OWNER MAINTENANCE
21CHANGING THE POLLEN FILTER
B145A01A-EAT
(For Evaporator and Blower
Unit) (Not all models) The pollen filter is located in front of the evaporator unit behind the glove box.It helps to decrease pollutants from entering the car.
1. Open the glove box and remove the
adjusting pins on both sides of the glove box. HLC2096-D
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.
2. Remove the cable and the wiring
from the filter cover.
3. Remove the filter cover by pushing the upper end of the filter cover. HLC2097-D

2EMISSION CONTROL SYSTEMS
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 con-trol devices.
1) Crankcase emission control sys-
tem
2) Evaporative emission control sys-
tem
3) Exhaust emission control system In order that the proper functioning of the emission control systems may be ensured, it is recommended that thevehicle is inspected and maintained by an authorized Hyundai dealer in accordance with the maintenanceschedule in this manual. SH010B1-E
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 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 fuel vapours from escaping into the atmo- sphere through the fuel tank ventila-tion system. Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored ina charcoal canister. When the engineis started, the vapours stored in the canister are drawn into the induction system through the purge control so-lenoid valve and are subsequently burned. Purge Control Solenoid Valve
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. Undernormal running conditions when the engine is warm, the valve opens and the vapours are drawn into the inlettract and subsequently burned in the combustion chamber.

System
The exhaust emission control system
is a highly effective system which controls exhaust emission while main- taining good vehicle performance. SH020A1-E
; For a petrol engine
Hyundai Accent models are fitted with
catalytic convertors which requirespecial 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 inorder 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 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 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 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 that
the exhaust gas emission be tested at each routine service with a gas analyzer having a Hydrocarbon mea-suring facility to ensure continued reliability of the catalyst.

H020D01S-GAT
; For a diesel engine
All Hyundai vehicles are equipped with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.
H020C01S-GAT
; For a diesel engine
This system helps control oxides ofnitrogen by recirculating a part of theexhaust gas into the engine.
Care must also be exercised to avoiddriving over road hazards or debriswhich may cause damage to the cata- lyst element.
Push or tow starting of the vehicle is to be avoided since unburnt fuel maybe enter the catalyst and result in 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 vehicle is raised by means of a garage jack.
