IMPORTANT
To avoid any risk of triggering when working on
or near a pyrotechnic component (airbags or pre-
tensioners), 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 (igni-
tion on).
IMPORTANT
Never handle the pyrotechnic systems (preten-
sioners or airbags) near to a source of heat or
naked flame - they may be triggered.
