The function supports communication between
the driver and front passenger with passengers
in the rear compartment. When voice amplifica‐
tion to the rear is activated, the signals picked
up by the microphone are amplified and played
back over the speakers in the rear compartment,
depending upon vehicle noise levels. An auto‐
matic adjustment occurs based on speaker vol‐
ume and ambient noise in order to improve
speech intelligibility and maintain the natural‐
ness of speech.
Activate or deactivate the function.
