This section describes  some of  the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR·VOL” to turn the audio system
on and off.
Push “AM”, “FM”, “FM1”, “FM2”, “TAPE”,
“DISC” or “LOAD” to turn on that function
without pushing “PWR·VOL”. To turn on
the cassette or compact disc player, a
cassette or compact disc must be loaded
in the player.
You can turn on each player  by  inserting
a cassette tape or compact disc.
You can turn off each player by ejecting
the cassette tape or  compact disc.  If the
audio system was previously off, then the
entire audio system will be turned off
when you eject the cassette tape or com-
pact disc. If another function was pre-
viously playing, it will  come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM”, “FM1”, “FM2”, “TAPE”,
“DISC” or “LOAD” if the system is already
on but you want to switch from one func-
tion to another. TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
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 differ-
ent mixes of treble, midrange and bass.
Balance
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 vol-
ume of one group of sounds while de-
creasing the volume of another.
YOUR RADIO ANTENNA
To remove an antenna,  carefully  turn it
counterclockwise.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER 
(type 1 and type 2)
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The player will play  from track
1 through the end of the disc. Then  it will
play from track 1 again.
NOTICE
Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything other than com-
pact discs into the slot.

With compact disc changer only—
Push and hold the “” or “” side of the
switch until the disc you want to listen to
is set.
3. “MODE” switch
Push “MODE” switch to select an audio
mode. Each push changes the mode se-
quentially if the desired mode is ready to
use.
To turn the audio system on, push the
“MODE” switch.
To turn the audio system off, push and
hold the “MODE” switch until the system
turns off.NOTICE
To ensure correct audio system op-
erations:
 Be careful not to spill beverages
over the audio system.
 Do not put anything other than a
cassette tape or Compact Disc into
the slot.
 The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio system which you are listening
to. However, this does not indicate
a malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires  can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as your vehicle moves. Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations—Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multi
−path—FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.
Static and fluttering—These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping—If the FM signal you
are listening to is interrupted or weak-
ened, and there is another  strong station
nearby on the FM band, your  radio may
tune  in  the second  station until  the origi-
nal  signal  can be picked up again.
