Seating and Safety Restraints How does the personal safety system work? The Personal Safety System can adapt the deployment strategy of your vehicle's safety devices according to crash severity and occupant conditions. A collection of crash and occupant sensors provides information to the Restraints Control Module (RCM). During a crash, the RCM activates the safety belt pretensioners and/or either one or both stages of the dualĆstage air bag supplemental restraints based on crash severity and occupant conditions. The fact that the pretensioners or air bags did not activate for both front seat occupants in a collision does not mean that something is wrong with the system. Rather, it means the Personal Safety System determined the accident conditions (crash severity, belt usage, etc.) were not appropriate to activate these safety devices. Front air bags and pretensioners are designed to activate only in frontal and nearĆfrontal collisions, not rollovers, sideĆimpacts, or rearĆimpacts unless the collision causes sufficient longitudinal deceleration. 135
