■When the “-” paddle shift switch is operated with the shift lever in the D position
The shift range is downshifted to a range that enables engine braking force that is suit-
able to driving conditions.
■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the power switch is turned off after driving in
snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●While driving in D or S mode, downshifting to 5 or 4. (→P. 245, 249)
●When switching the driving mode to sport mode while driving in D position. (→P. 2 8 3 )
■If the shift lever cannot be shifted from P

Louder
Lower
When the dial is turned to the lowest
volume, driving sound will be turned off
and the indicator will go off.
■ASC is enabled when
The vehicle is being driven in normal mode or sport mode. (→P. 2 8 3 )
■Situations that may disable the ASC system
The ASC system may be disabled depending on the driving conditions, such as when the
tires slip due to sudden acceleration.
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.
