Before charging, always check the following items.
●The parking brake is applied. (P. 386)
●The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interior lights etc. are switched off.
If these light switches are turned ON, then these features will consume
electricity, and charging time will increase.
●The power switch is off. (P. 373)
Before charging, make sure that each part of the charging cable is in
good condition. (P. 136)
■Safety functions
●The hybrid system will not start while the charging cable is attached to the
vehicle, even if the power switch is operated.
●If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving will not be possi-
ble.
●When the charging cable is connected to the vehicle, the shift position can-
not be changed from P to another position.
■During charging
The followings occur, however, it does not indicate a malfunction.
●The charging starting time may differ depending on the state of the vehicle.
●During charging, the sound of the fan may be heard from the onboard trac-
tion battery charger cooling air intake vents. (P. 164)
●During and after charging, the rear seat and its surrounding area in which
the onboard traction battery charger is installed may get warm.
Confirm the following before charging
Inspecting the charging cable

■Capacity reduction of the hybrid battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental conditions and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
●Avoid parking the vehicle in areas with a high temperature under direct sun-
light when the hybrid battery (traction battery) is fully charged.
●Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
●Avoid frequent driving near the top speed for EV driving. (P. 1 0 4 )
●Leave a low level of charge in the hybrid battery (traction battery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
●Use the charging schedule function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting off.
(P. 176)
Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can be driven in EV mode decreases. However, vehicle performance does
not significantly become worse.
■When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in order to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
●Charging is carried out when the outside temperature is low or high
●Charging is carried out immediately after high-load driving or in extreme
heat
When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.
■When the charging amount sent to the hybrid battery (traction battery)
decreases
When the amount of power supplied by the charger is low or operation of the
“Traction Battery Heater”, etc., reduces the charging power sent to the hybrid
battery (traction battery), the charging amount sent to the hybrid battery (trac-
tion battery) may decrease.

WARNING
■Caution when charging
People with implantable cardiac pacemakers or cardiac resynchronization
therapy-pacemakers should not carry out the charging procedure. Ask
someone else to do it.
● Do not approach the charger and charging cable while charging.
Charging procedure may affect the operation of such devices.
● Do not remain in the vehicle during charging.
Charging procedure may affect the operation of such devices.
● Do not enter the vehicle even to take something out of the luggage com-
partment.
Charging procedure may affect the operation of such devices.
■ When the charging cable is connected to the vehicle
Do not operate the shift lever.
In the unlikely event that the charging cable has been damaged, the shift
position may change from P to another position and the vehicle could move,
possibly leading to an accident.
NOTICE
■ Precautions when handling charging cable
Make sure to observe the following precautions. Failure to observe these
precautions may result in damage to the charging cable and charging inlet.
● Insert the charging connector straight into the charging inlet.
● After inserting the charging connector, 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 charging cable.
● Before removing the charging connector, make sure that it is unlocked.
( P. 171)
● After removing the charging cable, promptly return it to its proper location.
● After removing the charging connector, securely install the charging inlet
cap.

NOTICE
■Onboard traction battery charger cooling air intake vents
● Do not block the air intake vents with seat covers or luggage
● If the air intake vents are clogged with dust, clean them with a vacuum
cleaner
● Do not allow water or foreign matter to enter the air intake vents
● Do not spill large amounts of water near the air intake vents
If water is spilled, have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer and do not
charge the hybrid battery (traction battery) before the inspection.
The grilles under the rear seats are the
cooling air intake vents for the onboard
traction battery charger installed under
the seats.
Make sure to observe the following pre-
cautions regarding the cooling air intake
vents. Failure to observe these precau-
tions may result in a charging system
malfunction.

Use a string, etc. to hang the CCID
(Charging Circuit Interrupting
Device) on a hook or equivalent
when a load is applied to the
socket and plug due to the installa-
tion height of the socket.
The CCID (Charging Circuit Inter-
rupting Device) can be hung by
using the hole in the back.
Do not attach the CCID (Charging
Circuit Interrupting Device) to the
wall with screws.
This section explains the procedure for charging the hybrid bat-
tery (traction battery) with the equipped charging cable.
