(RC350/RC300)
 : If equippedThe ASC system is an electronic sound system that generates engine sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speake rs inside the instrument panel.
The vehicle’s response to the driver’s acceleration behavior and shift opera-
tions are also conveyed in sound.
When sport mode is selected, the sound conveyed to the driver will be louder.
