CATALYTIC  CONVERTOR  OP-
ERATION PRECAUTIONS
; For a Petrol engine
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  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
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 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 dealer for rectification. Simi-
larly,  the practice  of  certain  ignition
system  diagnosis procedures  which
involve  inducing  a  misfire  (cylinder
power balance tests for example) may
result in  catalyst damage.
Push or tow  starting of the vehicle is
to be avoided since unburnt fuel may
be  enter  the  catalyst  and  result  in
damage.
(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
extremely  high  temperatures   being
attained  within the  catalytic  conver-
tor,  and   although  the  convertor  is
fitted with heat shields, it is important
that  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  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.
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.
Catalytic  Converter
HTB178
Hyundai Getz  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.
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.
It is of the utmost importance that the
following information is  read and un-
derstood  by the  vehicle  operator  in
