AIR CONDITIONING
268If manual onoff of the air conditioning is desired—
Touch
the ”A/C” switch to turn the air conditioning on and touch
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 switch 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” switch will blink. If the indicator of the
”A/C” switch blinks even when the ”A/C” switch is touched
again, have the compressor checked by your nearest Lexus
dealer.

This setting clears the front view more quickly.
If you push the windshield air flow button once again while in
the windshield air flow mode, the mode then returns to the last
mode 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.
(c) Micro dust and pollen filter
This vehicle is equipped with a micro dust and pollen filter
mode. When this mode is activated, air from the vents will
remove pollen on the driver and passengers.
Use this mode to remove pollen quickly carried by the
driver or passengers or through the window in the days
with much pollen.
G21073
Push the micro dust and pollen filter button.
The indicator light comes on and RECIRCULATED AIR mode
is turned on. Air is delivered from the instrument panel vents
to the areas near the driver and passengers to remove pollen
on them. When the interior is purified sufficiently with fresh air
after about 3 minutes, this mode will be turned off automatically
and the indicator light will go out.

270However, when the outside temperature is low, the indicator
light
comes on and the “A/C” switch turns on, but the air intake
control remains the same. When the interior is purified
sufficiently with fresh air after about 1 minute, this mode will be
turned off automatically and the indicator light will go out, but
the “A/C” switch remains on.
When the micro dust and pollen filter is activated, this mode will
be turned off by pushing any of the following buttons:
 Micro dust and pollen filter button
 “A/C” button
 Windshield air flow button
The indicator light will go out when the mode is turned off.
INFORMATION
 Use and push the windshield air flow button to
remove the fog on the windshield in rainy days.
 Fresh air is delivered even when the micro dust and
pollen filter button is turned off.
(d) 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 dashboard
vents and rear vents. (See (e) “Center vents, side vents and
rear vents”.)
 Only 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
control button be set to the OUTSIDE AIR mode to take in
the fresh air and the fan speed selector to any setting except
OFF.

(b) Tone and balance
How good an audio program sounds to you is largely
determined by the mix of the treble, mid
−range, and bass
levels. In fact, different kinds of music and vocal programs
usually sound better with different mixes of treble, mid− range,
and bass.
A good balance of the left and right stereo channels and of the
front and rear sound levels is also important.
Keep in mind that if you are listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.
