Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected type of
programming.
Receive announcements concerning local and
national emergencies.
Display messages from radio stations.
This system relies upon receiving specic information
from these stations and only works when the information
is available. In rare cases, a radio station can broadcast
incorrect information that causes 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.

program type (PTY) for current programming, and
the name of the program being broadcast.
