SG220A1-E ELECTRIC COOLING FANS
WARNING:
The cooling fan is controlled by en- gine coolant temperature and maysometimes operate even when the engine is not running. Use extreme caution when working near theblades of the cooling fan so that you are not injured by a rotating fan blade. As the engine coolant tem-perature decreases, the fan will auto- matically shut off. This is a normal condition. The engine cooling fan should operate before the temperature gauge reachesthe upper portion of the scale and the condenser fan should operate when- ever the air conditioning is in use. SG230B1-E POWER STEERING HOSES Power steering hoses should be checked for damage, deterioration and leakage at each service.
NOTE: Grinding noise from power steering pump may be heard immediately after the engine is started in extremelycold condition (below -4°F). If the noise stops during warm up, there is no abnormal function in the system.This is due to a power steering fluid characteristic in extremely cold con- ditions. FLUID RECOMMENDATION Only automatic transmission fluid meet- ing the specification of Dexron 2 should be used in the power steering system.SG230A2-E POWER STEERING FLUID LEVEL The power steering fluid level should be checked daily.To check the power steering fluid level, be sure the ignition is "OFF", then check to make certain that the powersteering fluid level is between the "MAX" and "MIN" level markings on the fluid reservoir.

7- 2 EMISSION CONTROL SYSTEMS
SH010A1-E EMISSION CONTROL SYSTEMS (Not all models) Depending upon the market for which the vehicle is destined, the emissioncontrol system will comprise one or more of the following emission con- trol devices.
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. SH010B1-E
1. Crankcase emission
controlsystem
The positive crankcase ventilation
system is employed to prevent airpollution caused by blow-by gasesbeing emitted from the crankcase by introducing fresh air to the crankcase through the air cleaner where thismixes with blow-by gases and then passes through the PCV valve into the intake manifold from where it sub-sequently enters the combustion chamber and is burned.
SH010C1-E
2. Evaporative emission control
system
The Evaporative Emission Control
System is designed to prevent fuel vapours from escaping into the atmo- sphere through the fuel tank ventila- tion system. SH010D1-E
3. Exhaust emission con trol
system
The exhaust emission control system
is a highly effective system whichcontrols exhaust emission while main- taining good vehicle performance. Whilst the engine is not running, fuel
vapours generated inside the fuel tank are absorbed and stored in a char-coal canister. When the engine is started, the vapours stored in the canister are drawn into the inductionsystem through the purge control sole- noid valve and are subsequently burned.
The purge control solenoid valve is
controlled 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.
