CHANGING THE OIL AND FILTER
The engine oil and filter should be changed at those intervals specified in the maintenanceschedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges are required. The procedure for changing the oil and filter is as follows:
1. Park the car on level ground and set the parking brake. Start the engine and let itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
G040A01GK 3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with a wrench of the proper size. Be surethat a drain pan is in position to catch the oilas it drains out, then remove the drain plug.
WARNING: Be very careful when draining the engine oil as it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer and retighten by turning it clockwise. Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L) 4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of the proper size. A certain amount of oil willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filteritself. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.Be sure that the mounting surface on the engine is clean and that the old gasket isremoved completely. Lubricate the new gas-ket on the filter with clean engine oil beforeinstallation.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should consume
some engine oil while normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders.
o A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generatedduring engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Moreengine oil may be consumed under severedriving conditions such as high speeds, fre-quent acceleration and deceleration, com-pared to normal driving condition. V6

6-8 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 bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck.
G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenanceschedule in Section 5.
NOTE: 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 park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
G050D01A
5. Start the engine, top off the radiator withwater 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 fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

To Check the Transaxle Fluid Level
HGK174
Park the car on level ground with the parking brake engaged. When the transaxle fluid levelis checked, the transaxle fluid should be atnormal operating temperature and the engineidling.
G110C02Y-GAT
Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is 7.8 liters (8.2 U.S. quarts). 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 duringthis procedure.
G100B02A-AAT
To Check the Manual Transaxle Fluid Level
SSA6100B
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 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 bottomedge. If it is not, check for leaks beforeadding oil. To refill the transaxle or bring theoil level up,add oil slowly until it reaches theproper level. Do not overfill.
3. Replace the plug and washer, screw it in with your fingers and then tighten securelywith the wrench. G110A02A-AAT CHECKING THE TRANSAXLE FLUID (AUTOMATIC) Transaxle fluid in the automatic transaxle should be checked at those intervals specified in thevehicle maintenance schedule in Section 5. NOTE: Basically automatic transaxle fluid is red color. As driving distance increases, thefluid color turns darkish red gradually. It isnormal condition and you should not usefluid color as a criterion for replacing thetransaxle fluid. You must replace the automatic transaxle fluid in accordance with intervals specifiedin the vehicle maintenances schedule insection 5. G110B03A-AAT
Recommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with DIAMOND ATF SP-III or SK ATF SP-III. Damage caused by anonspecified fluid is not covered by your newvehicle limited warranty.

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" — andthen return to "N" or "P". With the engine stillidling:
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 far as it will go, thenremove it again. Now check the fluid level onthe dipstick. It should be in the "HOT" rangeon the dipstick.
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.Do not overfill. WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan, so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. Fluid level should be within this range

G140D01S-GAT Checking the Compressor Drive Belt When the air conditioning is being used regular- ly, the compressor drive belt tension should bechecked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaftand compressor pulleys. Pressing with yourfinger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instru-ments to check it with a force of 98N (22 lb.),the deflection should be approx. 8.0 mm (0.315inches). If the belt is too loose, have it adjustedby your Hyundai dealer.A/C

1. Start the engine and let it run at 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 conditioning systeminspected by your Hyundai dealer.
CAUTION: Running the air conditioning system for
extended periods of time with a low refriger- ant level may damage the compressor.
