A MESSAGE FROM FCA US LLC
FCA US LLC and Cummins welcome you as a Cummins
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 duty trucks in the United
States and Canada are diesel-powered because of the fuel
economy, rugged durability, and high torque which per-
mits pulling heavy loads. Cummins engines power well
over half of these trucks. Now this same technology and
proven performance is yours in your truck equipped
with the Cummins turbocharged diesel engine.
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.
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 the 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.

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
• The Remote Start system will wait for the “Wait To
Start” telltale to extinguish before cranking the engine.
This allows time for the intake heater to pre-heat the
incoming air, and is normal operation in cold weather.
Refer to “Wait To Start” in “Understanding Your
Instrument Panel”.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Transmission in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Ignition key removed from ignition switch
• Battery at an acceptable charge level
• RKE PANIC button not pushed
• Fuel meets minimum requirement
• Water In Fuel Indicator Light is not illuminated
138 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Remote Start Comfort Systems — If Equipped
When remote start is activated, the heated steering
wheel, and driver heated seat features will automatically
turn on in cold weather. In warm weather, the driver
vented seat feature will automatically turn on when the
remote start is activated. These features will stay on
through the duration of remote start or until the ignition
switch is turned to the ON position.
The Remote Start Comfort System can be activated and
deactivated through the EVIC/DID. For more informa-
tion on Remote Start Comfort System operation refer to
your Owners Manual.
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins turbocharged diesel engine does not re-
quire a break-in period due to its construction. Normal
operation is allowed, providing the following recommen-
dations 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 throttle position at highway speeds when carry-
ing 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.

•If the button is continually pushed, the set speed will
continue to increase until the button is released, then
the new set speed will be established.
To Decrease Speed
When the Electronic Speed Control is set, you can de-
crease speed by pushing the SET (-) button.
The drivers preferred units can be selected through the
instrument panel settings if equipped. Refer to “Under-
standing Your Instrument Panel” for more information.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (-) button once will result ina1mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph. •
If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
