3-2. Using the air conditioning system and defogger
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
am

bient conditions. As a result, the following may occur.
●The system may switch automatically to recirculated mode when the coolest
temperature setting is selected in summer.
●Immediately after the switch 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 the recirculated air mode is used for an
exte
nded period.
■Window defogger feature
Recirculated air mode may automatically switch to
(outside air) mode in situ -
ations where the windows need to be defogged.
■Outside temperature approaches 32 F (0C).
The air conditioning system ma
y not operate even when is touched.

more. There may be a problem in the air conditioning system if the indicator light
co
ntinues to flash. Turn the air conditioning system off and have it inspected by your

3-3. Using the audio system
■When the battery is disconnected
All preset stations 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.
●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 in side the rear window.

■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) 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
TMAudio) 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/formats
recorded by them that can be used.
●MP3 file compatibility
• Compatible standards 
MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)
• Compatible sampling frequencies 

• Compatible bit rates 
MPEG1 LAYER3: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps)

Media that can be used for MP3 and WMA playback are CD-Rs and CD-RWs.

Interior features
●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 files 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 po ssible in some instances, depend-
ing 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 depend ing 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 the registered trademarks of Microsoft Corporation in th e U.S. and other countries.

CAUTION
■Caution while driving
Do not adjust the display.
Be sure to adjust the display on ly when the vehicle is stopped.
■When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the neigh-
borhood. Do not violate any local traffic rules while performing circling calibration.

Doing this may cause a malfunction of the compass sensor.
■To ensure normal operation of the compass
●Do not perform circling calibration of the compass in a place where the earth's
magnetic field is subject to interference by artificial magnetic fields.
●During calibration, do not operate electr ic systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

■Speech recognition information
The Lexus Link speech recognition systems use speech technology that is designed
t
o understand a wide range of speakers of American English. However, the technol -
ogy may not work as well if a regional or et h
nic accent is encountered. If the speech
recognition system does not work properly, refer to the following.
●The system does not recognize your command properly if noise is preset. Per -
form the following to improve voice command recognition.
• Turn down or off the air conditioning system.
• Slow down to reduce wind noise.
• Close the windows and the moon r
oof to block outside noise.
• Have all occupants be quiet so that the system does not recognize their con -
versation as a command.
●When to speak
Say a command within 5 seconds after the system prompts you to speak.
●How to speak
• Speak forcefully and clearly.
• Speak calmly and naturally.
• The driver should speak while facing forward, and the passenger should s
peak facing the inside rear view mirror.
• Avoid speaking with a rising intonati on.
Use a flat or falling intonation.
●Tips for one-word commands
• The system recognizes only one word a
t a time for personal calling. (There
are some exceptions, such as “Advanced services” and “My number”.)
• When inputting the security codes or v
oice-activated keypad number, you
must say them one digit at a time. When inputting a phone number, the
speech recognition system can recognize 7, 10, and 11-digit numbers as well
as the number 911.

Maintenance and care
■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
r
ear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the wi ndow in strokes running parallel to the
heater wires.
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main -
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
b
rush to apply the foam. Rub in overlappin g circles. Do not apply water. The excel-
lent results are obtained by keep ing
the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Be careful not to splash or spill liquid on the floor.
●Do not get any of the SRS components or wiring in the vehicle interior wet. 
