cl If manual switching of air intake is de-
sired
UNX506
The air intake control button is used to switch
the air intake between the OUTSIDE AIR
mode and RECIRCULATED AIR mode.
With the button in the OUTSIDE AIR mode,
the OUTSIDE AIR mode indicator light will
come on and the system will take fresh out-
side air into the vehicle.
If quick circulation of cooled air is desired,
push the air intake control button for RECIR-
CULATED AIR. The RECIRCULATED AIR
mode indicator light will come on.
For normal use, it is best to keep the air in-
take control button set to OUTSIDE AIR
mode. If recirculated air is used during heat-
ing, the windows will fog up more easily.If the engine coolant temperature becomes
extremely high, the RECIRCULATED AIR
mode is automatically selected. This is not
a malfunction. When the engine coolant
temperature is lowered, the previous mode
resumes.
In the following cases, the RECIRCULATED
mode may change to the OUTSIDE AIR
mode automatically to prevent interior fog.
When the outside temperature becomes
lower than 4C (39F).
When the air conditioning compressor
malfunctions.
When the air conditioning cooler refriger-
ant decreases.If manual on off of the air conditioning is
desired
Push the “A/C” switch to turn the air condi-
tioning on and push it again to turn the air
conditioning off. If you turn off the air condi-
tioning manually, the EXHAUST GAS AU-
TOMATIC mode will be cancelled.
If the outside temperature is lowered down to
around 0C (32F), the air conditioning will
turn off automatically. At this time, the indica-
tor on the A/C button is off and the EX-
HAUST GAS AUTOMATIC indicator light re-
mains on. However, the EXHAUST GAS
AUTOMATIC mode does not operate.
When the air conditioning turns on as with
the raised temperature, the EXHAUST GAS
AUTOMATIC mode resumes.
If the system is used for ventilation, heating
in dry weather or removing frost or exterior
fog on the windshield, turn the air condition-
ing off once it is no longer required. This will
improve fuel economy. The air conditioning
can be used for year−round automatic tem-
perature control including cooling and dehu-
midifying operation.
