Whenever press the SWITCH,
temperature is changed 0.5°C up/down each time. (Each
time the operation sound is made for 0.1

When changing the set temperature
from 17.5°C to 17°C or from 31.5°C to 32°C, the
operation sound is
made. |
6. |
At 17°C, if the temperature is set
below than 17°C or at 32°C , if it is above than 32°C ,
the operation sound is made 5times at an interval of

When pushing the TEMP button
several times, the set temperature is shifted to another

Electromotive
cooling control
|
In order to
prevent hot air from the VENT or B/L in AUTO mode (A/C on mode), the
blower speed will be operated at LOW for approx. 9 seconds before
enteringthe AUTO control if the EVAP sensor detection is temperature

Air
Quality System (AQS)
|
The AQS system
will detect the hazardous elements and odors contained in the air.If
the harmful element concentration is higher than standard, the
system willoutput a LOW signal (0V) to the FATC.
|
-
|
When the initial battery connection and
ignition is ON, it will operate at AUTO mode. (AQS will not
operate). | |
If the
concentration is within the standard value, the system will output a
HI signal(3V) the FATC.
|
-
|
When IGN 2 ON, the AQS assembly will be
preheated for 34.5 ± 5seconds.During the preheating, AQS will
output 0V (ground). (REC

Corresponding to
the signal from the AQS, it will control the INTAKE door as follows
toprevent the inflow of harmful gas in FATC :
|
-
|
IGN 2 ON: It will check circuit break on
the AQS assembly's signal line for approx. 7 seconds during
the preheating, irrespective to the AQS switch
condition. | |
Condition :
