(d) Operating tips
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.
(See ”Center vents”, ”Side vents”, ”Lower vent” and ”Rear
vents”.)
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.
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
left to the OUTSIDE AIR mode and the fan speed control button
be pressed to anywhere except the ”OFF” button.
If following another vehicle on a dusty road, or driving in windy
and dusty conditions, it is recommended that the air intake control
button be temporarily pressed in to the RECIRCULATED AIR
mode, which will close off the outside passage and prevent
outside air and dust from entering the vehicle interior.

Using your audio system: some basics
This section describes some of the basic features of the Lexus audio
system. Some information may not pertain to your system.
Your audio system works when the ignition key is in the ”ACC” or
”ON” position.
NOTICE
To prevent the battery from being discharged, do not leave the
car audio on longer than necessary when the engine is not
running.
(a) Turning the system on and off
20L002-1
Push this knob to turn the audio system on and off. Turn this
knob to adjust the volume.
The system turns on in the last mode used.
20L042-2
Push ”AM”, ”FM1/2”, ”TAPE” or ”CD” to turn on that mode.
The selected mode turns on directly.
Push these buttons if you want to switch from one mode to another.
If the tape or disc is not set, the cassette player or compact disc player
does not turn on.
You can turn off the cassette player by ejecting the cassette tape. If
the audio system was previously off, then the entire audio system
will be turned off when you eject the cassette tape. If another
function was previously playing, it will come on again.

20L043
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.
20L044-2
”BASS” knob: Use this knob to adjust lowpitched tones.
”MID” knob: Use this knob to adjust midpitched tones.

”BALANCE” knob: Use this knob to adjust the sound balance
between the right and left speakers.
”FADER” knob: Use this knob to adjust the sound balance between
the front and rear speakers.

When the audio sound becomes difficult to be heard due to road
noise, wind noise, etc. during driving, the system adjusts to the
optimum volume and tone quality according to the noise level.(d) Your radio antenna
The wire antenna is mounted inside the rear window.
NOTICE
When cleaning the inside of the rear window, be careful not
to scratch or damage the wire antenna.
Putting a window tint (especially, conductive or metallic type)
on the rear window may affect the reception of radio. For the
installation of the window tint, consult with your Lexus
dealer.

anything except a cassette tape into the slot.
