6CHECKING THE ENGINE OIL
G030A02O-GAT
Recommended Oil Engine oil is essential to the perfor-
mance and service of the engine. It is suggested that you check the oil levelat least once a week in normal use and 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 G030B01JMMAINTENANCE PRECAU- TIONS
!
G020D01TG-GAT Improper or incomplete service may
result in problems. This section gives instructions only for the maintenanceitems that are easy to perform.
Several procedures should be done by
an authorized Hyundai dealer.
NOTE: Improper owner maintenance dur-
ing the warranty period may affect warranty coverage. WARNING:
o Performing maintenance work on a vehicle can be dangerous. You can be seriously injured while performing some maintenance procedures. If you lack sufficientknowledge and experience or the proper tools and equipment to do the work, have it done by anauthorized Hyundai dealer.
o Working under the hood with the engine running is dangerous. It becomes even more dangerous when you wear jewelry or looseclothing. These can become en- tangled in moving parts and re- sult in injury. Therefore, if youmust run the engine while work- ing under the hood, make certain that you remove all jewelry (espe-cially rings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose cloth-ing before getting near the en- gine or cooling fans.

To Check the Oil Level
Before checking the oil, warm up the
engine to the normal operating tem- perature 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 thedipstick and withdraw it again. Then note the highest level the oil hasreached on the dipstick. It should be between the upper ("F") and lower ("L") range. HGK5004
NOTE:
o For good fuel economy, SAE 5W- 20 (5W-30), ILSAC GF-3 engine oilis preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 engine oil is not available, secondaryrecommended engine oil for cor- responding temperature rangecan be used. 1.6L/2.0L
2.7L
!WARNING:
Be very careful not to touch the radiator hose when checking the engine oil as it may be hot enoughto burn you.

G030D01A-GAT Adding Oil

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.
2.7L
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 of oil. WARNING:
Be very careful not to touch the
radiator hose when adding the en- gine 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 and driving condition etc. More engine oil may be consumed under severedriving conditions such as high speeds, frequent acceleration and deceleration, compared to normaldriving condition. G050B01A-AAT Recommended Engine Coolant 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 ofantifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system may result. Forproper concentration when adding or replacing the engine coolant, refer to the following table.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the engine is hot. When the engineis hot, the engine coolant is under pressure and may erupt through the opening if the cap is removed. Youcould be seriously burned if you do not observe this precaution. Do not remove the radiator cap until theradiator is cool to the touch.
