[DR27675( ALL)06/92]
Never attempt to cross water that is fast flowing
or of unknown depth.
*
[DR27701( ALL)05/90]
Do not drive through flooded areas unless you
are sure that the water is below the bottom of
the wheel hubs.
*
[DR27750( ALL)04/94]
If you must drive through high water, drive
slowly. You may have limited traction or wet
brakes, so allow extra stopping distance because
your vehicle will not stop as quickly as usual.
*
[DR27801( ALL)01/95]
After you drive through the standing water,
apply your brakes gently several times as your
vehicle moves slowly. This helps to dry the
brakes.

NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.

NOTE: All rear axle lube quantities must be
replaced every 100,000 miles
(160,000 km) or if the axle has been
submerged in water. Otherwise, the
lube should not be checked or changed
unless a leak is suspected or repair
required.

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.

220Overloading a vehicle punishes components and
can lead to shortened service life or outright
failure.
*
[DR31001( ALL)06/92]
The capacity of the tires is included as part of
the axle and suspension system, which is to be
considered when determining the lowest rated
component. Tires are rated to carry a specific
maximum load at a specific maximum tire
pressure.
*
[DR31050( ALL)06/92]
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

Trailer Brakes
*
[DR38100( ALL)03/95]
Separate trailer brakes are required on most
towed vehicles weighing over 1,500 lb (680 kg).
*
[DR38200( ALL)05/95]
RWARNING
Do not connect a trailer's hydraulic brake
system directly to your vehicle's brake
system. Your vehicle may not have
enough braking power and your chances
of having a collision greatly increase.
*
[DR38300( ALL)01/93]
Trailer Lamps
*
[DR38400( ALL)11/89]
Make sure your trailer lamps conform to Federal
and local regulations.
[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.

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]
q
Apply the foot service brakes and hold.
*
[DR40100( ALL)11/89]
q
Have another person place the wheel chocks
under the trailer wheels.

service brakes, making sure the chocks are
holding.

parking brake by pressing the service brake
pedal down firmly with your right foot while
applying the parking brake pedal with your
left foot.

terminals.) Most jumper cables have a red
cable and a black cable. The red cable is
generally used for the positive terminals and
the black for the negative ones.
