Airbags
1 Driver airbag
2 Front passenger airbag
3 Side impact airbag
The most effective occupant re
straint system yet developed for
use in production vehicles is the
seat belt. In some cases, however,
the protective effect of a seat belt
can be further enhanced by an
airbag.
The driver airbag is located in the
steering wheel hub. The passenger
airbag is located in the dashboard
ahead of the passenger.
The side impact airbags are locat
ed in the front doors. In conjunction
with wearing the seat belts with
emergency tensioning retractors,
the airbags can provide increased
protection for the driver and
passenger in certain major frontal
or rear impacts (for front airbags),
and side impacts (for side impact
airbags).
The operational readiness of the
airbag system is verified by the in
dicator lamp “SRS” in the instru
ment cluster. If no fault is detected,
the lamp will go out after approxi
mately 4 seconds; after the lamp
goes out, the system continues to
monitor the components and
circuitry of the airbag system
andwill indicate a malfunction by
coming on again.
The following system components
are monitored or undergo a self
check: crash-sensor(s), airbag igni
tion circuits, front seat belt buckles,
emergency tensioning retractors,
seat sensor (when present).
Initially, when the key is turned
from steering lock position 0 to
positions 1 or 2, malfunctions in the
crash-sensor are detected and
indicated (the “SRS” indicator lamp
stays on longer than 4 seconds). In
the operational mode, after the
