If the “READY” indicator does not come on
In the event that the “READY” indicator does not come on even after perform-
ing the proper procedures for starting the vehicle, contact your Toyota dealer
immediately.
■ If the hybrid system is malfunctioning
P. 450
■ If the electronic key battery is depleted
P. 413
■ Operation of the “POWER” switch
●When operating the “POWER” switch, one short, firm press is enough. If the
switch is pressed improperly, the hybrid system may not start or the
“POWER” switch mode may not change. It is not necessary to press and
hold the switch.
● If attempting to restart the hybrid system immediately after turning the
“POWER” switch off, the hybrid system may not start in some cases. After
turning the “POWER” switch off, please wait a few seconds before restarting
the hybrid system.
■ If the smart key system has been d eactivated in a customized setting

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 system 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. 431)
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.

Turns EV drive mode on/off
When EV drive mode is turned on,
the EV drive mode indicator 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 [traction
motor]).
EV drive mode
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) is used to drive the vehicle.
This mode allows you to drive in residential areas early in the
morning and late at night, or in indoor parking lots etc. without
concern for noises and exhaust gas emissions.
However, when the vehicle proximity notification system is
active, the vehicle may produce sound.

■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 shor t 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 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. 108)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.

Automatic cancelation of EV drive mode
When driving in EV drive mode, the gas oline engine may automatically restart
in the following situations. When EV drive mode is canceled, a buzzer will
sound and the EV drive mode indicator will flash and go off.
● The hybrid battery (traction battery) becomes low.
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 1.3 miles (2 km). However, depending on vehicle conditions,
there are situations when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery]
level and driving conditions.)
■ Fuel economy
The hybrid system is designed to achieve the best possible fuel economy
during normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
■ Vehicle Proximity Notification System sound
Even when EV drive mode is turned on, the Vehicle Proximity Notification
System may produce a sound. ( P. 72)
WARNING
■Caution while driving
When driving in EV drive mode no engine noise is made. As such, pedestri-
ans, people riding bicycles or other people and vehicles in the surrounding
area may not be aware of the vehicle starting off or approaching them even
if the Vehicle Proximity Notification System is active. Therefore, take extra
care while driving.

Vehicles without a smart key system: While the engine switch
is in the “ON” position, move the shift lever with the brake
pedal depressed.
Vehicles with a smart key system: While the “POWER” switch
is in ON mode, move the shift lever with the brake pedal
depressed.
When shifting from P to another position; from D to R or P; or from R
to P, D or B; ensure that the brake pedal is being depressed and the
vehicle is stationary.

*: To improve fuel efficiency and reduce noises, set the shift lever in the Dposition for normal driving.
Suitable for enhancing the fuel economy, because the torque corre-
sponding to the accelerator pedal depression amount can be gener-
ated more smoothly than it is in normal conditions and the operation
of the air conditioning system (heating/cooling) will be minimized.
Eco drive mode
When Eco drive mode is turned on,
the “ECO MODE” indicator will
come on.
Pressing the Eco drive mode
switch again turns Eco drive mode
off.
