Introduction
A020101AHM-EU
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.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
A020103AUN-EU
Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels 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 problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning agents to the fuel tank other thanwhat has been specified. (Consultan authorized KIA dealer fordetails.)
WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks, oth- erwise the Malfunction Indicator
Light “ ” will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

Introduction

"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
KIA recommends that customers do not
use fuel with an ethanol content exceed-
ing 10 percent.A020104AUN
Use of MTBE
KIA recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
A020105AUN
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
A020106AUN
Gasolines for cleaner air
To help contribute to cleaner air, KIA rec-
ommends that you use gasolines treated
with detergent additives, 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.
A020107AUN
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-istration and insurance.
Determine that acceptable fuel is avail- able.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob-lems that are caused by the use of fuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs dri-vability.
CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuelsystem or any performance prob-lems caused by the use of “E85” fuel.

WARNING - Refueling
If pressurized fuel sprays out, itcan cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks, oth- erwise the Malfunction Indicator
Light will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.OMG035066OMG035067

Features of your vehicle
(Continued)Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)(Continued)
Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
When using an approved portable fuel container, be sure to
place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling has
begun, contact with the vehicle
should be maintained until the
filling is complete.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warningsposted at the gas station facility.
Before refueling, note the loca- tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.
