AM-FM Stereo with Compact Disc Player with Radio Data System (RDS) and Automatic Tone Control (If Equipped) AUTO VOL: Your system has a feature called Speed-Compensated Volume (SCV). With SCV, your audio system adjusts automatically to make up for road and wind noise as you drive. Set the volume at the desired level. Press AUTO VOL to adjust the SCV. AVOL will appear on the display. Each time you press AUTO VOL, another volume setting (LOW, MEDIUM, HIGH or OFF) will appear on the display. The volume level should always sound the same to you as you drive. Each volume setting allows for more volume compensation at faster vehicle speeds. NONE will appear on the display if the radio cannot determine the vehicle speed. If you don't want to use SCV, select OFF. Finding a Station Playing the Radio VOL PWR: Press this control to turn the system on and off. Turn this control clockwise to increase volume. Turn it counterclockwise to decrease volume.
