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. HXG094JG030D01A-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.

G030A02O-GAT 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.
Engine oil is essential to the perfor-
mance and service of the engine. It issuggested 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 G030B01JM
NOTE:
o For good fuel economy, SAE 5W-20 (5W-30), ILSAC GF-3 en-gine oil is preferred regardlessof 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. Wait 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 bebetween the upper ("FULL") and lower ("LOW") range.

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.
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 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.
