Keep interior noise levels to a minimum. The
system may not recognize voice commands if there is
too much background noise.
A short tone sounds after the system
responds indicating when it is waiting for a voice
command. Wait until the tone and then speak.
Speak clearly in a calm and natural
voice.
When using the in vehicle Bluetooth system, sound
comes through the vehicle's front audio system
speakers and overrides the audio system. Use the
audio system volume knob, during a call, to change the
volume level. The adjusted volume level remains in
memory for later calls. To prevent missed calls, a
minimum volume level is used if the volume is turned

Only one paired cell phone can be connected to
the Bluetooth system at a time.
If multiple paired cell phones are within range of
