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.
vehicle loaded asymmetrically on one
side, towing a trailer, damaged or worn
tyre, fitting the space-saver wheel,
use of the "Fix&Go Automatic"
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 flashes for about
75 seconds and then is continuously
on; at the same time, the display shows
a dedicated message. This warning is
displayed also after the engine has
been switched off and then on again if
the correct operating conditions are not
restored.

WARNING
56) The iTPMS is optimised for the original
tyres and wheels provided. iTPMS
pressures and alerts have been defined
according to the size of the tyres mounted
on the vehicle. Using equipment with
different size, type or kind may cause
irregular system operation or sensor
damage. Non-original spare wheels can
damage the sensor. Do not use tyre
sealant or balancing weights if the vehicle
is equipped with iTPMS as these may
damage the sensors.
57) If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
58) The iTPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not even to be
considered a replacement system for
maintenance or a safety system.
59) Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
60) The iTPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
61) The system only warns that the tyre
pressure is low: it is not able to inflate
them.
62) Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect your ability to drive the
vehicle safely.
63) Always refit the valve stem cap after
inspecting or adjusting tyre pressure. This
prevents dampness or dirt from entering
the valve stem and thus the pressure
control sensor from being damaged.
64) The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
iTPMS sensors; using sealants not
equivalent with that in the original kit may
adversely affect its operation. If sealants
not equivalent with the original ones are
used, it is recommended to have the
iTPMS sensor operation checked by a
qualified repair centre.
65) If the system signals a loss of pressure
on a specific tyre, it is recommended to
check the pressure on all four tyres.
