Tire pressure monitoring system
It may occur that the system does not
know which wheel is signaling the
fault and it is hence unable to display
it: page 10 will be displayed for 10
seconds.
The system calculates the residual tire
life and repeats the display cycle every
19 mi (30 km) of driving up to a
maximum of 75 mi (120 km) and also
controls the conditions of exceeding
the maximum km travelled or
exceeding the speed limit.
System not calibrated
If the system has not been calibrated or
following a tire replacement, the
warning light will flash on the
instrument panel for 90 seconds, and
the display will show screen page 11.
Subsequently, the screen page
previously active is displayed once
again and the warning light
illuminates on the instrument panel
permanently.
The system can be calibrated by means
of the specific button (see page 47).
The information page that shows the
pressure value for each tire cannot be
recalled by the user.
Tire pressure monitoring system
failure
Screen page 12 may appear in the
following cases:
– malfunction in the ECU system/
wiring
– no signal reception by one or more
sensors due to malfunction,
breakage or dead battery;
– ECU malfunction.
The display sequence follows the usual
logic of malfunctions. Therefore, after
10 seconds, the display will show the
screen page that was active before the
malfunction occurred.
