How the Air Bag Supplemental Restraint System Operates The driver air bag is in the center of the steering wheel. The front passenger seat air bag is located in the center of the instrument panel ledge above the glove compartment. Both air bags are designed to stay out of sight until they are activated. The location of air bags and warning labels If a collision occurs, the sensors sense the severity of the impact and activate the air bags if necessary. The air bag system is designed to deploy in frontal and front-angled collisions more severe than hitting a parked vehicle (of similar size and weight) head-on at about 28 mph (45 km/h). Because the system senses the crash severity rather than vehicle speed, some frontal collisions at speeds above 28 mph (45 km/h) will not inflate the air bag. When the sensors activate the system, the air bags inflate rapidly, filling with non-toxic nitrogen gas in a fraction of a second. Immediately after inflation, the air bags deflate by releasing the nitrogen gas through vent holes. The whole process takes place in a matter of seconds. 20
