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 approximately 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.

NOTE:

Sensitivity of exhaust gas / outside odor detecting sensor can be changed by "GAS SENSOR ADJUSTMENT" in "WORK SUPPORT" mode of CONSULT. Refer to EXHAUST GAS / OUTSIDE ODOR DETECTING SENSOR SENSITIVITY ADJUSTMENT FUNCTION .
Automatic intake control (exhaust gas / outside odor detecting mechanism) does not operate when ambient temperature is - 2°C (28°F) or less. In this case, control is only for control of automatic air inlet of automatic air conditioning system.
