7CHECKING THE ENGINE OIL
If you notice anything that does not
operate correctly or appear to be func- tioning correctly, inspect it carefully and seek assistance from your Hyundai dealer if service is needed.
Adequate care of your vehicle at regu-
lar intervals serves to preserve thevalue and appearance as long aspossible.
Some maintenance items can be car-
ried out by the owner (Consumer Information), while other should be done only by an authorized dealer(Periodic Inspection and Mainte- nance). This section describes only those items which can be carried outby the owner. In the event a malfunc- tion or other problem is discovered, have it corrected by an authorizedHYUNDAI dealer. This section con- tains information on inspection main- tenance procedures that you can doyourself, if you so desire. Follow the instructions and cautions for each of the various procedures. When checking or servicing the in-side of the engine compartment, besure the engine is stopped and has had a chance to cool down. If it is necessary to do work in the enginecompartment with the engine running, be especially careful that your cloth- ing, hair, etc., becomes not caught bythe fan, V-belts, or other moving parts.

NOTE: For diesel-powered vehicle SAE 0W-30 oil should be used only inareas where extremely cold tem- peratures of 10°C (50°F) or below are experienced. For diesel-powered vehicle, if the atmospheric temperatures are 0°C (32°F) or below, SAE 30 oil mustnot be used. This oil should be used only in areas where the at- mospheric temperatures are0°C(32°F) or above. (2) The engine oil quality should meet
the following API classification: 2.6 N/A : CF-4 or ABOVE 2.5 4D56 TCI : CF-4 or ABOVE 2.5 CRDi TCI : CF-4 or ABOVE
(2) The engine oil quality should meet the following ACEA classification: 2.6 N/A : B2 or B3 2.5 4D56 TCI : B2 or B3 2.5 CRDi TCI : B4 or ABOVE
Recommended Oil Gasoline Engine Select engine oil of the proper SAE viscosity number according to the at- mospheric temperature.Recommended viscosity is given inthe following illustration. NOTE: SAE 5W-20 is not recommended for sustained high speed vehicle operation. The engine oil quality should meet the following API classification.

10CHECKING THE ENGINE COOLANT
G350A01A-GAT 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. I080A02P-GAT
!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 erupt through the opening if the cap isremoved. You could be seriously burned if you do not observe this precaution. Do not remove theradiator cap until the radiator is cool to the touch.
