[AUTOMATIC AIR CONDITIONING]

HAC

• In D-MODE: The following switches and dial cannot be operated.

- A/C switch

- OFF switch

- MODE switch

- Fan control dial

DEF switch

DEF mode turns ON

⇔ OFF each time when switch is pressed.

• When switch is pressed while air conditioning system is in the ON position.
- Air conditioning system operates according to the following setting when DEF mode is turned ON.
• Air outlet: DEF
• Air flow: Previous setting before turning DEF mode ON
• Air inlet: Fresh air intake
• A/C switch*: ON
- Air conditioning system operates according to the following setting when DEF mode is turned OFF.
• Air outlet: Previous setting before turning DEF mode ON
• Air flow: Previous setting before turning DEF mode OFF
• Air inlet: Fresh air intake
• A/C switch: Previous setting before turning DEF mode OFF
• When switch is pressed while air conditioning system is in the OFF position.
- Air conditioning system turns ON and operates according to the following setting when DEF mode

is turned ON.

• Air outlet: DEF
• Air flow: Automatic control
• Air inlet: Fresh air intake
• A/C switch*: ON
- Air conditioning system operates according to the following setting when DEF mode is turned OFF
• Air outlet: Automatic control
• Air flow: Previous setting before turning DEF mode OFF
• Air inlet: Fresh air intake
• A/C switch: Previous setting before turning DEF mode OFF
NOTE:
• When DEF mode is turned ON while “AUTO” is indicated on display, “AUTO” indication turns OFF.

However, air flow automatic control continues.

• *: A/C switch (compressor control) is turned ON when DEF switch is turned ON while A/C switch

indicator is OFF, but A/C switch indicator is not turned ON.

Intake switch

• Air inlet changes between recirculation (REC)

⇔ fresh air intake (FRE) each time this switch is

pressed.

switch indicator ON: Recirculation

*1, 2

switch indicator ON: Fresh air intake

• Switch indicator blinks 2 times and air inlet is set to automatic control when switch is pressed and

held for 2 seconds or more. (Switch indicator indicates air inlet status during automatic control.)

*1: A/C switch turns ON when recirculation (REC) is selected while air conditioning system is in the
ON position.
*2: A/C switch (compressor control) is turned ON when recirculation (REC) is selected while A/C
switch indicator is OFF, but A/C switch indicator is not turned ON.
NOTE:
• Air inlet can be changed when air conditioning system is in the OFF position.
• Air inlet cannot be changed to recirculation (REC) when air outlet is in the D/F or DEF position.
• Air inlet automatic control is released when A/C switch is in the OFF position.

Fan control dial

• Air flow can be manually set within a range of 1st – 7th speed using this dial.
- Clockwise rotation: Air flow increases
- Counterclockwise rotation: Air flow decreases
• Air conditioning system turns ON and operates according to the following setting when this dial is

turned one click to the left or right while air conditioning system is OFF.

- Air outlet: Automatic control
- Air flow: 1st speed
- Air inlet: Automatic control
- A/C switch: Previous setting before turning air conditioning system OFF
NOTE:
Air flow automatic control is released (“AUTO” turns OFF) when this dial is operated while “AUTO” is
indicated on display.

DIAGNOSIS SYSTEM (A/C AUTO AMP.)

DIAGNOSIS SYSTEM (A/C AUTO AMP.)

Description

INFOID:0000000012200019

Air conditioning system performs self-diagnosis, operation check, function diagnosis, and various settings

using diagnosis function of each control unit.

CONSULT Function

INFOID:0000000012200020

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-33, "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
