Guarding Against Exhaust Fumes
*
[TO09400(ALL)01/96]
Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
*
[TO09600(ALL)01/96]
RWARNING
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes.
[TO09700(ALL)04/96]
If your vehicle has rear windows and doors that
were installed as part of a van conversion, close
them while it is running. This prevents exhaust
fumes from being drawn into the passenger
compartment.
*
[TO09900(ALL)01/96]
Have the exhaust and body ventilation systems
checked whenever:
*
[TO10000(ALL)01/96]
q
your vehicle is raised for service
*
[TO10100(ALL)01/96]
q

*
[TO10200(ALL)01/96]
q
your vehicle has been damaged in a collision
*
[TO10300(ALL)01/96]
Improve your ventilation by keeping all air inlet
vents clear of snow, leaves, and other debris.
*
[TO10400(ALL)01/96]
If the engine is idling while you are stopped in
an open area for long periods of time, open the
windows at least one inch (2.5 cm). Also, adjust
the heating or air conditioning system to bring
in outside air.
*
[TO10600(ALL)01/96]

[GF01150(ALL)01/96]
If during normal operation the brake pedal
seems ªlowº, it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
%*
[GF01200(ALL)01/96]
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes louder or more frequent, have your
brakes inspected by your dealer or a qualified
service technician.
*
[GF01250(ALL)03/96]
RWARNING
Modifications to the suspension spring
rates and/or vehicle ride height may
adversely affect vehicle stopping ability.
*
[GF01300(ALL)03/96]
If Brakes Pull
*
[GF01350(ALL)03/96]
q
Check tire pressure.
*
[GF01400(ALL)03/96]
q
Perform the self-adjustment procedure
described underIf Brakes Do Not Grip Well or
Pedal is ªLow.º
*
[GF01450(ALL)03/96]
If pull occurs during the first 500 miles
(800 km), make 10 moderately fast stops from
40 mph (65 km/h) and then perform the
self-adjustment procedure above. It may be
necessary to repeat this operation to properly
seat new brake linings and pads.

[GF01500(ALL)01/96]
Stopping Distances
*
[GF01550(ALL)01/96]
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.

[GF04000(ALL)01/96]
Steering Your Vehicle
%*
[GF04100(ALL)01/96]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[GF04150(ALL)03/96]
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.
*
[GF04200(ALL)01/96]
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.
*
[GF04300(ALL)01/96]
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.
[GF10000(ALL)03/96]Automatic Transmission
Operation (4R44E/5R55E)
[GF10050(ALL)06/96]
If your vehicle is equipped with an automatic
transmission, it will be either a four speed
overdrive transmission (4R44E) or a five speed
overdrive transmission (5R55E). All 3.0L engines
use the 4R44E transmission, while all 4.0L
engines use the 5R55E transmission. Both
transmission types have a lockup torque
converter. Transmission operation is controlled
by the Powertrain Control Module (PCM).
File:09cpgfa.ex
Update:Wed Jun 5 12:04:06 1996

169
*
[GF10150(ALL)01/96]
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.
*
[GF10200(ALL)01/96]
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.
[GF10250(ALL)05/96]
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 Transmission Control
Indicator Light (TCIL) (O/D OFF), which is
located on the gearshift lever, may flash steadily
if a malfunction has been detected. If the TCIL is
flashing, contact your Ford dealer as soon as
possible. If this condition persists, damage to the
transmission could occur.
*
[GF10320(ALL)05/96]
Speed limiter
*
[GF10330(ALL)06/96]
All models are equipped with a Powertrain
Control Module (PCM) which limits the
maximum engine speed and thus road speed in
top gear. Vehicle operation is normal since the
controlled maximum speed is above posted
highway speeds in North America.

Power Braking
*
[GF10410(ALL)05/96]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.
*
[GF10450(ALL)05/96]
NOTE: Continued operation in the stall
condition can result in transmission
overheat, malfunction or fluid
expulsion.

Putting Your Vehicle in Gear
[GF10800(ALL)05/96]
Your vehicle's gearshift is on the steering
column. The transmission control switch is
located on the end of the gearshift lever. You
can put the gearshift in any one of several
positions.

When to use Drive
[GF13250(ALL)01/96]
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
OVERDRIVE 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 useful. However,
shift back toj(Overdrive) whenever practical
for optimum powertrain cooling and fuel
economy. This can be accomplished by pushing
the transmission control switch again, to cancel
the OVERDRIVE OFF control and light.
[GF13300(ALL)06/96]

When to use 2 (Second)
*
[GF13450(ALL)05/96]
Use 2 (Second) to start-up on slippery roads or
to provide additional engine braking on
downgrades. This position provides 2 (Second)
gear operation only.
*
[GF13475(ALL)05/96]
When to use 1 (Low)
*
[GF14000(ALL)05/96]
Use 1 (Low) to provide maximum engine
braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) orj(Overdrive). Selection of 1 (Low)
gear provides only low gear operation from
start-up. Selection of 1 (Low) while at higher
speeds provides a shift to second gear, and a
shift to first gear will occur after the vehicle
decelerates to the proper speed.
*
[GF14500(ALL)05/96]
Forced Downshifts
[GF14550(ALL)03/96]
To gain acceleration inj(Overdrive) or Drive
(jposition with Overdrive cancelled) when
passing another vehicle, push the accelerator to
the floor. The transmission will downshift to the
appropriate gear: third, second or first.

[GF14650(ALL)05/96]
When to usej(Overdrive)
*
[GF14700(ALL)05/96]
This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third, fourth and fifth gears will occur
whenj(Overdrive) 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.

178 [GF16025(ALL)01/96]How the Electronic 4-Wheel Drive (E-4WD)
System Works
[GF16036(ALL)01/96]
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.)
[GF16046(ALL)01/96]
NOTE: The microprocessor is disabled when
the brakes are applied or when the
transmission selector is in the P (Park)
or N (Neutral) positions.
[GF16055(ALL)01/96]

(E-4WD) Vehicle
[GF16065(ALL)01/96]
Since your E-4WD vehicle is unique, follow these
steps to be safe:
[GF16075(ALL)01/96]
q
Avoid unnecessary turns or other maneuvers
that could cause loss of control and possible
injury.
[GF16076(ALL)01/96]
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.
[GF16077(ALL)01/96]
q
