●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.

ID3 tags can be added to MP3 files, making it possible to record the track title, artist
name, etc.

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

●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 memory device or its terminals
●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.

Due to natural language speech recognitio n technology, this system enables rec-
ognition of a command when spoken naturally. However, the system cannot rec-
ognize every variation of each command.
In some situations, it is possible to omit the command for the procedure and
directly state the desired operation.
This function is available in English, Spanish and French.

■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Pressing “A/C”
button or selecting “A/C” will dehumidify th e air from the outlets and defog the wind-
shield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Windshield fog detection function
When automatic mode is set, the humidity sensor ( P. 4 3 9 ) d e t e c t s f o g o n t h e w i n d -
shield and controls the air conditioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set to
the recirculated air mode. This is effective in preventing outside air from entering the
vehicle interior. 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 operat e even when “A/C” is pressed or “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.
