Selecting shift ranges in the D position
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, preventing unnecessary upshifting and enabling the level of
engine braking force to be selected. Higher shift range
Lower shift range
The selected shift range, from 1 to
8, will be displayed in the meter
cluster.
To return to normal D position
driving, the “+” paddle shift switch
must be held down for a period of
time.
■ Selecting a driving mode
The following modes can be sele cted to suit driving conditions
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.
“Sport” mode
(→P. 1 8 0 )
To cancel a mode, press the
same side of the switch again.

A lower shift range will provide greater en gine braking force than a higher shift
range.

Selecting gears in the M positionTo enter M mode, shift the shift lever to the M position. Gears can then be
selected by operating the shift lever or paddle shift switches, allowing you
to drive in the gear of your choosing. Upshifting
Downshifting
The gear changes once every time
the shift lever or paddle shift switch
is operated.
The selected gear, from 1 to 8, will
be displayed in the meter cluster.
When in the M position, the gear will not change unless the shift lever or
paddle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situations:
● When vehicle speed drops (downshift only).
● When the automatic transmission fluid or engine coolant temperature
is low.

Gear functions
*: “M” is also displayed to indicate the shift position.
■When the “-” paddle shift switch is operated in the D position
●When the “-” paddle shift switch is operated 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.
●If the “-” paddle shift switch is operated when in range 6 or above, the shift
range may be lowered by two ranges or more in accordance with the driving
conditions.
■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 in
one shift range
■Rev buzzer
If the engine speed approaches the red zone, a buzzer will sound once to encour-
age the driver to upshift.

■Downshift restrictions warning buzzer
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 or paddle shift switch is operated. (A buzzer will sound twice.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur during shift range selection in the D position, even
when downshifting to range 7, 6, 5 or 4. (→P. 158, 161)
■Automatic deactivation of snow mode and “Sport” mode
If the “ENGINE START STOP” switch is turned OFF after driving in either snow
mode or “Sport” mode, the mode is automatically deactivated.
■If the shift lever cannot be shifted from P
→P. 4 7 5
■If is not displayed after shifting the shift lever to M
●Within a few seconds of turning the “ENGINE START STOP” switch to IGNI-
TION ON mode, the transmission will not go into M mode if the shift lever is
moved to the M position. This is because a system check is being performed. In
this case, wait a moment and then try moving the shift lever to the M position
again.
●If the display does not change to on an occasion other than that
described above, it may indicate a malfunction in the automatic transmission
system. Have your vehicle inspected by your Lexus dealer immediately.
■Automatic gear selection when the vehicle is stopped
●When the vehicle comes to a stop, the transmission will automatically downshift
to allow you to start off in 1st gear.
●When the vehicle is idling at high rpm in order to warm up, and the vehicle is on
a slippery road, the transmission will automatically shift to 2nd gear for stopping
and starting off.

■If the automatic transmission fluid temperature warning message is displayed
■AI-SHIFT
The AI-SHIFT automatically selects the optimal gear according to driver perfor-
mance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” paddle shift switch will restrict the function’s operation. (Shift-
ing 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 vehi-
cle skidding to the side or spinning.
If the automatic transmission fluid tempera-
ture warning message is displayed while driv-
ing, make sure you return to normal D
position driving and reduce speed by easing
off the accelerator pedal. Stop the vehicle in a
safe place, shift the shift lever to the P position
and let the engine idle until the warning mes-
sage goes out.
When the warning message goes out, the
vehicle can be driven again.
If the warning message does not go out after
waiting a while, have your vehicle inspected
by your Lexus dealer.

■Usage in winter time
See “Winter driving tips” for parking brake usage in winter time. (→P. 192)
NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components over-
heating, which may affect braking performance and increase brake wear.
Sets the parking brake*
(Depressing the pedal again
releases the parking brake.)
*: Fully depress the parking
brake pedal with your left
foot while depressing the
