For welded connections in three thicknesses, the
spot welds on the part replaced should be made in
the same place as for the original joint to retain its
mechanical proper ties.

IMPORTANT
To avoid damaging the vehicle's electric and elec-
tronic components, the battery and the earths of
any wiring harness near the weld area must be dis-
connected.
The earth of the welding machine must be placed
as close as possible to the weld area.

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.
