Please use as a power supply
for electronic devices that use
less than 120 VAC (power con-
sumption of 1500 W).
■Using the power outlets
Rear of console box
Open the lid.
Luggage compartment
Open the lid.
■When turning the power
outlets on
1 Check that the parking brake
is engaged, and press the
power switch while depress-
ing the brake pedal.
2 Check that the READY indi-
cator is illuminated, and

outlets off
1 Turn the connected devices
off.
2 Press the AC120V switch to
turn the power outlets off.
3 Disconnect each plug from
the power outlet.
4 Close the lid of each power

■Rules/regulations regarding
idling stop
The engine will start automatically to
charge the hybrid battery (traction
battery) if its charge becomes low.
In some municipalities, if the engine
starts while the vehicle is parked or stopped, it may violate local rules or
regulations regarding idling stop and
you may be penalized. Make sure to
check the local rules and regula-
tions before using the power outlets
while the vehicle is parked or
stopped.
■Power outlets
●When connecting a device, make
sure that the to
tal power con-
sumption of all devices connected
to the 120 VAC power outlets is
less than 1500 W. If a device is
connected and the power con-
sumption is exce eded, a protec-
tion circuit will cut the power
supply and the p ower outlets will
not be able to be used.
●Depending on the device to be
used, the current flow may be high
and the initial peak wattage may
exceed 1500 W.
In this case, the protection circuit
may operate, and the power out-
lets may not be able to be used.
●Depending on the connected
device, it may cause interference
with TV and radio broadcasts.
●The voltage of the power outlets
cannot be measured with a com-
mercially available electrical tes-
ter. If it is necessary to check the
voltage, have the vehicle
inspected by your Toyota dealer.
●While a power outlet is being
used, a cooling fan sound may be
heard from near a rear seat. This
does not indicate a malfunction.
■Devices which may not operate
correctly
The following 120 VAC devices may
not operate properly even if their
power consumption is less than
1500 W:
●Devices with high initial peak watt-
age
●Measuring devices that process
precise data
●Devices that require an extremely

stable power supply
●Devices that require a constant
power supply from the power out-
let, such as a device with a timer.
■When the 120 VAC power out-
lets cannot be used
If the AC120V switch is pressed but
the switch indicator does not illumi-
nate, the protection circuit may have
operated.
In this case, perform the appropriate
procedures as follows.
●Disconnect the plug of each
device from the p ower outlets,
check that the total power con-
sumption of all devices to be con-
nected to the power outlets is less
than 1500 W and check that the
devices are not malfunctioning,
reconnect the devices and then
press the AC120V switch again.
●Check the charge of the hybrid
battery (traction battery)
(  P.122). If the charge is low,
shift the shift lever to P, allow the
engine to run to charge the hybrid
battery (traction battery), and then
press the AC120V switch again.
●If the temperature inside the vehi-
cle is high, such as after the vehi-
cle has been park ed in the sun,
use the air conditioning system to
sufficiently ventilate or cool the
interior, and then press the
AC120V switch again.
●If the vehicle has been stopped in
a cold area, to pro tect the hybrid
battery (traction battery), the
power outlets may not be able to
be used. In this case, drive the
vehicle for a while to warm up the
hybrid battery (traction battery),
and then press the AC120V
switch again.
If the power outlets cannot be used
even after performing the appropri-
ate procedures above, have the
vehicle inspected by your Toyota
dealer.
WARNING
■For safe use
Observe the following precau-
tions.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Do not use devices such as the
following when driving:
• Devices which cannot be prop- erly secured within the vehicle.
• Devices which may distract the driver and be a hinderance to
safe driving, such as a TV, DVD
player, etc.
• Unsecured devices which gen- erate heat, such as a toaster,
microwave, electric heater,
electric kettle, coffee maker,
etc., as they may cause burns
or a fire in the case of sudden
braking or an accident.
• Devices which may fall under the pedals and prevent the
brake pedal from being
depressed.
●Do not use devices which pro-
duce steam while the windows
are closed. Doing so may cause
the windows to fog up, reducing
visibility and making it difficult to
drive safely. Also, the steam
may damage or negatively
affect other devices.
●Do not connect a malfunctioning
device to a power outlet, as
doing so may cause the power
outlets to become inoperable.
●Do not disconnect the plug of a
device while your hands are wet
or insert a pin or other object
into the power ou tlet. Also, if a
liquid or snow is on the power
outlet, dry the outlet before
using it.

The USB charging ports are
used to supply 2.5A (USB Type-
A) or 3.0A (USB Type-C) of
electricity at 5 V to external
devices. Use the appropriate
terminal for each charging port
type.
The USB charging ports are for
charging only. They are not
designed for data transfer or
other purposes.
Depending on the external
device, it may not charge prop-
erly. Refer to the manual
included with the device before
using a USB charging port.
■Using the USB charging
ports
In the console box
Open the console box lid.
NOTICE
Observe the following precau-
tions.
Failure to do so m ay lead to the
power outlets not operating cor-
rectly or damage to the vehicle or
a connected device.
■To avoid short circuit or mal-
function
●Do not set a device which gen-
erates heat near the interior
components or on a seat. Heat
may cause these parts to melt
or burn.
●Do not use devices which are
sensitive to vibration or heat in
the vehicle.
These devices may malfunction
due to vibration while driving or
heat while the vehicle is parked
in the sun.
●When not using a power outlet,
make sure to close the cover. If
foreign matter or a liquid enters
the power outlet, it may cause a
malfunction or short circuit.
●Do not use a multi-point outlet
adapter as doing so may over-
load the power outlet.
■When the ambie nt tempera-
ture is high
If the temperature inside the vehi-
cle is high, such as after the vehi-
cle has been parked in the sun,
the power outlets may not be able
to be used. Sufficiently ventilate
the interior or use the air condi-
tioning system to c ool the interior
before attempting to use the
power outlets.
■When the ambient tempera-
ture is low
If the vehicle has been stopped in
a cold area, to pro tect the hybrid
battery (traction battery), the
power outlets may not be able to
be used. In this case, drive the
vehicle for a while to warm up the
hybrid battery (traction battery).
■To prevent 12-volt battery dis-
charge
Do not use the pow er outlets lon-
ger than necessary when the
hybrid system is not running.
