Your Hyundai should not be modified in any way. Such modifications may adversely affect the per-
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, a Tire Pressure Monitoring System, and other
electronic components. It is possible for an improperly installed/adjusted two-way radio or cellular tele-
phone to adversely affect electronic systems. For this reason, we recommend that you carefully fol-
low the radio manufacturer's instructions or consult your Hyundai dealer for precautionary measures
or special instructions if you choose to install one of these devices.

Introduction
Gasoline engine
Unleaded
Your new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 87 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 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 driveability 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. "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.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning
agents to the fuel tank other thanwhat has been specified. (Consultan authorized Hyundai dealer for details.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs dri-vability.WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks, oth- erwise the Check Engine
light will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuelsystem or any performance prob-lems caused by the use of “E85” fuel.

Use of MTBE
We recommend that fuels containing
MTBE (Methyl Tertiary Butyl Ether) over
15.0% vol. (Oxygen Content 2.7%
weight) should not be used in your vehi-
cle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
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.
Gasolines for cleaner air
To help contribute to cleaner air, we rec-
ommend 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.
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 performance problemsthat are caused by the use of methanol or fuels containingmethanol.
CAUTION
Your New Vehicle Limited Warranty may 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.)

WARNING - Refueling
If pressurized fuel sprays out, it
can 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 " " light will illumi-
nate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

If the fuel-filler lid will not open because
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.
