wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator cap by pushing down and turning coun-terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck. G050D03E

To Change the Coolant
The coolant should be changed at
those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine 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 radia- tor cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
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 appropriatequantity of coolant to the radiator.
!WARNING:
Remove the radiator cap when the
radiator is cool. 5. Start the engine, top off the radiator
with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

SPARK PLUGS

G060B02S-GAT
REPLACING THE SPARK PLUGS (Gasoline Engine)
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenances schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc. When spark plugs are replaced, al-ways use spark plugs recommended by Hyundai. The use of other spark plugs can result in loss of perfor-mance, radio interference or engine damage.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
NOTE: When replacing the spark plugs, genuine Hyundai replacement partsare recommended. Recommended Spark Plugs:
CHAMPION NGK Leaded

RC10YC4BKR5ES-11
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the cooling fan so thatyou are not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.

!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 theinsulated connector, the spark plugs or the engine itself. HGK2574. When preparing to remove the old
spark plug, guide the socket down over the spark plug, being careful not to damage the ceramic insula- tor.
5. To remove the spark plug, turn the wrench handle in a counterclock-wise direction.
6. To install the new spark plug, guide
the socket down over the sparkplug, being careful not to damage the ceramic insulator.
HGK258
3. To remove the spark plug cable,
pull straight up on the insulated connector, not the cable. Pulling on the cable may damage the car- bon core conductor.
G060C01S-GAT Changing 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 mixedup.
1. Remove the center cover on the
engine rocker cover.
2. Using a clean cloth, remove any dirt that has accumulated around the spark plug so it cannot fall intothe cylinder when the spark plug is removed. HGK256

19CHANGING THE AIR CLEANER FILTER
NOTE: Spark plugs should be tightened firmly. Over-tightening can dam-age the threads in the aluminum cylinder head. Leaving them too loose can cause the spark plugs toget 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. G070A01E-AAT

Gasoline engine
To change the filter, unsnap the clipsaround the cover. When this is done,the cover can be lifted off, the old filter removed and the new filter put in its place. Genuine Hyundai Replace-ment Parts are recommended.
!
G070A02E CAUTION:
o Operating your vehicle without a proper air filter in place can result in excessive engine wear.
o When removing the air cleaner filter, be careful that dust or dirtdoes not enter the air intake. These may result in damage tothe air cleaner filter.

A good quality washer fluid should be used to fill the washer reservoir. Thefluid level should be checked more frequently during inclement weather or whenever the washer system is inmore frequent use.The capacity of the washer reservoiris 3.0 liters (3.2 U.S. quarts).
CAUTION:
o Radiator antifreeze (engine cool- ant) should not be used in thewasher system because it will damage the car's finish.
o The washer should not be oper- ated if the washer reservoir is empty. This can damage thewasher fluid pump. WARNING:
o Windshield washer fluid agents contain some amounts of alcoholand can be flammable under cer-tain circumstances. Do not allow sparks of flame to contact the washer fluid or the washer fluidreservoir. Damage to the vehicle or its occupants could occur.
o Windshield washer fluid is poi- sonous to humans and animals.Do not drink windshield washer fluid. Serious injury or death could occur.

1. Using a wrench of the correct size,
loosen the oil filler plug by turning it counterclockwise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside the hole. The oil levelshould be at its bottom edge. If it is not, check for leaks before addingoil. To refill the transaxle or bring the oil level up,add oil slowly until it reaches the proper level. Do notoverfill.
3. Replace the plug and washer, screw it in with your fingers and then tighten securely with the wrench.

To Check the Maunal Transaxle Fluid Level
G100B01L
Park the car on level ground with the
engine off. G110B04A-AAT
Recommended Fluid
Your Hyundai automatic transaxle is
specially designed to operate with HYUNDAI GENUINE ATF SP III, DIA- MOND ATF SP-III, SK ATF SP III orother brands approved by Hundai Motor Co,. Damage caused by a nonspecified fluid is not covered byyour new vehicle limited warranty. NOTE: Automatic transaxle fluid is a 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 needto replace based upon the changing color.
You must replace the automatic
transaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section5.
!WARNING:
It is always better to check the
transaxle oil level when the engine is cool or cold. If the engine is hot, you should exercise great cautionto avoid burning yourself on hot engine or exhaust parts.

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 normaloperating temperature and the en- gine idling.
G110C01E-GAT
Transaxle Fluid Capacity
The fluid capacity of the automatic
transaxle is 6.1 liters (1.6 DOHC)/7.8 liters (1.8/2.0 DOHC). While the engine is idling, apply the brakes and move the gear selector lever from "P" to each of its other positions -- "R", "N", "D", "3" (1.8/2.0 DOHC), "2", "L" -- and then return to"N" or "P". With the engine still idling:
1. Open the hood, being careful to
keep hands, long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as faras 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. G110D01E
!WARNING:
The transaxle fluid level should be
checked when the engine is at normal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot. Exercise great care not to burn yourself during this procedure.
! CAUTION:
Use of aftermarket ATF additives
may cause damage to the auto- matic transaxle. Only use HYUNDAI GENUINE ATF SP III, DIAMOND ATF SP III, SK ATF SP III or otherbrands approved by Hyundai Mo- tor Co., If you are having your vehicle serviced at a facility otherthan a Hyundai dealer, verify that the correct ATF is used for your vehicle.
