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.
”TREBLE” knob: Use this knob to adjust highpitched 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.

136(c) Automatic sound levelizer
20L111
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.
(e) Your cassette player
When you insert a cassette, the exposed tape should be to the right.
NOTICE
Do not oil any part of the cassette player, and do not insert
anything except a cassette tape into the slot.

137 (f) Your automatic changer
20L006-2
If your Lexus is equipped with an automatic changer, it can play
selected discs or continuously play all the discs set in the magazine.
When you set discs into the magazine, make sure they face the
correct way. If not, the player will display ”Err” and the disc number.
NOTICE
Never try to disassemble or oil any part of the compact disc
player. Do not insert anything except a compact disc into the
magazine.
The player is intended for use with 12 cm (4.7 in.) discs only.

Push this button on the upper side to step up the station band or
on the lower side to step down.
Your radio automatically changes to stereo reception when a stereo
broadcast is received. ”ST” appears on the display. If the signal
becomes weak, the radio reduces the amount of channel separation
to prevent the weak signal from creating noise. If the signal becomes
extremely weak, the radio switches from stereo to mono reception.
In this case, ”ST” disappears from the display.(b) Presetting a station
20L047-1
1. Tune in the desired station.
2. Push one of the station selector buttons ( 16 ) and hold it until
a beep is heard. This sets the station to the button and the button
number ( 16 ) appears on the display.
Each button can store one AM station and two FM stations. To
change the preset station to a different one, follow the same
procedure.
The preset station memory is cancelled when the power source is
interrupted by battery disconnection or a blown fuse.

of the nearest frequency and will stop on reception. Each time you
push the button, the stations will be searched out one after another.
20L0481

player, the player will automatically adapt to it and ”METAL”
appears on the display.
To stop or eject the cassette tape, push the ”EJECT” button.
Autoreverse feature: After the cassette player reaches the end of
a tape, it automatically reverses and begins to play the other side,
regardless of whether the cassette was playing or fast forwarding.
20L050-2

Dolby Noise Reduction* feature: If you are listening to a tape that
was recorded with Dolby* B or C Noise Reduction, push the button
by the doubleD symbol until the appropriate symbol appears on the
display.

Dolby C NR mode reduces tape noise by another 10 dB or about 20
dB total. For best sound reproduction, select the same NR mode that
was used to record the tape.
To play a tape recorded without Dolby NR, push the button until the
symbol disappears from the display.
