■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

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. 537)
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.

Driving
■S mode
●When the shift range is 7 or lower, holding the shift lever toward “+” sets the
shift range to 8.
● 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.)
■ Deactivation of power mode
Power mode will be canceled if the engine is turned off after driving in power
mode.
■ 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 because cruise control or dynamic
radar cruise control will not be canceled.
● While driving in S mode, downshifting to 7, 6, 5 or 4. ( P. 236)
● When switching the driving mode to power mode while driving in D.
(P. 234)
■ 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 the
“ON” position (vehicles without a smart key system) or IGNITION ON mode
(vehicles with a smart key system) and the brake pedal is being depressed.

■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 with your foot on the brake pedal, there
may be a problem with the shift lock system. Have the vehicle inspected by
your Toyota dealer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to the “LOCK” position (vehicles without a smart
key system) or off (vehicles with a smart key system).
Depress the brake pedal.
● 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”.
Pry the cover up with a flathead
screwdriver or equivalent tool.
To prevent damage to the cover,
cover the tip of the screwdriver with a
rag.
Press the shift lock override button.
The shift lever can be shifted while
the button is pressed.

■If the beep sounds continuously when the shift lever is shifted from P
(vehicles with an AUTO ACCESS SEAT)
The AUTO ACCESS SEAT may not be locked in place.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
■ If “S” does not come on even afte r shifting the shift lever to S
This may indicate a malfunction in the automatic transaxle system. Have the
vehicle inspected by your Toyota dealer immediately. (In this situation, the
transaxle 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 perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the function.)
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.
■ To prevent an accident when releasing 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 pedal 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, possibly leading to an accident
resulting in death or serious injury.

■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight switch
off or in the “AUTO” position. (illuminate dimmer than the headlights) Day-
time running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
LED type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight
switch off. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
