!WARNING:
6. Start the engine, top off the radiator with water, open the hood and then add engine coolant to the reservoir until the level is between "L" and "F".
7. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.
3. Be sure your drain receptacle is inplace. Open the drain cock on the radiator. Allow all the engine coolantto drain from the cooling system, then securely close the drain cock.
4. Check Section 9 for the capacity of
the cooling system in your car. Then,following the manufacturer's direc- tions on the engine coolant contain-er, add the appropriate quantity of coolant to the radiator.
5. Fill the radiator with clean demineral-
ized or distilled water. Continue toadd clean demineralized or distilled water in small quantities until thefluid level stays up in the radiator neck. G050D02HR
!WARNING:
Do not remove the radia- tor cap when the engine and radiator are hot. Scalding hot coolant andsteam may blow out un- der pressure causing se- rious injury.The electric motor (cool- ing fan) is controlled by engine coolant tempera- ture, refrigerant pressure
and vehicle speed. It may some-times operate even when the engineis not running. Use extreme caution when working near the blades of the cooling fan so that you are not in-jured by a rotating fan blades. As the engine coolant temperature de- creases, the electric motor will auto-matically shut off. This is a normal condition.

15FILLING THE WASHER RESERVOIR
G090A02HR-GAT The washer fluid reservoir supplies fluid to the windshield washer system. 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 in morefrequent use. The capacity of the washer reservoir is 2.0 liters. HHR5016
2. Pull up the wiper blade until you hear
an audible "click" to engage in theend of the wiper arm.
NOTE: Do not allow the wiper arm to fall against the windshield. HHR5051
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 isempty. This can damage thewasher fluid pump.
!
!WARNING:
o Windshield washer fluid agents contain some amounts of alcohol and can be flammable under cer- tain circumstances. Do not allow sparks or flame to contact thewasher fluid or the washer fluid reservoir. Damage to the vehicle or its occupants could occur.
o Windshield washer fluid is poi- sonous to humans and animals.Do not drink windshield washerfluid. 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 transmission or bring the oil level up, add oil slowly until it reaches the proper level. Do notoverfill.

G120E01HR-GAT Adding Brake Fluid
WARNING:
Handle brake fluid carefully. It can damage your vision if it gets into your eyes. Use only DOT 3 or DOT 4 specification fluid from a sealedcontainer. Do not allow the fluid can or reservoir to remain open any longer than required. This will pre-vent entry of dirt and moisture which can damage the brake system and cause improper operation. To add brake fluid, pull up the cover, wipe away any dirt, and open the fluidreservoir cap. Slowly pour the recom- mended fluid into the reservoir. Do not overfill. Carefully replace the cap on thereservoir and tighten.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans. G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at a
fast idle for several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash
vents is not cold, have the air condi-tioning system inspected by your Hyundai dealer.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level maydamage the compressor.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.

G140D01A-GAT Checking the Compressor Drive Belt When the air conditioning is being used regularly, the compressor drive belt tension should be checked at leastonce a month. To check the drive belt tension, press down on the belt halfway between theengine crankshaft and compressor pulleys. Pressing with your finger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instruments to check it with a force of 98N (22 lb.), the deflection should beapprox. 8.0 mm (0.315 in.). If the belt is too loose, have it adjusted by your Hyundai dealer.

A fusible link will melt if the electrical circuits from the battery are ever over- loaded, thus preventing damage to the entire wiring harness. (This could becaused by a short in the system draw- ing too much current.) If this ever happens, have a Hyundai dealer de-termine the cause, repair the system and replace the fusible link. The fusible links are located in a fuse box for easyinspection.

Belt routing should also be checked to be sure there is no interference be-tween the belts and other parts of the engine. After a belt is replaced, the new belt should be adjusted again after twoor three weeks to eliminate slack result- ing from initial stretching after use. WARNING:
The drive belt should be checked when the engine is cool or cold to avoid burning yourself on hot en- gine.
