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.
•Restraints Control Module (RCM).
•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
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 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.

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 toAirbag 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 airbags 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 airbag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver airbag by providing a lower airbag output level.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System™ to tailor the airbag deployment
and safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety restraintssection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers when the
vehicle is equipped with the Safety Canopy™ system. This helps increase
the effectiveness of the safety belts. In frontal collisions, the safety belt
pretensioners can be activated alone or, if the collision is of sufficient
severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toSafety restraintssection in
this chapter.

Determining if the Personal Safety System™ is operational
The Personal Safety System™ uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System™ is not
required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following:
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after the ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System™ serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an airbag
supplemental restraint system (SRS) is provided.
