Tire punctures

When the instrument panel receives a
signal from the tire pressure ECU
indicating that the pressure level of
one or more tires is below the alarm
threshold, the warning light
permanently illuminate on the
instrument panel and screen pages 4

will alternate on the display for 20
seconds. Every time the key is
subsequently turned back to ON, if the
malfunction persists the display will
show screen pages 4 for 20 seconds.
These screen pages will be displayed
until the situation is corrected and the
system is calibrated again as required
by the system.

Tire pressure monitoring system
The system may not know what wheel
is originating the malfunction and
therefore is not capable of indicating
the wheel involved. As a consequence,
in addition to the warning light
permanently illuminated on the
will
instrument panel, the display will show
screen page 5. The display strategy of
this screen page follows the same logic
applied for screen page 4, previously
described.

"Run Flat" tire puncture
If the vehicle is equipped with Run Flat
tires, in the event of a tire puncture,
the relative warning light comes on
and the pages 6 are alternately
displayed for 10 seconds. At the end of
the display cycle, the system will show
the previously active page with the
symbol positioned in area G of the
display (see page 76). The warning
light on the instrument panel
remains on.
The system calculates the residual tire
life in miles and repeats the display
cycle every 19 mi (30 km) of driving up
to a maximum of 75 mi (120 km).
