vehicle, that prevent the TPMS from
functioning properly. Always check
the TPMS malfunction warning light
after replacing one or more tires or
wheels on your vehicle, to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
System calibration
The system must be calibrated:
- after replacing one or more tires
- after inverting the wheels
- if you are not sure whether at least
one of the operations above was
performed.
If you simply corrected the tire
inflation pressure, you do not need to
recalibrate the system.
To calibrate the system, select the
screen page “TPMS calibration”
by pressing the MODE button
A .
Subsequently press and hold button
“+”
B to activate the calibration
procedure.
This operation may be performed
with the key at
MAR (ON) and the
engine off. The system will take a few
seconds to complete the process, and
during this time the green symbol
and the message “Calibration started”
will be displayed.
If the user recalls the information
page showing the pressure levels
of each tire, dashes “--.--“ will be
displayed in the place of the values.
WARNING: The system will not
perform calibration if the pressure is
below 29 PSI (2 bar).
Viewing messages on the
display
By pressing the MODE button A
repeatedly (see on page 74), the user
can access the information page that
shows the pressure values of each tire
(“Tire Pressure” page).
If system faults are found when
this page is recalled, the same page
will be replaced by an information
message on the problem found. Also
in this case, the information message
will be displayed for a preset time.
When the display time has elapsed,
the “Tire Pressure” screen page
becomes available again, but the
summary symbol for the malfunction
will remain displayed in the dedicated
area, until the malfunction is
corrected.
