AUTO n (Automatic Volume): With automatic volume, the audio system will adjust automatically to make up for road and wind noise as you drive, by increasing the volume as vehicle speed increases. Set the volume at the desired level. Press this button to select AUTO VOLUME MIN, AUTO VOLUME MED, or AUTO VOLUME MAX. Each higher setting will provide more volume compensation at faster vehicle speeds. To turn automatic volume off, press this button until AUTO VOLUME OFF appears on the display. If your vehicle has the Bose audio system, it includes Bose® AudioPilot® noise compensation technology. When turned on, AudioPilot® continuously adjusts the audio system 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 to your desired level. Turn AudioPilot® on by pressing the automatic volume button until AVOL ON appears on the display. As you increase vehicle speed, the background noise in your vehicle will increase. AudioPilot® will adjust your audio system's output for the background noise it hears. ® To turn AudioPilot® off, press the automatic volume button until AVOL OFF appears on the display. For additional information on AudioPilot®, please visit www.bose.com. MUTE: Press this button to silence the system. Press this button again to turn the sound on.
