Fading and drifting stations: Generally,
the effective range of FM is about 25
miles (40 km). Once outside this range,
you may notice fading and drifting,
which increase with the distance from
the radio transmitter. They are often ac-
companied by distortion.
Multi-path: FM signals are reflective,
making it possible for 2 signals to reach
the vehicle’s 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 flutter-
ing.
Station swapping: If the FM signal be-
ing listened to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, the radio may
tune in the second station until the orig-
inal signal can be picked up again.Fading: AM broadcasts are reflected by
the upper atmosphere — especially at
night. These reflected signals can inter-
fere with those received directly from
the radio station, causing the radio sta-
tion 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 elec-
trical motors. This results in static.

Handle discs carefully, especially when
inserting them. Hold them on the edge
and do not bend them. Avoid getting
fingerprints on them, particularly on the
shiny side.
Dirt, scratches, 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 players when
not in use. Store them in their plastic
cases away from moisture, heat and
direct sunlight.
To clean a disc: Wipe it with a soft, lint-
free cloth that has been dampened with
water. Wipe in a straight line from the
centre to the edge of the disc (not in cir-
cles). Dry it with another soft, lint-free
cloth. Do not use a conventional record
cleaner or anti-static device.
CD-R/CD-RW discs that have not been
subject to the “finalizing process” (a
process that allows discs to be played
on a conventional CD player) cannot be
played.
It may not be possible to play CD-R/
CD-RW discs recorded on a music CD
recorder or a personal computer
because of disc characteristics,
scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the
unit.
It may not be possible to play discs
recorded on a personal computer
depending on the application settings
and the environment. Record with the
correct format. (For details, contact the
appropriate application manufacturers
of the applications.)
CD-R/CD-RW discs may be damaged
by direct exposure to sunlight, high
temperatures or other storage condi-
tions. The unit may be unable to play
some damaged discs.
If you insert a CD-RW disc into the
player, playback will begin more
slowly than with a conventional CD or
CD-R disc.
Recordings on CD-R/CD-RW cannot
be played using the DDCD (Double
Density CD) system.

MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio
compression standards.
This system can play MP3/WMA/AAC
files on CD-R, CD-RW, DVD-R, DVD-
RW discs and USB memory.
This system can play disc recordings
compatible with ISO 9660 level 1 and
level 2 and with the Romeo and Joliet
file system.
When naming an MP3/WMA/AAC
file, add an appropriate file extension
(.mp3/.wma/.m4a).
This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/
WMA/AAC files respectively. To pre-
vent noise and playback errors, use the
appropriate file extension.
This system can play only the first ses-
sion when using multi-session compati-
ble CDs.
MP3 files are compatible with the ID3
Tag Ver. 1.0, Ver. 1.1, Ver. 2.2 and Ver.
2.3 formats. This system cannot display
disc title, track title and artist name in
other formats.
WMA/AAC files can contain a WMA/
AAC tag that is used in the same way
as an ID3 tag. WMA/AAC tags carry
information such as track title and artist
name.
The emphasis function is available only
when playing MP3/WMA files
recorded at 32, 44.1 and 48 kHz.
This system can play back AAC files
encoded by iTunes.
The sound quality of MP3/WMA files
generally improves with higher bit
rates. In order to achieve a reasonable
level of sound quality, discs recorded
with a bit rate of at least 128 kbps are
recommended.M3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the
audio player.
The player is compatible with VBR
(Variable Bit Rate).
When playing back files recorded as
VBR (Variable Bit Rate) files, the play
time will not be correctly displayed if
the fast forward or reverse operations
are used.
It is not possible to check folders that
do not include MP3/WMA/AAC files.
MP3/WMA/AAC files in folders up to
8 levels deep can be played. However,
the start of playback may be delayed
when using discs containing numerous
levels of folders. For this reason, we
recommend creating discs with no
more than 2 levels of folders.

will say “To restart voice recognition,
push the talk switch.”. Then voice
recognition will be suspended.
The voice recognition prompt can be
set to on or off when “Voice prompts”
is selected. This setting can also be
changed on the “Voice settings”

PERIPHERAL MONITORING SYS-
The shape of the obstacle may prevent
a sensor from detecting it. Pay particu-
lar attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro-
jecting outwards in the direction of
your vehicle
CAUTION
Caution when using the Lexus park-
ing assist-sensor
Observe the following precautions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an accident.
• Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
• Do not attach any accessories within
the sensor range.
Even though sensors which are func-
tioning properly continue to detect
obstacles, never use the Lexus park-
ing assist if one more sensor(s) may
be malfunctioning.
NOTICE
Notes when washing the vehicle
Do not apply intensive bursts of water
or steam to the sensor area.
Doing so may result in the sensor
malfunctioning.
As the parking assist-sensor might be
malfunctioning in the following
cases, have it checked by any autho-
rized Lexus dealer or repairer, or
another duly qualified and equipped
professional.
• The graphic which indicates that an
obstacle has been detected does not
come on and a beep does not sound
even when the Lexus parking assist-
sensor mode is turned on.
• The graphic which indicates that an
obstacle has been detected comes on
despite no obstacle around the vehi-
cle.
• If your vehicle has been involved in
an accident.
• If the graphic which indicates that
an obstacles has been detected
remains on without a beeping sound.
