●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 Microsof t 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 audi o compression technol-
ogy standard used with MPEG2 and MPEG4.
MP3, WMA and AAC file and media/formats compatibility are limited.

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 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 th e 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 other 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 st art playing the first file in the first
folder. If the same device is removed an d reconnected (and the contents have not
been changed), the USB memory device w ill 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 an d 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 the start of playback may result. In some
cases, playback may not be possible at all.
• Microsoft, Windows, and Windows Media ar e the registered trademarks of Micro-
soft Corporation in the U.S.A. and other countries.

■Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key's re gistered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle.
●The system may not operate correctly if more th an one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door.
●The doors that can recall the air conditioning setting* when unlocked using the smart
access system with push-button start can be changed. For details, contact your Lexus
dealer.
*: The doors that can recall the driving posi tion memory are changed at the same time.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately

lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from enteri ng 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 exceeds 75 °F (24 °C) and the air conditioning system
is on
●In order to reduce the air co nditioning power consumption, the air conditioning system
may switch to recirculated air mode automa tically. This may also reduce fuel consump-
tion.
●Recirculated air mode is selected as a defaul t mode when the engine switch is turned to
IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
