ASC (Active Sound Control)
The ASC system can be operated when the
driving mode select switch is in sport mode.
SPORT S mode: Sounds are output from
the rear.
SPORT S+ mode: Sounds are output
from the front and rear.
■ Disabling the ASC system
Press the ASC switch.
The indicator on switch will turn off.
Press the switch again to turn the system
back on.
Even if the indicator is illuminated, when
the driving mode select switch is in Nor-
mal or Eco drive mode, ASC does not
operate.
The ASC system directs certain sounds from the front and rear of the cabin to the vehicle
interior, and harmonizes these sounds with the actual sound of the engine and exhaust in
order to allow the driver to feel acceleration and the state of the engine more strongly.
