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 outside air into the vehicle.
If quick circulation of cooled air is desired, push the air
intake control button for RECIRCULATED AIR. The
RECIRCULATED AIR mode indicator light will come on.
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
RECIRCULATED AIR mode is automatically selected.
This is not a malfunction. When the engine coolant
temperature is lowered, the previous mode resumes.
If manual on–off of the air conditioning is desired –
Push the "A/C" button to turn the air conditioning on and
push it again to turn the air conditioning off.
The air conditioning does not work if the outside
temperature is lowered down to around 0_C (32_F).
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" button will blink. If the indicator of
the "A/C" button blinks even when the "A/C" button is
pushed again, have the compressor checked by your
nearest Lexus dealer.
Displaying the outside temperature –
When you push the "OUTSIDE TEMP" 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
–30_C (–22_F) up to 50_C (122_F).
