The catalyst is intolerant of unburnt fuel and

is not parked over combustible or volatile mate-

If the above precautions are not adhered to and

Care must also be exercised to avoid driving
over road hazards or debris which may cause
damage to the catalyst element.
For these reasons, it is advisable that the ex-
haust gas emission be tested at each routine
service with a gas analyzer having a Hydrocar-
bon measuring facility to ensure continued reli-
ability of the catalyst.
Push or tow starting of the vehicle is to be
avoided since unburnt fuel may be enter the
