Front seat refitting
26
Refitting is a reverse of the removal pro-
cedure, noting the following points:
a) Remove all
traces
of old thread-locking
compound from the threads of the seat
retaining bolts, and clean the threaded holes
in the vehicle floor, ideally by running
a
tap of
the correct size and pitch down them.
b) Apply a suitable thread-locking
compound to the threads of the seat

bolts (arrowed)

lift
off the seat guide cover
bolts. Refit the bolts, and tighten them to

c) Reconnect the
seat
wiring connector
making sure it has locked securely, then
reconnect the battery negative terminal.
Rear seat refitting
27 Refitting is a reverse of the removal pro-
cedure.
All models covered in this manual are
fitted with a front seat belt pyrotechnic
tensioner system. The system is designed to
instantaneously take up any slack in the seat
belt in the case of a sudden frontal impact,
therefore reducing the possibility of injury to
the front seat occupants. Each front seat is
fitted with its own system, the components of
which are mounted on the seat frame.
The seat belt tensioner is triggered by a
frontal impact causing a deceleration of six
times the force of gravity or greater. Lesser
impacts, including impacts from behind, will
not trigger the system.
When the system is triggered, a
pretensioned spring draws back the seat
belt via a cable which acts on the seat belt
stalk. The cable can move by up to 80.0 mm,
which therefore reduces the slack in the seat
belt around the shoulders and waist of the
occupant by a similar amount.
There is a risk of injury if the system is
triggered inadvertently when working on
the vehicle, and it is therefore strongly
recommended that any work involving the
seat belt tensioner system is entrusted to a
Vauxhall/Opel dealer. Refer to the warning
given at the beginning of Section 23 before
contemplating any work on the front seats.
Warning: The front seats are
fitted with pyrotechnic seat belt
tensioners which are triggered by
