Speedometer
*
[LG12700(ALL)01/95]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[LG12750(ALL)08/95]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when
the tires are changed will also ensure that the
speedometer retains the original factory-set
accuracy.
[LG12752(ALL)08/95]
NOTE: The conversion constant can only be
changed six times once the vehicle
leaves the factory. Your Ford dealership
service personnel can change the
conversion constant.
*
[LG12753(ALL)08/95]
Some vehicles are equipped with a vehicle speed
(mph/km/h) limiting device that is contained
within the Powertrain Control Module (PCM).
The purpose of this device is to maintain peak
vehicle speed below a specified limit. (Vehicle
speed limits may vary based on engine
displacement.)

192 [DR16025(ALL)05/94]How the Electronic 4-Wheel Drive (E-4WD)
System Works
[DR16036(ALL)03/90]
Under normal driving conditions, when the road
is firm, dry and level, the engine power is
distributed one-third to the front axle and
two-thirds to the rear axle. However, if a wheel
begins to slip, the microprocessor will sense this
condition and signal the system to transmit more
power to the axle with more traction. (You may
feel a momentary surge of power.)
[DR16046(ALL)06/95]
NOTE: The microprocessor is disabled when
the brakes are applied or when the
transmission selector is in the P (Park)
or N (Neutral) positions.
[DR16055(ALL)05/94]
Driving Your Electronic 4-Wheel Drive
(E-4WD) Vehicle
[DR16065(ALL)03/95]
Since your E-4WD vehicle is unique, follow these
steps to be safe:
[DR16075(ALL)03/95]
q
Avoid unnecessary turns or other maneuvers
that could cause loss of control and possible
injury.
[DR16076(ALL)06/95]
q
Use the same size and type of tire and wheel
as originally provided for your vehicle and
inflate the tires to the manufacturer's
recommended air pressure.
[DR16077(ALL)03/95]
q
Become familiar with your vehicle's operating
characteristics and study this Owner Guide
for specific operating instructions. Be sure all
occupants wear the safety belts provided.
Drive cautiously, defensively, and at speeds
safe for current road conditions.

Traction-Lok Rear Axle (If equipped)
*
[DR27501(ALL)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(ALL)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.

[DR27651(ALL)01/95]
High water
*
[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.
*
[DR27820(ALL)06/95]
NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.
*
[DR27825(ALL)03/93]
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.

Rocking the vehicle
*
[DR27950(ALL)05/95]
If your vehicle gets stuck (for example, in mud
or snow), you may rock it out of the spot. Shift
in a steady rhythm between forward and reverse
gears. Allow the transmission to fully engage,
then press lightly on the accelerator. Do not rock
the vehicle for more than a few minutes. This
may overheat the engine and transmission,
causing damage to both. In addition, other
vehicle systems and components may also be
damaged.
*
[DR27975(ALL)05/95]
RWARNING
Do not spin the wheels at over 35 mph
(55 km/h). The tires may fail and injure a
passenger or bystander.

[DR28050(ALL)03/95]
Driving With a Heavy Load
*
[DR28101(ALL)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(ALL)08/95]
The weight limits of your vehicle's tires affect
the GVWR or GAWR limitations. Usage of
replacement tires with higher weight limits than
originals does not increase GVWR or GAWR.
Usage of lower capacity replacement tires may
lower GVWR and GAWR limitations.

[DR28201(ALL)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.
*
[DR28750(ALL)01/93]
Vehicle/Trailer Loads
*
[DR28801(ALL)06/92]
All vehicles may tow a Class I trailer provided
the Gross Combined Weight (GCW) is less than
or equal to the GVWR shown on the Safety
Compliance Certification Label. For heavier
trailer applications, refer to the towing
information found later in this chapter.
*
[DR29001(ALL)03/91]
Towing a trailer puts additional loads on your
vehicle's engine, transmission, axle, brakes, tires
and suspension. For your safety and for the
good of your vehicle, use the right equipment
for the type of trailer you tow.
*
[DR29025(ALL)09/92]
Your trailer towing capability will vary based on
the standard and optional equipment on your
vehicle. Refer to the followingVehicle
Loading/Towing Informationand the Trailer
Towing Tables to determine the specific towing
capability of your vehicle.
*
[DR29050(ALL)02/92]
q
Stay within the load limits when you tow.
*
[DR29101(ALL)01/95]

Gross Vehicle Weight Rating (GVWR)
*
[DR30750(ALL)10/94]
To avoid overloading a vehicle, the owner
should observe the manufacturer's specified
Gross Vehicle Weight Rating. The GVWR is the
maximum total weight of base vehicle,
passengers, optional components and cargo that
a particular vehicle was designed to carry.
%*
[DR30801(ALL)01/93]
Gross Axle Weight Rating (GAWR)
*
[DR30850(ALL)03/91]
We have all seen a car or a truck that is loaded
down in the rear and riding high in the front.
This is a dangerous condition that usually means
that the rear suspension components are under
severe strain and that vehicle handling is
impaired. There is more to carrying a load than
just payload or GVWR.
*
[DR30901(ALL)03/91]
Your Safety Compliance Certification Label not
only gives the GVWR, it also gives the Gross
Axle Weight Rating (GAWR) which is the
carrying capacity for each axle system. For
trucks, the rear axle will be designed to carry
more weight than the front.
*
[DR30950(ALL)06/92]
The rating is based on the carrying capacity of
thelowest ratedaxle and suspension component
as well as other factors. This is why it's so
important to observe vehicle loading ratings.
Overloading 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(ALL)05/95]
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
exceeds 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)05/95]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It 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.

Changing a Tire
*
[RE03700(ALL)01/95]
If you get a flat tire while you are driving, do
not apply the brake heavily. Instead, gradually
decrease the speed. Hold the steering wheel
firmly and slowly move to a safe place on the
side of the road. Park on a level spot, turn off
the ignition, set the parking brake, and turn on
the hazard flashers.

The Conventional Spare Tire
*
[RE03900(ALL)01/95]
If you have the conventional spare tire, you can
use it as a spare or as a regular tire. This spare
tire is identical to the other tires that come with
your vehicle, although the wheel may not match.
%*
[RE04000(ALL)03/95]
The Temporary Spare Tire
*
[RE04100(ALL)03/95]
You may have a high pressure temporary spare
tire. This spare tire is smaller than a regular tire
and is designed for emergency use only. Use it
only when you get a flat tire and replace it as
soon as you can. This spare tire is marked with
the words ªTEMPORARY USE ONLYº so that
you can easily identify it.

If you use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing
you to lose control of the vehicle, possibly
injuring yourself or others.
[RE04250(ALL)05/95]
RWARNING
The tire size on the E-4WD must be
maintained.
[RE04260(ALL)06/95]
Your vehicle may have a full diameter mini
spare or a full size tire. This full diameter mini
spare is special for the E-4WD and another mini
spare from another vehicle can not be
substituted without the possibility of damage to
your vehicle. All tires should be inflated to the
manufacturer's recommended pressures.
*
[RE04275(ALL)05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.
*
[RE04280(ALL)10/94]
Extended use of other than matching size spare
tires on a Traction-Lok 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.
