pressure value, shown on the display or
in the dedicated TPMS menu.
NOTE Some external factors (e.g.
external temperature, etc...) could
affect the information reported on the
instrument panel by the TPMS.
The tyre inflation pressure and the "low
pressure" reporting threshold could
change depending on the environmental
conditions.
TPMS TEMPORARILY DISABLED
TPMS check message
If a system failure is present, the
warning light
flashes for about 75
seconds and then stays on solid. An
acoustic signal is also emitted.
On some versions, a dedicated message
and dashes ("– –") instead of the
pressure value are shown on the display,
to indicate the impossibility of detecting
the sensor.
When the ignition device is set to STOP
and then back to MAR, the warning
sequence repeats provided that the
failure is still resent.
The warning light
switches off when
the failure condition disappears and,
on some versions, the pressure value is
displayed again in place of the dashes.
A fault in the system could occur in the
following cases:
intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated
by a dedicated message on the display.
The warning will disappear automatically
as soon as the radio-frequency
interference ceases to affect the system;
aftermarket application of coloured
films on the windows that interfere with
the radio waves emitted by the TPMS;
accumulation of layers of snow or ice
on the wheels or the wheel arches;
using snow chains;
use of rim/tyre assemblies without
sensors for TPMS;
the space-saver spare wheel is
not equipped with the tyre pressure
monitoring sensor. Therefore, the tyre
pressure is not controlled by the system.
NOTE The car can be equipped with
TireKit tyre repair kit, space-saver spare
wheel or full-size spare wheel (with or
without original TPMS sensor to measure
tyre pressure).
After the punctured tyre has been
repaired with the original tyre sealant
contained in the TireKit, the previous
condition must be restored, so that the
warning light
is off during normal
driving.
Space-saver spare wheel (where
provided): the space-saver spare wheel is
not equipped with a TPMS sensor. Once
fitted, while driving, the warning light
comes on
(flashing for about 75
seconds, and then solid). This condition
lasts until a wheel equipped with an
original TPMS sensor is fitted on the
vehicle.
Full size spare wheel (without TPMS
sensor): once fitted, while driving, the
warning light
comes on (flashing for
about 75 seconds, and then solid). This
condition lasts until a wheel equipped
with an original TPMS sensor is fitted on
the vehicle. The system is then restored
and the warning light
switches off.
Full size spare wheel (with TPMS
sensor): once fitted, while driving, the
warning light
switches off.
WARNING In all the above-mentioned
cases it is advisable to check the spare
wheel tyre pressure before starting
driving.
NOTE If the tyres are replaced, driving
the car for short stretches, some time
might be needed before the system is
restored.
