The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the
“PAD Indicator Light”is not illuminated when an adult
is riding in the front passenger seat. If an adult occu-
pant’s weight is transferred to another part of the vehicle
(like the door or instrument panel), the weight sensors in
the seat may not properly classify the occupant. Objects
lodged under the seat or between the seat and the center
console can prevent the occupant’s weight from beingmeasured properly and may result in the occupant being
improperly classified. Ensure that the front passenger
seat back does not touch anything placed on the back seat
because this can also affect occupant classification. Also,
if you fold down the rear seat check to be sure it doesn’t
touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the“Airbag Warning
Light”(a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The“Airbag Warning Light”is turned
on whenever there is fault that can affect the operation of
the airbag system. If there is a fault present in the OCS,
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
both the“PAD Indicator Light”and the“Airbag Warning
Light”are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is
lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the“PAD Indicator Light”and the“Airbag Warning
Light.”Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50–70 milliseconds. This isabout half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
trol (ORC) Module. The ORC uses the occupant cat-
egory to determine whether the front passenger airbag
should be turned off. It also determines the rate of
airbag inflation during a collision.

•Do not modify the front seat center console or center
position seat in any way.
•Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
•Do not replace the seat cover with an aftermarket seat
cover.
•Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
•At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopar.
WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front
seat passenger if the vehicle is involved in an acci-
dent. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Standards
(FMVSS).
If A Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) Module detects a
moderate-to-severe frontal collision, to help restrain the
driver and front passenger, and then to immediately
deflate.

WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible. Also, have the Occupant Classification
System serviced as well.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could cause it to fail
when you need it. You could be injured if the airbag system is not
there to protect you. Do not modify the components or wiring,
including adding any kind of badges or stickers to the steering wheel
hub trim cover or the upper right side of the instrument panel. Do not
modify the front bumper or vehicle body structure.
•Do not attempt to modify any part of your advanced airbag system.
The airbag may inflate accidentally or may not function properly if
modifications are made. Take your vehicle to an authorized dealer for
any advanced airbag system service. If your seat including your trim
cover and cushion needs to be serviced in any way (including removal
or loosening/tightening of seat attachment bolts), take the vehicle to
your authorized dealer. Only manufacturer approved seat accessories
may be used. If it is necessary to modify an advanced airbag system
for persons with disabilities, contact your authorized dealer.
•Do not place or hang any items such as add-on video players on the
right front passenger seat back. The additional weight may cause the
Occupant Classification System to be unable to correctly classify the
right front occupant. This could allow the passenger frontal airbag to
inflate when it is not desired.
•You need proper knee impact protection in a collision. Do not mount
or locate any aftermarket equipment on or behind the knee bolsters.
•It is dangerous to try to repair any part of the airbag system yourself. Be
sure to tell anyone who works on your vehicle that it has an airbag system.

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see the following list) in the event data
recorder prior to the moment of airbag deployment.
Please note that such data are ONLY recorded if an airbag
deploys, and are otherwise unavailable. In conjunctionwith other data gathered during a complete accident
investigation, the electronic data may be used by
DaimlerChrysler Corporation and others to learn more
about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be

provided to the custodial entity upon request. General
data that does not identify particular vehicles or crashes
may be released for incorporation in aggregate crash
databases, such as those maintained by the US govern-
ment and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidential
data will not be disclosed by DaimlerChrysler Corpora-
tion to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time—babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner’s Manual to ensure you have the right seat
for your child. Use the restraint that is correct for your
child:WARNING!
In a collision, an unrestrained child, even a tiny
baby, can become a missile inside the vehicle. The
force required to hold even an infant on your lap can
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
Infants and Child Restraints
•
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year oldandweigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and“convertible”child seats.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg).“Convertible”child seats often
have a higher weight limit in the rearward-facing
direction than infant carriers do, so they can be used
rearward-facing by children who weigh more than 20
lbs (9 kg) but are less than one year old. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system (Refer to LATCH—Child Seat Anchorage
System in this section.)
•Rearward-facing child seats mustNEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.
WARNING!
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
