To replace the oil and filter, proceed as follows:
1. Ensure that the engine is at normal operat- ing temperature and park the vehicle on level ground with the parking brake securelyapplied 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 plug fromthe sump.
CAUTION: The oil being drained from the engine will be
hot. Care should be exercised to prevent scalding.
4. When the oil has drained from the sump, replace the drain plug using a new washer ensuring that the plug is not over tightened. Tightening torque is: 3.5 ~ 4.5 kgf.m
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 suitablereceptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotating clock-wise until the filter contacts the mountingand then a further one half turn. Do not over-tighten. Tightening torque: Petrol Engine - 1.2 ~ 1.6 kgf.mDiesel Engine - 2.3 ~ 2.5 kgf.m
7. 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 oil level.
WARNING: Prolonged and repeated contact with used engine oils may result in serious skin disor-ders including dermatitis and cancer. Avoidcontact with skin as far as possible andalways wash thoroughly after any contact.Keep used oils out of reach of children. It isillegal to pollute drains, water courses andsoil. Use only authorized waste collectionfacilities including civic amenity sites andgarages for the disposal of used oil and oilfilters. If in doubt, contact the local authorityfor disposal instructions.

ENGINE COOLANT CHECKING AND REPLACING
WARNING: Do not remove the radiator cap when the engine is hot, since the system is pressur-ized and coolant may be ejected from theradiator resulting in scalding. SG050B1-E
Coolant recommendations Only ethylene glycol based coolant with a cor- rosion inhibitor suited to aluminium alloy enginecomponents should be used in the coolingsystem. No further additives or inhibitors shouldbe used. The coolant specific gravity should bechecked as prescribed in the maintenanceschedule to ensure adequate frost and corro-sion protection. In addition, the engine coolantmust be replaced at the specified interval sincethe corrosion inhibitor properties deteriorate withtime. It is important to note that whilst an increase in the concentration of anti freeze gives an in-crease in the level of frost protection, a solutionwhich is in excess of 65% anti freeze will resultin reduced frost protection and engine over-heating. Therefore the recommended concen-tration of 50% should not be exceeded forgeneral use.The use of methanol based anti freeze com-pounds may result in engine overheating andwill invalidate the vehicle warranty.

OWNER MAINTENANCE 6-7
NOTE: It is imperative that vehicles fitted with an
air conditioning system have a coolant con- centration of the recommended strength atall times. The use of the air conditioningsystem when the cooling system is filledwith water only will result in the heatermatrix freezing and subsequently bursting.
SG050C1-E
Coolant Level
The engine coolant level may be observed
through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant ofthe correct concentration until the level is be-tween the "LOW" and "FULL" marks. If the levelfalls below the "LOW" mark on a regular basisdespite being topped up, consult a Hyundaidealer. HPG050D1-E
To Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-ule in Section 5.
NOTE: Care should be taken to ensure that coolant
is not allowed to spill onto the paintwork since the finish may become damaged. Ifcoolant spillage occurs, the affected areashould be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure that the parking brake is firmly applied, and the engine allowed to cool. Do not attempt this operation whilst the engine is hot since burning or scalding mayresult.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap. NOTE: Petrol Engine Only Before adding the coolant to the radiator,
unscrew the flange bolt for fitting water outlet to escape the excess pressure. And ifthe coolant overflows from the hole whileadding the coolant, screw the bolt and con-tinue to add the coolant.
3. With the heater temperature control set to the "HOT" position, remove the radiator cap and open the radiator drain tap.

4. When the engine coolant has drained com- pletely, close the drain tap ensuring that this is not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour this intothe radiator. 6. Start the engine with the radiator cap still
removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. G060A02L-AAT SPARK PLUGS (For Petrol Engine)

WINDSCREEN WASHER RESERVOIR
REPLENISHMENT The level of windscreen washer fluid available
should be checked on a daily basis. The level of fluid will be visible through the side of thereservoir. When the fluid is to be replenished,only a proprietary screen wash additive shouldbe used and in the concentration recommendedby the manufacturer. The windscreen washerreservoir has a total capacity of 4.5 litres.
CAUTION: Engine coolant anti freeze must not be used
in the windscreen washer system since dam- age to the paintwork may result.
Undiluted windscreen washer additive must
not be allowed to come into contact with thepaintwork. If spillage occurs, flush the af-fected area immediately with water. Do notoperate the windscreen washer for more than 15 seconds continuously or when thereservoir is empty since damage to thewasher pump will result.

EMISSION CONTROL SYSTEMS
7-2
Purge Control Solenoid Valve
The purge control solenoid valve is controlled
by the ECU; when the engine coolant tempera- ture is low, and during idling, it closes, so thatevaporated fuel is not taken into the surge tank.After engine warm-up, during ordinary driving, itopens to introduce evaporated fuel to the surgetank. misfire and result in excessive loading of thecatalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags.
o Do not touch the catalytic converter or any other part of the exhaust system while theengine is running.
o Remember that your Hyundai dealer is your best source of assistance.

3. EXHAUST EMISSION CONTROL
SYSTEM
EGR system ; For a Petrol Engine This system helps control oxides of nitrogen byrecirculating a portion of the exhaust gases intothe intake manifold, thereby reducing cylindercombustion temperatures. YH040A2-E
CATALYTIC CONVERTER
; For a Petrol Engine The catalytic converter is part of the exhaust emission control system. Its purpose is to re-move certain engine emission products fromthe engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system. YH040B1-E
About the Catalytic Converter ; For a Petrol Engine
Exhaust gases passing through the catalytic converter cause it to operate at very high tem-peratures. As a result, the introduction of largeamounts of unburned petrol may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use only unleaded fuel.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can re- sult from improper operation of the electri-cal, ignition or M.P.I. system.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If you run out of petrol, it could cause the engine to H020D01S-GAT CATALYTIC CONVERTER ; For a Diesel Engine All Hyundai vehicles are equipped with oxida- tion type catalytic converter to reduce the car-bon monoxide, hydrocarbons and particulatecontained in the exhaust gas. H020C01HP-EAT EGR SYSTEM ; For a Diesel Engine This system helps control oxides of nitrogen by recirculating a part of the exhaust gas into theengine, there by reducing cylinder combustiontemperature. The EGR system helps reduce Nox (Oxides of Nitrogen) emission gasses.
