II - TRIGGERING OF THE SAFETY SYSTEMS
Check the safety systems using the Diagnostic tool :
- after an accident,
- after theft or attempted theft of the vehicle,
- before selling a used vehicle.
The side impact sensors are fragile. When working in-
side the door box section, protect the sensor in order to
prevent any accidental damage (cardboard and adhe-
sive).
After detection of an impact, the airbag computer is de-
finitively locked and the « airbag fault » warning light il-
luminates on the instrument panel. The airbag
computer and the side impact sensors must always be
replaced.

the "Before repair procedure" using the

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 preten-
sioners: Recycling - Destruction, page 88C-10) .
III - DURABILITY OF THE PYROTECHNIC
COMPONENTS
The precautions which recommended that pyrotechnic
components (airbags and pretensioners) were re-
placed 10 years after the registration of the vehicle
have now been lifted.
Pyrotechnic components (airbags and pretensioners)
do not therefore require any maintenance.
