WARNING
Do not connect or disconnect the USB device
while driving. Doing so can be a distraction.
If distracted you could lose control of your
vehicle and cause an accident or serious
injury.
CAUTION
.Do not force the USB device into the USB
port. Inserting the USB device tilted or
up-side-down into the port may damage
the USB device and the port. Make sure
that the USB device is connected cor-
rectly into the USB port.
. Do not grab the USB port cover (if so
equipped) when pulling the USB device
out of the port. This could damage the
port and the cover.
. Do not leave the USB cable in a place
where it can be pulled unintentionally.
Pulling the cable may break the wire,
USB device or the port. .
To avoid damage and loss of function
when using a USB device, note the
following precautions.
—Do not bend the cable excessively
(1.6 in (40 mm) radius minimum).
—Do not twist the cable excessively
(more than 180 degrees).
—Do not pull or drop the cable.
—Do not hit or press the USB port orUSB device with hands, feet, or
objects.
—Do not store objects with sharpedges in the storage area where the
cable is stored.
—Do not leave the USB device andattached devices in the vehicle com-
partment. When not in use for
extended periods of time, store the
cable and USB device in a clean, dust
free environment at room tempera-
ture and without direct sun exposure.
—Do not use the cable for any other
purposes than its intended use in the
vehicle.
The vehicle is not equipped with a USB device. USB devices should be purchased
separately as necessary.
This system cannot be used to format USB
devices. To format a USB device, use a
personal computer.
In some states/area, the USB device for the
front seats plays only sound without
images for regulatory reasons, even when
the vehicle is parked.
This system supports various USB memory
devices, USB hard drives and iPod
®
players. Some USB devices may not be
supported by this system.
.
Partitioned USB devices may not play
correctly.
. Some characters used in other lan-
guages (Chinese, Japanese, etc.) may
not appear properly in the display.
Using English language characters with
a USB device is recommended.
General notes for USB use:
. The USB device may not function when
the passenger compartment tempera-
ture is extremely high. Lower the
temperature before use.
. During cold weather or rainy days, the
player may malfunction due to humid-
ity. If this occurs, remove the USB
Monitor, climate, audio, phone and voice recognition systems4-59

4-60Monitor, climate, audio, phone and voice recognition systems
device and dehumidify or ventilate the
USB player completely.
. Do not connect a USB device if a
connector, cable or USB port is wet.
Allow the connector, cable, and USB
port to dry completely before connect-
ing the USB device. (Wait for 24 hours
or more until it is dry.) If the connector
and USB port are exposed to fluids
other than water, evaporative residue
may cause a short circuit between the
connector pins and USB port. In this
case, replace the cable and USB port.
Otherwise damage to the USB device
and a loss of function may occur.
. If the cable is damaged (insulation cut,
connectors cracked, contamination
such as liquids, dust, dirt, etc. in the
connectors), do not use the cable.
Replace the cable with a new one.
. Do not put a USB device in a location
where static electricity occurs, electrical
noise is generated or hot air from the
air conditioner blows directly on it.
Doing so may cause the data stored on
the USB device to be corrupted. Notes for iPod®use:
iPod®is a trademark of Apple Inc.,
registered in the U.S. and other countries.
. Improperly plugging in the iPod
®may
cause a checkmark to be displayed on
and off (flickering). Always make sure
that the iPod
®is connected properly.
. An iPod nano®(1st Generation) may
remain in fast forward or rewind mode
if it is connected during a seek opera-
tion. In this case, please manually reset
the iPod
®.

the Play Mode is changed while using
an iPod nano
®(2nd Generation)
. Audiobooks may not play in the same
order as they appear on an iPod
®.
. Large video files cause slow responses
in an iPod
®. The vehicle center display
may momentarily black out, but will
soon recover.
. If an iPod
®automatically selects large
video files while in the shuffle mode,
the vehicle center display may momen- tarily black out, but will soon recover.
Compressed Audio Files (MP3/
WMA/AAC/ATRAC3)
Explanation of terms:
.
MP3 —MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is
the most well known compressed
digital audio file format. This format
allows for near “CD quality”sound, but
at a fraction of the size of normal audio
files. MP3 conversion of an audio track
can reduce the file size by approxi-
mately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually
no perceptible loss in quality. The
compression reduces certain parts of
sound that seem inaudible to most
people.
. WMA —Windows Media Audio (WMA) is
a compressed audio format created by
Microsoft as an alternative to MP3. The
WMA codec offers greater file compres-
sion than the MP3 codec, enabling
storage of more digital audio tracks in
the same amount of space when
compared to MP3s at the same level
of quality.

.AAC/M4A —Advanced Audio Coding
(AAC) is a lossy audio compression
format. Audio files that have been
encoded with AAC are generally smaller
in size and deliver a higher quality of
sound than MP3.
. Bit rate —Bit rate denotes the number
of bits per second used by a digital
music file. The size and quality of a
compressed digital audio file is deter-
mined by the bit rate used when
encoding the file.
. Sampling frequency —Sampling fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
. Multisession —Multisession is one of
the methods for writing data to media.
Writing data once to the media is called
a single session, and writing more than
once is called a multisession.
. ID3/WMA Tag —The ID3/WMA tag is the
part of the encoded MP3 or WMA file
that contains information about the
digital music file such as song title,
artist, album title, encoding bit rate,
track time duration, etc. ID3 tag in-
formation is displayed on the Album/
Artist/Track title line on the display. * Windows®and Windows Media®are

Troubleshooting guide:
SymptomCause and Countermeasure
Cannot play Check if the disc or USB device was inserted correctly.
Check if the disc is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the
player.
If there is a temperature increase error, the player will play correctly after it returns to the normal temperature.
If there is a mixture of music CD files (CD-DA data) and compressed audio files on a CD, only the music CD files (CD-DA data) will be
played.
Files with extensions other than
“.MP3 (.mp3)”,“.WMA (.wma)”, “.AAC (.aac)”,“.M4A (.m4a)”,or “.AA3 (.aa3)”cannot be played. In
addition, the character codes and number of characters for folder names and file names should be in compliance with the
specifications.
Check if the disc or the file is generated in an irregular format. This may occur depending on the variation or the setting of
compressed audio writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the disc or USB device is protected by copyright.
Poor sound quality Check if the disc is scratched or dirty.
It takes a relatively long time before
the music starts playing. If there are many folder or file levels on the disc or USB device, some time may be required before the music starts playing.
Music cuts off or skips The writing software and hardware combination might not match, or the writing speed, writing depth, writing width, etc., might not
match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next song
when playing. If an unsupported compressed audio file has been given a supported extension like .MP3, or when play is prohibited by copyright
protection, the player will skip to the next song.
The songs do not play back in the
desired order. The playback order is the order in which the files were written by the writing software, so the files might not play in the desired order.
Random/Shuffle may be active on the audio system or on a USB device.
