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‐

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.

Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System gen‐
erates an engine sound for pedestrians to hear vehicle while at low speeds in
EV mode.
High voltage battery air intake
Hybrid battery air intake
The hybrid battery air intake is located
on the bottom of the rear seats. The air intake cools down the hybrid bat‐
tery. When the hybrid battery air in‐
take is blocked, the hybrid battery may be overheated. Do not obstruct the air
intake with any other objects.

The high-voltage battery air intake is
located on the left side of the rear seats. The air intake cools down the
high-voltage battery.
When the high-voltage battery air in‐
take is blocked, the high-voltage bat‐ tery may be overheated and the vehicle
performance may become limited and
set a hybrid warning lamp. Do not ob‐ struct the air intake with any other ob‐
jects.
WARNING
nAir Intake
•Blocking the air intake behind therear seats may damage the HEVbattery.
•Do not allow any water into the airintake even when cleaning. If anywater enters the air intake, theHybrid battery may cause an elec‐tric shock which can cause seriousinjury or death due to electrocu‐tion.
If an accident occurs
• Avoid the engine compartment.
• Avoid any orange or high voltage wires, cables, or components.
• Assume that a high voltage compo‐ nent is exposed and move away fromthe vehicle as promptly as possible.
• Refer to L

WARNING
•After parking the vehicle, shift thetransmission into "P" position. Turnoff the hybrid system by pushingthe Engine Start/Stop button.
•For your safety, do not touch highvoltage cables, connectors andpackage modules. High Voltagecomponents are orange in color.
•Exposed cables or wires may bevisible inside or outside of the ve‐hicle. Never touch the wires or ca‐bles, because an electrical shockmay occur causing injury or death.

FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded gasoline with an octane rating of RON
(Research Octane Number) 95 / AKI
(Antiknock Index) 91 or higher.
You may use unleaded gasoline with an octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle. (Do not use methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num‐ ber) 91 / AKI (Antiknock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain maximum performance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The useof leaded fuel is detrimental to thecatalytic converter and will damagethe engine control system’s oxygensensor and affect emission control.Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (We recom‐mend that you consult an authorizedKia dealer for details.)
WARNING
•Do not "top off" after the nozzleautomatically shuts off when re‐fueling.
•Always check that the fuel cap isinstalled securely to prevent fuelspillage in the event of an acci‐dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
signed to use leaded gasoline. When you are going to use leaded gasoline,
we recommend that you ask an au‐
thorized Kia dealer whether leaded gasoline in your vehicle is available or
not.
Octane Rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol), and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or in‐ stead of leaded or unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use gas‐
oline or gasohol containing any metha‐ nol. Either of these fuels may cause
drivability problems and damage to the
fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufac‐ turer’s warranty if they result from the
