■ Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine switch mode may
not change or the engine may not start.
● If attempting to restart the engine immediately after turning the engine
switch off, the engine may not start in some cases. After turning the engine
switch off, wait a few seconds before restarting the engine.
■ If the smart key system has been d eactivated in a customized setting
P. 485
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( P. 439)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.

*1: Shifting to the D position allows the system to select a gear suitable for thedriving conditions. Setting the shift lever to the D position is recommended
for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possiblegear ranges, controls engine braking force, and prevents upshifting above
the selected range.
When the shift lever is in the S position, the shift lever or paddle shift
switches (if equipped) can be operated as follows:
The initial shift range in S mode is set automatically to 4 or 5 accord-
ing to vehicle 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.

Shift ranges and their functions
●
The vehicle is allowed to shift up and down to provide the most
suitable gear selection based on your driving situat ion. (e.g. S4:
1 to 4 or, 4 to 1)
● You can choose from 6 levels of engine braking force.
A lower shift range will provide greater engine braking force than
a higher shift range, and the engine speed will also increase.
● You can choose the gear range y ou want for different levels of
acceleration. (e.g. uphill, sporty driving, etc.)
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 restric-
tion of the highest gear, preventing upshifting and enabling the level of
engine braking force to be selected. Upshifting
Downshifting
The selected shift range, from 1 to
5, or D 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.
When a shift range higher than 5 is selected, the shif t range will return
to the normal D position.
When the vehicle comes to a stop, the shift range will return to the
normal D position.

shift switches)

■S mode
●When the shift range is 4 or lower, holding the shift lever toward “+” sets the
shift range to 6.
● To prevent the engine from over-revving, upshifting may automatically
occur.
● To protect the automatic transmission, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ Downshift restriction warning buzzer (S mode or paddle shifting)
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 switches are operated. (A
buzzer will sound twice.)
■ When driving with cruise control or dynamic radar cruise control acti-
vated
When downshifting to 5 or 4 by shifting the shift lever to the S position or pad-
dle shifting (if equipped), cruise control or dynamic radar cruise control will
not be canceled. ( P. 181, 186)
■ If the shift lever cannot be shifted from P
P. 484
■ If the S indicator does not come on or the D indicator is displayed even
after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer immediately.
(In this situation, the transmission will operate in the same manner as when
the shift lever is in D.)
■ AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver input and
the driving situation.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position or paddle shifting cancels the func-
tion.)
WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
