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

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 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 tooverheat 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 indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem 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 malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause

sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
