■

During DC charging

●

The current charging condition can be

checked on the multi-information display.

●

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 occurrence 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 tempera-

ture, the specifications of the charger

(stand), etc.

●

It is recommended to avoid frequent DC

charging to prevent a decline in the trac-

tion battery capacity.

●

Quickly move from the DC charging

space for other users after the DC charg-

ing is completed.

●

Depending on the specifications of DC

charger used, charging may be stopped

before fully charged.

●

If DC charging is performed while the

traction battery is extremely cold, such as

in cold weather, steam may come out of

the motor compartment or dew may be

formed on the hood. This is because the

heat, generated while the traction battery

is warmed, causes snow, ice, or frost to

evaporate. This is not a malfunction.
