AIR CONDITIONING AND AUDIO
90The automatic air conditioning automatically maintains the set
temperature.
This air conditioning features automatic fan speed and air flow
control which automatically selects the most suitable fan
speed and air flow to control the temperature. The ignition key
must be in the “ON” position.
You may use manual controls to override the automatic
settings.

(AUTO) button.
Air flow quantity, switching of the diffusers, on-off of the air
conditioning, and switching of the air intake between
RECIRCULATED AIR and OUTSIDE AIR are automatically

operating in automatic mode, the operation corresponding to
the button depressed is set. Other conditions continue to be
adjusted automatically.
2. Press in the
(TEMP) button and hold it until the
desired temperature is displayed.
(TEMP) button is used to set the desired passenger
compartment temperature. The temperature of air delivered to
the passenger compartment will be controlled automatically
according to the setting. The figures on the panel indicate
degrees Fahrenheit or Centigrade.SETTING OPERATION − manual control

The outlets from which air is delivered can be selected
manually by pressing in the appropriate air flow control button.
The function of each button is as follows:
FACE button − Directs air flow at face level.
BI-LEVEL button − Directs air flow at face level and at
floor level front and rear. Except in ventilation, the air to the floor
is slightly warmer than air to the face.
FLOOR button − Directs air flow mostly at floor level
frIf cold adont and rear.
FLOOR / WINDSHIELD button − Directs air flow to the
windshield and front side windows as well as floor level front
and rear.
FRONT WINDSHIELD button − Directs air flow mostly
to the windshield and front side windows.
When this button is depressed while operating in automatic
mode, the air conditioning is set to operate and the OUTSIDE
AIR mode is set.
If you push the “FRONT WINDSHIELD” button once again
while in the FRONT WINDSHIELD mode, the mode then
returns to the last mode used.
CAUTION:
Do not use the FRONT WINDSHIELD 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.

AIR CONDITIONING AND AUDIO
91 If quick heating or cooling is desired −
Push the “TEMP” button on either side and hold it until
“MAX.HOT” or “MAX.COLD” appears on the display.
If manual fan speed control is desired −
The fan speed can be set to your desired speed by pressing
in the appropriate fan speed control button. The higher the fan
speed is, the more air is delivered. Pressing in the “OFF” button
turns off the fan.
To remove exterior windshield frost, use the high speed
setting.
Stopping the fan −
Press in the
(OFF) button.
The fan stops in automatic mode or manual mode.
If manual switching of air intake is desired −
(AIR INTAKE) 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, press in 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
for outside air. If recirculated air is used during heating, the
windows will fog up easier.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.
If the system is used for ventilation, heating in dry weather or
removing the frost or exterior fog on the windshield, press the
air conditioning on − off button once again. This turns off the air
conditioning and improves fuel economy. For year-round
automatic temperature control including cooling and
dehumidifying operation, use the air conditioning.
When the air conditioning compressor does not operate, the
(A / C) button will blink. If the (A / C) button blinks
even when the (A / C) button is pushed again, have the
compressor checked by your nearest Lexus dealer.

is held for 5 seconds. If there is no station on the channel, then
the tuning is only held for 1 second. If the
(SCAN) button
is pushed while listening to a preset station channel, then the
