SCV (Speed-Compensated Volume): With SCV, your audio system adjusts automatically to make up for road and wind noise as you drive. To get to SCV, push the TUNE/AUDIO button repeatedly until SPEED VOL is displayed. Turn the TUNE/AUDIO button to select OFF, MIN, MED, or MAX. Each higher setting allows for more volume compensation at faster vehicle speeds. Then, as you drive, SCV automatically increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. If you don't want to use SCV, select OFF.
