1999 FORD TAURUS cooling

Operating tips
²In humid weather, selectbefore driving. This
will prevent your windshield from fogging. After a
few minutes, select any desired position.
²To prevent humidity buildup inside the vehicle,
don't drive with the climate control system in the
OFF position.
²Don't put objects under the front seat that will
interfere with the airflow to the back seats.
²Remove any snow,
ice or leaves from
the air intake area
(at the bottom of
the windshield
under the hood).
²If the air conditioner works well in MAX A/C, but
not in A/C, this may indicate that the cabin air
filter (if equipped) needs to be replaced.
²If your vehicle has been parked with the windows
closed during hot weather, the air conditioner will
do a much faster job of cooling if you drive for
two or three minutes with the windows open. This
will force most of the hot, stale air out of the
vehicle. Then operate your air conditioner as you
would normally.
²When placing objects on top of your instrument
panel, be careful to not place them over the
defroster outlets. These objects can block airflow
and reduce your ability to see through your
windshield. Also, avoid placing small objects on
top of your instrument panel. These objects can
fall down into the defroster outlets and block
airflow and possibly damage your climate control
system.
Controls and features

To control the
temperature, select any
temperature between
18ÉC (65ÉF) and 29ÉC
(85ÉF) by pressing the
temperature control.
For continuous maximum cooling, push the
temperature control until 16ÉC (60ÉF) is shown in
the display window. The EATC will continue
maximum cooling (disregarding the displayed
temperature) until a warmer temperature is selected
by pressing the temperature control.
For continuous maximum heating, push the
temperature control until 32ÉC (90ÉF) is shown in
the display window. The EATC will continue
maximum heating (disregarding the displayed
temperature) until a cooler temperature is selected
by pressing the temperature control.
Temperature conversion
Press MAX A/C and Fat the same time (until
the display changes) to switch between Fahrenheit
and Celsius.

When towing a trailer:
²Use D (Drive) or a lower gear when towing up or
down steep hills. This will eliminate excessive
downshifting and upshifting for optimum fuel
economy and transaxle cooling.
²Anticipate stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your maintenance guide and or service guide for
more information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.
Towing your vehicle behind another vehicle
At times, you may want to tow your vehicle behind
another vehicle, such as a recreational vehicle, car
or a truck.

Adding engine coolant
Do not put engine coolant in the reservoir
for the windshield washer fluid.
Use only Ford Premium Engine Coolant
E2FZ-19549±AA (in Oregon, F5FZ-19549±CC, in
Canada, Motorcraft CXC-10) or a premium
engine coolant that meets Ford specification
ESE-M97B44±A.
²DO NOT USE Ford Extended Life Engine
Coolant F6AZ-19544±AA (orange in color).
²DO NOT USE a DEX-COOLtengine coolant
or an equivalent engine coolant that meets
Ford specification WSS-M97B44±D.
²DO NOT USE alcohol or methanol antifreeze
or any engine coolants mixed with alcohol or
methanol antifreeze.
²DO NOT USE supplemental coolant additives
in your vehicle. These additives may harm
your engine's cooling system.
²DO NOT MIX recycled coolant and
conventional coolant together in your
vehicle. Mixing of engine coolants may harm
your engine's cooling system.
²The use of an improper coolant may harm
engine and cooling system components and
may void the warranty of your vehicle's
engine cooling system.
²Use only the type of coolant with which your
vehicle was originally equipped. If you are
unsure which type of coolant your vehicle
requires, contact your local dealer.
If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
When the engine is cool, add a 50/50 mixture of
engine coolant and distilled water to the engine
coolant reservoir.
