Selecting shift ranges in the D position
To drive using temporary shift range selection, operate the “-” pad-
dle 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 gears in the M position
To 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 automati-
cally changed in the following situations:
When vehicle speed drops (downshift only).
When the automatic transmission fluid or engine coolant tem-
perature is low.

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 posi-
tion driving.
If the “-” paddle shift switch is operated when a shift range is selected
while in the D position, 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 indicator
Downshift restrictions 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.)
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. 180, 184)
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 5 6
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 vehi-
cle is on a slippery road, the transmission will automatically shift to 2nd
gear for stopping and starting off.
When the shift lever is in D (paddle
shift switches operated) or in M, an
indicator on the tachometer illuminates
in 3 steps in the case of high engine
speeds to encourage the driver to
upshift.
If the third (red) segment illuminates, a
buzzer will also sound

If the automatic transmission fluid temperature warning message is dis-
played
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 the D posi-
tion. However, operating the “-” paddle shift switch will restrict the func-
tion’s operation. (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.
If the automatic transmission fluid tem-
perature warning message is displayed
while driving, 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
message 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 any authorized Lexus
dealer or repairer, or another duly qual-
ified and equipped professional
