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.)

If you are experiencing an ªengine cut-outº
condition at high speeds, it may be the result of
this limiting device. It is a normal condition and
can be avoided by reducing vehicle/engine
speed.

Automatic Transmission
Operation (4R44E/4R55E)
*
[DR00350(ALL)08/95]
The 4R44E and 4R55E transmissions are
electronically controlled four speed overdrive
automatic transmissions with lockup torque
converter. Transmission operation is controlled
by the Powertrain Control Module (PCM).
*
[DR00425(ALL)08/95]
The PCM will automatically adjust transmission
operation to make up for varying conditions.
Several sensors located on the engine and
transmission such as throttle position, engine
speed, vehicle speed and transmission
temperature are used by the PCM to shift the
transmission into a higher or lower gear when
required for the best performance and fuel
economy. For example, you may notice that the
transmission will upshift to a higher gear more
quickly when the vehicle has not reached normal
operating temperature.
*
[DR00475(ALL)08/95]
The PCM also controls the transmission's Torque
Converter Clutch (TCC) to further raise vehicle
performance and fuel economy. The TCC will
engage when the transmission operating
temperature and other conditions determined by
the PCM have been met. Engagement of the
clutch may be noted as a decrease in engine
speed.
[DR00500(ALL)08/95]
To help in troubleshooting, the PCM continually
performs self-tests on the electronic control
system and, if any faults are detected, stores
them in memory. The Overdrive Off Indicator
Light (O/D OFF), which is located on the

malfunction has been detected. If the Overdrive
Off Indicator Light is flashing, contact your Ford
dealer as soon as possible. If this condition
persists, damage to the transmission could occur.
*
[DR00700(ALL)03/95]
Some vehicles are equipped with a Powertrain
Control Module that limits engine speeds with a

When to usej(Overdrive)
[DR06800(ALL)08/95]
This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third and fourth gears will occur when
jOverdrive is chosen on the selector and the
transmission control switch has not been
pressed. The transmission will shift into the
correct gear when the right speed is achieved,
for the accelerator pedal position you have
chosen.
[DR06810(ALL)08/95]
When to use Drive
[DR06830(ALL)08/95]
You will note there is not a drive position on
your gearshift indicator. However, you will find
a transmission control switch labeled
OVERDRIVE OFF located on the end of the
gearshift lever. Press this switch and the
indicator light (OFF) illuminates on the gearshift
lever. With overdrive cancelled and the word
OFF illuminated, the transmission will operate in
gears one through three. This is useful if you
experience frequent downshift/upshift
conditions, when operating with a heavy load or
in hilly terrain, or if additional engine braking is

Steering Your Vehicle
%*
[DR15945(ALL)01/95]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[DR15950(ALL)04/95]
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.
*
[DR15960(ALL)01/95]
Never hold the steering wheel to the extreme
right or left for more than five seconds if the
engine is running. This can damage the power
steering pump.
*
[DR15985(ALL)05/90]
NOTE: After any severe impact such as
striking large potholes, sliding into
curbs on icy roads, or a collision
involving the front end, observe the
steering wheel alignment. If the spokes
of the steering wheel seem to be in a
different position while going straight
down the road, have the front
suspension and steering checked for
possible damage.
[DR16005(ALL)06/95]Electronic 4-Wheel Drive (E-4WD)
(If equipped)
[DR16015(ALL)06/95]
If your vehicle is equipped with the E-4WD
option, power is provided to all four wheels
whenever you press the accelerator pedal. It
improves both handling and traction during
difficult driving conditions, adjusting
automatically to your driving needs. Because the
entire E-4WD system is controlled by a
microprocessor, your vehicle is not equipped
with the switch or shift lever used with most
traditional 4WD vehicles. The microprocessor
does all the adjusting for you.

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.

Stopping Distances
*
[DR24100(ALL)11/89]
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.
%*
[DR24200(ALL)01/95]
Applying the Brakes
*
[DR24300(ALL)05/95]
Apply the brake pedal gradually. Use the
ªsqueezeº technique Ð push on the brake pedal
with a steadily increasing force. This allows the
wheels to continue to roll while you are slowing
down, which lets you steer properly.
*
[DR24500(ALL)05/95]
NOTE: If you are driving down a long or
steep hill, shift to a lower gear and do
not apply your brakes continuously. If
you apply your brakes continuously,
they may overheat and become less
effective.
