Occupant Classification Module (OCM) and Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is lo-
cated beneath the passenger seat cushion foam. Any
weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front pas-
senger ’s most probable classification. The OCM commu-
nicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and prop-
erly wearing the seat belt.
The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag if
the OCS estimates that:•
The front passenger seat is unoccupied or has very
light objects on it; or
• The front passenger seat is occupied by a small pas-
senger, including a child; or
• The front passenger seat is occupied by a rear-facing
child restraint; or
• The front passenger is not properly seated or his or her
weight is taken off of the seat for a period of time.

66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Lighter Weight Passengers (Including Small Adults)
When a lighter weight passenger, including a small adult,
occupies the front passenger seat, the OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag.
This does not mean that the OCS is working improperly.
Do not decrease OR increase the front passenger ’s
seated weight on the front passenger seat
The front passenger ’s seated weight must be properly
positioned on the front passenger seat. Failure to do so
may result in serious injury or death. The OCS deter-
mines the most probable classification of the occupant
that it detects.
The OCS will detect the front passenger ’s decreased or
increased seated weight, which may result in an adjusted
inflation rate of the Passenger Advanced Front Air Bag in a
collision. This does not mean that the OCS is working
improperly.
Decreasing the front passenger ’s seated weight on the
front passenger seat may result in a reduced-power
deployment of the Passenger Advanced Front Air Bag.
Increasing the front passenger ’s seated weight on the
front passenger seat may result in a full-power deploy-
ment of the Passenger Advanced Front Air Bag.
Examples of improper front passenger seating include:
•The front passenger ’s weight is transferred to another
part of the vehicle (like the door, arm rest or instru-
ment panel).
• The front passenger leans forward, sideways, or turns
to face the rear of the vehicle.
• The front passenger ’s seatback is not in the full upright
position.
• The front passenger carries or holds an object while
seated (e.g., backpack, box, etc.)

WARNING!(Continued)
•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.
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 Lightdoes 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 com-
ponents 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 your authorized dealer. Only Chrysler
Group 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.
• Do not use prior or future model year seat covers or
cushions not designated by Chrysler Group 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73
•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 Chrysler Group LLC .
WARNING!
Unapproved modifications or service procedures to
the passenger seat assembly, its related components,
seat cover or cushion may inadvertently change the
air bag deployment 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 collision. A
modified vehicle may not comply with required
Federal Motor Vehicle Safety Standards (FMVSS)
and/or Canadian Motor Vehicle Safety Standards
(CMVSS).
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the Advanced Front
Air Bags.
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.

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 de-
ployed. 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 pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint Controller
System serviced as well.
NOTE:
• Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment. •
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 ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition switch is turned to the “OFF” posi-
tion.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition switch is
turned to the “OFF” position.
• Unlock the doors automatically.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 81
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.
Air Bag Warning Light
The air bags must be ready to inflate for your protectionin a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The 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 bags 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 turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function 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 malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
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.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.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.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (“SRS”), the Redundant
Warning Light will illuminate on the instru-
ment panel.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 83
The Redundant Warning Light will stay on until the fault
is cleared. In addition, a single chime will sound to alert
you that the Redundant Warning Light has come on and
a fault has been detected. If the Redundant Warning
Light comes on intermittently or remains on while driv-
ing have an authorized dealer service the vehicle imme-
diately.
For additional information regarding the Redundant
Warning Light refer to the “Instrument Panel” section of
this manual.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, 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.
