CHECKING THE CLUTCH FLUID
SG130A1-C
(Not all models)To Check the Clutch Fluid
The clutch fluid level in the master cylinder should be checked when performing other under bonnet checks. The system should be checked forleakage at the same time.Ensure that the clutch fluid level isalways between the "MAX" and "MIN" level markings on the fluid reservoir. Fill as required. Fluid loss indicates aleak in the clutch system which should be inspected and repaired immedi- ately.
HGK5012
SG120D1-E Brake Fluid Level The fluid level in the brake fluid reser- voir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of thereservoir. If the level is at or below the "MIN" mark, fluid should be added having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirt is not allowed to enter the system. It should be borne in mindthat the brake fluid level will decrease slightly as the friction linings of the pads and shoes become worn andthat this is a normal condition.
WARNING:
Brake fluid is hygroscopic and should never be stored in an un- sealed container. The presence ofwater in the braking system will cause vapour locks and increase the possibility of brake fade alongwith promoting corrosion within the braking system. The brake fluid must be changed at the specifiedtime or mileage interval to ensure continued safe operation of the system. Brake fluid will cause rapidand serious damage to paintwork. If accidental spillage occurs, the affected area must be rinsed withwater immediately. Do not allow brake fluid to come into contact with the eyes or to be ingestedand ensure that fluid is safely stored away form the reach of chil- dren.

7EMISSION CONTROL SYSTEMS
2
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.

3CATALYTIC CONVERTOR
SH020A1-E Hyundai Coupe models are fitted with catalytic convertors which requirespecial operating considerations. The catalytic convertor serves to oxidize certain noxious elements of the ex-haust gases leaving the engine to reduce the level of pollutants emitted from the vehicle and, provided thatcare is exercised to prevent damage, the catalyst will operate efficiently for the life of the vehicle. It is of the utmost importance that the following information is read and un- derstood by the vehicle operator inorder to prevent operational problems arising from damage to the catalyst. Damage to the catalyst will result if contamination occurs through the useof leaded fuel. Whilst the vehicle is fitted with a reduced diameter filler neck to prevent charging of the fueltank with a leaded fuel pump nozzle, it is possible that the use of funnels or jerry cans will permit leaded fuel to beintroduced into the fuel tank.The catalyst is intolerant of unburntfuel and therefore if an engine misfirecondition exists, damage to the cata- lyst will occur. It is imperative that if a misfire condition develops, the ve-hicle is immediately presented to a Hyundai dealer for rectification. Simi- larly, the practice of certain ignitionsystem diagnosis procedures which involve inducing a misfire (cylinder power balance tests for example) mayresult in catalyst damage.For these reasons, it is advisable thatthe exhaust gas emission be tested at each routine service with a gas analyzer having a Hydrocarbon mea-suring facility to ensure continued re- liability of the catalyst. Push or tow starting of the vehicle is to be avoided since unburnt fuel may be enter the catalyst and result in
Catalytic Converter
HGK5061 damage. (Note, it is impossible to push or tow start a Hyundai modelequipped with fuel injection since the fuel pump safety interlock will prevent the pump from operating under theseconditions).Operation of the catalyst involvesextremely high temperatures beingattained within the catalytic conver- tor, and although the convertor is fitted with heat shields, it is importantthat the vehicle is not parked over combustible or volatile material which may result in fire.If the above precautions are not ad-hered to and the catalyst becomesinoperative, the resultant increase in core temperature will result in a "melt down" where the catalyst core willmelt and subsequently may block the exhaust system. Due to the fragile nature of the cata- lyst element, it is important that dam- age does not occur when the vehicleis raised by means of a garage jack. Care must also be exercised to avoid driving over road hazards or debriswhich may cause damage to the cata- lyst element.

I030A01GK-EAT TYRE PRESSURES In modern high-speed motoring, cor- rect tyre pressures are vitally impor- tant. Incorrect tyre pressures can af- fect vehicle safety by causing re-duced adhesion, steering response and tyre failure through overheating. The tyre pressure must only be checked when the tyres are cold. Thecorrect tyre pressures are indicated on the label affixed to the drivers door pillar and below.
Tyre pressures should be increased
by 3 psi when the vehicle is drivenfully laden or under conditions of sus-tained high speed motoring.
