pressure monitoring system

The vehicle is equipped with a system
that monitors the tyre pressure by means
3
of special sensors secured inside the
wheel rims, in position with the inflation
valve. These sensors transmit a signal
that is detected by the antennas fastened
on the car body, 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 system errors, if any,
to the 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 decrease in pressure,
with respect to the rated pressure,
greater than 0.2 bar, and a
if it is greater than 0.4 bar
a dynamic decrease greater than 0.2
bar/min.
48
The system is wired so that the antennas,
the ECU and the calibration button
are connected to the electric system of
the vehicle. This wiring is positioned
on the dashboard, next to the engine
compartment lid opening lever (see on
page 61).
The system must be calibrated using
the button on the dashboard after tyre
replacement or inflation.
CAUTION
The system warns the driver that there
is a drop in tyre pressure. However,
this does not exempt the driver from
periodically checking that the tyres are
inflated to the indicated pressure (see
label on page 13).
In addition, the system does not
inform the driver of sudden damage
to tyres caused by external objects/
agents.

The symbol colour defines the priority:
Green: normal conditions of use
Red:
when a fault has been detected
Amber: when the driver is requested to
check the system.
The following symbols will appear to
identify each wheel; the "solid" square
indicates the tyre involved:
• FL front left-hand wheel
• RL rear left-hand wheel
• RR rear right-hand wheel
• FR front right-hand wheel
Pressure indication for each tyre
It can be activated by pressing
the scroll button on the multi-
function display (see on page 62) to view
the pressure of each tyre.
If requested when the data is not
available, (e.g., during the calibration
procedure) the symbols will be shown
with " _ . _ " instead of the value.
