B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grainalcohol) 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.
B010A03O-GAT Use Unleaded Gasoline For Europe
– For the optimal vehicle
performance, we recommend you to use unleaded gasoline with an octanerating of RON (Research Octane Num- ber) 95 /AKI (Anti Knock Index) 91 or higher.You may use unleaded gasoline with an octane rating of RON 91~94/AKI 87~90 but it may result in slight performancereduction of the vehicle. Except Europe – Unleaded gasoline
with a Pump Octane Rating of 87 (Re- search Octane Number 91) or higher must be used in Hyundai vehicle. If leaded gasoline is used, it will causethe catalytic converter to become inef-fective and the emission control sys- tem to malfunction. This can also result in increased maintenance expense.To avoid accidental use of leaded fuel, the large nozzle used with leaded gaso- line at service stations can not beinserted into fuel tank opening of Hyundai vehicle. NOTE:
o For some countries, Hyundai ve-
hicles are designed to use leaded gasoline. When you are going to use leaded gasoline, ask toHyundai dealer whether leaded gasoline in your vehicle is avail- able 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 dieselfuel are available, use summer or win- ter fuel properly according to the fol- lowing temperature conditions. CAUTION:
Do not let any gasoline or water enterthe tank. This would make it neces-sary to drain it out and to bleed the lines to avoid jamming the injection pump and damaging the engine.

FUEL RECOMMENDATIONS
o Above -5°C (23°F) ... Summer typediesel 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, the circuits must be com-pletely purged to permit restarting.

B010A03O-EAT PETROL ENGINES THIS VEHICLE MUST ONLY BE OP- ERATED WITH UNLEADED FUEL.SERIOUS DAMAGE WILL RESULT FROM THE USE OF LEADED FUEL. Unleaded fuel with a Research Octane Number (RON) of 91 or higher must be used in this vehicle.To prevent accidental charging of the fuel tank with leaded fuel, a small diameter filler neck along with arestrictor flap are fitted to ensure that only unleaded fuel pump nozzles may enter the filler neck. However, care must be exercised whenrefuelling the vehicle tank from jerrycans or by means of a funnel that the fuel being used is unleaded. The use of leaded fuel in this vehicle willresult in irreversible pollution of the catalyst element. Such pollution will prevent correct operation of the cata-lyst and give rise to increased operat- ing temperatures leading to the cata- lyst element melting and restricting theexhaust flow along with an increase in exhaust emission levels.
