TV TR OTRO UTO SORT mode is introduced. n SORT mode, the changing of brake control characteristics allows the driver to control the vehicle motion more than in STR mode. O OTRO This system supports O driving by applying a load to the accelerator pedal according to an accelerator pedal operation during O mode. Reaction force to the accelerator pedal can be switched in two settings between STR and W. edal feedback force to the accelerator pedal can be set to O, as necessary. (Switch the settings on the V screen.) O pedal control and O drive indicator lamp are interlocked each other to support O driving. or further information on O pedal control, refer to -55, "nfiniti rive ode Selector : System escription".
