To drive using temporary shift range selection, operate the “-” paddle shift switch.
The shift range can then be selected by operating the “-” and “+” paddle shift
switches. Changing the shift range allows restriction of the highest gear, prevent-
ing unnecessary upshifting and enabling the level of engine braking force to be
selected.
Upshifting
Downshifting
The selected shift range, from D1 to D6,
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 engine braking forces than a higher shift
range.

To enter M mode, shift the shift lever to M. Gears can then be selected by oper-
ating the shift lever or paddle shift switches, allowing you to drive in the gear of
your choice.
Upshifting
Downshifting
The gear changes once every time the
shift lever or paddle shift switch is oper-
ated.
The selected gear, from M1 to M6, will
be fixed and displayed in the meter.
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 fluid or engine coolant temperature is
low.
●When automatic transmission fluid temperature is high.
●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.
●“1st Gear not available due to slippery road surface” is displayed on the
multi information display.
●The vehicle speed is low (upshift only).

The Gear Shift Indicator display is a guide to help the driver achieve improved
fuel economy and reduced exhaust emissions within limits of engine perfor-
mance.
When not in operation
Shift-up indicator
■Gear Shift Indicator function
●This function automatically operates during M mode.
●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 downshifting.
●Depending on the driving conditions, the Gear Shift Indicator may not dis-
play the Shift-up indicator while driving in M mode.
■When the “-” paddle shift switch is operated with the shift lever in the D position
A shift range will be automatically selected. The highest gear of the first shift range will be
one gear lower than the gear in use during normal D position driving.
■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 a position other than D
■To protect the automatic transmission
“Transmission Fluid High Temperature” is displayed on the multi-information display and
a function is adopted that automatically selects a higher shift range when the fluid tem-
perature is high. Have the vehicle inspected by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.

■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downshifting 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.
■Gear position display on the multi-information display
When Gear positions is selected for a Drive Information screen on the multi-information
display and the shift lever is in the D or M position, the currently selected gear position
will be displayed on the multi-information display. (The display changes according to the
shift lever position and driving conditions.)
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●While driving in the D position, downshifting to 5 or 4. (→P. 225, 229)
●When switching the driving mode to sport mode while driving in D position. (→P. 2 6 3 )
■If the shift lever cannot be shifted from P
→P. 5 2 3
■AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever
to the M position cancels the function.)
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
■Gear Shift Indicator display (if equipped)
For safety, the driver should not look only at the display. Refer to the display when it is
safe to do so while considering actual traffic and road conditions.
Failure to do so may lead to an accident.
