SCHEDULED MAINTENANCE In order to ensure the continued safety, reliability and longevity of the
vehicle, the following maintenance service operations should be per- formed at the time or mileage intervals specified.
It is recommended that all routine maintenance services are entrusted to a Hyundai dealer to ensure that the manufacturers recommendedprocedures are employed and that only genuine Hyundai replacementparts are used. Incorrect maintenance techniques or the use of nongenuine replacement parts may invalidate the vehicle warranty.

6-6 the level again, allow several minutes for the oil to drain into the sump. Replace the oil fillercap rotating it in a clockwise direction untiltight. The quantity of oil required to raise the level from the minimum to maximum level is approx-imately 1 litre. The distance between the "F" and "L" marks is equal to about 1 liter(Gasoline Engine)/1.2liter(Diesel Engine) of oil.
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 severe driving conditions such as highspeeds and frequent acceleration and de-celeration than normal driving condition.
ZG030E1-A
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. A thin film of oil is left on the cylinder wallwhen a piston moves downwards in thecylinder. 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. SG040A1-E
ENGINE OIL AND FILTER
REPLACEMENT
SSA6040A
Oil filler cap
Drain plug
Oil filter The engine oil and filter must be changed at
the time or mileage interval specified in the maintenance schedule. If the vehicle is oper-ated under severe or adverse conditions, theoil and filter must be replaced more frequently.
To replace the oil and filter, proceed as fol-
lows:
1. Ensure that the engine is at normal operat- ing temperature and park the vehicle on level ground with the parking brake se-curely applied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.
3. Prepare a suitable receptacle to collect the displaced oil and remove the drain plugfrom the sump.
CAUTION: The oil being drained from the engine will
be hot. Care should be exercised to pre- vent scalding.

6-14 SG130A1-C CHECKING THE CLUTCH FLUID To Check the Clutch Fluid
SG130B2-E
Adding Fluid
Recommended brake fluid conforming to DOT 3 or DOT 4 should be used. The reservoir capmust be fully tightened to avoid contaminationfrom foreign matter or moisture. CAUTION: Brake fluid is hygroscopic and should never be stored in an unsealed container.Do not allow petroleum base fluid tocontaminate the brake fluid since damageto the rubber seals of the system mayresult. WARNING: Brake fluid will cause rapid and serious damage to paintwork. If accidental spillageoccurs, the affected area must be rinsedwith water immediately. Do not allow brakefluid to come into contact with the eyes or tobe ingested and ensure that fluid is safelystored away form the reach of children.
HFC5005
Gasoline engine
The clutch fluid level in the master cylinder should be checked when performing other un-der bonnet checks. The system should bechecked for leakage at the same time.
G120D02FC
Diesel engine
WARNING: Brake fluid is hygroscopic and should never be stored in an unsealed container.The presence of water in the brakingsystem will cause vapour locks and in-crease the possibility of brake fade alongwith promoting corrosion within the brak-ing system. The brake fluid must bechanged at the specified time or mileageinterval to ensure continued safe opera-tion of the system. Brake fluid will causerapid and serious damage to paintwork. Ifaccidental spillage occurs, the affectedarea must be rinsed with water immedi-ately. Do not allow brake fluid to comeinto contact with the eyes or to be in-gested and ensure that fluid is safelystored away form the reach of children.
G120D02FC
Diesel engine
Ensure that the clutch fluid level is always between the "MAX" and "MIN" level markingson the fluid reservoir. Fill as required. Fluidloss indicates a leak in the clutch systemwhich should be inspected and repaired im-mediately.
