F-250 Light Duty (1999 year). Manual — part 7

Operating tips
• In humid weather, select

before driving. This will reduce your

windshield from fogging. After a few minutes, select any desired
position.

• To prevent humidity buildup inside the vehicle, don’t drive with the

climate control system in the OFF position.

• Don’t put objects under the front seat that will interfere with the

airflow to the back seats (if equipped).

• Remove any snow, ice or leaves

from the air intake area (at the
bottom of the windshield under
the hood).

• If 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.

• 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.

Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
