CONTROLS AND EQUIPMENTHowever, care must be exercised when re- fuelling the vehicle tank from jerry cans or bymeans of a funnel that the fuel being used isunleaded. The use of leaded fuel in this vehicle will result in irreversible pollution of the catalyst ele-ment. Such pollution will prevent correct op-eration of the catalyst and give rise to in-creased operating temperatures leading tothe catalyst element melting and restrictingthe exhaust flow along with an increase inexhaust emission levels. CAUTION: The vehicle warranty will not extend to damage arising from the use of incorrectfuels. DIESEL ENGINES Diesel fuel of 52 to 54 cetane is used in diesel engined Hyundai vehicle. If two types of dieselfuel are available, use summer or winter fuelproperly according to the following tempera-ture conditions.
o Above 23°F (-5°C) ... Summer type diesel fuel.
o Below 23°F (-5°C) ... Winter type diesel fuel. Watch the fuel level in the tank very carefully: If the engine stops through fuel failure, the circuits must be completely purged to permitrestarting.

B010A03O-EAT PETROL ENGINES THIS VEHICLE MUST ONLY BE OPER-ATED WITH UNLEADED FUEL.SERIOUS DAMAGE WILL RESULT FROMTHE 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 fueltank 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. CAUTION: Do not let any petrol or water enter the tank. If this happens, the tank should becompletely drained and the fuel linesshould all be cleaned out. This will stopthe fuel pump from becoming contami-nated.

B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be used in your Hyundai.However, if your engine develops driveability problems, the use of 100% unleaded gasoline is recommended.Fuels with unspecified quantities of alcohol, or alcohols other than ethanol, should not be used.
B010A01O-GAT Use Unleaded Gasoline Unleaded gasoline with a Pump Oc- tane Rating of 87 (Research Octane Number 91) or higher must be used inHyundai vehicle. If leaded gasoline is used, it will cause the catalytic con- verter to become ineffective and theemission control system to malfunc- tion. This can also result in increased maintenance expense. To avoid acci-dental use of leaded fuel, the large nozzle used with leaded gasoline at service stations can not be insertedinto fuel tank opening of Hyundai ve- hicle.
NOTE:
o For some countries, Hyundai
vehicles are designed to use leaded gasoline. When you aregoing to use leaded gasoline, ask to Hyundai dealer whether leaded gasoline in your vehicleis available or not.
o Octane Rating of leaded gaso-
line 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 win- ter fuel properly according to the fol-lowing 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 throughfuel failure, the circuits must be com- pletely purged to permit restarting. CAUTION:
o Do not let any gasoline or water enter the tank. This would make it necessary to drain it out and to bleed the lines to avoid jamming the injection pump and damag-ing the engine.
o In winter, in order to cut down
incidents due to freezing, paraf-fin oil may be added to the fuel if the temperature drops to below - 10°C. Never use more than 20% paraffin oil.
