H2
HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The Kia Hybrid Electric Vehicle (HEV) uses both the gasoline 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
battery.
The HEV battery charge must be maintained because, at times, the engine may come on even at idle to act as a gen-
erator. Charging also occurs when decelerating or by regenerative braking.

H3
PHEV (PLUG-IN ELECTRIC VEHICLE) SYSTEM
The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid electric vehi-
cle 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 Charger: The plug-in hybridvehicle 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 Charger: The plug-in hybrid vehicle can be charged by using
household electricity. 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
AC Charger: Takes about from 2
and a half hours to 3 hours at room
temperature (Can be charged to
100%.). Depending on the condition and
durability of the high-voltage bat-
tery, charger specifications, and
ambient temperature, the time
required for charging the high-volt-
age battery may vary.
Trickle Charger: For charging at home. Please note that the Trickle
Charger is slower than the AC
Charger.

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 reserved chargingusing the AVN.
Refer to the AVN for detailed infor-
mation about setting reserved
charging.
Scheduled charging can only be done when using a AC charger or
the portable charging cable (ICCB:
In-Cable Control Box).

H8 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 moisture.
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.

WARNING - Charging
cable
• Immediately stop charging when you discover 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.
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 - 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.

H104. Remove any dust on the charging
connector and charging inlet.
5. Hold the charging connector han- dle and insert it into the charging
inlet while pressing the release
button, until you hear a click
sound. If it is not fully connected, a
bad connection between the
charging connector and the charg-
ing terminals may cause a fire. 6. Check if the charging cable con-
nection indicator of the high volt-
age battery in the instrument clus-
ter is turned ON.
Charging does not occur when the
indicator is OFF. When the charg-
ing connector is not connected
properly, reconnect the charging
cable to charge.
✽ ✽ NOTICE
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),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.

played on the instrument cluster
for about 1 minute. It is also dis-
played when the driver's door is
opened with charging in progress.
When scheduled charging is set,
the estimated charging time is dis-
played as “--” .

CAUTION
In order to disconnect thecharging connector, unlock thedoors to unlatch the chargingconnector lock system. If not,the charging connector and thevehicle's charging inlet may bedamaged.
CAUTION
When disconnecting the charg-ing connector, do not try to dis-connect it by force while notpressing the release button.This may damage the chargingconnector and vehicle charginginlet.

H14When you cannot drive to a public
charging station due to low battery,
you can charge the car by using the
220V portable charger (ICCB: In
Cable Control Box) which you can
buy as an option.
✽ ✽
NOTICE
This cable is designed to prevent
problems caused by unexpected bat-
tery discharge and when you use
general outlets, it may lead to exces-
sive electricity charges as the elec-
tricity charges for electric vehicles
will not be applied. So refrain from
using it to fully charge your car.
How to Set Charging Current of
Portable Charging Cable
1. Check the outlet’s current rating before connecting the plug to the
outlet.
2. Connect the power plug to the household electrical outlet.
3. Check the status of the control box display. 4. Adjust the charging current by
pressing the button (1) on the
back of the control box for more
than 1 second. (Refer to the exam-
ples of charging cable type and
charging current setting.)
5. Each time the button (1) is pressed, the control box display is
sequentially changed to 12A, 10A
and 8A.
6. Once the charging current setting is complete, start charging accord-
ing to Trickle Charge procedure.
