Radio Data System (RDS)
again.
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:
Seek to stations broadcasting
the selected type of
programming.
Receive announcements
concerning local and national
emergencies.
Display messages from radio
stations.
Infotainment System
This system relies on receiving
specific information from these
stations and only works when
the information is available.
In rare cases, a radio station could
broadcast incorrect information
that causes the radio features to
work improperly. If this happens,
contact the radio station.
The RDS system is always on.
When information is broadcast from
the current FM station, the station
name or call letters display on the
audio screen. RDS can provide a
program type (PTY) for current
programming and the name of
the program being broadcasted.
