formance, safety or durability of your Hyundai and may, in addition, violate conditions of the limited
warranties covering the vehicle. Certain modifications may also be in violation of regulations estab-
lished by the U.S. Department of Transportation and other federal or state agencies.Your vehicle is equipped with electronic fuel injection and other electronic c\
omponents. It is possible
for an improperly installed/adjusted two-way radio or cellular telephone to adversely affect electronic
systems. For this reason, we recommend that you carefully follow the radio manufacturer's instruc-
tions or consult your Hyundai dealer for precautionary measures or special instructions if you choose

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.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Gasoline containing alcohol andmethanolGasohol, 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 than what has been specified. (Consultan authorized HYUNDAI dealer fordetails.)
WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.
 Tighten the cap until it clicks one time, otherwise the Malfunction
Indicator Light “ ” will illumi-
nate.
 Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

Introduction41"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.
HYUNDAI recommends that customers
do not use fuel with an ethanol content
exceeding 10 percent.
Do not use methanolFuels 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.Fuel AdditivesHYUNDAI recommends that you use
good quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run clean-
er and enhance performance of the
Emission Control System. For more infor-
mation 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, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, add one bottle of additive to the
fuel tank at every 7,500mile or every
engine oil change is recommended.
Additives are available from your author-
ized HYUNDAI dealer along with infor-
mation on how to use them. Do not mix
other additives.
Operation in foreign countriesIf 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 offuels containing methanol.
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any gasohol 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.

ice has formed around it, tap lightly or
push on the lid to break the ice and
release the lid. Do not pry on the lid. If
necessary, spray around the lid with an
approved de-icer fluid (do not use radi-
ator anti-freeze) or move the vehicle to a
warm place and allow the ice to melt.
1. Stop the engine.
2. To open the fuel filler lid, push the fuel
filler lid opener button.
3. Pull the fuel filler lid (1) out to fully open.
4. To remove the cap, turn the fuel tank cap (2) counterclockwise.
5. Refuel as needed.

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 one time, otherwise 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.

(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.

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.
