iTPMS System
(indirect Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
48)
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.
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.
Under special conditions (e.g. vehicle
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, use of
the “Fix&Go” quick tyre repair kit,
fitting snow chains, fitting different
tyres on the axles) the system may
give false indications or be temporarily
deactivated.
If the system is temporarily
deactivated, the warning light
nflashes for about 75 seconds and then
is continuously on; at the same time,
the display shows a dedicated
message.
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored. 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).
If the Reset procedure is not carried
out, in all above cases, the
nwarning light may give false indications
on one or more tyres.
To carry out the Reset procedure, with
the vehicle 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
“Reset saved” message, indicating
that the self-learning has been started.
If the iTPMS self-learning is not
correctly executed, the message is not
displayed.
