Tyre Pressure And Temperature Monitoring System; Displaying Messages On The “Tft” Display - Ferrari California Owner's Manual

Tyre pressure and temperature
monitoring system
The vehicle is equipped with a system that measures tyre pressure
and temperature using special sensors fixed inside the wheel rims
next to the air valve. These sensors send a signal that is received by
the antennas fixed to the body behind the gravel guards that are
connected to the ECU.
Important note
The system may be momentarily affected by radioelectrical
interference from devices that use similar wavelengths.
The ECU processes this information and transmits data on tyre
pressure and temperature and any system errors to the instrument
panel via a CAN line.
The signal transmitted by the ECU activates symbols on the TFT
display with two priority levels: a soft warning (sw) if the pressure
loss compared with the nominal pressure exceeds 0.2 bar and a
hard warning (hw) if it exceeds 0.5 bar or there is a dynamic loss
of over 0.2 bar/min.
The system can be calibrated using the special menu item in the
TFT display (see page 123).
Important note
System calibration using the special menu item on the TFT
display is necessary after replacement or inflation of a tyre or
tyres.
Warning
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.
In addition, the system does NOT warn the driver of damage to
the tyres by external agents.
Displaying messages on the "TFT" display
By pressing a special DISP button, the driver can access the
TYRES screen page that shows the pressure and temperature
values of each tyre as in the following example 1.
The TYRES screen page can be set as the standard screen page
(see page 127).
