There is an air intake vent under
the rear seat for cooling the DC/DC
converter.
Blocking the air intake vent may
prevent the plug-in hybrid system
from operating properly.
When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks
off the high voltage current and
NOTICE
■Notice about fuel
●For plug-in hybrid vehicles, fuel
may remain in the tank for a long time and undergo changes in qual-ity depending on the how the vehi-
cle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least 20
L [5.3 gal., 4.4 Imp.gal.] over a 12- month period), as this may affect components of the fuel system or
the gasoline engine.
●If the vehicle has not been refueled
for a certain amount of time and it is possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to ON. If the message is displayed, refuel the vehicle immediately.

NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug-gage. Blocking the air intake vent
may prevent the plug-in hybrid sys- tem from operating properly.
●When dust etc. has accumulated in the air intake vent, clean it with a vacuum cleaner to prevent the vent
from clogging.
●Do not wet or allow foreign sub-
stances to enter the air vent as this may cause a short circuit and dam-age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●A filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to P.536.
●If “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown on the
multi-information display, the air intake vent and filter may be clogged. Refer to P.536 for informa-
tion on how to clean the air intake vent.

procedure, etc. of the AC
charging cable are explained.
WARNING
■When using the AC charging
cable and CCID (Charging Circuit Interrupting Device)
Observe the following precautions.
Failure to do so may cause an unex- pected accident, resulting in death or serious injury.
●Do not attempt to disassemble or repair the AC charging cable, charging connector, plug or CCID
(Charging Circuit Interrupting Device).If a problem arises with the AC
charging cable or the CCID (Charging Circuit Interrupting Device), stop charging immediately
and contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not subject the AC charging cable, charging connector, plug or
CCID (Charging Circuit Interrupting Device) to strong force or impact.
●Do not apply excessive force to the AC charging cable by forcefully folding, twisting, pulling or dragging
the AC charging cable.
●Do not damage the AC charging
cable with sharp objects.
●Do not fold the charging connector
or plug or insert foreign objects into them.
●Do not put the charging connector and plug into water.
●Do not bring the AC charging cable to a high-temperature item such as a heating device.
●Do not apply a load to the AC charging cable and plug-cord (such as wrapping the AC charging cable
around the CCID (Charging Circuit Interrupting Device) and the charging connector).
●Do not use or leave the AC charging cable in situations where a
load is applied to the socket and the plug (such as when the CCID (Charging Circuit Interrupting
Device) is hanging in the air without contacting the ground).
●Mode 3 AC charging cable: Do not use outside the rated voltage (less than 277 V) or rated current (less
than 20 A).
NOTICE
■Precautions when handling AC charging cable
Make sure to observe the following precautions. Failure to observe these precautions may result in damage to
the AC charging cable and AC charging inlet.
●Insert the charging connector straight into the AC charging inlet.
●After inserting the charging connec-tor, do not apply excessive force to or twist the connector. Also, do not
lean on the connector or hang any objects from it.
●Do not step on or trip over the AC charging cable.
●Before removing the charging con-nector, make sure that it is unlocked. ( P.121)
●After removing the AC charging cable, promptly return it to its
proper location.

1242-2. Charging
Connect to an AC 220 V - 240 V
socket with a Residual Current
Circuit-Breaker (RCCB) and a
circuit breaker. Use of a 13A
individual circuit is strongly rec-
ommended to ensure AC
charging cable will operate prop-
erly.
We strongly recommend that you
use an exclusive connection
from the junction box for
charging. If you connect on a
socket that is on a shared circuit,
and other electrical appliances
are used on other sockets on the
same circuit, then the circuit
breaker might trip.*
Ensure that the junction box is

be used
An external power source that
fulfills the following criteria is
necessary for charging this
vehicle. Confirm this before
charging.
WARNING
■Warnings for electrical faults
Make sure to observe the precautions

WARNING
●Connect to an AC 220 V - 240 V socket with a Residual Current Cir-
cuit-Breaker (RCCB) and supplied by a circuit breaker in line with local regulations. Use of an individual cir-
cuit provided with at least 13A is strongly recommended.
●Do not connect the AC charging cable to a multi-socket adaptor, multi-plugs, or conversion plug.
●Connecting the AC charging cable to an extension cord is strictly pro-
hibited. The extension cord may overheat and does not contain a Residual Current Circuit-Breaker
(RCCB). The leakage detection function of the CCID (Charging Circuit Inter-
rupting Device) ( P.112) may not operate correctly.
●Do not connect to a power strip.
●Use of a block heater socket which
fails to meet the requirements is prohibited for charging.
●Make sure to connect the charging connector and AC charging inlet directly. Do not connect a convert-
ing adaptor or extension cord between the charging connector and AC charging inlet.
