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 conditions.
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 restriction 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 flui d 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).

■Gear Shift Indicator function
●Multi-information display: This function automatically operates during M
mode.
Head-up display (GS350/GS200t): This function automatically operates
during M mode when the ECO Driving Indicator is displayed on the head-
up display. ( →P. 1 4 3 )
Head-up display (GS F): This function automatically operates during M
mode when the tachometer is displayed on the head-up display or when
the head-up rev indicator is displayed on the head-up display. ( →P. 1 4 3 )
●By following the Shift-up indicator and shifting up accordingly, it is possible
to achieve improved fuel economy and reduced exhaust emissions.
●The Gear Shift Indicator does not have a similar function for down-shifting.
●Depending on the driving conditions, the Gear Shift Indicator may not dis-
play the Shift-up indicator while driving in M mode.

■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to other than D
■To protect automatic transmission
When the temperature of the transmission fluid becomes high, protection control is per-
formed temporarily. When “Transmission Fluid Temp High See Owner’s Manual” is dis-
played on the multi-information display, ha ve the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
■Downshifting restrictions warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downsh ifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driving in
snow mode.
■When driving with cruise control, dynamic radar cruise control or dynamic radar
cruise control with full-speed range activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.
●6-speed models: While driving in the D position, downshifting to 5 or 4.
( → P. 329, 341, 353)
●8-speed models: While driving in the D position, downshifting to 7, 6, 5 or 4.
(→ P. 329, 341, 353)
●When switching th e driving mode to sport mode while driving in D position. ( →P. 3 5 6 )
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the engine output may be
restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes M) with the accelerator pedal depressed, a warning message appears on
the multi-information display. ( →P. 5 1 8 )
