WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel path is
clear. Make sure the liftgate is closed and latched
before driving away.NOTE:
•If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically
reverse to the closed or open position, provided it
meets sufficient resistance.
•There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips
will cause the liftgate to return to the open position.
•The power liftgate must be in the full open position in
order to power close. If the liftgate is not fully open,
press the RKE transmitter or overhead console button
to fully open the liftgate and then press again to close.
•If the liftgate handle is pulled while the power liftgate
is closing, the liftgate will reverse to the full open
position.

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller
•Side Remote Acceleration Sensors
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Window Bags above Side Windows
•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 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
detect a roll over when equipped with side airbags.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not “on” and will not inflate.
During a moderate-to-severe rear impact the ORC may
deploy the seat belt pretensioners alone.

•TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions or in a roll over
event. When the ORC (with side impact option) de-
tects a collision or roll over requiring the window bags
to inflate, it signals the inflators on the crash side of the
vehicle. Both window bags will inflate in a roll over
event. A quantity of nontoxic gas is generated to inflate
the window bag. The inflating window bag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time 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 window bag inflates.
This especially applies to children. The window bag is
only about 3-1/2 in (9 cm) thick when it is inflated.NOTE:At no time should any Supplemental Restraint
System (SRS) component or SRS-related component or
fastener be modified or replaced with any part except
those which are approved by the manufacturer/Mopar.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the impact sensors detect a moderate-to-severe
frontal collision, to help restrain the driver and front
passenger, and then immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.

Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
•The Airbag Warning Light does not come on or flickers
during the 6 to 8 seconds when the ignition switch is
first turned ON.
•The light remains on or flickers after the 2.5 to 8 sec-
onds interval.
•The light flickers or comes on and remains on 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 “Fuse Block” in Section 7.
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 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).

Automatic Headlights — If Equipped
Automatic headlights can be activated by rotating the
rotary headlight switch to the symbol “A.” The head-
lights will turn on when the engine is running and the
ambient light sensor indicates that the headlights should
be activated. The headlights will turn off if the headlight
switch is rotated to the off position or 90 seconds after the
ignition is turned OFF.
Headlight Delay
To aid in your exit, your vehicle is equipped with a
headlight delay that will leave the headlights on for
90 seconds. This delay is initiated when the ignition iscycled OFF while the headlight switch is on, and then the
headlight switch is cycled off. The headlights will remain
on for 90 seconds. Headlight delay can be canceled by
either turning the headlight switch on then off or by
turning the ignition ON.
The headlight delay time is programmable on vehicles
equipped with the Electronic Vehicle Information Center
(EVIC). For details, refer to “Personal Settings
(Customer-Programmable Features)” under “Overhead
Console with Electronic Vehicle Information Center
(EVIC) – If Equipped” in Section 3.

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.
REAR PARK ASSIST — IF EQUIPPED
The Rear Park Assist provides visible and audible indi-
cations of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist will remember the last system state
(enabled or disabled) from the last ignition cycle when
the ignition is changed to the ON position.The Rear Park Assist can be active only when the shift
lever is in REVERSE. If the Rear Park Assist is enabled at
this shift lever position, the system will be active until the
vehicle speed is increased to approximately 11 mph
(18 km/h) or above. The system will be active again if the
vehicle speed is decreased to speeds less than approxi-
mately 10 mph (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors field of view.
The sensors can detect obstacles from approximately 12
to 79 in (30 to 200 cm) from the rear fascia in the
horizontal direction, depending on the location, type and
orientation of the obstacle.

WARNING!
•Drivers must be careful when backing up, even
when using the Rear Park Assist. Always check
carefully behind your vehicle, look behind you,
and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.
(Continued)
WARNING! (Continued)
•Before using the Rear Park Assist, it is strongly
recommended that the ball mount and hitch ball
assembly is disconnected from the vehicle when
the vehicle is not used for towing. Failure to do so
can result in injury or damage to vehicles or
obstacles because the hitch ball will be much
closer to the obstacle than the rear fascia when the
warning display turns the red LEDs ON. Also, the
sensors could detect the ball mount and hitch ball
assembly, depending on its size and shape, giving
a false indication that an obstacle is behind the
vehicle.
