If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and warning
tand the corresponding
warning message will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.
GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car front or rear part, under certain cir-
cumstances are not detected and could
therefore cause damages to the car or
be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Rear sensors are reactivated automati-
cally when removing the trailer cable
plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by turning on
of warning light
t(where provided)
on the instrument panel (on certain ver-
sions together with the message on the
display) (see section “Warning lights
and messages”).
Rear sensors operation
is deactivated automat-
ically when the trailer
electric cable plug is fitted into
the car tow hook socket.

AND

The car can be equipped with the
T.P.M.S. (Tyre Pressure Monitoring Sys-
tem). This system consists of a radio-fre-
quency sensor, installed on each wheel
(on the rim inside the tyre) that sends
pressure information to the control unit.IMPORTANT NOTES
Failure indications will not be stored and
therefore will not be displayed when
turning the engine off and on again. If
failure persists, the control unit will send
warning indications to the instrument
panel only after a few seconds when the
car is moving.
Tyre pressure should be checked with
tyres cold. Should it become necessary
for whatever reason to check pressure
with hot tyres, do not reduce pressure
although it is higher than the prescribed
value but repeat the check when tyres
are cold (see section “Wheels” in sec-
tion “Technical Specifications”).
TYRE PRESSURE MONITORING SYSTEM -
T.P.M.S. (where provided)
(optional for versions/
markets where applicable)
The T.P.M.S. does not
exempt the driver from
checking tyre pressure, includ-
ing the space-saver spare
wheel (where provided) at
regular intervals.
WARNING
T.P.M.S. cannot indicate sudden tyre
pressure drops (e.g.: tyre burst). In this
event, brake the car cautiously and
avoid sudden steering.
The T.P.M.S. system requires special
equipment. Consult Alfa Romeo Autho-
rized Services to know what type of ac-
cessories are compatible with the sys-
tem (wheels, wheel caps, etc.). Using
other accessories could cause system
malfunctioning. Due to inflation valve
special characteristics, use only tyre re-
pair sealants approved by Alfa Romeo;
other sealants could cause system mal-
functioning.
