INFOID:0000000003888718
DESCRIPTION
If the temperature felt by the customer is different than the air flow temperature controlled by the temperature
setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.
HOW TO SET
Using CONSULT-III, perform “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC.
NOTE:
 When the temperature setting is set to 25.0°C (77°F) and −3.0°C (−6°F), the temperature controlled by A/C
auto amp. is 25.0°C (77°F) −3.0°C (6°F) = 22.0°C (71°F) and the temperature becomes lower than the tem-
perature setting.
 When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10
V or less, trimmer operation is canceled. Temperature set becomes that of initial condition.

AUTOMATIC AIR CONDITIONER SYSTEM
CLEAN Switch
 When the blower motor is operated, the indicator lamp of the clean switch illuminates by pressing the clean
switch. The air inlets are fixed to recirculation for approximately 5 minutes. After approximately 5 minutes
have passed, they change to the automatic re-circulation control system. The Plasmacluster ion generation
function operates for approximately 30 minutes (Blower motor operate) in clean mode after the clean switch
is ON. After approximately 30 minutes have passed, the vehicle is driven between ion control mode (approx-
imately 15 minutes) and clean mode (approximately 30 minutes) alternately.
NOTE:
When the clean switch is not ON
 Ignition switch: OFF
 Blower motor: OFF
 Mode position: Defroster (DEF)
 Ambient temperature: At about 0°C or below (Reactivate at about 2°C or above)
 When the gas sensor is malfunctioning
 The Plasmacluster ion generation function changes automatically to the ion control mode by turning the
clean switch OFF, and then operates for approximately 15 minutes. Then, it is operated between the clean
mode (approximately 15 minutes) and clean mode (approximately 15 minutes) alternately.
 When the clean switch is ON, the A/C switch is also turned ON in synchronization with the clean switch.
NOTE:
The A/C switch becomes deactivate and the clean switch is turned OFF in synchronization with the A/C
switch by the clean switch interlocking movement change function.
 Press the intake switch or defroster (DEF) switch when releasing the automatic recirculation control system.
A/C Switch
Compressor turns ON or OFF with this switch.
(Pressing the A/C switch when the A/C switch is ON turns OFF the A/C switch and compressor.)
Fan Control Dial
The blower speed is manually controlled with this dial. Seven speeds are available for manual control (as
shown on the display screen).
OFF Switch
Compressor and blower turn OFF, intake door and the mode doors are automatically controlled.
Rear Window Defogger Switch
When indicator is ON, rear window is defogged.
Intake Switch
 When the intake switch is ON, the intake switch indicator is turned ON, and air inlet is set to REC.
 When the intake switch is pressed again, the intake switch indicator is turned OFF, and air inlet is set to FRE.
 When the intake switch indicator is turned OFF, shifting mode position to DEF, intake switch is automatically
turned OFF (set to FRE mode). REC mode can be re-entered by pressing intake switch again.
DUAL Switch
 When the DUAL switch indicator is ON, the driver side and passenger side, temperature can each be set
independently.
 When the DUAL switch indicator is OFF, the driver side setting temperature is applied to both sides.

 Plasmacluster™ ion generation function, which generates ions inactivating bacteria and supplies to the pas-
senger compartment through air blown from air conditioner, has been adopted.
 Airborne mold and bacteria in the passenger compartment are inactivated by the effect of Plasmacluster
™
ion.
 Plasmacluster
™ ion generation function is switched between 2 operation modes (clean mode and ion control
mode) automatically, and maintain the ion balance in the passenger compartment close to that in nature.
 The operating condition is displayed in the “ION” indicator in the display.
NOTE:
 Plasmacluster
™ ion technology developed by Sharp Corporation is installed in this item.
 Plasmacluster
™ is a trademark of Sharp Corporation.
OPERATION DESCRIPTION
 The Plasmacluster™ ion generation function operates synchronized with the blower motor. The Plasmaclus-
ter
™ ion generation function operates when the blower motor operates.
 2 ion generation modes (clean mode and ion control mode) are switched every 15 minutes while blower
motor turns ON with ignition switch ON.
 When the clean switch is turned ON, Plasmacluster
™ ion generation function extends the operation time of
the clean mode to approximately 30 minutes for deactivating impurities more actively.
NOTE:
When the clean switch is not ON
 Ignition switch: OFF
 Blower motor: OFF
 Mode position: Defroster (DEF)
 Ambient temperature: At about 0°C (32°F) or below [Reactivate at about 2°C (36°F) or above]
 When the gas sensor is malfunctioning
 When the blower motor is stopped, the Plasmacluster
™ ion generation function also stops operating
(“CLEAN” and “ION” indicators are OFF).

AIR MIX DOOR CONTROL SYSTEM
When ignition switch is ON, the A/C auto amp. continuously and
automatically controls temperatures regardless of air conditioner
operational condition. When setting a target temperature with the
temperature control dial, the A/C auto amp. corrects the set temper-
ature and decides a target air mix door opening angle. The A/C auto
amp. controls air mix door according to the target air mix door open-
ing angle and current air mix door opening angle, keeping an opti-
mum air mix door opening angle. When the temperature is set at
18°C (60°F), air mix door is set on full cold, and when the tempera-
ture is set at 32°C (90°F), it is set to full hot.
