6-12 SG120A1-E BRAKE SYSTEM CHECKING CAUTION: Correct operation of the braking system is essential to the safe operation of the vehicleand therefore, any maintenance operationsother than those listed below should be en-trusted to a Hyundai dealer. SG120C2-E Brake Fluid Recommendations Only brake fluid conforming to DOT 3 or DOT 4 specifications or higher may be used in thebraking system. Care should be taken to ob-serve the instructions and precautions printedupon the container. SG120D1-E Brake Fluid LevelThe fluid level in the brake fluid reservoir should be checked periodically. The level should bebetween the "MIN" and "MAX" marks on the sideof the reservoir. If the level is at or below the"MIN" mark, fluid should be added having care-fully cleaned the area surrounding the reservoircap to ensure that dirt is not allowed to enter thesystem. It should be borne in mind that the brakefluid level will decrease slightly as the frictionlinings of the pads and shoes become worn andthat this is a normal condition.
higher mark. If additional fluid is required, thisshould be poured into the transaxle through thedipstick tube with the aid of a suitable funnel. WARNING: The cooling fan is controlled by engine cool-ant temperature and may sometimes operateeven when the engine is not running. Useextreme caution when working near the bladesof the cooling fan so that you are not injuredby a rotating fan blade. As the engine coolanttemperature decreases, the fan will automati-cally shut off. This is a normal condition.
CAUTION:The automatic transaxle unit is a precisionengineered assembly and correct operationis dependant upon the exclusion of dirt andlint from the unit. Therefore, it is imperativethat only lint free cloth (eg nylon) is used forwiping the dipstick and that the area aroundthe dipstick is thoroughly clean prior to levelchecking or adding fluid. Fluid Capacity The total fluid capacity of the transaxle unit is 7.8 litres.

EMISSION CONTROL SYSTEM 7-1
SH010A1-E EMISSION CONTROL SYSTEMS (Not all models) Depending upon the market for which the vehicleis destined, the emission control system willcomprise one or more of the following emissioncontrol devices. (1) Crankcase emission control system (2) Evaporative emission control system(3) Exhaust emission control system In order that the proper functioning of the emis- sion control systems may be ensured, it isrecommended that the vehicle is inspected andmaintained by an authorized Hyundai dealer inaccordance with the maintenance schedule inthis manual.

CONTROL SYSTEM
SH010B1-E
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.
SH010D1-E
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-
