ASC (Active Sound Control)
: If equipped
The ASC system is an electronic sound system that generates driving sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers behind the instrument panel. The vehicle’s
response to the driver’s acceleration behavior and shift operations are also
conveyed in sound. When sport mode is selected, the sound conveyed to the
driver will be louder.
