WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions, the airbags won’t deploy at all.
Always wear your seat belts even though you have
airbags.
•Being too close to the steering wheel or instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
•If the vehicle has supplemental side curtain air-
bags and/or supplemental front seat-mounted side
airbags, they also need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•Side Remote Acceleration Sensors (if equipped)
•Airbag Warning Light
•Driver Airbag
•Front Passenger Airbag
•Supplemental Side Curtain Airbags above Side Win-
dows (if equipped)
•Supplemental Front Seat-Mounted Side Airbags (if
equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring

•Seat Belt Reminder Light
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
How the Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC will not
detect rollover.
•For vehicles so equipped, the ORC also determines if a
side impact is severe enough to deploy the supple-
mental side curtain airbag and/or supplemental front
seat-mounted side airbag as required for each type of
impact.
•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 they will
not inflate.
•The ORC also turns on the Airbag Warning
Light in the instrument panel for six to eight
seconds as 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 continu-
ously. A single chime will sound if the light comes on
again after initial start-up.

•The light remains on or flickers after the six to eight
second interval.
•The light flickers or comes on and remains on while
driving.
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 a quarter second of high-speed
deceleration data during and/or after airbag deploy-
ment. EDR data are ONLY recorded if an airbag deploys,
or nearly deploys, and are 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 LLC and others to learn more about the
possible causes of crashes and associated injuries in order
to assess and improve vehicle performance. In addition
to crash investigations initiated by Chrysler LLC, such
investigations may be requested by customers, insurance
carriers, government officials, and professional crash
researchers, such as those associated with universities,
and with hospital and insurance organizations.
In the event that an investigation is undertaken by
Chrysler LLC (regardless of initiative), the company or its
designated representative will first obtain permission of
the appropriate custodial entity for the vehicle (usually
the vehicle owner or lessee) before accessing the elec-
tronic data stored, unless ordered to download data by a

The Headlights On with Wipers feature can be enabled or
disabled. Refer to ”Headlights On with Wipers,” under
“Personal Settings (Customer-Programmable Features)”
under “Electronic Vehicle Information Center (EVIC)” in
Section 4.
Rain Sensing Wipers
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. This
feature is especially useful for road splash or over spray
from the windshield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of the six
intermittent wiper settings to activate this feature.
The sensitivity of the system is adjustable from the
multifunction lever. Wiper delay position 1 is the least
sensitive and wiper delay position 6 is the most sensitive.
Choose setting 3 or 4 for normal rain conditions. Choose
setting 2 or 1 if you desire less wiper sensitivity. Choosesetting 5 or 6 if you desire more sensitivity. Place the
multifunction lever in the off position when not using the
system.
NOTE:
•The rain sensing feature will not operate when the
wiper speed is in the low or high position.
•The rain sensing feature may not function properly
when ice or dried salt water is present on the wind-
shield.
•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•The rain sense feature can be enabled or disabled.
Refer to “Rain Sensing Intermittent Wipers,” under
“Personal Settings (Customer-Programmable Fea-
tures)” under “Electronic Vehicle Information Center
(EVIC)” in Section 4.

WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions and you
could lose control. An accident could be the result.
Do not use Electronic Speed Control in heavy traffic
or on roads that are winding, icy, snow-covered or
slippery.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes an infrared
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically to
maintain a preset following distance, while matching
the speed of the vehicle ahead.
152 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed.
Setting the Following Distance in ACC
The specified following distance for ACC can be set by
varying the distance setting between long, medium, and
short. Using this distance setting and the vehicle speed,
ACC calculates and sets the distance to the vehicle ahead.
This distance setting displays in the EVIC.
To change the distance setting, push the lever away from
you (DISTANCE) and release. Each time this is done, the
distance setting adjusts between long, medium, and
short.
1 — Sensor Bars. Default Distance Setting is Three Bars = Long. 160 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically to maintain the distance setting, regardless of
the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
•The vehicle ahead moves out of your lane or view of
the sensor.
•The vehicle ahead slows to a speed below 15 mph
(24 km/h) and the system automatically disengages
itself.
•The distance setting is changed.
•The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.

If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located behind the grille,
slightly offset from the center of the grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:•Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
•Do not remove any screws from the sensor or the
sensor mount. Doing so could cause an ACC system
malfunction or failure and require a sensor realign-
ment.
•If the sensor is damaged due to an accident, see your
authorized dealer for service.
•Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “CRUISE
OFF” state and will resume function by simply reactivat-
ing it.
