Catalytic Convertor Operation Precautions ; For a petrol engine
HFC505
Hyundai Matrix models are fitted with
catalytic convertors which require spe- cial operating considerations. The cata- lytic convertor serves to oxidize cer-tain noxious elements of the exhaust gases leaving the engine to reduce the level of pollutants emitted from thevehicle and, provided that care is ex- ercised to prevent damage, the cata- lyst will operate efficiently for the lifeof the vehicle.
Catalytic Converter It is of the utmost importance that the
following information is read and un- derstood by the vehicle operator in order 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 isfitted with a reduced diameter filler neck to prevent charging of the fuel tank with a leaded fuel pump nozzle, itis possible that the use of funnels or jerry 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 a Hyundai authorised repairer for rectifi- cation. Similarly, the practice of cer-tain ignition system diagnosis proce- dures which involve inducing a misfire (cylinder power balance tests for ex-ample) may result in catalyst damage. For these reasons, it is advisable thatthe exhaust gas emission be tested ateach routine service with a gas ana- lyzer having a Hydrocarbon measuring facility to ensure continued reliabilityof the catalyst.Push or tow starting of the vehicle is tobe avoided since unburnt fuel may beenter the catalyst and result in dam- age. (Note, it is impossible to push or tow start a Hyundai model equippedwith fuel injection since the fuel pump safety 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 thatthe 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 incore temperature will result in a "melt down" where the catalyst core will melt and subsequently may block the ex-haust system.

HA1409Spare tyre SI060A1-E TYRE BALANCING Incorrect tyre balance will cause steer- ing vibration and uneven tyre wear. The vehicle tyres are balanced during production but may need further bal-ancing throughout the life of the tyres.It is recommended that the tyres bebalanced on the car for best results and that the tyres are balanced when- ever they have been removed from thewheel for repair.
I060A01FC-EAT TYRE ROTATION The tyre wear characteristics will vary between each tyre dependant upon theconditions of use. It is normal for the front tyres to wear more rapidly than those fitted to the rear of the vehicleand therefore tyre rotation will provide a means of helping to ensure an even wear rate across the tyre set. Forvehicles fitted with radial ply tyres, rotation should be confined to front to rear tyre alternation. It is not recom-mended that radial ply tyres be rotated from side to side. NOTE:
o Do not use the temporary spare
tyre for tyre rotation.
o Aluminium wheels which are not supplied as Original Equipment should not be mixed on the same vehicle with the original steel wheels. However, it is acceptable that the steel spare wheel be used in conjunction with Original Equipment aluminium wheels since the offset of both wheels is compatible. Radial and cross ply tyres should not be mixed on the same vehicle.
