CHANGING THE OIL AND FIL- TER tion 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 coolant temperaturegauge moves above the lowest mark. Turn the engine off and place the 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 the proper size. Be sure that a drainpan is in position to catch the oil as it drains out, then remove the drain plug.

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 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.
!
The distance between the "F" and "L" marks is equal to about 1 liter of oil.
WARNING:
Be very careful when draining the engine oil as it may be hot enough to burn you!
o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm anddriving 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.
The engine oil and filter should be
changed at those intervals specifiedin the maintenance schedule in Sec-

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 ~4.0 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. Remove the engine oil level dip-
stick.
8. Refill the crankcase with the rec- ommended engine oil. Refer tothe specification in chapter 9 forengine oil capacity.

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 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 ra- diator cap until the radiator is cool to the touch.

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.
CAUTION
Slowly pour the recommended oil
using by a tunnel. Do not overfill not to damage engine.
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.
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 in with the house-hold trash.

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.

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 "L" and "F" lines on thereservoir when the engine is cool. If the level is below the "L" mark, add G050C01L

Recommended Engine Coolant
G050B01L engine 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.
