Before checking the oil, warm up the
engine to normal operating tempera- ture and be sure your vehicle is parked on level ground. Turn the engine off.
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 should be between the upper (F) and lower (L) range.
WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you.

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.
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 clock- wise.
The distance between the "F" and "L" marks is equal to about 1 liter(Gasoline Engine)/1.6 liter(Diesel Engine) of oil.

! CAUTION:
Slowly pour the recommended oil into a funnel. Do not overfill not todamage engine.
WARNING:
Be very careful not to touch theradiator hose when adding the en-gine oil as it may be hot enough to 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 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.
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 maybe reclaimation. Do not pour the oil on the ground or put it in with thehousehold trash.
6. Install a new oil filter in accordance
with the instructions on the cartonor on the filter itself. Do not over- tighten.
Oil filter tightening torque: 1.2~1.6kgf.m Be sure that the mounting surfaceon the engine is clean and that the old gasket is removed completely. Lubricate the new gasket on thefilter with clean engine oil before installation.
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. WARNING:
Used motor oil may cause irrita-
tion or cancer of the skin if left incontact with the skin for prolonged periods of time. Wash your hands thoroughly with soap and warmwater as soon as possible after handling used oil.

Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatiblewith 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 antifreeze to exceed the 60% level or go below the 35% level, or damage tothe cooling system may result. For proper concentration when adding or replacing the engine coolant, refer tothe following table. G050C02E

G050C01A-GAT
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 bebetween the "L" and "F" lines on the reservoir when the engine is cold. If the level is below the "L" mark, addengine coolant to bring it up between "L" and "F". If the level is low, inspect for coolant leaks and recheck thefluid level frequently. If the level drops again, visit your Hyundai dealer for an inspection and diagnosis of the rea-son.
