Airbags
The most effective occupant restraint
system yet developed for use in
production vehicles is the three point
seat belt. In some cases, however, the
protective effect of a seat belt can be
further enhanced by an airbag.
The driver airbag (1) is located in the
steering wheel hub. The passenger
airbag (2) is located in the dashboard
ahead of the passenger. In conjunction
with wearing the seat belts with
emergency tensioning retractors (4),
they provide increased protection for
the driver and passenger.
The operational readiness of the airbag
system is verified by the indicator
lamp "SRS" (3) in the instrument
cluster. If no fault is detected, the lamp
will go out after approximately 4
seconds; after the lamp goes out, the
system continues to monitor the
components and circuitry of the airbag
system and will indicate a malfunction
by coming on again.
