SAFETY RESTRAINTS

Personal Safety System™
The Personal Safety System™ provides an improved overall level of
frontal crash protection to front seat occupants and is designed to help
further 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.
• 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 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 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.
