Operating Example - Alfa Romeo Giulia 2017 Owner's Manual

"Tires" in "Servicing And Maintenance"
for information on how to properly
inflate the vehicle's tires. The tire
pressure will also increase as the
vehicle is driven. This is normal, and
there should be no adjustment for this
increased pressure.
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 by the (
displaying in the instrument cluster,
increase the inflation pressure up to the
prescribed cold inflation value.
The system will automatically update,
and the "Tire Pressure Monitoring
Telltale 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.

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 Warning
Light." Driving the vehicle may cause
the tire pressure to rise to
approximately 28 psi (193 kPa), but the
"Tire Pressure Monitoring Telltale Light"
will still be on. In this situation, the "Tire
Pressure Monitoring Warning Light" will
) warning light
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 TPM
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 OEM wheels to assure proper TPM
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.
