INFOID:0000000006275874
• When ignition switch is in the ON position, A/C auto amp. always
automatically controls temperature regardless of rear air condition-
ing operational state.
• A/C auto amp. calculates the target rear air mix door opening
angle depending on set temperature, in-vehicle temperature (rear
side), ambient temperature, and sunload.
• Rear air mix door is controlled depending on the comparison of
current rear air mix door opening angle and target front air mix
door opening angle.
• Regardless of in-vehicle temperature (rear side), ambient tempera-
ture, and sunload, rear air mix door is fixed at the fully cold position
when set temperature is 18.0
°
C (60
°
F), and at the fully hot position
when set temperature is 32.0
°
C (90

ACCS (ADVANCED CLIMATE CONTROL SYSTEM) : System Description
INFOID:0000000006275876
• ACCS (advanced climate control system) controls passenger room air. It maintains the cleanliness of the
passenger room air using an in-cabin microfilter and a combination of each of the following functions.

NOTE:
• Plasmacluster
™
ion technology developed by Sharp Corporation is installed in this item.
• Plasmacluster
™
is a trademark of Sharp Corporation.
• Various operations of ACCS (advanced climate control system) are transmitted from preset switch to AV
control unit via communication line and from AV control unit to A/C auto amp. via CAN communication. A/C
auto amp. sends each indication information to AV control unit via CAN communication. AV control unit dis-
plays each indication information that is received.
ACCS (ADVANCED CLIMATE CONTROL SYSTEM) : Automatic Intake Control (Ex-
haust Gas / Outside Odor Detecting Mechanism)
INFOID:0000000006275877
DESCRIPTION
In addition to air inlet automatic control of front automatic air conditioning system, A/C auto amp. controls
automatically air inlet according to signal from exhaust gas / outside odor detecting sensor, so that unpleasant
outside odor does not enter in passenger room.
OPERATION DESCRIPTION
• When pressing auto intake switch while front blower motor is operated and DEF switch is OFF, auto intake
switch indicator lamp and intake switch indicator lamp turn ON. Air inlet is fixed to recirculation for approxi-
mately 5 minutes, and then is switched to automatic intake control (exhaust gas / outside odor detecting
mechanism).
• Air inlet switches to recirculation when exhaust gas or outside odor is detected while automatic intake control
(exhaust gas / outside odor detecting mechanism) is operated. After that, air inlet switches to fresh air intake
when exhaust gas or outside odor becomes not detectable.

INFOID:0000000006275878
DESCRIPTION
Plasmacluster
™
control eliminates microbes and reduces odor on interior surface by including high density
Plasmacluster
™
ion in air conditioning outlet air flow.
OPERATION DESCRIPTION
• Plasmacluster
™
control operates by interlocking to blower motor. Plasmacluster
™
control operates when
blower motor operates.
• Control status is displayed on front air conditioning system display screen. Refer to
(ADVANCED CLIMATE CONTROL SYSTEM) : Switch Name and Function"
