RWARNING
When parking, do not use the gearshift in
place of the parking brake. Turn the key
to LOCK whenever you leave your
vehicle. Always set the parking brake
fully and make sure that the gearshift is
securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual
transmission). Never leave your vehicle
unattended while it is running. If you do
not take these precautions, your vehicle
may move unexpectedly and injure
someone.
[DR24970(B F )05/95]

[DR25100( ALL)01/95]
The parking brake is not designed to stop a
moving vehicle, but you can use the parking
brake to stop your vehicle in an emergency if
the normal brakes fail. However, since the
parking brake applies only the rear brakes, the
stopping distance will increase greatly and the
handling of your vehicle will be adversely
affected.

Tips for Safe Driving
*
[DR25301( ALL)05/95]
As with any new vehicle, yours may drive and
handle differently from your previous vehicle.
Use care until you become accustomed to its
various features and driving characteristics.
*
[DR25350( ALL)03/95]
Operate your vehicle within reasonable limits.
Sudden acceleration, deceleration, turning, or
combinations of these maneuvers can cause a
vehicle to behave differently than anticipated.

RWARNING
To avoid losing control on slippery roads,
do not downshift into Low with the
automatic transmission when moving
faster than 20 mph (32 km/h). Do not
downshift into First with the manual
transmission when moving faster than
5 mph (8 km/h).
*
[DR27350(B F )06/94]
RWARNING
The rear antilock brake system may not
prevent brake lock-up on extremely
slippery surfaces. Rear brake lock-up may
also occur while driving in four-wheel
drive because the transfer case couples the
front and rear axles together.
*
[DR27450(BEF )03/95]
Traction-Lok Rear Axle (If equipped)
*
[DR27501(BEF )03/95]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.
*
[DR27550(BEF )03/93]
Extended use of other than matching size tires
on a Traction-Lok rear axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.
*
[DR27601(BEF )05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

passenger or bystander.
*
[DR28050(BEF )03/95]
Driving With a Heavy Load
*
[DR28101(BEF )01/95]
There are limits to the amount of weight your
vehicle can carry or tow. The total weight of
your vehicle, plus the weight of the passengers
and cargo, should never be more than the Gross
Vehicle Weight Rating (GVWR). Also, the weight
that your vehicle carries over the front axle and
rear axle should never be more than the Gross
Axle Weight Rating (GAWR) for the respective
axle.
*
[DR28150(BEF )01/95]
The weight limits of your vehicle's tires affect
the GVWR or GAWR limitations. Usage of
replacement tires with higher weight limit than
originals does not increase GVWR or GAWR.
Usage of lower capacity replacement tires may
lower GVWR and GAWR limitations.
*
[DR28201(BEF )02/95]
RWARNING
If the GVWR or the GAWR specified on
the Safety Compliance Certification Label
is exceeded, your vehicle may be damaged
or you may lose control and injure
someone.

[DR29401( ALL)06/92]
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.

224passengers to all seating positions, and add
evenly distributed cargo in the box without
exceeding the GAWR F.
*
[DR31950( ALL)06/92]
It is possible to hang heavier equipment on the
front as long as the vehicle owner/operator
compensates. This can be accomplished, if
necessary, by carrying fewer passengers, less
cargo or positioning cargo more toward the rear,
which has the effect of reducing the load on the
front. Keep in mind that the GAWR F, GAWR
R, nor the GVWR should ever be exceeded.
*
[DR32001( ALL)05/91]
Total Accessory Reserve Capacity in Pounds:
On the sample label this value is given as 112
pounds (51 kgs). This is a number that is related
to government crash test standards, and only
indirectly reflects on the amount of accessory
weight that can be carried.
*
[DR32050( ALL)06/94]
In the case of both these numbers (83 and 112
pounds) (38 and 51 kgs), the important thing to
remember is that for safe operation, an
owner/operator should calculate the amount and
the distribution of all weights (passengers,
accessory equipment and cargo). These combined
weights should fall below the vehicle's GVWR
and GAWR.
*
[DR32201( ALL)01/93]
Trailers
*
[DR32251( ALL)10/94]
Towing a trailer safely means having the proper
weight on the tongue (usually 10% of the trailer
weight). Load-equalizing hitches on large rigs
may transfer weight to each of the vehicle's
axles. This weight must be included in capacity
calculations when determining if the vehicle is
loaded within safe limits.
*
[DR32301( ALL)01/95]
If your vehicle exceeds the GVWR, remove cargo
from your vehicle accordingly. If your vehicle
exceeds the GAWR for either axle, shift the load
or remove cargo accordingly.

*
[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.

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
