B010A02A-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or highermust be used in Hyundai vehicle. If leaded gaso-line is used, it will cause the catalytic converter tobecome ineffective and the emission controlsystem to malfunction.This can also result in increased maintenanceexpense. To avoid accidental use of leaded fuel,the large nozzle used with leaded gasoline atservice stations can not be inserted into fuel tankopening of Hyundai vehicle. NOTE:
o For some countries, Hyundai vehicles are
designed to use leaded gasoline. Whenyou are going to use leaded gasoline, askto Hyundai dealer whether leaded gaso-line in your vehicle is available or not.
o Octane Rating of leaded gasoline is same with unleaded one.
B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be usedin your Hyundai. However, if your engine devel-ops driveability problems, the use of 100% un-leaded gasoline is recommended. Fuels withunspecified quantities of alcohol, or alcoholsother than ethanol, should not be used. B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel canreduce vehicle performance and damage com-ponents of the fuel system. CAUTION: Your Hyundai's New Vehicle Limited War-ranty may not cover damage to the fuel sys-tem and performance problems that arecaused by the use of methanol or fuels con-taining methanol. B010E01A-AAT Gasolines for Cleaner AirTo help contribute to cleaner air, Hyundai recom- mends that you use gasolines treated with deter-gent additives, which help prevent deposit for-mation in the engine. These gasolines will helpthe engine run cleaner and enhance performanceof the Emission Control System. B010F01A-AAT Operation in Foreign Countries If you are going to drive your Hyundai in another country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available. B020A01S-GAT BREAKING IN YOUR NEW HYUNDAI During the First 2,000 Km (1,200 Miles) No formal "break-in" procedure is required with your new Hyundai. However, you can contributeto the economical operation and durability of yourHyundai by observing the following recommen-dations during the first 2,000 km (1,200 miles).
o Don't drive faster than 88 km/h (55 mph).
o While driving, keep your engine speed (rpm, or revolutions per minute) between 2,000 rpmand 4,000 rpm.
o Use moderate acceleration. Don't start, de- press the accelerator pedal fully.

H010B01F-GAT
1. Crankcase Emission Control Sys-
tem
The positive crankcase ventilation system is
employed to prevent air pollution caused by H010A01A-GAT
EMISSION CONTROL SYSTEMS (If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the Emission prohibition rules of your province.
There are three emission control systems which
are as follows.
(1) Crankcase emission control system (2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of the
emission control systems, it is recommended that you have your car inspected and main-tained by an authorized Hyundai dealer in ac-cordance with the maintenance schedule in thismanual. H010C01F-GAT
2. Evaporative Emission Control Sys-
tem (If Installed)
The evaporative emission control system is
designed to prevent fuel vapors from escapinginto the atmosphere. Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and stored in the canister. When the engine is
running, the fuel vapors absorbed in the canis-ter are drawn into the induction system throughthe purge control solenoid valve. Purge Control Solenoid Valve
The purge control solenoid valve is controlled
by the ECM; when the engine coolant tempera- ture is low, and during idling, it closes, so that
evaporated fuel is not taken into the engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine. H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sions while maintaining good vehicleperformace.

The catalytic converter is part of the exhaust
emission control system. Its purpose is to re- move certain engine emission products fromthe engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system.
blow-by gases being emitted from the crank-
case. This system supplies fresh air to the
crankcase through the air cleaner. Inside thecrankcase, the fresh air mixes with blow-bygases, then passes through the PCV valve intothe induction system.

About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading 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 thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

1. CRANKCASE EMISSION CONTROL SYSTEM
The positive crankcase ventilation system is employed to prevent air pollution caused byblow-by gases being emitted from the crankcase by introducing fresh air to the crankcase throughthe air cleaner where this mixes with blow-bygases and then passes through the PCV valveinto the intake manifold from where it subse-quently enters the combustion chamber and isburned.

3. EXHAUST EMISSION CONTROL SYSTEM The exhaust emission control system is a highlyeffective system which controls exhaust emis-sion while maintaining good vehicle performance.
SH010C1-E
2. EVAPORATIVE EMISSION CONTROL SYSTEM
The Evaporative Emission Control System is designed to prevent fuel vapours from escapinginto the atmosphere through the fuel tank venti-lation system.Whilst the engine is not running, fuel vapours generated inside the fuel tank are absorbed and stored in a charcoal canister. When the engine isstarted, the vapours stored in the canister aredrawn into the induction system through thepurge control solenoid valve and are subse-quently burned.The purge control solenoid valve is controlled bythe ECU; when the engine coolant temperatureis low or the engine is idling, the purge controlvalve is closed and fuel vapours remain stored inthe canister. Under normal running conditionswhen the engine is warm, the valve opens andthe vapours are drawn into the inlet tract andsubsequently burned in the combustion cham-ber. SH020A1-E CATALYTIC CONVERTOR OPERATING PRECAUTIONS Hyundai Coupe models are fitted with catalytic convertors which require special operating con-siderations. The catalytic convertor serves tooxidize certain noxious elements of the exhaustgases leaving the engine to reduce the level ofpollutants emitted from the vehicle and, providedthat care is exercised to prevent damage, thecatalyst will operate efficiently for the life of thevehicle.It is of the utmost importance that the followinginformation is read and understood by the ve-
