If manual switching of air intake is desired —
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 indicator light
will turn off 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 indicator light will
come on.
For normal use, it is best to keep the air intake control button
set to the OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.
To prevent fogging up of the windshield, the air intake mode
may change automatically to the OUTSIDE AIR mode
depending on the condition of the air conditioning system.
For example, when the ambient temperature is low, the air
intake mode may change automatically to the OUTSIDE AIR
mode. This is not a malfunction.
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.
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
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.
