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 components as addi-
tional warnings. Have your vehicle
serviced by an authorized Kia dealer.
WARNING - High voltage
components
Never touch orange-colored or
high voltage labeled compo-
nents including wires, cables,
and connectors. If the insula-
tors or covers are damaged or
removed, severe injury or death
from electrocution may occur.
WARNING - Avoid
Touching Hybrid Power
Control Unit
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.

✽ ✽
NOTICE - Prolonged parking
Prolonged parking might cause bat-
tery discharge and operation failure
due to natural discharge. Driving
the vehicle approximately once
every 2 months, more than 9 miles
(15 km) is recommended. The bat-
tery will be charged automatically
when driving the vehicle.
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 system
can be hot. Heat burns may result
from touching even insulated
components of the HEV system.
CAUTION - Cleaning

When you clean the engine com-
partment, do not wash using
water. Water may cause electric
arcing to occur and damage elec-
tronic parts and components.

H46
Safety plugSome Special Features 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 characteristics of hybrid
vehicles.
When the hybrid system is turned on,
the engine may run. This does not
indicate a malfunction. If the " "
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.
The safety plug is attached to
the high voltage hybrid battery
system. Touching the safety
plug may result in death.
Service personnel should fol-
low the appropriate procedures
in the service manual.

H47
The HEV system may emit electro-
magnetic waves which can affect the
performance of electronic devices
appliances, such as laptop comput-
ers, 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 approximate-
ly once every 2 months, more than 9
miles (15 km) is recommended.
When you start the hybrid system in
the "P" transmission position, the
" " 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 engine sound for pedestri-
ans to hear vehicle sound because
there is limited sound while electric
motor power is used.
If the vehicle is moving at low
speed, the VESS will operate.
When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
WARNING - Turning off
HEV system
When you leave the vehicle, you
should turn off the hybrid sys-
tem. If you depress the acceler-
ator pedal by mistake and the
vehicle is not in the "P" posi-
tion, the vehicle will accelerate.
This may result in serious injury
or death.

H48
High Voltage Battery Air Intake
The hybrid battery air intake is locat-
ed on bottom and side of the rear
seats. The air intake cools down the
hybrid battery. When the hybrid bat-
tery air intake is blocked, the hybrid
battery may be overheated. Do not
obstruct the air intake with any other
objects.
If An Accident Occurs
Avoid the engine compartment.
Avoid making contact with any
orange or high voltage wires,
cables, or components.
Assume that a high voltage compo-
nent is exposed and move away from
the vehicle as promptly as possible.
Refer to Chapter 7 for towing infor-
mation.WARNING - Air Intake
Blocking the air intake behind
the rear seats may damage
the HEV battery.
Do not allow any water into
the air intake even when
cleaning. If any water enters
the air intake, the Hybrid bat-
tery may cause an electric
shock which can cause seri-
ous injury or death due to
electrocution.

WARNING
-
Interference with electron-
ic 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 electric devices, ask
your medical professional and
the device manufacturer
whether charging your electric
vehicle will impact the operation
of the medical electric devices.

High voltage components are
orange in color.
Exposed cables or wires may be vis-
ible inside or outside of the vehicle.
Never touch the wires or cables,
because an electrical shock may
occur causing injury or death.
WARNING
If a small scale fire occurs,
use a fire extinguisher (ABC,
BC) that is meant for electrical
fires.
If it is impossible to extin-
guish the fire in the early
stage, remain a safe distance
from the vehicle and immedi-
ately call your local fire emer-
gency responders. Also,
advise them that a hybrid
vehicle is involved.
If the fire spreads to the high
voltage battery, large amount
of water is needed to put out
the fire.
Using small amount of water
or fire extinguishers not
meant for electrical fires
could cause serious injury or
death from electrical shocks.
If you need towing, refer to
chapter 6.

Introduction
2 1
Your new 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.)
• Tighten the cap until it clicks one
time, otherwise the Check Engine
light will illuminate.
Gasoline containing alcohol and
methanol
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 15% 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.
3. Gasohol containing more than
15% ethanol.
WARNING - Refueling
• Do not “top off” after the noz-
zle 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 pre-
vent fuel spillage, especially
in the event of an accident.
