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

If brake failure is indicated, immediate repair
is necessary.
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.
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 re-
quired.
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.
