Fiat 500X Owner's Handbook Manual page 81

This warning is displayed also when
turning the engine off and on again until
the RESET procedure is carried out.
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
manually.
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 spare 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).
If the RESET is not carried out, in all
above cases, the warning light may
give false indications on one or more
tyres.
To carry out the RESET procedure,
with the vehicle stopped and the
ignition device at MAR, use the Main
Menu as follows:
go to "Vehicle info" and then to
"Reset tyre pressure";
press the "OK" and hold down (more
than 2 seconds);
the display will show the procedure
progress (with a graphic bar) till the
RESET is completed.
At the end of the RESET procedure
the display will show the "Reset
saved" message, indicating that the
self-learning has been started and you
will hear a beep. If the self-learning
procedure of the iTPMS system has
not been carried out correctly, you will
not hear any acoustic warning.
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.
Under special conditions (e.g. car
loaded asymmetrically on one side,
damaged or worn tyre, fitting the
space-saver spare wheel, use of
the "Fix&Go" tyre repair kit, fitting
snow chains, fitting different tyres on
the axles) the system may provide
false indications or be temporarily
deactivated.
If the system is temporarily deactivated
the warning light flashes for about
75 seconds and then is continuously
on; at the same time, the display
shows a warning message and the
symbols "– –" will appear next to the
shape of the car next to each tyre.
This warning is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored.
In the case of abnormal signals, it is
recommended to perform the RESET
procedure. If the indications appear
again after a successful RESET, check
that the tyres used on all four wheels
are the same and that the tyres are
not damaged. As soon as possible,
refit the standard tyre instead of the
space-saver spare wheel, remove the
snow chains, if possible, check correct
load distribution and repeat the RESET
procedure by driving on a clean,
tarmacked road. If the indications
persist, contact a Fiat Dealership.
WARNING
58) The system is an aid for car driving,
it DOES NOT warn the driver about
incoming cars outside of the detection
areas. The driver must always maintain
a sufficient level of attention to the traffic
