Ferrari F430 SPIDER Owner's Manual page 127

Metallic-type catalytic converters are
utilised on this vehicle.
The system is made up of two pre-
catalytic converters and two main catalytic
converters.
The catalytic converters reduce the
emission of HC, CO and NOx into the
atmosphere.
Each exhaust manifold contains a pre-
catalytic converter which, thanks to its
proximity to the gas outlet from the
combustion chamber, assures faster heating
and greater efficiency in exhaust emission
reduction during the phases immediately
following engine start-up.
The front oxygen sensor and the
thermocouple are installed on the
manifolds, one at the inlet and one at the
outlet of the pre-catalytic converter. The
rear oxygen sensor is installed at the outlet
of the main catalytic converter.
To prevent serious damage to the
catalytic converters, it is essential that
only unleaded fuel be used.
Do not park the vehicle over paper, dry
grass or leaves, or flammable materials that
could catch fire if they come into contact
with hot parts of the exhaust system.
Exhaust system overheating alarm
devices
If the engine malfunctions with consequent
high temperature in the exhaust system,
the red warning light on the multi-function
display, showing the words SLOW DOWN
will flash or stay on fixed.
The symbol activation is
SLOW DOWN
controlled by the thermocouple via the
Motronic ECU.
If the warning light flashes,
the catalytic converter temperature is too high.
Slow down immediately and go to a
workshop to have the malfunction corrected.
If the warning light remains on,
the temperature in the catalytic converters has
reached a dangerous level and could damage
them. If driving is continued, the injection-
ignition system ECU will intervene by cutting
off the fuel supply to the injectors.
6 - Technical Information
Stop the vehicle and have it towed to a
workshop to have the malfunction repaired.
Ferrari is not liable for any damage to
property or personal injury arising from
failure to comply with the warnings stated
above.
