G21008
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 AIR 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 AIR 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.

the RECIRCULATED AIR and OUTSIDE AIR in the
AUTOMATIC mode, push the air intake control button and
hold it for a few seconds. The display changes to the one
illustrated below.
The sensitivity of the sensor can be adjusted only while the
vehicle has been stopped.

The sensitivity of the switches is set to be higher toward “HI”
and lower toward “LO”.

When you push any button except the air intake control button,
the above screen goes off.If manual on−off of the air conditioning is desired—
Touch the ”A/C” switch to turn the air conditioning on and touch
it again to turn the air conditioning off. If you turn off the air
conditioning manually, the EXHAUST GAS AUTOMATIC
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 indicator on the A/C switch is off and the EXHAUST
GAS AUTOMATIC indicator light remains 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
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for year−round
automatic temperature control including cooling and
dehumidifying operation.
If the air conditioning compressor does not operate, the
indicator of the ”A/C” switch will blink. If the indicator of the
”A/C” switch blinks even when the ”A/C” switch is touched
again, have the compressor checked by your nearest Lexus
dealer.
