!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extreme caution when working near theblades of the cooling fan so that you are not injured by a rotating fan blade. As the engine coolant tem-perature decreases, the fan will auto- matically shut off. This is a normal condition.
6. Start the engine, top off the radiator
with water, open the hood and thenadd 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.

Park the car on level ground with the engine off.
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.
3. Replace the plug and washer, screw
it in with your fingers and then tightensecurely with the wrench. G130A01HR-GAT

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 a suitable tool to feel inside the
hole. The oil level should be within 14mm from its bottom edge. If it is not, check for leaks before adding oil. Torefill the rear axle 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 tightensecurely with the wrench.

G120B01A-AAT Checking the Brake Fluid Level
! CAUTION:
Because brakes are essential to the safe operation of the car, it is sug- gested that they be checked andinspected by your Hyundai dealer. The brakes should be checked and inspected for wear at those inter-vals specified in the vehicle mainte- nance schedule in Section 5.
WARNING:
Use caution when handling brake fluid. It can damage your vision if it gets into your eyes. It will also dam- age your vehicle's paint if spilledon it and not removed immediately.
G120C02A-AAT Recommended Brake Fluid Use only hydraulic brake fluid con- forming to DOT 3 or DOT 4 specifica-tions in your braking system. Follow the instructions printed on the con- tainer. G120D01A-AAT To Check the Fluid Level

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.
The fluid level in the brake fluid reser- voir should be checked periodically. The level should be between the "MIN"and "MAX" marks on the side of the reservoir. If the level is at or below the "MIN" mark, carefully add fluid to bringit up to "MAX". Do not overfill.

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 yourHyundai dealer.
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.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor. Crankshaft pulley
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.

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.
