Pre-Tensioning Devices - Alfa Romeo 147 Owner's Manual

PRE-TENSIONING DEVICES

To increase the efficiency of the front seat
belts, the car is fitted with pre-tensioning de-
vices. These devices "feel" that the car is
being subject to a violent impact by way of
a sensor and 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 pre-
tensioner has intervened; the seat belt can-
not be drawn back up even when guiding
it manually.
IMPORTANT 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 pretensioner needs no maintenance or
lubrication. Any modification to its original
features will nullify the retractor's effective-
ness. If, due to unusual natural events
(floods, high waves, etc.), the device has
been affected by water and mud, it must be
replaced.
WARNING
Pre-tensioning devices can
only be used once. After
they have been triggered contact
Alfa Romeo Authorised Services to
have them replaced. The validity of
the device is shown on the plate
fitted on the front left door near
the lock; the pretensioners should
be changed at an Alfa Romeo Au-
thorised Service as this date ap-
proaches.
Operations involving
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 Al-
fa Romeo Authorised Services.
WARNING
Never disassemble or tam-
per with the pretensioner
components. All interventions must
be carried out by qualified and au-
thorised personnel. Always contact
Alfa Romeo Authorised Services.
