Hybrid Vehicle
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the petrol engine and the electric motor for power. The electric
motor is run by a 270V 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 at idle, or when the vehicle is driven by the electric motor with the HEV bat-
tery.
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
•AC Charge :
The plug-in hybrid vehicle is
charged by plugging into a AC
charger installed in your home or a
public charging station. (For further
details, refer to the 'AC Charge'.)Trickle Charge :
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
portable charge.
Charging Time
AC Charge :
Takes approximately 2 hours 15
minutes at room temperature. (Can
be charged to 100%.)
Information
Depending on the condition and dura-
bility of the high voltage battery, charg-
er specifications, and ambient tempera-
ture, the time required for charging the
high voltage battery may vary.

Scheduled Charging
(if equipped)
You can set-up a charging sched-
ule for your vehicle using the AVN
or BlueLink application.
Refer to the Multimedia manual or
the BlueLink manual for detailed
information about setting sched-
uled charging.
Scheduled charging can only be
done when using a AC charger or
the portable charger (ICCB: In-
Cable Control Box). When scheduled charging is set
and the AC charger or the portable
charger (ICCB: In-Cable Control
Box) is connected for charging, the
indicator lamp in the middle blinks
(for 3 minutes) to indicate that
scheduled charging is set.
When scheduled charging is set,
charging is not initiated immediate-
ly when the AC charger or portable
charger (ICCB: In-Cable Control
Box) is connected. When immedi-
ate charging is required, use the
infotainment system to deactivate
the scheduled charge setting or
press scheduled charging deacti-
vation ( ) button. If you press the scheduled charg-
ing deactivation ( ) button to
immediately charge the battery,
charging must be initiated 3 min-
utes after the charging cable has
been connected.
When you press the scheduled
charging deactivation ( ) button
for immediate charging, the sched-
uled charge setting is not com-
pletely deactivated. If you need to
completely deactivate the sched-
uled charge setting, use the AVN
to finalize the deactivation.
Refer to "Normal Charge or Trickle
Charge" for details about connecting
the AC charger and the portable
charger (ICCB: In-Cable Control Box).

Immediately stop charging
when you find abnormal
symptoms (odor, 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
Always keep the charging con-
nector and charging plug in
clean and dry condition. Be
sure to keep the charging
cable in a condition where
there is no water or moisture.
Make sure to use the designat-
ed charger for charging the
electric vehicle. Using any
other charger may cause fail-
ure.
Before charging the battery,
turn the vehicle OFF.
When the vehicle is switched
OFF whilst charging, the cool-
ing fan inside the motor com-
partment may automatically
operate. Do not touch the cool-
ing fan whilst charging.
Be careful not to drop the
charging connector. The
charging connector can be
damaged.
CAUTION

H127. Check if the charging indicator
light of the high voltage battery on
the instrument cluster is turned
ON. Charging is not done when
the charging indicator lamp is
OFF.
When the charging connector and
charging plug are not connected
properly, reconnect the charging
cable to charge.
Information
• Even though charging is possible
with the ignition switch in the
ON/START position, for your safe-
ty, start charging when the ignition
switch is in the LOCK/OFF position
and the vehicle shifted to P (Park).
After charging has started, you can
use electrical components such as
the radio by placing the ignition
switch in 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 ignition switch to the
LOCK/OFF position, and discon-
nect the charging cable. Then, con-
nect the charging cable.8. After charging has started, the esti-
mated charging time is displayed on
the instrument cluster for about 1
minute.
If you open the driver seat door
whilst charging, the estimated charg-
ing time is also displayed on the
instrument cluster for about 1
minute.
When scheduled charging is set, the
estimated charging time is displayed
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.
