PRETENSIONERS
To increase the efficiency of the front
seat belts, the Alfa 166is fitted with
pretensioners.
These devices “feel”, through a sensor,
that a violent crash is in progress and
rewind the seat belts a few centimetres.
In this way they ensure that the seat belt
adheres perfectly to the wearer before
the restraining action begins.
The seat belt locks to indicate that the
device has intervened; the seat belt can-
not be drawn back up even when guiding
it manually.
IMPORTANTTo obtain the highest
degree of protection from the action of
the pretensioning device, wear the seat
belt keeping it firmly close to the chest
and pelvis.
A small amount of smoke may be pro-
duced. This smoke is in no way toxic and
presents no fire hazard.The pretensioner does not require any
maintenance or greasing. Anything that
modifies its original conditions invalidates
its efficiency. If due to unusual natural
events (floods, sea storm, etc.) the de-
vice has been affected by water and
mud, it must necessarily be replaced.
After adjustment, always
check that the slider is
anchored in one of the positions
provided. To do this, with the but-
ton (A-fig. 52) released, exert a
further pressure to allow the an-
chor device to catch if release did
not take place at one of the preset
positions.
WARNING
The pretensioner can only
be used once. After a col-
lision that has triggered it, have it
replaced at an Alfa Romeo Autho-
rized Services. The validity of the
device is 10 years starting from
the date of production, the preten-
sioners should be replaced at an
Alfa Romeo Authorized Services as
this date approaches.
WARNING
This precaution could greatly reduce the
risk of injury in case of collision.
Correct adjustment is obtained when the
belt passes half way between the end of
the shoulder and the neck.
4 different adjustments in height are
provided.
To adjust the attachment raise or lower
the grip (A-fig. 52) and ring (B-
fig. 52) to one of the set positions.
