DESCRIPTION

ACCS (advanced climate control system) controls passenger room air. It maintains the cleanliness of the passenger room air using a high performance filter and a combination of each of the following functions.

Automatic intake control (exhaust gas/outside odor detecting mechanism)
Plasmacluster™ ion

AUTOMATIC INTAKE CONTROL (EXHAUST GAS/OUTSIDE ODOR DETECTING MECHANISM)

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 exhaust gas and unpleasant outside odor does not enter in passenger room.

Operation Description

When AUTO intake switch is pressed while front blower motor is activated, AUTO intake indicator and REC indicator turn ON. Air inlet is fixed to recirculation for approximately 5 minutes, and then is switched to automatic intake control (exhaust gas/outside odor detecting mechanism).
Air inlet switches to recirculation when ambient atmospheric CO, NO2 and unpleasant 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 and unpleasant outside odor becomes not detectable.
Control status is displayed on front A/C control display screen. Refer to "REAR AUTOMATIC AIR CONDITIONING SYSTEM : SWITCH NAME AND FUNCTION ".

NOTE:
- Sensitivity of exhaust gas/outside odor detecting sensor can be changed. Refer to "EXHAUST GAS/OUTSIDE ODOR DETECTING SENSOR SENSITIVITY ADJUSTMENT FUNCTION ".
- Automatic intake control (exhaust gas/outside odor detecting mechanism) does not operate when air outlet is D/F, DEF mode or ambient temperature is 0°C (32°F) or less. In this case, control is only for control of automatic air inlet of automatic air conditioning system.

PLASMACLUSTER™ ION

Description

Plasmacluster™ ion restrains microbes, reduces odor on interior surface, and maintains passenger's skin moisture* by including high density Plasmacluster™ ion in front air conditioning outlet air flow.

*: Effect depends on individual difference and operating conditions. Tasted by Soiken CO., Ltd. Ion density is 25,000 pcs/cm³ . Skin moisture is measured at the temple of person being tested.

NOTE:

Plasmacluster™ ion technology developed by Sharp Corporation is installed in this item.
Plasmacluster™ is a trademark of Sharp Corporation.

Operation Description

Plasmacluster™ ion operates by interlocking to front blower motor. Plasmacluster™ ion operates when front blower motor operates.
Control status is displayed on front A/C control display screen. Refer to "REAR AUTOMATIC AIR CONDITIONING SYSTEM : SWITCH NAME AND FUNCTION ".
