gasoline and 10% ethanol or grain alcohol)
may be used in your Hyundai. However, if
your engine develops driveability
problems, the use of 100% unleaded
gasoline is recommended. Fuels with
unspecified quantities of alcohol, or
alcohols other than ethanol, should not be
used.

CATALYTIC CONVERTERH020A01A-AAT(If Installed)Hyundai vehicle is equipped with a mono-
lith type three-way catalytic converter to
reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the
exhaust gas. Exhaust gases passing
through the catalytic converter cause it to
operate at a very high temperature. The
introduction of large amounts of unburned
gasoline into the exhaust may cause the
catalytic converter to overheat and create
a fire hazard. This risk may be reduced by
observing the following:Catalytic Converter
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic
converter temperatures can result
from improper operation of the
electrical, ignition or multiport
electronic fuel injection.
o If your engine stalls, pings, knocks, or
is hard to start, have your Hyundai
dealer inspect and repair the problem
as soon as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause
the engine to misfire and result in
damage to the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause
the catalytic converter to overheat
and create a fire hazard.
o Do not touch the catalytic converter
or any other part of the exhaust system
while the catalytic converter is hot.
Shut off the engine, wait for at least
one hour before touching the cata-
lytic converter or any other part of the
exhaust system.

o Remember that your Hyundai dealer
is your best source of assistance.
o Do not stop your Hyundai over any
combustible material such as grass,
paper, leaves or rags. These materials
might contact the hot catalytic
converter and a fire might result.
