FORD 2002 F-150 - Manual (Page 57)

• FLOOR – Allows for maximum heating by distributing 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.
• FLR & DEF – 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 6°C
(43°F) or higher, the air conditioner will automatically dehumidify the
air to reduce fogging.
• DEF
– 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 6°C (43°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
Operating tips
• In 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.
• To 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.
• To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF
position.
• Under 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 “breathe”
through the outside air inlet duct.
• Under 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.
• If 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 “aired out”, operate the climate
control system as desired.
