Changing plug-in hybrid mode
Pressing the HEV button changes he
plug-in hybrid system modes, as
described:
Briefly 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.
- Briefly pressed: It changes to the
CS mode.
- Press and hold: It remains in the HEV-charging mode.

Unplug vehicle to start (Plug-in hybrid)
This 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)
This 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 time (Plug-in hybrid)
This message is displayed to notify
the remaining time to fully charge the
battery.
Battery charged. Maintaining cur-rent mode (Plug-in hybrid)
This message is displayed when the
vehicle is unable to convert to charg-
ing 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 Hybridmode (Plug-in hybrid)
This message is displayed when the
vehicle is unable to convert to EV
mode even when pressing the HEV
button during HEV mode driving due
to insufficient high-voltage (hybrid)
battery level.
Low battery temp. Maintainingcurrent (Plug-in hybrid)
This message is displayed when the
vehicle is unable to convert to EV
mode even when pressing the HEV
button during HEV mode driving due
to low battery temperature.

Charging complete. Switching toHybrid (Plug-in hybrid)
This message is displayed when the
vehicle automatically converts to
HEV mode due to completed battery
charging during charging mode driv-
ing.
Charger Error! (Plug-in hybrid)
This message is displayed when the
charging failed due to an external
charger error.
This message is for and applies to
the Normal charger. The purpose of
this message informs you there is an
issue with the charger. Recommend
to use another charger.
Low/High System Temp.Maintaining Hybrid (Plug-in hybrid)
This message is displayed when the
vehicle is unable to convert to EV
mode even when pressing the HEV
button during 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, this message will be dis-
played 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 driver
of energy flow in various operating
modes. Eleven Modes show the driv-
er the current operating condition.Vehicle Stop
The mode means the vehicle is at a
complete stop.
(There is no energy flow.)

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 " " symbol will illuminate in
the cluster when the system is oper-
ational.
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
to operate the electric motor and
other components. High voltage is
dangerous if touched.
Your vehicle is equipped with orange
colored insulation which covers over
the high voltage components to pro-
tect people from electric shock.
High voltage warning labels are
attached to some system compo-
nents as additional warnings. Your
vehicle is recommended to be serv-
iced by an authorized Kia dealer.
WARNING - High voltage
components
Never touch orange or high-volt-
age labeled components includ-
ing wires, cables, and connec-
tors. If the insulators or covers
are damaged or removed, severe
injury or death from electrocu-
tion may occur.
WARNING- Touching HPCU
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.
