Airbag Readiness Light
The system checks the airbag's electrical system for possible malfunctions. If the light stays on it indicates there is an electrical problem. The system check includes the airbag sensor(s), passenger sensing system, the pretensioners, the airbag modules, the wiring, and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System .

The airbag readiness light comes on solid for a few seconds when the engine is started. If the light does not come on then, have it fixed immediately.
WARNING
If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inflate in a crash, or they could even inflate without a crash. To help avoid injury, have the vehicle serviced right away.
If there is a problem with the airbag system, a Driver Information Center (DIC) message can also come on. See Airbag System Messages for more information.
