Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control (ORC)
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Side Curtain Airbags above Side Windows
•Side Remote Acceleration Sensors
•Driver Side Seat Track Position Sensor
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
How the Airbag System Works
•
TheOccupant Restraint Control (ORC)determines if
a frontal, side, or rollover collision is severe enough to
require the front and/or side airbags to inflate. The
front airbag inflators are designed to provide different
rates of airbag inflation from direction provided by the
ORC. The ORC will detect roll overs, not rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

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
immediately.
•As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
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 instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioners, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. The hazard
lights will flash and the fuel will be cut off to the engine.
In addition, after the vehicle has stopped moving, the
interior lights will illuminate to aid visibility and remain
lit until the ignition switch is turned off.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Airbag Warning Light does not come on during the six
to eight seconds after the ignition switch is first turned
on,
•Remains on after the six to eight second interval, or
•Flickers, or comes on and remains on for any period of
time while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuseblock for blown fuses. Refer to “Fuses” in Section 7 of this
manual. See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to one-quarter second of high-speed
deceleration data during and/or after airbag deployment
or near-deployment. EDR data are ONLY recorded if an
airbag deploys, or nearly deploys, and are otherwise
unavailable.
NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.

WARNING!
•Rearward-facing child seats must NEVER be used
in the front seat of a vehicle with the front passen-
ger airbag unless the airbag is turned off. An
airbag deployment could cause severe injury or
death to infants in this position.
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. Chrysler LLC also recommends that you
try a child restraint in the vehicle seats where you will
use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Except for the second row center seating position, all
passenger seat belts are equipped with cinching latch
plates. The second row center position has an auto-
matic locking retractor. Both types of seat belts are
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

designed to keep the lap portion tight around the child
restraint so that it is not necessary to use a locking clip.
If the seat belt has a cinching latch plate, pulling up on
the shoulder portion of the lap/shoulder belt will
tighten the belt (the cinching latch plate will keep the
belt tight, however, any seat belt system will loosen
with time, so check the belt occasionally and pull it
tight if necessary). For the second row center seat belt
with the automatic locking retractor, pull the belt from
the retractor until there is enough allowance to pass it
through the child restraint and slide the latch plate
into the buckle. Then, pull the belt until it is fully
extended from the retractor. Allow the belt to return
into the retractor, pulling on the excess webbing to
tighten the lap portion about the child restraint. For
additional information, refer toAutomatic Locking
Modeearlier in this section.
•In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because thebuckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.
•If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
•When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seatbacks and
cause serious personal injury.

WARNING!
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of an infant or
child restraint. The child could be badly injured or
killed. Follow the manufacturer’s directions exactly
when installing an infant or child restraint.
Installing Child Restraints Using the Vehicle Seat
Belts
The passenger seat belts are equipped with either cinch-
ing latch plates or automatic locking retractors, which are
designed to keep the lap portion tight around the child
restraint so that it is not necessary to use a locking clip. If
the seat belt has a cinching latch plate, pulling up on the
shoulder portion of the lap/shoulder belt will tighten the
belt. The cinching latch plate will keep the belt tight,
however, any seat belt system will loosen with time, so
check the belt occasionally and pull it tight if necessary.
For seat belts having an Automatic Locking Retractor
(ALR), pull the belt from the retractor until there is enough
allowance to pass it through the child restraint and slide
the latch plate into the buckle. Then, pull the belt until it is
fully extended from the retractor. Allow the belt to return
into the retractor, pulling on the excess webbing to tighten
the lap portion about the child restraint. Refer to “Auto-
matic Locking Mode” earlier in this section.
In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path opening
on the restraint. Disconnect the latch plate from the
buckle and twist the short buckle-end belt several times
to shorten it. Insert the latch plate into the buckle with the
release button facing out.
If the belt still can’t be tightened, or if by pulling and
pushing on the restraint loosens the belt, you may need
to do something more. Disconnect the latch plate from
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
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.
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 objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

forward or rearward to resist damage. The hinges have
three detent positions: full forward, full rearward and
normal.
Driver’s And Front Passenger Outside Automatic
Dimming Mirrors — If Equipped
If your vehicle is equipped with outside automatic dim-
ming mirrors, they will operate when the inside auto-
matic dimming mirror is on. The outside mirrors operate
off the inside mirror switch and will automatically adjust
for annoying headlight glare when the inside mirror
does.
Outside Power Mirrors
The power mirror switch is located on the drivers door
trim panel next to the power door lock switch. A rotary
knob selects the left mirror, right mirror or off position.After selecting a mirror, move the knob in the same
direction you want the mirror to move. Use the center off
