the following items.
 The parking brake is applied.
( P.243)
 The power switch is turned to
OFF. ( P.231)
 Lights such as the headlights,
emergency flashers and inte-
rior lights, etc. are turned off.
If these light switches are turned
on, then these features will con-
sume electricity, and charging time
will increase.
Before charging, make sure that
each part of the AC charging
cable is in good condition.
( P.92)
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●During charging, sounds may be
heard from near the traction bat-
tery in accordance with the opera-
tion of the air conditioning system
or “Battery Cooler” ( P.99).
●During and after charging, the motor compartment and its sur-
rounding area in which the
onboard traction battery charger is
installed may get warm.
●The surface of the CCID
(Charging Circuit Interrupting
Device) may become hot, but this
does not indicate a malfunction.
●Depending on radio wave condi-
tions, interference may be heard
on the radio.
■When charging using a public
charging facility
●When charging using a public
charging facility, check the setting
of the charging schedule function.
• When the charging schedule is registered, temporarily turn off the
function or turn “ Charge Now” on.
(  P. 1 1 9 )
• When the charging schedule is set 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.
■Capacity reduction of the trac-
tion battery
The capacity of the traction battery
will decline gradually when the trac-
tion battery is in use. The rate at
which it declines will differ in accor-
dance with environmental conditions
and the way in which the vehicle is
used. Observing the following can
help suppress the decline in the
traction battery capacity.
●Avoid parking the vehicle in high
temperature areas, under direct
sunlight when the traction battery
is fully charged.
●Avoid accelerating and decelerat-
ing frequently and suddenly.
●Avoid frequent d riving at high
speed.
●Use the charging schedule func-
tion as much as possible in order
to fully charged the traction bat-
tery before starting off. ( P. 1 1 8 )
