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.

To operate in DRIVE (D) (Automatic mode):
•Press and hold the brake pedal.
• Move the shift lever to the DRIVE (D) position.
NOTE: If the vehicle is moving, DRIVE engagement will
only occur if the vehicle speed is less than 2 mph
(3 km/h). Otherwise, a chime will sound, the transmis-
sion will shift to NEUTRAL, and the DRIVE request must
then be repeated by returning the lever to NEUTRAL and
then back into DRIVE once the speed has been suffi-
ciently reduced.
• To drive, release the brake pedal and press the accel-
erator pedal.
When in DRIVE (D) the transmission will shift gears
automatically, the Automated Manual Transmission uses a geartrain and clutch similar to a other manual trans-
missions. Therefore, you should become familiar with
some of the normal operational characteristics of the
Automated Manual Transmission:
•
Engine torque will be interrupted briefly during the
transmission upshifts, making these shifts more abrupt
than with a typical automatic transmission. This is
normal.
• Although transmission shifting is performed auto-
matically, the vehicle will not creepwhen the brake
pedal is released, and may in fact roll down on an
incline. Leaving from a stop, the accelerator pedal
must be pressed to transmit driving torque to the
wheels.
• In Automatic Mode, the Automated Manual Transmis-
sion adapts the gear changing strategy evaluating the
road condition such as slopes in the road.

•To avoid accelerated clutch wear, do not use the
accelerator to keep the vehicle at a standstill (for
example, holding on a hill); the clutch could be dam-
aged by overheating. Use the brake pedal instead and
operate the accelerator only when you are ready to
drive away.
• Only launch (from a stop) in second gear when you
need more control on surfaces with low traction.
• Only shift between DRIVE (D) and REVERSE (R) gears
when the vehicle has come to a stop and the brake
pedal is pressed. •
Although very inadvisable, if the vehicle is unexpect-
edly allowed to roll downhill with the gearbox in
NEUTRAL (N) the system will automatically engage
the gear best suited to vehicle speed when a gear shift
is requested to allow drive to be correctly transmitted
to the wheels.
• If necessary, with the engine off, it is possible to engage
1st, REVERSE (R) or NEUTRAL (N) with the key in
ON/RUN/MAR position and the brake pressed.
• During hill starts, accelerate immediately after releas-
ing the parking brake or brake pedal to allow the
engine to increase its rpm to a greater extent and
overcome higher gradients with more torque.

The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for system
messages and warnings.
NOTE:
•Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal
operation.
• The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation and may be audible from under the
vehicle.TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
