The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is off at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

Plug-in Hybrid Vehicle
The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid elec-
tric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and
the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain dis-
tance until the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and
road conditions. Aggressive driving maneuvers may at times temporarily enable the engine to operate for maximum
power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.

Charging Information
• Normal Charger (Stage-2 type): The plug-in hybrid vehicle is charged by
plugging into a normal charger
installed in your home or a public
charging station. (For further details,
refer to the 'Normal Charge'.) Trickle Charger (Stage-1 type): The
plug-in hybrid vehicle can be
charged by using household elec-
tricity.
The electrical outlet in your home
must comply with regulations and
can safely accommodate the
Voltage / Current (Amps) / Power
(Watts) ratings specified on the
trickle charge.
Charging Time
• Normal Charger (Stage-2 type):
Takes about 2-3 hours at room tem-
perature (Can be charged to 100%.).
Depending on the condition and
durability of the high-voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the high-voltage battery
may vary.

Charging Status
You can monitor the charging status
outside of the vehicle when charging
the high-voltage battery.
Scheduled Charging
(if equipped)
You can set-up a charging sched-ule for your vehicle through the
Blue Link AVN control unit.
Refer to the Multimedia manual or
the Blue Link manual for detailed
information about setting sched-
uled charging.
Scheduled charging can only be done when using a normal charger
or the portable charging cable
(ICCB: In-Cable Control Box).

When scheduled charging is set
and the normal charger or the
portable charging cable (ICCB: In-
Cable Control Box) is connected
for charging, the indicator lamp
blinks (for 3 minutes) to indicate
that scheduled charging is set. When scheduled charging is set,
charging is not initiated immediate-
ly when the normal charger or
portable charging cable (ICCB: In-
Cable Control Box) is connected.
When immediate charging is
required, use the AVN to deacti-
vate the scheduled charge setting.
Charging Precautions
OLFP0Q4057N
■ Normal Charger (Stage-2 type)
Fires caused by dust or water
Do not connect the charging
cable connector plug to the vehi-
cle if there is water or dust on the
charging inlet. Connecting while
there is water or dust on the
charging cable connector and
plug may cause a fire or electric
shock.
WARNING
OLFPQ047737

H7
Comply with the following in orderto prevent electrical shock when
charging:
– Use a waterproof charger
– Make sure to not touch thecharging connector and charging
plug when your hand is wet
– Do not charge when there is lightning
– Do not charge when the charging connector and plug is wet
Touching the charging connec-
tor
Do not to touch the charging con-
nector, charging plug, and the
charging inlet when connecting
the cable to the charger and the
charging inlet on the vehicle.
Doing so may result in electrocu-
tion.WARNING
Interference with electronic med-
ical devices
When using medical electric
devices such as an implantable
cardiac pacemaker, make sure to
ask the medical team and manu-
facturer whether charging your
electric vehicle will impact the
operation of the medical devices.
In some instances, electromag-
netic waves that are generated
from the charger can seriously
impact medical electric devices
such as an implantable cardiac
pacemaker.

Always keep the charging connec-
tor and charging plug in clean and
dry condition. Be sure to keep the
charging cable in a condition
where there is no water or mois-
ture.
Make sure to use the designated charger for charging the vehicle.
Using any other charger may
cause failure.
Before charging the battery, turn the vehicle OFF.
Be careful not to drop the charging connector. The charging connector
can be damaged.
Cooling fan
Do not touch the cooling fan
while vehicle is charging. When
the vehicle is switched OFF
while charging, the cooling fan
inside the motor compartment
may automatically operate.WARNING
Charging cable
Immediately stop charging
when you find abnormal
symptoms (smell, smoke).
Replace the charging cable if
the cable coating is damaged
to prevent electrical shock.
When connecting or removing
the charging cable, make sure
to hold the charging connec-
tor handle and charging plug.
If you pull the cable itself
(without using the handle), the
internal wires may disconnect
or get damaged. This may lead
to electric shock or fire.
WARNING

H9
