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.

■

°S± mode

●

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.

■

Downshifting restrictions warning buzzer (in the °S± mode)

To help ensure safety and driving performance, downshifting operation may some-

times be restricted. In some circumstances, downshifting may not be possible even

when the shift lever is operated. (The warning buzzer will sound twice.)

■

When driving with the cruise control system (or dynamic radar cruise control sys-

tem)

The engine brake will not operate in the “S” mode, even when downshifting to “7”,

“6”, “5” or “4” (GS460) or “5” or “4” (GS350). (
