Supplemental Side Airbag Inflatable Curtain
(SABIC) — If Equipped
SABIC airbags offer side-impact and vehicle rollover
protection to front and rear seat outboard occupants in
addition to that provided by the body structure. Each
airbag features inflated chambers placed adjacent to the
head of each outboard occupant that reduce the potential
for side-impact head injuries. The curtains deploy down-
ward, covering both windows on the impact side.NOTE:
•Should a vehicle rollover occur, the pretensioners
and/or SABIC airbags on both sides of the vehicle
may deploy.
•Airbag covers may not be obvious in the interior trim;
but they will open during airbag deployment.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

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.

deploy the SABIC airbags, depending on severity and
type of collision. In these events, the ORC will deploy the
SABIC only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to inflate the side
curtain airbag. The inflating side curtain airbag pushes
the outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30 ms
(about one-quarter of the time that it takes to blink your
eyes) with enough force to injure you if you are not belted
and seated properly, or if items are positioned in the area
where the side curtain airbag inflates. This especially
applies to children. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an airbag should have deployed.
NOTE:In a rollover the pretensioners and/or SABIC
airbags may deploy on both sides of the vehicle.Front and Side Impact Sensors
In front and side impacts, impact sensors aid the ORC in
determining appropriate response to impact events. Ad-
ditional sensors in the ORC determine the level of airbag
deployment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.

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

•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). Convertible child seats often
have a higher weight limit in the rearward-facing
direction than infant carriers do, so they can be used
rearward-facing by children who weigh more than
20 lbs (9 kg) but are less than one year old. Both types
of child restraints are held in the vehicle by the
lap/shoulder belt or the LATCH child restraint an-
chorage system (Refer to LATCH — Child Seat An-
chorage System.)
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.(Continued)
WARNING! (Continued)
•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 re-
straint in the front seat may be struck by a deploy-
ing passenger airbag which may cause severe 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

the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
6. Airbag Warning Light This light turns on and remains on for six to
eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
160 UNDERSTANDING YOUR INSTRUMENT PANEL

Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
should notbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the driveshaft
is removed. Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
