*
[ST07350( 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.
*
[ST07400( 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.
*
[ST07450( 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.
*
[ST07500(BEF )03/95]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[ST07600(BEF )03/95]
Engine Block Heater (If equipped)
(Standard in Canada)
*
[ST07700(BEF )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.
*
[ST08000(BEF )05/95]
RWARNING
To prevent electrical shock, do not use
your heater with ungrounded electrical
systems or two-pronged (cheater) adapters.

Engine Coolant Temperature Gauge
*
[LG11201( ALL)03/95]
This gauge tells you the temperature of the
engine coolant, not the coolant level. If the
coolant is not at its proper level or mixture, the
gauge indicator will not be accurate.
*
[LG11301( ALL)02/95]
The pointer moves from the C (cold) mark into
the Normal band as the engine coolant warms
up. It is acceptable for the pointer to fluctuate
within the Normal band under normal driving
conditions. Under certain driving conditions,
such as heavy stop and go traffic or driving up
hills in hot weather, the pointer may indicate at
the top of the Normal band.
*
[LG11401( ALL)05/95]
If, under any circumstances, the pointer moves
above the NORMAL band, the engine coolant is
overheating and continued operation may cause
engine damage.
*
[LG11501( ALL)01/95]
If your engine coolant overheats:
*
[LG11601( ALL)03/95]
1. Pull off the road as soon as it is safely
possible.
*
[LG11701( ALL)03/95]
2. Turn off the engine. If you do not stop the
engine as soon as safely possible, severe
engine damage could result.
*
[LG11801( ALL)05/95]
3. Let the engine cool.DO NOT REMOVE
COOLANT SYSTEM FILL CAP UNTIL
THE ENGINE IS COOL.
*
[LG11901( ALL)04/95]
4. Check the coolant level following the
instructions on checking and adding coolant
to your engine, seeEngine Coolantin the
Index. If you do not follow these
instructions, you or others could be injured.
*
[LG12200( ALL)03/95]

to your engine, seeEngine coolantin the Index. If
you do not follow these instructions, you or
others could be injured.

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).

NOTE: Do not use an engine coolant that does
not meet all 14 requirements of Ford
Specification ESE-M97B44-A. The use
of an improper coolant may void your
warranty for the engine cooling system.
Use only a premium nationally
recognized brand name engine coolant.
*
[SV19960( ALL)05/95]
Ford Motor Company expressly authorizes the
Ford Rotunda engine coolant recycling process
and chemicals. Use only Ford Rotunda recycled
engine coolant or an equivalent recycled engine
coolant that is certified by the supplier to meet
Ford specification ESE-M97B44-A.
%*
[SV19980( ALL)04/95]
NOTE: Always dispose of used automotive
fluids in a responsible manner. Follow
your community's standards for
disposing of these types of fluids. Call
your local recycling center to find out
about recycling automotive fluids.
*
[SV20001( ALL)01/95]
Use Ford Premium Cooling System Fluid or an
equivalent engine coolant that meets Ford
Specification ESE-M97B44-A. Do not use alcohol
or methanol antifreeze and do not use engine
coolant mixed with alcohol or methanol
antifreeze. If you do not use the proper coolant,
the aluminum radiator on your vehicle will
corrode.
*
[SV20100( ALL)01/95]
Leave the engine coolant in all year. Make sure
that the coolant will not freeze at the
temperature level in which you drive during
winter months. Keep a mixture of engine coolant
in your engine that has a protection rating of at
least-34ÊF (-37ÊC), orwhatever protection rating
is appropriate for the climate in which you live.

your vehicle's coolant system can hold, seeRefill

If the wiper blades still do not work properly
after you clean them, you may need to replace
the wiper blade assembly or the blade element.
When replacing the wiper blade assembly, blade
refill, or wiper arm always use a Motorcraft part
or equivalent. To replace the blades, follow the
instructions that come with them.
%*
[SV23850(BEF )01/95]
Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such
as methanol should be used in freezing weather
(temperatures below32ÊF [0ÊC]).State or local

Power Steering Fluid
*
[SV37700( ALL)01/95]
Check the level of the power steering fluid at
least twice a year (i.e., every Spring and Fall).
*
[SV37800( ALL)03/95]
To check the level of your power steering fluid:
*
[SV37900( ALL)02/95]
1. Start the engine and let it run until the
power steering fluid reaches normal
operating temperature. The power steering
fluid will be at the right temperature when
the engine coolant temperature gauge in the
instrument cluster is near the center of the
NORMAL operating temperature range.
*
[SV38000( ALL)01/95]
2. While the engine idles, turn the steering
wheel back and forth several times. Make
sure that the cap assembly is installed at this
time.
*
[SV38100(BEF )05/95]
3. Turn the engine off.
%*
[SV38200( ALL)03/94]
4. Check the fluid level on the dipstick (which
is highlighted in yellow in your vehicle). The
fluid level should be between the arrows in
the FULL HOT range, which is marked on
the side of the dipstick, opposite the side
marked FULL COLD. Do not add fluid if the
level is within the FULL HOT range.
