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 classifications and 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 outboard 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 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.
