equipped with a Bose
®audio system, it includes Bose
AudioPilot®noise compensation technology. When
turned on, AudioPilot®continuously adjusts the audio
system equalization, to compensate for background
noise, so that your music always sounds the same at the
set volume level.
This feature is most effective at lower radio volume
settings where background noise can affect how well
you hear the music being played through your vehicle’s
audio system. At higher volume settings, where the
music is much louder than the background noise, there
may be little or no adjustments by AudioPilot
®.
To use AudioPilot
®, set the radio volume at a low to
moderate listening level. Begin listening while the vehicle
is stopped with the motor running; turn the AudioPilot
®
on by pressing the AUTO VOL button until AVOL
ON appears on the display. Then, resume driving,
gradually increasing the vehicle speed. You will notice
that your music sounds the same regardless of
background noises; such as road noise, tire hum, or
wind. With the AudioPilot
®turned off, repeat this process
again without adjusting the volume or tone controls.
you will notice that background noise is now audible,
and will prevent you from hearing softer passages of the
music. To turn AudioPilot
®off, press AUTO VOL until
AVOL OFF appears on the display. For additional
information on AudioPilot
®, please visit www.bose.com.
