Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the ignition switch is in the OFF position
or in the ACC position, 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 bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
first in the ON/RUN position. 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 to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system

Not Seated Properly
Not Seated Properly
The Air Bag Warning Light in the instrument
panel will turn on whenever the OCS is unable to
classify the front passenger seat status. A
malfunction in the OCS may affect the operation of
the air bag system.
If the Air Bag Warning Light does not come on,
or stays on after you start the vehicle, or it comes
on as you drive, take the vehicle to an authorized
dealer for service immediately.
The passenger seat assembly contains critical OCS
components that may affect the Passenger
Advanced Front Air Bag inflation. In order for the
OCS to properly classify the seated weight of a
front seat passenger, the OCS components must
function as designed. Do not make any
modifications to the front passenger seat
components, assembly, or to the seat cover. If the
seat, trim cover, or cushion needs service for any
reason, take the vehicle to an authorized dealer.
Only FCA US LLC approved seat accessories may
be used.
The following requirements must be strictly
followed:
Do not modify the front passenger seat
assembly or components in any way.
WARNING!
If a child restraint system, child, small teen
-
ager or adult in the front passenger seat is
seated improperly, the occupant may provide
an output signal to the OCS that is different
from the occupant’s properly seated weight
input. This may result in serious injury or death
in a collision.
Always wear your seat belt and sit properly,
with the seatback in an upright position, your
back against the seatback, sitting upright,
facing forward, in the center of the seat, with
your feet comfortably on or near the floor.
Do not carry or hold any objects (e.g., back -
packs, boxes, etc.) while seated in the front
passenger seat. Holding an object may
provide an output signal to the OCS that is
different than the occupant’s properly seated
weight input, which may result in serious injury
or death in a collision.
Placing an object on the floor under the front
passenger seat may prevent the OCS from
working properly, which may result in serious
injury or death in a collision. Do not place any
objects on the floor under the front passenger
seat.

Do not use prior or future model year seat
covers or cushions not designated by FCA US
LLC for the specific model being repaired.
Always use the correct seat cover and cushion
specified for the vehicle.
Do not replace the seat cover or cushion with an
aftermarket seat cover or cushion.
Do not add a secondary seat cover or mat.
At no time should any Supplemental Restraint
System (SRS) component or SRS related
component or fastener be modified or replaced
with any part except those which are approved
by FCA US LLC.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column. The
Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact by
working together with the seat belts,
pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs). Supplemental Seat-Mounted Side Air Bags (SABs)
are located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
injury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag.
WARNING!
Unapproved modifications or service proce-
dures to the passenger seat assembly, its
related components, seat cover or cushion
may inadvertently change the air bag deploy -
ment in case of a frontal collision. This could
result in death or serious injury to the front
passenger if the vehicle is involved in a colli -
sion. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Stan -
dards (FMVSS) and/or Canadian Motor
Vehicle Safety Standards (CMVSS).
If it is necessary to modify the air bag system
for persons with disabilities, contact an autho -
rized dealer.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.

Occupant Classification System
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all colli -
sions. 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 air bag material may sometimes cause
abrasions and/or skin reddening to the occu -
pants 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 imme -
diately.
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 instructions 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.
NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy -
ment.
After any collision, the vehicle should be taken
to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will determine
whether to have the Enhanced Accident Response
System perform the following functions:
Cut off fuel to the engine (if equipped).
Cut off battery power to the electric motor (if
equipped).
Flash hazard lights as long as the battery has
power.
Turn on the interior lights, which remain on as
long as the battery has power or for 15 minutes
from the intervention of the Enhanced Accident
Response System.
Unlock the power door locks.
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the
air bags, seat belt pretensioners, and the seat
belt retractor assemblies replaced by an
authorized dealer immediately. Also, have the
Occupant Restraint Controller System serviced
as well.

NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the
engine.
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System 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 performed.
The EDR is designed to record data related to
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 compo-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
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.
Do not attempt to modify any part of your air
bag system. The air bag may inflate acciden -
tally or may not function properly if modifica -
tions are made. Take your vehicle to an
authorized dealer for any air bag system
service. If your seat, including 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 an
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 an autho -
rized dealer.
WARNING!

SAFETY223
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 condi -
tions and no personal data (e.g., name, gender,
age, and crash location) are recorded. However,
other parties, such as law enforcement, could
combine the EDR data with the type of personally
identifying data routinely acquired during a crash
investigation. To read data recorded by an EDR, special
equipment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer, other parties, such as law
enforcement, that have the special equipment,
can read the information if they have access to the
vehicle or the EDR.
CHILD RESTRAINTS
Everyone in your vehicle needs to be buckled up at
all times, including babies and children. Every
state in the United States, and every Canadian
province, requires that small children ride in
proper restraint systems. This is the law, and you
can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to
crash statistics, children are safer when properly
restrained in the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost
large enough for an adult safety belt. Always check
the child seat Owner’s Manual to make sure you
have the correct seat for your child. Carefully read
and follow all the instructions and warnings in the
child restraint Owner’s Manual and on all the
labels attached to the child restraint.
Before buying any restraint system, make sure that
it has a label certifying that it meets all applicable
Safety Standards. You should also make sure that
you can install it in the vehicle where you will use it.
NOTE:
For additional information, refer to

WARNING!
In a collision, an unrestrained child can become
a projectile inside the vehicle. The force required
to hold even an infant on your lap could become
so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured or killed. Any child riding
in your vehicle should be in a proper restraint for
the child’s size.
