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 drive ability problems, the use of 100% un- leaded gasoline is recommended. Fu-els with unspecified quantities of alco- hol, 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 main-tenance expense. To avoid accidental use of leaded fuel, the large nozzle used with leaded gasoline at servicestations can not be inserted into fuel tank opening of your Hyundai.
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 gasoline
is same with unleaded one.
Use Diesel Diesel fuel of 52 to 54 cetane is the correct rating to use in your Hyundai. If two types of diesel fuel are available, use summer or winter fuel properlyaccording to the 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, the circuits must be com- pletely purged to permit restarting. CAUTION:
o Do not let any gasoline or water enter the tank. This would makeit 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.

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEMS
H010A01A-GAT
(If Installed)
Your Hyundai is equipped with an
emission control system to meet all requirements of the Emission prohibi- tion rules of your province.
There are three emission control sys-
tems which are as follows.
(1) Crankcase emission control sys- tem (For a Gasoline Engine)
(2) Evaporative emission control sys- tem (For a Gasoline Engine)
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is recommended that you have your carinspected and maintained by an au- thorized Hyundai dealer in accordance with the maintenance schedule in thismanual. H010B01A-AAT
1. Crankcase Emission Control
System ; For a Gasoline Engine
The positive crankcase ventilation
system is employed to prevent air pollution caused by blow-by gasesbeing emitted from the crankcase. This system supplies fresh filtered air to the crankcase through the air in-take hose. Inside the crankcase, which the fresh air mixes with blow-by gases, which then pass through the PCVvalve into the induction system.
H010C02Y-GAT
2. Evaporative Emission
Control System ; For a Gasoline Engine
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo- sphere. Canister
While the engine is inoperative, fuel
vapors generated inside the fuel tankare absorbed and stored in the canis- ter. When the engine is running, thefuel vapors absorbed in the canister are drawn into the induction system through the purge control solenoidvalve. Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECM; when the en- gine coolant temperature is low, and during idling, it closes, so that evapo- rated fuel is not taken into the surgetank. After engine warm-up, during ordinary driving, it opens so as to introduce evaporated fuel to the surgetank. H010D01A-AAT
3. Exhaust Emission Control
System
The Exhaust Emission Control Sys- tem is a highly effective system whichcontrols exhaust emissions while maintaining good vehicle performance.

DH010B1-E
1. Crankcase Emission Control System ; For a Petrol Engine
The positive crankcase ventilation
system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase.
This system supplies fresh air to the
crankcase through the air cleaner.Inside the crankcase, the fresh airmixes with blow-by gases, then passes through the PCV valve into the intake system.
ZH010C1-E
2. Evaporative Emission Control System ; For a Petrol Engine
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo-sphere. Canister
Whilst the engine is inoperative, fuel
vapors generated inside the fuel tankare absorbed and stored in the canis-ter. When the engine is running, the fuel vapors absorbed in the canister are drawn into the induction systemthrough the purge control solenoid valve. Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECU; when the en- gine coolant temperature is low, and during idling, it closes, so that evapo- rated fuel is not taken into the surgetank. After engine warm-up, during ordinary driving, it opens to introduce evaporated fuel to the surge tank.
SH010D1-E
3. Exhaust Emission Control System
The exhaust emission control system
is a highly effective system which controls exhaust emission while main- taining good vehicle performance.
Catalytic Converter H020A01HP-D
CATALYTIC CONVERTER ; For a Petrol Engine
YH040A2-E The catalytic converter is part of the exhaust emission control system. Its purpose is to remove certain engineemission products from the engine's exhaust. It looks something like a muffler and is located underneath thecar in the exhaust system.
