If the hybrid system is stopped with the shift lever in a position other
than P, the “POWER” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that is displayed on t he multi-information display and
then press the “POWER” switch once.
Check that on the multi-information display is off.
■ Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode
with the hybrid system not operating for more than 20 minutes (ACCESSORY
mode) or one hour (ON mode), the “POWER” switch will automatically turn
off. However, this function cannot entirely prevent 12-volt battery discharge.
Do not leave the vehicle with the “POWER” switch in ACCESSORY or ON
mode for long periods of time when the hybrid system is not operating.

■ When the ambient temperature is low, such as during winter driving con-
ditions
When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.

■ If the hybrid system does not start
●The immobilizer system may not have been deactivated. ( P. 82)
Contact your Toyota dealer.
■ Steering lock
After turning the “POWER” switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
“POWER” 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 hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning. ●Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is not securely in the P
position. “SHIFT TO P POSITION TO
START” will be displayed on the multi-
information display.
“STEERING LOCK ACTIVE” will be dis-
played on the multi-information display.

WARNING
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If a hybrid system failure occurs while the vehicle is moving, do not lock or
open the doors until the vehicle reaches a safe and complete stop. Doing so
may cause activation of the steering lock which may lead to an accident,
resulting in death or serious injury.
■ When “CHECK SMART KEY SYSTEM” is displayed on the multi-infor-
mation display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately. Failure to do so may lead to the system operat-
ing abnormally and possibly cause an accident or damage to the vehicle.
■ Stopping the hybrid syst em in an emergency
If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the “POWER” switch for more than 2 seconds, or
press it briefly 3 times or more in succession. ( P. 463)
However, do not touch the “POWER” switch while driving except in an
emergency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.

NOTICE
■To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If is displayed on the multi-information display, the “POWER”
switch is not off. Exit the vehicle after turning the “POWER” switch off.
● Do not stop the hybrid system when the shift lever is in a position other
than P. If the hybrid system is stopped in another shift lever position, the
“POWER” switch will not be turned off but instead be turned to ACCES-
SORY mode. If the vehicle is left in ACCESSORY mode, 12-volt battery
discharge may occur.
■ When starting the hybrid system
●Do not depress the accelerator pedal unnecessarily.
● If the hybrid system becomes difficult to start, have your vehicle checked
by your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact your Toyota dealer immediately.

■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically after a short period of time in order to warm up.
In this case, you will become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illumi-
nated, press the EV drive mode switch before the gasoline engine starts to
switch to EV drive mode.
■ Situations in which EV dri ve mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situati\
ons. If it
cannot be turned on, a buzzer will sound and a message will be shown on the
multi-information display.
● The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
● The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 68
F (20C) for
a long period of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
When the amount of remaining hybrid battery (traction battery) charge dis-
played on the meter or multimedia system is low. ( P. 109)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.

◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the sy stem warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically appli ed to help avoid the collision or
reduce the collision speed.
PCS (Pre-Collision System)
: If equipped
The pre-collision system uses the front sensor to detect vehi-
cles in front of your vehicle. When the system determines that
the possibility of a frontal collisi on with a vehicle is high, a warn-
ing operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the
collision. If the system determin es that the possibility of a fron-
tal collision with a vehicle is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( P. 227)
