Snow Plow Mode
Snow Plow Mode can be activated when the vehicle has
a snow plow installed. This mode fully engages the fan
clutch to increase the airflow when the plow is attached
to the vehicle.
NOTE:There may be an increase in fan noise and a
decrease in fuel economy may result when using this
feature. The fan clutch operation can be initiated by
performing the following button sequence.
1. Turn the ignition key to the on position or start the
vehicle.
2. Pull in the Cruise Control “Cancel” button/lever and
hold. While holding the Cruise Control “Cancel”, push
the “Exhaust Brake” button twice within five seconds.
Repeat this sequence four times. The chime will sound
twice as an audible indicator that the function is engaged. 3. To disable the function, repeat Step 2. The chime will
sound four times as an audible indicator that the function
is disengaged.
Operating Precautions
Avoid Overheating The Engine
The temperature of the engine coolant (antifreeze) (a
mixture of 50% ethylene-glycol and 50% water) must not
exceed the normal range of the temperature gauge 240°F
(116°C) with a 16 psi (110 kPa) radiator cap.
Usually the engine coolant (antifreeze) temperature indi-
cated during operation will be to the left of center in the
normal range of the gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low engine coolant (antifreeze)
temperature below the normal range on the gauge 140°F
(60°C) can be harmful to the engine. Low engine coolant

Fuel Specifications
The Cumminsdiesel engine has been developed to take
advantage of the high energy content and generally
lower cost No. 2 Ultra Low Sulfur diesel fuel or No. 2
Ultra Low Sulfur climatized diesel fuels. Experience has
shown that it also operates on No. 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.
NOTE:
•A maximum blend of 5% biodiesel meeting ASTM
specification D-6751 may be used with your Cum-
mins diesel engine.
•In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
minsdiesel engine.
•No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.
ADDING FUEL
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.

WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be burned.
Always place fuel containers on the ground while
filling.
Fuel Filler Cap
If the fuel filler cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap. A poorly fitting cap could let impuri-
ties into the fuel system.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the fuel filler cap is removed or
the tank filled.
•Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage – Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
