Playing the Radio PWR (Power): Push this knob to turn the system on and off. VOL (Volume): Turn this knob clockwise or counterclockwise to increase or to decrease the volume. RCL (Recall): Push this knob to switch the display between the radio station frequency and the time. When the ignition is turned off, push this knob to display the time. For XM™ (if equipped), push the RCL knob while in XM™ mode to retrieve four different categories of information related to the current song or channel: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, push the RCL knob until you see the desired display, then hold the knob until the display flashes. The selected display is now the default. SCV (Speed-Compensated Volume): With SCV, 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 MIN (minimum), MED (medium), or MAX (maximum). 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. To turn SCV off, press this button until OFF displays. 246
