4-2. Driving procedures
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 downshifted
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
upper than the gear in use during normal D position driving.
Changing the shift range allows restriction of the highest shift gear, preventing
unnecessary upshifting and enabling the level of engine braking force to be
selected.
Upshifting
Downshifting
6-speed models: The selected shift range, from D1 to D6, will be displayed in the
meter.
8-speed models: The selected shift range, from D1 to D8, will be displayed in the
meter.
To return to normal D position driving, the “+” paddle shift switch must be held down
for a period of time.
■
Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher shift
range.
