PRE-TENSIONING DEVICES

To increase the efficiency of the front seat
belts, Alfa 156 is fitted with pre-tension-
ing devices. These devices "feel" that the
car is being subject to a violent impact by
way of a sensor rewind the seat belts a few
centimetres. In this way they ensure that
the seat belt adheres to the wearer before
the restraining action begins.
The seat belt locks to indicate that the de-
vice has intervened; the seat belt cannot be
drawn back up even when guiding it man-
ually.
WARNING The pretensioner will give
maximum protection when the seat belt ad-
heres snugly to wearer's chest and hips.
A small amount of smoke may be pro-
duced. This smoke is in no way toxic and
presents no fire hazard.
The emergency tensioning retractor needs
no maintenance or lubrication. Any modifi-
cation to its original features will nullify the
retractor's effectiveness. If, due to unusual
natural events (floods, high waves, etc.),
the device has been affected by water and
mud, it must be replaced.
WARNING
The pretensioner can only
be used once. After a col-
lision that has triggered it, have it
replaced at Alfa Romeo Authorized
Service. The validity of the device
is written on the plate located on
the front left door near the lock.
Contact Alfa Romeo Authorized
Services to have pretensioner re-
placed as this date approaches.
Operations
banging, vibrations
heating (above 100°C for
a maximum of 6 hours) in the area
of the pretensioners may damage
or trigger off the device. Vibrations
from rough road surfaces or acci-
dental jolting caused by mounting
pavements etc. do not have any ef-
fect on the pretensioner. If, how-
ever, you need assistance, go to
Alfa Romeo Authorized Services.
