Catalytic Converter, Exhaust Emissions - Opel Antara Owner's Manual

Catalytic converter, exhaust
emissions
Catalytic converter for petrol engines
Leaded fuel will damage the catalytic
converter and parts of the electronic
system, thereby rendering them
inoperative.
On vehicles with a catalytic converter, the
fuel tank filler neck is of a narrow design so
that a dispensing pump for leaded fuel
cannot be inserted.
Damage to the catalytic converter or the
vehicle may result if the following 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
operating 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 cold
starts, 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 for exhaust
emissions Z flashes, lift your foot off the
accelerator until the control indicator
stops flashing and is steadily lit. Contact
a workshop immediately.
Control indicator Z for exhaust
emissions - see pages 74, 134.
Driving and operation
Catalytic converter for diesel engines
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed:
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.
