■“Traction Battery Cooler”
●When the hybrid battery (traction battery) is above a certain temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Co oler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this s creen, sys-
tem operation becomes possible.
● When charging starts, “Traction Battery Cooler” only operates i f the hybrid
battery (traction battery) temperature is hot.
● The charging indicator is illuminated while “Traction Battery C ooler” is on
standby or operating.
● “Traction Battery Cooler” is implemented for a maximum of approximately
30 minutes. However, when the “Departure” time is set ( P. 154) and there
is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become s horter.
● When there is a small amount of remaining charge in the hybrid battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.
● When the following operations are performed while “Traction Bat tery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.

• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( P. 5 1 8 )
• “Charge Now” is implemented ( P. 163, 172)
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
● When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Batt ery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display ( P. 242). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
● “Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of th e remaining
charge of the hybrid battery (traction battery) increases and d ecreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as ch arging by a
charging equipment. The charging equipment that calculates the fee
according to charging time causes a charging fee.

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. 131)
● 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. 161, 163, 171, 172)
• 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.

■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. 93)
● 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. 154)
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.
