6CHECKING THE ENGINE OIL
G030A02O-GAT
Recommended Oil Gasoline Engine 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. The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JMNOTE:
o For good fuel economy, SAE 5W-20 (5W-30), ILSAC GF-3 en-gine oil is preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 en- gine oil is not available, second-ary recommended engine oil forcorresponding temperature range can be used.

To Check the Oil Level
HFC5007
Gasoline engine
Wait about five minutes, then remove
the dipstick, wipe it off, fully reinsert the dipstick and withdraw it again. Then note the highest level the oil has reached on the dipstick. It shouldbe between the upper "F" and lower "L" range.

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 asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder 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 during the 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 severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.
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 clock- wise.
The distance between the "F" and "L"marks is equal to about 1 liter(GasolineEngine)/1.2 liter(Diesel Engine) of oil.

CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfillnot to damage engine.
!
NOTE: Always dispose of used engine oil in an environmentally acceptablemanner. It is suggested that it be placed in a sealed container and taken to a service station for maybereclaimation. Do not pour the oil on the ground or put it in with the household trash.
Be sure that the mounting surfaceon the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean engine oil beforeinstallation.
7. Remove the engine oil level dip- stick.
8. Refill the crankcase with the rec-
ommended engine oil. Refer tothe specification in chapter 9 for engine oil capacity.
!
9. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
10.Shut off the engine and recheck the oil level. 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. G040B04FC-GAT

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.

G050A01A-AAT
WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolant is under pressure and may eruptthrough the opening if the cap is removed. You could be seriously burned if you do not observe thisprecaution. Do not remove the radiator cap until the radiator is cool to the touch.

Use a high quality ethylene-glycol
coolant in a 50/50 mix with water.
10.Start the engine and check to be
sure no oil is leaking from thedrain plug or oil filter.
11.Shut off the engine and recheck
the oil level.
NOTE:
o It is recommended that the en- gine oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally accept-able manner. It is suggested that it be placed in a sealed container and taken to a service station formaybe reclaimation. Do not pour the oil on the ground or put it into the household trash.

The engine coolant should be com- patible with aluminum engine parts.Additional corrosion inhibitors or addi- tives should not be used. The cooling system must be maintained with thecorrect concentration and type of en- gine coolant to prevent freezing and corrosion. Never allow the concentra-tion of antifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system mayresult. For proper concentration when adding or replacing the engine cool- ant, refer to the following table. G050C01A-GAT
To Check the Coolant Level The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between"L" and "F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.
