2012 JEEP WRANGLER Owners Manual

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 is required in a frontal or side collision.
Based on the impact sensor’s signals, a central electronic
ORC deploys the Advanced Front Air Bags, Supplemen-
tal Seat-Mounted Side Air Bags (SAB) — if equipped, and
front seat belt pretensioners, as required, depending on
several factors, including 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 several factors,
including 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 side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63

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 on. 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.
64 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.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation ratesare possible, based on the collision type and 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 air bags inflate to their full size. The air bags fully
inflate in about 50 to 70 milliseconds. This is about half of
the time it takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.Supplemental Seat-Mounted Side Air Bags (SAB)
Inflator Units — If Equipped
The Supplemental Seat-Mounted Side Air Bags Inflator
Units (if equipped) are designed to activate only in
certain side collisions.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

The ORC determines if a side collision requires the side
air bags to inflate, based on several factors, including the
severity and type of collision.
Based on several factors, including the severity and type
of collision, the side air bag inflator on the crash side of
the vehicle is triggered, releasing a quantity of non-toxic
gas. The inflating SAB exits through the seat seam into
the space between the occupant and the door. The SAB
fully inflate in about 10 milliseconds. The side air bag
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 air bag
inflates. This especially applies to children.
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.
Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Unlock the doors automatically.
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON to IGN OFF.
If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
•The nylon air bag material may sometimes cause
abrasions and/or skin reddening to the driver and
front passenger as the air bags 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 air bags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag 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 in-
structions for cleaning.
•Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision, the
air bags will not be in place to protect you.

WARNING!
•Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the
air bags, seat belt pretensioner, and seat belt
retractor assembly replaced by an authorized
dealer immediately. Also, have the Occupant Re-
straint Controller (ORC) system serviced as well.(Continued)
WARNING! (Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or
may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat, includ-
ing your trim cover and cushion, needs to be
serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to your authorized dealer. Only
manufacturer approved seat accessories may be
used. If it is necessary to modify the air bag system
for persons with disabilities, contact your autho-
rized dealer.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag 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,
or add aftermarket side steps or running boards.
•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 air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free, if any of
the following occurs, have an authorized dealer service
the air bag system immediately.
•The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position.
•The Air Bag Warning Light remains on after the four to
eight-second interval.
•The Air Bag Warning Light comes on intermittently or
remains on while driving.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•How various systems in your vehicle were operating;
•Whether or not the driver and passenger safety belts
were buckled/fastened;
•How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
•How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation.
