may cause the catalytic converter to
overheat and thus
efficiency or even destroy it and
cause heat damage to the vehicle:

illuminated;
• Faulty ignition, running out of
fuel or spark plug disconnected
occurring as engine misfiring and
snatches when driving;
• Using leaded petrol;
• Using lubrication additives or
fuel which is not approved by
Renault;
• Loss of power;
• The fitting of non-recognised
security systems which have been
integrated into the fuel injection
system for immobilisation
purposes;
• Bump starting the vehicle, as
unburnt petrol in the system may
affect the catalyst if the car does
not start quickly. However, jump
starting with jump leads across
the battery is permissible.
