127 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.

RECIRCULATED and OUTSIDE AIR in the AUTOMATIC
mode, push the air intake control button until you hear a beep.

Each time you push the ”TEMP” button, the sensitivity changes from
”+3” down to ”3”. If you do not operate any button for a few
seconds, 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.
The air conditioning does not work if the outside temperature is
lowered down to around 0C (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 yearround
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.

In the ”TAPE” or ”CD” mode, the applicable functions are
shown in the lowest part of the display. Push the switch just
below to turn on each function.
(b) Tone and balance
How good an audio program sounds to you is largely determined by
the mix of the treble, midrange, and bass levels. In fact, different
kinds of music and vocal programs usually sound better with
different mixes of treble, midrange, 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.
