The most effective occupant restraint

turning the electronic key in steering
lock to position 1 or 2. 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.
The following system components are
monitored or undergo a self-check:
crash-sensor(s), airbag ignition circuits,
front seat belt buckles, emergency
tensioning retractors, seat sensor.

turned from steering lock position 0 to
positions 1 or 2, malfunctions in the

indicated (the "SRS" indicator lamp
stays on longer than 4 seconds).
In the operational mode, after the
indicator lamp has gone out following
