WARNING:

Accidental air bag deployment is possible. Personal injury may result. Avoid area near steering wheel and instrument panel even if air bags have deployed. Dual-stage air bag modules may be present that could contain an undeployed stage. When disposing of a deployed dual-stage air bag, always treat it as a live module. See appropriate Air Bag Service & Repair article in Mitchell’s Repair Center TechAdvisor product for more information.
