WARNING!(Continued)
•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.
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.

SAFETY 247

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.
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.

* It is possible for a child to be classified as an adult,
allowing a full-power Passenger Advanced Front Air Bag
deployment. Never allow children to ride in the front
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.
(Continued)
WARNING! (Continued)
•Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.
• Children 12 years or younger should always ride
buckled up in a vehicle with a rear seat.
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
5
SAFETY 249

•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.
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.
Seated Properly
250 SAFETY

•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

WARNING! (Continued)
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.

SAFETY 253

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 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.
• 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.
