Controls and features • 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 10°C (50°F) or higher, the air conditioner will automatically dehumidify the air to reduce fogging. Operating tips • In humid weather, select DEF before driving. This will reduce fogging on your windshield. After a few minutes, select any desired position. • To reduce 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. • 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. 32
