cluster display will flash to show proper oper -
ation of the front and rear turn signal lights.
NOTE:
If either light remains on and does not
flash, or there is a very fast flash rate,
check for a defective LED turn signal in
the headlamp. Please see an authorized
dealer for service.
When the Daytime Running Lights are on
and a turn signal is activated, the Daytime
Running Lamp will turn off on the side of
the vehicle in which the turn signal is
flashing. The Daytime Running Lamp will
turn back on when the turn signal is
turned off.
Automatic Headlight Leveling — HID
Headlights Only
This feature prevents the headlights from
interfering with the vision of oncoming
drivers. Headlight leveling automatically
adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.
Battery Saver
To protect the life of your vehicle’s battery,
load shedding is provided for both the inte -
rior and exterior lights.
If the ignition is OFF and any door is left ajar
for 10 minutes or the dimmer control is
rotated all the way up to the dome on posi -
tion for 10 minutes, the interior lights will
automatically turn off. NOTE:
Battery saver mode is canceled if the ignition
is ON.
If the headlights remain on while the ignition
is placed in the OFF position, the exterior
lights will automatically turn off after eight
minutes. If the headlights are turned on and
left on for eight minutes while the ignition is
OFF, the exterior lights will automatically
turn off.
NOTE:
The battery saver mode is canceled if the
ignition is OFF and the headlamp switch is in
the park lamp position. The parking lamps
will remain on and drain the vehicle's
battery.

If anything obstructs the Hands-Free Lift-
gate while it is opening or closing, the lift -
gate will automatically reverse to the
closed/open position, provided it meets
sufficient resistance.
There are pinch sensors attached to the
side of the liftgate opening. Light pressure
anywhere along these strips will cause the
liftgate to return to the open position.
If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop. If this
occurs, the liftgate must be operated
manually.
The power liftgate will release, but not
power open, in temperatures below −12°F
(−24°C). Be sure to remove any buildup of
snow or ice from the liftgate before
opening the liftgate.
If the liftgate is left open for an extended
period of time, the liftgate may need to be
closed manually to reset power liftgate
functionality. Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary
to assist the props when opening the liftgate
in cold weather.
NOTE:
Allow the power system to open the liftgate.
Manually pushing or pulling the liftgate may
activate the liftgate obstacle detection
feature and stop the power operation or
reverse its direction.
INTERNAL EQUIPMENT
Power Outlets
Your vehicle is equipped with 12 Volt (13
Amp) power outlets that can be used to
power cellular phones, small electronics, and
other low powered electrical accessories. The
power outlets are labeled with either a “key”
or a “battery” symbol to indicate how the
outlet is powered. Power outlets labeled with
a “key” are powered when the ignition switch
is in the ON or ACC position, while the
outlets labeled with a “battery” are
connected directly to the battery and
powered at all times.
NOTE:
All accessories connected to the “battery”
powered outlets should be removed or turned
off when the vehicle is not in use to protect
the battery against discharge.
WARNING!
Driving with the liftgate open can allow
poisonous exhaust gases into your
vehicle. You and your passengers could
be injured by these fumes. Keep the lift
-
gate closed when you are operating the
vehicle.
If you are required to drive with the lift -
gate open, make sure that all windows
are closed, and the climate control
blower switch is set at high speed. Do
not use the recirculation mode.
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.

The front power outlet is located inside the
storage area in front of the shifter.Front Power OutletPower Inverter — If Equipped
Rear Center Console Power Inverter
There is a 230 Volt (150 Watt) inverter outlet
located on the back of the center console to
convert DC current to AC current. This outlet
can power cellular phones, electronics and
other low power devices requiring power up
to 150 Watts. Certain high-end game
consoles exceed this power limit, as will
most power tools.
To turn on the power inverter outlet, simply
plug in the device. The outlet automatically
turns off when the device is unplugged.
WARNING!
To avoid serious injury or death:
Only devices designed for use in this
type of outlet should be inserted into any
12 Volt outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery,
even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in
long enough, the vehicle's battery will
discharge sufficiently to degrade battery
life and/or prevent the engine from
starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.)
will degrade the battery even more
quickly. Only use these intermittently
and with greater caution.
After the use of high power draw acces-
sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
generator to recharge the vehicle's
battery.

If brake failure is indicated, immediate
repair is necessary.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is
required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi -
nate, have the light inspected by an autho -
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position. NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
— Battery Charge Warning Light

This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Contact
an authorized dealer as soon as possible.

This indicates a possible problem with the
electrical system or a related component.
— Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Electric Power Steering Fault Warning
Light

This warning light will turn on when there's a
fault with the EPS (Electric Power Steering)
system. Refer to “Power Steering” in “Starting And Operating” in the Owner’s Manual for
further information.

— Electronic Throttle Control (ETC)
Warning Light
This warning light will illuminate to indicate
a problem with the Electronic Throttle
Control (ETC) system. If a problem is
detected while the vehicle is running, the
light will either stay on or flash depending on
the nature of the problem. Cycle the ignition
when the vehicle is safely and completely
stopped and the transmission is placed in
the PARK (P) position. The light should turn
off. If the light remains on with the vehicle
running, your vehicle will usually be drive -
able; however, see an authorized dealer for
service as soon as possible.
NOTE:
This light may turn on if the accelerator and
brake pedals are pressed at the same time.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.

Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal
circuits and interconnecting wiring associ-
ated with the electrical Air Bag System
Components. Your vehicle may be equipped
with the following Air Bag System Compo -
nents:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag
system whenever the ignition
switch is in the START or ON/RUN position.
If the ignition switch is in the OFF position or
in the ACC position, the air bag system is not
on and the air bags will not inflate. The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC
detects a malfunction in any part of the
system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound to alert you if the
light comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system
immediately.
Failure to replace the seat belt assembly
could increase the risk of injury in
collisions.
Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or
forward-facing child restraints that have
a harness for restraining the child.
WARNING! (Continued)

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may
occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and
unfold. The abrasions are similar to fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem-
icals. 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 air bags 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 air
bag 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 irri -
tation, move to fresh air. If the irritation
continues, see your doctor. If these parti -
cles settle on your clothing, follow the
garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you. NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
After any collision, the vehicle should be
taken to an authorized dealer immedi
-
ately.
Enhanced Accident Response System
In the event of an impact, if the communica -
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the Occupant Restraint Controller
(ORC) will determine whether to have the
Enhanced Accident Response System
perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor
(if equipped)
Flash hazard lights as long as the battery
has power
Turn on the interior lights, which remain
on as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in
another collision. Have the air bags, seat
belt pretensioners, and the seat belt
retractor assemblies replaced by an
authorized dealer immediately. Also, have
the Occupant Restraint Controller System
serviced as well.

Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.

Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the
starter from overheating.NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke.
This condition will disappear as the engine
warms up.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera -
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable
battery blankets are available from your
authorized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel telltales when
starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP
button once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
WARNING!
Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously or
fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN
mode. A child could operate power
windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before
repeating start procedure.
