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.

DANGER
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 fol-
low procedure in service manu-
al.

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
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.

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.
Refer to Chapter 6 for towing infor- mation or call Kia Roadside
Assistance.
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
After parking the vehicle, shiftthe transmission into "P"
position. Turn off the hybrid
system by pushing the Engine
Start/Stop button.

wires or cables, because an
electrical shock may occur
causing injury or death.
If a fire occurs, to extinguish a small high-
voltage battery fire, the follow-
ing techniques can be used: (Continued)
(Continued)- Dry chemical
- CO2
- Large amounts of water
- Regular foam
For a large high-voltage bat-
tery fire, use these types of
extinguishing methods:
- Large amounts of water
- Fog
- Regular foam
If you need towing, refer to chapter 6.

Introduction
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.
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.
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
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.
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.

No special break-in period is need-
ed. By following a few simple precau-
tions for the first 1,000 km (600
miles) you may add to the perform-
ance, economy and life of your vehi-
cle.
Do not race the engine.
While driving, keep your enginespeed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 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 emer- gencies, to allow the brakes to seat
properly.
Don't tow a trailer during the first 2,000 km (1,200 miles) of opera-
tion. By following a few simple precau-
