●If the AC charging cable is con-
nected while the “READY” indica-
tor is illuminated, the hybrid
system will stop automatically and
driving will not be possible.
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●Cooling fan sounds may be heard
from near the luggage compart-
ment.
●During charging, sounds may be
heard from near the hybrid battery
(traction battery) in accordance
with the operation of the air condi-
tioning system or “Battery Cooler”.
●During and after charging, the lug-
gage compartment and its sur-
rounding area in which the
onboard traction battery charger is
installed may get warm.

to on, charging will not start even
if the AC charging cable is con-
nected. Also, charging fee may
occur due to connection of the AC
charging cable.
■Using a DC Charger
DC Chargers cannot be used with
this vehicle.
■Capacity reduction of the
hybrid battery (traction battery)
The capacity of the hybrid battery
(traction battery) will decline gradu-
ally when the hybrid battery (traction
battery) is in use. The rate at which
it declines will diff er in accordance
with environmental conditions and
the way in which the vehicle is used.
Observing the following can help
suppress battery capacity decline.
●Avoid parking the vehicle in areas
with a high temperature under
direct sunlight when the hybrid
battery (traction battery) is fully
charged.

AUTO EV/HV mode has switched
to HV mode, turn the power switch
off.
●Use the charging schedule func-
tion as much as possible in order
to fully charge t he hybrid battery
(traction battery) immediately
before starting off. ( P.123)
Things to know before
charging
Make sure to read the fol-
lowing precautions before
charging the hybrid battery
(traction battery).

1142-2. Charging
Also, if the hybrid battery (traction
battery) capacity reduces, the dis-
tance that can be driven in EV mode
or AUTO EV/HV mode decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the hybrid battery (traction bat-
tery) is low after charging
In the following situations, the
remaining charge of the hybrid bat-
tery (traction battery) after charging
completes may be less than normal
in order to protect the system (the
EV driving range after the hybrid
battery [traction battery] is fully
charged may be shorter).
*
●Charging is carried out when the
outside temperature is low or high.
●Charging is carried out immedi-
ately 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 completes, have the vehi-
cle 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
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 “Battery Heater”, etc., reduces
the charging power sent to the
hybrid battery (traction battery), the
charging amount sent to the hybrid
battery (traction battery) may
decrease.
