1999 Mercury Sable cooling

²-Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog
from the windshield. If the temperature is about
10ÉC (50ÉF) or higher, the air conditioner will
automatically dehumidify the air to prevent fogging.
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.
²
When 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.

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 F-DEFat the same time
(until the display changes) to switch between
Fahrenheit and Celsius.
Fan speed ()
When AUTO is
pressed, fan speed is
adjusted automatically
for existing conditions.
You can override fan
speed at any time. To
control fan speed
manually, press the fan

Do not connect a trailer's hydraulic brake
system directly to your vehicle's brake
system. Your vehicle may not have enough braking
power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for
operation at the GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles.
Make sure your trailer lamps conform to local and
Federal regulations. See your dealer or trailer rental
agency for proper instructions and equipment for
hooking up trailer lamps.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when
towing a trailer. Do not drive faster than 72 km/h
(45 mph) with any weight on the trailer while
towing on a hot day or in hilly country.
Speed control may shut off if you are towing on
long, steep grades.
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.
Before you have your vehicle towed:
²Release the parking brake.
²Turn the key in the ignition to OFF.
²Move the gearshift to N (Neutral).
²Unlock the steering wheel.
Do not tow your vehicle at a speed faster than
56 km/h (35 mph) or for a distance greater than
80 km (50 miles), unless the drive wheels are placed
on dollies.

10. Return the flat tire,
jack and lug wrench to
their proper storage
locations. Make sure
the jack is fastened so
it does not rattle when
you drive.
11. Unblock the
wheels.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An
explosion could result in injury or vehicle damage.
Do not push start your vehicle. You could
damage the catalytic converter.
Batteries contain sulfuric acid which can
burn skin, eyes, and clothing, if contacted.
Do not attempt to push start your vehicle.
Automatic transmissions do not have
push-start capability.
Preparing your vehicle
1.
Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled
vehicle as this could damage the vehicle's electrical
system.
3. Park the booster vehicle close to the hood of the
