I - PRECAUTIONS FOR REPAIR
IMPORTANT
All operations on airbag and pretensioner systems must be carried out by qualified trained personnel.
The airbags have a pyrotechnic gas generator, with an ignition module and bag which must not be separated.
The pretensioners have a pyrotechnic gas generator and an igniter which must, under no circumstances, be separated.
IMPORTANT
Never handle the pyrotechnic systems (pretensioners or airbags) near to a source of heat or naked flame - they may be triggered.
IMPORTANT
To prevent any accidental triggering whilst working on or near a pyrotechnic component (airbags or pretensioners), lock the airbag computer using the Diagnostic tool.
When this function is activated, all the trigger lines are inhibited and the airbag warning light on the instrument panel lights up continuously (ignition on).
(see Fault finding - Replacement of components) (88C, Airbag and pretensioners).
When working underneath the vehicle (on the bodywork, sill panel, etc.) or for certain operations involving removal or refitting of seat trims, it is essential to lock the airbag computer using the Diagnostic tool and to disconnect the battery (see 80A, Battery, Battery: Removal - Refitting, 80A-1).
IMPORTANT
To prevent the pyrotechnic components from being permanently deactivated or triggered (airbags or pretensioners), check the airbag computer using the Diagnostic tool.
The pyrotechnic systems (pretensioners and airbags) must be checked using the Diagnostic tool :
II - TRIGGERING OF THE SAFETY SYSTEMS
IMPORTANT
In order to prevent interference with the deployment of the airbags:
After detection of an impact, the airbag computer locks definitively and the " airbag fault " warning light is illuminated on the instrument panel. The airbag computer and the side impact sensors must always be replaced.
IMPORTANT
To eliminate the risk of any accident, do not reuse pyrotechnic components.
It is essential to destroy pretensioners or airbags before scrapping a vehicle or a part only (see 88C, Air bag and Pretensioners, Airbags and pretensioners: Recycling - Destruction, 88C-7).
III - DURABILITY OF THE PYROTECHNIC COMPONENTS
The precautions which recommended that pyrotechnic components (airbags and pretensioners) were replaced 10 years after the registration of the vehicle have now been lifted.
Pyrotechnic components (airbags and pretensioners) do not therefore require any maintenance.
