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.
4 INTRODUCTION

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.
8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
16. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part
of an Onboard Diagnostic (OBD) system which
monitors the emissions and engine control sys-
tem. If the bulb does not come on during
starting, have the condition investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

19. Electronic Throttle Control (ETC) LightThis light informs you of a problem with
engine torque (or power) generation. If a prob-
lem is detected, the light will come on while the
engine is running. Cycle the ignition key when
the vehicle has completely stopped. The light should turn
off. If the light remains lit with the engine running, your
vehicle will usually be drivable (although performance
will be limited), see an authorized dealer for service as
soon as possible. If the light is flashing when the engine
is running, immediate service is required and you may
experience reduced performance, an elevated/rough idle
or engine stall and your vehicle may require towing. The
light will come on when the ignition is first turned to
ON/RUN and remain on briefly as a bulb check. If the
light does not come on during starting, have the system
checked by an authorized dealer. 20. TOW/HAUL — If Equipped
This light will illuminate when TOW HAUL
mode is selected.
21. Low Fuel Light
When the fuel level reaches approximately 3.0 gal (11.7
L), this light will turn on, and remain on until fuel is
added.
22. Fuel Gauge/Fuel Door Reminder When the ignition switch is in the ON/RUN
position, the pointer will show the level of fuel
remaining in the fuel tank. The fuel pump
symbol points to the side of the vehicle where
the fuel door is located.

23. Generic Warning LightThe Generic Warning Light will illuminate in
blinking mode if any of the following condi-
tions occur:
• Air Bag Warning Light Fault
• Engine Oil Pressure Sensor Failure
• Parking Sensor Failure
• Water In Fuel Presence
• Fuel Cutoff Intervention
• “Engine Minimum Oil Level”
• “Engine Min Oil Sensor Fail”
• Swivel Seat Malfunction
If the Generic Warning Light is blinking an air bag system
failure may be present, see an authorized dealer as soon
as possible. 24. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
25. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
4
UNDERSTANDING YOUR INSTRUMENT PANEL 25

vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction strategy to indicate when the system is not
operating properly. When the system detects a malfunc-
tion, the low tire pressure telltale will flash for approxi-
mately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the low tire pressure telltale is illuminated, the system
may not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS telltale after replacing one or more tires or wheels
on your vehicle, to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to continue to
function properly.

CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Diesel Exhaust Fluid (DEF) Messages
•First low level warning will be given at around 500
miles, which is determined by current consumption
rate. DEF Low level lamp icon and display message for
refill will be displayed at dashboard. DEF Low level
Lamp will stay on until a DEF refill is detected
(minimum 1 gallon).
• To correct, this condition it will be necessary to fully
refill the DEF tank.
• If refill is not performed, a second low level warning
will be given about 200 miles are left to empty the DEF
Tank. •
Display message of speed limitation with DEF Low
Level lamp will be there on dashboard.
• The driver will be informed about the speed restriction
also when about 150 and 125 miles are left to empty the
DEF Tank.
• When 100 miles are left to empty, the DEF Tank, a
continuous message display with chimes will be there
on dashboard.
• When count down is over (0 mile left), continuous
message Speed limited at refuel or next engine start 
is shown on EVIC. In this case, if an engine restart or
a diesel refuel action in engine-on condition is per-
formed, vehicle’s speed will be limited to 5 mph and
continuous message Speed limited DEF low is shown
on EVIC.

STARTING PROCEDURES
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 10-second
intervals. Waiting a few minutes between such intervals
will protect the starter from overheating.
WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
(Continued)
WARNING! (Continued)
•Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children). A child could
operate power windows, other controls, or move
the vehicle.
NOTE: Engine start up in very low ambient temperature
could result in evident white smoke. This condition will
disappear as the engine warms up.
CAUTION!
If the “Generic Warning Light” remains on and a
“Service Fuel Filter” message displays, DO NOT
START engine before you drain the water from the
fuel filter housing to avoid engine damage. Please
see your authorized dealer for draining the fuel
filter/water separator and fuel filter replacement.
