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 activates 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 and
pretensioners 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 passenger sensing system
For airbags 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 airbag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the airbag. For other occupants, this occurs when the
occupant is not properly restrained by safety 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 front passenger sensing system can automatically turn off the
passenger front airbag when a rear facing child seat, a forward-facing
child restraint, or a booster seat is detected. Even with this technology,
parents areSTRONGLYencouraged to always properly restrain children
in the rear seat. The sensor also turns off the airbag when the passenger
seat is empty to prevent unnecessary replacement of the airbag(s) after
a collision.
When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal airbag, the “pass airbag off” indicator
will light and stay lit to remind you that the front passenger frontal
airbag is off. SeeFront passenger sensing systemin theAirbag
supplemental restraint system (SRS)section of this chapter.
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 belt usage sensorslater in this chapter.

Front outboard 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. 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 outboard safety belt energy management retractors
The front 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 toEnergy management retractorssection 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, front
passenger sensing system, 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 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.

BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly “automatic locking retractor” feature or
any other safety belt function is not operating properly when checked
authorized dealer.
Failure to replace the Belt and Retractor assembly could
increase the risk of injury in collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front airbag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. Refer to theSafety belt maintenance
section in this chapter.
The driver and front passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the
vehicle is involved in a collision that results in deployment of front
airbags and safety belt pretensioners.
Front safety belt height adjustment
Your vehicle has safety belt height adjustments for the driver and front
outboard passenger. Adjust the height of the shoulder belt so the belt
rests across the middle of your shoulder.

AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The airbag supplemental restraint system is designed to work in
conjunction with the safety belts to help protect the driver and front
outboard passenger from certain upper body injuries. The term
“supplemental restraint” means the airbags are intended as a supplement
to the safety belts. Airbags alone cannot protect as well as airbags plus
safety belts in impacts for which the airbags are designed to deploy, and
airbags do not offer any protection in crashes for which they do not
deploy.
The airbag supplemental restraint system consists of:
•driver and passenger dual stage airbag modules (which include the
inflators and airbags).
•one or more impact and safing sensors.
•the same indicator light, RCM (restraints control module) and
diagnostic unit used for the Personal safety system.
•Front passenger sensing system
•Passenger airbag off indicator light.
The airbag supplemental restraints are an integral part of the Personal
Safety System. They are designed to be deployed in cases where the
Personal Safety System has determined the occupant conditions and
crash severity are appropriate to activate these devices. Refer to the
Personal Safety Systemsection in this chapter.
Important supplemental restraint system (SRS) precautions
The supplemental restraint system is designed to work with the safety
belt to help protect the driver and right front passenger from certain
upper body injuries.
Airbags DO NOT inflate slowly or gently and the risk of injury from a
deploying airbag is greatest close to the trim covering the airbag module.

The front passenger airbag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.
Additional equipment may affect the performance of the airbag
sensors increasing the risk of injury. Please refer to theBody
Builders Layout Bookfor instructions about the appropriate
installation of additional equipment.
Children and airbags
For additional important safety information, read all information on
safety restraints in this guide.
Do not install a child seat in
a center facing jump seat.
Airbags can kill or injure a child in a child seat.NEVERplace a
rear-facing child seat in front of an active airbag. If you must use
a forward-facing child seat in the front seat, move the seat all the way
back.
Booster seats must be installed only in seating positions
equipped with a combination lap/shoulder belt.
To reduce the risk of injury, make sure children sit where they
can be properly restrained.

If the airbag has deployed,the airbag will not function again
and must be replaced immediately.If the airbag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster or a tone to
indicate the condition of the system. Refer toAirbag readinessin the
Instrument Clusterchapter. Routine maintenance of the airbag is not
required.
A difficulty with the system is indicated by one or more of the following:
•The readiness lights will either
flash or stay lit.
•The readiness lights will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Disposal of airbags and airbag equipped vehicles
(including pretensioners)
See your authorized dealer. Airbags MUST BE disposed of by qualified
personnel.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s frontal air bag is not
part of the front passenger sensing system. The front passenger sensing
system works with sensors that are part of the front passenger’s seat and
safety belt. The sensors are designed to detect the presence of a
properly seated occupant and determine if the front passenger’s frontal
air bag should be enabled (may inflate) or not.
