hot and full cold positions, the air distributed through the floor ducts
will be slightly warmer than the air sent to the instrument panel
registers.
• FLOOR -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.
• FLR & 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 6°C
(43°F) or higher, the air conditioner will automatically dehumidify the
air to reduce fogging.
• DEF
-Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
temperature is about 6°C (43°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
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 or
MAX A/C position.
• To reduce humidity buildup inside the vehicle in warm 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.
