■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 gr eater 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 auto matically range up in accordance
with the vehicle’s speed.
■“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).
■Downshifting restrictions warning buzzer (in the “S” mode)
To help ensure safety and driving perfor mance, 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 syst em (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). ( P. 150, 153)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned to ACCESSORY or IGNITION ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”
