Lower the car to the ground by moving the jack
handle up and down. Then position the wheel brace as shown in the drawing and tighten thewheel nuts. Be sure the socket is seated com-pletely over the nut. Do not stand on the wrenchor use an extension pipe over the wrenchhandle.
Go around the wheel tightening every other nut
until they are all tight. Then double-check eachnut for tightness. After changing wheels, have atechnician tighten the wheel nuts to their propertorque as soon as possible.
Wheel nut tightening torque: Steel wheel & aluminium alloy wheel:90-110 N.m (65-80 lb.ft) D060J02O-EAT
AFTER CHANGING WHEELS
If you have a tyre gauge, remove the valve cap
and check the air pressure. If the pressure is lower than recommended, drive slowly to thenearest service station and inflate to the correctpressure. If it is too high, adjust it until it iscorrect. Always reinstall the valve cap afterchecking or adjusting tyre pressure. If the capis not replaced, air may leak from the tyre. If youlose a valve cap, buy another and install it assoon as possible.
After you have changed wheels, always secure
the flat tyre in its place and return the jack andtools to their proper storage locations. D080A02A-EAT
IF YOUR CAR MUST BE TOWED

F060B01A-AAT
o Drive belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil and replace ifnecessary. Drive belts should be checkedperiodically for proper tension and adjusted asnecessary. F060C01A-AAT
o Fuel filter A clogged filter can limit the speed at which the vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replace-ment more frequently. After installing a new filter, run the engine for several minutes, and check for leaks at theconnections. Fuel filters should be installed bytrained technicians.
F060M01A-AAT o Engine oil and filterThe engine oil and filter should be changed at the intervals specified in the maintenanceschedule. If the car is being driven in severeconditions, more frequent oil and filter changesare required.
F060D01TB-AAT
o Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and connec-tions for leakage and damage. Have a trainedtechnician replace any damaged or leakingparts immediately.
WARNING (Diesel only): Never work on injection system with en-gine running or within 30 seconds aftershutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if ittouch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields. F060E01A-AAT
o Timing beltInspect all parts related to the timing belt for damage and deformation. Replace any dam-aged parts immediately. F060G01A-EAT
o Vapour hose and fuel filler cap The vapour hose and fuel filler cap should be inspected at those intervals specified in themaintenance schedule. Make sure that a newvapour hose or fuel filler cap is correctlyreplaced.
F060F01A-AAT
o Vacuum, crankcase
ventilation hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abrasions,and excessive swelling indicate deterioration.Particular attention should be paid to examinethose hose surfaces nearest to high heatsources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving componentwhich might cause heat damage or mechani-cal wear. Inspect all hose connections, suchas clamps and couplings, to make sure theyare secure, and that no leaks are present.Hoses should be replaced immediately if thereis any evidence of deterioration or damage.

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. SG050A1-E
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.

AUTOMATIC TRANSMISSION LUBRI- CANT Transmission lubricant should be changed at
those intervals specified in the vehicle mainte- nance schedule in Section 5.
NOTE: Basically automatic transmission fluid is red
color. As driving distance increases, the fluid color turns darkish red gradually. It isnormal condition and you should not usefluid color as a criterion for replacing thetransmission fluid.
You must replace the automatic transmis-
sion fluid in accordance with intervals speci-fied in the vehicle maintenances schedule insection 5. Recommended Lubricant
Use only MOBIL DEXRON- II. Damage caused
by a nonspecified fluid is not covered by your new vehicle limited warranty. Transmission Fluid Capacity
The fluid capacity of the automatic transmission
is 10.5 litres (Petrol)/ 11.8 litres (Diesel). CAUTION: The transmission fluid level should be
checked when the engine is at normal oper- ating temperature. This means that the en-gine, radiator, exhaust system etc., are veryhot so you should exercise great care not toburn yourself during this procedure. To Check the Transmission Fluid Level
Park the car on level ground with the parking
brake engaged. When the transmission fluid level is checked, the transmission fluid shouldbe at normal operating temperature and theengine idling.
Whilst the engine is idling, apply the brakes and
move the gear selector level from "P" to each ofits other positions — "R", "N", "D", "2", "L" —and then return to "N" or "P". With the enginestill idling:
1. Open the bonnet, being careful to keep hands and clothing clear of any moving parts.
up, add oil slowly until it reaches the properlevel. Do not overfill.
3. Replace the bolt and washer, screw it in with your fingers and then tighten securely withthe wrench.

3. If the transmission fluid level is low, use a
funnel to add transmission fluid through the dipstick tube until the level reaches the "HOT"range. Do not overfill.
WARNING: The electric engine cooling fan automatical-
ly switches on and off according to engine temperature. Be careful to keep away fromthe fan during this check as it may switch onat any time.
WARNING (Diesel only): Never work on injection system with engine
running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject tohigh pressure even after the engine stopped.The fuel jet produced by fuel leaks maycause serious injury, if it touch the body.People using pacemakers should not move
G110D03Y
Fluid level should be within "HOT" range
than 30cm closer to the ECU or wiring har- ness within the engine room whilst engineis running, since the high currents in theCommon Rail system produce considerablemagnetic fields.
NOTE: Only lint free cloth should be used for wip-
ing the dipstick. The presence of lint within the transmission may cause problems withthe normal function of the transmission.

BRAKE SYSTEM CHECKING CAUTION: Correct operation of the braking system is essential to the safe operation of the vehicleand therefore, any maintenance operationsother than those listed below should beentrusted to a Hyundai dealer. SG120C2-E
Brake Fluid Recommendations Only brake fluid conforming to DOT 3 or DOT 4 specifications or higher may be used in thebraking system. Care should be taken to ob-serve the instructions and precautions printedupon the container. SG120D1-E
Brake Fluid Level
The fluid level in the brake fluid reservoir shouldbe checked periodically. The level should bebetween the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or belowthe "MIN" mark, fluid should be added havingcarefully cleaned the area surrounding the res-ervoir cap to ensure that dirt is not allowed toenter the system. It should be borne in mindthat the brake fluid level will decrease slightlyas the friction linings of the pads and shoesbecome worn and that this is a normal condi-tion. WARNING: Brake fluid is hygroscopic and should never be stored in an unsealed container. Thepresence of water in the braking system willcause vapour locks and increase the possi-bility of brake fade along with promoting

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.
