Catalytic converter, exhaust
emissions
Ca taly tic conv er ter for petrol engines
Leaded fuel will damage the catalytic
converte r and parts of the elec tronic
system, thereby rendering them
inoperative.
On vehicles with a catalytic converter, the
fuel tank filler neck is of a narrow d esign so
that a dispensing pump for leaded fuel
cannot be inserted.
Damage to the catalytic converter or the
vehicle may result if the follow ing points
are not observed:
z If the engine misfires or runs roughly
after a cold start, the engine power has
reduced significantly or other unusual
opera ting problems occur that indicate a
fault in the ignition system, please
contact a workshop as quickly as
possible. Drive at a slower speed and
with less engine revs for a short time if
necessary.
z If unburned fuel enters the catalytic
converter, this may result in overheating
and irreparable damage to the catalytic
converter.
You should therefore avoid frequent
coldstarts, unnecessarily long use of the
starter when setting off, running the tank
dry (an irregular fuel supply leads to
overheating) and starting the engine by
pushing or towing.
z If the control indicator Z for exhaust
emission flashes, lift your foot off the
accelerator until the indicator stops
flashing and is steadily illuminated.
Contact a workshop immediately.

Damage to the catalytic converter or the
vehicle m ay result if the following points
are not observed :
z Consult a workshop as quickly as
possible in the event of irregular engine
running, a significant loss of engine
power or other unusual malfunctions. If
necessary, driving may be continued for
a short time at a low speed and with a
low engine speed.
