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 eruptthrough the opening if the cap is removed. You could be seriously burned if you do not observe thisprecaution. Do not remove the radiator cap until the radiator is cool to the touch.

Use a high quality ethylene-glycol
coolant in a 50/50 mix with water.
10.Start the engine and check to be
sure no oil is leaking from thedrain plug or oil filter.
11.Shut off the engine and recheck
the oil level.
NOTE:
o It is recommended that the en- gine oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally accept-able manner. It is suggested that it be placed in a sealed container and taken to a service station formaybe reclaimation. Do not pour the oil on the ground or put it into the household trash.
WARNING:
Used motor oil may cause irrita- tion or cancer of the skin if left in contact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil.

The engine coolant should be com- patible with aluminum engine parts.Additional corrosion inhibitors or addi- tives should not be used. The cooling system must be maintained with thecorrect concentration and type of en- gine coolant to prevent freezing and corrosion. Never allow the concentra-tion of antifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system mayresult. For proper concentration when adding or replacing the engine cool- ant, refer to the following table. G050C01A-GAT
To Check the Coolant Level The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. 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 dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.

4. Turn the radiator cap counterclock-
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. G050D01FC
G050D02FC
5. Start the engine, top off the radia- tor 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 thedrain cocks are fully closed and not leaking.
G050D02A-AAT
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 park-ing brake and remove the radiator 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.

SPARK PLUGS
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition. G060A01L
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.

!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 plug 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

17CHANGING 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

When this is done, the cover can belifted off, the old filter removed andthe new filter put in its place. Genuine Hyundai Replacement Parts are rec- ommended.
!
G070A02FC 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 to the air cleaner filter.
Diesel engine
To change the filter, unsnap the clips
around the cover.

The washer fluid reservoir supplies
fluid to the windshield washer sys- tem.
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 reservoir
is 3.0 liters (3.2 U.S. quarts).

CAUTION:
o Do not operate the wipers on dry glass. This can result in more rapid wear of the wiper blades and may scratch the glass.
o Keep the blade rubber out of contact with petroleum productssuch as engine oil, gasoline, etc.
G080A02A-AAT The wiper blades should be carefully
inspected from time to time and cleaned to remove accumulations ofroad film or other debris. To clean the wiper blades and arms, use a clean sponge or cloth with a mild soap ordetergent and water. If the wipers continue to streak or smear the glass, replace them with genuine Hyundaireplacement parts or their equivalent. HEF119

CAUTION:
o Radiator antifreeze (engine cool- ant) should not be used in the washer system because it will damage the car's finish.
o The washer should not be oper- ated if the washer reservoir isempty. This can damage the washer fluid pump.
