1- 2 FEATURES OF YOUR HYUNDAI
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 developsdriveability problems, the use of 100% unleaded gasoline is recommended. Fuels with unspecified quantities ofalcohol, or alcohols other than ethanol, should not be used. B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood al- cohol) should not be used in yourHyundai. This type of fuel can reduce vehicle performance and damage com- ponents of the fuel system. B010E01A-AAT Gasolines for Cleaner Air To help contribute to cleaner air, Hyundai recommends that you use gasolines treated with detergent addi- tives, which help prevent deposit for-mation in the engine. These gasolines will help the engine run cleaner and enhance performance of the EmissionControl System.
B010A02A-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Oc- tane Rating of 87 (Research Octane Number 91) or higher must be used in Hyundai vehicle. If leaded gasoline isused, it will cause the catalytic con- verter to become ineffective and the emission control system to malfunc-tion. This can also result in increased main- tenance expense. To avoid accidentaluse of leaded fuel, the large nozzle used with leaded gasoline at service stations can not be inserted into fueltank 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 to Hyundai dealer whether leadedgasoline in your vehicle is avail- able or not.
o Octane Rating of leaded gaso- line is same with unleaded one.

! CAUTION:
Your Hyundai's New Vehicle Lim- ited Warranty may not cover dam- age to the fuel system and perfor-mance problems that are caused by the use of methanol or fuels con- taining methanol.

o If your engine stalls, pings, knocks, or is hard to start, haveyour Hyundai dealer inspect and repair the problem as soon as possible.
o Avoid driving with a very low fuel level. Running out of gaso-line may cause the engine to misfire and result in damage tothe catalytic converter.

CATALYTIC CONVERTER
HXGS509
All Hyundai vehicles are equippedwith a monolith type three-way cata-lytic converter to reduce the carbon monoxide, hydrocarbons and nitro- gen oxides contained in the exhaustgas. Exhaust gases passing through the catalytic converter may cause it to operate at a very high temperature.The introduction of large amounts of unburned gasoline into the exhaust may cause the catalytic converter tooverheat and create a fire hazard. This risk may be reduced by observ- ing the following:
Catalytic Converter o Do not touch the catalytic con-
verter or any other part of the exhaust system while the cata-lytic converter is hot. Shut off the engine, wait for at least one hour before touching the cata-lytic converter or any other part of the exhaust system.
o Remember that your Hyundai dealer is your best source of assistance.
o Do not stop your Hyundai over any combustible material suchas grass, paper, leaves or rags.These materials might contact the hot catalytic converter and a fire might result.
