WARNING:
o Your vehicle is designed to operate
with a catalytic converter and remov-
ing it will cause the engine to operate
poorly and fuel economy to drop along
with an increase in the vehicle emis-
sions.
o Remember that your Hyundai dealer
is your best source of assistance.
o Do not park, idle or drive your vehicle
over or near flammable objects such
as grass, paper, leaves or rags. These
materials might contact the hot cata-
lytic converter and a fire might result.
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.
