DO-IT-YOURSELF MAINTENANCE 6- 19
B145A02TB-EAT CHANGING THE POLLEN FIL-
TER (In Front of evaporator unit)(Not all models) The pollen filter is located in front of the evaporator unit behind the glove box. It operates to decrease pollutants fromentering the car and to filter the air.
1. Remove the adjusting pins on both
sides of the glove box to open half the glove box.

SG140D1-E Off Season Maintenance The air conditioning must be run for ten minutes or so weekly during periodswhen the system would not normally be used to ensure that the compressor and seals are lubricated. If this precautionis not observed the compressor seals may become stuck to the compressor shaft and damaged when the system isnext used resulting in a loss of refriger- ant and damage to the compressor.
3. Remove the filter cover to push theupside of the filter cover.

2. Remove the cable and the wiring from the filter cover.

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.

CATALYTIC CONVERTOR OP- ERATION PRECAUTIONS ; For a Petrol engine
Hyundai Getz models are fitted with
catalytic convertors which require special operating considerations. Thecatalytic convertor serves to oxidize certain noxious elements of the ex- haust gases leaving the engine toreduce the level of pollutants emitted from the vehicle and, provided that care 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 in
HTB5017Catalytic Converter order to prevent operational problems arising from damage to the catalyst.
Damage to the catalyst will result if
contamination occurs through the use of leaded fuel. Whilst the vehicle isfitted with a reduced diameter filler neck to prevent charging of the fuel tank with a leaded fuel pump nozzle,it is possible that the use of funnels or fuel cans will permit leaded fuel to be introduced into the fuel tank.
The catalyst is intolerant of unburnt
fuel 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 aHyundai dealer for rectification. Simi- larly, the practice of certain ignition system diagnosis procedures whichinvolve inducing a misfire (cylinder power balance tests for example) may result in catalyst damage.
For these reasons, it is advisable that
the exhaust gas emission be testedat each routine service with a gas analyzer having a Hydrocarbon mea- suring facility to ensure continuedreliability of the catalyst. Push or tow starting of the vehicle is to be avoided since unburnt fuel may enter the catalyst and result in dam-age. (Note, it is impossible to push or tow start a Hyundai model equipped with fuel injection since the fuel pumpsafety interlock will prevent the pump from operating under these conditions). Operation of the catalyst involves ex- tremely high temperatures being at- tained within the catalytic convertor,and although the convertor is fitted with heat shields, it is important that the vehicle is not parked over combus-tible or volatile material which may result in fire. If the above precautions are not ad- hered to and the catalyst becomes inoperative, the resultant increase in core temperature will result in a "meltdown" where the catalyst core will melt 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 vehicle is raised by means of a garage jack. Care must also be exercised to avoiddriving over road hazards or debris which may cause damage to the cata- lyst element.
