A seat belt warning light that does not alert occupants of an unbelted seat belt or an SRS system that deploys improperly can both increase the risk of injury in a crash.

The seat belt system may inaccurately detect that passengers are belted, preventing the seat belt warning light from illuminating and possibly causing the supplemental restraint system to not deploy as intended during a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

What to do: Book this in with a dealer now. It affects a safety system.
