2002 FORD F750 Owners Manual

²(Floor) ± Distributes outside air through the floor ducts.
²
(Floor and defrost) ± Distributes outside air through the floor
ducts and the windshield defroster ducts.
²
(Defrost) ± Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
Operating tips
²In humid weather, place the climate control system in DEF before
driving. This will reduce fogging on your windshield. Once the
windshield has been cleared, select any desired position.
²To reduce humidity buildup inside the vehicle, do not drive with the
climate control system in the OFF position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than OFF position when
the vehicle is parked. This allows the vehicle to ªbreatheº through the
outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²Do not place objects under the front seat which may interfere with
the airflow to the rear seats.
²Remove any snow, ice, or leaves from the air intake area (at the base
of the windshield and underneath the hood).
²Do not place objects over the defroster outlets. These objects may
block airflow and reduce your visibility through the windshield. Avoid
placing small objects on top of the instrument panel. These objects
can fall into the defroster outlets and block airflow, in addition to,
damaging your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in instances of sudden impact or
a sudden stop.

Fan speed control
Controls the volume of air circulated
in the vehicle.
Temperature control knob
Controls the temperature of the
airflow inside the vehicle.
Mode Selector Control
Controls the direction of the airflow
to the inside of the vehicle.
The air conditioning compressor can operate in all modes except
and. However, the air conditioning will only function if the outside
temperature is about 6ÉC (43ÉF) or higher.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
²MAX A/C ± Uses recirculated air to cool the vehicle. MAX A/C is
noisier than A/C but more economical and will cool the inside of the
vehicle faster. Airflow will be from the instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle.
²A/C ± Uses outside air to cool the vehicle. It is quieter than MAX A/C
but not as economical. Airflow will be from the instrument panel
registers.
²
(Panel) ± Distributes outside air through the instrument panel
registers. However, the air will not be cooled below the outside
temperature because the air conditioning does not operate in this
mode.

²OFF ± Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
²
(Panel and floor) ± Distributes outside air through the
instrument panel registers and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
instrument panel registers.
²
(Floor) ± Distributes outside air through the floor ducts.
However, the air will not be cooled below the outside temperature
because the air conditioning does not operate in this mode.
²
(Floor and defrost) ± Distributes outside air through the
windshield defroster ducts and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, the air distributed through the floor ducts will be
slightly warmer than the air sent to the windshield defroster ducts. If
the temperature is about 6ÉC (43ÉF) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
²
(Defrost) ± 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 6ÉC (43ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
Operating tips
²In humid weather conditions, place the climate control system in
Defrost mode before driving. This will reduce fogging on your
windshield. Once the windshield has been cleared, operate the climate
control system as desired.
²To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF or
MAX A/C position.
²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.

²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than the MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.
²Do not put objects under the front seat which may interfere with the
airflow to the rear seats (if equipped).
²Remove any snow, ice or leaves from the air intake area (at the
bottom of the windshield and underneath the hood).
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce visibility through your windshield. Avoid
placing small objects on top of the instrument panel. These objects
may fall down into the defroster outlets and block airflow, in addition
to, damaging the climate control system.
To aid in side window defogging/demisting in cold weather conditions:
1. Select the position that distributes air through the Panel and Floor.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Lamp (DRL) system
does not activate with your tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.
Foglamp control (if equipped)
The headlamp control also operates
the foglamps. The foglamps can be
turned on only when the headlamp
control is in the
position and
the high beams are not turned on.
Pull headlamp control towards you
to turn foglamps on. The foglamp
indicator light
will illuminate.
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel during headlamp
and parklamp operation.
²Rotate up to brighten.
²Rotate down to dim.
²Rotate to full up position (past
detent) to turn on interior lamps.
²Rotate to full down position (past
detent) to turn off interior lamps.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident the alignment of your headlamps
should be checked by a qualified service technician.
