EMISSION CONTROL SYSTEM
It is of the utmost importance that the following
information is read and understood by the
vehicle operator in order to prevent operational
problems arising from damage to the catalyst.
Damage to the catalyst will result if contamina-
tion occurs through the use of leaded fuel.
Whilst the vehicle is fitted with a reduced diam-
eter 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.
Operation of the catalyst involves extremely
high temperatures being attained within the
catalytic convertor, and although the convertor
is fitted with heat shields, it is important that the
vehicle is not parked over combustible or vola-
tile material which may result in fire.
If the above precautions are not adhered 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 sys-
tem.
The catalyst is intolerant of unburnt fuel and
therefore if an engine misfire condition exists,
damage to the catalyst will occur. It is impera-
tive that if a misfire condition develops, the
vehicle is immediately presented to a Hyundai
dealer for rectification. Similarly, the practice of
certain ignition system diagnosis procedures
whichinvolveinducingamisfire(cylinderpower
balance tests for example) may result in cata-
lyst damage.
For these reasons, it is advisable that the
exhaust gas emission be tested at each routine
service with a gas analyzer having a Hydrocar-
bon measuring facility to ensure continued
reliability of the catalyst.
Due to the fragile nature of the catalyst ele-
ment, it is important that damage 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 catalyst element.

EGR SYSTEM
;
For a diesel engine
This system helps control oxides of nitrogen by
recirculating a part of the exhaust gas into the
engine.
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).
H020D01S-GAT
CATALYTIC CONVERTER
; For a diesel engine
All Hyundai vehicles are equipped with oxida-
tion type catalytic converter to reduce the car-
bon monoxide, hydrocarbons and particulate
contained in the exhaust gas.
