belt JEEP LIBERTY 2005 KJ / 1.G User Guide

Energy Management Feature
This vehicle has a safety belt system with an energy
management feature at the driver and front passenger
seating positions to help further reduce the risk of injury
in the event of a head-on collision.
This safety belt system has a retractor assembly that is
designed to pay out webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.WARNING!
•After a vehicle collision, the driver and front
passenger outboard seat belt system must be
checked by a qualified technician to verify that
the “automatic locking retractor” feature for child
seats is still functioning properly. In addition, all
seat belts should be checked for proper function.
•The belt and retractor assembly must be replaced
if the seat belt assembly “automatic locking re-
tractor” feature or any other seat belt function is
not working properly when checked according to
the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.

Seat Belt Pretensioners
The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves the performance of the
seat belt by assuring that the belt is tight around the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the front Airbag
Control Module. Like the front airbags, the pretensioners
are a single use item. After a collision that is severe
enough to deploy the airbags and pretensioners, they
must be replaced.
Enhanced Driver Seat Belt Use Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within 60
seconds of starting the vehicle and if the vehicle speed is
greater than 5 mph (8 km/h), the Enhanced Warning
System (BeltAlert) will alert the driver to buckle their seat
belt. The driver should also instruct all other occupants to
buckle their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to
chime and flash the Seat Belt Warning Light for 96
seconds or until the driver’s seat belt is buckled.
The Enhanced Warning System (BeltAlert) will be reacti-
vated if the driver’s seat belt is unbuckled for more than
10 seconds and the vehicle speed is greater than 5 mph (8
km/h).
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Enhanced Warning System (BeltAlert) can be en-
abled or disabled by your authorized dealer or by
following these steps:
NOTE:The following steps must occur within the first
60 seconds of the ignition switch being turned to the ON
or START position. The manufacturer does not recom-
mend deactivating the Enhanced Warning System
(BeltAlert).
1. Turn the ignition switch to the OFF position, and
buckle the driver’s seat belt.
2. Turn the ignition key to the ACCESSORY/RUN posi-
tion (engine does not need to be running), and wait for
the Seat Belt Warning Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle
and then re-buckle the driver’s seat belt at least three
times within 10 seconds, ending with the seat belt
buckled.4. Turn the ignition key to the OFF position. A single
chime will sound to signify that you have successfully
completed the programming.
The Enhanced Warning System (BeltAlert) can be reacti-
vated by repeating this procedure.
NOTE:Although the Enhanced Warning System
(BeltAlert) has been deactivated, the Seat Belt Warning
Light will continue to illuminate while the driver’s seat
belt remains unfastened.
Seat Belts and Pregnant Women
We recommend that pregnant women use the seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the belt
across the thighs and as snug across the hips as possible.
Keep the belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.

Seat Belt Extender
If a seat belt is too short, even when fully extended and
when the adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. This
extender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender and store it.
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.
Driver And Front Passenger Supplemental
Restraint Systems (SRS) — Airbags
This vehicle has airbags for both the driver and right
front passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
steering wheel. The passenger side airbag is mounted in

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
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

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

•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 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 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.

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.
