Ca talytic converter for petrol engines
Leaded fuel will damage the catalytic
converte r and parts of the elec tronic
system, thereby rendering them
inoperative.
High qua lity fuels other than those listed on
pages 114 and 175 (e.g. LRP
1)
) could
dam age the catalytic converter.
Damage to the catalytic converter or the
vehicle may result if the follow ing points
are not observed:
z Consult a workshop as quickly as
possible in the event of misfiring,
irregular engine running following a cold
start, a significant loss of engine power
or other unusual malfunctions which
may indicate a fault in the ignition
system. If necessary, driving may be
continued for a short time at a low speed
and w ith a low engine sp eed.
Irregular engine running and lack of
power when the Electronic Stability
Program (ESP) kicks in are for
opera tional reasons and can be
ignored ā see page 119.
z If unburned fuel enters the catalytic
conv erter, this may result in overheating
and irreparable damage to the c atalytic
converter.
You should therefore avoid
unnecessarily long use of the starter
when starting-off, running the tank dry
(an irregular fuel supply w ill lead to
overhea ting) and starting the engine by
pushing or towing.
z If the emission control ind ic ator Z
flashes, slow down until the flashing
stops and the control indicator is steady .
Consult a workshop immediately.
