Safety instructions for pyrotech-
nical, electrical and mechanical
components of the restraint
system
2.1
General safety instructions
Pyrotechnical components comprise:
◆
Airbag units
◆
Belt tensioners
◆
Belt force limiters
◆
Battery disconnecting elements
General
◆
Testing, installation and maintenance tasks must only be
carried out by trained personnel.
◆
There are no replacement intervals for airbag units.
◆
Do not check using circuit tester, voltmeter, or ohmmeter un-
der any circumstances.
◆
Pyrotechnic components must only be checked when instal-
led and using
⇒
vehicle diagnostic testers that have been
approved by the manufacturer.
◆
When working on pyrotechnic components and the airbag
control unit -J234-, the battery earth wire must be disconnec-
ted when the IGNITION is SWITCHED ON. The battery neg-
ative terminal must subsequently be covered.
◆
You must wait ten seconds after the battery -A- has been
disconnected.
◆
The battery -A- must be connected when the IGNITION is
SWITCHED ON. There must not be anybody inside the vehi-
cle during this process. Exception: vehicles with battery -A-
located inside the vehicle. Do not sit within the airbag and
seat belt deployment range.
◆
Observe the appropriate steps after connecting the bat-
tery
◆
Before performing any work on pyrotechnic components in
the restraint system, e.g. before disconnecting the electrical
connector, the mechanic carrying out the task must dis-
charge any static electricity. Electrostatic discharging can be
performed by touching earthed metal parts, e.g. by briefly
touching the door striker plate.
◆
Wash hands after touching ignited pyrotechnical compo-
nents of the restraint system.
◆
Pyrotechnical components must neither be opened nor re-
paired. New parts must always be used (risk of injury).
◆
Pyrotechnic components that have fallen onto a hard surface
or that show any sign of damage must not be installed.
