Ventilation and air conditioning odors ●
To let fresh air in, set the air conditioning system to the outside air mode.●
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.

Reception sensitivity ●
Cargo loaded on the roof luggage carrier, especially metal objects, may
adversely affect the reception of XM ®

It is difficult to maintain perfect radio re ception at all times due to the continually
changing position of the antenna, differences in signal stre ngth and surrounding
objects, such as trains and transmitters.●
The radio antenna is mounted inside the rear spoiler and the rear window. To
maintain clear radio reception, do not attach metallic window tinting or other
metallic objects to the antenna wire mounted inside the rear window.■

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 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 recogniz ed 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 qu ality, we recommend a fixed bit rate of
at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible in some in stances, 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 ma y 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 pos-
sible at all.

MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in the
USB memory device are 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 that you do not include any files other than MP3 or WMA files
or create any unnecessary folders.
• When the USB device is connected and the audio source is changed to USB
memory mode, the USB device will start playing the first file in the first folder.
If the same device is removed and reinserted (and the contents have not been
changed), the USB device will resume play from the same point in which it
was last used.●
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).●
