[ST11100( ALL)04/95]
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
normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.

[ST11210( ALL)05/95]
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.
*
[ST11225( ALL)05/95]
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.
*
[ST11250( ALL)05/95]
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.
*
[ST11300( ALL)03/95]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[ST11400( ALL)03/95]
Engine Block Heater (If equipped)
*
[ST11500( ALL)03/95]
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.
*
[ST11700( ALL)02/95]
To turn the heater on, simply plug it into a
grounded 110-volt outlet. Ford recommends that
you use a 110-volt circuit that is protected by a
ground fault circuit interrupter.

vents clear of snow, leaves, and other debris.
[ST14000( ALL)12/94]
If the engine is idling while you are stopped in
an open area for long periods of time, open the
windows at least one inch (2.5 cm). Also, the
heating or air conditioning system should be set
to any function except MAX A/C or AUTO.
[ST14125( BCGV)05/94]

If you use the heater, set the fan speed on
MEDIUM or HIGH with the function control
on any position except OFF and the
temperature control at any desired position.

The Mechanical Cluster

[LG02800( BCGV)06/93]
The following warning lights and gauges are on
the mechanical cluster. All of the warning lights
and gauges alert you to possible problems with
your vehicle. Some of the lights listed are
optional. The following sections detail what each
of these indicators means.

[LG02900( ALL)03/95]
Brake System Warning Light
*
[LG03000( ALL)03/95]
The warning light for the brakes can show two
things Ð that the parking brake is not fully
released, or that the brake fluid level is low in
the master cylinder reservoir. If the fluid level is
low, the brake system should be checked by a
qualified service technician.
[LG03035( GV)05/95]
one inch art:0010681-C[LG03100( ALL)01/95]
This light comes on when the parking brake is
set, or if it is not set, it comes on briefly when
you turn the ignition key to START. It normally
goes off shortly after the engine starts and you
release the parking brake. If the light stays on
after you have fully released the parking brake,
have the hydraulic brake system serviced.
*
[LG03200( ALL)05/95]
RWARNING
The BRAKE light indicates that the brakes
may not be working properly. Have the
brakes checked immediately.

50 % [LG03475( ALL)05/94]Anti-Lock Brake System Light
(If equipped)
[LG03500( ALL)05/94]
This warning light will go on each time you
start your vehicle. If it remains on for longer
than five seconds, you should shut off your
engine and restart. If the anti-lock brake light
stays on, this indicates that the anti-lock feature
is disabled and should receive immediate
attention by a qualified service technician.
Normal braking is not affected unless the brake
warning light is also lit.
*
[LG03505( BCGV)01/95]
The Anti-Lock Brake System has self-check
capabilities. As previously described, the system
turns on the anti-lock light each time you start
your engine. After the engine is started and the
anti-lock light is out, the system performs
another test the first time the vehicle reaches
14 mph (22 km/h). The system turns on the
Anti-Lock Brake System (ABS) pump motor for
approximately 1/2 second. At this time a
mechanical noise may be heard. This is a normal
part of the self-check feature. If a malfunction is
found during this check the anti-lock light will
come on.

Air Bag Readiness Light
[LG04620( ALL)05/94]
The air bag system uses a readiness light to
indicate the condition of the system. If the
system is functioning properly, the light will
stay on for 6 seconds when the ignition switch is
turned to the ON position.
[LG04630( ALL)05/94]
If there is a problem with the system, two things
may happen: the readiness light will either flash
or stay lit up, or you will hear a beeping sound.
If either of these things happen, have the air bag
system serviced at your Ford or Lincoln-Mercury
dealer immediately.

Overdrive Off Indicator
[LG05210( ALL)06/93]
one inch art:0010730-A*
[LG05220( BCGV)01/95]
This light tells you that the Transmission Control
Switch (TCS) on the gearshift lever has been
pushed. When the light is on, the transmission
will not shift into overdrive. Depressing the
button on the shifter will return the vehicle to
ªoverdrive onº mode. The transmission will be
in the ªoverdrive onº mode when the vehicle is
started even if the O/D OFF mode was selected
when the vehicle was last shut off.
*
[LG05230( ALL)04/95]
NOTE: If the light does not come on when the
TCS is depressed or if the light flashes
when you are driving, have your
vehicle serviced at the first
opportunity. If this condition persists,
damage could occur to the
transmission.

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

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
