2007 JEEP LIBERTY airbag disable

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
airbags work, you need the seat belts to keep you in the
right position for the airbags to protect you properly.
Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag.
1. Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
Infants in rear-facing child restraints shouldNEVERride
in the front seat of a vehicle with a passenger front airbag.
An airbag deployment can cause severe injury or death to
infants in that position.
If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move the
seat as far back as possible, and use the proper child
restraint. See “Child Restraint” in this section.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.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under “If
You Need Assistance” in Section 9 of this manual.

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

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 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.

•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.
