Abstract
A system for warning when the liquid level of a air bag gas source as dropped to a predetermined level, such that the gas source would not be adequate to properly inflate the bag upon actuation. The source is mounted to rotate with a steering wheel. An electrically conductive float floats in the liquid such that it always remains at the upper portion of the source. The float comes into contact with contacts in the gas source, when the liquid level drops to the predetermined level, to complete an electric circuit to a signaling device and/or a drive disabling device.
