TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the car.
Changes in outside temperature may
cause tyre pressure to vary. This means
that a decrease in the outside
temperature corresponds to a decrease
in the tyre pressure.
Tyre pressure must always be adjusted
according to the cold inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the car at a
standstill for at least three hours or a
travel shorter than 1.6 km after an
interval of three hours.
The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
The tyre pressure also increases while
driving the car: this is a normal
condition and does not require any
adjustment of the pressure.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 car for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
NOTE
❒The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒Therefore, the TPMS should not be
used as pressure switch while
adjusting the tyre inflation pressure.
❒Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency
and tyre tread life and may also affect
handling and braking performance
of the car.❒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.

GETTING TO KNOW YOUR CAR

WHEELS AND TYRES
Before embarking on a long trip, and
every two weeks, check the tyre
inflation pressure. Check the tyres when
cold.
131) 132) 133) 134) 135)
It is normal for the pressure to increase
when the car is used; for the correct
tyre inflation pressure, see “Wheels” in
the “Technical specifications” section.
Incorrect pressure causes abnormal
tyre wear fig. 128:
A normal pressure: tread evenly worn;
B low pressure: tread particularly worn
at the edges;
C high pressure: tread particularly
worn in the centre.The tyres must be replaced when the
tread is less than 1.6 mm thick. In
any case, follow the laws in force in the
country you are in.
IMPORTANT
For versions/markets, where provided,
the 4C may be equipped with
high-performance tyres able to
guarantee superior grip; this results,
however, in increased wear. Alfa
Romeo, together with Pirelli, has indeed
developed special tyres for 4C: a
dedicated series of Pirelli PZero,
initialled AR, meeting the technical
specifications necessary to get the car
best performance.
Take the following precautions to
prevent damage to the tyres:
❒avoid violent impact against the kerb,
potholes or obstacles as well as
driving for extended periods on
uneven road surfaces;
❒periodically check that the tyres have
no cuts in the side wall, abnormal
swelling or irregular tread wear;
❒avoid travelling with the car
overloaded. If a tyre is punctured,
stop immediately and change it;❒tyres age even if they are not used a
great deal. Cracks in the tread and
on the sidewalls are a sign of ageing.
Have the tyres checked by
specialised personnel if they have
been fitted for longer than 6 years;
❒if replaced, always fit new tyres,
avoiding those of dubious origin;
❒if a tyre is changed, also change the
inflation valve.
WARNING
131) The road holding qualities of
the car also depend on the correct
inflation pressure of the tyres.
132) If tyre pressure is too low, it
may overheat and be severely
damaged as a result.
133) Do not switch tyres from the
left to the right side and vice
versa, in order to prevent
inversion of the rotation direction.
134) Do not repaint alloy wheel rims
at temperatures higher than
150°C. The mechanical
characteristics of the wheels
could be compromised.

WHEELS
RIMS AND TYRES
Alloy rims. Tubeless radial carcass
tyres. All approved tyres are listed in the
Registration Document.
IMPORTANT If there are any
discrepancies between the Owner
Handbook and the Registration
Document, take the information from
the latter.
For safe driving, the car must be fitted
with tyres of the same make and type
on all wheels.
IMPORTANT Do not use air chambers
with tubeless tyres.
