Observe the general safety instructions
for working on airbag, belt tensioner and
battery separation units (pyrotechnical
components)
WARNING
♦ Inspection, removal and installation and repair work must
only be carried out by properly qualified personnel.
♦ Only work described in this Workshop Manual must be
carried out. It is absolutely prohibited to disassemble the
airbag units.
♦ The fuel contained in pyrotechnical components is
burned, which produces gases. Furthermore, certain em‐
bodiments contain compressed gas which is used for the
gas production.
♦ This compressed gas is stored in a highly pressurised
pressure gas tank.
♦ The ignition of pyrotechnical components is carried out by
means of electrical/mechanical igniters.
♦ There are no change intervals for the airbag units.
♦ Under no circumstances use a test lamp, voltmeter or
ohmmeter for testing.
♦ Pyrotechnical components should only be checked when
installed and with a manufacturer-specified vehicle diag‐
nosis, measurement and information system.
♦ When working on pyrotechnical components and on the
airbag control unit - J234- , the earth strap of the battery
must be disconnected once the ignition is switched on.
Subsequently cover the negative terminal.
♦ After disconnecting the battery it is essential to wait 1 mi‐
nute.
♦ SWITCH ON the ignition before connecting the battery.
Nobody should be in the vehicle when the battery is con‐
nected. Exception: vehicles with the battery located in the
vehicle interior. In this case, you must not be in the range
of influence of the airbags and seat belts.
♦ If the vehicle is equipped with the Kessy system, the igni‐
tion should only be switched on after connecting the bat‐
tery using the ⇒ Vehicle diagnostic tester outside the
vehicle cockpit (the valid ignition key must be inside the
vehicle) for safety reasons. This procedure is part of the
test in the targeted fault finding.
♦ Wash your hands after touching the ignited pyrotechnical
components of the restraint system.
♦ Pyrotechnical components must not be opened or re‐
paired; always use new parts (risk of injury).
♦ Pyrotechnical components, which are damaged, must not
be re-installed.
♦ Defective airbag units of the airbag system which have not
been ignited must be returned for disposal to a specialist
company or to the importer in accordance with the instruc‐
tions of PST and environmental protection regulations.
The prescribed transport packaging must be used.
