Tyre Pressure Monitoring System (Optional Equipment) - Maserati GRANCABRIO Owner's Manual

Tyre pressure monitoring
system
(optional equipment)
On request, the vehicle may come
equipped with a system that monitors
the tyre pressure by means of special
sensors fi tted inside the wheel rims,
in position with the infl ation valve.
These sensors transmit a signal that
is detected by the antennas installed
on the vehicle body behind the gravel
guards and connected to the ECU.
WARNING: The system can
momentarily experience radio-electric
interference emitted by devices using
similar frequencies.
A
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 display may show the information
received by means of specifi c screen
pages, which can be recalled selecting
the "Tyre Pressure" page.
The system warns the driver
that the tyre pressure has
decreased. This warning
does not exempt the driver from
periodically checking the tyres and
from complying with the prescribed
tyre pressure levels.
WARNING: The system stores the
tyre pressures as a reference rate,
therefore tyres must be infl ated to
the prescribed pressure.
B
System calibration
The system must be calibrated:
- after replacing one or more tyres;
- after inverting the wheels;
- if you are not sure whether at least
one of the operations above was
performed.
If you simply corrected the tyre
infl ation 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 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.
