[TO05500(F )01/96]
A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs higher than when it's
warmed up. These faster engine speeds will
make your vehicle move slightly faster than its

142normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.
*
[TO05600(FM)01/96]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.
*
[TO05700(FM)01/96]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.
*
[TO05800(FM)01/96]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[TO05900(F )01/96]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[TO06000(F )01/96]
Engine Block Heater (If equipped)
*
[TO06100(F )01/96]
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10ÊF (-23ÊC) orbelow. An engine block heater
warms the engine coolant, which improves
starting, warms up the engine faster, and allows
the heater-defrost system to respond quickly.
*
[TO06200(F )01/96]
RWARNING
To prevent electrical shock, do not use
your heater with ungrounded electrical
systems or two-pronged (cheater) adapters.

*
[TO06300(F )01/96]
For best results, plug the heater in at least three
hours before you start your vehicle. Using the
heater for longer than three hours will not
damage the engine, so you can plug it in at
night to start your vehicle the following
morning.
*
[TO06400(F )01/96]
NOTE: Be sure to disconnect the engine block
heater before driving your vehicle.
*
[TO06500(FM)12/95]
Guarding Against Exhaust Fumes
*
[TO06600(FM)01/96]
Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
*
[TO06700(FM)02/96]
RWARNING
Do not start your vehicle in a closed
garage or in other enclosed areas. Exhaust
fumes can be toxic. Always open the
garage door before you start the engine.
*
[TO06800(FM)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.

Stopping Distances
*
[GF03450(FM)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.
%*
[GF03500(FM)01/96]
Applying the Brakes
*
[GF03550(FM)01/96]
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.
*
[GF03600(FM)01/96]
Do not drive with your foot resting on the brake
pedal. This will increase your vehicle's stopping
distance and may also cause brake damage.

150 [GF04300(F )05/96]When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.
*
[GF04350(F )05/96]
RWARNING
Do not leave the vehicle unattended with
the transfer case in the N (Neutral)
position. Always set the parking brake
fully and turn off the ignition when
leaving the vehicle.
[GF04400(FM)04/96]
To release the parking brake, press the service
brake pedal with your right foot and pull the
parking brake release lever.
*
[GF04500(FM)02/96]
RWARNING
If the parking brake is fully released, but
the Brake System light remains on, have
the brakes checked immediately. They
may not be working properly.
*
[GF04550(F )03/96]
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.

Steering Your Vehicle
%*
[GF05300(FM)01/96]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[GF05350(FM)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.
*
[GF05400(FM)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.
*
[GF05450(FM)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.
% [GF07425(F )04/96]Automatic Transmission
Operation (E4OD)
[GF07475(F )04/96]
The E4OD transmission is an electronically
controlled four speed automatic transmission
with overdrive. Transmission operation is
controlled by the Powertrain Control Module
(PCM).
[GF07525(FM)04/96]
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
File:09ltgff.ex

152Temperature 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 is first driven and has
not reached normal operating temperature.
[GF07550(FM)04/96]
The PCM also controls the transmission's Torque
Converter Clutch to further raise vehicle
performance and fuel economy. The Torque
Converter Clutch 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 after an upshift has
completed or when the driver has depressed the
throttle while driving at a steady road speed.
[GF07575(FM)01/96]
To help in troubleshooting, the PCM continually
performs self-tests on the electronic control
system and if any faults are detected, will store
them in memory. The Transmission Control
Indicator Light (TCIL), 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.
[GF07600(FM)01/96]
NOTE: The word ªOFFº located on the end of
the gearshift lever is the transmission
control indicator light (TCIL).

Putting Your Vehicle in Gear
[GF07650(FM)04/96]
Your vehicle's gearshift is on the steering
column. The Transmission Control Switch and
indicator light are located on the end of the
gearshift lever. You can put the gearshift in any
of the several positions.
