If the player does not operate, check that the disc surface is not soiled
or damaged. If the disc is O.K., the following two causes are
possible.
Condensation may have occurred on the internal mechanism of
the automatic changer. Open the cover to let the air circulate.
The temperature of the player’s internal mechanism is raised
because of high external temperature. Remove the magazine

149 Radio reception
Usually, the 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, and 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 problems that probably do not
indicate a problem 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
transmitter. They are often accompanied by distortion.
Multipath 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 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 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 AM broadcasts are reflected by the upper atmosphere
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 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 difficult to hear the
broadcast.
Static 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 high performance from 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.)

AIR CONDITIONING AND AUDIO
150Use highquality cassettes:
Lowquality cassette tapes can cause many problems, including
poor sound, inconsistent playing speed, and constant
autoreversing. 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.
Do not leave a cassette in the player if you are not listening to it,
especially if it is hot outside.
Store cassettes in their cases and out of direct sunlight.
Avoid using cassettes with a total playing time longer than 100
minutes (50 minutes per side). The tape used in these cassette is
thin and could get stuck or tangled in the cassette player.Caring for your compact disc player and discs
20L037
Use only compact discs labeled as shown. The player is intended
for use with 12 cm (4.7 in.) discs only.
Extremely high temperature can keep your compact disc player
from working. On hot days, use air conditioning to cool the
vehicle interior before you listen to a disc.
Bumpy roads or other vibrations may make your compact disc
player skip.
If moisture gets into your compact disc player, you may not hear
any sound even though your compact disc player appears to be
working. Remove the magazine from the player and wait until it
dries.

Correct
Wrong
Handle compact discs carefully, especially when you set them
into the magazine. Hold them on the edge and do not bend them.
Avoid getting fingerprints on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or other disc damage could
cause the player to skip or to repeat a section of a track. (To see
a pin hole, hold the disc up to the light.)
20L039
To clean a compact disc: Wipe it with a soft, lintfree cloth that has
been dampened with water. Wipe in a straight line from the center
to the edge of the disc (not in a circle). Do not use a conventional
record cleaner or antistatic device.

A new disc may have rough edges on its inner and outer
perimeter. Remove the rough edges by pressing the side of a
ballpoint pen or pencil against the inner and outer edges of the
disc as shown.
If you continue to play a disc with rough edges, flakes will fall on to
the signal side of the disc and cause sound skipping or other
problems.
CAUTION
Compact disc players use invisible laser beams which could
cause hazardous radiation exposure if directed outside the
unit. Be sure to operate the player correctly as instructed.

CLEANING THE INTERIOR
CAUTION
Be careful not to splash water or spill liquid on the floor.
This may prevent the side airbags from activating
correctly, resulting in serious injury.
Do not wash the vehicle floor with water, or allow water to
get onto the floor when cleaning the vehicle interior or
exterior. Water may get into audio components or other
electrical components above or under the floor carpet (or
mat) and cause a malfunction; and it may cause body
corrosion.
Leather Interior
The selected leather is used in your Lexus. Due to a leather product,
some parts of leather may be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened with
5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all traces
of detergent with it.3. Wipe off the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet may
cause the hardening or shrinking of the leather.
NOTICE
Dirt or sand adhered to the leather may damage the treated
surface and cause it to wear earlier. Remove dirt or sand
using a vacuum cleaner.
If a stain should fail to come out with a neutral detergent,
apply a cleaner that does not contain an organic solvent.
Never use organic substances such as benzine, alcohol or
gasoline, or alkaline or acid solutions for cleaning the leather
as these could cause discoloring.
Use of a nylon brush or synthetic fiber cloth, etc. may scratch
the fine grained surface of the leather.
Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. Try to keep your
upholstery always clean.
Long exposure to direct sunlight may cause the leather
surface to harden and shrink. Keep your vehicle in a shaded
area, especially in the summer.
The interior of your vehicle is apt to heat up on hot summer
days, so avoid placing on the upholstery items made of vinyl
or plastic or containing wax as these tend to stick to leather
when warm.
Improper cleaning of the leather upholstery could result in
discoloration or staining.

Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or lukewarm water then lightly wipe
off any dirt.
NOTICE
Do not use organic substances (solvents, kerosene, alcohol,
gasoline, etc.) or alkaline or acidic solutions. These
chemicals can cause discoloring, staining or peeling of the
surface.
If you use cleaners or polishing agents, make sure their
ingredients do not include the substances mentioned above.
If you use a liquid car freshener, do not spill the liquid onto
the vehicle’s interior surfaces. It may contain the ingredients
mentioned above. Immediately clean any spill using the
method mentioned above.
If you have any questions about the cleaning of your Lexus, your
local Lexus dealer will be pleased to answer them.
