MAINTENANCE AND SERVICING REQUIREMENTS To ensure the continued reliability and safety
of the vehicle, certain routine maintenance operations are required at specific mileage ortime intervals.
It is the responsibility of the vehicle owner to
ensure that the maintenance schedules shownin both this Owners Manual and the Warrantyand Service Passport are adhered to.
The new vehicle warranty may be invalidated
if the routine maintenance operations are notperformed in line with the recommendationsoutlined and the safety and durability of thevehicle adversely affected.
It is recommended that all maintenance op-
erations with the exception of the daily oper-ating checks are entrusted to a Hyundaiauthorised repairer to ensure that the latestrepair and maintenance procedures andspecialised servicing tools are employed. In addition, the use of genuine Hyundai re-
placement parts will ensure that the vehiclesafety and performance will not be compro-mised. NOTE: The inspection and testing of certain elec-
tronic fuel injection/engine management and automatic transmission control sys-tems require specialised electronic equip-ment specifically designed for Hyundaivehicles. The use of general purpose elec-trical test equipment may result in dam-age to the control unit microprocessors.

Specified Scheduled Procedures The Specified scheduled procedures are listed
in the maintenance charts beginning at page 5-2. The operations specified must be per-formed at the time or mileage intervals shownirrespective of whether the mileage intervalhas been reached before the specified timeinterval.
Certain lubricants and components degrade
with both time and mileage (e.g. engine oil andbrake fluid) and therefore it is not permissableto base the maintenance schedule upon mile-age alone. It is strongly recommended thatthe maintenance operations are performed bythe factory-trained or distributor-trained tech-nicians at your Hyundai authorised repairer because of the need for specialised knowl-edge and tooling and to ensure that no pos-sibility of invalidating the manufacturers war-ranty exists.
The maintenance schedules relate to ve-
hicles operated under normal conditions, ve-hicles which are operated under adverseconditions will require more frequent mainte-nance which is described at page 5-5. NOTE:
Service schedules may change depend-
ing on individual country needs. Please ask your local Hyundai authorised re-pairer for a copy of the service schedulethat relates to that country.
SF030B1-E
SERVICE HISTORY It is important that all scheduled maintenanceservices are recorded in the warranty andservice passport to ensure that proof of main-tenance is available when warranty service isrequired.

operating checks indicate that any item of equip- ment related to the safety or roadworthiness ofthe vehicle is not functioning correctly. G030A01FC-EAT
ENGINE OIL
The correct engine oil level is of paramount
importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil levelmust be checked on a daily basis, wheneverthe vehicle is refuelled or before starting along trip, whichever occurs sooner.
In addition, it is imperative that only an ap-
proved grade and specification of oil is used toavoid the possibility of serious engine damageand premature wear. The use of "budget price"oil is a false economy that must be avoided ifthe maximum reliability and useful life is to beobtained from the vehicle. G030B02O-EAT
Recommended Oil

NOTE: SAE 5W-20 (5W-30), ILSAC GF-3 engine
oil is preferred regardless of regional option and engine variation. If SAE 5W-20,ILSAC GF-3 engine oil is not available,secondary recommended engine oil forcorresponding temperature range can beused. In addition, it is imperative that only an ap-
proved grade and specification of oil is usedto avoid the possibility of serious engine dam-age and premature wear. The use of "budgetprice" oil is a false economy that must beavoided if the maximum reliability and usefullife is to be obtained from the vehicle.
The engine oil quality should meet the follow-
ing classification:
API class: CH-4 or ABOVEACEA class: B4 or ABOVE NOTE: SAE 0W-30 oil is for use in very cold
zones. Its use should therefore be re- stricted only to driving in these type ofsub-zero conditions. (Especially, not rec-ommended for sustained high engine loadand high speed operation.)

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 consumesome engine oil in the course of normaldriving. The cause of oil consumption in anormal engine are as follows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when 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 isburned by the high temperature combustiongases 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. More engine oil may be consumed under severe driving conditions such as highspeeds, frequent acceleration and decel-eration, compared to normal driving.
If the indicated oil level is at or below the lower
mark of the dipstick, oil should be added untilthe level is at or below the upper mark. To add oil to the engine, remove the filler cap
by rotating in an counterclockwise directionand pour engine oil into the engine. Beforechecking the level again, allow several min-utes for the oil to drain into the sump. Replacethe oil filler cap rotating it in a clockwisedirection until tight.
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(Petrol Engine)/1.2liter(Diesel Engine) of oil.
WARNING: Be very careful not to touch the radiator
hose when checking the engine oil as it may be hot enough to burn you.

Withdraw the dipstick and wipe it with a clean rag. Replace the dipstick fully and withdrawagain when the oil level may be read from thestick. Normal oil level is indicated when the oilis present between the two marks on thestick. It is not necessary to add oil if the levelis above the lower mark and in any case, oilmust not be added to the degree that the levelexceeds the upper mark. Replace the dip-stick fully after checking the level. WARNING: Be very careful not to touch the radiator hose when checking the engine oil as itmay be hot enough to burn you.

To replace the oil and filter, proceed as fol-
lows:
1. Ensure that the engine is at normal oper- ating 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.
4. When the oil has drained from the sump, replace the drain plug using a new gasket ensuring that the plug is not over tightened.
5. Remove the oil filter by rotating counter- clockwise, using a proprietary oil filter re-moval tool if necessary. Note that the oilfilter will contain approximately 0.5 litres ofoil and this should be collected in a suit-able receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotatingclockwise until the filter contacts the mount-ing and then a further one half turn. Do notover-tighten Tightening torque: 2.3 ~ 2.5 kgf.m
7. Remove the engine oil level dipstick.
8. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure thatno oil leaks exist. Turn off the engine andafter a couple minutes, recheck the oillevel.
CAUTION: Slowly pour the recommended oil by us-
ing a funnel. Do not overfill to prevent engine to damage. WARNING: Prolonged and repeated contact with used
engine oils may result in serious skin disorders including dermatitis and can-cer. Avoid contact with skin as far aspossible and always wash thoroughly afterany contact. Keep used oils out of reachof children. It is illegal to pollute drains,water courses and soil. Use only autho-rized waste collection facilities includingcivic amenity sites and garages for thedisposal of used oil and oil filters.
