iTPMS System (indirect
Tyre Pressure
Monitoring System)
77) 78) 79) 80) 81) 82)
DESCRIPTION
The vehicle can be equipped with the
iTPMS (indirect Tyre Pressure
Monitoring System) which monitors the
tyre inflation status thanks to wheel
speed sensors.
To access the iTPMS screens ( fig. 51 -
fig. 52), press the TRIP button.
The fig. 52 screen will be displayed only
if one or more tyres are flat.
Correct tyre pressure (versions with
colour display)
If pressure of all the tyres corresponds
to the correct value, the display shows
the following screen fig. 51.
Low tyre pressure
The system warns the driver if one or
more tyres are flat by switching on
the warning light on the instrument
panel. Furthermore, the display will
show "KO" beside the tyres fig. 52
along with a warning message.

RESET PROCEDURE
The iTPMS needs an initial "self-
learning" phase (with length depending
on the driving style and road conditions:
optimal conditions being driving on a
straight road at 80 km/h for at least 20
minutes) which starts when the Reset
procedure is carried out.
The Reset procedure must be carried
out:
each time tyre pressure is modified;
when even only one tyre is changed;
when tyres are rotated/inverted;
when the space-saver wheel is
fitted.
Before carrying out the RESET
procedure, inflate the tyres to the rated
pressure values specified in the inflation
pressure table (see "Wheels" paragraph
in the "Technical specifications"
chapter).
F0S0496 If the RESET procedure is not carried
out, in all above cases, the
light may give false indications on
one or more tyres.
To carry out the RESET procedure, with
the car stopped and the ignition key
at MAR, use the setup menu (see the
description of the "Display" paragraph).
At the end of the Reset procedure,
the display will show the message
"Reset saved", indicating that
F0S0506
self-learning has started.
If the iTPMS self-learning is not
correctly executed, the message is not
displayed.
OPERATING CONDITIONS
The system is active for speeds above
15 km/h.
In a few situations such as sporty
driving, particular conditions of the road
surface (e.g. icy, snowy, unsurfaced
roads...) the signalling may be delayed
or partial in detecting the contemporary
deflation of more than one tyre.
