ID3, WMA and AAC tags
ID3 tags can be added to MP3 files, making it possible to recor d 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 recor d the
track title and artist name in the same way as with ID3 tags.
AAC tags can be added to AAC files, making it possible to recor d the track
title and artist name in the same way as with ID3 tags.
● MP3, WMA and AAC playback
• When a device containing MP3, WMA and AAC files is connected, all
files in the USB memory device are checked. Once the file check is fin-
ished, the first MP3, WMA and AAC file is played. To make the file check
finish more quickly, we recommend that you do not include any f iles other
than MP3, WMA and AAC files or create 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 pl ay-
ing the first file in the first folder. If the same device is r emoved and
reconnected (and the con- tents have not been changed), the USB mem-
ory 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 fi xed 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 quality or noise at th e start of
playback may result. In some cases, playback may not be possible at all.
• Microsoft, Windows, and Windows Media are the registered trade marks
of Microsoft Corporation in the U.S.A. and other countries.
WARNING
■ While driving
Do not connect a USB memory device or operate the device contro ls.

■Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/cool-
ing capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning perf ormance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
■ Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.

Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ When the outside temperature exceeds 75 F (24 C) and the air condition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing 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 power switch
is turned to the “ON” position (vehicles without a smart key system) or the
power switch is turned to ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pre ssing .
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is pre ssed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
mode.
