Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.

[IS05100( ALL)01/96]
The light comes on briefly when you turn the
ignition key toON, but it should turn off when
the engine starts. If the light does not come on
when you turn the ignition toONor if it comes
on and stays on when you are driving, have
your vehicle serviced as soon as possible. This
indicates a possible problem with one of the
vehicle's emission control systems. You do not
need to have your vehicle towed in.
*
[IS05200( ALL)01/96]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
*
[IS05300( ALL)01/96]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.
*
[IS05500( ALL)01/96]
An example of a condition which corrects itself
occurs when an engine running out of fuel
begins to misfire. In this case, the Check Engine
Warning Light may turn on and will then set a
Diagnostic Trouble Code indicating that the
engine was misfiring while the last of the fuel
was being consumed. After refueling, the Check
Engine Warning Light will turn off after the
vehicle has completed three consecutive warm

A warm up cycle consists of engine start from a
cold condition (engine at ambient temperature)
and running until the engine reaches normal
operating temperature.
*
[IS05600( ALL)01/96]
On the fourth engine start up, the Check Engine
Warning Light will turn off as soon as the
engine begins to crank. It is not necessary to
have the engine serviced.

[IS05700( ALL)01/96]
Under certain conditions, the Check Engine
Warning Light may come on if the fuel cap is
not properly installed. If the Check Engine
Warning Light comes on and you suspect that
the fuel cap is not properly installed, pull off the
road as soon as it is safely possible and turn off
the engine. Remove and replace the fuel cap,
making sure it is properly seated.
*
[IS05800( ALL)01/96]
After completing the three consecutive warm up
cycles and on the fourth engine start up, the
Check Engine Warning Light should turn off. If
the light does not go off after the fourth engine
restart, have your vehicle serviced by your
dealer or a qualified technician.

[IS09400( M)01/96]
For a proper fuel gauge indication after adding
fuel, the ignition switch should be in the OFF

NOTE: If your speed increases above your set
speed while driving inj(Overdrive)
on a downhill grade, you may want to
depress the transmission control switch
located on the shift lever to turn off
overdrive to reduce vehicle speed.
Speed control cannot reduce the vehicle
speed if it goes above your set speed
on a downhill grade. For the best fuel
economy during normal driving
conditions, leave the shift select inj

RWARNING
Do not use the speed control in heavy
traffic or on roads that are winding,
slippery, or unpaved.

In mountainous areas, at higher elevations, or
when pulling a trailer, the speed control may

To maintain a preset speed under the above
conditions, with electronically controlled

Climate conditions and other factors play a large
part in deciding how you should go about
starting your vehicle. Read all the starting
instructions carefully, so you'll be aware of these
factors when you start your vehicle.
[TO00600( M)01/96]
When starting a fuel-injected engine,the most
important thing to remember is to avoid
pressing down on the accelerator before or
during starting.SeeStarting Your Enginein this

accelerator while you start your vehicle.

If the engine still does not start, the fuel pump
shut-off switch may have been triggered. For
directions on how to reset the switch seeFuel

[TO05400( M)01/96]
NOTE: When turning the ignition key from
the ªOFFº to the ªRUNº position, a
subtle humming may be heard for up
to three seconds. This is the normal
sound of an electronically controlled
fuel pump, and indicates the operation
or pre-pressurizing the EFI system for
starting.

[TO05600( ALL)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.

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.

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.

The Base Curb Weight is the weight of the
vehicle including fuel, coolants, lubricants,
emergency tools, spare wheel and tire. It also
includes any equipment that isstandardon that
model. It does not include passengers, cargo or
optional equipment installed by factory, dealer,
aftermarket supplier or customer.

Payload
*
[GF20980( ALL)01/96]
Payload is the combined, maximum allowable

is Gross Vehicle Weight Rating minus the base
curb weight.

Gross Vehicle Weight (GVW)
*
[GF21000( ALL)01/96]
If you add base curb weight and the weight of a
load (including passengers, cargo and optional
equipment) being carried at a particular time,
you get the Gross Vehicle Weight (GVW).
*
[GF21010( ALL)01/96]
It is important to remember that GVWis not a
limit or a specification.If an owner loads up a
vehicle and weighs it, that's the GVW at that
moment. If the owner piles on more of a load
and weighs it again, that becomes the GVW.

Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[GF21110( ALL)01/96]
With the tires inflated to the specified pressure
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.

[GF21120( ALL)01/96]
GCWR (Gross Combined Weight Rating)
*
[GF21130( ALL)01/96]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[GF21140( ALL)01/96]
Maximum Trailer Weight Rating
*
[GF21150( ALL)01/96]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It is specified by the
manufacturer and is determined by subtracting
the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight
of the driver from the GCWR for the towing
vehicle.

[GF21160( ALL)01/96]
Maximum Trailer Weight
*
[GF21170( ALL)01/96]
The maximum trailer weight is the maximum
weight of a trailer the loaded vehicle is
permitted to tow. It is determined by subtracting
the weight of the loaded towing
vehicle (including passengers and cargo) from
the GCWR for the towing vehicle.
