2-1. Driving procedures
■ Shift ranges and their functions
● You can choose from 8 levels (GS460) or 6 levels (GS350) of
engine braking force.
● A lower shift range will provide greater engine braking force than a
higher shift range, and the engine revolutions will also increase.
● If you accelerate while in ranges "1" to "7" (GS460) or "1" to "5"
(GS350), the shift range may automatically range up in accordance
with the vehicle' s speed.
● A higher shift range is automatically selected when the automatic
transmission fluid temperature is high.

■
When the shift range is "6" (GS460) or "4" (GS350) or lower, holding the shift
●
lever toward "+" sets the shift range to "8" (GS460) or "6" (GS350).
To prevent the engine from over-revving, upshifting may automatically occur.
●
