Audio System
When using the Bluetooth system,
sound comes through the vehicle's
front audio system speakers and
overrides the audio system. Use the
VOL/ 
knob during a call to
change the volume level. The
adjusted volume level remains in
memory for later calls. The system
maintains a minimum volume level.
