JEEP LIBERTY 2012 KK / 2.G Repair Manual

WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
Supplemental Restraint System (SRS) — Air Bags
This vehicle has Advanced Front Air Bags for both the
driver and front passenger as a supplement to the seat
belt restraint systems. The driver’s Advanced Front Air
Bag is mounted in the steering wheel. The passenger’s
Advanced Front Air Bag is mounted in the instrument
panel, above the glove compartment. The words SRS/
AIRBAG are embossed on the air bag covers.
NOTE:These air bags are certified to the new Federal
regulations for Advanced Air Bags. The Advanced Front Air Bags have a multistage inflator
design. This allows the air bag to have different rates of
inflation that are based on the severity and type of
collision.

Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

NOTE:The passenger Advanced Front Air Bag may not
deploy, even when the driver Advanced Front Air Bag
has, if the Occupant Classification System (refer to Oc-
cupant Classification System) has determined the pas-
senger seat is empty or is occupied by someone that is
classified in the childsize category. This could be a
child, teenager, or even an adult.
WARNING!
•No objects should be placed over or near the air
bag on the instrument panel, because any such
objects could cause harm if the vehicle is in a
collision severe enough to cause the air bag to
inflate.
(Continued)
WARNING! (Continued)
•Do not put anything on or around the air bag
covers or attempt to manually open them. You may
damage the air bags and you could be injured
because the air bags may no longer be functional.
These protective covers for the air bag cushions
are designed to open only when the air bags are
inflating.
•Do not use accessory seat covers or place objects
between you and the side air bags; the perfor-
mance could be adversely affected and/or objects
could be pushed into you, causing serious injury.
•Do not drill, cut or tamper with the knee bolster in
any way.
•Do not mount any accessories to the knee bolster
such as alarm lights, stereos, citizen band radios,
etc.(Continued)

WARNING! (Continued)
•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
permanent attachments (bolts or screws) for instal-
lation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
Supplemental Side Air Bag Inflatable Curtain
(SABIC)
SABIC air bags may offer side-impact and vehicle roll-
over protection to front and rear seat outboard occupants
in addition to that provided by the body structure. Each
air bag features inflated chambers placed adjacent to the
head of each outboard occupant that reduce the potential
for side-impact head injuries. The SABIC air bags deploy
downward, covering both windows on the impact side.NOTE:
•Should a vehicle rollover occur, the pretensioners
and/or SABIC air bags on both sides of the vehicle
may deploy.
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•Being too close to the side air bags during deployment
could cause you to be severely injured or killed.
The system includes side impact sensors that are cali-
brated to deploy the side air bags during impacts that
require side air bag occupant protection.

WARNING!
•If your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtain
(SABIC), do not stack luggage or other cargo up
high enough to block the location of the SABIC.
The area where the SABIC is located should re-
main free from any obstructions.
•Do not use accessory seat covers or place objects
between you and the side air bags; the perfor-
mance could be adversely affected and/or objects
could be pushed into you, causing serious injury.
WARNING! (Continued)
•If your vehicle is equipped with SABIC air 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
permanent attachments (bolts or screws) for instal-
lation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bag.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved protection for the driver and front passenger. Side
air bags also work with seat belts to improve occupant
protection.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
TheORC is part of a Federally regulated safety system
required for this vehicle.
The ORC determines if deployment of the front and/or
side air bags in a frontal or side collision is required.
Based on the impact sensor’s signals, a central electronic
ORC deploys the Advanced Front Air Bags, Supplemen-
tal Side Air Bag Inflatable Curtain (SABIC), and front seat
belt pretensioners, as required, depending on the severity
and type of impact. Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on the severity and
type of collision. Advanced Front Air Bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions.
The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions. On
the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
The SABIC will not deploy in all side collisions. SABIC
deployment will depend on the severity and type of
collision.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all crashes,
and also are needed to help keep you in position, away
from an inflating air bag.
The ORC also monitors the readiness of the electronic
parts of the air bag system whenever the ignition switch
is in the START or ON/RUN positions. If the key is in the
LOCK position, in the ACC position, or not in the
ignition, the air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.Also, the ORC turns on the “Air Bag Warning
Light” for four to eight seconds for a self-check
when the ignition is first turned to ON/RUN.
After the self-check, the “Air Bag Warning
Light” will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the “Air Bag Warning
Light” either momentarily or continuously. A single
chime will sound if the light comes on again after initial
startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Occupant Classification System (OCS)
The OCS is part of a Federally regulated safety system
required for this vehicle. It is designed to turn off the
passenger Advanced Front Air Bag for an empty seat and
for occupants classified in a category other than an adult.
This could be a child, teenager, or even an adult.
NOTE:Children 12 years or younger should always
ride buckled up in a rear seat in an appropriate child
restraint.
•Occupant Classification Module (OCM)
The OCM is located 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 ORC. The ORC uses the
occupant category to determine whether the passenger
Advanced Front Air Bag should be turned off. It also
determines the rate of air bag inflation during a collision.
•Weight Sensors
Your vehicle has four Weight Sensors located between the
seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•Passenger Air Bag Disable (PAD) Indicator Light
The PAD Indicator Light (an amber light located in the
center of the instrument panel) tells the driver and front
passenger when the passenger Advanced Front Air Bag is
turned off. The PAD Indicator light illuminates the words
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

“PASS AIR BAG OFF” to show that the passenger
Advanced Front Air Bag will not inflate during a collision
requiring air bag deployment. When the right front
passenger seat is empty or when very light objects are
placed on the seat, the passenger air bag will not inflate
even though the PAD indicator light is not illuminated.The PAD indicator light should not be illuminated when
an adult passenger is properly seated in the front passen-
ger seat. In this case, the passenger Advanced Front Air
Bag is ready to be inflated if a collision requires an air bag
deployment.
For all other occupants, the PAD indicator light will be
illuminated indicating that the passenger Advanced
Front Air Bag is turned off and will not inflate.
NOTE:
Even though this vehicle is equipped with an
occupant classification system, children 12 years or
younger should always ride buckled up in a rear seat in
an appropriate child restraint (refer to “Child Re-
straints”).
