To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range will be down-
shifted to a range that enables engine
braking force that is suitable to driving
conditions. When the “+” paddle shift
switch is operated, the shift range will
be one gear higher than the gear in use
during normal D position driving.
Changing the shift range allows restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.
