Switch Operation

AUTO switch	Turns the switch indicator lamp and "AUTO" indicator on the display ON, and then front air conditioning system becomes the following state. Air inlet: Automatic control Air outlet: Automatic control Blower fan: Automatic control Compressor: ON
Climate switch	Turns the display control unit to climate mode.
Defroster (DEF) switch	Turns DEF mode (switch indicator) between ON <=> OFF each time. When DEF switch is pressed while front air conditioning system is in the ON position. When DEF mode is turned ON, front air conditioning system becomes the following state. Air inlet: Fresh air intake Air outlet: DEF Blower fan: Automatic control (If fan speed other than AUTO is selected before pressing DEF switch, fan speed is manual control.) Compressor: ON When DEF mode is turned OFF, front air conditioning system state returns to the previous state before DEF mode is selected. But, the following state is continued. Air inlet: Fresh air intake Compressor: ON When DEF switch is pressed while front air conditioning system is in the OFF position. When DEF mode is turned ON, front air conditioning system becomes the following state. Air inlet: Fresh air intake Air outlet: DEF Blower fan: Automatic control Compressor: ON When DEF mode is turned OFF, entire front air conditioning system is set to auto mode. NOTE: When DEF mode turns ON while front air conditioning system is in automatic control ("AUTO" is indicated), automatic control is released ("AUTO" turns OFF).
SYNC switch	When SYNC mode is selected, "SYNC" is indicated on the display. Left, rear and right ventilation temperature separately control changes between ON <=> OFF each time this switch is pressed while blower motor is operated. NOTE: Setting temperature for passenger side and rear is the same as that for driver side when left and right ventilation temperature separately control is OFF. SYNC switch operation is not accepted when DEF mode is ON.
Fan switch (UP/DOWN)	Blower fan speed is manually controlled with these switches. Seven speeds are available for manual control (as shown on the display screen). NOTE: When fan switch is pressed while front air conditioning system is in OFF, front air conditioning system is activated. (Compressor control state returns to the previous state before front air conditioning system OFF.) When fan switch is pressed while front air conditioning system is in automatic control ("AUTO" is indicated), automatic control is released ("AUTO" turns OFF).
MODE switch	Selects air outlet sequentially from VENT => B/L => FOOT => D/F => VENT each time. NOTE: When front air conditioning system is in the OFF position, air outlet can be selected. When MODE switch is pressed while front air conditioning system is in automatic control ("AUTO" is indicated), automatic control is released ("AUTO" turns OFF).
OFF switch	Turns front air conditioning system OFF. When front air conditioning system turns OFF, air inlet and air outlet become the automatic control.
Intake switch	Air inlet changes between recirculation (REC) <=> fresh air intake (FRE) each time this switch is pressed. Intake switch indicator ON: Recirculation Intake switch indicator OFF: Fresh air intake NOTE: When front air conditioning system is in the OFF position, air inlet can be selected. When MODE switch and DEF switch is in the D/F or DEF position, air inlet cannot be selected to recirculation (REC).
Temperature control switch (Driver side)	Setting temperature is selected using this switch within a range between 18 deg.C (60 deg.F) and 32 deg.C (90 deg.F) at a rate of 0.5 deg.C (1.0 deg.F) per adjustment. Press: Setting temperature increases Press: Setting temperature decreases NOTE: When air conditioning system is OFF, setting temperature can be selected only while air conditioning system status screen [only when MODE switch (driver side) is pressed] is indicated on display.
Temperature control switch (Passenger side)	The system is set to LH/RH independent status ("SYNC" does not display) by operating this switch. Outlet air flow temperature of passenger side can be changed without changing outlet air flow temperature of driver side. Setting temperature is selected using this switch within a range between 18 deg.C (60 deg.F) and 32 deg.C (90 deg.F) at a rate of 0.5 deg.C (1.0 deg.F) per adjustment. Press: Setting temperature increases Press: Setting temperature decreases NOTE: When air conditioning system is OFF, setting temperature can be selected only while air conditioning system status screen [only when MODE switch (passenger side) is pressed] is indicated on display. When DEF mode is ON, temperature control switch (passenger side) is inoperative.
