Front Seat Belt
Assembly
Front seat belt tensioner,
removing and installing
The front seat belt locks are equipped
with pyrotechnic (explosive charge)
automatic tensioners. These tensioners
are designed to automatically retract
and tension the seat belt by 55 mm
(approximately 2 inches) in the event of
an accident.
WARNING!
Pyrotechnic seat belt tensioners
are powerful devices and should
be handled with extreme care.
Incorrect handling can trigger
the tensioner and cause injury.
BMW recommends that all repair
or replacement work on
pyrotechnic devices must be
carried out by a qualified BMW
technician.
Be sure to disconnect the
battery and wait 5 seconds
before attempting to work on
pyrotechnic devices.
Pyrotechnic devices cannot be
repaired. Always replace them.
Never treat pyrotechnic
components with cleaning
agents or grease.
