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. ●

ID3, WMA and AAC tags
ID3 tags can be added to MP3 files, making it possible to record 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 record 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 record 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 or AA C 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.

RX450h_RX450hL _U_OM48F85U 6
Interior features ■
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 automatically.
This may also reduce fuel consumption. ●
Recirculated air mode is selected as a default mode when the power switch is turned to
ON mode. ●
It is possible to switch to outside air mode at any time by pressing the outside/recircu-
lated air mode button. ■
Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function. ■
Fogging up of the windows ●
The windows will easily fog up when the humidity in the vehicle is high. Selecting “A/C”
will dehumidify the air from the outlets and defog the windshield 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. 521) detects fog on the wind-
shield and controls the air cond itioning system to prevent fog.■
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 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 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 performanc e, perform the following operations:
• Adjust the fan speed
• Turn off Eco drive mode
