Introduction
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 onetime, 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 percent ethanol
FUEL REQUIREMENTS
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.

Introduction

"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 15 percent.
✽ ✽
NOTICE
Your New Vehicle Limited Warranty
does not cover damage to the fuel sys-
tem or any performance problems
caused by the use of “E85” fuel.
✽ ✽
NOTICE
Never use any fuel containing
methanol. Discontinue use of any
methanol containing product which
may inhibit proper drivability.
Other fuels
Using fuels that contain Silicone (Si),
MMT (Manganese, Mn), Ferrocene
(Fe), and Other metalic additives,
may cause vehicle and engine dam-
age or cause misfiring, poor acceler-
ation, engine stalling, catalyst melt-
ing, clogging, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽
NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warranty.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives Such as
MMT(Methylcyclopentadienyl
Manganese Tricarbonyl). Kia does not
recommend the use of gasoline con-
taining MMT. This type of fuel can
reduce vehicle performance and affect
your emission 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.

Introduction
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 performance
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 you can buy separately 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 recommended.
Additives are available from your
authorized Kia dealer along with infor-
mation 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 regardingregistration and insurance.
Determine that acceptable fuel is available.

This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronicdevices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices. No special break-in period is need-
ed. By following a few simple precau-
tions for the first 600 miles (1,000
km) you may add to the perform-
ance, economy and life of your vehi-
cle.
Do not race the engine.
While driving, keep your engine
speed (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 1,200 miles (2,000 km) of operation.
Fuel economy and engine perform- ance may vary depending on vehi-
cle break-in process and stabilize
after driving about 3,750 miles
(6,000 km) Engines may consume
more oil during the vehicle break-in
period.

Driver’s seat belt warning
As a reminder to the driver, the
Driver’s seat belt warning lights will
illuminate for approximately 6 sec-
onds each time you turn the ignition
switch or ENGINE START/STOP but-
ton ON regardless of belt fastening.
If the seatbelt is not fastened, the
warning chime will sound for about 6
seconds. If you start to drive without
the seat belt fastened or you unfas-
ten the seat belt when you drive
under 12 mph (20 km/h) or stop, the
corresponding warning light will illu-
minate. If you start to drive without the seat
belt fastened or you unfasten the
seat belt when you drive 12 mph (20
km/h) and faster, the warning light
will blink and warning chime will
sound for approximately 100 sec-
onds.
When the seat belt is unfastened
during driving, the warning light will
illuminate when the speed is under
12 mph (20 km/h).
When the speed is 12 mph (20 km/h)
and faster, the warning light will blink
and warning chime will sound for
approximately 100 seconds.
WARNING- Twisted seat
belt
Make sure your seat belt is not
twisted when worn. A twisted
seat belt may not properly pro-
tect you in an accident and
could even cut into your body.
WARNING- Seat belt buckle
Do not allow foreign material
(gum, crumbs, coins, etc.) to
obstruct the seat belt buckle.
This may prevent the seat belt
from fastening securely.1GQA2083
