B010A01O-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or highermust be used in Hyundai vehicle. If leadedgasoline is used, it will cause the catalyticconverter to become ineffective and the emis-sion control system to malfunction. This canalso result in increased maintenance expense.To avoid accidental use of leaded fuel, the largenozzle used with leaded gasoline at servicestations can not be inserted into fuel tankopening of Hyundai vehicle. NOTE:
o For some countries, Hyundai vehicles
are designed to use leaded gasoline.When you are going to use leaded gaso-line, ask to Hyundai dealer whether leadedgasoline in your vehicle is available ornot.
o Octane Rating of leaded gasoline is same with unleaded one.
Use Diesel Diesel fuel of 52 to 54 cetane is used in Hyundai vehicle. If two types of diesel fuel are available,
use summer or winter fuel properly according tothe following temperature conditions.
o Above -5°C (23°F) ... Summer type diesel fuel.
o Below -5°C (23°F) ... Winter type diesel fuel.Watch the fuel level in the tank very carefully : If the engine stops through fuel failure, thecircuits must be completely purged to permitrestarting. CAUTION:
o Do not let any gasoline or water enter the tank. This would make it necessary todrain it out and to bleed the lines to avoidjamming the injection pump and damag-ing the engine.
o In winter, in order to cut down incidents due to freezing, paraffin oil may be addedto the fuel if the temperature drops tobelow -10°C. Never use more than 20%paraffin oil. B010B01A-AAT What About Gasohol?Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be usedin your Hyundai. However, if your engine devel-ops driveability problems, the use of 100%unleaded gasoline is recommended. Fuels withunspecified quantities of alcohol, or alcoholsother than ethanol, should not be used. B010E01A-AAT Gasolines for Cleaner Air To help contribute to cleaner air, Hyundai rec- ommends that you use gasolines treated withdetergent additives, which help prevent depositformation in the engine. These gasolines willhelp the engine run cleaner and enhance per-formance of the Emission Control System.
B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood alcohol) should not be used in your Hyundai. This typeof fuel can reduce vehicle performance anddamage components of the fuel system. CAUTION: Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuelsystem and performance problems that are
caused by the use of methanol or fuelscontaining methanol.

7. Pull out the oil filter upper cap with element from the lower case. Using a clean cloth, remove any dirt or oil accumulated around the lower case.
8. Install a new copper washer of the oil filter drain plug by the side of lower case andretighten by turning it clockwise.
Tightening torque : 0.8 ~ 1.0 kgf.m
9. After mounting a new oil filter element and new O-ring to upper cap, install the upper cap to lower case and retighten by turning itclockwise. Do not over-tighten.
Tightening torque : 2.3 ~ 2.5 kgf.m
10. Refill the crankcase with the recommended engine oil. Refer to the specification in chap- ter 9 for engine oil capacity.
11. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
12. Shut off the engine and recheck the oil level.
NOTE: It is recommended that the engine oil and
filter should be changed by an authorized Hyundai dealer. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it into the household trash. WARNING: Used motor oil may cause irritation or
cancer
of the skin if left in contact with the skin for prolonged periods of time. Wash your handsthoroughly with soap and warm water assoon as possible after handling used oil.

REPLACING HEADLIGHT BULBS Before attempting to replace a headlight bulb, be sure the switch is turned to the "OFF"position. The next paragraph shows how to reach the headlight bulbs so they may be changed. Besure to replace the burned-out bulb with one ofthe same number and wattage rating. CAUTION: Keep the lamps out of contact with petro- leum products, such as oil, gasoline, etc.
G240A01A-AAT
POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular intervals. The power steering hoses should bereplaced if there is severe surface cracking,scuffing or worn spots. Deterioration of thehose could cause premature failure. NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. It is due to a power steeringfluid characteristic in extremely cold condi-tions.
Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power
steering oil reservoir is empty. G300A01B-GAT
REMOVAL OF WATER FROM THE FUEL FILTER (DIESEL ENGINE)
If the fuel filter warning light illuminates during driving, it indicates that water has accumulatedin the fuel filter. If this occurs, remove the wateras described below. 1. Loosen the drain plug at the bottom of the
fuel filter.
2. Tighten the drain plug when water no longer comes out.
3. Check to be sure that the warning lamp illuminates when the ignition key is turned to"ON", and that it goes off when the engine isstarted. If in doubt, consult your nearest authorized HYUNDAI dealer.
WARNING: Be sure to carefully wipe away any waterdrained out in this manner, because the fuelmixed in the water might be ignited andresult in a fire.

About the Catalytic Converter
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 gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
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 your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic 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. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

EQUIPMENT
B010A02O-EAT FUEL RECOMMENDATIONS THIS VEHICLE MUST ONLY BE OPERATED WITH UNLEADED FUEL. SERIOUS DAMAGE WILL RESULT FROM THE USE OF LEADED FUEL.
UNLEADED FUEL ONLY
Unleaded fuel with a Research Octane Num- ber (RON) of 91 or higher must be used in thisvehicle. To prevent accidental charging of the fuel tank with leaded fuel, a small diameter fillerneck along with a restrictor flap are fitted toensure that only unleaded fuel pump nozzlesmay enter the filler neck. However, care mustbe exercised when charging the vehicle tank SB010E1-A GASOLINES FOR CLEANER AIR To help contribute to cleaner air, Hyundai recommends that you use gasolines treatedwith detergent additives, which help to pre-vent deposit formation in the engine. Thesegasolines will help the engines run cleanerand the Emission Control System performance.
CAUTION: Do not let any gasoline or water enter the tank. This would make it necessary todrain it out and to bleed the lines to avoidjamming the injection pump and damagingthe engine. Overseas Operation: When the vehicle is to be operated overseas, the vehicle operator should establish that asuitable fuel for satisfactory operation of thevehicle is available.

CAUTION:
Personal injury and damage to the vehicle
may occur if jump starting is not per- formed correctly. If any doubt exists as tohow this operation should be performed,seek assistance from qualified personnel. WARNING:
Motor vehicle batteries contain sulphuric
acid and emit hydrogen gas. Protective clothing should be worn and care exer-cised to prevent the acid from coming intocontact with skin or clothing and the ve-hicle. Naked lights should not be permittedin the vicinity of the battery. Care shouldbe exercised to prevent sparks occurringduring connection. If acid accidentallycomes into contact with skin or eyes, theaffected area should immediately be flushed ponents such as the Fuel Injection system
computer and the Automatic Transaxlecomputer. The battery must never be dis-connected whilst the engine is running. SD040A2-E IF THE ENGINE OVERHEATS If the temperature gauge indicates overheat- ing:
1. Pull off the road and stop as soon as it is
safe to do so.
2. Place the gear selector lever in "P" (auto- matic), or neutral (manual transaxle) and set the parking brake. If the air condition-ing is on, turn it off.
3. If coolant is running out under the car or steam is coming out from under the bonnetstop the engine. Do not open the bonnetuntil the coolant has stopped running orthe steaming has stopped. If there is novisible loss of coolant and no steam, leavethe engine running and check to be surethe engine cooling fan is operating. If the fan is not running, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing, check to see that it is tight. If the drive belt seems to besatisfactory, check for coolant leaking fromthe radiator, hoses or under the car. (If theair conditioning had been in use, it isnormal for cold water to be draining fromit).
SD030A1-E JUMP STARTING
with copious amounts of water and medi- cal assistance sought.
1. Ensure that the booster battery is 12 volt type. If the booster battery is installed inanother vehicle, ensure that the two vehi-cles are not touching.
2. Turn off all unnecessary electrical equip- ment in both vehicles.
3. Ensure that the engine of the vehicle pro- viding the jump start is running prior toconnection of the jump cables.
4. Connect the red jump cable to the positive (+) terminal of the booster battery and theother end to the positive (+) terminal of thedischarged battery.
5. Attach the black jump cable to the nega- tive (-) terminal of the booster battery, andthe other end to a ground point within theengine compartment of the vehicle withthe flat battery. Do not connect to thenegative battery terminal of the flat batterysince sparks may be generated with thesubsequent risk of explosion.
6. Raise the booster vehicle engine speed to 2,000 r.p.m. and start the engine of thevehicle with the flat battery.

ELECTRIC COOLING FANS
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fan blade.As the engine coolant temperature decreas-es, the fan will automatically shut off. Thisis a normal condition. The engine cooling fan should operate before the temperature gauge reaches the upper por-tion of the scale and the condenser fan shouldoperate whenever the air conditioning is in use. The power steering fluid level should bechecked daily. To check the power steering fluid level, be sure the ignition is "OFF", then check to makecertain that the power steering fluid level isbetween the "MAX" and "MIN" level markingson the fluid reservoir. NOTE: Grinding noise from power steering pump may be heard immediately after the engineis started in extremely cold condition(below -4°F). If the noise stops during warmup, there is no abnormal function in thesystem. This is due to a power steeringfluid characteristic in extremely cold con-ditions.

EMISSION CONTROL SYSTEM
7-2
It is of the utmost importance that the following information is read and understood by thevehicle operator in order to prevent operationalproblems arising from damage to the catalyst.Damage to the catalyst will result if contamina-tion occurs through the use of leaded fuel.Whilst the vehicle is fitted with a reduced diam-eter filler neck to prevent charging of the fueltank with a leaded fuel pump nozzle, it ispossible that the use of funnels or jerry cans willpermit leaded fuel to be introduced into the fueltank.The catalyst is intolerant of unburnt fuel andtherefore if an engine misfire condition exists,damage to the catalyst will occur. It is impera-tive that if a misfire condition develops, thevehicle is immediately presented to a Hyundaidealer for rectification. Similarly, the practice ofcertain ignition system diagnosis procedureswhich involve inducing a misfire (cylinder powerbalance tests for example) may result in cata-lyst damage.For these reasons, it is advisable that theexhaust gas emission be tested at each routineservice with a gas analyzer having a Hydrocar-bon measuring facility to ensure continuedreliability of the catalyst.Push or tow starting of the vehicle is to beavoided since unburnt fuel may be enter thecatalyst and result in damage. (Note, it isimpossible to push or tow start a Hyundaimodel equipped with fuel injection since thefuel pump safety interlock will prevent the pumpfrom operating under these conditions).
Operation of the catalyst involves extremelyhigh temperatures being attained within thecatalytic convertor, and although the convertoris fitted with heat shields, it is important that thevehicle is not parked over combustible or vola-tile material which may result in fire.If the above precautions are not adhered to andthe catalyst becomes inoperative, the resultantincrease in core temperature will result in a"melt down" where the catalyst core will meltand subsequently may block the exhaust sys-tem.Due to the fragile nature of the catalyst ele-ment, it is important that damage does notoccur when the vehicle is raised by means of agarage jack. Care must also be exercised toavoid driving over road hazards or debris whichmay cause damage to the catalyst element.
