THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING - High Waters
• Avoid driving through high waters as this may result in
your vehicle becoming saturat-
ed with water and could com-
promise the high voltage com-
ponents.
Do not touch the any of the high voltage components within
your vehicle if your vehicle has
been submerged in water equal
to half of the vehicle height.
Touching high voltage compo-
nents once submerged in water
could result in severe burns or
electric shock that could result
in death or serious injury.
WARNING - Battery
Electrolyte
As with all batteries, avoid fluid
contact with the Hybrid battery.
If the battery is damaged and if
electrolyte comes in contact
with your body, clothes or eyes,
immediately flush with a large
quantity of fresh water.
WARNING - After-market
Battery Charger
Do not use an after-market bat-
tery charger to charge the Hybrid
battery without confirming that it
meets all safety and effective-
ness specifications for this prod-
uct. An inadequate hybrid battery
may malfunction and result in
death or serious injury.

CAUTION - Cleaning
Engine
When you clean the enginecompartment, do not washusing water. Water may causeelectric arcing to occur anddamage electronic parts andcomponents.
WARNING
-
Exposure to High Voltage
High voltage in the hybrid bat- tery system is very dangerous
and can cause severe burns
and electric shock. This may
result in serious injury or
death.
For your safety, never touch, replace, dismantle or remove
any portion of the hybrid bat-
tery system including compo-
nents, cables and connectors.
WARNING - Use of Water
or Liquids
If water or liquids come into
contact with the hybrid system
components, and you are also
in contact with the water, severe
injury or death due to electrocu-
tion may occur.
WARNING - Hot
Components
When the hybrid battery system
operates, the HEV battery sys-
tem can be hot. Heat burns may
result from touching even insu-
lated components of the HEV
system.

H13
Service plug
This service plug (1) located in the
rear trunk as shown should always
be pulled out to disconnect and turn
off the hybrid system.
IMPORTANT: Wait 5 minutes after
this lever is disconnected to work
on the car. This ensures that all
remaining electrical charge in the
system is dissipated.
Some Special Characteristics
of the Hybrid Vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid 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 compartment. If
you depress the brake pedal repeat-
edly when the hybrid system is
turned on, you may hear a sound in
the engine compartment. None of
these sounds indicate a problem.
They are normal characteristics of
hybrid vehicles.
When the hybrid system is turned
on, the engine may or may not start
immediately. This does not indicate a
malfunction. If the "READY" symbol
is on, the hybrid system is operating.
Even if the gasoline engine is off, you
can operate the vehicle.

WARNING - Safety plug
Never touch the safety plug.
Safety plug is attached to high
voltage hybrid battery system.
Touching safety plug can result
in death or serious injury.
Service personnel should follow
procedure in service manual.
WARNING - Interference
with electronic medical
devices
Electromagnetic waves that are
generated from the charger can
impact medical electric devices
such as an implantable cardiac
pacemaker.
When using such medical elec-
tric devices, ask your medical
professional and the device
manufacturer whether charging
your electric vehicle will impact
the operation of the medical
electric devices.

H14The HEV system may emit electro-
magnetic waves which can affect the
performance of electronic devices,
such as laptop computers.
If you park the vehicle for a long time,
the hybrid system will discharge. The
vehicle should be driven at least
once 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 vehi-
cle even if the engine is stopped.
Virtual Engine Sound
System(VESS)
The Virtual Engine Sound System
generates an engine sound for
pedestrians to hear the vehicle while
at low speeds in EV mode.
WARNING - Turning off
HEV system
When you leave the vehicle, turn
off the hybrid system. If you
leave the hybrid system on, you
or another vehicle occupant
could depress the accelerator
pedal and, if it is in a position
other than Park, the vehicle will
begin accelerating. This may
result in an accident causing
serious injury or death.

H16
If An Accident Occurs
Avoid the engine compartment.
Avoid any orange or high voltagewires, cables, or components.
Assume that a high voltage com- ponent is exposed and move away
from the vehicle as promptly as
possible.

Your new Kia vehicle is designed to
use only unleaded fuel having a
pump octane number ((R+M)/2) of
87 (Research Octane Number 91) or
higher. (Do not use methanol blend-
ed fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult an
authorized Kia dealer for details.)Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline.
Pursuant to EPA regulations, ethanol
may be used in your vehicle.
Do not use gasohol containing more
than 10% ethanol, and do not use
gasoline or gasohol containing any
methanol. Ethanol provides less
energy than gasoline and it attracts
water, and it is thus likely to reduce
your fuel efficiency and could lower
your MPG results.
Methanol may cause drivability prob-
lems 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 prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of: 1. Gasoline or gasohol containing
methanol.
2. Leaded fuel or leaded gasohol.
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. Kia recom-
mends that customers do not use
fuel with an ethanol content exceed-
ing 10 percent.
✽ ✽

NOTICE
Your New Vehicle Limited
Warranty does not cover damage to
the fuel system or any performance
problems caused by the use of “E85”
fuel.
FUEL REQUIREMENTS
WARNING - Refueling
• Do not "top off" after the nozzle automatically shuts off.
Attempts to force more fuel
into the tank can cause fuel
overflow onto you and the
ground causing a risk of fire.
Always check that the fuel cap is installed securely to prevent
fuel spillage in the event of an
accident.

Introduction
Other fuels
Using fuels such as
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) containedfuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained fuels,
may cause vehicle and engine dam-
age.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate or cause plug-
ging, misfiring, poor acceleration,
engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion, etc.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as MMT (Methylcyclopentadi-
enyl Manganese Tricarbonyl).
Kia does not recommend the use of
gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle
performance and damage components
of the fuel system, engine control sys-
tem and emission control system.
✽ ✽

NOTICE
Your New Vehicle Limited
Warranty may not cover damage to
the fuel system and any perform-
ance problems that are caused by
the use of fuels containing methanol.
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which helps
prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance of the Emission Control
System. For more information on
TOP TIER Detergent Gasoline,
please go to the website (www
.top-
tiergas.com).
For Customers who do not use TOP
TIER Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at 7,500 miles or every
engine oil change is recommended.
Additives are available from your
authorized Kia dealer along with
information on how to use them. Do
not mix other additives.
