air distributed through the floor
ducts will be slightly warmer
than the air sent to the
instrument panel registers.
²FLOOR-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.
²FLR & 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 10ÉC
(50ÉF) or higher, the air
conditioner will automatically
dehumidify the air to prevent
fogging.

Operating tips
²In humid weather, select DEF
before driving. This will
prevent your windshield from
fogging. After a few minutes,
select any desired position.
²To prevent humidity buildup
inside the vehicle, don't drive
with the climate control system
in the OFF position.
²Don't put objects under the
front seat that will interfere with
the airflow to the back seats (if
eqipped).
²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under
the hood).
²If 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.
²When placing objects on top of
your instrument panel, be
careful to not place them over
the defroster outlets. These
objects can block airflow and
