G030A01A-AAT CHECKING THE ENGINE OIL Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal useand more often if you are on a trip or driving in severe conditions. G030B01A-GAT Recommended Oil
G030B01L
SH, SG or SG/CD (API) multi-grade and fuel efficient oil is recommended. NOTE: SAE 5W-20 is not recommended for sustained high speed vehicle operation.G030C02A-AAT
To Check the Oil Level
Before checking the oil, warm up the
engine to the normal operating tem- perature and be sure your car is parked on level ground. Turn the en-gine off.
Wait five minutes, then remove the
dipstick, wipe it off, fully reinsert thedipstick and withdraw it again. Thennote the highest level the oil has reached on the dipstick. It should be between the upper ("FULL") and lower("LOW") range. HXG094J
G030D01A-GAT
Adding Oil
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 counterclockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L"
marks is equal to about 1 liter of oil.

CHANGING THE OIL AND FIL- TER 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 theneedle on the coolant temperature gauge moves above the lowest mark. Turn the engine off and placethe gear selector lever in "P" (auto- matic) or reverse gear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the drain plug by turning it counter-clockwise with a wrench of theproper size. Be sure that a drain pan is in position to catch the oil as it drains out, then remove the drainplug.
WARNING:
Be very careful when draining theengine oil as it may be hot enoughto burn you!
The engine oil and filter should be
changed at those intervals specified in the maintenance schedule in Sec- tion 5. If the car is being driven insevere conditions, more frequent oil and filter changes are required. G040A01L

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricating and cooling the inside ofthe engine.
Engine oil consumption It is normal that an engine shouldconsume some engine oil while nor-
mal driving. The cause of oil con- sumption in a normal engine are as follows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders.A thin film of oil is left on thecylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber. This oil with some oil of the cylin- der wall is burned by the high tem- perature combustion gases duringthe combustion process.
o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine
oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and deceleration than normal driv- ing condition.

4. When the oil has stopped draining,
replace the drain plug using a new washer and retighten by turning itclockwise. Oil pan drain plug tightening torque : 3.5 ~4.0 kgf.m
5. Remove the oil filter by turning it counterclockwise with a oil filter wrench of the proper size. A cer- tain amount of oil will come out when you remove the filter. So besure to have your drain pan in place underneath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filter itself. Do not over-tighten. Oil filter tightening torque : 1.2 ~ 1.6 kgf.m Be sure that the mounting surface on the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean engine oil beforeinstallation. 7. Refill the crankcase with the rec-
ommended engine oil. Refer to thespecification in chapter 9 for en-gine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE: Always dispose of used engine oil
in an environmentally acceptable manner. It is suggested that it beplaced in a sealed container and taken to a service station for recla- mation. Do not pour the oil on theground or put it in with the house- hold 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. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE COOLANT
WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolantis under pressure and may erupt through the opening if the cap is removed. You could be seriouslyburned if you do not observe this precaution. Do not remove the ra- diator cap until the radiator is coolto the touch.

G050D02A-AAT To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec-tion 5.
CAUTION:
Engine coolant can damage thefinish 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 parking 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 coolant to drain from the cooling system,then securely close the drain cock.
Use a high quality ethylene-glycol
coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion.
Never allow the concentration of an-
tifreeze to exceed the 60% level or gobelow the 35% level or damage to thecoolant system may result. For proper concentration when adding or replac- ing the engine coolant, refer to thefollowing table.

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.Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D01L
G050D02L
5. Start the engine, top off the radia- tor with water and then add enginecoolant to the reservoir until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir
caps and check to be sure thedrain cocks are fully closed and not leaking.
WARNING:
The cooling fan is controlled by
engine coolant temperature andmay 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 a

Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage.
NOTE:
o When replacing the spark plug, Genuine Hyundai ReplacementParts are recommended. Recommended Spark Plugs:
NOTE: Do not clean or regap platinum- tipped spark plugs.
o Spark plugs should be tightenedfirmly. Overtightening can dam- age the threads in the aluminum cylinder head. Also, leavingthem too loose can cause the spark plug to get very hot and possibly result in damage to theengine.
o It is recommended that spark
plugs be changed by an autho-rized Hyundai dealer.
