JEEP LIBERTY 2008 KK / 2.G Repair Manual

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
ªPAD Indicator Lightº 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 being
measured 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 seatbecause 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 ªAirbag Warning
Lightº (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 ªAirbag Warning Lightº is turned
on whenever there is a fault that can affect the operation
of the airbag system. If there is a fault present in the OCS,
both the ªPAD Indicator Lightº and the ªAirbag Warning
Lightº 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 ªPAD Indicator Lightº and the ªAirbag Warning
Light.º Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the
passenger 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 passenger 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 is about half of the time that it takes
to blink your eyes. The bags then quickly deflate while
helping to restrain the driver and front passenger. Thedriver's front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger's 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.²TheOccupant 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-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
²Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.

²TheSide Impact SRS Side Curtain Airbagsare de-
signed to activate only in certain side collisions and
rollover events. When the ORC detects a collision
requiring the side curtain airbag to inflate, it signals
the inflators on the crash side of the vehicle or both
sides of the vehicle for a rollover event. A quantity of
nontoxic gas is generated to inflate the side curtain
airbag. The inflating side curtain airbag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time that it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the side curtain
airbag inflates. This especially applies to children. The
side curtain airbag is only about 3
1¤2inches (9 cm) thick
when it is inflated.The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components or
assembly.
The following requirements must be strictly adhered to:
²Do not modify the front passenger seat assembly or
components in any way.
²At 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 or its related com-
ponents may inadvertently change the airbag deploy-
ment 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 accident. 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 Controller (ORC) detects a moderate-
to-severe collision, to help restrain the driver and front
passenger, and then to immediately deflate.NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision, which deploys the airbags, any
or all of the following may occur:
²The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
However, if you haven't healed significantly within a
few days, or if you have any blistering, see your doctor
immediately.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²As the airbags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer's instruc-
tions for cleaning.
²It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
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 Sys-
tem serviced as well.
Enhanced Accident Response System
In the event of an impact that causes airbag deployment,
with the vehicle stopped, and the vehicle communication
network intact, and the power intact, the Enhanced
Accident Response System performs the following func-
tions:
²Cuts off fuel to the engine.
²Flashes hazard lights.

²Turns on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
²Unlocks the doors automatically.
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!
²Modifications 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 passenger side of the instrument panel. Do not modify the front
bumper or vehicle body structure.
²Do not attempt to modify any part of your advanced airbag system. The
airbag may inflate accidentally or may not function properly if modifica-
tions 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 disabili-
ties, contact your authorized dealer.
²Do not place or hang any items such as add-on video players on the front
passenger seat back. The additional weight may cause the Occupant
Classification System to be unable to classify the front seat passenger
correctly. This could allow the passenger frontal airbag to inflate when it
is not desired.
²It 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:
²The Airbag Warning Light does not come on or flickers
during the 6 to 8 seconds when the ignition switch is
first turned on.
²The light remains on or flickers after the 6 to 8 second
interval.
²The light flickers or comes on and remains on while
driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5-seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, or near deployment,
and up to a quarter second of high-speed deceleration
data during and/or after air bag deployment or near-
deployment. EDR data are ONLY recorded if an airbag
deploys, or nearly deploys, and are otherwise unavail-
able.
NOTE:
²A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
²Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).

In conjunction with other data gathered during a com-
plete 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 beprovided 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,
provided confidentiality of personal data is thereafter
preserved
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product
3. Requested by police under a legal warrant
4. Otherwise required by law

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time Ð 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.

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.
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:
Infants and Child Restraints
²
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 ªconvertibleº child seats.
²The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). ªConvertibleº child seats can be
used either rearward-facing or forward-facing in the
vehicle. 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
