Changing shift ranges in S mode
To enter S mode, shift the shift lever to the S position. The shift range can
then be selected by operating the "-" and "+" shift paddle switches or the
shift lever. Changing the shift range allows restriction of the upper limit of
the gears to be used, preventing unnecessary upshifting and enabling the
level of engine braking force to be selected.
The initial shift range in S mode is automatically set to 5 or 4 according to
vehicle speed. However, the initial shift range may be set to 3 or 2 if the
AI-SHIFT has operated while the shift lever was in the D position.
