Tire Pressure Monitoring System (Tpms) - Alfa Romeo GIULIA 2022 Owner's Manual

T P M
IRE RESSURE ONITORING
(TPMS)
The vehicle is equipped with a TPMS that sends
the inflation pressure information of each tire to
the control unit, and will signal the driver in the
event of insufficient tire pressure.
The TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure
readings to the receiver module.
Tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will
also decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle has
not been driven for at least three hours, or driven
less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also
increase as the vehicle is driven. This is normal,
and there should be no adjustment for this
increased pressure. See
Ú
information on how to properly inflate the
vehicle's tires.
The TPMS will signal the driver if pressure falls
below the warning limit for any reason, including
the effects of low temperature and normal loss of
pressure from the tire.
The TPMS will stop indicating insufficient tire
pressure when pressure is equal to or greater
than the prescribed cold inflation level.
Therefore, if insufficient tire pressure is indicated
142
S
by the (
YSTEM
instrument cluster, increase the inflation
pressure up to the prescribed cold inflation value.
The system will automatically update, and the
Tire Pressure Monitoring System Warning Light
will turn off once the system receives the updated
tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
NOTE:
The TPMS cannot indicate sudden tire pressure
drops (e.g. if a tire bursts). In this case, proceed
with caution and avoid abrupt steering.
Operating Example
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa). If
the ambient temperature is 68°F (20°C), and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn
on the Tire Pressure Monitoring System Warning
Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
page 206 for
System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are
inflated to the vehicle's recommended cold
placard pressure value.

CAUTION!
The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures
and warning have been established for the
tire size equipped on your vehicle.
Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type,
and/or style. The TPMS sensor is not
designed for use on aftermarket wheels and
may contribute to a poor overall system
performance or sensor damage. Customers
are encouraged to use Original Equipment
Manufacturer (OEM) wheels to ensure proper
TPMS feature operation.
Using aftermarket tire sealants may cause

the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure

always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the Tire Pressure Monitoring
System Warning Light in the instrument cluster
will display alongside the dedicated messages,
the system will highlight the tire or tires with
insufficient pressure graphically, and an acoustic
signal will be emitted.
