Trailer frontal area considerations:
²Not to exceed towing vehicle frontal area without Class IV trailer
towing package
²Not to exceed 5.52 square meters (60 square feet) with Class IV
trailer towing package
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle's bumper or attach to the
axle. You must distribute the load in your trailer so that 10%±15% of the
total weight of the trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
Driving
179

If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Understanding the positions of the 4±speed automatic
transmissionsection in this chapter.
²Anticipate stops and brake gradually.
²Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
²Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.

Regular Cab and Super Cab (not available or recommended for
SuperCrew), and includes the following upgrades:
²F±150 4x4 (except F±150 SuperCrew)
²5.4L engine
²Heavy-duty payload package
²Snowplow prep package
Installing the snowplow
Weight limits and guidelines for selecting and installing the snowplow can
be found in the Ford Truck Body Builders Layout Book, Snowplow
section, found at www.fleet.ford.com/truckbbas. A typical installation
affects the following:
²Certification to government safety laws such as occupant protection
and air bag deployment, braking, and lighting. Look for an9Alterer's
Label9on the vehicle from the snowplow installer certifying that the
installation meets all applicable Federal Motor Vehicle Safety
Standards (FMVSS).
²The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle's Safety Certification Label. 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
²Rear 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.
²Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the Ford Workshop
Manual.
²Headlight aim may require re-adjustment.
²The 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

Operating the vehicle with the snowplow attached
Ford recommends that the F±150 be limited to low speed, personal-use
snow removal. Do not use your vehicle for snow removal until it has
been driven at least 800 km (500 miles).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature:
²If you are driving more than 24 km (15 miles) where outside air
temperatures are above freezing, then angle the plow blade to full left
or right to maximize airflow to the radiator.
²If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather you will not need to adjust blade position
Snowplowing with your air bag equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag (SRS) is
provided.
Never remove or defeat the ªtripping mechanismsº designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
Transmission operation while plowing
²Shift transfer case to 4L (4WD Low) when plowing in small areas at
speeds below 8 km/h (5 mph).
²Shift transfer case to 4H (4WD High) when plowing larger areas or
light snow at higher speeds. Do not exceed 24 km/h (15 mph).
Driving
184

²Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
²If 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 few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Engine temperature while plowing
When driving with a plow, your engine may run at a higher temperature
than normal because the attached snowplow blade will restrict airflow to
the radiator.
If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
