and
Toyota dealer fixed the issue for free.
