reduce the risk of airbag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.

Your vehicle’s Personal Safety System consists of:
• Driver and passenger dual-stage airbag supplemental restraints with

driver knee airbag.

• Front outboard safety belts with pretensioners, energy management

retractors (first row only), and safety belt usage sensors.

• Driver’s seat position sensor.
• Front passenger sensing system
• “Passenger airbag off” or “pass airbag off” indicator lamp
• Front crash severity sensor.
• 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, front passenger sensing system, 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
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 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. The pretensioners are designed to activate in
frontal and near-frontal collisions, and in side collisions.

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
