●MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.
●Playback
• To play MP3 file with steady sound quality, we recommend a fixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be
possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of
Microsoft Corporation in the U.S.A. and other countries.

■Error messages
DISC CHECK: Indicates that the disc is dirty, damaged or was inserted upsidedown. Clean the disc or insert it correctly.
REGION ERROR: Indicates that the DVD region code is not set properly.
DVD ERROR: Indicates that there is a problem inside the player. Eject the disc. Set the disc again.
If the malfunction still exists, take the vehicle to your Lexus
dealer.
■Before using the remote control (for new vehicle owners)
■Headphones
With some headphones generally available in the market, it may be difficult to catch
signals properly. Lexus recommends the use of Lexus genuine wireless head-
phones.
Please contact your Lexus dealer for further details.
■Vo l u m e
●Adjust the volume when you connect the headphones to the jack. Loud sounds
may have a significant impact on the human body.
●Conversational speech on some DVDs is recorded at a low volume to emphasize
the impact of sound effects. If you adjust the volume assuming that the conversa-
tions represent the maximum volume level that the DVD will play, you may be
startled by louder sound effects or when you change to a different audio source.
Be sure to adjust the volume with this in mind. An insulating sheet is set to prevent the bat-
teries from being discharged. Remove the
insulating sheet before using the remote con-
trol.

■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires or antenna. Use a cloth dampened with luke-
warm water to gently wipe the window clean. Wipe the window in strokes running
parallel to the heater wires or antenna.
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not apply water. The excel-
lent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION

●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid bat-
tery (traction battery) air vents.
Doing so may cause the hybrid battery, electrical components etc. to malfunction
or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
