Driving uphill or on a steep grade
*
[CF35700( ALL)01/96]
When the speed control is on, your vehicle may
significantly drop speed when driving uphill,
especially with a heavy load. If the speed drops
more than 8 to 14 mph (15 - 25 km/h) the
automatic speed control will, by design, be
canceled. You may have to temporarily resume
manual speed control while driving up a steep
grade in order to maintain the speed you desire.
*
[CF35800( ALL)01/96]
Frequent shifting of an automatic transmission or
speed loss during speed control operation can be
eliminated by shifting out of overdrive into
drive (or by pressing the Transmission Control
Switch, if equipped). These conditions could
occur in hilly terrain or at higher elevations.

Checking Parking Brake and Transmission
Park Mechanism
[GF04700( M)01/96]
Periodically check the holding ability of the
parking brake by stopping on a steep hill and
restraining the vehicle by using only the parking
brake with the transmission in N (Neutral).
Check the holding ability of the P (Park)
mechanism (automatic transmissions) by
releasing all brakes after moving the

Steering Your Vehicle
%*
[GF05300( ALL)01/96]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[GF05350( ALL)01/96]
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( 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.
*
[GF05450( 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.

Automatic Transmission
Operation (E4OD)
[GF07500( M)01/96]
The E4OD transmission is an electronically
controlled four speed automatic transmission
with overdrive. Transmission operation is
controlled by the Powertrain Control Module
(PCM).
*
[GF07525( 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 is first driven and has
not reached normal operating temperature.
*
[GF07550( ALL)01/96]
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( ALL)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.

When to usej(Overdrive)
*
[GF08100( ALL)01/96]
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.

[GF08125( ALL)01/96]
When to use Drive
*
[GF08150( ALL)01/96]
You will note that there isn't a drive position on
your gearshift indicator. However, you will find
a Transmission Control Switch and an indicator
light labeled ªOverdriveº located on the end of
the gearshift lever. Press this switch and the
word ªOFFº will illuminate on the shift lever
knob. With the word ªOFFº illuminated, the
transmission will operate in gears one through
three. Operating in the Overdrive ªOFFº mode
gives more engine braking than Overdrive and
is useful for descending hills or when towing.

When starting your vehicle, the overdrive system
will automatically be in the normal overdrive
mode.
*
[GF08250( ALL)01/96]
If the Transmission Control Indicator Light is
flashing on and off steadily, a transmission
system malfunction was detected. The
transmission will operate in a failure
management mode and may have harsh
engagements, firm shift feel, or abnormal shift
schedule. If this condition persists, damage to
the transmission could occur. Contact your
dealer as soon as possible.
