Defog Mode

The defog mode splits the air between the heater (floor ducts) and the defroster. The A/C clutch engages when the outside temperature is above 6°C (42°F) in order to help dehumidify the air. The defog mode is enabled by pressing DEFOG on vehicles without Console, Front Compartment Floor or by pressing the mode select button on vehicles with Console, Front Compartment Floor.
