explosive manner, repairs must be performed by skilled personnel
only.
9 Warning
Adding accessories that change
the vehicle's frame, bumper
system, height, front end or side
sheet metal, may keep the airbag
system from working properly. The operation of the airbag system can
also be affected by changing any
parts of the front seats, seat belts,
airbag sensing and diagnostic
module, steering wheel,
instrument panel, inner door seals including the speakers, any of the
airbag modules, ceiling or pillar
trim, front sensors, side impact
sensors or airbag wiring.

pretensioner control electronics are
located in the centre console area.
Do not put any magnetic objects in
this area.
Do not affix any objects onto the
airbag covers and do not cover them with other materials. Have damagedcovers replaced by a workshop.
Each airbag is triggered only once.
Have deployed airbags replaced by
a workshop. Furthermore, it may be
necessary to have the steering
