Your vehicle’s Personal Safety System

௢ consists of:

• Driver and passenger dual-stage airbag supplemental restraints.
• Front safety belts with pretensioners, energy management retractors,

and safety belt usage sensors.

• Driver’s seat position sensor.
• Front crash severity sensor.
• Front passenger sensing system
• “Passenger airbag off” or “pass airbag off” indicator lamp
• 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 conditions. A
collection of crash sensors provides information to the Restraints Control
Module (RCM). During a crash, the RCM activates the safety belt
pretensioners and/or either none, one, or both stages of the dual-stage
airbag supplemental restraints based on crash severity 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
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
