CHECKING THE BATTERY!
G210A01A-AAT
WARNING:
Batteries can be dangerous! When
working with batteries, carefully observe
the following precautions to avoid
serious injuries.
The fluid in the battery contains a strong
solution of sulfuric acid, which is poisonous
and highly corrosive. Be careful not to spill
it on yourself or the car. If you do spill
battery fluid on yourself, immediately do
the following:
ONF078017
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical
assistance.
o If battery fluid is in your eyes, rinse out
your eyes with water and get medical
assistance as soon as possible. While
you are being driven to get medical
assistance, continue to rinse your eyes
by using a sponge or soft cloth saturated
with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk
of magnesia, eat a raw egg or drink
vegetable oil. Get medical assistance
as soon as possible.
While batteries are being charged (either
by a battery charger or by the vehicle's
generator), they produce explosive gases.
Always observe these warnings to prevent
injuries from occurring:
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking
in the area.
o Keep children away from the area.

Good Burned out CAUTION:
A burned-out fuse indicates that there is
a problem in the electrical circuit. If you
replace a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a
Hyundai dealer for diagnosis and repair.
Never replace a fuse with anything
except a fuse with the same or a lower
amperage rating. A higher capacity fuse
could cause damage and create a fire
hazard.NOTE:See page 6-36 for the fuse panel descrip-
tions.

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.

G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power
steering hose connections for fluid leakage
at those intervals specified in the vehicle
maintenance schedule in Section 5.
The power steering hoses should be
replaced if there is severe surface crack-
ing, pulling, scuffing or worn spots.
Deterioration of the hose could cause
premature failure.
POWER STEERING FLUID
LEVELG230A01NF-AAT
Recommended FluidUse PSF-4 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.
ONF078007
The power steering fluid level should be
checked regularly. To check the power
steering fluid level, be sure the engine is
"OFF", then check to make certain that the
power steering fluid level is between the
"MAX" and "MIN" level markings on the
fluid reservoir.NOTE:Grinding noise from the power steering
pump may be heard immediately after
the engine is started in extremely cold
conditions (below - 4°F). If the noise stops
during warm up, there is no abnormal
function in the system. It is due to a
power steering fluid characteristic in
extremely cold conditions.
CHECKING ELECTRIC COOLING
FANS!
G220A01A-AAT
WARNING:
The cooling fan is controlled by engine
coolant temperature and may
sometimes operate even when the
engine is not running. Use extreme
caution when working near the blades of
the cooling fan, so that you are not injured
by a rotating fan blade. As the engine
coolant temperature decreases the fan
will automatically shut off. This is a
normal condition.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on
automatically if the engine coolant
temperature is high or whenever the air
conditioning is in operation.

H010D01NF-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls
exhaust emissions while maintaining good
vehicle performance.G270301AUNVehicle modificationsThis vehicle should not be modified. Modi-
fication of your vehicle could affect its per-
formance, safety or durability and may
even violate governmental safety and
emissions regulations.
In addition, damage or performance prob-
lems resulting from any modification may
not be covered under warranty.G270302AUNEngine exhaust gas precautions
(carbon monoxide)Carbon monoxide can be present with
other exhaust fumes. Therefore, if you smell

PROPOSITION 65 WARNING:
Engine exhaust and a wide variety of
automobile components and parts, in-
cluding components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of Califor-
nia to cause cancer and birth defects
and reproductive harm. In addition, cer-
tain fluids contained in vehicles and
certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
CATALYTIC CONVERTERH020A01NF-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
H020A01NF
!
WARNING - Exhaust
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.

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.
