gate must be opened or closed manually.
WARNING!
• Driving with the liftgate open can allow
poisonous exhaust gases into your ve-
hicle. You and your passengers could be
injured by these fumes. Keep the liftgate
closed when you are operating the
vehicle.
• If you are required to drive with the
liftgate open, make sure that all win-
dows are closed, and the climate control

CAUTION!
• Power outlets are designed for accessory
plugs only. Do not insert any other object
in the power outlets as this will damage
the outlet and blow the fuse. Improper
use of the power outlet can cause dam-
age not covered by your New Vehicle
Limited Warranty.
WARNING!
To avoid serious injury or death:
• Do not insert any objects into the
receptacles.
• Do not touch with wet hands.
• Close the lid when not in use.
• 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
alternator to recharge the vehicle's
battery.
• Power outlets are designed for accessory
plugs only. Do not hang any type of
accessory or accessory bracket from the
plug. Improper use of the power outlet
can cause damage.
ROOF LUGGAGE RACK — IF
EQUIPPED
The crossbars and siderails are designed to
carry the weight on vehicles equipped with a
luggage rack. The load must not exceed
150 lbs (68 kg), and should be uniformly
distributed over the luggage rack crossbars.
NOTE:
If not equipped with crossbars, your autho-
rized dealer can order and install Mopar
crossbars built specifically for this roof rack
system.
Distribute cargo weight evenly on the roof
rack crossbars. The roof rack does not in-
crease the total load carrying capacity of the
vehicle. Be sure the total load of cargo inside
the vehicle plus that on the external rack
does not exceed the maximum vehicle load
capacity.
To move the crossbars, loosen the attach-
ments, located at the upper edge of each
crossbar, approximately eight turns using the
anti-theft wrench provided with the Mopar
crossbars. Then, move the crossbar to the
desired position, keeping the crossbars par-

Diesel Particulate Filter (DPF) Messages
— If Equipped
This engine meets all required diesel engine
emissions standards. To achieve these emis-
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte-
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the ex-
haust system’s catalyst to trap and burn Par-
ticulate Matter (PM) pollutants, with no input
or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
WARNING!
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. Refer to the following mes-
sages that may be displayed on your instru-
ment cluster display:
•Exhaust Filter Nearing Full Safely Drive at
Highway Speeds to Clear— This message
will be displayed if the exhaust particulate
filter reaches 80% of its maximum storage
capacity. Under conditions of exclusive
short duration and low speed driving cycles,
your diesel engine and exhaust after-
treatment system may never reach the con-
ditions required to cleanse the filter to
remove the trapped PM. If this occurs, the
“Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy” message will
be displayed. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition. By simply driving yourvehicle at highway speeds for up to 20 min-
utes, you can remedy the condition in the
particulate filter system and allow your die-
sel engine and exhaust after-treatment sys-
tem to cleanse the filter to remove the
trapped PM and restore the system to nor-
mal operating condition.
•Exhaust System Regeneration in Process Con-
tinue Driving— This message indicates that
the Diesel Particulate Filter (DPF) is self-
cleaning. Maintain your current driving
condition until regeneration is completed.
•Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition.
•Exhaust System Service Required — See
Dealer— This messages indicates regen-
eration has been disabled due to a system
malfunction. At this point the engine Pow-
ertrain Control Module (PCM) will register a
fault code, the instrument panel will dis-
play a MIL light.
69

CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with con-
tinued operation.
•Exhaust Filter Full — Power Reduced See
Dealer— This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
damage can occur. To correct this condition
it will be necessary to have your vehicle
serviced by an authorized dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with con-
tinued operation.
Fuel System Messages — If Equipped
The following chart contains a list of different
messages that may appear in the instrument
cluster, depending on different system or fuel
conditions. Use the descriptions to interpret
what the message means and determine the

WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first
if applicable. The system check menu may
appear different based upon equipment op-
tions and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights
— Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four
to eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a
single chime when a fault with the air bag has
been detected, it will stay on until the fault is
cleared. If the light is either not on during
startup, stays on, or turns on while driving,
have the system inspected at an authorized
dealer as soon as possible.
— Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking
brake is applied, that the brake fluid level is
low, or that there is a problem with the
anti-lock brake system.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
