Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
The RDS feature is available for use only on FM
stations that broadcast RDS information. This
system relies upon receiving specific information
from these stations and only works when the
information is available. While the radio is tuned to
an FM-RDS station, the station name or call letters
appears on the display. 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.

Playing the Radio
(Power/Volume): Press this knob to turn the
O
system on and off.
Turn this knob clockwise or counterclockwise to
increase or decrease the volume.
Speed Compensated Volume (SCV): The radio
has Speed Compensated Volume (SCV). While
SCV is on, the radio volume automatically adjusts
to compensate for road and wind noise as your
speed changes while driving. That way, the volume
level should sound about the same as you
drive. To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio
setup menu.
3. Press the pushbutton under the AUTO VOLUM
(automatic volume) label on the radio display.
4. Press the pushbutton under the desired Speed
Compensated Volume setting (OFF, Low,
Med (medium), or High) to select the level of
radio volume compensation. The display
times out after approximately 10 seconds.
Each higher setting allows for more radio
volume compensation at faster vehicle speeds.
