3. Allow the belt to retract. As the belt retracts, you will
hear a clicking sound. This indicates the safety belt is
now in the Automatic Locking Mode.
How to Disengage The Automatic Locking Mode
Disconnect the combination lap/shoulder belt from the
buckle and allow it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle sensi-
tive (emergency) locking mode.
Seat Belt Pretensioners — If Equipped
The seat belts for both front seating positions may be
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of a collision.
These devices improve the performance of the seat belt
by assuring that the belt is tight about the occupant early
in a collision. Pretensioners work for all size occupants,
including those in child restraints.NOTE:
These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the airbags, the pretension-
ers are single use items. After a collision deploys the
airbags and/or pretensioners, a deployed airbag and/or
pretensioner must be replaced immediately.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within
60 seconds of starting the vehicle and if the vehicle speed
is greater than 5 mph (8 km/h), the BeltAlert will alert
the driver to buckle the seat belt. The driver should also
instruct all other occupants to buckle their seat belts.
Once the warning is triggered, the BeltAlert will con-
tinue to chime and flash the Seat Belt Reminder Light for
96 seconds or until the driver’s seat belt is buckled. The

The system includes sensors adjacent to both front and
rear seat occupants that are calibrated to deploy the
SABIC airbags during impacts that require airbag occu-
pant protection.
WARNING!
•If your vehicle is equipped with left and right Side
Airbag Inflatable Curtain (SABIC), do not stack
luggage or other cargo up high enough to block
the location of the SABIC. The area where the side
curtain airbag is located should remain free from
any obstructions.
•Do not use accessory seat covers or place objects
between you and the side airbags; the performance
could be adversely affected and/or objects could
be pushed into you, causing serious injury.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position everyone for
the best interaction with the Advanced Front Airbag.
Along with seat belts and pretensioners, Advanced Front
Airbags work with the knee bolsters to provide improved
protection for the driver and front passenger. Side airbags
also work with seat belts to improve occupant protection.
Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag:
Children 12 years old and younger should always ride
buckled up in a rear seat.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Advanced Front Airbags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions. On the other
hand, depending on the type and location of impact,
Advanced Front Airbags may deploy in crashes with
little vehicle front-end damage but that produce a severe
initial deceleration.
The side airbags will not deploy in all side collisions. Side
airbag deployment will depend on the severity and type
of collision.
Because airbag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an airbag should have
deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating airbag.The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON position. 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.
The ORC contains a backup power supply system that
may deploy the airbags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Airbag Warning
Light in the instrument panel for approxi-
mately six to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Airbag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the Airbag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.

•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
If a Deployment Occurs
The front airbags are designed to deflate immediately
after deployment.
NOTE:Front and/or side airbags will not deploy in all
collisions. This does not mean something is wrong with
the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
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 non-toxic 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 in-
structions for cleaning.
Do not drive your vehicle after the airbags have de-
ployed. If you are involved in another collision, the
airbags will not be in place to protect you.

WARNING! (Continued)
•Do not attempt to modify any part of your ad-
vanced airbag system. The airbag may inflate
accidentally or may not function properly if modi-
fications are made. Take your vehicle to an autho-
rized dealer for any advanced airbag system ser-
vice. If your seat, including your trim cover and
cushion, needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accesso-
ries may be used. If it is necessary to modify an
advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The Airbag Warning Light does not come on for
approximately six to eight seconds when the ignition
switch is first turned ON.
•The light remains on after the approximate six to
eight-second interval.
•The light comes on and 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. The airbags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

located on the inside of the fuse block cover for the
proper airbag fuses. 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 list below) in an event data recorder prior to the
moment of airbag deployment, or near deployment (if
applicable), and up to a quarter second of either high-
speed deceleration data or change in velocity during
and/or after airbag deployment or near-deployment.
EDR data is ONLY recorded if an airbag deploys, or
nearly deploys, and is otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by Chrysler Group LLC and others to learn more
about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
Chrysler Group LLC, such investigations may be re-
quested by customers, insurance carriers, government
officials, and professional crash researchers, such as those
associated with universities, and with hospital and insur-
ance organizations.
In the event that an investigation is undertaken by
Chrysler Group LLC (regardless of initiative), the com-
pany or its designated representative will first obtain
permission of the appropriate custodial entity for the
vehicle (usually the vehicle owner or lessee) before

Standards. Chrysler Group 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
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 thebelt 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 around the child restraint. For
additional information, refer to
Automatic Locking
Mode.
•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.

means of adjusting the tension in the strap. Forward-
facing toddler restraints and some rear-facing infant
restraints will also be equipped with a tether strap, a
hook for attachment to the tether strap anchorage and a
means of adjusting the tension of the strap.
First, loosen the adjusters on the lower straps and on the
tether strap so that you can more easily attach the hooks
or connectors to the vehicle anchorages. Next, attach the
lower hooks or connectors over the top of the anchorage
bars, pushing aside the seat cover material. Then, locate
the tether anchorage directly behind the seat where you
are placing the child restraint and attach the tether strap
to the anchorage, being careful to route the tether strap to
provide the most direct path between the anchor and the
child restraint. Finally, tighten all three straps as you
push the child restraint rearward and downward into the
seat, removing slack in the straps according to the child
restraint manufacturer’s instructions.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.
