Priming If The Engine Has Run Out Of Fuel
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).
2. Turn ignition switch to the start position to engage starter for one second, return ignition switch to run
position. This will activate in tank fuel pump for ap-
proximately 15 seconds. Repeat this process twice.
3. Start the engine using the “Normal Starting” procedure. Refer to “Starting Procedures” in “Starting and Operat-
ing” for further information.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE: The engine may run rough until the air is forced
from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel blending agent.
They can be unstable under certain conditions and be
hazardous or explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the use
of these fuels can cause damage to the fuel system.
NOTE:
• A maximum blend of 5% biodiesel, meeting ASTM
specification D-975 may be used with your Cummins
diesel engine. (Chassis Cab models not configured with
B20 capability.)
188 MAINTAINING YOUR VEHICLE

•A maximum blend of 20% biodiesel, meeting ASTM
specification D-7467 may be used with your Cummins
diesel engine. (Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20% can negatively
impact the fuel filter’s ability to separate water from the
fuel, resulting in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your Cummins
diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of the
lowest emitting diesel engines ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust sys-
tem. The engine and exhaust after-treatment system work
together to achieve the EPA Heavy Duty Diesel Engine Emissions Standards. These systems are seamlessly inte-
grated into your vehicle and managed by the Cummins
Powertrain Control Module (PCM). The PCM manages
engine combustion to allow the exhaust system’s catalyst
to trap and burn Particulate Matter (PM) pollutants, with
no input or interaction on your part.
If the engine is allowed to idle or the truck is driven on low
engine speed drive cycles for more than 2 hours, the
system will automatically enter an emissions operating
mode that will increase the engine idle speed to 900 RPM
(1050 RPM for Chassis Cab). While in this mode, which is
designed to help maintain the diesel particulate filter, the
engine idle speed will return to normal when the brake
pedal is applied. A small change in engine tone or a slight
change in engine performance while accelerating may also
be noticeable at speeds below 20 mph (32 kmh). This
operating mode may last for up to an hour of idle time, or
around 20 minutes of driving time.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Instrument Cluster Display” in “Understanding
Your Instrument Panel” for further information.

Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that 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.
If climatized or diesel Number 1 ULSD fuel is not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions, Mopar Premium Diesel Fuel Treatment (or equiva-
lent) is recommended to avoid gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.Pickup models, and Chassis Cab models configured with optional B20
capability, are additionally compatible with 20% biodiesel meeting ASTM specification D-7467.
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. You can receive assistance in locating DEF in the United States by calling 866-RAM-
INFO (866-726-4636). In Canada call 1–800–465–2001 (English) or 1–800–387–9983 (French).
