H12
Information
• Even though charging is possible
with the Engine Start/Stop button in
the ON/START position, for your
safety, start charging when the
Engine Start/Stop button is in the
OFF position and the vehicle shifted
to P (Park). After charging has
started, you can use electrical com-
ponents such as the radio by press-
ing the Engine Start/Stop button to
the ACC or ON position.
• During AC charging, the radio
reception may be bad.
• Moving the shift lever from P (Park)
to R (Reverse)/N (Neutral)/D
(Drive) stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
place the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.8. After charging has started, the
estimated charging time is dis-
played 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 is set,
the estimated charging time is dis-
played as "--".
Information
Depending on the condition and dura-
bility of the high voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the battery may vary.

Charging connector AUTO/LOCK
mode
The charging connector is locked in
the inlet at a different period accord-
ing to which mode is selected.
• LOCK mode : The connector locks
when the charging connector is
plugged into the charging inlet.
• AUTO mode : The connector locks
when charging starts.
For more details, refer to "Charging
Connector AUTO/LOCK Mode" in

Unlock Charging Connector in
Emergency
If the charging connector does not
disconnect due to battery discharge
and failure of the electric wires, open
the hood and slightly pull the emer-
gency cable. The charging connector
will then disconnect .
Precautions for Portable
Charger (ICCB: In-Cable Control
Box)
Use the portable charger that is
certified by HYUNDAI Motors.
Do not try to repair, disassemble,
or adjust the portable charger.
Do not use an extension cord or
adapter.
Stop using immediately when fail-
ure occurs.
Do not touch the plug and charging
connector with wet hands.
Do not touch the terminal part of
the AC charging connector and the
AC charging inlet on the vehicle.
Do not connect the charging con-
nector to voltage that does not
comply with regulations.
Do not use the portable charger if it
is worn out, exposed, or there
exists any type of damage on the
portable charger.
If the ICCB case and AC charging
connector is damaged, cracked, or
the wires are exposed in any way, do
not use the portable charger. Do not let children operate or touch
the portable charger.
Keep the control box free of water.
Keep the AC charging connector or
plug terminal free of foreign sub-
stances.
Do not step on the cable or cord.
Do not pull the cable or cord and
do not twist or bend it.
Do not charge when there is light-
ning.
Do not drop the control box or
place a heavy object on the control
box.
Do not place an object that can
generate high temperatures near
the charger when charging.
Charging with the worn out or dam-
aged household electric outlet can
result in a risk of electric shock. If
you are in doubt to the household
electric outlet condition, have it
checked by a licensed electrician.
Stop using the portable charger
immediately if the household elec-
tric outlet or any components is
overheated or you notice burnt
odors.

Action to be taken when charging stops abruptly
When the high voltage battery does not charge, check the followings:
1. Check the charging setting for the vehicle.
(e.g. When scheduled charging is set, charging is not initiated immediately when the AC charger or portable
charger (ICCB: In-Cable Control Box) is connected.)
2. Check the operation status of AC charger, portable charger.
(Charging Status Indicator Lamp for Portable Charger, refer to "Checking Charging Status" for trickle charge in
this chapter.)
❈Actual method for indicating the charging status may vary in accordance with the charger manufacturer.
3. When the vehicle does not charge and a warning message appears on the cluster, check the corresponding mes-
sage. Refer to "LCD Display Messages", in this chapter.
4. If the vehicle is properly charged when charged with another normally working charger, contact the charger man-
ufacturer.
5. If the vehicle does not charge when charged with another normally working charger, we recommend that you con-
tact an authorized HYUNDAI dealer for inspection.

Special Features
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may
hear a sound from the hybrid battery
system behind the rear seat. If you
apply the accelerator pedal rapidly,
you may hear an unconventional
sound. When you apply the brake
pedal, you may hear a sound from
the regenerative brake system.
When the hybrid system is turned off
or on, you may hear a sound in the
engine compartment. If you depress
the brake pedal repeatedly when the
hybrid system is turned on, you may
hear a sound in the engine compart-
ment. None of these sounds indicate
a problem. These are normal charac-
teristics of hybrid vehicles.If any of following occur, it's a normal
condition if you hear a motor sound
in the engine compartment:
- After turning off the hybrid system,
the brake pedal is released.
- When the hybrid system is turned
off, the brake pedal is applied.
- When the driver door is opened.
When the hybrid system is turned
ON, the gasoline engine may acti-
vate or may not. In this situation, you
may feel a vibration. This does not
indicate a malfunction. When the
" " indicator illuminates, the
hybrid system is ready to begin driv-
ing. Even if the engine is off, you can
operate the vehicle as long as the
" " indicator is illuminated.The hybrid system contains many
electronic components. High volt-
age components, such as cables
and other parts, may emit electro-
magnetic waves. Even when the
electromagnetic cover blocks elec-
tromagnetic emissions, electro-
magnetic waves may have an
effect on electronic devices. When
your vehicle is not used for a long
period of time, the hybrid system
will discharge. You need to drive
the vehicle several times a month.
We recommend driving at least for
1 hour or 10 miles. When the
hybrid battery is discharged, or
when it is impossible to jump start
the vehicle, contact your HYUNDAI
dealer.
