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.
