The seat belt light is a separate issue, but also important. It likely means a seatbelt isn't properly fastened, a sensor is malfunctioning, or there's a problem with the seatbelt system itself.
Here's what you should do:
* Do not drive the car until the INFL REST light is resolved. Your airbags may not deploy in a crash.
* Get the car professionally diagnosed. Take it to a qualified mechanic, preferably one experienced with older Corvettes, or a dealership. The problem could be something simple (like a faulty sensor) or more complex (like a problem with the airbag module itself). They'll use a diagnostic scanner to pinpoint the cause.
* Address the seatbelt light. While less critical than the airbag light, a malfunctioning seatbelt system should also be addressed. The mechanic can likely diagnose this problem at the same time.
Possible causes for the INFL REST light:
* Faulty sensor: Several sensors monitor the airbag system. A malfunctioning sensor will trigger the light.
* Low battery voltage: A weak battery can sometimes cause this light to illuminate.
* Faulty airbag module: This is a more serious issue and likely requires replacement.
* Wiring issues: Damaged or loose wiring in the system can also trigger the light.
Ignoring the INFL REST light is extremely risky. The safety of yourself and your passengers depends on a functioning airbag system. Get it checked out as soon as possible.
