A MESSAGE FROM FCA US LLC
FCA US LLC welcomes you as a turbocharged diesel-
powered truck owner. Your diesel truck will sound, feel,
drive, and operate differently from a gasoline-powered
truck. 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 ve-
hicle’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, com-
monly 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 System.
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 its factory settings.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained techni-
cians and genuine MOPAR® parts, and cares about your
satisfaction.
