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 air bag-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 air bag supplemental restraints.
•Front safety belts with pretensioners, energy management retractors
(first row only), and safety belt usage sensors.
•Driver’s seat position sensor.
•Passenger occupant classification sensor
•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 air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, passenger occupant classification 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
conditions. A collection of crash and occupant sensors provides
information to the Restraints Control Module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag 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 air bags 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 and rollovers
when the vehicle is equipped with the Safety Canopysystem.

Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
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 toAir bag 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
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 air bags and safety belt pretensioners.
Driver’s seat position sensor
The driver’s seat position sensor allows your Personal Safety System to
tailor the deployment level of the driver dual-stage air bag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver air bag by providing a lower air bag output level.
Front passenger sensing system
For air bags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the air bag when it begins to inflate. For some occupants, this occurs
because they are initially sitting very close to the air bag. For other
occupants, this occurs when the occupant is not properly restrained by
seat belts or child safety seats and they move forward during pre-crash
braking. The most effective way to reduce the risk of unnecessary
injuries is to make sure all occupants are properly restrained. Accident
statistics suggest that children are much safer when properly restrained
in the rear seating positions than in the front.
Air bags can kill or injure a child in a child seat.NEVERplace a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The passenger occupant classification sensor can automatically turn off
the passenger front air bag. The system is designed to help protect small
