3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise 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 re-
tighten by turning it clockwise.

(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" (automatic) 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 coun-
terclockwise 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 chap-
ter 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:
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. Al-
ways 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.

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 quan-
tity of coolant to the radiator.
5. Slowly fill the radiator with the proper coolant
mixture (see the "Recommended 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 counter-
clockwise without pressing down on it, until
it stops. This relieves any pressure remain-
ing 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.
G050D02NF-A
G050D01NF
6. Run the engine at idle until the coolant circu-
lates. 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".

CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)G110A01E-AATTransaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.NOTE:Automatic transaxle fluid is basically red in
color. As driving distance increases, the
fluid color turns darkish red gradually. It is
a normal condition and you should not
judge the need to replace based upon the
changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in
section 5.
!
G110B05A-AATRecommended FluidYour Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF SP III, DIAMOND ATF SP III, SK ATF SP
III or other brands meeting the SP III specifica-
tion approved by Hyundai Motor Co.. Damage
caused by a nonspecified fluid is not covered by
your new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may cause
damage to the automatic transaxle.
Only use HYUNDAI GENUINE ATF SP III,
DIAMOND ATF SP III, SK ATF SP III or other
brands meeting the SP III specification ap-
proved by Hyundai Motor Co.. If you are
having your vehicle serviced at a facility
other than a Hyundai dealer, verify that the
correct ATF is used for your vehicle.

Fluid Level
G100B01L
Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger to feel inside the hole. The oil
level should be at its bottom edge. If it is not,
check for leaks before adding oil. To refill the
transaxle or bring the oil level up, add oil
slowly until it reaches the proper level. Do not
overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
