Safety precautions when working on
airbags
Testing, removing, installing and repair work
may only be performed by qualified technicians.
When working on airbag system, battery ground
(GND) strap must be disconnected. No waiting
time is necessary after disconnecting the
battery. When connecting airbag system to a
voltage source no person can be present inside
the vehicle.
Technicians must electrostatically discharge
themselves by touching a suitable metal part,
for example, a water pipe, heater pipe or metal
frame, before picking up (touching) airbag unit.
Airbag units should be installed immediately
after removing them from their packaging.
If work is interrupted, airbag unit should again
be placed in its packaging.
Do not leave airbag unit unattended.
69-33
Airbag units which have been removed should
be stored so that upholstered side is facing up.
Airbag units which have dropped onto a hard
surface or show signs of damage must not be
installed in the vehicle.
Airbag units which have not been activated
should be marked and returned to manufacturer
for disposal in original airbag unit transport
containers.
Storage and transportation of airbags must
comply with the Explosives Act.
Only install original seat covers that have been
authorized for use with side airbags
(recognizable by airbag label).
Use of commercially-available loose-fitting
covers is not permissible.
When installing backrest cover ensure that
cover seam is straight in area of side airbag.
Always replace all cover clips.
Only use original clips.
Always replace cover if damaged in area of side
airbag - torn, burn holes etc.- for safety
reasons.
69-34
Supplemental side airbag protection safety
precautions
Do not repair damaged pillar trim panels; they
must be replaced.
Side curtain protection must not be buckled or
warped.
After body repair in area around side curtain
protection, look over vehicle body for weld
splatter, deformities and abrasions, and use
other side of vehicle for comparison.
Replacing airbag units following
accidents
Accident involving activation of airbag
Always replace the following:
All triggered airbag units with control units and
sensors
Support for front passenger module
Coil connector with slip ring
All seat belts with triggered belt tensioners
In addition, the following must also be replaced
if necessary (visual check): All damaged
components
69-35
Accident not involving activation of airbag
If Airbag Malfunction Indicator (MIL) -K 75 does
not indicate a fault, it is not necessary to
replace airbag components. Seat belts should
be checked separately.
After replacing airbag units or the control unit,
affix stickers (only tear-off strips) to registration
card and return registration card to relevant
dealer or to Importer for registration.
The registration card must be ordered
separately.

Airbag units, deploying (disposal)
WARNING!
DO NOT ignite airbag units in vehicles.
According to regulations, airbag units must be
rendered unusable by igniting them electrically
before scrapping the vehicle. This is necessary
because the airbag unit is a pyrotechnic device
that may cause injuries if activated in an
improper manner (e.g. using a cutting torch).
- Remove airbag unit
Page 69-36
Use J-44210 Deployment Fixture and refer to the
Airbag & Pyrotechnic Deployment Device
Instruction Booklet for proper deployment
procedure.
