Tyre pressure monitoring system
(optional)
The vehicle can come equipped with a
system that monitors the tyre pressure by
means of special sensors fitted inside the
wheel rims, in position with the inflation
valve.
These sensors transmit a signal that is
detected by the antennas fitted 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 tyre
pressure data and any system errors to the
on-board instrument panel.
The signal transmitted by the ECU activates
some 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 0.2 bar, and
a hard warning, if it is greater than 0.4 bar
or if there is a dynamic decrease over 2.9
psi/min.
The system is equipped with a specific
wiring that connects the antennas, the ECU
and the calibration button (positioned
under the dashboard, on the left-hand side
of the steering wheel) to the vehicle electric
system.
Tyre pressure calibration button
To calibrate the system, with the ignition
key in position II, press the button located
on the left, lower part of the dashboard,
holding it for 4-10 seconds: the symbol
will appear on the multi-function
CAL
display.
The system will take a maximum of 20
minutes to complete the setting procedure
with the vehicle in motion.
If the difference in pressure between the
wheels on the same axle exceeds 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
138).
6 - Technical Information
The system must be calibrated using
the button on the dashboard after tyre
replacement or inflation.
The system warns the driver that
there is a drop in tyre pressure,
page
however, this does not exempt the driver
from periodically checking that the tyres
are inflated to the specified pressure (see
label on page 10).
Moreover, the system does not inform the
driver about damage to the tyres caused by
external agents.
