JEEP LIBERTY 2004 KJ / 1.G Service Manual

WARNING!
Position the shoulder belt height adjusters so that
the belt rests across the middle of your shoulder.
Failure to adjust the safety belt properly could
reduce the effectiveness of the seat belt and increase
the risk of injury in a collision.
As a guide, if you are shorter than average, you will
prefer a lower position, and if you are taller than average,
you'll prefer a higher position. When you release the
anchorage, try to move it up or down to make sure that
it is locked in position.
Automatic Locking Mode Ð If Equipped
In this mode, the shoulder belt is automatically pre-
locked. The belt will still retract to remove any slack in
the shoulder belt.

When To Use The Automatic Locking Mode
Anytime a child safety seat is installed in a passenger
front or outboard rear seating position (if equipped).
Children 12 years old and under should be properly
restrained in the rear seat whenever possible.
How To Use The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until
the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts, you will
hear a clicking sound. This indicates the safety belt is
now in the automatic locking mode.
How to Disengage The Automatic Locking Mode
Disconnect the combination lap/shoulder belt and allow
it to retract completely to disengage the automatic lock-
ing mode and activate the vehicle sensitive (emergency)
locking mode.
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!
²After a vehicle collision, the driver and front
passenger outboard seat belt system must be
checked by a qualified technician to verify that
the ªautomatic locking retractorº feature for child
seats is still functioning properly. In addition, all
seat belts should be checked for proper function.
²The belt and retractor assembly must be replaced
if the seat belt assembly ªautomatic locking re-
tractorº feature or any other seat belt function is
not working properly when checked according to
the procedures in the Service Manual.
²Failure 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).
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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Enhanced Warning System (BeltAlert) can be reacti-
vated by repeating this procedure.
NOTE:Although the Enhanced Warning System (BeltA-
lert) 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) Ð AirbagsThis 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
the instrument panel, above the glove compartment. The
words SRS/AIRBAG are embossed on the airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
The front airbags have a multi stage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
Also, the front passenger airbag is certified to the Federal
regulations that define Occupant Classification (Refer to
ªOccupant Classification Systemº in this section).
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

This vehicle may also be equipped with window bags to
protect the driver, front, and rear passengers sitting next
to a window. If the vehicle is equipped with window
bags, they are located above the side windows. Their
covers are also labeled SRS AIRBAG.
NOTE:Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.WARNING!
²Do 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.
²If 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.
²If 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 ªOccupant Classification Sys-
temº in this section) has determined the seat is empty or
is occupied by someone that is classified in the ªchildº
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
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 ªChild Restraintº in this section.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

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
