tem is on
●In order to reduce the air conditioning power consumption, the air conditioning
system may switch to recirculated air mode automatically. This may also reduce
fuel consumption.
●Recirculated air mode is selected as a default mode when the “START STOP
ENGINE” <“POWER”> swit ch is turned on.
●It is possible to switch to outside air mode at any time by pressing .

clear radio reception, do not attach metallic window tinting or other metallic
objects to the antenna wire mo unted inside the rear window.

■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 that can be used and to the
media/formats on which the files are recorded.
●MP3 file compatibility
• Compatible standardsMP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)

• Compatible bit rates (compatible with VBR) MPEG1 LAYER3: 32—320 (kbps)
MPEG2 LSF LAYER3: 8—160 (kbps)
• Compatible channel modes: stereo, joint stereo, dual channel and monaural
●WMA file compatibility

●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 may 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 files with steady sound quality, we recommend a fixed bit rate of atleast 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depending 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 possi-
ble at all.
