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. The pretensioners are designed to activate in
frontal and near-frontal collisions, and in side collisions and rollovers.
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.

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- front outboardsection 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, driver seat
position sensor, and front passenger sensing system. 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-Minder
The Belt-Minderfeature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
light in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.
The Belt-Minderfeature uses information from the front passenger
sensing system to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
Belt-Minderfeature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the front passenger sensing system

The following are reasons most often given for not wearing safety belts
(All statistics based on U.S. data):
Reasons given... Consider...
“Crashes are rare
events”36700 crashes occur every day.The more
we drive, the more we are exposed to “rare”
events, even for good drivers.1in4ofus
will be seriously injured in a crash during
our lifetime.
“I’m not going far”3of4fatal crashes occur within25miles
(40 km) of home.
“Belts are
uncomfortable”We design our safety belts to enhance
comfort. If you are uncomfortable - try
different positions for the safety belt upper
anchorage and seatback which should be as
upright as possible; this can improve comfort.
“I was in a hurry”Prime time for an accident.Belt-Minder
reminds us to take a few seconds to buckle
up.
“Safety belts don’t
work”Safety belts,when used properly,reduce
risk of deathto front seat occupants by
45% in cars,and by60% in light trucks.
“Traffic is light”Nearly 1 of 2 deaths occur in
single-vehicle crashes,many when no other
vehicles are around.
“Belts wrinkle my
clothes”Possibly, but a serious crash can do much
more than wrinkle your clothes, particularly if
you are unbelted.
“The people I’m with
don’t wear belts”Set the example, teen deaths occur 4 times
more often in vehicles with TWO or MORE
people. Children and younger brothers/sisters
imitate behavior they see.
“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 areejected
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 airbag
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 Steps1-5thoroughly before proceeding with the
deactivation/activation programming procedure.
Note: The driver and front passenger Belt-Minderfeatures must be
disabled/enabled separately. Both cannot be disable/enabled during the
same key cycle.
Note:If you are using MyKey™, the Belt-Mindercannot be disabled.
Also, if the Belt-Minderhas been previously disabled, it will be
re-enabled during 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
WARNING:While the design allows you to deactivate your
Belt-Minder, this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Mindersystem activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minderfeature while driving the vehicle.
1. Turn the ignition switch to the on position. DO NOT START THE
ENGINE.
2. Wait until the safety belt warning light turns off (Approximately one
minute).

3. Wait 10 seconds after the safety belt warning light turns off.
•Step 4 must be completed within 20 seconds after the completion of
Step 3.
4. For the seating position being disabled buckle then unbuckle the
safety belt three times at a moderate speed, ending in the unbuckled
state.
•After Step 4, the safety belt warning light will be turned on for three
seconds.
5. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds.
•This will enable the Belt-Minderfeature for that seating position if it
is currently disabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds, followed by three
seconds with the light off, then followed by the safety belt warning
light flashing four times per second for three seconds again.
AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The airbag supplemental restraint system (SRS) 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 offer the most protection when used with
safety belts for crash conditions for which airbags are designed to deploy.
Airbags do not offer any protection in crashes for which they do not
deploy.
Seating and Safety Restraints

To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly one or two degrees from the upright position.
WARNING:Do not put anything on or over the air bag module.
Placing objects on or over the air bag inflation area may cause
those objects to be propelled by the air bag into your face and torso
causing serious injury.
WARNING:Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses. See your
authorized dealer.
WARNING: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.
Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
WARNING: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.

WARNING:If the air bag has deployed,the air bag will not
function again and must be replaced immediately.If the air
bag is not replaced, the unrepaired area will increase the risk of injury
in a collision.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags).
•side airbags and Safety Canopy. Refer toSeat-mounted side airbag
systemandSafety Canopysystemlater in this chapter.
•one or more impact and safing sensors.
•driver and front passenger safety belt pretensioner
•a readiness light and tone.
•diagnostic module.
•the electrical wiring which connects the components.
•Front passenger sensing system. Refer toFront passenger sensing
systemlater in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
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 airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,

•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions,
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,
•the system determines that a small child is present in a booster seat,
•a front passenger takes his/her weight off of the seat for a period of
time,
•a child or a small person occupies the front passenger seat.
When the passenger airbag off light is illuminated, the passenger side
airbag may be disabled to avoid the risk of airbag deployment injuries.
The front passenger sensing system
uses apassenger airbag offor
pass airbag offindicator which will
illuminate and stay lit to remind you
that the front passenger frontal airbag is disabled. The indicator lamp is
located in the center of the instrument panel above the radio.
Note:The indicator lamp will illuminate for a short period of time when
the ignition is turned to the on position to confirm it is functional.
When the front passenger seat is not occupied (empty seat) or in the
event that the front passenger frontal airbag is enabled (may inflate), the
indicator lamp will be unlit.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when a rear facing infant
seat, a forward-facing child restraint, or a booster seat is detected.
•When the front passenger sensing system disables (will not inflate)
the front passenger frontal airbag, the indicator lamp will illuminate
and stay lit to remind you that the front passenger frontal airbag is
disabled.
•If the child restraint has been installed and the indicator lamp is not
lit, then turn the vehicle off, remove the child restraint from the
vehicle and reinstall the restraint following the child restraint
manufacturer’s instructions.
The front passenger sensing system is designed to enable (may inflate)
the front passenger’s frontal airbag anytime the system senses that a
person of adult size is sitting properly in the front passenger seat.
•When the front passenger sensing system enables the front passenger
frontal airbag (may inflate), the indicator will be unlit and stay unlit.
