IMPORTANT
Consult the safety and cleanliness advice and ope-
ration recommendations before carrying out any
repair (see 88A, Wiring harness, Wiring: Precau-
tions for the repair, page 88A-2) .
IMPORTANT
To avoid any risk of triggering when working on or

are inhibited and the airbag warning light on the ins-
trument panel lights up contin uously (ignition on).
IMPORTANT
Never handle the pyrotechnic systems (pretensio-
ners or airbags) near to a source of heat or naked
flame - they may be triggered.
WARNING
To prevent damaging the connectors, consult the
disconnection procedures (see Connector: Dis-
connection and reconnection) (Technical Note
