To Check the Oil Level G030D01A-GAT
Adding Oil
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-draw it again. Then note the highest level the oilhas reached on the dipstick. It should be be-tween the upper ("FULL") and lower ("LOW")range. 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 clockwise.
The distance between the "F" and "L" marks is
equal to about 1 liter of oil.HGK211

See the lubrication chart on the page 9-3. NOTE:
o The use of a 5W-20 multi grade oil is not recommended for sustained high speed use.
o When replacing or adding the oil, below SAE 10W-30 is recommended. Using a high viscosity oil of SAE 15W-40 and over makes malfunction of CVVTengine when the engine is cool.

CHANGING THE OIL AND FILTER
The engine oil and filter should be changed at those intervals specified in the maintenanceschedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges 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 itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
G040A01GK 3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with a wrench of the proper size. Be surethat a drain pan is in position to catch the oilas it drains out, then remove the drain plug.
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 washer and retighten by turning it clockwise. Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L) 4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of the proper size. A certain amount of oil willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filteritself. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.Be sure that the mounting surface on the engine is clean and that the old gasket isremoved completely. Lubricate the new gas-ket on the filter with clean engine oil beforeinstallation.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume
some engine oil while normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders.
o A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generatedduring engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Moreengine oil may be consumed under severedriving conditions such as high speeds, fre-quent acceleration and deceleration, com-pared to normal driving condition. V6

CHECKING AND CHANGING THE EN- GINE 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 mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant shouldbe compatible with aluminum engine parts.Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of anti-freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing the engine coolant, refer to thefollowing table.
HGK187
35% 40%50%60%
G050C01A-AAT
To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cool.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil.
