play when MODE switch is pressed while air conditioning system is OFF.
- In D-MODE: Operation status of air conditioning system (setting temperature, A/C switch, and “AUTO”
*2
) is
indicated on lower portion of display when air conditioning system is turned ON. Setting temperature is indi-
cated on display when MODE switch is pressed while air conditioning system is OFF.
NOTE:
*1: AUTO is indicated when both air flow and air outlet are in automatic control.
*2: Air Flow is indicated when air flow or air outlet is in manual control.

When either of following operation is performed while A/C switch indicator is OFF, compressor control
change to ON but A/C switch indicator is not turned ON.
• AUTO switch is turned ON.
• Air outlet is set to D/F by MODE switch operation.
• Air outlet is set to DEF by DEF switch operation.
• Air inlet is changed to recirculation (REC) by intake switch operation.
OFF switch
Air conditioning system turns OFF and changes to the following status when switch is pressed while
air conditioning system is in the ON position.
• Air outlet: Foot
• Air flow: OFF
• Air inlet: Fresh air intake
• A/C switch: OFF

°
C (60
°
F) – 32
°
C (90
°
F) at a rate of 0.5
°
C (1

per adjustment using this dial.
• Clockwise rotation: Set temperature increases
• Counterclockwise rotation: Set temperature decreases
NOTE:
When air conditioning system is OFF position, setting temperature can be selected only while air con-
ditioning system state (when MODE switch is pressed) is indicated on the display.
AUTO switch
“AUTO” is indicated on display and air conditioning system operates according to the following setting
when switch is pressed.
• Air outlet: Automatic control
• Air flow: Automatic control
• Air inlet: Automatic control
• A/C switch*: ON
NOTE:
• When air outlet or air flow is manually operated while “AUTO” is indicated on display “AUTO” indi-
cation turns OFF. However, automatic control continues for other functions than air outlet or air flow.
• *: A/C switch (compressor control) is turned ON when AUTO switch is turned ON while A/C switch
indicator is OFF, but A/C switch indicator is not turned ON.
MODE switch
When each MODE switch is pressed, air outlet is switched and VENT, B/L, FOOT, or D/F
*1,2
can be
selected manually. (Switch indicator indicates air outlet status during automatic control.)
*1: Air inlet is set to fresh air intake (FRE) and A/C switch turns ON, when D/F is selected while air
conditioning system is in the ON position.
*2: A/C switch (compressor control) is turned ON when D/F is selected while A/C switch indicator is
OFF, but A/C switch indicator is not turned ON.
NOTE:
• Air outlet can be changed when air conditioning system is in the OFF position.
