How does the Personal Safety Systemwork?
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 may activate 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
(SRS)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, 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.
WARNING: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.
WARNING: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 front
passenger airbag and passenger seat-mounted side airbag. The system is
designed to help protect small (child size) occupants from frontal airbag
deployments when they are seated or restrained in the front passenger
seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents areSTRONGLY
encouraged to always properly restrain children in the rear seat. The
sensor also turns off the passenger front airbag and passenger
seat-mounted side airbag when the passenger seat is empty.
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.

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. 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 toEnergy management feature
section in this chapter.
Determining if the Personal Safety Systemis 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 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, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.

Safety restraints precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
in a rear seating position where they can be properly restrained.
WARNING: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.
WARNING: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.
WARNING:It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle that is not equipped
with seats and safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety
belt.
WARNING:Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one
tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.

WARNING:Safety belts and seats can become hot in a vehicle
that has been closed up in sunny weather; they could burn a
small child. Check seat covers and buckles before you place a child
anywhere near them.
WARNING:Front and rear seat occupants, including pregnant
women, should wear safety belts for optimum protection in an
accident.
Energy management feature
•This vehicle has a safety belt system with an energy management
feature at the front seating positions to help further reduce the risk of
injury in the event of a head-on collision.
•This safety belt system has a retractor assembly that is designed to
extend the safety belt webbing in a controlled manner. This helps
reduce the belt force acting on the user’s chest.
WARNING: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 by an authorized dealer. Failure to replace the
Belt and Retractor assembly could increase the risk of injury in
collisions.
Combination lap and shoulder belts
1. Insert the belt tongue into the proper buckle (the buckle closest to
the direction the tongue is coming from) until you hear a snap and feel it
latch. Make sure the tongue is securely fastened in the buckle.

•Front and rear seats
2. To unfasten, push the release button and remove the tongue from the
buckle.
•Front and rear seats
All safety restraints in the vehicle are combination lap and shoulder
belts. All of the passenger combination lap and shoulder belts have three
types of locking modes described below:
Vehicle sensitive mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 5 mph
(8 km/h) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
Webbing extraction sensitive mode
The webbing sensitive locking mode locks the webbing and prevents
more belt from being pulled out if the belt is pulled out too quickly. The
belt will unlock when you stop pulling on it.

Automatic locking mode
When to use the automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
This mode should be usedany timea child safety seat, except a
booster, is installed in passenger front or rear seating positions. Children
12 years old and under should be properly restrained in the rear seat
whenever possible. Refer toSafety restraints for childrenorSafety
seats for childrenlater in this chapter.
How to use the automatic locking mode
•Buckle the combination lap and
shoulder belt.
•Grasp the shoulder portion and
pull downward until the entire
belt is pulled out.
•Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Unbuckle the combination lap and shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive mode.

WARNING:After any vehicle collision, the combination lap and
shoulder belt system at all passenger seating positions must be
checked by an authorized dealer to verify that the “automatic locking
retractor” feature for child seats is still functioning properly, in addition
to other checks for proper safety belt system function.
WARNING: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. In addition, all safety belts should be checked for proper
function. 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
right front passenger seating positions.
The safety belt pretensioner tightens the safety belts firmly against the
occupant’s body at the start of the crash.
When the Safety Canopy
system, seat-mounted side airbags, and/or the
front airbags are activated, the safety belt pretensioners for the driver
and right front passenger seating positions will be activated when the
respective seatbelt is properly buckled.
WARNING: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, seat-mounted side airbags and Safety
Canopy
, and safety belt pretensioners.
