Interior features
■Automatic mode for air intake control (IS350 only)
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold,
the following may occur.
• Outside air mode does not switch to .
• The air conditioning syst em operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is off.

■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually
changing position of the antenna, differences in signal strength and surrounding
objects, such as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted in side the rear window.

■Discs that can be used
Discs with the marks shown below can be used.
Playback may not be possible depending on recording format or disc features, or
due to scratches, dirt or deterioration.
■CD player protection feature

ods
CDs may be damaged and may not play properly.

■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.
●MP3 file compatibility
• Compatible standards
MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)
• Compatible sampling frequencies MPEG1 LAYER3: 32, 44.1, 48 (kHz)
MPEG2 LSF LAYER3: 16, 22.05, 24 (kHz)
• Compatible bit rates (compatible with VBR) MPEG1 LAYER3: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps)
MPEG2 LSF LAYER3: 64, 80, 96, 112, 128, 144, 160 (kbps)

3-2. Using the audio system
●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title,
artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
●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 depend ing 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 registered trademarks of
Microsoft Corporation in the U.S.A. and other countries.
