The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with
a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
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 warnings
The system warns the driver if one or
more tyres are flat by turning on the
warning light on the instrument
panel (together with a warning message
and an acoustic signal).
In this case, stop the vehicle as soon as
possible, check the inflation pressure
of each tyre and inflate to the cold tyre
pressure value prescribed for the
vehicle. The system will automatically
update and after receiving the tyre
pressure update 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 system to receive this
information.
TPMS operation faults
The system fault is indicated by the
corresponding warning light
, which
first flashes for 75 seconds and then
stays on continuously. 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.
If the space-saver wheel replaces a
tyre with a pressure lower than the
insufficient pressure limit, an acoustic
signal will be emitted and the
warning light will turn on at the next
start-up.
When the original tyre is repaired or
replaced and it is mounted back on
the vehicle to replace the space-saver
wheel, the TPMS will update
automatically and the warning light will
switch off, provided that the pressure of
none of the four tyres is below the
insufficient pressure limit. 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.
