MAINTAINING YOUR VEHICLE 125
Page 130 of 360

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage
•Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
•Check function of all interior and exterior lights

A MESSAGE FROM FCA US LLC
FCA US LLC and Cummins® welcome you as a Cum-
mins® turbocharged diesel-powered truck owner. Your
diesel truck will sound, feel, drive, and operate differ-
ently 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.

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 “Electronic Vehicle Information Center/EVICWarning Lights” in “Understanding Your Instrument
Panel” for further information on and “Wait To Start”
telltale and pre-heat cycle.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•HAZARD switch off
•BRAKE switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed
146 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 152 of 360
•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.For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting And Operating” of the
Owners Manual.
Because of the construction of the Cummins® turbo-
charged diesel engine, engine run-in is enhanced by
loaded operating conditions which allow the engine
parts to achieve final finish and fit during the first 6,000
miles (10 000 km).

The Transmission Gear Position Indicator is self-
contained within the instrument cluster. It displays the
gear range of the automatic transmission.NOTE:The highest available transmission gear is dis-
played in the lower right corner of the Electronic Vehicle
Information Center (EVIC) whenever the Electronic
Range Select (ERS) feature is active. Use the +/- selector
on the shift lever to activate ERS. Refer to “Automatic
Transmission” in “Starting And Operating” for further
information.
