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
: 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 gas-
ket on the filter before installation with clean
engine oil.7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil
level.NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-
gested that it be placed in a sealed container
and taken to a service station for reclama-
tion. Do not pour the oil on the ground or put
it in with the household trash.
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 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.
!PROPOSITION 65 WARNING:Used engine oil may cause irritation or can-
cer of the skin if left in contact with the skin
for prolonged periods of time. Used engine
oil contains chemicals that have caused can-
cer in laboratory animals. Always protect
your skin by washing your hands thoroughly
with soap and warm water as soon as pos-
sible after handling used oil.

6CHECKING AND CHANGING
THE ENGINE COOLANT
!
G050A01A-AAT G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts. Ad-
ditional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type of
engine coolant to prevent freezing and corro-
sion.
Never allow the concentration of antifreeze to
exceed the 60% level or go below the 35% level
or damage to the coolant system may result. For
proper concentration when adding or replacing
the coolant, refer to the following table.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 re-
moved. You could be seriously burned if you
do not observe this precaution. Do not re-
move the radiator cap until the radiator is
cool to the touch.

To Check the Coolant Level
The 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 cool. If the level is
below the "L" mark, add engine coolant to bring
it up between "L" and "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 diag-
nosis of the reason.

To Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.
2. 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, then securely close the drain cock.
3. 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.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
G050D01AG050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "L" and
"F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.

!WARNING:It is recommended that the engine be cool or
cold when changing the spark plugs. If the
engine is hot, you could burn yourself on the
insulated connector, the spark plug or the
engine itself.
G060C02A-D
4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator.
6. To install the new spark plug, guide the
socket down over the spark plug, being care-
ful not to damage the ceramic insulator.
5. To remove the old spark plug, turn the wrench
handle in a counterclockwise direction.
G060C03A-D
3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
NOTE:Spark plugs should be tightened firmly. Over-
tightening can damage the threads in the
aluminum cylinder head. Also, leaving them
too loose can cause the spark plugs to get
very hot and possibly result in damage to the
engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.

11CHECKING THE TRANSAXLE OIL
(MANUAL)FILLING THE WASHER RESERVOIR
G090A01A-AAT
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during inclement weath-
er or whenever the washer system is in more
frequent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).
CAUTION:o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer should not be operated if the
washer reservoir is empty. This can dam-
age the washer fluid pump.

FLUID (AUTOMATIC)
!
G110A01E-AAT
Transaxle 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 a red
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 chang-
ing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in sec-
tion 5.
G110B03A-AATRecommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF, DIAMOND ATF SP-III or SK ATF SP-III.
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
G110C02A-AAT
Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
6.45 U.S. quarts (6.1 liters).
WARNING:The transaxle fluid level should be checked
when the engine is at normal operating tem-
perature. This means that the engine, radia-
tor, exhaust system etc., are very hot. Exer-
cise great care not to burn yourself during
this procedure. 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 or suitable tool 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.

its other positions -- "R", "N", "D", "2", "L" -- and
then return to "N" or "P". With the engine still
idling:
1. Open the hood, being careful to keep hands,
hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.
G110D03A G110D02A-AAT
To Check the Transaxle Fluid Level
Park the car on level ground with the parking
brake engaged. When the transaxle fluid level is
checked, the transaxle fluid should be at normal
operating temperature and the engine idling.

3. If the transaxle fluid level is low, use a funnel
to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.
G110D04A
Fluid level should be within
"HOT" range
WARNING:The cooling fan is controlled by the engine
coolant temperature and may sometimes op-
erate 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 con-
dition.

15CHECKING THE CLUTCH FLUID
!
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT 3
or DOT 4 specification should be used. The
reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your
eyes. It will also damage your vehicles paint
if spilled on it and not removed immediately.
G130A01A-AAT
To Check the Clutch Fluid
The clutch fluid level in the master cylinder
should be checked when performing other un-
der hood services. The system should be
checked for leakage at the same time.
Check to make certain that the clutch fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir. Fill as required. Fluid loss
indicates a leak in the clutch system which
should be inspected and repaired immediately.
Consult your Hyundai dealer.

AIR CONDITIONER CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioner condenser (and engine ra-
diator) should be checked periodically for accu-
mulation of dirt, dead insects, leaves, etc. These
can interfere with maximum cooling efficiency.
When removing such accumulations, brush or
hose them away carefully to avoid bending the
cooling fans.
