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.

EMISSION CONTROL SYSTEMS 7-1

CONTROL SYSTEMS
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.
H020A01A-GAT
CATALYTIC CONVERTER (If Installed)
Catalytic Converter
SSA7020A
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.

SH010A1-E (Not all models) Depending upon the market for which the vehicle is destined, the emission control system will comprise one or more of the following emission controldevices.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control systemIn order that the proper functioning of the emission control systems may be ensured, it is recommended that the vehicle is inspected and maintainedby an authorized Hyundai dealer in accordance with the maintenance schedule in this manual. EMISSION CONTROL SYS- TEMS
SH010B1-E
1. CRANKCASE EMISSION CON- TROL SYSTEM The positive crankcase ventilation system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase byintroducing fresh air to the crankcase through the air cleaner where this mixes with blow-by gases and thenpasses through the PCV valve into the intake manifold from where it sub- sequently enters the combustionchamber and is burned.

2. EVAPORATIVE EMISSION
CONTROL SYSTEM
The Evaporative Emission Control
System is designed to prevent fuelvapours from escaping into the atmo-sphere through the fuel tank ventila- tion system. 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. Whilst the engine is not running, fuel vapours generated inside the fuel tankare absorbed and stored in a char- coal canister. When the engine is started, the vapours stored in thecanister are drawn into the induction system through the purge control so- lenoid valve and are subsequentlyburned.The purge control solenoid valve iscontrolled by the ECU; when the en-gine coolant temperature is low or the engine is idling, the purge control valve is closed and fuel vapours re-main stored in the canister. Under normal running conditions when the engine is warm, the valve opens andthe vapours are drawn into the inlet tract and subsequently burned in the combustion chamber.
