harmless and does not indicate the
beginning of a fire. The dust may irritate
the skin and eyes however: in this
case, wash with neutral soap
and water.
Airbag checking, repair and
replacement must be carried out at an
Alfa Romeo Dealership.
If the car is scrapped, have the airbag
system deactivated at an Alfa Romeo
Dealership.
Pretensioners and airbags are deployed
in different ways, according to the
type of impact. Failure to deploy of one
of the devices does not necessarily
indicate a system malfunction.
