AUTO VOL (Automatic Volume): With automatic volume, the audio system adjusts automatically to make up for road and wind noise as you drive.

Set the volume at the desired level. Press this button to select LOW, MEDIUM, or HIGH. AVOL displays. Each higher setting allows for more volume compensation at faster vehicle speeds.

Then as you drive, automatic volume increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. NONE displays if the radio cannot determine the vehicle speed. To turn automatic volume off, press this button until OFF displays.
