CATALYTIC CONVERTER

H020A01A-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.
