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 (Gaso- line Engine/Diesel Engine (2.5 TCI))/ 1.4 liters (Diesel Engine (2.9 CRDi))of oil. G350A01A-GAT
ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume 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 movesdownwards in the cylinder. High negative pressure generated dur- ing engine operation sucks someof 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 viscosityand quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.

10CHANGING THE ENGINE OIL AND FILTER
!
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 in severe conditions, more frequent oiland 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 coolant temperature gauge moves above the lowestmark. Turn the engine off and place the gear selector lever in "P" (auto- 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 gasket and retighten by turning itclockwise. Oil pan drain plug tightening torque: 3.5 ~ 4.5 kgf.m

11CHECKING AND CHANG- ING THE ENGINE COOL- ANT
!
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the engine is hot. When the engine is hot, the engine coolant is underpressure and may erupt through the opening if the cap is removed. You could be seriously burned if you donot observe this precaution. Do not remove the radiator cap until the radiator is cool to touch.
!
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 cartonor on the filter itself. Do not over- tighten (Tightening torque: Gaso-
line- 1.2 ~ 1.6 kgf.m, Diesel - 2.3 ~ 2.5 kgf.m) . Be sure that the
mounting surface on the engine is clean and that the old gasket is removed completely. Lubricate the new gasket on the filter with cleanengine oil before installation.
7. Remove the engine oil level dip- stick.
8. Refill the crankcase with the rec- ommended engine oil slowly. Referto the specification in chapter 9 for engine oil capacity.
! CAUTION:
Slowly pour the recommended oil by using a funnel. Do not overfill not to damage the engine. 9. Start the engine and check to be
sure no oil is leaking from thedrain plug or oil filter.
10.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 be placed in a sealed container andtaken to a service station for recla- mation. Do not pour the oil on the ground or put it into the house-hold trash.
WARNING:
Used motor oil may cause irrita-
tion or cancer of the skin if left incontact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil.

To Check the Coolant Level
The coolant level can be seen on the
side of the plastic coolant reservoir. The level of the coolant should be between the "LOW" and "FULL" lines on the reservoir when the engine iscool. If the level is below the "LOW" mark, add engine coolant to bring it up between "LOW" and "FULL". If thelevel is low, inspect for coolant leaks and recheck the fluid level frequently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosis of the reason. G050D02HP-GAT 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 the fin-ish of your car. If you spill enginecoolant on the car, wash it off thor- oughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
G050B01A-DAT Recommended Engine Coolant Use a high quality ethylene-glycol cool- ant in a 50/50 mix with water. Theengine coolant should be compatible with aluminum engine parts. Addi- tional corrosion inhibitors or additivesshould not be used. The cooling sys- tem must be maintained with the cor- rect concentration and type of enginecoolant to prevent freezing and corro- sion. Never allow the concentration of antifreeze to exceed the 60% level orgo below the 35% level, otherwise damage to the cooling system may result. For proper concentration whenadding or replacing the engine cool- ant, refer to the following table.

NOTE: Gasoline Engine Only Before adding the coolant to the radiator, unscrew the bolts on theengine cover, remove the engine cover and unscrew the flange bolt for fitting water outlet to escapethe excess pressure. And if the coolant overflows from the hole while adding the coolant, screwthe bolt and continue to add the coolant.
G050D01HP 2. 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 capby pushing down and turning coun- terclockwise.
3. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys-tem, then securely close the drain cock. HHP5006

4. Check Section 9 for the capacity of
the cooling system in your car. Then, following the manufacturer’s directions on the engine coolant container, add the appropriate quan-tity of coolant to the radiator.
5. Fill the radiator with clean deminer-
alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck.

14CHANGING THE AIR CLEANER FILTER
!
6. Start the engine, top off the radiator
with water and then add coolant to the reservoir until the level is be- tween "LOW" and "FULL".
7. Replace the radiator and reservoir caps and check to be sure the draincocks are fully closed and not leak- ing.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the coolant fan so that you are not injured by a rotating fanblade. As the engine coolant tem- perature decreases, the fan will au- tomatically shut off. This is a nor-mal condition. G070A03Y-AAT The replacement of air cleaner filter is
performed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be lifted off, the old filter removed and the new filter put in its place.
Genuine Hyundai replacement parts
are recommended. HHP5013
