FORD 2001 F-550 v.1 - Manual (Page 29)

Operating tips
• In humid weather conditions, place the climate control system in
DEF 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
position.
• Under normal weather conditions, your vehicle’s climate control
system should be left in any position other than 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.
• Do not put objects under the front seat that will interfere with the
airflow to the rear seats (if equipped).
• Remove any snow, ice or leaves
from the air intake area at the
base of the windshield.
• Do not place objects over the defroster outlets. These objects may
block airflow and reduce visibility through the 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.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or a sudden stop.
