JEEP WRANGLER 2008 JK / 3.G Workshop Manual

The Enhanced Warning System (BeltAlert) can be reac-
tivated 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 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 seat belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and stow the seat belt extender
when not needed.

Driver And Front Passenger Supplemental
Restraint Systems (SRS)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 front passenger airbag is mounted in
the instrument panel, above the glove compartment. The
letters SRS 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 multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity.

If the vehicle is equipped with side airbags, they are
located inside the driver and front passenger seats, and
their covers are also labeled SRS.
NOTE:Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.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 because the airbags are
no longer functional. These protective covers for the
airbag cushions are designed to open only when the
airbags are inflating.
• If your vehicle is equipped with side airbags, do not use
accessory seat covers or place objects between you and
the side airbags; the performance could be adversely
affected and/or objects could be pushed into you, caus-
ing serious injury.
• If your vehicle is equipped with side airbags, do not
attach cup holders or any other objects on or around the
door. The inflating side airbag could drive the objects
into occupants, causing serious injury.
• Do not cover or place items on the airbag covers. These
items may cause serious injury during inflation.
• Do not store or place items under the front seats. You
may damage the airbag wiring harnesses.
Side Airbag Location
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The front airbags have a multistage inflator design. This
allows the airbag to have different rates of inflation that
are based on collision severity. Along with the seat belts,
front airbags work with the instrument panel knee bol-
sters to provide improved protection for the driver and
front passenger. Side airbags 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.
If your vehicle is so equipped, the side airbag on the
crash side of the vehicle is triggered in moderate to
severe side collisions. In certain types of collisions, both
the front and side airbags may be triggered. 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.
Infants in rear facing child restraints should
NEVERride
in the front seat of a vehicle with a passenger airbag. An
airbag deployment could cause severe injury or death to
infants in that position.
Children that are not big enough to properly wear the
vehicle seat belt should be secured in the rear seat, in a
child restraint or belt-positioning booster seat. Older
children who do not use child restraints or belt-
positioning booster seats should ride properly buckled
up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.
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. Refer to “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 front airbags room to
inflate.
4. If your vehicle has side airbags, do not lean against the
door, airbags will inflate forcefully into the space be-
tween 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 instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
•If the vehicle has side airbags, they also need room
to inflate. Do not lean against the door. Sit upright
in the center of the seat.

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control (ORC) Module
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Front Seat-Mounted Side Airbags (If Equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Remote Side Impact Acceleration Sensors (If
Equipped)
•Driver Seat Track Position Sensors
•Driver and Front Passenger Seat Belt Pretensioner
How The Airbag System Works
•
TheOccupant Restraint Control (ORC) Module de-
termines if a frontal or side collision is severe enough
to require the front and/or side airbags to inflate. The
front airbag inflators are designed to provide different
rates of airbag inflation from direction provided by the
ORC.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK 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 for six to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Airbag Warning Light will
turn off. 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
immediately.
•The Driver and Passenger Airbag/Inflator Units are
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 to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity. 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 to 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 front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•TheSide Impact (SRS) Seat-Mounted Side Airbags
(If Equipped) are designed to activate only in certain
side collisions.
The ORC determines if a side collision is severe
enough to require the side airbags to inflate.
The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON positions. These include all of the items previously
mentioned.
In moderate to severe side collisions, the side airbag
inflator on the crash side of the vehicle is triggered,
releasing a quantity of nontoxic gas. The inflating side
airbag exits through the seat seam into the space between
the occupant and the door. The side airbag moves at a
very high speed and with such a high force, that it could
injure you if you are not seated properly, or if items are
positioned in the area where the side airbag inflates. This
especially applies to children.•The Knee Impact Bolsters help protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
If A Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) Module detects a
moderate-to-severe frontal collision, to help restrain the
driver and front passenger, and then to immediately
deflate.
NOTE: A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front

passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
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 manufacturer’s instruc-
tions 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 pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. The hazard
lights will flash and the fuel will be cut off to the engine.
In addition, after the vehicle has stopped moving, the
interior lights will illuminate to aid visibility and remain
lit until the ignition switch is turned off.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
• Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper or vehicle body structure.
• You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
• It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.
