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 may activate 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 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, like infants

Owners Guide, 1st Printing
USA(fus)
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.
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.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.
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 passenger front airbag and
passenger seat-mounted side airbag when the passenger seat is empty.
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, 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 outboard 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
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, 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.

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.

Energy management retractors
Your vehicle has a safety belt system equipped with energy management
retractors at the driver and front outboard passenger seating positions.
An energy management retractor is a device which pays out webbing in a
controlled manner. This feature is designed to help further reduce the
risk of force-related injuries to the occupant.
Safety belt systems equipped with an energy management retractor must
be replaced if they were in use during a frontal collision which resulted
in deployment of the frontal airbags. Refer to theSafety belt
maintenancesection in this chapter.
The front and rear safety restraints in the vehicle are combination lap
and shoulder belts. The front passenger outboard and rear outboard seat
safety belts have two types of locking modes described below:
Vehicle sensitive mode
The vehicle sensitive mode is the normal retractor mode, allowing 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.
The front outboard safety belts can also be made to lock manually by
quickly pulling on the shoulder belt. Rear safety belts (if equipped) can
also be made to lock up by pulling quickly on the belt.
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, or
the Regular Cab center safety belt.
When to use the automatic locking mode
•Anytimea child safety seat is installed in a front outboard passenger
seating position in a Regular Cab/ SuperCab/ SuperCrew or any rear
seating position of a SuperCab or SuperCrew. The Regular Cab front
center seatbelt has a cinch mechanism. Refer toSafety belt with
cinch tongue (Regular Cab center only)earlier in this chapter.
Children 12 years old and under should be properly restrained in a
rear seat whenever possible. Refer toSafety restraints for children
orSafety seats for childrenlater in this chapter.

WARNING:After any vehicle collision, the safety belt systems
at all seating positions (except the driver position, which does
not have this feature) must be checked by an authorized dealer to
verify that the automatic locking retractor feature for child seats is still
functioning properly. In addition, all safety belts should be checked for
proper 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 when checked by an 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
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 Safety Canopy
system. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the 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.
WARNING:The driver and the right 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 or Safety Canopyand safety belt
pretensioners.
WARNING:Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Refer to theSafety belt maintenancesection in this chapter.

Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety Systemwhich can
then adapt the airbag deployment or safety belt pretensioner activation
based upon safety belt usage.
WARNING:The Personal Safety Systemprovides the most
benefit to belted occupants. The system monitors and tailors the
air bag deployment based upon safety belt usage. Failure to properly
wear your safety belt will increase your risk of injury.
Front safety belt height adjustment
Your vehicle has safety belt height
adjustments at the front outboard
seating positions. Adjust the height
of the shoulder belt so the belt rests
across the middle of your shoulder.
To adjust the shoulder belt height,
pull on the center button and slide
the height adjuster up or down.
Release the button and pull down
on the height adjuster to make sure
it is locked in place.
WARNING:Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the safety
belt and increase the risk of injury in a collision.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

Reasons given... Consider...
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
WARNING:Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minderchime. To
do so may adversely affect the performance of the vehicle’s air bag
system.
Deactivating/activating the Belt-Minderfeature
The driver and front passenger Belt-Minderare
deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.
Read Steps1-4thoroughly before proceeding with the
deactivation/activation programming procedure.
Note:If you are using MyKey™, the Belt-Mindercannot be disabled.
Also, if the Belt-Minderhas been previously disabled, it will be
re-enabled after the use of MyKey™. Refer toMyKey™in theLocks
and securitychapter.
The driver and front passenger Belt-Minderfeatures can be
deactivated/activated by performing the following procedure:
Before following the procedure, make sure that:
•The parking brake is set
•The gearshift is in P (Park)
•The ignition switch is in the off position
•The driver and front passenger safety belts are unbuckled
