stays
on
.
When
the
ignition
key
is
tumed
on,
the
indicator
light
will
illu-
minate
for
approximately
4-6
seconds
.
The
illuminated
light
indicates
the
self-testof
the
electronic
control/monitoring
module,
the
ignítors
and
crash-sensorcircuits,
and
the
system
wiring
.
The
airbag
system
should
be
inspected
byan
autho-
rized
BMW
dealer
if
the
indicator
light
does
not
come
on,
ifit
does
not
go
out
in
approximately
4-6
seconds
after
switching
onthe
ignition,
or
if
the
light
comes
on
during

the
light
will
come
on
and
stay
on
