FLUIDS, LUBRICANTS AND GENUINE PARTS
Engine
Component Fluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use MOPAR® Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT(Organic Additive Technology).
Engine Oil Only use ACEA C3 5W-30 Synthetic Low Ash engine oil meeting FCA US Material Standard
MS-11106 or Pennzoil Ultra Euro L full synthetic 5W-30 motor oil.
Engine Oil Filter We recommend you use MOPAR® Engine Oil Filters.
Fuel Filters We recommend you use MOPAR® Fuel Filter. Must meet 3 micron rating. Using a fuel filter
that does not meet the manufacturers filtration and water separating requirements can
severely impact fuel system life and reliability.

Component Fluid, Lubricant, or Genuine Part
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requiresthat you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm Sulfur
maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15 will
provide good performance. We recommend you use a blend of up to 5% biodiesel, meeting
ASTM specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel
blends greater than 5% but no greater than 20% biodiesel meeting ASTM specification
D-7467 provided the shortened maintenance intervals are followed as directed.
Diesel Exhaust
Fluid MOPAR® Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API
Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO 22241 may result
in system damage.
124 MAINTAINING YOUR VEHICLE

NOTE:If the vehicle is exposed to extreme cold (below
20°F or -7°C), or is required to operate at colder-than-
normal conditions for prolonged periods, use climatized
No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50%
No. 1 diesel fuel. This will provide better protection from
fuel gelling or wax-plugging of the fuel filter.
CAUTION!
• Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) en-
gine coolant (antifreeze) or any “globally compat-
ible” coolant (antifreeze). If a non-OAT engine
(Continued)
CAUTION! (Continued)
coolant (antifreeze) is introduced into the cooling
system in an emergency, the cooling system will
need to be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032), by an au-
thorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (an-
tifreeze) is not recommended.

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)” or “Driver Information Dis-
play (DID)” 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 and power steering, and fill as needed
• Check function of all interior and exterior lights
128 MAINTENANCE SCHEDULE

Required Maintenance
Refer to the Maintenance Schedules on the following
pages for required maintenance.
At Every Oil Change Interval As Indicated By OilChange Indicator System:
•Change oil and filter.
• Completely fill the Diesel Exhaust Fluid tank.
• Drain water from fuel filter assembly.
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Inspect engine cooling system protection and
hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.

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.
140 INTRODUCTION

•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 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.
