Driver Airbag
The most effective occupant re­
straint system yet developed for
use in production vehicles is the
three-point seat belt. In some
cases, however, the protective
effect of seat belts can be further
enhanced by an airbag.
The airbag (1) is located in the
steering wheel hub and, in con­
junction with wearing the seat
belts with emergency tensioning
retractors (2), provides increased
protection for the driver.
The operational readiness of the
airbag system is verified by the
indicator lamp " SR S" (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.
