2-2. Charging
Electric Vehicle system
Before charging, always check the
following items.
 The parking brake is applied.
( P.254)
 The power switch is turned to
OFF. ( P.243)
 Lights such as the headlights,
emergency flashers and interior
lights, etc., are turned off.
If these light switches are turned on,
then these features will consume elec-
tricity, and charging time will increase.
Before charging, make sure that
each part of the AC charging cable
is in good condition. ( P.106)
■During charging
●The charging starting time may differ
depending on the state of the vehicle, but this does not indicate a malfunc-
tion.
●During charging, sounds may be
heard from near the traction battery in accordance with the operation of the air conditioning system or “Battery
Cooler” ( P.115).
●During and after charging, the motor
compartment and its surrounding 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 conditions,
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 regis- tered, temporarily turn off the function or turn “Charge Now” on. ( P.134)
• When the charging schedule is set to on, charging will not start even if the AC charging cable is connected. Also,
charging fee may occur due to con- nection of the AC charging cable.
■Capacity reduction of the traction battery
The capacity of the traction battery will decline gradually when the traction bat-tery 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 the decline in the traction battery capacity.
●Avoid parking the vehicle in high tem-perature areas, under direct sunlight when the traction battery is fully
charged.
●Avoid accelerating and decelerating
frequently and suddenly.
●Avoid frequent driving at high speed.
●Use the charging schedule function as much as possible in order to fully
charged the traction battery before starting off. ( P.134)
●Avoid frequent DC charging
Also, if the capacity of the traction bat-
tery capacity reduces, the distance that
can be driven decreases. However,
vehicle performance does not signifi-
cantly become worse.
■When the remaining charge of the traction battery is low after charging
In the following situations, the remaining charge of the traction battery after

 P. 1 1 0
■If a message indicating vehicle
error on the DC charger side is dis- played
Even if a message indicating vehicle
error on the DC charger side (ex. vehicle error found, vehicle error occurred, etc.) is displayed, there is no vehicle fault but
possibly a communication error between the DC charger and vehicle. In this case, there may be terminal damage (bad
contact) in the DC charging connector. If there is no error with the vehicle, contact the facility manager of the DC charger.
■During DC charging
●The current charging condition can be checked on the multi-information dis-
play.
●The actual charging time may differ
from that displayed on the DC charger during charging.
●There may be occasions the radio cannot be heard due to noise occur-rence during DC charging
●As the battery approaches full charge, the charging speed will decrease and
it will take longer to complete charging.
●The time to complete charging may change, or charging may stop before reaching the upper limit of the charge
capacity, due to the remaining charge of the traction battery, the outside tem-perature, the specifications of the
charger (stand), etc.
●It is recommended to avoid frequent
DC charging to prevent a decline in the traction battery capacity.
●Quickly move from the DC charging space for other users after the DC charging is completed.
■How to set the DC charging power
