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 conditio ns.
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 restrictio n of the highest gear, preventing unnec-
essary 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 engi ne braking forces than a higher shift
range.

When in the M position, the gear will not change unless the shift lever or pad-
dle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situation: ●When vehicle speed drops (downshift only).
● When the automatic transmission fluid or engine coolant temperature is
low.
● GS350/GS200t: When automatic transmission fluid temperature is high.
● GS350/GS200t: When the needle of the tachometer is in the red zone
(the range which exceeds the allowable revs of the engine).
In the following situations, the gear will not shift even if the shift lever or paddle
shift switches are operated. ● “Slippery Road. Cannot Shift to Lower Gear.” is displayed on the multi-
information display.
● The vehicle speed is low (upshift only).
