Catalytic converter for petrol
engines
Leaded fuel will damage the catalytic
converter and parts of the electronic
system, rendering them inoperative.
Use of high-quality fuels other than those
specified on page 121 (e.g. LRP
1)
) could
damage the catalytic converter.
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 Consult a workshop, such as your
Vauxhall Authorised Repairer, 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 with a low engine speed.
z If unburnt fuel enters the catalytic
converter, this may result in overheating
and irreparable damage to the catalytic
converter.
You should therefore avoid
unnecessarily long use of the starter
when starting-off, running the tank dry
(an irregular fuel supply will lead to
overheating) and starting the engine by
pushing or towing.
z If the exhaust emission control
indicator Z flashes, slow down until the
flashing stops and the control indicator
is steady. Contact a workshop
immediately. We recommend your
Vauxhall Authorised Repairer.
