Changing plug-in hybrid mode
Pressing the HEV button changes
the plug-in hybrid system modes, as
below.
Shortly pressed:EV mode ↔ HEV mode
Press and hold: It changes to the HEV-charging
mode. When the HEV button is pressed in
the HEV-charging mode, the mode
changes as below.
- Shortly pressed : It changes to the
CS mode.
- Press and hold: It remains in the HEV-charging mode.

Unplug vehicle to start (Plug-in hybrid)
The message is displayed when you
start the engine without unplugging
the charging cable. Unplug the
charging cable, and then start the
vehicle.
Shift to P to charge(Plug-in hybrid)
The message is displayed when the
charging connector is plugged with
the shift lever in R (Reverse), N
(Neutral) or D (Drive). Move the shift
lever to P (Park) and re-start the
charging process.
Remaining charge time(Plug-in hybrid)
The message is displayed to notify
the remaining time to fully charge the
battery.
EV / HEV/ CHG modes (Plug-in hybrid)
A corresponding message is dis-
played when a mode is selected by
pressing the HEV button.
Battery charged. Maintaining cur-rent (Plug-in hybrid)
This message is displayed when
unable to convert to charging mode
even when pressing and holding the
HEV button during EV/HEV mode
driving because the high-
voltage(hybrid) battery is already
fully charged.
Low battery. Maintaining Hybrid(Plug-in hybrid)
This message is displayed when
unable to convert to EV mode even
when pressing the HEV button dur-
ing HEV mode driving due to insuffi-
cient high-voltage(hybrid) battery
level.

H25
Low battery temp. Maintainingcurrent (Plug-in hybrid)
This message is displayed when
unable to convert to EV mode even
when pressing the HEV button dur-
ing HEV mode driving due to low bat-
tery temperature.
Charging complete. Switching toHybrid (Plug-in hybrid)
This message is displayed automati-
cally converting to HEV mode due to
completed battery charging during
charging mode driving.
Charger Error! (Plug-in hybrid)
This messages is displayed when
the charging failed by external charg-
er error.
This message is for Normal charger.
The purpose of this message is to let
you know the error has occurred in
charger itself not in vehicle.
Low/High System Temp.Maintaining Hybrid (Plug-in hybrid)
This message is displayed when
unable to convert to EV mode even
when pressing the HEV button dur-
ing HEV mode driving due to
low/high system temperature
Switching to Hybrid mode toallow heating (Plug-in hybrid)
When the coolant temperature is lower than 57 °F (-14 °C), and you
turn the climate control On for
heating, the above message will be
displayed in the cluster. Then, the
vehicle will automatically switch to
HEV mode.
When the coolant temperature is higher than 57 °F (-14 °C), or you
turn the climate control Off, the
vehicle will automatically return to
EV mode.

Kia hybrid system notifies the drivers
of energy flow in various operating
modes. Eleven Modes show drivers
the current operating condition.Vehicle Stop
The mode means the vehicle at stop.
(There is no energy flow.)

H33
ECONOMICAL and SAFE
OPERATION of Hybrid system
Drive smoothly. Accelerate at amoderate rate and maintain a
steady cruising speed. Don't make
"jack-rabbit" starts. Don't race
between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine runs in "N" posi- tion, the hybrid system cannot gen-
erate electricity. The hybrid battery
cannot recharge in "N" position.
Please refer to chapter 6.
✽ ✽ NOTICE
When the hybrid system is in
READY mode, the engine will auto-
matically start and stop as needed.
The "READY" symbol will illumi-
nate in the cluster when the system
is operational.
CAUTION- Extended
cranking
Do not crank the engine for aprolonged period of time with-out the engine starting. Thiscould result in damage to theHEV battery and become totallydischarged.

H35
The Hybrid battery uses high voltage
top operate the electric motor and
other components and other compo-
nents. High voltage is dangerous if
touched.
Your vehicle is equipped with orange
colored insulation and covers over
the high voltage components to pro-
tect people from electric shock. High
voltage warning labels are attached
to some system components as
additional warnings. Your vehicle is
recommended to be serviced by an
authorized Kia dealer.
WARNING
Never touch orange or high volt-
age labeled components includ-
ing wires, cables, and connec-
tions. If the insulators or covers
are damaged or removed, severe
injury or death from electrocu-
tion may occur.
WARNING- TouchingHPCU
When replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU could result in electrocu-
tion, serious injury, or death.
