case, stop the car, braking with caution and
avoiding abrupt steering.
80) 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.
81) Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Alfa Romeo Dealerships.
82) 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
an Alfa Romeo Dealership.
IMPORTANT
19) The system may have limited operation
or not work at all in weather conditions such
as: heavy rain, hail, thick fog, heavy snow.
20) The section of the bumper in front the
sensor must not be covered with stickers,
auxiliary headlights or any other object.
21) System intervention might be
unexpected or delayed when other cars
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the car.
22) Operation can be adversely affected by
any structural change made to the car, such
as a modification to the front geometry,
tyre change, or a heavier load than the
standard load of the car.
23) Incorrect repairs made on the front
part of the car (e.g. bumper, chassis) may
alter the position of the radar sensor, and
adversely affect its operation. Go to an Alfa
Romeo Dealership for any operation of this
type.
24) Do not tamper with or carry out any
intervention on the radar sensor or on the
camera on the windscreen glass. In the
event of a sensor failure, contact an Alfa
Romeo Dealership.
25) Do not wash with high-pressure jets in
the bumper lower area: in particular do
not operate on the system's electrical
connector.
26) Be careful in the case of repairs and
new paintings in the area around the sensor
(panel covering the sensor on the left side
of the bumper). In the event of a frontal
collision the sensor may automatically
deactivate and display a warning to indicate
that the sensor needs to be repaired. Even
without a malfunction warning, deactivate
the system operation if you think that the
position of the radar sensor has changed
(e.g. due to low-speed frontal collision as
during parking manoeuvres). In these cases,
go to an Alfa Romeo Dealership to have the
radar sensor realigned or replaced.
27) When towing a trailer, a car or during
loading manoeuvres on a car transporter
(or in car for transport), the system must be
deactivated via the Connect system.
28) 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.
29) 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 an 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.
