• 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

Then, insert it into the charging in‐
let, until you hear a click sound. If it
is not fully connected, improper
connection between the charging
connector and the charging termi‐
nals are a potential fire hazard.

9. 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.

STARTING THE HYBRID/PLUG-IN HYBRID VEHICLE (SMART KEY)
Starting the hybrid system
1. Carry the smart key into the vehi‐cle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in the P (Park) position.
In N (neutral) position, you cannot
start the vehicle.
4. Depress the brake pedal.
5. Press the engine start/stop button.
6. The engine should be started with‐ out pressing the accelerator. In ex‐
tremely cold weather or after the
vehicle has not been operated for several days, let the engine warm
up without depressing the acceler‐
ator. • Even if the smart key is in the ve‐ hicle, if it is far away from you, the engine may not start. • When the engine start/stop but‐
ton is in the ACC or ON position, if
any door is open, the system
checks for the smart key. If the
smart key is not in the vehicle,
the warning, "Key is not in vehi‐
cle" will come on, and if all doors
are closed, the chime will also
sound for about 5 seconds. The
indicator will turn off while the
vehicle is moving. Keep the smart
key in the vehicle when using the
ACC position or if the vehicle en‐
gine is on.
If the starting procedure is followed,the "READY" symbol on the instrumentcluster will turn on. For more details,please refer to L

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
nHot Components
When the hybrid battery system op‐erates, the HEV battery system canbe hot. Heat burns may result fromtouching even insulated componentsof the HEV system.
Safety plug
DANGER
Never touch the safety plug. Safetyplug is attached to high voltage hy‐brid battery system. Touching safe‐ty plug will result in death or seriousinjury. Service personnel should fol‐low procedure in service manual.
Some special features of the
hybrid vehicle
Hybrid vehicles sound different than
gasoline engine vehicles. When the hy‐ brid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the accelerator pedal rapidly, you may hear
a sound. When you apply the brake
pedal, you may hear a sound from the regenerative brake system. When the
hybrid system is turned off or on, you
may hear a sound in the engine com‐ partment. If you depress the brake
pedal repeatedly when the hybrid sys‐
tem is turned on, you may hear a sound in the engine compartment.
None of these sounds indicate a prob‐
lem.
They are characteristics of hybrid vehi‐ cles. When the hybrid system is turned on,
the engine may run. This does not indi‐
cate a malfunction. If the "READY" symbol is on, the hybrid system is op‐
erating. Even if the gasoline engine is
off, you can operate the vehicle.
The HEV system may emit electromag‐ netic waves which can affect the per‐
formance of electronic devices applian‐
ces, such as laptop computers, which are not part of the vehicle design.
If you park the vehicle for a long time,
the hybrid system will discharge. You
need to drive the vehicle several times per month to maintain a charge.
When you start the hybrid system in
the "P" transmission position, the
"READY" symbol is illuminated in the cluster. The driver can drive the vehicle
even if the engine is stopped.
WARNING
When you leave the vehicle, youshould turn off the hybrid system. Ifyou depress the accelerator pedal bymistake and the vehicle is not in the"P" position, the vehicle will acceler‐ate. This may result in serious injuryor death.

3.Leave the vehicle and evacuateto the safety place.
4.Call emergency services for helpand let them know the vehicle isa Hybrid vehicle.
If you have an extinguisher, extin‐guish a fire carefully.Do not touch high voltage cables,connectors and package modules.High voltage components are orangein color.Exposed cables or wires may be visi‐ble inside or outside of the vehicle.Never touch the wires or cables, be‐cause an electrical shock may occurcausing injury or death.
WARNING
If a submersion in water occurs:If your vehicle was flooded and hassoaked carpeting or water on theflooring, you should not try to startthe Hybrid system. Never touch thehigh voltage cables, connectors andpackage modules, because an elec‐

trical shock may occur causing injuryor death. High Voltage cables are or‐ange in color.We recommend that the car towedto an authorized Kia dealer.
When the hybrid vehicle shuts
off
When the high voltage battery or 12-
volt battery discharges, or fuel tank is empty, the hybrid system may not op‐
erate.
If the Hybrid system stops operating
while the vehicle is moving, reduce the vehicle speed gradually. Pull your vehi‐
cle off the road in a safe area, and shift
the transmission in to Park (P) position and: 1. Turn on the hazard warning flash‐ ers.
2. Set the start button at OFF, and try to start the Hybrid system by ap‐
plying the brake pedal and pushing
the start button.
3. If the Hybrid system will not oper‐ ate, refer to L

VEHICLE BREAK-IN PROCESS
No special break-in period is needed. By
following a few simple precautions for
the first 1,000 km (600 miles) you may add to the performance, economy and
life of your vehicle. • Do not race the engine.
• While driving, keep your engine speed (rpm, or revolutions per minute)
within 3,000 rpm.
• Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is needed
to properly break-in the engine.
• Avoid hard stops, except in emergen‐ cies, to allow the brakes to seat
properly.
