The sensitivity of the switches is set to be higher toward “HI”
and lower toward “LO”.
Touch the desired switch on the screen.
When
you push any button except the air intake control button,
the above screen goes off. If 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.

(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.
