Alfa Romeo Giulia 952 D-SEDAN 2016 Owner's Handbook Manual page 78

vehicle may increase tyre pressure up to
approximately 1.95 bar (28.3 psi), 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.
IMPORTANT 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
vehicle. 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
pressure, always refit the valve cap to
prevent humidity and dirt from entering,
these may damage the Tyre Pressure
Monitoring System sensor.
INSUFFICIENT TYRE PRESSURE
INDICATION
If an insufficient pressure value is
detected on one or more tyres, the
warning light on the instrument panel
76
switches on and the dedicated messages
are shown on the display. The system also
highlights the tyre or tyres with
insufficient pressure graphically. An
acoustic signal is also emitted.
In this case, stop the car, check the
inflation pressure of each tyre and inflate
them to the correct cold inflation
pressure value, shown on the display or in
the dedicated TPMS menu.
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.
A dedicated message and dashes "– –"
instead of the pressure value are shown
on the display, to indicate that detection
is impossible.
When the ignition device is set to STOP
and then back to ON, the indication
sequence repeats provided that the
failure is still resent.
The warning light switches off when
the failure condition disappears and the
pressure value is displayed again in place
of the dashes.
A fault in the system could occur in the
following cases:
strong radio-frequency noises could
hinder the regular operation of the TPMS.
This condition will be indicated by a
dedicated message on the display. The
message 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;
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.
TPMS deactivation
The TPMS can be deactivated by
replacing the wheels equipped with
TPMS with others that are not (e.g. upon
replacement of the wheel assemblies in
winter) and if compatible with the
country of purchase that makes this
possibility available. Then drive for at
least 20 minutes at a speed higher than
about 15 mph (25 km/h).
The TPMS will emit an acoustic warning,
warning light will flash for about
the
75 seconds, then will stay on constantly
and the instrument panel will display the
