on when travelling, check that the handbrake is not engaged.
With handbrake engaged, if 4 km/h speed is exceeded the buzzer will sound (only for versions with reconfigurable multifunction display).

turns on when
travelling (on certain versions together with the message on the display) stop the
car immediately and contact Fiat Dealership.
