G030A01A-AATCHECKING THE ENGINE OIL
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.
G030B01A-AATRecommended Oil
SH, SG or SG/CD (API) multi-grade and fuel
efficient oil is recommended.
G030A02AG030C02A-AAT
To Check the Oil Level
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it
is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-
draw it again. Then note the highest level the oil
has reached on the dipstick. It should be be-
tween the upper ("FULL") and lower ("LOW")
range.
G030D01A-AATAdding Oil
If the oil level is close to or below the "LOW"
mark, add oil until it reaches the "FULL" mark.
To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "FULL" and "LOW"
marks is equal to about 1 quart of oil.

WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace
the drain plug using a new washer and re-
tighten by turning it clockwise.
Oil pan drain plug tightening torque:
3.5 ~ 4.5 kgf.m
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.
WARNING:Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin
for prolonged periods of time. Wash your
hands thoroughly with soap and warm water
as soon as possible after handling used oil.

G050A01A-AATCHECKING AND CHANGING THE EN-
GINE COOLANTG050B01A-AATRecommended 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.

G050C01A-AATTo 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 "LOW" and "FULL" lines
on the reservoir when the engine is cool. If the
level is below the "LOW" mark, add engine
coolant to bring it up between "LOW" and "FULL".
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.

G050D02A-AATTo 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.
G050D01A
G050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "LOW"
and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant 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 con-
dition.

G060B01A-AATREPLACING THE SPARK PLUGS
G060A01L
0.039 ~ 0.043 in.
(1.0 ~ 1.1 mm )
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in section 5, or whenever engine per-
formance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, genuine
Hyundai replacement parts are recom-
mended.
G060C01S-GAT
Changing the Spark PlugsYou will find it easier to change spark plugs if the
engine is cold. Always change one spark plug at
a time. This helps avoid getting the wires mixed
up.
G060C01A-D
1. Remove the center cover on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when
the spark plug is removed.
Recommended Spark Plugs:
CHAMPION : RC10YC4
NGK : BKR5ES-113. 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.
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

6. To install the new spark plug, guide the
socket down over the spark plug, being care-
ful not to damage the ceramic insulator.
G070A02Y-AATCHANGING THE AIR CLEANER FILTER
The replacement of air cleaner filter is per-
formed 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 recom-
mended. 5. To remove the old spark plug, turn the wrench
handle in a counterclockwise direction.
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.
G070A01A
CAUTION:Operating your vehicle without a proper air
filter in place can result in excessive engine
wear.

G090A01A-AATFILLING THE WASHER RESERVOIR
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 fre-
quent 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 lever should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.
