2004 JEEP LIBERTY Owners Manual

You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.
3. The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to inflate.
4. If your vehicle has window bags, do not lean against
the door or window, airbags will inflate forcefully into
the space between you and the door.WARNING!
²Relying 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.
²Being 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.
²If 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
²
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 may
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

modify 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 and
PAD indicator light in the instrument panel 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 ªPassenger Airbag Disable (PAD) Indicator
Lightº in this section). If the ORC detects a malfunction
in any part of the system, it turns on the AIRBAGwarning 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.
²TheOccupant Classification System (OCS)will clas-
sify an occupant into a size category based on sensor
readings from within the seat cushion. Occupants
should try to remain in a normally seated position. If
the occupant's weight is transferred to another object
in the vehicle (i.e. feet on the dashboard), the OCS may
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51

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 in-
cluding your trim cover and cushion needs to be
serviced in any way, take the vehicle to your autho-
rized dealer. Only manufacturer approved seat acces-
sories 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 and AIRBAG warning light are
illuminated the airbag will be disabled.The ORC will not allow front airbag deployment in the
event of a collision for occupants classified into the
empty or child size categories. The PAD indicator light
will illuminate indicating that the Passenger Airbag is
OFF when the OCS has determined that the occupant size
category is a child. Also, when the seat is empty or an
object that weighs less than a predetermined threshold is
placed on the seat, the light will remain OFF. (The PAD
indicator light is an amber light located on the grab
handle in front of the passenger seat.)
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

For almost all sizes of properly seated adults, the passen-
ger frontal airbag will be enabled in the event of a
collision. For small teenagers and some small adults,
depending on size, the airbag may or may not be enabled
in the event of a collision. For small teenagers and some
small adults, depending on size, the airbag may or may
not be enabled in the event of a collision. Both driversand passengers should always use the PAD indicator
light as an indication 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 passen-
ger re-position themselves in the seat until the light goes
out. Remember, if the PAD indicator light is illuminated
the passenger front airbag will not inflate. For properly
installed child restraint systems and children properly
seated on the front passenger seat, the airbag will be
disabled. If at all possible, place children 12 years and
younger in a back seat.²TheDriver 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
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.
²TheOccupant 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.
²ThePassenger 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.
²TheBelt 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
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

pressure increase due to applied lap belt tension does
not cause a small occupant to be classified as a larger
occupant.
²TheBladder Mat and Pressure Sensorare located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
²TheSide 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 thewindow bag inflates. This especially applies to chil-
dren. The window bag is only about 3
1¤2inches (9 cm)
thick when it is inflated.
²TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
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:

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. 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.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 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 10
seconds after airbag deployment.
