Some 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.

The HEV system may emit electromag-
netic waves which can affect the per-
formance of electronic devices appli-
ances, 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
"

" symbol is illuminated in the

cluster. The driver can drive the vehi-
cle even if the engine is stopped.

WARNING

- Safety Plug

Never touch the safety plug.
Safety plug is attached to high
voltage hybrid battery system.
Touching safety plug will result
in death or serious injury.
Service personnel should follow
procedure in service manual.

WARNING

- Turning off

HEV system

When you leave the vehicle, you
should turn off the hybrid sys-
tem. If you depress the accelera-
tor pedal by mistake and the vehi-
cle is not in the "P" position, the
vehicle will accelerate. This may
result in serious injury or death.

H39

Virtual Engine Sound System
(VESS)

The Virtual Engine Sound System
generates 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 locat-
ed on bottom the rear seats. The air
intake cools down the hybrid battery.
When the hybrid battery air intake is
blocked, the hybrid battery may be
overheated. Do not obstruct the air
intake with any other objects.

Plug-in Hybrid Vehicle

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
intake is blocked, the high-voltage
battery may be overheated and the
vehicle performance may become
limited and set a hybrid warning
lamp. Do not obstruct the air intake
with any other objects.

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.

Fuel Additives

Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance perform-
ance of the Emission Control System.
For more information on TOP TIER
Detergent Gasoline, please go to the
website (www.toptiergas.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 can be purchased sepa-
rately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
should be added to the fuel tank at
every 7,500 miles (12,000 km) or
every engine oil change is recom-
mended. Additives are available from
your authorized Kia dealer along with
information on how to use them. Do
not mix other additives.

Operation in foreign countries

If you are going to drive your vehicle
in another country, be sure to:
• Observe all regulations regarding

registration and insurance.

• Determine that acceptable fuel is

available.

This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will assist
in understanding how a vehicle's
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
• How various systems in your

vehicle were operating;

• Whether or not the driver and

passenger safety belts were
buckled/ fastened;

• How far (if at all) the driver was

depressing the accelerator
and/or brake pedal; and,

• How fast the vehicle was travel-

ing.

These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle only
if a non-trivial crash situation
occurs; no data are recorded by
the EDR under normal driving
conditions and no personal data
(e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as
law enforcement, could combine
the EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investiga-
tion.

To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such
as law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.
