Safety
Tyre temperature and pressure monitoring
system ( TPMS) (optional)
On request, the vehicle can be equipped with a system that
measures the tyre pressure and temperature using special sensors
fi tted inside the wheel rims next to the air valve. These sensors
transmit a signal that is received by the antennas on the car 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.
The signal transmitted by the ECU activates symbols on the left
TFT display (see page 96) with two priority levels: a
soft warning
(SW) if the pressure loss is 0.2 bar more than the rated pressure
and a hard warning (HW) if it is 0.5 bar more or there is a
dynamic decrease of over 0.2 bar/min.
The TPMS can be calibrated using the special menu item in the left
TFT display (see page 98).
Important note
System calibration using the special menu item on the left TFT
display is necessary after replacement or infl ation 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 infl ated 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 left TFT display
By using the commands on the left TFT display (see page 96), the
driver can access the TYRES screen page which displays the vehicle
symbol with the pressure and temperature values of each tyre as
shown in example
