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 240V 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.
The engine can be turned on based on a number of factors such as heater usage and a frequent operation of the
accelerator pedal by a driver in Charge Depleting mode.

Charging Information
• AC Charger: 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 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. Use only as a back-
up charger.
Charging Time
AC Charger: Takes about 2 hours
15 minutes 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.

If you press the scheduled charging
deactivation ( ) button to immedi-
ately charge the battery, charging
must be initiated 3 minutes 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
Infotainment System to finalize the
deactivation.Refer to "AC Charge or Trickle
Charge" for details about connect-
ing the AC Charger and the
portable charger (ICCB: In-Cable
Control Box).
Charging Precautions

■AC Charger
WARNING
-
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.

H11
Always keep the charging connec-
tor and charging plug clean and
dry. Be sure to keep the charging
cable in a condition where there is
no water or moisture.
Before charging the battery, turn
the vehicle OFF.
Be careful not to drop the charging
connector. The charging connector
can be damaged.
Always inspect the charging con-
nector terminals for damage or
overheating. Do not use if dam-
aged, as this may damage the
vehicle side charge connector and
is not a warrantable repair.AC Charge
You can charge your vehicle by plug-
ging into a public charger at a charg-
ing station.
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 engine compartment
or interior rear seat may auto-
matically operate.

WARNING
Make sure to use the designat-
ed charger for charging the
vehicle.Using any other charger
may cause failure or lead to
electric shock or fire.
(Continued)
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.

H13
7. 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
• Charging is in progress only when
the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the bat-
tery with the Engine Start/Stop
button in the OFF position.
• The charging process is interrupt-
ed temporarily when the shift lever
is moved from P (Park) to Not P(R
(Reverse)/N (Neutral)/D (Drive))
during charging. To resume(restart)
charging, move the shift lever to the
P (park) position. Then, the charging
process is resumed(restarted).
8. After charging has started, the
estimated charging time is dis-
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 “--” .

H14
Unlock Connector in Emergency
If the charging connector does not
unlock for some reason, open the
hood and slightly pull the emergency
cable as shown above. The charging
door will then open.
If the charging door does not opened
immediately after pulling the emer-
gency cable in, press the charging
door lightly and pull the emergency
cable again.
The charging cable lock may not
work properly when foreign materials
such as dust enter the cable or the
cable is encrusted with ice.In that case, the charging cable may
not be disconnected or locked, or the
vehicle may not be charged. If this
happens, open the hood and pull the
emergency cable lightly 2 to 3 times
and then try to disconnect the charg-
ing cable or start recharging.

Checking Charging Status
You can check the charging status

How to Disconnect an AC charger
1.The vehicle must be in the AUTO
mode or the doors must be
unlocked in order to be able to dis-
connect the charging connector. A
lock system prevents charger
cable disconnection when the vehi-
cle's doors are locked.
2.While holding the charging con-
nector, pressing the locking
release button (1) and then pull it
out.
To prevent charging cable theft, the
charging connector cannot be dis-
connected from the inlet when the
doors are locked. Unlock all doors
to disconnect the charging connec-
tor from the inlet.
However, if the vehicle is in the
charging connector AUTO mode,
the charging connector automati-
cally unlocks from the inlet when
charging is completed.
ODEPQ017031
CAUTION
In order to disconnect the
charging connector, unlock the
doors to unlatch the charging
connector lock system. If not,
the charging connector and the
vehicle's charging inlet may be
damaged.
