Using automatic sound
leveliser
During driving, noise in the vehicle changes
according to the driving speed and road con-
ditions. The automatic sound leveliser (ASL)
monitors such varying noise and automatical-
ly increases the volume level, if this noise be-
comes greater. This function controls not only
audio sources, but also the guidance voice of
navigation.
