Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions. As a result, the following may occur.
Immediately after is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
Cool air may flow to the area around the upper body when the heater is
on.
Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used for an
extended period.
Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched in
accordance with the temperature setting and the inside temperature.
Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode
in situations where the windows need to be defogged.
When the outside air temperature approaches 0C (32F)
The air conditioning system may not operate even when is pressed.
When the indicator light on flashes
Press and turn off the air conditioning system before turning it on
once more. There may be a problem in the air conditioning system if the
indicator light continues to flash. Turn the air conditioning system off and

Automatic mode for air intake control (IS250 only)
In automatic mode, the system detects exhaust gas and other pollutants and
automatically switches between outside air and recirculated air modes.
Pollen removal mode
In order to prevent the windshield from fogging up when the outside air
is cold, the following may occur.
• Outside air mode does not switch to .
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
Air conditioning odors
During use, various odors from inside and outside the vehicle may enter
into and accumulate 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 delayed for a short period of
time immediately after the air conditioning system is started in auto-
matic mode.
CAUTION
To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, blocking
your vision.
NOTICE
To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

When the outside rear view mirror defoggers are on
Do not touch the outside surface of the rear view mirror, as it can become
very hot and burn you.
These features are used to defog the rear window, and to remove rain-
drops, dew and frost from the outside rear view mirrors.
With navigation system
Owners of models equipped with a navigation system should refer to
the “Navigation System Owner's Manual”.

IS250/220d/200d_EE
EON (Enhanced Other Network) system (for traffic announcement func-
tion)
If the RDS station (with EON data) you are listening to is not broadcasting a
traffic information program and the audio system is in the TA (traffic
announcement) mode, the radio will be switched automatically to a station
broadcasting a traffic information program in the EON AF list when traffic
information begins.
When the battery is disconnected
Station presets are erased.
Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the
continually changing position of the antenna, differences in signal
strength and surrounding objects, such as trains, transmitters, etc.
When is used, automatic station selection and automatic register-
ing of stations may not be possible.
The radio antenna is mounted inside the rear window. To maintain clear
radio reception, do not attach metallic window tinting or other metallic
objects to the antenna wire mounted inside the rear window.
Digital Audio Broadcast (DAB) radio
The optional radio antenna and tuner are necessary for the use of Digital
Audio Broadcast (DAB) radio.

MP3 and WMA files
MP3 (MPEG Audio LAYER3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by
using MP3 compression.
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.
There is a limit to the MP3 and WMA file standards and to the media/for-
mats recorded by them that can be used.
MP3 file compatibility
• Compatible standards
MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)

MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc
are first checked. Once the file check is finished, the first MP3 or WMA
file is played. To make the file check finish more quickly, we recommend
you do not write in any files other than MP3 or WMA files or create any
unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data
cannot be played.
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be mistakenly recognized and played as MP3 and
WMA files. This may result in large amounts of interference and damage
to the speakers.
Playback
• To play MP3 file with steady sound quality, we recommend a fixed bit
rate of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances,
depending on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for
MP3 and WMA 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.
• When files other than MP3 or WMA files are recorded on a disc, it
may take more time to recognize the disc and in some cases, playback
may not be possible at all.
• Microsoft, Windows, and Windows Media are registered trademarks
of Microsoft Corporation in the U.S.A. and other countries.
