nShifting the shift lever
While the “ENGINE START STOP” switch is in IGNITION
ON mode, depress the brake pedal and move the shift lever.

2-1. Driving procedures
Selecting shift ranges in the D position
To drive using temporary shift range selection, operate the “-” shift paddle
switch. The shift range can then be selected by operating the “-” and “+”
shift paddle switches. Changing the shift range allows restriction of the
upper limit of the gears to be used, 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
6, will be displayed in the meter
cluster.
To return to normal D position
driving, the “+” shift paddle switch
must be held down for a period of
time.
nSelecting a driving mode
The following patterns can be selected to suit current driving and
operating conditions.
Power mode
For powerful acceleration
and driving in mountainous
regions.
Normal mode
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.
Press “SNOW” to return to nor-
mal mode.

When driving
nShift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher shift
range.
Shift rangeFunction
6Automatically selecting gears between 1 and 6
according to vehicle speed and driving conditions.
5Automatically selecting gears between 1 and 5
according to vehicle speed and driving conditions.
4Automatically selecting gears between 1 and 4
according to vehicle speed and driving conditions.
3Automatically selecting gears between 1 and 3
according to vehicle speed and driving conditions.
2Automatically selecting gears between 1 and 2
according to vehicle speed and driving conditions.
1Setting the gear at 1.

2-1. Driving procedures
Changing shift ranges in S mode
To enter S mode, shift the shift lever to the S position. The shift range can
then be selected by operating the “-” and “+” shift paddle switches or the
shift lever. Changing the shift range allows restriction of the upper limit of
the gears to be used, 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
6, will be displayed in the meter
cluster.
The initial shift range in S mode is automatically set to 5 or 4 according to
vehicle speed. However, the initial shift range may be set to 3 or 2 if the
AI-SHIFT has operated while the shift lever was in the D position.

When driving
nWhen the “-” shift paddle switch is operated in the D position
When the “-” shift paddle 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.
nAutomatic deactivated of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
lWhen the vehicle comes to a stop
lWhen range 6 is selected and the accelerator pedal is depressed
lIf the accelerator pedal is depressed for more than a certain period of time
nGear position display when driving
The current gear is displayed on the multi-information display. (→P. 1 5 4 )
nDownshifting 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 shift paddle switch is operated. (The warning buzzer will
sound twice.)
nWhen driving with the cruise control system or dynamic radar cruise control sys-
tem
Engine braking will not occur during shift range selection in the D position or S
mode, even when downshifting to range 5 or 4. (→P. 166, 170)
nSnow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned off after driving in snow mode.
nIf the shift lever cannot be shifted from P

2-1. Driving procedures
nIf does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the
vehicle inspected by your Lexus dealer immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
nAI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according to the
driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” shift paddle switch will restrict the function’s operation. (Shift-
ing the shift lever to the S position cancels the function.)
CAUTION
nWhen 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.

Snow mode
The snow mode is used for accel-
erating and driving on slippery
road surfaces, such as on snow.
Push the switch once more to
return to normal mode.
nMaximum downshifting speed
Adhere to the downshifting speeds in the following table in order to prevent over-
revving the engine.

Driving the vehicle with the parking brake set will lead to brake components over-
heating, which may affect braking performance and increase brake wear.
Vehicles with an automatic transmission

(Depressing the pedal again
releases the parking brake.)
*: Fully depress the parking
brake pedal with your left
foot while depressing the
brake pedal with your right
foot.
Vehicles with a manual transmission
