driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle is equipped with a right front passenger
Occupant Classification System (“OCS”) that is designed to
provide Passenger Advanced Front Air Bag output appro-
priate to the occupant’s seated weight input, as determined
by the OCS.
WARNING!
•No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air

bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The 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, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
260 SAFETY

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 collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper passen-
ger side of the instrument panel separate and fold out of
the way as the air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate while helping
to restrain the driver and front passenger.
Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s seated
weight, as determined by the OCS.The Occupant Classification System (OCS) consists of the
following:
•
Occupant Restraint Controller (ORC)
• Occupant Classification Module (OCM) and Sensor lo-
cated in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) and Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is located
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 passenger ’s most
probable classification. The OCM communicates this infor-
mation 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 properly wearing the seat belt.5
SAFETY 261

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 passen-
ger, 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.

passenger seat and never install a child restraint system,
including a rear-facing child restraint, in the front passen-
ger seat.
WARNING!
• Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in the rear seat
of a vehicle with a rear seat.
• Children 12 years or younger should always ride
buckled up in the rear seat of a vehicle with a rear
seat.
262 SAFETY

The OCS determines the front passenger ’s most probable
classification. The OCS estimates the seated weight on the
front passenger seat and where that weight is located. The
OCS communicates the classification status to the ORC.
The ORC uses the classification to determine whether the
Passenger Advanced Front Air Bag inflation rate should be
adjusted.
In order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and properly
wearing the seat belt. Properly seated passengers are:
•Sitting upright
• Facing forward
• Sitting in the center of the seat with their feet comfort-
ably on or near the floor
• Sitting with their back against the seatback and the
seatback in an upright position 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 determines the
most probable classification of the occupant that it detects.
Seated Properly

SAFETY 263

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 deployment 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 instrument
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.).
• Objects are lodged under the front passenger seat.
• Objects are lodged between the front passenger seat and
center console. •
Accessories that may change the seated weight on the
front passenger seat are attached to the front passenger
seat.
• Anything that may decrease or increase the front pas-
senger ’s seated weight.
The OCS determines the front passenger ’s most probable
classification. If an occupant 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, for example:

WARNING!
•If a child restraint system, child, small teenager or
adult in the front passenger seat is seated improp-
erly, the occupant may provide an output signal to
the OCS that is different from the occupant’s prop-
erly 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., backpacks,
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 prop-
erly seated weight input, which may result in serious
injury or death in a collision.
• Placing an object on the floor under the front pas-
senger 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.
Not Seated Properly
266 SAFETY

The passenger seat assembly contains critical OCS compo-
nents 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 compo-
nents must function as designed. Do not make any modi-
fications 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 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.
• 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.
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).
•
If it is necessary to modify the air bag system for
persons with disabilities, contact an authorized dealer.
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 front air bags.

SAFETY 267

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.
Supplemental Driver And Front Passenger Knee Air
Bags
This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the
steering column and a Supplemental Passenger Knee Air
Bag mounted in the instrument panel below the glove
compartment. The Supplemental Knee Air Bags provide
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.
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
Front Supplemental Seat-Mounted Side Air Bag
268 SAFETY

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!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.
Supplemental Side Air Bag Inflatable Curtains (SABICs)
This vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains (SABICs)
are located above the side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or “AIRBAG.” SABICs may help reduce the risk of head and other injuries
to front and rear seat outboard occupants in certain side
impacts, in addition to the injury reduction potential
provided by the seat belts and body structure.
The SABIC deploys downward, covering the side win-
dows. An inflating SABIC pushes the outside edge of the
headliner out of the way and covers the window. The
SABICs inflate with enough force to injure occupants if
they are not belted and seated properly, or if items are
Supplemental Side Air Bag Inflatable Curtain (SABIC)
Label Location

SAFETY 269

positioned in the area where the SABICs inflate. Children
are at an even greater risk of injury from a deploying air
bag.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.
WARNING!
•Do not mount equipment, or stack luggage or other
cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are lo-
cated should remain free from any obstructions.
• In order for the SABICs to work as intended, do not
install any accessory items in your vehicle which
could alter the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof racks that
require permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason. Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the sever-
ity and type of collision. The side impact sensors aid the
ORC in determining the appropriate response to impact
events. The system is calibrated to deploy the Side Air Bags
on the impact side of the vehicle during impacts that
require Side Air Bag occupant protection. In side impacts,
the Side Air Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle damage by
itself is not a good indicator of whether or not Side Air
Bags should have deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air bags
deploy.
