1FEATURES OF YOUR HYUNDAI
2FUEL RECOMMENDATIONS
B010A03A-GAT Use Unleaded Gasoline For Europe – For the optimal vehicle
performance, we recommend you to use unleaded gasoline with an octanerating of RON (Research Octane Num- ber) 95 /AKI (Anti Knock Index) 91 or higher.You may use unleaded gasoline with an octane rating of RON 91~94/AKI 87~90 but it may result in slight performancereduction of the vehicle. Except Europe – Unleaded gasoline
with a Pump Octane Rating of 87 (Re- search Octane Number 91) or higher must be used in Hyundai vehicle. If leaded gasoline is used, it will causethe catalytic converter to become inef-fective and the emission control sys- tem to malfunction. 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 Hyundai vehicle. NOTE:
o For some countries, Hyundai
vehicles are designed to use leaded gasoline. When you are going to use leaded gasoline,ask to Hyundai dealer whether leaded gasoline in your vehicle is available or not.
o Octane Rating of leaded gaso- line is same with unleaded one. B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grainalcohol) may be used in your Hyundai. However, if your engine develops driveability problems, the use of 100%unleaded gasoline is recommended. Fuels with unspecified quantities of alcohol, 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 your Hyundai. This type of fuel can reducevehicle performance and damage com- ponents of the fuel system.
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.

7EMISSION CONTROL SYSTEMS
2
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
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control systemIn order to assure the proper function of the emission control systems, it isrecommended that you have your car inspected and maintained by an au- thorized Hyundai dealer in accordancewith the maintenance schedule in this manual. EMISSION CONTROL SYS- TEMS
H010B01F-GAT 1. Crankcase Emission Control
System
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 induction system.
H010C01F-GAT
2. Evaporative Emission Control
System (If Installed)
The evaporative emission control sys-
tem is designed to prevent fuel va-pors from escaping into the atmo-sphere. H010D01A-AAT
3. Exhaust Emission Control
System
The exhaust emission control system is a highly effective system which controls exhaust emissions while maintaining good vehicle performace.
Canister While the engine is inoperative, fuel vapors generated inside the fuel tank are 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 ECM; when the en- gine coolant temperature is low, and during idling, it closes, so that evapo- rated fuel is not taken into the engine. After engine warm-up, during ordi-nary driving, it opens so as to intro- duce evaporated fuel to the engine.

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 a Hyundai authorised repairer 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.
SH010C1-E
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.
