Information

[Depending on the condition and
durability of the high voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the battery may vary.

[In rare cases, you might hear high
frequency noise (very little beep sound)
outside the car when charging with
400V fast charger that is deteriorated
or has long communication delay.
The high frequency noise can be
generated only when the car tries to
reduce its own electromagnetic waves
to keep fast charging as possible.
So there is no need to worry about this
little noise, because it is the intentional
operation of the car that does not
affect any charging performance or the
vehicle itself at all.
Checking Charging Status
When charging the high voltage battery,
the charge level can be checked from
outside the vehicle.
For more details, refer to ‘Charge
Indicator Lamp for Electric Vehicle’ in
this chapter.
How to Disconnect DC Charger
1. Remove the charging connector
when DC charging is completed, or
after you stop charging using the DC
charger. Refer to each respective DC
charger manual for details about how
to disconnect the charging connector.
2. Make sure to completely close the
charging door.

window of the control box changes
every time you press the button (1).
6. When setting the charge level is
complete, start charging according to
the portable charge procedure.

1. Connect the plug to a household
electric outlet.

2. Check if the power lamp (green)
illuminates on the control box.
3. Depress the brake pedal and apply the
parking brake.
4. Turn OFF all switches, shift to P (Park),
and turn OFF the vehicle.
If charging is initiated without the
gear in P (Park), the charging will start
after the gear is automatically shifted
to P (Park).

5. Open the charging door.
For more details, refer to ‘Electric
charging door’ in this chapter.
Information
If you cannot open the charging door due
to freezing weather, tap lightly or remove
any ice near the charging door. Do not try
to forcibly open the charging door.
6. Open the protection caps of the
charging connector and the charging
plug. Check if there are any foreign
substances or dust.
7. Hold the charging connector handle
and connect it to the vehicle charging
inlet. Push the connector all the way
in. If the charging connector and
charging terminal are not connected
properly, this may cause a fire.

Information
To control the temperature of the high
voltage battery while charging, the air
conditioner is used to cool down the
battery. It may generate noise or vibration
from operation of the air conditioner
compressor and cooling fan, but it is a
normal condition when charging the high
voltage battery. Also, the air conditioner’s
performance may be degraded due to
operation of the cooling system to charge
the high voltage battery. This is a normal
condition.
Information
(YHQWKRXJKFKDUJLQJLVSRVVLEOHZLWK
the Start/Stop button in the ON/START
position, for you safety, start charging
when the Start/Stop button is in the
OFF position and the vehicle shifted to P
(Park). After charging has started, you
can use electrical components such as the
radio by pressing the Start/Stop button to
the START or ON position.
During charging, the gear cannot be
shifted from P (Park) to any other gear.
ONE1Q011058E
10. After charging has started, the
estimated charging time is displayed
on the instrument cluster for about 1
minute.
If you open the driver seat door while
charging, the estimated charging time
is also displayed on the instrument
cluster for about 1 minute. When
scheduled charging or scheduled
air conditioner/heater is set, the
estimated charging time is displayed
as “--” .
Information
Depending on the condition and durability
of the high voltage battery, charger
specifications, and ambient temperature,
the time required for charging the battery
may vary.
Checking Charging Status
When charging the high voltage battery,
the charge level can be checked from
outside the vehicle.
