How does the Personal Safety Systemwork?
The Personal Safety Systemcan 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 Systemdetermined
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 Systemto 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 Systemto
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 Systemto 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 Canopysystem. This maximizes 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 Systemis operational
The Personal Safety Systemuses 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 Systemis 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 Systemserviced 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.
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.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.

Seating and Safety Restraints
169

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.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
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.
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
with the exception of a 60/40 front split bench seat center lap belt.
First row center lap belt (if equipped)
Adjusting the lap belt
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
The lap belt does not adjust automatically.
Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle. To tighten the
belt, pull the loose end of the belt
through the tongue until it fits
snugly across the hips.

Shorten and fasten the belt when
not in use.
All of the passenger combination lap and shoulder belts have two 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.
Automatic locking mode
In this mode, the shoulder belt is 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.
When to use the automatic locking mode
•Anytimea child safety seat (except a booster) is installed in the
vehicle. 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
1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and
pull downward until the entire belt
is pulled out.
3. 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 return to the
vehicle sensitive (emergency) locking mode.
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 seat belt system function.

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 removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and optional Safety
Canopysystem. When the safety belt pretensioner deploys, the lap and
shoulder belt are tightened.
When the optional Safety Canopysystem 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.
The driver and the right front passenger seat 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 or Safety Canopyand safety belt
pretensioners.
Refer to theSafety belt maintenancesection in this chapter.
