Introduction
Gasoline engineUnleadedYour new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 87 or highter.
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 and
methanolGasohol, 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 than
what has been specified. (Consult
an authorized Hyundai dealer for
details.)
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol 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 Warranty
does not cover damage to the fuel
system or any performance prob-
lems caused by the use of “E85” fuel.

Introduction4 1Use of MTBEWe 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 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.
Gasolines for cleaner airTo 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 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 Warranty
may not cover damage to the fuel
system and performance problems
that are caused by the use of
methanol or fuels containing
methanol.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol or fuels
