Advice for Emergency Situations
Exhaust system overheating alarm devices
(“Slow Down” function)
If the engine is running unevenly resulting in exhaust system
overheating, the “Slow Down” function is activated: a special
symbol (see page 149) appears on the TFT display accompanied by
a message.
The message varies according to three alarm levels:
sTemperature high: “Catalysts temp. high. Slow down”.
sTemperature too high: “Catalysts temp. too high. Engine
performance limited”.
sCatalytic converter temperature system failure: “Catalysts temp.
not plausible. Go to dealer slowly”.
Displaying of the message is controlled by the thermistor via the
engine control ECU.
Warning
Incorrect use of the vehicle may cause the “Slow Down”
function to be activated.
Warning
If the temperature is high:
slow down immediately so that the exhaust system temperature
decreases.
Warning
If the temperature is too high:
the temperature in the catalytic converters has reached a
dangerous level and could damage them; if you continue to
drive, the engine control ECU intervenes and reduces the
torque produced by the engine.
The torque limit remains active until the catalytic converter
temperature goes down to normal operating values.
Warning
If catalytic converter temperature system failure information is
displayed:
- the engine control ECU intervenes and reduces the torque
produced by the engine;
-
the driver must slow down and slo
wly drive to the nearest
Ferrari Service Network to have the engine parameters
checked.
Warning
If the EOBD warning light (see page 149) comes on at the same
time as the “Slow Down” message, go to the Ferrari Service
Network to have the ECU error memory checked. Do not
proceed in any other way.
