Introduction
Your new vehicle is designed to obtain
maximum performance with UNLEAD-
ED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
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.)
Never add any fuel system cleaning
agents to the fuel tank other than what
has been specified. (Consult an
authorized HYUNDAI dealer for
details.)Gasoline containing alcohol ormethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol) are being marketed along with or
instead of leaded or unleaded gaso-
line. For example, "E15" is a gasohol
comprised of 15% ethanol and 85%
gasoline.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
"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. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 15 percent.
✽ ✽ NOTICE
To prevent damage to your vehicle’s
engine and fuel system:
• Never use gasohol which contains
methanol.
• Never use gasohol containing more than 15% ethanol.

Your New Vehicle Limited
Warranty does not cover damage to

"E85" fuel.
FUEL REQUIREMENTS
WARNING - Refueling
• Do not "top off" after the noz- zle automatically shuts off
when refueling. 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 in the event
of an accident.
