Using your audio system: some basics
The following instructions are for the rear passengers.
Please let the rear passengers read and follow the
instructions when the rear passengers use the rear seat
entertainment system.
This section describes some of the basic features of the rear
seat entertainment system. Some information may not pertain
to your system.
Your audio system adjusts to the optimum volume and tone
quality automatically. While the system is adjusting the audio
sound, the audio sound fades out and then fades in.
The rear seat entertainment system is designed for the rear
passengers to enjoy audio and DVD video separately from the
front audio system.
The rear seat entertainment system can be operated when the
ignition key is in the ACCº or ONº position.
The rear passengers can enjoy all modes (AM and FM radio,
cassette tape player, compact disc player with changer and
DVD player) on the rear seat entertainment system only if a
cassette tape and a compact disc are loaded in the front audio
system. The rear seat entertainment system can play DVD video, audio
CD, video CD, CD text, dts-CD or DVD audio only when a disc
is loaded in the DVD player.
You can enjoy videos and sound when your personal audio
system is connected to the input terminal adapter on the rear
console box. For details, refer to the manufacturer's
instructions.
You can enjoy the rear seat entertainment system with
commercial headphone. See Headphone input jacksº on
page 359 in this Section for details.
You can also enjoy the rear seat entertainment system with a
wireless headphone. The wireless headphone can be used
within rear seat. If the signal becomes weak, the headphone
will mute. For details, refer to the manufacturer's instructions.
With some wireless headphone generally available in the
market, it may be difficult to catch sound properly. Lexus

Car audio/video system operating hints
NOTICE
To ensure correct audio/video system operation:
Be careful not to spill beverages over the system.
Do not put anything other than a cassette tape orCompact Disc into the slot.
Do not put anything other than a DVD video, DVDaudio, video CD, dts-CD and audio CD into the DVDplayer.
The use of a cellular phone inside or near the vehiclemay cause a noise from the speakers of the system
which you are listening to. However, this does notindicate a malfunction.
Radio reception
Usually, a problem with radio reception does not mean there is
a problem with your radio Ð 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.

AUDIO
362Here are some common reception problems that probably do
not indicate a problem with your radio:
FM
Fading
and drifting stations Ð 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 transmitter. They are often accompanied by
distortion.
Multi-path Ð 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 other out, causing a
momentary flutter or loss of reception.
Static and fluttering Ð These occur when signals are
blocked by buildings, trees, or other large objects. Increasing
the bass level may reduce static and fluttering.
Station swapping Ð If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again. AM
Fading Ð AM broadcasts are reflected by the upper
atmosphere Ð especially at night. These reflected signals can
interfere with those received directly from the radio station,
causing
the radio station to sound alternately strong and weak.
Station interference Ð When a reflected signal and a signal
received directly from a radio station are very nearly the same
frequency, they can interfere with each other, making it dif ficult
to hear the broadcast.
Static Ð AM is easily affected by external sources of electrical
noise, such as high tension power lines, lightening, or electrical
motors. This results in static.
Caring for your cassette player and tapes
For the best performance for your cassette player and tapes:
Clean the tape head and other parts regularly.
 A dirty tape head or tape path can decrease sound quality
and tangle your cassette tapes. The easiest way to clean
them is by using a cleaning tape. (A wet type is
recommended.)
Use high-quality cassettes.
 Low-quality cassette tapes can cause many problems,
including poor sound, inconsistent playing speed, and
constant auto-reversing. They can also get stuck or tangled
in the cassette player.
 Do not use a cassette if it has been damaged or tangled or
if its label is peeling off.
