Warning and indicator lights
Ready indicator
This indicator illuminates:
When the vehicle is ready to be driven.
- ON: Normal driving is possi‐ ble.
- OFF: Normal 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 sys‐
tem. In this case, we recommend that
you have your vehicle inspected by an authorized Kia dealer.

Remaining charge time (Plug-in
hybrid)
The message is displayed to notify the
remaining time to fully charge the bat‐ tery.
EV/HEV/CHG modes (Plug-in
hybrid)
A corresponding message is displayed
when a mode is selected by pressing the HEV button.
Battery charged. Maintaining
current (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 al‐ ready 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 during HEV
mode driving due to insufficient high-
voltage (hybrid) battery level.
Low battery temp. Maintaining
current (Plug-in hybrid)
This message is displayed when unable
to convert to EV mode even when pressing the HEV button during HEV
mode driving due to low battery tem‐
perature.
Charging complete. Switching to
hybrid (Plug-in hybrid)
This message is displayed automatical‐
ly converting to HEV mode due to com‐
pleted battery charging during charging mode driving.
Charger error! (Plug-in hybrid)
This messages is displayed when the
charging failed by external charger er‐
ror.
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 during HEV mode driving due to low/high system
temperature.
Switching to hybrid mode to allow
heating (Plug-in hybrid)
• When the coolant temperature is lower than -14 °C (57 °F), and you
turn the climate control On for heat‐
ing, the above message will be dis‐
played in the cluster. Then, the vehi‐ cle will automatically switch to HEV
mode.
• When the coolant temperature is higher than -14 °C (57 °F), or you
turn the climate control Off, the vehi‐
cle will automatically return to EV mode.
Wait until fuel door opens (Plug-in
hybrid)
The message is displayed when you at‐
tempt to open the fuel filler lid with the fuel tank pressurized. Wait until the
fuel tank is depressurized.
NOTICE
•It may take up to 20 seconds to
open fuel filler lid.

COMPONENTS OF THE HYBRID/PLUG-IN HYBRID VEHICLE
0+')12-
1. Engine: 2.0L
2. Motor: 35 kW
3. Transmission: 6AT
4. Hybrid starter generator (HSG)
5. HPCU (Hybrid Power Control Unit)
6. High-voltage battery system
7. Regenerative brake system
8. Virtual Engine Sound System(VESS)
❈ The actual shape may differ from
the illustration.
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 and covers over the high voltage components to protect
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 voltagelabeled components including wires,cables, and connections. If the insu‐lators or covers are damaged or re‐moved, severe injury or death fromelectrocution may occur.
WARNING
When replacing the fuses in the en‐gine compartment, never touch theHPCU. The HPCU carries high volt‐age. Touching the HPCU could resultin electrocution, serious injury, ordeath.
CAUTION
•Do not pile up any items in an areabehind the high voltage battery. Ina crash, the battery may becomeunstable, or its performance maydegrade.
(Continued)
(Continued)
•Do not apply strong force nor pileup any items above the trunk.Such an attempt may distort thehigh voltage battery case, causinga safety problem or degrading theperformance.
•Be careful when loading inflamma‐ble liquid in trunk. It could causeoperational and safety degrada‐tion if the liquid leaks and flows inhigh voltage battery.

WARNING
As with all batteries, avoid fluid con‐tact with the Hybrid battery. If thebattery is damaged and if electro‐lyte comes in contact with yourbody, clothes or eyes, immediatelyflush with a large quantity of freshwater.
WARNING
Do not use an after-market batterycharger to charge the Hybrid bat‐tery. Doing so may result in death orserious injury.
WARNING
nHigh Waters
•Avoid high waters as this may re‐sult in your vehicle becoming satu‐rated with water and could com‐promise the high voltage compo‐nents.
(Continued)
(Continued)
•Do not touch any of the high volt‐age components within your vehi‐cle if your vehicle has been sub‐merged in water equal to half ofthe vehicle height. Touching highvoltage components once sub‐merged in water could result in se‐vere burns or electric shock thatcould result in death or serious in‐jury.
WARNING
nCarrying Liquids in Trunk
Do not load large amounts of waterin open containers into the vehicle. Ifthe water spills onto the HEV bat‐tery, it may cause a short and dam‐age the battery.
CAUTION
nCleaning Engine
When you clean the engine compart‐ment, do not wash using water. Wa‐ter may cause electric arcing to oc‐

cur and damage electronic parts andcomponents.
WARNING
nExposure to High Voltage
•High voltage in the hybrid batterysystem is very dangerous and cancause severe burns and electricshock. This may result in seriousinjury or death.
•For your safety, never touch, re‐place, dismantle or remove anyportion of the hybrid battery sys‐tem including components, cablesand connectors.
WARNING
nUse of Water or Liquids
If water or liquids come into contactwith the hybrid system components,and you are also in contact with thewater, severe injury or death due toelectrocution may occur.
