Audio System
When the HFL is in use, the sound
comes through the vehicle's front
audio system speakers. If the audio
system is in use while operating
either of the HFL buttons or making
a call, the HFL over-rides the audio
system. To change the volume level,
use the audio system volume knob,
or the steering wheel volume
controls.
