WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away
from the battery.
Hydrogen, which is a highly
combustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the reach
of children because batteries
contain highly corrosive SUL-
FURIC ACID. Do not allow bat-
tery acid to contact your skin,
eyes, clothing or paint finish.
If any electrolyte gets into your
eyes, flush your eyes with
clean water for at least 15 min-
utes and get immediate medi-
cal attention. If possible, con-
tinue to apply water with a
sponge or cloth until medical
attention is received.
If electrolyte gets on your skin,
thoroughly wash the contacted
area. If you feel a pain or a
burning sensation, get medi-
cal attention immediately.Wear eye protection when
charging or working near a bat-
tery.
Always provide ventilation
when working in an enclosed
space.
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulation.
o When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak, resulting in
personal injury. Lift with a battery
carrier or with your hands on opposite
corners.
o Never attempt to charge the battery
when the battery cables are con-
nected.
o The electrical ignition system works
with high voltage.
Never touch these components with
the engine running or the ignition
switched on.

WARNING:

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.
