player/compact disc player 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 igni- tion key is in the ACCº or ONº position. TURNING THE SYSTEM ON AND OFF Push PWR
VVOLº or PWR/VOLº to turn
the audio system on and off. Push AM VFMº or TAPEº to turn on that
function without pushing PWR VVOLº or
PWR/VOLº.
You can turn on the cassette player by in- serting a cassette tape.
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 the radio was
previously on, it will come on again. SWITCHING BETWEEN FUNCTIONS
Push AM VFMº or TAPEº if the system is
already on but you want to switch from
one function to another. TONE AND BALANCE
For details about your system's tone and
balance controls, see the description ofyour own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of the
treble, and bass levels. In fact, different
kinds of m
usic and vocal programs usual-
ly sound better with different mixes of treble 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 lower a manual antenna, carefully
push
it down.
To lower a power antenna, turn off the au-
dio system by pushing PWR-VOLº or
PWR/VOLº, or turn the ignition key toLOCKº.
On some models, the power antenna au-
tomatically retracts when the radio mode
is switched off to turn on the cassette tape
player.
NOTICE
To prevent damage to the antenna, make sure it is retracted before
driving you Toyota through an automatic car wash.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed tape should be to the right.
NOTICE
Do not oil any part of the player and do not insert anything other than
cassette tapes into the slot, or the tape player may be damaged.
YOUR COMPACT DISC PLAYER
When you insert a disc, gently push it in with the label side up. (The player will au-
tomatically eject a disc if the label side is down.) The compact disc player will play
from track 1 through the end of the disc.Then it 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 except a compact disc into the slot.
8 cm (3 in.) compact disc singles
Your compact disc player does not need an adaptor to play compact disc singles.
Compact disc singles are about 8 cm (3
in.) in diameter-smaller than standard discs.
After you eject a compact disc single, do
not insert a standard 12 cm (5 in.) disc un-
til DISCº disappears from the display.
NOTICE
Do not use an adaptor for compact disc singlesÐ it could cause
tracking errors or interfere with the ejection of compact discs.
