This warning light
will illuminate to indicate a fault with the air bag, and will turn
on for four to eight seconds as a bulb check when the ignition is
placed in the ON/RUN or ACC/ON/RUN position. This light will illuminate
with a single chime when a fault with the air bag has been detected,
it will stay on until the fault is cleared. If the light is either
not on during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible.
