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.

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.

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.

Vehicle Loading/Towing
Information
*
[DR29450(ALL)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.
[DR29504(ALL)08/95]
RWARNING
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these areas
are more likely to be seriously injured or
killed.

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]

242 [RE23625(ALL)06/95]8. Put the tire, jack, and wrench away. Make
sure jack is securely fastened so it doesn't
rattle when you drive. The carrier is
designed to hold the temporary spare which
comes with your vehicle. The stowage of a
full size tire in the spare tire carrier may
damage the tire or the vehicle. The flat full
size tire should be stowed securely in the
vehicle until it can be repaired.

[SV26100(ALL)05/95]
At least once a month, check the pressure in all
your vehicle's tires, including the spare. Use an
accurate tire pressure gauge. Check the tire
pressure when tires are cold, after the vehicle
has been parked for at least one hour or has
been driven less than 3 miles (5 km). You can
find proper cold pressure and load limits of
recommended size tires on the Safety
Compliance Certification Label.

Tire Inspection and Maintenance
*
[SV26300(ALL)02/95]
Inspect the tire treads, and remove stones, nails,
glass or other objects that may be wedged in the
tread grooves. Check for holes or cuts that may
permit air to leak from the tire, and make the
necessary repairs.
*
[SV26400(ALL)10/89]
Inspect the tire side walls for cuts, bruises and
other damage. If you suspect internal damage to
the tire, have it demounted and checked. You
may need to repair or replace it.

Tire rotation pattern
*
[SV26900(ALL)10/89]
After each rotation, adjust individual tire
pressure as specified on the Safety Compliance
Certification Label. Tighten wheel lug nuts to the
required torque specification and retighten again
after 500 miles (800 km).
*
[SV27000(ALL)08/95]
If your vehicle has aluminum wheels, you may
demount the full size, non-temporary spare
tire (if so equipped) and remount on an
aluminum wheel to rotate the spare tire into
your vehicle's rotation pattern. Rebalance the
wheel.
*
[SV27100(ALL)03/95]
You may discover uneven outside shoulder wear
on your vehicle's front radial tires if you drive
often in the city and turn frequently around
curbs. You can extend the life of your front tires
by remounting them so the outside of the tire
faces inside on the wheel rim.

Replacing the Tires
*
[SV27400(ALL)05/95]
Replace any tires that show wear bands. When
your tire shows a wear band, it has only 1/16
inch (2 mm) of tread left.
*
[SV27500(ALL)10/89]
quarter page art:0060006-A
Wear band
*
[SV27600(ALL)01/95]
Because your vehicle's tires may wear unevenly,
you may need to replace them before a wear
band appears across the entire tread. Some spots
wear more heavily than others.
*
[SV27700(ALL)03/90]
Your wheels and tires are match-mounted for
improved ride. Before you begin to repair a tire,
mark the wheel and tire so that they are
properly aligned when remounted. This will
ensure that the tires will continue to give you
the same ride level.
*
[SV27851(ALL)01/95]
RWARNING
When replacing full size tires, never mix
radial, bias-belted, or bias-type tires. Use
only the tire sizes that are listed on the
tire pressure decal. Make sure that all tires
are the same size, speed rating, and
load-carrying capacity. Use only the tire
combinations recommended on the decal.
If you do not follow these precautions,
your vehicle may not drive properly and
safely.
