This system relies upon receiving specific information from these stations and only works when the information is available. In rare cases, a radio station can broadcast incorrect information that can cause the radio features to work improperly. If this happens, contact the radio station. While the radio is tuned to an RDS station, the station name or call letters display instead of the frequency. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast. www.xmradio.com or call 1-800-852-XMXM (9696) or in Canada at www.xmradio.ca or call 1-877-GET-XMSR (438-9677). Playing the Radio PWR (Power): Push this knob to turn the system on and off. VOLUME: Turn this knob to increase or to decrease the volume. 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 MIN (minimum), MED (medium), or MAX (maximum). 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. To turn automatic volume off, press this button until OFF displays. XM™ Satellite Radio Service XM™ is a satellite radio service that is based in the 48 contiguous United States and Canada.
