• Passenger Airbag Off indicator light.

• Restraints Control Module (RCM) with impact and safing sensors.

• Restraint system warning light and back-up tone.

• The electrical wiring for the airbags, crash sensor(s), safety belt

pretensioners, front safety belt usage sensors, driver seat position

sensor, and indicator lights.

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

classification and 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

none, one, or both stages of the dual-stage airbag supplemental restraints

based on crash severity and occupant classification and 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 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

allows your Personal Safety System to distinguish between different

levels of crash severity and modify the deployment strategy of the

dual-stage airbags and safety belt pretensioners.
