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 outside air into the vehicle.

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.
When the air conditioning is ON, 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.

The air conditioning does not work if the outside
temperature is lowered down to around 0 C (32F).
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 ªA/Cº button will blink. If the indicator of
the ªA/Cº button blinks even when the ªA/Cº button is
pushed again, have the compressor checked by your
nearest Lexus dealer.

When you push the ªOUTSIDE TEMPº knob, the
temperature display shows the outside temperature. To
return to the display of the current set temperature, push
the knob again. The temperature display ranges from
