FORD 2004 F-550 v.2 - Manual (Page 38)

Operating tips
• To reduce fog build up on the windshield during humid weather, place
the air flow selector in the position.
• To reduce humidity build up inside the vehicle: do not drive with the
air flow selector in the OFF or MAX A/C position.
• Do not put objects under the front seats that will interfere with the
airflow to the back seats.
• Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to “breathe” using the outside air inlet vents.
• Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
To aid in side window defogging/demisting in cold weather:
1. Select .
2. Select A/C.
3. Set the temperature control to maintain comfort.
4. Set the highest fan speed
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.
