❒ The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal
pressure loss of the tyre.
❒ The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices
with electronic sensors mounted on
the wheel rims to constantly monitor
the value of tyre pressure. The
sensors mounted on each wheel as
part of the valve stem transmit
various information of the tyres to
the receiver module, in order to
calculate the pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in
all four tyres are particularly
important.
Tyre pressure
monitoring system low
pressure warning
The system warns the driver if one
or more tyres are flat by switching
on the warning light
on the
instrument panel (together with a
warning message and an acoustic
signal).
The TPMS continues to advise the
driver of the low tyre pressure
condition until this is corrected; the
warning continues until the pressure
corresponds or exceeds the
pressure prescribed for the cold
tyres. When the tyre low pressure
control warning light
switches on
constantly, the inflation pressure
must be adjusted until it reaches the
pressure prescribed for cold tyres.
After the automatic update of the
system, the tyre pressure control
warning light switches off. You may
need to drive the vehicle for about
20 minutes at a speed higher than
20 km/h to allow the TPMS to
receive this information.
IMPORTANT In the case of deflation
of more than one tyre sequentially,
without switching off and on the
engine, from the second tyre
involved the acoustic signal is not
activated, only the dedicated signal
is shown on the display.
To prevent the signal from being
stored in the event of pressure loss
of a subsequent tyre (with
deactivation of the acoustic signal),
the ignition key must be turned to
MAR and then to STOP, each time
pressure is restored.
TPMS operation faults
The system fault is indicated by
warning light
which first flashes
for 75 seconds and then stays
on steadily. This can occur in any of
the following situations:
❒ interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.
❒ Application of tinted films which
interfere with the signals of the radio
waves.
❒ Presence of snow or ice on the
wheels or the wheel arches.
❒ Use of snow chains.
❒ Use of wheels/tyres not equipped
with TPM sensors.
❒ The space-saver wheel is not
equipped with the tyre pressure
control sensor. Therefore, the tyre
pressure is not controlled by the
system.
