■Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function.
Operating the engine switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ When the engine switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Toy-
ota dealer immediately.
■ If the electronic key battery is depleted
P. 507
■ Operation of the engine switch
●When operating the engine switch, one short, firm press is enough. If the
switch is pressed improperly, the engine may not start or the engine switch
mode may not change. It is not necessary to press and hold the switch.
● 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, please wait a few seconds before restarting the engine.
The green indicator light on the engine
switch will flash and a message will be
shown on the multi-information display.
Press the engine switch while turning the
steering wheel left and right.

4-2. Driving procedures
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 the vehicle begins to slide due to engine failure or other circumstances, 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. 533)
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.
NOTICE
■ To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If the indicator on the engine switch is illuminated, the engine switch is not
off. When exiting the vehicle, always check that the engine switch is off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ When starting the engine
●Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction.
Contact your Toyota dealer immediately.

4-2. Driving procedures
*1: Shifting to the D position allows the system to select a gear suitable forthe driving conditions. Setting the shift lever to the D position is recom-
mended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possi-ble gear ranges, controls engine braking forces, and prevents unneces-
sary upshifting.
To enter S mode, shift the shift lever to S. Shift ranges can be selected
by operating the shift lever, allowing you to drive in the shift range of
your choosing. The shift range ca n be selected by the shift lever.
Upshifting
Downshifting
The selected shift range, from 1 to
6, will be displayed on the multi-
information display.
The initial shift range in S mode is
set automatically to 5 or 4 accord-
ing to vehicle speed. However, the
initial shift range may be set to 3 if
the AI-SHIFT has operated while
the shift lever was in the D position.

■Shift ranges and their functions
●Automatically selecting gears bet ween 1 and 6 according to vehi-
cle speed and driving conditions. But, the gear is limited accord-
ing to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than
a higher shift range, and the engine speed will also increase.
■ S mode
●When the shift range is 5 or lower, holding the shift lever toward “+” sets the
shift range to 6.
● To prevent excessive engine speed, a function was adopted that automati-
cally selects a higher shift range before the engine speed becomes too high.
● To protect the automatic transaxle, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■ Downshift restriction wa rning buzzer (S mode)
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 is operated. (A buzzer will sound twice.)
■ When driving with the cr uise control or dynamic radar cruise control
activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and down-
shifting to 5 or 4 because cruise control or dynamic radar cruise control will
not be canceled. ( P. 259, 263)
■ If the shift lever cannot be shifted from P
● P. 584
● Vehicles with AUTO ACCESS SEAT: If the AUTO ACCESS SEAT has not
been locked in place after being stowed, the shift lever cannot be shifted
from P.
For details, refer to “AUTO A CCESS SEAT OWNER’S MANUAL”.

WARNING
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
