ASC (Active Sound Control) (GS F)
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.
The ASC system can be operated
when the driving mode select switch is
in the following modes. (P. 335)
SPORT S mode/customized mode
●
(powertrain control is set to
"POWER"): Sounds are output from
the rear.
SPORT S+ mode: When the engine
●
speed is in the low-to-medium
speed range, sounds are output
from the rear. At high engine speeds,
sounds are mainly output from the
front.
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, Eco drive or customized mode
(powertrain control is not set to
"POWER"), ASC does not operate.
Automatic reactivation of ASC system
■
Even after the ASC system has been turned off, turning the engine off and then on again
will automatically reactivate the ASC system.
