AC System JEEP LIBERTY 2007 KJ / 1.G Owner's Manual

WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC maymodify the rate of inflation based on the occupant size
provided by the Occupant Classification Module. The
ORC will not detect roll over, or rear impacts.
The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
Also, the ORC turns on the AIRBAG warning light
(located in the instrument cluster) and PAD indicator
light (located in the front passenger grab handle) for 6 to
8 seconds for a self-check when the ignition is first turned
on. After the self-check, the AIRBAG warning light will
turn off. The PAD indicator light will function normally
(Refer to “Passenger Airbag Disable (PAD) Indicator
Light” in this section). If the ORC detects a malfunction
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

in any part of the system, it turns on the AIRBAG
warning light either momentarily or continuously. A
single chime will sound if the light comes on again after
initial start up.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•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 toinflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant 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
is about 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’s front airbag gas is vented through vent
holes in the sides of the airbag. The passenger’s front
airbag gas is vented through vent holes in the sides of
the airbag. In this way the airbags do not interfere with
your control of the vehicle.•TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions. When the ORC
(with side impact option) detects a collision requiring
the window bags to inflate, it signals the inflators on

the crash side of the vehicle. A quantity of nontoxic gas
is generated to inflate the window bag. The inflating
window bag 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 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
window bag inflates. This especially applies to chil-
dren. The window bag is only about 3
12inches (9 cm)
thick when it is inflated.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
•TheOccupant Classification System (OCS)will clas-
sify an occupant in the front passenger seat into a size
category based on sensor readings from within the
seat cushion. Occupants should try to remain in anormally seated position. If the occupant’s weight is
transferred to another object in the vehicle (i.e. feet on
the dashboard), the OCS may not be able to properly
approximate occupant size. Furthermore, the occupant
size may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat. If there is
a rapid change in temperature or humidity, the OCS
may not be able to properly approximate occupant
size. If your seat including your trim cover and
cushion needs to be serviced in any way, take the
vehicle to your authorized dealer. Only manufacturer
approved seat accessories may be used.
If there is a fault present in the system, the AIRBAG
warning light will light indicating that you should
take the vehicle to an authorized dealer. In the pres-
ence of an occupant in the passenger seat, if both the
PAD indicator light (located in the front passenger
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

should always use the PAD indicator light as an indica-
tion if the front passenger is properly positioned or not. If
the PAD indicator light comes on when an adult is in the
passenger seat, have the passenger re-position them-
selves in the seat until the light goes out. Remember, if
the PAD indicator light is illuminated the passenger front
airbag will not inflate. For most children properly seated
on the front seat and most properly installed child
restraint systems, the airbag will be disabled and the PAD
indicator light will be on. However, under certain condi-
tions even with the child restraint system has been
installed properly, the PAD indicator light may not be on
even though the air bag is disabled. This can occur if the
child restraint is lighter than the threshold weight neces-
sary to turn the PAD indicator light on. If this happens to
you, you can check to ensure the airbag is disabled by
performing the following simple procedure. Place the
ignition key in the RUN position and apply downward
pressure to the child restraint on the surface that the childwill be sitting on. Slowly count to 10 and watch the PAD
indicator light. The PAD indicator light should turn on.
When you release the pressure, the PAD indicator light
may stay on or may turn off but the airbag is disabled. If
at all possible, place children 12 years and younger in a
back seat.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into one of three size categories
based on the input from the Bladder Assembly and a
Belt Tension Sensor. The size categories include empty,
child, and adult. The OCM sends the Occupant Clas-
sification to the ORC to determine if a front passenger
airbag is allowed. If a fault is present, the AIRBAG
warning light is illuminated.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•ThePassenger Airbag Disabled (PAD) Indicator
Lightindicates to the driver and passenger when the
airbag is turned OFF. In the presence of a properly
seated occupant, when the PAD indicator light is
illuminated, the airbag is OFF. Also, when the Occu-
pant Classification System detects either an empty seat
or a weight less than the predetermined threshold, the
ORC will not illuminate the PAD indicator light even
though the airbag is turned OFF.
•TheBelt Tension Sensor (BTS)is located at the
outboard passenger lap belt anchor. The BTS creates a
signal based on outboard lap belt tension. This signal
is sent to the OCM to ensure that the resultant bladder
pressure increase due to applied lap belt tension does
not cause a small occupant to be classified as a larger
occupant.
•TheBladder Mat and Pressure Sensorare located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
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,
assembly, or to the seat cover.

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).
The following requirements must be strictly adhered to:
•Do not modify the front passenger seat assembly or
components in any way.
•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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the impact sensors detect a moderate-to-severe
frontal collision, to help restrain the driver and front
passenger, and then immediately deflate.
NOTE:A frontal 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:
•The 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. As 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 manufac-
turer’s instructions for cleaning.•It 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 pretensioners, and the front passenger seat
belt retractor assembly, replaced by an authorized
dealer as soon as possible. Also, have the Occupant
Classification System serviced as well.
Enhanced Accident Response System (E.A.R.S.)
If the airbags deploy after an impact and the electrical
system remains functional, the interior lights will turn on
and the power door locks (if equipped) will unlock 5
seconds after airbag deployment.Also, the fuel system will shut off immediately upon
airbag deployment (gasoline models only). The ignition
switch will need to be cycled (i.e. turn the ignition key
from the ON position to the LOCK position) after ap-
proximately 5 seconds in order to restart the vehicle.

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, vehicle body structure, or
add aftermarket side steps or running boards.
•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 ad-
vanced airbag system service. If your seat including your
trim cover and cushion needs to be serviced in any way,
take the vehicle to your authorized dealer. Only manu-
facturer approved seat accessories may be used. If it is
necessary to modify an advanced airbag system for
persons with disabilities, contact your authorized dealer.
WARNING!
•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.
