If manual switching of air intake is desired
20X023a
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 RECIRCULA TED 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.

When you turn the “TEMP” knob, the sensitivity changes from
“+3” down to “−3”. If you do not operate any button for a few
seconds or if you push a button other than the air intake control
button and temperature control knob, the previous display
returns.
If manual onoff 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. 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 0 C
(32 F), the air conditioning will turn off automatically. At this
time, the indicator on the A/C button is off and the EXHAUST
GAS AUTOMATIC indicator light remains on. However, the
EXHAUST GAS AUTOMA TIC 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” 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.

setting clears the front view more quickly.
Pushing this button once again returns the air flow mode to the
last one used.
CAUTION
Do not use the windshield air flow button during cooled
air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
