following classification.
API SJ, SL or ABOVE,
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.

3. Slide underneath the car and loosen
the drain plug by turning it counter-
clockwise with a wrench of the proper
size. Be sure that a drain pan is in
position to catch the oil as it drains out,
then remove the drain plug.
4. When the oil has stopped draining,
replace the drain plug using a new
gasket and retighten by turning it clock-
wise.
Oil pan drain plug tightening torque:
25.3 ~ 32.5 lb.ft (3.5 ~ 4.5 kgf.m)
HNF5006-1

(3.3L)
The engine oil and filter should be changed
at those intervals specified in the
maintenance schedule in Section 5. If the
car is being driven in severe conditions,
more frequent oil and filter changes are
required.
The procedure for changing the oil and
filter is as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let
it warm up until the needle on the coolant
temperature gauge moves above the
lowest mark. Turn the engine off and
place the gear selector lever in "P" (au-
tomatic) or reverse gear (manual
transaxle).
2. Open the hood and remove the engine
oil filler cap.NOTE:Loosen the oil filter cap by turning it
counterclockwise to drain well the oil in
the oil filter (3.3L only).
WARNING:
Be very careful when draining the engine
oil as it may be hot enough to burn you!

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:
This product contains a chemical known
to the State of California to cause cancer.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Used engine oil contains chemicals that
have caused cancer in laboratory
animals. 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.

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant
in a 50/50 mix with water. The engine
coolant should be compatible with
aluminum engine parts. Additional
corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration
and type of engine coolant to prevent
freezing and corrosion. Never allow the
concentration of antifreeze to exceed the
60% level or go below the 35% level, or
damage to the cooling system may result.
For proper concentration when adding or
replacing the engine coolant, refer to the
following table.
G050C01NF-GATTo Check the Coolant LevelThe coolant level can be seen on the side
of the plastic coolant reservoir. The level of
the coolant should be between the "L" and
"F" lines on the reservoir when the engine
is warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
it up to "F". If the level is low, inspect for
coolant leaks and recheck the fluid level
frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01NFG050D01NF-GAT
To Change the Engine CoolantThe engine coolant should be changed at
those intervals specified in the vehicle
maintenance schedule in Section 5.
CAUTION:
o Engine coolant can damage the finish
of your car. If you spill engine coolant
on the car, wash it off thoroughly with
clean water.
o The engine in your vehicle has alumi-
num engine parts and must be
protected by an ethylene-glycol base
coolant to prevent corrosion and freez-
ing.
Do not use hard water. Hard water can
cause engine damage from corro-
sion, overheating or freezing.

3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator.
Allow all the engine coolant to drain
from the cooling system, and then
securely close the drain cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then,
following the manufacturer's directions
on the engine coolant container, add
the appropriate quantity of coolant to
the radiator.
5. Slowly fill the radiator with the proper
coolant mixture (see the "Recom-
mended Engine Coolant in previous
page) until the fluid level stays up in the
radiator neck. And pump the radiator
hose in order to bleed the air.
HNF5008
2. Wrap a thick cloth around the radiator
cap and slowly turn the radiator cap
counterclockwise without pressing
down on it, until it stops. This relieves
any pressure remaining in the cooling
system. When you are sure that all the
pressure has been released, remove
the radiator cap by pushing down and
turning counterclockwise.

6. Run the engine at idle until the coolant
circulates. If the cooling fan operates
and the coolant starts to circulate, add
the coolant to the reservoir.
7. To bleed the air in the cooling system,
repeat procedure 6 until the cooling fan
operates 3~5 times.
8. Replace the radiator cap and turn it until
tightly installed. And then, add coolant
to the reservoir until the level is between
"L" and "F".
9. Stop the engine and check the coolant
level when the engine is cool. The level
of the coolant should be the "L" and "F"
lines on the reservoir. If the level is
below the "L" line, repeat the procedure
4~8 until the level between "L" and "F".

10. Replace the reservoir cap and check to
be sure the drain cock and the radiator
cap are fully closed and not leaking.
CAUTION:
Recheck after a few days and add the
coolant if the level is below the "L" level.
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 coolant 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.
CAUTION:
o Operating your vehicle without using
a proper air cleaner filter in place can
result in excessive engine wear.
o When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake. These may result
in damage to the air cleaner filter.
!
CHANGING THE AIR
CLEANER FILTERG070A03Y-AATThe replacement of the air cleaner filter is
performed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be
lifted off, the old filter removed and the
new filter put in its place.
Genuine Hyundai replacement parts are
recommended.

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.
