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 or
Compact Disc into the slot.
 Do not put anything other than a DVD video, DVD
audio, video CD, dtsCD and audio CD into the DVD
player.
 The use of a cellular phone inside or near the vehicle
may cause a noise from the speakers of the 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 problems that probably do
not indicate a problem with your radio:
FM
Fading and drifting stations − Generally, the ef fective 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.

AUDIO
290AM
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 dif ficult
to hear the broadcast.
Static − AM is easily af fected 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. 
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
cassettes is thin and could get stuck or tangled in the
cassette player.
Caring for your compact disc player, DVD player and discs
 Your compact disc player and DVD player are intended for
use with 12 cm (4.7 in.) discs only.
 Extremely high temperatures can keep your compact disc
player and DVD player from working. On hot days, use the
air conditioning to cool the vehicle interior before you use
the players.
 Bumpy roads or other vibrations may make your compact
disc player and DVD player skip.
 If moisture gets into your compact disc player and DVD
player, the players may not play even though they appear
to be working. Remove the disc from the player and wait
until it dries.
CAUTION
Compact disc players and DVD players use an invisible
laser beam which could cause hazardous radiation
exposure if directed outside the unit. Be sure to operate
the players correctly.

 Correct  Wrong
 Handle compact discs carefully, especially when you are
inserting them. Hold them on the edge and do not bend
them. A void 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.)
 Remove discs from the compact disc player when you are
not listening to them. Store them in their plastic cases away
from moisture, heat, and direct sunlight.

AUDIO
294
To clean a compact disc: Wipe it with a soft, lint−free cloth
that has been dampened with water. Wipe in a straight line
from the center to the edge of the disc (not in circles). Dry it with
another soft, lint− free cloth. Do not use a conventional record
cleaner or anti −static device.

THREEWAY CATALYTICCONVERTERS
Threeway catalytic converters are emission control
devices installed in the exhaust system.
The 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, electric
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.
