D060D02A-AAT3. Loosen Wheel NutsD060E01A-AAT4. Put the Jack in Place
The wheel nuts should be loosened slightly
before raising the car. To loosen the nuts, turn
the wrench handle counterclockwise. When
doing this, be sure that the socket is seated
completely over the nut so it cannot slip off. For
maximum leverage, position the wrench so the
handle is to the left as shown in the drawing.
Then, while holding the wrench near the end of
the handle, push down on it with steady pres-
sure. Do not remove the nuts at this time. Just
loosen them about one-half turn.The base of the jack should be placed on firm,
level ground. The jack should be positioned as
shown in the drawing.
D060F02E-AAT5. Raising the Car
After inserting a bar into the wheel nut wrench,
install the bar into the jack as shown in the
drawing. To raise the vehicle, turn the wheel nut
wrench clockwise. As the jack begins to raise
the vehicle, double check that it is properly
positioned and will not slip. If the jack is on soft
ground or sand, place a board, brick, flat stone
or other object under the base of the jack to keep
it from sinking.
Raise the car high enough so that the fully
inflated spare tire can be installed. To do this,
you will need more ground clearance than is
required to remove the flat tire.

Lower the car to the ground by turning the jack
handle counterclockwise. Then position the
wrench as shown in the drawing and tighten the
wheel nuts. Be sure the socket is seated com-
pletely over the nut. Do not stand on the wrench
handle or use an extension pipe over the wrench
handle.
Go around the wheel tightening every other nut
until they are all tight. Then double-check each
nut for tightness and reinstall the wheel cover.
After changing wheels, have a technician tighten
the wheel nuts to their proper torque as soon as
possible.
Wheel nut tightening torque:Steel wheel & aluminium alloy wheel:
65-80 lb.ft (900-1,100 kg.cm)If you have a tire gauge, remove the valve cap
and check the air pressure. If the pressure is
lower than recommended, drive slowly to the
nearest service station and inflate to the correct
pressure. If it is too high, adjust it until it is correct.
Always reinstall the valve cap after checking or
adjusting tire pressure. If the cap is not re-
placed, air may leak from the tire. If you lose a
valve cap, buy another and install it as soon as
possible.
After you have changed wheels, always secure
the flat tire in its place in the trunk and return the
jack, jack handle, and tools to their proper
storage locations.
CAUTION:Your car can be damaged if towed incor-
rectly!
If your car has to be towed, it should be done by
your Hyundai dealer or a commercial tow truck
service. This will help assure that your car is not
damaged in towing. Also, professionals are
generally aware of state and local laws govern-
ing towing. In any case, rather than risk damage
to your car, it is suggested that you show this
information to the tow truck operator. Be sure
that a safety chain system is used and that all
state and local laws are observed.

!WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
G040A02A-AATCHANGING THE OIL AND FILTERG030D01A-AATAdding Oil
If the oil level is close to or below the "L" mark,
add oil until it reaches the "F" 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 "F" and "L" marks is
equal to about 1 quart of oil.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). Set the parking
brake.
2. Open the hood and remove the engine oil
filler cap.
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 washer and
retighten by turning it clockwise.
Tightening torque is: 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 is: 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. 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.G050A01A-AATCHECKING AND CHANGING THE EN-
GINE COOLANT
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.
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.
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.

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 counterclock-
wise.
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.
5. Start the engine, top off the radiator with
water and then add 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.G060A02Y-AATSPARK PLUGS
Your engine was originally equipped with plati-
num-tipped spark plugs.
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.
WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. 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 de-
creases, the fan will automatically shut off.
This is a normal condition.

Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance 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, always use
the genuine parts recommended.

G060C04Y-AATChanging the Spark Plugs
You 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.
1. Remove the center (2.4 L) cover on the
engine rocker cover.
NOTE:It is recommended that the spark plugs (For
2.7L Engines) should be changed by an
authorized Hyundai dealer.
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.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.
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.
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.
5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
NOTE:Spark plugs should be tightened to speci-
fication. Over-tightening can damage the
threads in the aluminum cylinder head.
Also, leaving them too loose can cause the
spark plug 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.
