Turning the ignition key to MAR the warning light on the dial turns on, but it should go off after few seconds. The warning light stays on glowing steadily (on certain versions together with the message on the display) if there is a failure in the air bag system.
WARNING
If the 
warning light does not turn
on when turning the ignition key to MAR or if it stays on when travelling, this
could indicate a failure in safety retaining systems; under this condition air bags
or pretensioners could not trigger in the event of collision or, in a restricted
number of cases, they could trigger accidentally. Stop the car and contact Fiat
Dealership to have the system checked immediately.
WARNING
The failure of the 
warning light
(warning light off) is also indicated by the flashing for more than the normal seconds
of the passenger’s front air bag deactivated warning light
.
