(1.95 bar), a temperature reduction of
19.4°F (−7°C) results in a decrease in tyre
pressure, bringing it to approximately
24 psi (1.65 bar).
This pressure is sufficiently low to
activate the warning light .
Heating of tyres due to driving the
car may increase tyre pressure up to
approximately 28.3 psi (1.95 bar), but
the warning light
will stay on. In this
situation, the warning light will switch off
only after the tyres are inflated to the
prescribed cold pressure value for the
car.
WARNING
53) The driving assistance systems are
designed to help driving the car. The driver
must always maintain a sufficient level of
attention to the traffic and road conditions
and for controlling the trajectory of the car.
54) The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
tyre, and correct maintenance: the system is
not used to signalling a possible tyre fault.
55) Tyre pressure must be checked with
tyres rested and 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. Repeat the check when the
tyres are cold.
56) Should one or more wheels be fitted
without sensors, the system will no longer
be available and a warning message will
be shown on the display, until wheels with
sensors are fitted again.
57) The TPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the car, braking with caution and
avoiding abrupt steering.
58) Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.
59) Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Dedicated Alfa Romeo Dealerships.
60) When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact an Alfa Romeo Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff. Contact
a Dedicated Alfa Romeo Dealership.
IMPORTANT
16) The Tyre Repair Kit, provided with the
car, is compatible with the TPMS sensors.
Using sealants different from that in the
original kit may compromise its operation.
If sealants not equivalent with the original
one are used, it is recommended to have
the TPMS sensor operation checked by a
qualified repair centre.
17) The TPMS is designed for original tyres
and wheels. The prescribed pressures and
consequent alarm thresholds set in the
TPMS are based on the dimensions of the
tyres fitted on the car. Using spare wheels
of a size, type and/or design different from
the original ones may cause an irregular
operation of the system and damage the
sensors. Aftermarket fitted wheels may
damage the sensors. Using aftermarket
tyre sealants may damage the Tyre
Pressure Monitoring System (TPMS) sensor.
If aftermarket tyre sealant is used it is
recommended to go to a Dedicated Alfa
Romeo Dealership to have the sensors
checked. After checking or adjusting the
tyre of the pressure, always refit the valve
cap to prevent humidity and dirt from
entering, these may damage the Tyre
Pressure Monitoring System sensor.
