Diesel Particulate Filter (DPF) Messages
This engine meets all required diesel engine emissions
standards. To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine and
exhaust system. These systems are seamlessly integrated
into your vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine combustion to
allow the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or inter-
action 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 into contact with your exhaust sys-
tem. 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 vehicle or engine. Refer to
the following messages that may be displayed on your
instrument cluster:
• Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy — This message will be displayed in
the instrument cluster 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 conditions re-
quired 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
in the Instrument Cluster Display. If this message is
displayed, you will hear one chime to assist in alerting

you of this condition. By simply driving your vehicle at
highway speeds for up to 20 minutes, you can remedy
the condition in the particulate filter system and allow
your diesel engine and exhaust after-treatment system to
cleanse the filter to remove the trapped PM and restore
the system to normal operating condition.
• Exhaust System — Regeneration In Process Exhaust
Filter XX% Full — 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 Service Required — See Dealer Now — This
messages indicates regeneration 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 display a MIL light.CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
• Exhaust Filter Full — Power Reduced See Dealer —
This message indicates the PCM has derated the engine
to limit the likelihood of permanent damage to the
after-treatment system. If this condition is not corrected
and a dealer service is not performed, extensive exhaust
after-treatment damage can occur. To correct this condi-
tion it will be necessary to have your vehicle serviced by
your local authorized dealer.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Displays
When the appropriate conditions exist, the Instrument
Cluster Display displays the following messages:
• System Setup Unavailable – Vehicle Not in Park
• System Setup Unavailable – Vehicle in Motion

5. After engine start-up, check to see that there is oilpressure.
6. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger at
low coolant temperatures to improve engine warm-up.
• The engine may not automatically crank after the engine
Wait To Start telltale goes off if a door or the hood is
ajar.
• If the engine stalls, or if the ignition switch is left ON for
more than two minutes after the “Wait To Start Light”
goes out, reset the grid heaters by turning the ignition
switch to the OFF position for at least five seconds and
then back ON. Repeat steps 1 through 7 of “Keyless
Enter-N-Go Starting Procedure – Engine Manifold Air
Temperature Below 66° F (19° C).”Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and op-
eration:
• The engine block heater is a resistance heater installed in
the water jacket of the engine just above and behind the
oil filter. It requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer.
• A 12 Volt heater built into the fuel filter housings aid in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A heated intake air system both improves engine start-
ing and reduces the amount of white smoke generated
by a warming engine.

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 into contact with your exhaust sys-
tem. Do not park or operate your vehicle in areas where
your exhaust system can contact anything that can
burn.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key compo-
nent of selective catalytic reduction (SCR) systems, which
help diesel vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with engine
exhaust in the presence of a catalyst to convert smog-
forming nitrogen oxides (NOx) into harmless nitrogen and
water vapor.
Refer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
You can receive assistance in locating DEF in the United
States by calling 866-RAM-INFO (866-726-4636). In Canada
call 1–800–465–2001 (English) or 1–800–387–9983 (French)
Maintenance-Free Batteries
The top of the maintenance-free batteries are permanently
sealed. You will never have to add water, nor is periodic
maintenance required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
CAUTION!
It is essential when replacing the cables on the battery
that the positive cable is attached to the positive post
and the negative cable is attached to the negative post.
Battery posts are marked (+) positive and negative (-)
and are identified on the battery case. Also, if a “fast
charger” is used while the battery is in vehicle, discon-
nect both vehicle battery cables before connecting the
charger to the battery. Do not use a “fast charger” to
provide starting voltage.
