Driving
*1: Shifting to the D position allows the sys-tem to select a gear suitable for the
driving conditions. Setting the shift lever
to the D position is recommended for
normal driving. You can choose shift
range suitable for your driving situation
by operating the paddle shift switches.
*2: Selecting shift ranges using S mode restricts the upper li mit of the possible
gear ranges, controls engine braking
force, and prevents unnecessary
upshifting.
■When driving with 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 be acti-
vated because dynamic radar cruise con-
trol with full-speed range will not be
canceled.
●While driving in the D position or S mode,
downshifting to 7, 6, 5 or 4. ( P.187)
●When switching the driving mode to
sport mode while driving in D position.
( P.202)
■Restraining sudden start (Drive-Start
Control)
 P.129
■AI-SHIFT
The AI-SHIFT automatica lly selects the suit-
able 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 S position or using the paddle shift
cancels the function.)

WARNING
■When driving on slippery road sur-
faces
Do not accelerate or shift gears sud-
denly.
Sudden changes in engine braking may
cause the vehicle to sp in or skid, resulting
in an accident.

1424-2. Driving procedures
While the engine switch is in IGNITION ON mode and the brake pedal
depressed*, shift the shift lever while pushing the shift release button on the shift
knob.
Shift the shift lever while pushing the shift release button on the shift knob.
Shift the shift lever normally.
When shifting the shift lever between P and D, make sure that the vehicle is completely
stopped and the brake pedal is depressed.
*: For the vehicle be able to be shifted from P, the brake pedal must be depressed before the shift release button is pushed. If the shift release button is pushed first, the shift lock
will not be released.
■Shift lock system
The shift lock system is a system to prevent
accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only
when the engine switch is in IGNITION
ON mode the brake pedal is depressed
and the shift release button is pushed.■If the shift lever cannot be shifted from P
First, check whether the brake pedal is
being depressed.
If the shift lever cannot be shifted even
though the brake pedal is depressed and
the shift release button is pushed, there may
be a problem with th e shift lock system.
Have the vehicle inspected by your Lexus
dealer immediately.

Driving
The following steps may be used as an
emergency measure to ensure that the shift
lever can be shifted.
Releasing the shift lock:
1If the parking brake is in manual mode,
set the parking brake. ( P.146)
2 Turn the engine switch off.
3 Depress the brake pedal.
4 Press down and release the cup holder
lid to open.
5 Pry the cover up with a flathead screw-
driver or equivalent tool.
To prevent damage to the cover, cover the
tip of the screwd river with a rag.
6 Press and hold the shift lock override
button and then push the button on the
shift knob.
The shift lever can be shifted while the but-
ton is pressed
 P.202
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.
1 Upshifting
2 Downshifting
WARNING
■To prevent an accident when releas-
ing the shift lock
Before pressing the shift lock override
button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pe dal is accidentally
depressed instead of the brake pedal
when the shift lock override button is
pressed and the shift lever is shifted out
of P, the vehicle may suddenly start, pos-
sibly leading to an accident resulting in
death or serious injury.
Selecting the driving mode
Selecting shift ranges in the D
position

1444-2. Driving procedures
The selected shift range, from D1 to D8,
will be displaye d in the meter.
■Automatic deactivation of shift range
selection in the D position
Shift range selection in the D position will
be deactivated in the following situations:
●The “+” paddle shift switch is held down
for a period of time
●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 posi-
tion other than D
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, 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.)
To enter S mode, shift the shift lever to
S. Shift ranges can be selected by
operating the shift lever or paddle shift
switches, allowing you to drive in the
gear of your choosing. 1
Upshifting
2 Downshifting
The initial shift range in S mode is set
automatically to 4, 5 or 6 according to
vehicle’s speed. However, the initial
shift range may be set to 3 if AI-SHIFT
has operated while the shift lever was
in the D position. ( P.141)
A lower shift range will provide greater
engine braking forces than a higher
shift range.■S mode
●When the shift range is 7 or lower, hold-
ing the shift lever toward “+” sets the shift
range to 8.
●To prevent the engine from over-revving,
upshifting may automatically occur.
●To protect the automatic transmission, a
function is adopted that automatically
selects a higher shift range when the fluid
temperature is high.
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, 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.)
