Before checking the oil, warm up the engine to
the normal operating temperature and be sure your car is parked on level ground. Turn theengine off.
Wait a minute, then remove the dipstick, wipe it
off, fully reinsert the dipstick and withdraw itagain. Then note the highest level the oil hasreached on the dipstick. It should be betweenthe upper ("FULL") and lower ("LOW") range. If the oil level is close to or below the "L" mark,add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise. The distance between the "F" and "L" marks is equal to about 1 liter of oil. G350A01A-GAT
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. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder. High negative pressure generated
during 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. Theengine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.

CHANGING THE OIL AND FILTER 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 andretighten by turning it clockwise. 6. First, remove the vehicle number plate. Un-
screw the tapping screws (4EA) and re-move the front bumper grille.

The engine oil and filter should be changed at
those intervals specified in the maintenance schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes 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 it warm up until the needle on the coolanttemperature gauge moves above the lowest
mark. Turn the engine off and place the gearselector lever in "P" (automatic transaxle) orreverse gear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.

CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, theengine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch.
8. Before installing the new oil filter on the engine, apply clean engine oil to the surface of the rubber gasket. Temporarily tighten the oil filter by hand.

o If you aren't sure how to use, consult your Hyundai dealer.
10. Refill the crankcase with the recommended engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
11. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
12. Shut off the engine and recheck the oil level. NOTE: Always dispose of used engine oil in an
environmentally acceptable manner. It is sug- gested that it be placed in a sealed container
and taken to a service station for reclama-tion. Do not pour the oil on the ground orput it into the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil.

Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Ad-ditional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% levelor damage to the coolant system may result. Forproper concentration when adding or replacingthe coolant, refer to the following table.
35% 40%50%60% G050C01A-AAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on thecar, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
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.

REPLACING THE SPARK PLUGS
The spark plugs should be changed at the
intervals specified in the vehicle maintenance schedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plug, always use
the genuine parts recommended.
G050D02X
5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
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 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.

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 wiresmixed up.
1. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed. WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourselfon the insulated connector, the spark plugor the engine itself.
3. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
4. To remove the old spark plug, turn the wrench handle in a counterclockwise direc-tion.
5. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator.

FILLING THE WASHER RESERVOIR
The washer fluid reservoir supplies fluid to the
windshield washer system. A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be checked more frequently during bad weather orwhenever the washer system is in more fre-quent use.
The capacity of the washer reservoir is 2.5
liters (2.63 U.S. quarts).
CAUTION:
o Radiator antifreeze (engine coolant) should not be used in the washer systembecause it will damage the car's finish.
o The washer lever should not be pulled and the washer should not be operated ifthe washer reservoir is empty. This candamage the washer fluid pump.

CHANGING THE AIR CLEANER FIL- TER G080A02A-AAT
WINDSHIELD WIPER BLADES The wiper blades should be carefully inspected from time to time and cleaned to remove accu-mulations of road film or other debris. To cleanthe wiper blades and arms, use a clean spongeor cloth with a mild soap or detergent and water.If the wipers continue to streak or smear theglass, replace them with Genuine HyundaiReplacement Parts or their equivalent. 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 products such as engineoil, gasoline etc.
To change the filter, loosen the clamps (1) on
the cover. When this is done, the cover can be
lifted off, the old filter removed and the new filterput in its place. Genuine Hyundai replacement
parts are recommended.
CAUTION: Operating your vehicle without a proper air
filter in place can result in excessive engine wear.
