nents) (88C, Airbags and pretensioners).
(see 88C, Air bag and Pretensioners, Airbags
and pretensioners: Recycling - Destruction,
page 88C-2) . IMPORTANT
After a seat belt pyrotechnic component is trigge-
red, it is essential to replace certain parts.
(see 88C, Air bag and Pretensioners, Airbag
and pretensioners: Precautions for the repair,
page 88C-1) .
IMPORTANT
When the passenger front airbag is triggered, the
consequent damage caused to the mountings
always requires the dashboard to be replaced.
Affix the label warning against fitting a rear-facing
child seat on the front passenger seat to the pas-
senger side of the dashboard.
Note:
Check that the passenger's front airbag is braced
against the dashboard cross member.

IMPORTANT
To avoid a fault with or even triggering of pyro-
technic components (airbags or pretensioners),
check the airbag computer using the diagnostic
tool.
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 the single part.

aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (MR 411, 02A, Lifting equip-
ment).
aLock the airbag computer using the Diagnostic tool
(see Fault finding - Replacement of components)
(MR 413, 88C, Airbags and pretensioners).
aDisconnect the battery (see 80A, Battery, Battery:
Removal - Refitting, page 80A-2) .
