°
C – 32.0
°
C at
a rate of 0.5
°
C per adjustment.
- Clockwise: Setting temperature increases
- Counterclockwise: Setting temperature decreases
NOTE:
• When air conditioning is OFF, setting temperature can be set only while air conditioning status screen
(only when MODE switch is pressed) is indicated.
• Temperature control dial (passenger side) operation is not accepted when DEF mode is ON.
DEF switch
DEF mode (switch indicator) changes between ON
⇔
OFF each time switch is pressed.
• When this switch is pressed while air conditioning is ON
- Air conditioning becomes the following status when DEF mode is turned ON.
• Air outlet: DEF
• Air flow: Automatic control
• Air inlet: Fresh air intake
• A/C switch: ON
- Air conditioning becomes the following status when DEF mode is turned OFF.
• Air outlet: Settings set before DEF mode is turned ON
• Air flow: Settings set before DEF mode is turned ON
• Air inlet: Settings set before DEF mode is turned ON
• A/C switch: Settings set before DEF mode is turned ON
• When this switch is pressed while air conditioning is OFF
- Air conditioning turns ON and operates in the following status, when DEF mode is turned ON.
• Air outlet: DEF
• Air flow: Automatic control
• Air inlet: Fresh air intake
• A/C switch: ON
- Air conditioning becomes the following status when DEF mode is turned OFF.
• Air outlet: Settings set before DEF mode is turned ON
• Air flow: OFF
• Air inlet: Settings set before DEF mode is turned ON
• A/C switch: OFF
NOTE:
When DEF mode is turned ON while AUTO switch indicator is turned ON, AUTO switch indicator turns
OFF. However, automatic air flow control continues.
ON·OFF switch
Air conditioning turns ON
⇔
OFF each time this switch is pressed.
• When this switch is pressed while air conditioning is ON
- Air conditioning turns OFF and becomes the following status, when this switch is pressed.
• Air outlet: FOOT
• Air flow: OFF
• Air inlet: FRE
• A/C switch: OFF
• When this switch is pressed while air conditioning is OFF
- Air conditioning turns ON and operates according to the settings set before air conditioning is turned
OFF, when this switch is pressed.
REC switch
Switch indicator turns ON and air inlet is set to recirculation (REC), when this switch is pressed.
NOTE:
• Air inlet can be changed when air conditioning is in OFF status.
• When REC indicator is ON, pressing the REC switch for approximately 2 seconds or more, and then
the FRE and REC switch indicators blink twice and the system is switched to the automatic control.

AUTO switch
• AUTO switch indicator turns ON and air conditioning becomes the following status, when this switch is
pressed while air conditioning is ON.
- Air outlet: Automatic control
- Air flow: Automatic control
- Air inlet: Automatic control
- A/C switch: Settings set before this switch is pressed

DIAGNOSIS SYSTEM (A/C AUTO AMP.)
DIAGNOSIS SYSTEM (A/C AUTO AMP.)
Description
INFOID:0000000010432181
Air conditioning system performs self-diagnosis, operation check, function diagnosis, and various settings
using diagnosis function of each control unit.
CONSULT Function
INFOID:0000000010432182
CONSULT performs the following functions via CAN communication with A/C auto amp.
NOTE:
Diagnosis should be performed with engine running. Door motor operation speeds become slower and NO
results may be returned even for normal operation if battery voltage drops below 12 V during self-diagnosis.
