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
