The power point can switch to a fault mode when it is overloaded,
overheated, or shorted. Unplug your device and turn the ignition off then
on for overloading and shorting conditions. Let the system cool off, then
turn the ignition off then on for an overheating condition.
The power point can provide power whenever the ignition is on and the
indicator light is on. The indicator light is located in the top left corner
of the power point.
When the indicator light is:
•on — power point is ready to supply power
•off — power point power supply is off; ignition is not on
•blinking — power point is in fault mode.

•The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Compliance Certification Label. This
applies to Ford-completed vehicles of 10,000 pounds (4,536 kilograms)
GVWR or less. This is the weight of permanently-attached auxiliary
equipment, such as snowplow frame-mounting hardware, that can be
added to the vehicle and satisfy Ford compliance certification to
FMVSS. Exceeding this weight may require the auxiliary equipment
installer additional safety certification responsibility. The Front
Accessory Reserve Capacity (FARC) is added for customer
convenience.
•Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
•Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the FordWorkshop
Manual.
•Headlight aim may require re-adjustment.
•The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.
Operating the Vehicle with the Snowplow Attached
Note:Do not use your vehicle for snow removal until it has been driven
at least 500 miles (800 kilometers).
Ford recommends vehicle speed does not exceed 45 mph (72 km/h)
when snowplowing.
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature: Attention to engine
temperature is especially important when outside temperatures are
above freezing. Angle the blade to maximize airflow to the radiator and
monitor engine temperature to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in yourscheduled maintenance
informationfor engine oil and transmission fluid change intervals.

Transmission operation while plowing
WARNING:Do not spin the wheels at over 35 mph (55 km/h).
The tires may fail and injure a passenger or bystander.
•Shift transfer case to4L(4WD Low) when plowing in small areas at
speeds below 5 mph (8 km/h).
•Shift transfer case to4H(4WD High) when plowing larger areas or
light snow at higher speeds. Do not exceed 15 mph (24 km/h).
•Do not shift the transmission from a forward gear toR(Reverse) until
the engine is at idle and the wheels are stopped.
•If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a minute. The transmission and tires may be damaged or the
engine can overheat.
Outside Air Temperature While Plowing
The outside air temperature reading can be inaccurate while plowing
with your vehicle due to the sensor air flow being blocked by the plow
blade.
A Ford Wiring Kit (XXXX-XXXXX-XX) is available to relocated the OAT
sensor to the plow blade frame below the headlamp to provide accurate
outside air temperature readings.
VEHICLE USED AS A STATIONARY POWER SOURCE
Auxiliary equipment called power take-off, or PTO, is often added to the
engine or transmission to operate utility equipment. Examples include a
wheel-lift for tow trucks, cranes, tools for construction or tire service,
and pumping fluids. PTO applications draw auxiliary horsepower from
the powertrain, often while the vehicle is stationary. In this condition,
there is limited cooling air flow through the radiator and around the
vehicle that normally occurs when a vehicle is moving. The aftermarket
PTO system installer, having the most knowledge of the final application,
is responsible for determining whether additional chassis heat protection
or powertrain cooling is required, and alerting the user to the safe and
proper operation.
Ford Super Duty Vehicles are approved for use as a stationary (including
split shaft capability) or mobile power source, within limits and operating
guidelines detailed in theFord Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas, and through the Ford Truck
Body Builders Advisory Service.

UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches will only operate
while the ignition is in the on
position, whether the engine is
running or not. However, it is
recommended that the engine
remain running to maintain battery charge when using the upfitter
switches for extended duration or higher current draws. (This is even
more important for vehicles with diesel engines since the glow plugs are
also draining battery power when the ignition key is in the on position.)
When switched on, they provide 8 amps, 12 amps or 20 amps of
electrical battery power for a variety of personal or commercial uses.
There will also be a relay box located on the driver side end of the
instrument panel. See your authorized dealer for service.
