Each time you push the air intake control button, the mode
changes in order from the RECIRCULATED AIR mode to
AUTOMATIC mode to OUTSIDE AIR mode, then back to the
RECIRCULATED AIR mode. Each indicator light shows which
mode is now selected.
1 RECIRCULATED mode − If quick circulation of cooled air
is desired, select this mode.
2 EXHAUST GAS AUTOMATIC mode − If the outside air
contains harmful substances like exhaust gas (i.e., when
the vehicle running just in front of your vehicle accelerates
rapidly), the system changes automatically from the
OUTSIDE AIR mode (with indicators 2 and 3 on) to
the RECIRCULATED mode (with indicators 1 and 2
on).
3 OUTSIDE AIR mode − The system will take fresh outside
air into the vehicle.
Turning off the air conditioning manually will cancel the
EXHAUST GAS AUTOMATIC mode. If you select the “AUTO”
mode during fan operating, the air conditioning turns on and
the EXHAUST GAS AUTOMATIC mode will operate.
For normal use, it is best to keep the air intake control button
set to OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.
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 4 C
(39 F).
When the air conditioning compressor malfunctions.
When the air conditioning cooler refrigerant decreases.
To change the sensitivity of the sensor switching between
the RECIRCULATED and OUTSIDE AIR in the AUTOMATIC
mode, push the air intake control button until the ”AUTO”
indicator light flashes. The display changes as illustrated
below.
The sensitivity of the sensor can be adjusted only while the
vehicle has stopped.
