MP3, WMA and AAC files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size using MP3 com-
pression.
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.
AAC is short for Advanced Audio Coding and refers to an audio compression technol-
ogy standard used with MPEG2 and MPEG4.
MP3, WMA and AAC file and media/formats compatibility are limited. ●

MP3, WMA and AAC playback
• When a device containing MP3, WMA or AAC files is connected, all files in the
USB memory device are checked. Once the file check is finished, the first MP3,
WMA or AAC file is played. To make the file check finish more quickly, we recom-
mend that you do not include any files ot her than MP3, WMA or AAC files or cre-
ate any unnecessary folders.
• When a USB memory device is connected and the audio source is changed to USB
memory mode, the USB memory device will start playing the first file in the first
folder. If the same device is removed and reconnected (and the contents have not
been changed), the USB memory device will resume play from the same point in
which it was last used. ●
Extensions
If the file extensions .mp3, .wma and .m4a are used for files other than MP3, WMA
and AAC files, they will be skipped (not played).●
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of at least
128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for MP3, WMA
and AAC files on the market, and depending on the status of the encoding and the
file format, poor sound qualit y or noise at the start of playback may result. In some
cases, playback may not be possible at all.

NOTICE ■
To prevent damage to the USB me mory device or its terminals●
Depending on the size and shape of the USB memory that is connected to the sys-
tem, the console box may not close fully. In this case, do not forcibly close the console
box as this may damage the USB memory or the terminal, etc. ●
Do not leave the USB memory device in the vehicle. The temperature inside the vehi-
cle may become high. ●
Do not push down on or apply unnecessary pressure to the USB memory device
while it is connected. ●
Do not insert foreign objects into the port.

Outside/recirculated air mode ●
When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated ai r mode. This is effective in preventing out-
side air from entering the vehicle interi or. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively. ●
Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature. ■
When the outside temperature is low
The dehumidification function may not operate even when “A/C” is selected. ■
Operation of the air conditioning system in Eco drive mode ●
In the Eco drive mode, the air conditioning sy stem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected ●
To improve air conditioning performa nce, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode ■
Ventilation and air conditioning odors ●
To let fresh air in, set the air conditio ning system to the outside air mode.●
During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. 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 dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.■
