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.

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-GATChanging 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.
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-11!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.

!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.

12CHECKING THE TRANSAXLE
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.

!
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.

ing pins on both sides of the glove box.
G140C01A-AAT
Lubrication
To lubricate the compressor and the seals in the
system, the air conditioner should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air con-
ditioning system is not otherwise in use.
G140B01A-AAT
Checking the Air Conditioner Opera-
tion
1. Start the engine and let it run at fast idle for
several minutes with the air conditioner set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for ex-
tended periods of time with a low refrigerant
level may damage the compressor.
