CHECKING THE ENGINE OILG030B01O-AATRecommended OilThe engine oil quality should meet the
following classification.
API SL or SM,
ILSAC GF-3 or ABOVE
G030B01JM-U G030A01A-AAT
Engine oil is essential to the performance
and service of the engine. It is suggested
that you check the oil level at least once a
week in normal use and more often if you
are on a trip or driving in severe conditions.

G030C01JM-AATTo Check the Oil Level
Before checking the oil, warm up the engine
to the normal operating temperature and
be sure your car is parked on level ground.
Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and
withdraw it again. Then note the highest
level the oil has reached on the dipstick. It
should be between the upper ("F") and
lower ("L") range.
!
WARNING:
Be very careful not to touch the radiator
hose when checking the engine oil as it
may be hot enough to burn you.

G030C02NF
(2.4L)
(3.3L)
NOTE:o For good fuel economy, SAE 5W-20
(5W-30), ILSAC GF-3 engine oil is
preferred.
o If SAE 5W-20, ILSAC GF-3 engine oil is
not available, a secondary recom-
mended engine oil for corresponding
temperature range can be used. See
page 9-4

CHECKING AND CHANGING THE
ENGINE COOLANT!
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and
may erupt through the opening if the cap
is removed. You could be seriously
burned if you do not observe this
precaution. Do not remove the radiator
cap until the radiator is cool to the touch.
!
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the
proper size. A certain amount of oil will
come out when you remove the filter. So be
sure to have your drain pan in place
underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter
itself. Do not over-tighten.
Tightening torque:
8.7 ~ 11.6 lb.ft (1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Remove the engine oil level dipstick.
8. Refill the crankcase with the recommended
engine oil. Refer to the specification in
chapter 9 for engine oil capacity.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It
is suggested that it be placed in a sealed
container and taken to a service station
for reclamation. Do not pour the oil on the
ground or put it into the household trash.
PROPOSITION 65 WARNING:
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.
!
9. Start the engine and check to be sure no
oil is leaking from the drain plug or oil
filter.
10. Shut off the engine and recheck the oil
level.

CAUTION:
o Radiator antifreeze (engine coolant)
should not be used in the washer
system because it will damage the
car's finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This
can damage the washer fluid pump.
!
A good quality washer fluid should be
used to fill the washer reservoir. The fluid
level should be checked more frequently
during bad weather or whenever the
washer system is in more frequent use.
The capacity of the washer reservoir is 3.2
U.S. quarts (4.0 liters).
!
WARNING:
It is always better to check the transaxle
oil level when the engine is cool or cold.
If the engine is hot, you should exercise
great caution to avoid burning yourself
on hot engine or exhaust parts.
CHECKING THE TRANSAXLE
OIL (MANUAL)G100A02NF-AAT

Filler plug
Drain plug
Transaxle lubricant in the manual transaxle
should be checked at those intervals
specified in the vehicle maintenance
schedule in Section 5.Recommended OilUse only HYUNDAI GENUINE PARTS MTF
75W/85 (API GL-4) in the manual transaxle.Manual Transaxle Oil CapacityThe oil capacity of the manual transaxle is
1.8 U.S. quarts (1.75 liters).
!
WARNING:
o Windshield washer fluid agents con-
tain some amounts of alcohol and can
be flammable under certain circum-
stances. Do not allow sparks or flame
to contact the washer fluid or the
washer fluid reservoir. Damage to
the vehicle or its occupants could
occur.
o Windshield washer fluid is poisonous
to humans and animals. Do not drink
windshield washer fluid. Serious injury
or death could occur.
NOTE:It is recommended that the manual
transaxle fluid should be checked by an
authorized Hyundai Dealer.

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.

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.
