FAULT SIGNALLING
Automatic gearbox faults are indicated by
the t warning light (A-fig. 141) on
the instrument cluster as follows:
– warning light glowing steadily
= maximum automatic gearbox oil temperature;
– warning light flashing = automatic
gearbox fault.
Turning the ignition key to MAR the warning
light should turn on and go out after
approx. 4 seconds.
If the warning light stays on or turns on
during travelling, it indicates a gearbox fault
(flashing) or overheated gearbox oil (glowing
steadily).

Warning light glowing steadily
If the warning light turns on and glows
steadily when the car is travelling, it indicates
that the gearbox oil has reached the
maximum established temperature.
The automatic control system provides an
emergency programme.
It is however advisable to stop the car,
move the lever to P or N and let the engine
idle until the warning light goes out. Resume
driving without demanding high performance
from the engine.
If the warning light comes on again, it is
necessary to stop again with the engine
idling until it goes out again.
If the interval between one lighting up of
the warning light and the next is below 15
minutes, you are advised to stop the car,
turn off the engine and wait for the enginegearbox
unit to cool down completely.
Warning light flashing
The flashing of the warning light when travelling
indicates a fault in the automatic gearbox.
The automatic control system provides an
emergency programme. Under these circumstances,
you are advised to stop the car
and turn off the engine; in fact, the next
time the engine is started, the self-diagnostics
system could cut off the fault which
will, however, be memorised by the electronic
control device.
Conversely, if the fault remains (warning
light (A- fig. 141) flashing), it is necessary
to select the gears manually as if driving
a car with mechanical gearbox, bearing
in mind that the only two speeds
available are the 2nd and 4th gear, as shown
in the table below:
