2005 JEEP LIBERTY warning

WARNING!
•Do not put anything on or around the front airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured be-
cause the airbags are not there to protect you. These
protective covers for the airbag cushions are de-
signed to open only when the airbags are inflating.
•If your vehicle is equipped with window bags, do
not stack luggage or other cargo up high enough
to block the location of the window bag. The area
where the window bag is located should remain
free from any obstructions.
•If your vehicle is equipped with window bags, do
not have any accessory items installed which will
alter the roof, including adding a sunroof to your
vehicle. Do not add roof racks that require perma-
nent attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of
the vehicle for any reason.
Along with the seat belts, front airbags work with the
instrument panel knee bolsters to provide improved
protection for the driver and front passenger. Window
bags also work with seat belts to improve occupant
protection.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions.
NOTE:The passenger front airbag may not deploy even
when the driver front airbag has if the Occupant Classi-
fication System (refer to “Occupant Classification Sys-
tem” in this section) has determined the seat is empty or
is occupied by someone that is classified in the “child”
category. This could be a child, a teenager, or even a small
adult.
If your vehicle is so equipped, the window bag on the
crash side of the vehicle is triggered in moderate to
severe side collisions. But even in collisions where the

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

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.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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
grab handle) and AIRBAG warning light (located in
the instrument cluster) 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.)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. Both drivers and passengers

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 properly installed child re-
straint 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.
•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.
•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.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
