The red warning light for the brakes can show
three things Ð that either the parking brake is
not fully released, that the brake fluid level is
low in the master cylinder reservoir or the
vacuum pressure is low on diesel engine
vehicles. If the fluid level is low, the brake
system should be checked by a qualified service
technician.
*
[LG03400( ALL)05/94]
This light comes on when you turn the ignition
key to START to verify that the indicator bulb is
working. If the light stays on or comes on after

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.
*
[LG04600( ALL)05/95]
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.
*
[LG04625( ALL)05/95]
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.
*
[LG04650( ALL)05/95]
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.

[LG04662( F )05/95]
NOTE: If your light truck is equipped with
dual fuel tanks, the ªCHECK ENGINEº
light may come on if fuel is restricted
to the engine or if the fuel flow is
momentarily disrupted because of an
empty fuel tank before you switched to
the auxiliary fuel tank. This condition
is normal and the light should go off
after full fuel flow is restored.
*
[LG04675( ALL)05/95]
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
up cycles without a misfire condition occurring.
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.
*
[LG04700( ALL)05/95]
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.
*
[LG04725( ALL)05/95]
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.

Engine Oil Pressure Gauge
*
[LG07601( ALL)06/93]
This gauge indicates the engine's oil pressure,
not the oil level. However, if your engine's oil
level is low, it could affect the oil pressure. With
the engine running, the pointer should move
into the NORMAL band. If the pointer drops
below the NORMAL band while the engine is
running, you have lost oil pressure and
continued operation will cause severe engine
damage.
*
[LG07701( ALL)03/95]
If you lose engine oil pressure:
*
[LG07801( ALL)01/95]
1. Pull off the road as soon as safely possible.
*
[LG07901( ALL)04/95]
2. Shut off the engine immediately or severe
engine damage could result.
*
[LG08001( ALL)02/95]
3. Check the engine's oil level, following the
instructions on checking and adding engine
oil. Refer toEngine oilin the Index. If you
do not follow these instructions, you or
others could be injured. To assure an
accurate reading, your vehicle should be on
level ground.
*
[LG08051( ALL)03/93]
4. If the level is low, add only as much oil as
necessary before you start the engine again.
Do not overfill. Do not operate the engine if
the pointer is below the NORMAL band,
regardless of the oil level. Contact your
nearest dealer for further service actions.

Speedometer
*
[LG12700( ALL)01/95]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[LG12750(BEF )04/95]
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. NOTE: The conversion constant can
only be changedsix timesonce the vehicle
leaves the factory. Your Ford dealership service
personnel can change the conversion constant.
*
[LG12753(BEF )01/95]
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).

When you come to a stop, do not downshift
through each gear. Disengage the clutch and use
the brake as necessary. Downshifting through
the gears decreases your vehicle's fuel economy.
*
[DR15400(B F )05/95]
RWARNING
Continued use of a damaged or worn
clutch, prolonged clutch slippage or
downshifting at excessive speeds can
result in a failure of the engine,
transmission or clutch components.

Transmission Function
*
[DR15600(B F )03/91]
Upshift at the speeds specified in the chart
available for your engine and transmission. All
forward gears are synchronized allowing you to
shift into them with your vehicle in motion. The
clutch pedal should be fully depressed when
shifting.
*
[DR15625(B F )04/94]
NOTE: Shifting during extremely low rpm's
can result in a momentary audible
rattle which disappears as vehicle
rpm's are increased. Shifting at higher
speeds will eliminate this sound.
*
[DR15700(B F )03/95]
Parking
*
[DR15800(B F )01/95]

Driving on Snow or Ice
*
[DR21200(B F )10/90]
A four-wheel drive vehicle has advantages over
two-wheel drive vehicles in snow and ice but
can skid like any other vehicle. If so equipped,
keep the vehicle in four-wheel drive if icy or
slippery conditions exist.
*
[DR21300(B F )11/89]
Avoid sudden applications of power and quick
changes of direction on snow or ice. Apply the
accelerator slowly and steadily when starting
from a full stop.
[DR21312(B F )05/95]
All utility-type and Four-Wheel Drive vehicles
have special design and equipment features to
make them capable of performing in a wide
variety of off-road applications. Specific design
characteristics give them higher centers of
gravity than ordinary passenger cars.
*
[DR21325(B F )05/95]
RWARNING
All utility and four-wheel drive vehicles
are not designed for cornering at speeds
as high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns or abrupt
maneuvers in these vehicles.
