• There is excessive background noise, such as wind noise.
■When searching for a track
●A USB memory or iPod must be connected to enable track searching and play-
back. ( →P. 5 0 1 , 5 1 1 )
●When a USB memory or iPod is connected, recognition data is created so tracks
can be searched using voice commands.
●Recognition data is updated under the following conditions:
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. ( →P. 3 6 1 )
●While the recognition data is being created or being updated, a track search can-
not be performed using a voice command.
●While “Play Music” is displayed in the “Shortcut Menu” screen, say “Play Music” to
display the music screen from which searching for a track using a voice command
can be performed.
●When “Play Music” is dimmed in the “Shortcut Menu” screen, it is not possible to
search for a track using a voice command. In this situation, reduce the amount of
music data in the USB memory or iPod and update the recognition data to enable
searching by voice command.

■Reception sensitivity
●Cargo loaded on the roof luggage carrier, especially metal objects, may adversely
affect the reception of XM® Satellite Radio.
●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 inside the rear window.

Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle body,
wheel wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
