Check Engine Warning Light
*
[LG04550(ALL)05/95]
The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.
*
[LG04575(ALL)05/95]
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)07/95]
The light comes on briefly when you turn the
ignition key to the ON position, but it should
turn off when the engine starts. If the light does
not come on when you turn the ignition to ON
or 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.
[LG04650(ALL)08/95]
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.
[LG04700(ALL)08/95]
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.

79 [LG04750(ALL)08/95]
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 mifire 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.
[LG04825(ALL)07/95]
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.
[LG04875(ALL)07/95]
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 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.
[LG04900(ALL)07/95]
After completing 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.

you turn the ignition to the ON position, or if it
comes on and stays on when you are driving,
have your vehicle serviced as soon as possible.
[LG05560(ALL)03/94]
The 4WD light will go off after a few seconds
and stay off if all systems are operating
correctly. If a problem is detected, the 4WD
warning light will flash a certain number of
times indicating the location of the problem. The
flashing will continue until the problem is
corrected. Each time the ignition key is turned
on the controller will detect the problem and
flash the signal. The 4WD system remains safe to
operate and the vehicle should be returned for
service.

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)03/95]
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(ALL)08/95]
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.
[LG12752(ALL)08/95]
NOTE: The conversion constant can only be
changed six times once the vehicle
leaves the factory. Your Ford dealership
service personnel can change the
conversion constant.
*
[LG12753(ALL)08/95]
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.)
