Tire pressure monitoring system
(optional)
The vehicle can be equipped with a system
that measures the tire pressure through
special sensors fi tted on the inside of the
wheels, in the position of the infl ation valve.
These sensors transmit a signal that is
detected by the antennas fi tted behind the
gravel guards and connected to the ECU.
The system can momentarily experience
radio-electric interference emitted by
devices using similar frequencies.
The ECU processes this information and,
via the CAN line, transmits a series of tire
pressure data and system errors, if any, to
the instrument panel.
The signal transmitted by the ECU
illuminates symbols on the multi-function
display with two priority levels: a soft
warning, if the pressure decrease with
respect to the rated pressure is greater than
2.9 psi (0.2 bar), and a hard warning, if it is
greater than 5.8 psi (0.4 bar) or if there is
a dynamic decrease over 2.9 psi/min. (0.2
bar/min).
The system is wired so that the antennas,
the control unit and the calibration button
are connected to the electrical system of the
vehicle, positioned on the left lower part of
the dashboard.
Tire pressure calibration button
To calibrate the system, turn the ignition
key to position II , press the button located
on the left lower part of the dashboard,
holding it for 4-10 seconds: the CAL
symbol will appear on the multi-function
display.
The system will take a maximum of 20
minutes to complete the calibration
procedure with the vehicle in motion.
If the difference in pressure between the
wheels on the same axle exceeds 5.8 psi
(0.4 bar), the system will not calibrate.
If the system detects a pressure drop during
calibration, the relevant symbol will appear
on the multi-function display (see page
146 ).
The system must be calibrated using the
relevant button on the dashboard after tire
replacement or infl ation.
The system warns the driver that
there is a drop in tire pressure,
however, this does not exempt the driver
from periodically checking that the tires are
infl ated to the specifi ed pressure (see label
on page 12 ).
Moreover, the system does not inform the
driver about damage to the tires caused
by external agents (e.g., acid or adhesive
substances on the road, stones, nails etc.)
