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.
B010A02O-GAT Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or higher must be used in Hyundaivehicle. If leaded gasoline is used, it will cause the catalytic converter to become ineffective and the emissioncontrol system to malfunction. This can also result in increased mainte- nance 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 touse leaded gasoline, ask to Hyundai 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 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:
Do not let any gasoline or water enter the 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.

Charging System Warning Light
The charging system warning light should come on when the ignition isturned on, then go out when the engine is running. If the light stays on while the engine is running, there is a malfunc-tion in the electrical charging system. If the light comes on while you are driv- ing, stop, turn off the engine and checkunder the hood. First, make certain the generator drive belt is in place. If it is, check the tension of the belt.And then, have the system checked by your Hyundai dealer.
CAUTION:
If the drive belt (generator belt) is loosen, broken, or mission whilethe vehicle is driving, there may be a serious malfunction, engine could overheat because this belt alsodrives the water pump.

The catalytic converter is part of the
exhaust emission control system. Its purpose is to remove certain engine emission products from the engine'sexhaust. It looks something like a muffler and is located underneath the car in the exhaust system.

About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amountsof unburned gasoline may cause it to overheat and create a fire hazard. This can be avoided by observing thefollowing:
o Use unleaded fuel only.
o Maintain your engine in good con- dition. Extremely high convertertemperatures can result from im-proper operation of the electrical, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car toyour Hyundai dealer as soon as possible and have the difficultycorrected.
o Avoid driving with a very low fuel
level. If your run out of gasoline, itcould cause the engine to misfire and result in excessive loading 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 the catalytic con- verter to overload.
o Take care not to stop your Hyundai over any combustible material suchas grass, paper, leaves or rags. As these materials could come in con-tact with the catalytic converter and could cause a fire.
o Do not touch the catalytic con- verter or any other part of the ex-haust system while the engine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai
dealer is your best source of assis-tance.
