Things to know before charging
This vehicle has been designed to allow charging from an external
power source using a charging cabl e for exclusive use with standard
household AC outlets.
However, the vehicle differs greatly from standard household el ectri-
cal goods in the following ways, and incorrect usage could caus e fire
or electric shock, pos sibly leading to death or serious injury.
● The charging operation is designed to operate at 12A continuous ly
for the charge duration (up to 5 hours 10 minutes). ( P. 134)
● Charging can be conducted outdoors.
To charge properly, follow the procedure after reading the expl anation
below. Charging is intended to be carried out by licensed drive rs only
who properly understand the charging procedure.
● Charging should not be carried out by children.
● When charging with a charging equipment, follow the procedures
for using each equipment.
● When charging using a public cha rging facility, check the setting of
the charging timer function. • When the charge schedule is registered, temporarily turn off t he
function or turn “ Charge Now” on. ( P. 164, 166, 174, 175)
• When the charge sche dule is set to ON, charging will not start
even if the charging cable is connected. Also, charging fee may
occur due to connection of the charging cable.
Make sure to read the following precautions before connecting
the charging cable to the vehicle and charging the hybrid batte ry
(traction battery).
Charging precautions

2-2. Charging
Before charging, always check the following items.
● The parking brake is applied. ( P. 349)
● The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interi or 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. 3 3 6 )
Before charging, make sure that each part of the charging cable is in
good condition. ( P. 120)
■Safety functions
●The hybrid system will not start while the charging cable is at tached 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 wi ll 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 malfuncti on.
● 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 cha rging
equipment cooling air intake vents. ( P. 145)
● During and after charging, the rear seat and its surrounding ar ea in which
the charging equipment is installed may get warm.
Confirm the following before charging

■Capacity reduction of the hybr id 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 condition s 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 unde r 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. 95)
● Leave a low level of charge in the hybrid battery (traction bat tery) 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 timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off. ( P. 157)
Also, if the hybrid battery (traction battery) capacity reduces , the distance that
can be driven in EV mode decreases. However, vehicle performanc e 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 or der 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 your Toyota dealer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remainin g 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 charging equipment is low or
operation of the “Traction Battery Heater”, etc., reduces the c harging power
sent to the hybrid battery (traction battery), the charging amo unt sent to the
hybrid battery (traction battery) may decrease.

WARNING
■Caution when charging
People with implantable cardiac pacemakers or cardiac resynchro nization
therapy-pacemakers should not carry out the charging procedure. Ask
someone else to do it.
● Do not approach the charging equipment 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 lugg age 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 obse rve 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.
● Vehicles with smart lid & connector locking system: Before removing the
