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.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
234 SAFETY

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.

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 a vehicle
with a rear seat.

SAFETY 235

WARNING!(Continued)
•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
• 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

WARNING!(Continued)
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 your authorized dealer for
service immediately.
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
5
SAFETY 239

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 your 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.
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).
240 SAFETY

WARNING!(Continued)
•Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or
killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. 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 rollover events. The
rollover sensing system determines if a rollover event may
be in progress and whether deployment is appropriate. In the event the vehicle experiences a rollover or near rollover
event, and deployment of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the seat belt
pretensioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.

WARNING! (Continued)
you. Do not modify the components or wiring, in-
cluding 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.
• 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, 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 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
authorized dealer.

SAFETY 247

WARNING!(Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at your authorized dealer as
soon as possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air
Bag System has been detected. It will stay on until the
fault is removed. If the light comes on intermittently or
remains on while driving, have your authorized dealer
service the vehicle immediately. Refer to “Occupant
Restraint Systems” in “Safety” for further information.
272 SAFETY

Defroster
Check operation by selecting the defrost mode and place the
blower control on high speed. You should be able to feel the
air directed against the windshield. See your authorized
dealer for service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only
use a floor mat that does not interfere with the operation of
the accelerator, brake or clutch pedals. Only use a floor mat
that is securely attached using the floor mat fasteners so it
cannot slip out of position and interfere with the accelera-
tor, brake or clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake,
or clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
•ALWAYS securely attach
your floor mat using the
floor mat fasteners. DO NOT install your floor mat

to confirm mat is secured using the floor mat fasten-
ers on a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE
before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle.
NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver ’s side floor mat on the driver ’s
side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch
pedal (if present) to check for interference. If your
floor mat interferes with the operation of any pedal,
or is not secure to the floor, remove the floor mat
from the vehicle and place the floor mat in your
trunk.

SAFETY 273

WARNING!(Continued)
•ONLY use the passenger ’s side floor mat on the
passenger ’s side floor area.
• ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.
