OPERATION

Temperature control
dial (passenger side)

• Left and right ventilation temperature separately control (DUAL switch indicator) turns ON according

to dial operation. Air flow temperature of passenger side can be changed without changing air flow
temperature of driver side.

• Setting temperature can be set according to dial operation within a range between 18.0

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
• Air conditioning turns ON and operates according to the following status, when this switch is pressed

while air conditioning is OFF. (AUTO switch indicator turns ON)

- Air outlet: Automatic control
- Air flow: Automatic control
- Air inlet: Automatic control
- A/C switch: Settings set before this switch is pressed
NOTE:
When air outlet or air flow is manually operated while AUTO switch indicator is ON, AUTO switch indica-
tor turns OFF. However, automatic control continues for other functions than air outlet or air flow.

FRE switch

Switch indicator turns ON and air inlet is set to fresh air intake (FRE), when this switch is pressed.
NOTE:
Air inlet can be changed when air conditioning is in OFF status.
When FRE indicator is ON, pressing the FRE 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.

DUAL switch

Left and right ventilation temperature separately control (switch indicator) changes between ON

⇔

OFF

each time this switch is pressed while blower motor is operated.
NOTE:
• Setting temperature for passenger side is the same as that for driver side when left and right ventilation

temperature separately control is OFF.

• DUAL switch operation is not accepted when DEF mode is ON.

A/C switch

Compressor control (switch indicator) changes between ON

⇔

OFF each time this switch is pressed

while blower motor is operated.
NOTE:
A/C switch cannot be turned ON when blower motor is OFF.

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.

ECU IDENTIFICATION

Part number of A/C auto amp. can be checked.

SELF-DIAGNOSIS RESULTS

Diagnosis result that is judged by A/C auto amp. can be checked. Refer to

HAC-53, "DTC Index"

DATA MONITOR

Input/output signal of A/C auto amp. can be checked.
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
