How does the Personal Safety System姞 work?

The Personal Safety System威 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 may activate the safety belt pretensioners and/or either one or both

stages of the dual-stage airbag supplemental restraints based on crash

severity and occupant conditions.

The fact that the pretensioners or airbags 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威 determined

the accident conditions (crash severity, belt usage, etc.) were not

appropriate to activate these safety devices. Front airbags are designed

to activate only in frontal and near-frontal collisions, not rollovers,

side-impacts, or rear-impacts unless the collision causes sufficient

longitudinal deceleration.

Driver and passenger dual-stage airbag supplemental restraints

The dual-stage airbags offer the capability to tailor the level of airbag

inflation energy. A lower, less forceful energy level is provided for more

common, moderate-severity impacts. A higher energy level is used for

the most severe impacts. Refer to Airbag supplemental restraints

(SRS) section in this chapter.

Front crash severity sensor

The front crash severity sensor enhances the ability to detect the

severity of an impact. Positioned up front, it provides valuable

information early in the crash event on the severity of the impact. This
