3. Exhaust Emission Control
System
The Exhaust Emission Control Sys-
tem is a highly effective system which
controls exhaust emissions while
maintaining good vehicle performace.
H010E01Y-GAT
(If installed)
This system helps control nitrogen
oxides by recirculating a part of the
exhaust gas into the engine, thereby
reducing cylinder combustion tem-
perature.
H020A02A-AAT
; For a Gasoline Engine
(If installed)
Hyundai vehicles are equipped with a
monolith type three-way catalytic con-
verter to reduce the carbon monoxide,
hydrocarbons and nitrogen oxides con-
tained in the exhaust gas. Exhaust
gases passing through the catalytic
converter may cause it to operate at a
very high temperature. The introduc-
tion of large amounts of unburned gaso-
line into the exhaust may cause the
catalytic converter to overheat and
create a fire hazard. This risk may be
reduced by observing the following:

WARNING:
o Use unleaded fuel only.
o Maintain the engine in good
operating condition. Extremely
high catalytic converter tempera-
tures can result from improper
operation of the electrical, igni-
tion 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 gaso-
line may cause the engine to
misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for peri-
ods 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 cre-
ate a fire hazard.
o Do not touch the catalytic con-
verter or any other part of the
exhaust system while the cata-
lytic 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 park, idle or drive your
vehicle over any combustible ma-
terial such as grass, paper, leaves
or rags. These materials might
contact the hot catalytic converter
and a fire might result.
H020D01S-GAT
; For a Diesel Engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter
to reduce the carbon monoxide, hy-
drocarbons and particulate contained
in the exhaust gas.
