A MESSAGE FROM FCA US LLC
FCA US LLC welcomes you as a turbocharged diesel-
powered vehicle owner. Your diesel vehicle will sound,
feel, drive and operate differently from a gasoline-
powered vehicle. It is important that you read and
understand this manual.
Almost 100% of the heavy trucks in the United States and
Canada are diesel-powered because of the fuel economy,
rugged durability, and high torque which permits pulling
heavy loads.
You may find that some of the starting, operating, and
maintenance procedures are different. However, they are
simple to follow and careful adherence to them will
ensure that you take full advantage of the features of this
engine.NOTE:
•
Some aftermarket products may cause severe engine/
transmission and/or exhaust system damage. Your
vehicle’s powertrain control systems can detect and
store information about vehicle modifications that
increase horsepower and torque output such as
whether or not performance-enhancing powertrain
components, commonly referred to as downloaders,
power boxes, or performance chips have been used.
• Any chassis/suspension or tire size modifications to
the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning Sys-
tem.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed.
This information can be retrieved by FCA US LLC, and
service and repair facilities, when servicing your vehicle.

This information may be used to determine if repair will
be covered by New Vehicle Limited Warranty.
There is a probability that the use of a “performance
chip” will prohibit the engine from starting. In this
instance, the vehicle will need to be serviced by a
authorized dealer in order to return the vehicle to it’s
factory settings.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained tech-
nicians and genuine MOPAR® parts, and cares about
your satisfaction.

ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
•Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods.
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indica-
tors.
• Check the coolant and oil levels frequently.
• Vary accelerator pedal position at highway speeds
when carrying or towing significant weight. NOTE:
Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.

1. Speedometer•Indicates vehicle speed.
2. Electronic Vehicle Information Center (EVIC) •When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center
(EVIC) messages. Refer to “Electronic Vehicle Infor-
mation Center” in “Understanding Your Instrument
Panel” for further information.
• Odometer/Trip Odometer Display Area
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven. If
your odometer needs to be repaired or serviced, the
repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero,
and a sticker must be placed in the door jamb stating
what the mileage was before the repair or service. It is a good idea for you to make a record of the odometer
reading before the repair/service, so that you can be
sure that it is properly reset, or that the door jamb
sticker is accurate if the odometer must be reset at zero.

Shift Lever Status (PRND)
The shift lever status “P,R,N,D,1,2,3,4,5,6” are dis-
played indicating the shift lever position. Telltales
“1,2,3,4,5,6” indicate the manual mode has been
engaged and the gear selected is displayed. Refer to
“Six-Speed Automatic Transmission” in “Starting
And Operating” for further information on ERS.
3. Tachometer •This gauge measures engine revolutions per minute
(RPM x 1000). Before the pointer reaches the red area,
ease up on the accelerator to prevent engine damage.

4. Temperature Gauge•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up moun-
tain grades. It should not be allowed to exceed the
upper limits of the normal operating range.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
5. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
WARNING AND INDICATOR LIGHTS
IMPORTANT: The warning light switches on in the
instrument panel together with a dedicated message
and/or acoustic signal when applicable. These indica-
tions are indicative and precautionary and as such must
not be considered as exhaustive and/or alternative to the
information contained in the Owner Manual, which you
are advised to read carefully in all cases. Always refer to
the information in this chapter in the event of a failure
indication.

Charging System Warning Light
Red Telltale LightWhat It Means
Charging System Warning Light
This light shows the status of the electrical charging system. The light should come on
when the ignition switch is first turned to ON/RUN and remain on briefly as a bulb check.
If the light stays on or comes on while driving, turn off some of the vehicle’s nonessential
electrical devices or increase engine speed (if at idle). If the charging system light remains
on, it means that the vehicle is experiencing a problem with the charging system. Obtain
SERVICE IMMEDIATELY. See an authorized dealer.
If jump starting is required, refer to “Jump Starting Procedures” in “What To Do In Emergencies.”
