Do not tow a trailer until your vehicle has been
driven at least 500 miles (800 km).

Vehicle Loading/Towing
Information
*
[DR29450(BEF )03/91]
Your vehicle's load capacity is designated by
weight, not volume, so you cannot necessarily
use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire,
rim sizes and inflation pressures are specified for
your vehicle at the assembly plant on the Safety
Compliance Certification Label. The Certification
Label is located on the left front door lock facing
or the door latch post pillar.
*
[DR29501( ALL)12/91]
Trucks, unlike passenger cars, are basically
custom vehicles designed to carry a load. Most
owners start with a base vehicle and add
production and dealer installed and/or
aftermarket components to suit their tastes and
purposes. Even trucks that are purchased for
personal transportation only are likely to have
considerable optional equipment, such as step
bumpers and light bars, for example.
*
[DR29525( ALL)05/95]
RWARNING
Passengers should not be allowed to ride
in the cargo area. Persons not riding in a
seat with a fastened seat belt are much
more likely to suffer serious injury in a
collision. Cargo should always be secured
to prevent it from shifting and causing
damage to the vehicle or harm to
passengers.
*
[DR29551( ALL)03/91]
Each additional item of equipment affects how
much cargo a vehicle can carry. If a vehicle is
overloaded, performance will suffer and service
concerns may arise.

Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[DR31101(BEF )07/92]
The vehicle must not be loaded to both the front
and rear GAWR because the GVWR will be
exceeded. The GAWR of the front and rear axles
exceed the GVWR when added together to allow
flexibility in fore and aft loading of cargo.
*
[DR31110( ALL)06/92]
With the tires inflated to the specified pressure
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[DR31120( ALL)06/92]
GCWR (Gross Combined Weight Rating)
*
[DR31130( ALL)06/92]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[DR31140( ALL)06/92]
Maximum Trailer Weight Rating
*
[DR31150( ALL)06/92]
The maximum weight of a trailer the vehicle is
permitted to tow. The maximum trailer weight
rating is specified by the manufacturer and is
determined by subtracting the vehicle curb
weight for each engine/transmission
combination, any required option weight for
trailer towing and the weight of the driver from
the GCWR for the towing vehicle.

244 [DR38417(B F )05/95]Your vehicle has been equipped for use with a
4-wire trailer tow electrical system (running
lamps, right hand stop/turn, left hand
stop/turn, and ground).
*
[DR38425(BEF )03/91]
Class I and Class II Trailer Tow electrical wiring
provides two circuits (right hand and left hand)
to operate trailer stop/turn tail lamps. Each
stop/turn circuit will operate one combination
stop/turn light bulb (# 1157, 3157, 2357, or 3357)
on the trailer. Never add more than one trailer
light bulb to one circuit.
[DR38429(B F )05/95]
A wire harness (Ford part number
F5TB-13A576-A) has been provided that connects
to the frame wire harness at the rear of the
vehicle and is compatible with most 4-wire
trailer tow electrical systems.
[DR38431(B F )05/95]
Always check trailer and vehicle functions (i.e.,
stop/turn signal, and running lights) before
operating your vehicle and trailer.
[DR38433(B F )05/95]
If your vehicle fails to function properly, do not
operate your vehicle and trailer until corrections
are made.
*
[DR38450( ALL)05/95]
RWARNING
Always replace a fuse with one that has
the specified amperage rating. Using a
fuse with a higher amperage rating can
cause severe wire damage and could start
a fire.

Driving while you tow
*
[DR38520( ALL)05/95]
Be especially careful when driving while you
tow a trailer. Never drive faster than 45 mph
(70 km/h) when you tow in hilly country on
hot days. Also, anticipate stops so that you can
brake gradually.

Trailer towing tips
*
[DR39100( ALL)11/89]
Before starting on a trip, practice turning,
stopping and backing in an area away from
heavy traffic. Get to know the ªfeelº of the
vehicle/trailer combination.
*
[DR39200( ALL)05/90]
Practice backing up. Back up very slowly, with
someone outside at the rear of your trailer to
guide you. Place your hand at the bottom of the
steering wheel and move it in the direction you
want the rear of the trailer to swing. Slight
movement of the steering wheel results in a
much larger movement of the rear of the trailer.

[DR39300( ALL)11/89]
Allow more room for stopping with a trailer
attached. Trailer brakes should be applied first,
whether manually or automatically controlled,
when approaching a stop.
*
[DR39400( ALL)11/89]
For a good handling truck-trailer combination,
the trailer tongue load should be approximately
10-15% of the loaded trailer weight.
*
[DR39500( ALL)05/95]
Make a thorough check of your equipment
before starting out on the road. After you have
traveled about 50 miles (80 km) stop in a
protected area and double-check your hitch and
electrical connections. Also check trailer wheel
lug nuts for tightness.
*
[DR39600( ALL)11/89]
When turning, drive slightly beyond the normal
turning point so the trailer wheels will clear
curbs or other obstructions.
*
[DR39725(B F )03/95]
When stopped in traffic for long periods of time
in hot weather, place the gearshift selector lever
in P (Park) to increase the engine idle speed.
This aids in engine cooling and air conditioner
efficiency. If the engine overheats, move the
function selector knob to VENT to stop the
compressor and increase the engine speed for a
short time.
*
[DR39900( ALL)05/90]
Vehicles with trailers should not be parked on a
grade. However, if you must park on a grade,
place wheel chocks under the trailer's wheels as
follows:
*
[DR40000( ALL)11/89]

Vehicle Operation On the Road
*
[DR42400( F )01/93]
When operating on the road, your engine may
run at a temperature higher than normal because
the attached snowplow blade will restrict airflow
to the radiator. So if you are driving more than
15 continuous miles (24 km), at temperatures
above freezing, angle the plow blade either full
left or full right to provide maximum airflow to
the radiator. Shorter trips of 15 miles (24 km) in
cold weather may be made at speeds up to
40 mph (64 km/h) without paying special
attention to plow blade position.
*
[DR42500( F )01/93]
Vehicle Operation While Plowing
*
[DR42600( F )01/93]
Guard against transmission and drivetrain
damage. When plowing small areas or heavy
snow, operate with the transfer case in 4L and a
vehicle speed of 0-5 mph (8 km/h). When
plowing larger areas or light snow, at higher
speeds, operate with the transfer case in 4H and
do not exceed 15 mph (24 km/h).
*
[DR42700( F )01/93]
Do not shift the transmission from forward to
reverse until the engine is at idle and the wheels
are stopped.
