How do I reset my airbag light on a 2010 Chevy cobalt?

To reset the airbag light on a 2010 Chevy Cobalt, first ensure that there are no issues with the airbag system by checking for any diagnostic trouble codes using an OBD-II scanner. If there are no codes, disconnect the vehicle's battery for about 10 minutes to reset the system. Reconnect the battery and start the car; the airbag light should turn off if there are no underlying problems. If the light remains on, it's best to consult a professional mechanic to diagnose the issue.
