O (Off) – Outside air is shut out and the fan will not operate. This
mode may reduce undesirable odors from entering the vehicle but may
increase the possibility of interior window fogging.
(Floor) – Distributes outside air through the floor ducts. The air
cannot be cooled below the outside temperature.
(Floor and defrost) – Distributes outside air through the
windshield defroster ducts and the floor duct and the side window
demisters. The A/C compressor will operate automatically if the
outside temperature is above approximately 6°C (43°F) . The air
distributed through the floor ducts will be slightly warmer than the air
sent to the windshield defrost ducts and the side window demisters.
(Defrost) – Distributes outside air through the windshield
defroster ducts and the side window demisters. The A/C compressor
will operate automatically if the outside temperature is above
approximately 6°C (43°F). This mode will clear ice and fog from the
windshield.
Since the air conditioner removes moisture from the air, it is
considered normal operation if water drips on the ground under
the air conditioner drain.
