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 smart entry & start system indicator light flashes in yellow
The system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
If the electronic key battery is depleted
P. 505
Operation of the “ENGINE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
press and hold the switch.
If the smart entry & start system has been deactivated in a customized
setting
P. 682

CAUTION
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 START STOP” switch for more than 3 seconds,
or press it briefly 3 times or more in succession. (P. 650)
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. 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.

EV drive mode (hybrid vehicle)
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 drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If
it cannot be turned on, a buzzer will sound.
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 0°C (32°F)
for a long period of time etc.
The gasoline engine is warming up.
In EV drive mode, the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
This mode allows you to drive in residential areas early in the morn-
ing and late at night, or in indoor parking lots etc. without concern
for noises and exhaust gas emissions.
Turns EV drive mode on/off
When EV drive mode is turned
on, the EV drive mode indica-
tor will come on. Pressing the
switch when in EV drive mode
will return the vehicle to normal
driving (using the gasoline
engine and electric motor [trac-
tion motor]).
