Ready Indicator
This indicator illuminates :
When the vehicle is ready to be driven.
- ON : Normal driving is possible.
- OFF : Nor
mal driving is not possible,
or a problem has occurred.
- Blinking : Emergency driving. When the ready indicator goes OFF
or blinks, there is a problem with the

Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low) or 0” level, the vehi-
cle automatically operates the
engine to charge the battery. However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the “L (Low) or 0”
level, we recommend the vehicle be
checked by an authorized Kia dealer.
✽✽
NOTICE
Never try to start the vehicle if the
fuel tank is empty. In this condition,
the engine cannot charge the high
voltage battery of the hybrid system.
If you try to start the vehicle when
the fuel is empty, the high voltage
battery will become discharged and
be damaged.

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 for the times when the engine acts as a generator, such as when stopped at idle.
Charging also occurs when decelerating or by regenerative braking.

PHEV (PLUG-IN ELECTRIC VEHICLE) SYSTEM
The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid electric vehicle and an
all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and the elec‐ tric 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 distance until
the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and road conditions. Ag‐ gressive 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.

You can monitor the charging status
outside of the vehicle when charging the high-voltage battery.

Scheduled charging (if equipped)
• You can set reserved charging using the AVN.
Refer to the AVN for detailed infor‐mation about setting reserved charg‐
ing.
• Scheduled charging can only be done when using a normal charger or the
portable charging cable (ICCB: In-Ca‐
ble Control Box).
0 + ' ) 1 2 -
• 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 immediatelywhen the normal charger or portable
charging cable (ICCB: In-Cable Control
Box) is connected. When immediate
charging is required, use the AVN to
deactivate the scheduled charge set‐ ting.

• Always keep the charging connectorand charging plug in clean and dry
condition. Be sure to keep the charg‐ ing cable in a condition where there is
no water or moisture.
• Make sure to use the designated charger for charging the vehicle. Us‐
ing any other charger may cause fail‐
ure.
• Before charging the battery, turn the vehicle OFF.
• Be careful not to drop the charging connector. The charging connector
can be damaged.Normal charge

4. Remove any dust on the chargingconnector and charging inlet.
5. Hold the charging connector handle. Then, insert it into the charging in‐
let, until you hear a click sound. If it
is not fully connected, a bad con‐
nection between the charging con‐
nector and the charging terminals
may cause a fire.

6. Check if the charging cable connec‐ tion indicator of the high voltage
battery in the instrument cluster is
turned ON.
Charging does not occur when the
indicator is OFF. When the charging
connector is not connected proper‐
ly, reconnect the charging cable to
charge.
NOTICE
•The charging is in progress only
with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. Howev‐
er, it may discharge the 12-V
battery. Thus, if possible, charge
the battery with the Engine
Start/Stop button in the OFF po‐
sition.
•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 En‐
gine Start/Stop button to the
OFF position, and disconnect the
charging cable. Then, connect
the charging cable.
