for malfunctions. The light tells you if there is
an electrical problem. The system check includes
the airbag sensors, the airbag modules, the
wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, see Airbag System on page 90.

when you start your
vehicle, and it will flash
for a few seconds.

If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly.

inflate in a crash, or they could even
inflate without a crash. To help avoid
injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start
your vehicle.

start the vehicle or comes on when you are driving,
your airbag system may not work properly.

seconds when you turn the ignition key to RUN.
If the light does not come on then, have it fixed so
it will be ready to warn you if there is a problem.
