SAFETY
67
The system receives signals relative to tyre pressure and temperature from
an antenna connected to the TPMS 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. The
signal transmitted by the ECU activates symbols on the left TFT display
with two priority levels: a soft warning (sw) if the pressure measured is
slightly lower than the nominal value, and a hard warning (hw) if the loss
of tyre pressure is critical for vehicle safety.
The TPMS system may be calibrated from the relative option in the left
hand TFT display menu Left Hand TFT Display
Important note
System calibration using the special menu item on the left TFT display
is necessary after replacement or inflation of a tyre or tyres.
Warning
The TPMS warns the driver that the tyre pressure has decreased.
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.
