AIR CONDITIONING
250If 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.
If manual on±off of the air conditioning is desired Ð
Push the ªA/Cº 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 (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.

This button allows the air intake to select the OUTSIDE AIR
mode automatically. This is to clean up the front view more
quickly. If you want to return the setting to the
RECIRCULATED
AIR mode, push the air intake control button
once again.
Push the ªA/Cº button for dehumidified heating or cooling. This
setting clears the front view more quickly.
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.
(c) Operating tips
 To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
 Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
 If air flow control is not satisfactory, check the side vents and
rear vents. (See ª(d) Center vents and side ventsº.)
 On humid days, do not blow cold air on the windshield. The
windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
 Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
 On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on the windows.
 When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
be set to the OUTSIDE AIR mode and the fan speed to any
setting except ªOFFº.

and bass.
A good balance of the left and right stereo channels and of the

broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.Each time you push the ªAUDIO´TUNEº knob, the display
