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  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 misfire
condition 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 that
the 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
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 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 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 "melt
down"  where  the  catalyst  core  will
melt and subsequently may block the
exhaust system.
Catalytic  Converter
OGK076501
Hyundai Coupe models are fitted with
catalytic   convertors   which  require
special 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  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
order to prevent operational problems
arising from  damage to the  catalyst.
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 avoid
driving  over road  hazards  or debris
which may cause damage to the cata-
lyst element.
