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.

AIR CONDITIONING AND AUDIO

20L040
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.

THREEWAY CATALYTIC
CONVERTER
31L0022
Threeway catalytic converters are emission control devices
installed in the exhaust system.
It looks somewhat like a muffler, but its purpose is to reduce
pollutants in the exhaust gas.
CAUTION
Keep people and combustible materials away from the
exhaust pipe while the engine is running. The exhaust gas
is very hot.
Do not drive, idle or park your vehicle over anything that
might burn easily such as grass, leaves, paper or rags.
NOTICE
A large amount of unburned gases flowing into the threeway
catalytic converter may cause it to overheat and create a fire
hazard. To prevent this and other damage, observe the following
precautions:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; running out of
fuel could cause the engine to misfire, creating an excessive
load on the threeway catalytic converter.
Do not allow the engine to run at idle speed for more than 20
minutes.
Avoid racing the engine.
Do not pushstart or pullstart your vehicle.
Do not turn off the ignition while the vehicle is moving.
Keep your engine in good running order. Malfunctions in the
engine electrical system, electronic ignition
system/distributor ignition system or fuel system could cause
an extremely high threeway catalytic converter
temperature.
If the engine becomes difficult to start or stalls frequently,
take your vehicle in for a checkup as soon as possible.
Remember, your Lexus dealer knows your vehicle and its
threeway catalytic converter system best.
