Opel Vivaro Manual page 87

Stopping the journey or switching off
the engine during cleaning is not
recommended.
Caution
If the cleaning process is
interrupted more than once, there
is a great risk of provoking severe
engine damage.
Cleaning takes place quickest at high
engine speeds and loads.
The control indicator 8 extinguishes
as soon as the self-cleaning
operation is complete.
If control indicator 8 fails to
extinguish or 8 illuminates in
conjunction with A, consult
a workshop to have the cause of the
fault remedied.
Control indicator A 3 67.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed
on pages 3 101, 3 142 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine
performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact
a workshop immediately.
