would cause the vehicle to move. When
operating the engine switch, depress the
brake pedal, shift the shift lever to P and
set the parking brake.
ASC (Active Sound Con-
trol)*
The ASC system is an electronic
sound system that generates driv-
ing sound, conveying the kinetic sit-
uations of the vehi cle’s acceleration
and deceleration to the driver
through the speakers behind the
instrument panel. The vehicle’s
response to the driver’s accelera-
tion behavior and shift operations
are also conveyed in sound. When
sport mode is selected, the sound
conveyed to the driver will be
louder.
